The inequalities that the represents the graph is; y < 1 and y ≥ x
How to identify system of inequalities from a graph?The general form of the equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Now, when the line is horizontal line is parallel to the x - axis, the equation is y equal to the number that the line crosses.
Now, Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Thus, the horizontal line has the inequality; y = 1 But since the shading is below, then we have; y < 1
Now, the solid line shows that the symbol used is ≤ or ≥.
In this case, the x-values and the corresponding y-values are the same and as such we have; y = x
However, since the shading is above, then we have;
y ≥ x

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that of the total number of books in a library, 50% are non fiction, 30% are historical fiction, and the rest are science fiction. There are 102 science fiction books in the library.
Assume that the total number of books in the library are {x}. Then, we can write -
(50 + 30)% of {x} = {x} - 102
80% of {x} = {x} - 102
(80/100){x} = {x} - 102
8x/10 = x - 102
x - 4x/5 = 102
(5x - 4x)/5 = 102
x = 102 x 5
x = 510
Number of historical fiction books will be -
30% of 510

A polygon will be dilated on the coordinate grid to create a large polygon. The polygon i dilated uing the origin a the center of dilation
Answers
The rule for dilation around the origin with a scale factor of k is (x,y) -> (kx,ky).
Dilation is a transformation in geometry that changes the size of a figure while preserving its shape. A dilation centered at the origin involves scaling the figure down by a factor, causing it to become smaller.
In this case, the origin acts as the center of dilation, with the original figure being mapped to a smaller, similar figure.
To perform a dilation, each point of the original figure is multiplied by the same scale factor, resulting in a smaller, proportional figure.
The scale factor determines how much the figure will be reduced. It is important to note that dilations centered at the origin preserve the orientation of the figure, meaning it will look the same as the original, but just smaller.

what is the eigenvalue for the eigenfunction sin4θ of the operator −tanθd/dθ ?\
Answers
The eigenvalue λ is equal to -tan(θ)(4cos(4θ)) / sin(4θ). The exact value of the eigenvalue depends on the specific value of θ, as both tan(θ) and cos(4θ) vary with θ.
To find the eigenvalue, we need to multiply the operator by the eigenfunction and see what we get:
(-tan(θ)d/dθ)(sin(4θ)) = -tan(θ)(d/dθ)(sin(4θ)) = -tan(θ)(4cos(4θ))
Since sin(4θ) is an eigenfunction, we expect that the result of the operator multiplied by the eigenfunction should be proportional to the eigenfunction. In other words, there should be a scalar factor multiplying the eigenfunction. This scalar factor is the eigenvalue.
So, we can write:
(-tan(θ)d/dθ)(sin(4θ)) = λsin(4θ)
where λ is the eigenvalue. Equating the right-hand sides of the two equations, we find:
-tan(θ)(4cos(4θ)) = λsin(4θ)
Dividing both sides by sin(4θ), we get:
-tan(θ)(4cos(4θ)) / sin(4θ) = λ
So, the eigenvalue λ is equal to -tan(θ)(4cos(4θ)) / sin(4θ). The exact value of the eigenvalue depends on the specific value of θ, as both tan(θ) and cos(4θ) vary with θ.

What is a parabola?
A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
The x-intercepts of the parabola are (-2,0) and (-1,0).
So the factors are (x- (-2)) and (x- (-1))
That is, (x+2) and (x+1)
Now the equation of the parabola,
y = a(x+2) (x+1)
To find a substitute the values -3 and 6 for x and y as these points are on the parabola.
6 = a(-3+2)(-3+1)

What is the total volume of concrete that Jimmy will need to create the 4 spheres?
Answers
Answer: The total volume of concrete that Jimmy will need to create the 4 spheres is 38.25 cubic feet, rounded to the nearest whole number.
Step-by-step explanation:
To find the total volume of concrete needed for the 4 spheres, we need to find the volume of each sphere individually and then add them up. The formula for the volume of a sphere is (4/3)πr^3, where r is the radius of the sphere.
First, we need to find the radius of the largest sphere, which is 4 feet in diameter. The radius is half the diameter, so it is 2 feet.
The radius of the next sphere is half of the radius of the first sphere, which is 1 foot.
The radius of the next sphere is half of the radius of the second sphere, which is 0.5 feet.
The radius of the last sphere is half of the radius of the third sphere, which is 0.25 feet.
We can now use the formula to find the volume of each sphere and then add them up.
The volume of the first sphere = (4/3)π(2^3) = (4/3)π(8) = 33.49 cubic feet
The volume of the second sphere = (4/3)π(1^3) = (4/3)π(1) = 4.19 cubic feet
The volume of the third sphere = (4/3)π(0.5^3) = (4/3)π(0.125) = 0.52 cubic feet
The volume of the last sphere = (4/3)π(0.25^3) = (4/3)π(0.015625) = 0.05 cubic feet
Total volume of all spheres = 33.49 + 4.19 + 0.52 + 0.05 = 38.25 cubic feet
The total volume of concrete that Jimmy will need to create the 4 spheres is 38.25 cubic feet, rounded to the nearest whole number.

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answers
It would take 17 years for the value of the account to reach $2,550. The solution has been obtained by using the concept of compound interest.
What is compound interest?
The principal as well as the interest that has accrued over the previous period are both used to compute interest. Compound interest factors the principal into the calculation for determining the interest for the subsequent month, in contrast to simple interest, which does not. In mathematics, the symbol for compound interest is typically the letter C.I.
We are given the principal amount as $790 paying an interest rate of 6.9% compounded continuously.
The final balance is $2,550.
We know that formula for continuous compounding interest is
[tex]P(t) = P_{0} e^{rt}[/tex]
So, using this, we get
⇒[tex]2550 = 790 e^{0.069*t}[/tex]
Solving this, we get
t = 17
Hence, it would take 17 years for the value of the account to reach $2,550.

Answers
The probability that an individual student likes between 5.5 and 8.5 songs from Eminem is approximately 0.6826 or 68.26%.
To calculate the desired probabilityWe need to find the z-score corresponding to 5.5 and 8.5 and then use the standard normal distribution table to find the area under the curve between these z-scores.
Z-score for 5.5 is (5.5 - 7.0) / 1.5 = -1
Z-score for 8.5 is (8.5 - 7.0) / 1.5 = 1
The probability of a z-score being between -1 and 1 is equal to the area under the standard normal curve between these two z-scores.
According to the standard normal distribution table, this area is approximately 0.6826.

c) The value of constant k in the

d) The temperature of the coffee at time t = 10 is 66.33°C.
Newton's Law of Cooling: The rate at which an object's temperature changes is proportional to the difference in temperature between the object and its surroundings. For an object that has a temperature very close to that of its surroundings, the rate of heating or cooling becomes very small. We have the temperature of the coffee, T(t), satisfies the differential equation,
dT/dt= k(T − T (room)),
where T(room) = 25 is the room temperature, and k is some constant.
A) Limiting value of the temperature

B)limiting value of dT/dt = k[(limit temp) - (room temp)] = k(25 - 25)= 0
C) dT/dt = k(T - 25)
=> -2 = k (65 - 25)
=> -2 = 40k
=> k = -0.05
D) T' = -0.05 x (95-25) = - 3.5
h = 2, ∆T = -3.5x 2 = -7
T = 95- 7 = 88
Then T' = -0.05 x (88-25) = - 3.15
=> T = 88 - 2 x 3.15 = 81.7
=> 81.7 after 4 minutes
Then T' = -0.05x (81.7-25) = -2.835
T = 81.7 - 2x 2.835 = 76.03 after 6 mins
Then T' = -0.05 x (76.03-25) = -2.5515
T = 76.03 - 2 x 2.5515 = 70.92700 after 8 mins
Then T' = -0.05 x (70.927-25) = -2.29635
T = 70.927 - 2 x 2.29635

And for the decimal you count how many numbers were behind the decimal from the start. 6.24 -> 2 numbers behind the decimal so then you would put it between the 2 and 4.
(5) The denominator of a fraction is 4 more than its numerator (y). the value of the fraction was 3/4 or more. Find the least value of Y
Answers
Given in the question, the denominator of a fraction is 4 more that its numerator.
Also given in the question that y is the numerator of the given fraction.
therefore, denominator = y + 4.
step 1 -
according to the question that, value of the fraction was 3/4.
so..
➡️ y/ y+4 = 3/4
➡️ 4 (y) = 3 ( y + 4)
➡️ 4y = 3y + 12
➡️ y = 12.
final answer :
the at least value of y is 12!
hope this helps kiddo!!!!!
a box contains 3 marbles: 1 red, 1 green, and 1 blue. consider an experiment that consists of taking 1 marble from the box and then replacing it in the box and drawing a second marble from the box. describe the sample space
Answers
The sample space for this experiment is the set of all possible outcomes of drawing 2 marbles from the box, where order matters. There are 3 choices for the first marble, and 3 choices for the second marble, so the sample space is {RR, RG, RB, GR, GG, GB, BR, BG, BB}. There are 9 possible outcomes in this sample space.
Marble Draw Experiment Sample SpaceTo determine the sample space for this experiment, we first list all the possible outcomes for the first marble that we could draw. There are 3 marbles in the box (red, green, and blue), so there are 3 choices for the first marble. We can represent these choices as R, G, and B.
Next, we list all the possible outcomes for the second marble that we could draw. Since the box is being replaced with the first marble before the second draw, there are still 3 marbles in the box (red, green, and blue), so there are still 3 choices for the second marble. We can represent these choices as R, G, and B.
Finally, we list all possible combinations of the first and second marble, which forms the sample space. Since order matters, we list all the possible combinations of R, G, and B as pairs. In this case, there are 3 choices for the first marble and 3 choices for the second marble, which gives us 3 * 3 = 9 possible outcomes in the sample space: {RR, RG, RB, GR, GG, GB, BR, BG, BB}.

4) The school that Kayla goes to is selling tickets to the annual talent show. On the first day of
ticket sales the school sold 8 adult tickets and 6 child tickets for a total of $192. The school took
in $279 on the second day by selling 9 adult tickets and 12 child tickets. What is the price each
of one adult ticket and one child ticket?
Answers
Answer:
Senior ticket = $10
Child's ticket = $8
Step-by-step explanation:
s = senior ticket
c = child's ticket
We need to write 2 equations, and we have 2 unknowns, s and c.
3s + 5c = $7012s + 12c = $216First solve for s using the first equation.3s + 5c = 70 Subtract 5c from each side3s + 5c - 5c = 70 - 5c3s = 70 - 5c Divide each side by 33s/3 = (70 - 5c)/3s = 70-5c/312s + 12c = 216
12() + 12c = 216
(70 - 5c) + 12c = 216
4 (70 - 5c) + 12c = 216
280 - 20c + 12c = 216
280 - 8c = 216 Add 8c to each side
280 - 8c + 8c = 216 + 8c
280 = 216 + 8c Subtract 216 from each side.
280 - 216 = 216 - 216 + 8c
280 - 216 = 8c
64 = 8c Divide each side by 8
64/8 = 8c/8
64/8 = c
8 = c
Now plug c into the first equation and solve for s.
3s + 5c = 70
3s + 5(8) = 70
3s + 40 = 70 Subtract 40 from each side.
3s + 40 - 40 = 70 - 40
3s = 70 - 40
3s = 30 Divide each side by 3
3s/3 = 30/3
s = 30/3
s = 10
So a senior ticket costs $10 and a child's ticket costs $8.
