for the first table to find the equation of its line you need to find the gradient(m). to do that you take 2 points then subtract the first y from the second y. so 12-9=3 then do the same with the x so 5-2=3 then divide the first by the second and 3÷3=1 so the gradient(m) is 1. so the equation is in the form y=mx+c and since we know m is 1 the equation will be y=x+c. to find c we take a point on the line and replace the numbers so 9=2+c must be true and for it to be true c must be 7. so the equation of the line is y=x+7. also pls mark as brainliest answer

de los animales que hay en un corral la mitad son gallinas, la quinta parte patos, la novena parte pavos y 510 son pollos ¿cuantos animales hay en el corral?
The number of animals there are in the corral is 1020.
We are given that Number of chicken=510
This is a word problem that can be solved by using fractions and proportions.
Let x be the total number of animals in the corral. Then, according to the problem, we have:
x/2 = 510 (half are chickens) x/5 = ? (a fifth are ducks) x/9 = ? (a ninth are turkeys)
To find the total number of animals, we need to find a common denominator for the fractions and add them up. The least common multiple of 2, 5, and 9 is 90, so we multiply each fraction by 90 to get:
45x/90 = 45 * 510 (half are chickens) 18x/90 = ? (a fifth are ducks) 10x/90 = ? (a ninth are turkeys)
Adding up the fractions, we get:
(45x + 18x + 10x)/90 = 73x/90
This is the fraction of animals that are chickens, ducks, or turkeys. To find the total number of animals, we need to divide both sides by 73/90, which is equivalent to multiplying by 90/73. We get:
x = (73x/90) * (90/73) x = x
Therefore, the total number of animals in the corral is x.
To find the value of x, we can use the equation x/2 = 510 and solve for x. We get:
x/2 = 510 x = 510 * 2 x = 1020
Therefore, by unitary method the answer will be 1020.

What lump sum should be deposited in an account that will earn 9% compounded every 2 months, to grow to $100,000 in 32 years? Show your step process, when you are solving the problem.
Answer:
We should deposit approximately $14,408.92 in the account to grow to $100,000 in 32 years, assuming a 9% annual interest rate compounded every 2 months.
Step-by-step explanation:
To solve this problem, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the future value of the investment
P = the initial principal (the lump sum we need to deposit)
r = the annual interest rate (9% in this case)
n = the number of times the interest is compounded per year (since interest is compounded every 2 months, or 6 times per year, n = 6)
t = the number of years (32 years in this case)
We are given that we want the investment to grow to $100,000 in 32 years, so we can set A = $100,000 and solve for P:
$100,000 = P(1 + 0.09/6)^(6*32)
Simplifying the expression inside the parentheses:
$100,000 = P(1.015)^192
Dividing both sides by (1.015)^192:
P = $100,000 / (1.015)^192
Using a calculator:
P ≈ $14,408.92
Therefore, we should deposit approximately $14,408.92 in the account to grow to $100,000 in 32 years, assuming a 9% annual interest rate compounded every 2 months.

Find the missing angle. Enter only a value. Round to the nearest degree (whole number). Hint: use inverse trig. Your answer should be an odd number. Thank you!
The missing angle is approximately 67 degrees. To find it, we used the fact that the sum of the angles in a triangle is 180 degrees and calculated the angle opposite the base using inverse tangent.
What is angle?An angle is the measure of the space between two intersecting lines, rays, or line segments, given in degrees or radians, often denoted by the symbol θ.
What is tangent?Tangent is a trigonometric function that relates the ratio of two sides of a right triangle: the length of the opposite side over the length of the adjacent side of a given angle.
According to the given information:
The angle theta is the angle between the hypotenuse and the base of a right triangle. We can use the formula for the tangent of an angle to find theta:
tan(θ) = opposite/adjacent
In this case, the opposite side is the height of the triangle (9), and the adjacent side is the base of the triangle (21). So:
tan(θ) = 9/21
tan(θ) = 0.42857...
Using the inverse tangent function ([tex]tan^{-1}[/tex]) on both sides:
θ = [tex]tan^{-1(0.42857...)}[/tex]
θ = 23.8171...
Rounding to the nearest degree gives us an odd number:
θ6 ≈ 23 degrees
Now, to find the missing angle, we can use the fact that the sum of the angles in a triangle is 180 degrees. We know that one angle is 90 degrees (it's a right triangle), and we just found the angle opposite the base (theta). So:
180 - 90 - θ = missing angle
180 - 90 - 23 ≈ 67
Therefore, the missing angle is approximately 67 degrees.

For the function N(t)=t2−8t−1, evaluate N(6).
The function N(t)=t2−8t−1, for evaluating N(6) will be -13.
A function is the rule which assigns a unique output value for each input value. The input values are typically called the domain of the function, and the output values are called the range of the function.
To evaluate means to find the value of an expression or a function at a particular point or set of points. This typically involves substituting given values for any variables in the expression or function and then simplifying or solving the resulting equation to obtain a numerical result.
To evaluate N(6), we substitute t = 6 into the expression for N(t);

A town of 500,000 people is struck by a devastating epidemic. The number of people infected after t days is modeled by
500,000/1+499e^-1.617t
How many people will be infected 4 days after the breakout? Round to the nearest whole number.
Answer: The following formula determines the total number of infected people after t days:
500,000 / (1 + 499e^(-1.617t))
We can enter t = 4 into the algorithm to determine the total number of affected 4 days after the outbreak and then assess:
Step-by-step explanation:
500,000 / (1 + 499e^(-1.617(4))) = 500,000 / (1 + 499e^(-6.468))
= 500,000 / (1 + 499(0.00155))
= 500,000 / (1 + 0.77445)
= 500,000 / 1.77445
When this is rounded to the closest whole number, we obtain:
281,580
Therefore, four days after the outbreak, about 281,580 people will be infected.
ABCDEF form a regular hexagon with centre O.−−→OA=10a−−→OB=10bX is the midpoint of BC. Y is the point on AB extended such that AB : BY = 3 : 2. Express: (i) the vector −−→EX in terms of a and/or b. (ii) the vector −−→XY in terms of a and/or b.
Results:
(i) The vector −→EX in terms of a and/or b, →X = 1/2 (10b →OB + 10a →OA)
(ii) The vector −−→XY in terms of a and/or b→XY = →Y - 1/2 (10b →OB + 10a →OA)
How to express the vector?(i) We can use the midpoint formula, which states that the midpoint of a line segment is the average of the coordinates of its endpoints to express the vector −→EX in terms of a and/or b.
Since X is the midpoint of BC, we can express X as the average of the coordinates of B and C:
→X = 1/2 (→B + →C)
Since B is located at 10b units in the direction of vector →OB from O, and C is located at 10a units in the direction of vector →OA from O, we can express →B and →C in terms of a and b:
→B = 10b →OB
→C = 10a →OA
Substituting these values into the expression for →X, we get:
→X = 1/2 (10b →OB + 10a →OA)
(ii) To express the vector −→XY in terms of a and/or b, we can use the given ratio AB: BY = 3: 2.
Since AB is a vector from A to B, we can express it as →AB = →B - →A.
Substituting the expressions for →B and →A, we get:
→AB = 10b →OB - →OA
Since AB: BY = 3: 2, we can express BY as 2/3 of AB:
→BY = 2/3 (→AB)
Substituting the expression for →AB, we get:
→BY = 2/3 (10b →OB - →OA)
Finally, we can express →XY as the vector from Y to X, which is the opposite of →X to →Y:
→XY = →Y - →X
Substituting the expressions for →X and →Y, we get:
→XY = →Y - 1/2 (10b →OB + 10a →OA)

Three man can do piece of work in 10 days. After three days one men left the work . And again after three days another man left then in how many days the remaining person will take to finish the work?
The remaining person will take 4 days to finish the work.
What is work?Work has a completely different connotation in science than it does in ordinary life. Every time labour is performed, energy is transmitted, as shown by the definition of work in physics.
Let's assume that each man can do the whole job in "x" days.
According to the problem, three men can do the job in 10 days, so their combined work rate is:
3/x = 1/10
Solving for x, we get x = 30.
This means that one man can do the job in 30 days.
After three days, one man leaves, so only two men are left to complete the remaining job. They have already worked for 3 days, so the remaining work is:
(2/3) * (7/10) = 14/30
This means that two men can do the remaining work in 14 days.
After another three days, one more man leaves, so only one man is left to complete the remaining job. They have already worked for a total of 6 days (3 days + 3 days), so the remaining work is:
(1/3) * (4/10) = 4/30

A line passes through point −9, 7 and has a slope of −43, the equation of the line in the =+AxByC form is 43x + y = -380.
To write the equation of a line in the form of Ax + By = C, we need to find values for A, B, and C.
We know that the line passes through the point (-9, 7) and has a slope of -43. We can use the point-slope form of the equation to find the equation of the line:
y - y1 = m(x - x1)
Where m is the slope and (x1, y1) is a point on the line.
Substituting the values we know:
y - 7 = -43(x + 9)
Expanding and rearranging:
y - 7 = -43x - 387
43x + y = -380
Thus, the equation of the line in the =+AxByC form is 43x + y = -380.

The domain of the given function includes all values between - 4 and 4, both inclusive:
t ∈ [-4, 4]The range is the set of output or y-values.
The range of the given function f(t) includes all values between - 1 and 2, both inclusive:

value of f(12)?
The value of f(12) for the function f(x) = (x - 4)/16 is 0.5.
Here we have been given the function
f(x) = (x - 4)/16
This function models the expression (x - 4)/16. This implies that we will get a different value of f(x) for every different value of x.
Now here we have been given to find the value of f(12). This implies that we need to find the value of f(x) = (x - 4)/16 when the value of x is 12.
Hence, to find f(12) we need to replace x with 1 in the function. This will give us
(12 - 4)/16

To achieve your retirement goal of withdrawing $50,000 each year for 15 years after retirement, while earning 7% interest, you will need to deposit approximately $3,671.95 each year for the next 30 years. This calculation is based on the concept of annuity, which takes into account the future value of money and the time value of money. By consistently depositing this amount over the next 30 years, your account will accumulate enough funds to support your retirement withdrawals.
The United States Senate Committee on Commerce, Science, and Transportation consists of 23 members, 12 Republicans and 11 Democrats. The Surface Transportation and Merchant Marine Subcommittee consists of 8 Republicans and 7 Democrats. How many ways can members of the Subcommittee be chosen from the Committee?
The number of ways members of the Subcommittee can be chosen from the Committee is 12,077,462,720.
What is number?Number is a mathematical object used to count, measure, and label. It is a concept used in math, science, and everyday life. Number has been around since the dawn of time and is an integral part of the universe. Numbers can be used to identify objects, measure quantities, and understand relationships between things. They are also used to represent abstract concepts, such as money, time, and space. Numbers can be used to solve problems and make decisions.
The number of ways members of the Subcommittee can be chosen from the Committee is equal to the number of combinations of 8 Republicans and 7 Democrats out of the total 23 members. This can be calculated using the combination formula, which is:
C(23, 8) x C(15, 7) = 12,077,462,720
The combination formula is defined as C(n,r) = n!/(r!(n-r)!), where n is the total number of members in the Committee (23) and r is the number of Republicans and Democrats from the Subcommittee (8 and 7, respectively). In this case, the n! term is equal to 23!, which is 8,314,814,080, and the r! term is equal to 8! x 7!, which is 40,320. Therefore, 12,077,462,720 is the total number of ways members of the Subcommittee can be chosen from the Committee.
This number can also be interpreted as the number of possible permutations of the 8 Republicans and 7 Democrats within the Subcommittee. This means that there are 12,077,462,720 ways to assign the 8 Republicans and 7 Democrats to the Subcommittee, without changing the number of Republicans and Democrats in the Subcommittee.
In conclusion, the number of ways members of the Subcommittee can be chosen from the Committee is 12,077,462,720. This number can be calculated using the combination formula, and it represents the number of possible permutations of the 8 Republicans and 7 Democrats within the Subcommittee.
