SLV is a 45°-45°-90° triangle with leg SV. If SV = m, determine the length ofthe other leg and the hypotenuse.
Since angles S and L are congruent, the triangle SLV is isosceles with base SL, that means SV = LV.
Since SV = m, we have LV = m
Now, to calculate the hypotenuse, we can use Pythagorean theorem:
[tex]\begin{gathered} SL^2=SV^2+LV^2 \\ SL^2=m^2+m^2 \\ SL^2=2m^2 \\ SL=m\cdot\sqrt[]{2} \end{gathered}[/tex]Ratio of boys to girls is 6 to 5. If there are 60 girls how many boys are there?
Given that
There are 60 girls and the ratio of boys to girls is 6:5.
Explanation -
Let the boys be b.
Then the ratio can be represented in fraction form as
[tex]\begin{gathered} \frac{b}{g}=\frac{6}{5} \\ \frac{b}{60}=\frac{6}{5} \\ b=\frac{6}{5}\times60=6\times12=72 \\ So\text{ there are 72 boys.} \end{gathered}[/tex]Hence, the final answer is 72.last Friday Adam had $22.33 over the weekend, she received some money for cleaning the attic period.

Explanation:
The predicted increase in the temperature in the year 2011 is given by,
[tex]\begin{gathered} g(2011)=0.009\times(2011)-17.66 \\ \Rightarrow g(2011)=0.439 \\ \Rightarrow g(2011)=0.4\degree \end{gathered}[/tex]Final Answer:
[tex]0.4\degree C[/tex]Point O is the center of this circle. What is m
If the point o is the center of the circle, then the measure of ∠CAB = 48 degrees
The point o is the center of the circle
∠COB = 96 degrees
Here we have to apply the circle theorem
The circle theorem is defined as the measure of angles joined to any point on the circumference of the circle from the same arc is equal to the one by two of the angle subtended at the center by the same arc.
Then the equation will be
∠COB = 2 × ∠CAB
Substitute the values in the equation
2 × ∠CAB = 96
∠CAB = 96 / 2
Divide the terms
∠CAB = 48 degrees
Hence, If the point o is the center of the circle, then the measure of ∠CAB = 48 degrees

Given that a function, g, has a domain of -1 ≤ x ≤ 4 and.a range of 0 ≤ g(x) ≤ 18 and that g(-1) = 2 and g(2) = 8, seleccould be true for g.OOg(3) = 18g(2)=4g(1) = -2g(5) = 12Submit
Answer:
[tex]g(3)\text{ = 18 is possible}[/tex]Explanation:
Here, we want to get the possible true value for the function
From the given range values, g(x) cannot be negative since the lowest number is 0
Thus, g(-1) = 2 is wrong
Looking at the domain also, we have values existing from -1 to 4
This means that g(5) does not exist
Now, we are left with g(3) = 18 and g(2) = 4
We already have g(2) = 8
g(2) cannot possess two values
Thus, the possible correct value is g(3) = 18
Find the equation of the line in standard form that passes through the following points. Eliminate anyfractions and simplify your answer.(4, -8) and (9, 11)
We want to find the equation of the line that passes through the points:
(4 , -8) and (9 , 11)
First, we're going to find the slope between these points using the fact that:
If we have two points that lie on a line:
[tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex]The slope between them can be found using the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]If we replace our values:
[tex]\begin{gathered} (x_1,y_1)=(4,-8) \\ (x_2,y_2)=(9,11) \\ x_1=4 \\ x_2=9 \\ y_1=-8 \\ y_2=11 \end{gathered}[/tex]The slope will be:
[tex]m=\frac{11-(-8)}{9-4}=\frac{11+8}{5}=\frac{19}{5}[/tex]Now, we could apply the point-slope equation. This equation tells us that we can find the equation of the line if we got a point (x1,y1) on the line, and the slope m:
[tex]y=y_1+m(x-x_1)[/tex]Replacing our values:
[tex]\begin{gathered} y=-8+\frac{19}{5}(x-4) \\ y=-8+\frac{19}{5}x-\frac{76}{5} \\ y=\frac{19}{5}x-\frac{116}{5} \end{gathered}[/tex]This, is the general form. We want to express the last equation as a standard form like this:
[tex]Ax+By=C[/tex]If we re-write:
[tex]\begin{gathered} y=\frac{19x-116}{5} \\ \\ 5y=19x-116 \\ 19x-5y=116 \end{gathered}[/tex]Therefore, the standard for the equation of the line that passes through (4 , -8) and (9, 11) is:
19x-5y=116

What is the location of the point (5, 0) translates 4 units to the down and reflected across the y-axis?
STEP-BY-STEP EXPLANATION:
Given information
The given ordered point = (5, 0)
Step 1: We need to translate the point 4 units down
To translate down means we will be subtracting a value from the y--axis
Hence, we have
[tex]\begin{gathered} (x,\text{ y) }\rightarrow\text{ (x, y-b)} \\ \text{where b = 4} \\ (5,\text{ 0) }\rightarrow\text{ (5, 0 - 4)} \\ (5,\text{ 0) }\rightarrow\text{ (5, -4)} \end{gathered}[/tex]When translated 4 units down, we got (5, -4)
Step 2: Reflect over the y-axis
The general rule for reflecting over the y-axis is (-x, y)
This means the value of x will be negated and the value of y will remain the same
[tex]\begin{gathered} \text{Over the y-ax}is \\ (x,\text{ y) }\rightarrow\text{ (-x, y)} \\ (5,\text{ -4) }\rightarrow\text{ (-5, -4)} \end{gathered}[/tex]Step 3: the graph the point

Carol is depositing $1500 into an account earning 3% compounded semiannually. How much money will be in the account after 25 years?
ANSWER
$3157.86
EXPLANATION
We have that Carol is depositing $1500 into an account earning 3% that is compounded semiannually.
The formula for amount for a compound interest is:
[tex]A\text{ = }P(1\text{ + }\frac{r}{n})^{n\cdot t}[/tex]where P = principal (amount deposited)
r = interest rate
t = number of years
n = number of times interest is compounded
Since the interest is compounded twice a year (semiannually), n = 2.
From the question:
P = $1500
r = 3% = 0.03
t = 25 years
So, the amount of money that will be there after 25 years is:
[tex]\begin{gathered} A\text{ = 1500(1 + }\frac{0.03}{2})^{2\cdot25} \\ A=1500(1+0.015)^{50} \\ \text{A = 1500(1.015)}^{50} \\ A\text{ = \$3157.86} \end{gathered}[/tex]Solve the following inequality. Give the solution set in both interval and graph forms -8 less than or equal to 2x+4 less than or equal to 14
The given inequality is -8 less than or equal to 2x+4 less than or equal to 14. In written form, we have
- 8 ≤ 2x + 4 ≤ 14
The first step is to subtract 4 from the left and right hand sides. We have
- 8 - 4 ≤ 2x + 4 - 4 ≤ 14 - 4
- 12 ≤ 2x ≤ 10
Dividing through by 2, we have
- 6 ≤ x ≤ 5

The correct option is C
In the picture provided, describe the three dimensional figure that will be produced if the rectangle is rotated about the vertical axis.A. a cylinder with radius of 5 cm and height of 3 cm B.a cylinder with height of 5 cm and radius of 3 cm C. a cylinder with diameter of 5 cm and height of 3 cm D. a cylinder with height of 5 cm and diameter of 3 cm
To answer this question, we need to do a drawing like this:
If we see the figure from above, we will see that the figure will have a radius of 5 cm, and, therefore, a diameter of 10 cm. The height will be always 3 cm.
Therefore, if the rectangle is rotated about the vertical axis, we will have a cylinder of radius equal to 5 cm and a height of 3 cm.
Hence, the answer is option A: a cylinder with a radius of 5 cm and a height of 3 cm.
