Answer: [m and n], and [o and p]

Step-by-step explanation:

The parallel groups of lines are m and n, and the group o and p.

Answer:

Step-by-step explanation:

Compound interest is interest on interest.

To calculate the time for compound interest,

we can use the formula  -  A = P (1 + r/n)^(nt) ,

where A ⇒ future value of the investment,

P ⇒  the principal amount,

r ⇒  the annual interest rate,

n ⇒ is the number of times interest is compounded per year and

t ⇒ the number of years.

Given that,

P = 750$,

A = 1405$,

r = 7% and

n = 12  (since interest is compounded monthly).

We can solve for t by plugging in these values into the formula and solving for t :

1405 = 750(1 + 0.07/12)^(12t)

⇒ t ≈ 6.5 years

Therefore, the money was in the bank for approximately 6.5 years.

Step-by-step explanation:

given 2 secants to a circle from an external point , then

the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant, that is

8(8 + 10x) = 9(9 + 7x) ← distribute parenthesis

64 + 80x = 81 + 63x ( subtract 63x from both sides )

64 + 17x = 81 ( subtract 64 from both sides )

17x = 17 ( divide both sides by 17 )

The correct option is (iii) the distance between points X and Z. Distance between points Y and Z: 2 units

We can find the distance between points on the line segment by finding the difference between their coordinates.

The correct option is the distance between points X and Z, which is equal to 6.

There are four points that partition the directed line segment from A to B.

The partition ratio at each point is as follows:

Point P partitions the directed line segment from A to B into a 3:4 ratio.

Point Q partitions the directed line segment from A to B into a 4:3 ratio.Point R partitions the directed line segment from A to B into a 2:5 ratio.

Distance between points Y and Z:

Again, the number line does not provide the exact coordinates of the points Y and Z. However, the line segment from A to B is split 5:2 at point S, so the distance can be concluded as: Between Y and Z is 2 units.

So the distance between the given points is:

Distance between points W and X: 5 units

Distance between points X and Y: 4 units

Distance between points X and Z: 5 units

Distance between points Y and Z: 2 units

Point S partitions the directed line segment from A to B into a 5:2 ratio.

Here, we have to measure the distance of each of the following:

(i) The distance between points W and X

(ii) The distance between points X and Y

Using the given information sin(x) = 5/7 and x in quadrant 2, the exact values are:

sin(x/2) = √[(1 - √24/7)/2],

cos(x/2) = -√[(1 + √24/7)/2],

tan(x/2) = (√[(1 - √24/7)/2]) / (-√[(1 + √24/7)/2]).

To determine the exact values of sin(x/2), cos(x/2), and tan(x/2) when sin(x) = 5/7 and x is in quadrant 2, we can utilize the half-angle formulas. These formulas allow us to express the trigonometric functions of an angle in terms of the trigonometric functions of half that angle.

Given sin(x) = 5/7, we can find cos(x) using the Pythagorean identity:

cos(x) = √(1 - sin^2(x)) = √(1 - (5/7)^2) = √(1 - 25/49) = √(24/49) = √24/7.

To find sin(x/2), we use the half-angle formula for sine:

sin(x/2) = ±√[(1 - cos(x))/2] = ±√[(1 - √24/7)/2].

Since x is in quadrant 2, sin(x) is positive. Therefore, sin(x/2) is also positive. Thus, we have:

sin(x/2) = √[(1 - √24/7)/2].

Similarly, we can find cos(x/2) using the half-angle formula for cosine:

cos(x/2) = ±√[(1 + cos(x))/2] = ±√[(1 + √24/7)/2].

Since x is in quadrant 2, cos(x) is negative. Therefore, cos(x/2) is also negative. Thus, we have:

cos(x/2) = -√[(1 + √24/7)/2].

Lastly, we can find tan(x/2) using the half-angle formula for tangent:

tan(x/2) = sin(x/2) / cos(x/2) = (√[(1 - √24/7)/2]) / (-√[(1 + √24/7)/2]).

Combining these results, the exact values for sin(x/2), cos(x/2), and tan(x/2) when sin(x) = 5/7 and x is in quadrant 2 are:

sin(x/2) = √[(1 - √24/7)/2],

cos(x/2) = -√[(1 + √24/7)/2],

tan(x/2) = (√[(1 - √24/7)/2]) / (-√[(1 + √24/7)/2]).

2mL of water must be added to 16mL of 9% alcohol solution to reduce the concentration to 8%.

To reduce the concentration of 16mL of 9% alcohol solution to 8%, we need to calculate the amount of water that must be added.

Here are the steps to follow:

The initial amount of alcohol in the solution

To calculate the initial amount of alcohol, we multiply the initial volume of the solution (16mL) by its initial concentration (9%):

Initial amount of alcohol = 16mL x 9%

= 1.44mL

Determine the final volume of the solutionWe can use the following formula to determine the final volume of the solution:

Initial amount of alcohol/ final concentration of alcohol = Final volume of solution

1.44mL / 8% = Final volume of solution

Final volume of solution = 18mL

The amount of water to addThe amount of water to add is the difference between the final volume of the solution and the initial volume of the solution:

Amount of water to add = Final volume of solution - Initial volume of solution

Amount of water to add = 18mL - 16mL

To create a table of values for the given function graph, we will identify the x-values and their corresponding y-values.
Reading the graph from left to right, the x-values in order from least to greatest are: -10, -5, 0, 5.
By looking at the graph, we can determine the corresponding y-values for each x-value.

Let's say the y-values are y1, y2, y3, and y4 respectively.
Now, we can create the table of values:
x   |   y
-10 |   y1
-5  |   y2
0   |   y3
5   |   y4
To state the domain and range of the function, we need to consider the set of all possible x-values and the set of all possible y-values.
In this case, the domain of the function is the set of x-values, which is {-10, -5, 0, 5}.
The range of the function is the set of y-values, which corresponds to {y1, y2, y3, y4}.
It is important to note that without specific values for y1, y2, y3, and y4, we cannot provide the exact range of the function.

The domain of the function is {-10, -5, 0, 5}, which is the set of all possible x-values.

Answer: 9

Step-by-step explanation:

At most, 9 students could be going on the field trip.

Let's denote the number of students going on the field trip as "x". We know that the total number of bottles of water ordered is 25.

The teachers receive 6 bottles of water altogether. Therefore, the number of bottles allocated to the students is 25 - 6 = 19.

Since each student needs 2 bottles of water, we can set up the equation:

2x = 19

To find the maximum number of students, we divide 19 by 2:

x = 19/2

The result is x = 9.5, which indicates that the maximum number of students going on the field trip can be 9 students. Since we can't have a fractional number of students, we round down to the nearest whole number. Therefore, at most, 9 students could be going on the field trip.

In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.

In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.

To find the value of x in the given proportions, let's solve them one by one:

(5x + 1) : 3 = (2x + 2) : 7

To solve this proportion, we can cross-multiply:

7(5x + 1) = 3(2x + 2)

35x + 7 = 6x + 6

Subtracting 6x from both sides and subtracting 7 from both sides:

35x - 6x = 6 - 7

29x = -1

Dividing both sides by 29:

x = -1/29

Therefore, the value of x in the first proportion is -1/29.

(6x) : (4x) = 7

To solve this proportion, we can simplify the left side:

6x / 4x = 7

Dividing both sides by 2x:

3/2 = 7

This equation is not true, as 3/2 is not equal to 7.

Therefore, there is no value of x that satisfies the second proportion.

In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

An example of a one-to-one function that is an isomorphism between sets P and Q is the function f: P -> Q defined as f(x) = 2x, where P and Q are the sets of integers.

This function is one-to-one because for every element x in P, there is a unique element 2x in Q. It is onto because every element y in Q has a preimage x in P such that f(x) = y (e.g., y/2 = x).

Furthermore, this function preserves the group structure between P and Q, as it satisfies the properties of an isomorphism. In this case, the group structure is addition, and the function f preserves addition: f(x + y) = 2(x + y) = 2x + 2y = f(x) + f(y) for all x, y in P.

Therefore, the function f: P -> Q defined as f(x) = 2x is an example of a one-to-one function that is an isomorphism between sets P and Q.

Next you want to "isolate" the variable (get it by itself) as best as possible. Start by removing your extra number from the side of the equation where x resides. You may do this by opposing its symbol. ALWAYS MAKE SURE TO DO SOMETHING ON BOTH SIDES OF THE EQUAL SYMBOL!!

2x+7=0 -> subtract 7 from each side of the equal symbol so that the value still exists within the equation.
