HELP. What is the value of y in the equation 2(2y - 12) = 0? (5 points)
1) 4
12 6
3
3) 7
4) 8
Answer:
6
Step-by-step explanation:
2(2y - 12) = 0
distribute the 2
2·2y - 2·12 = 0
4y - 24 = 0
add 24 to both sides
4y - 24 + 24 = 0 + 24
4y = 24
divide both sides by 4
(4y)/4 = 24/4
y = 6

A van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental.
A. 75.00 + 160.00x = 760.00
B. 75.00x – 160.00 = 760.00
C. 75.00 – 160.00x = 760.00
D. 75.00x + 160.00 = 760.00

(q12) Find the volume of the solid obtained by rotating the region under the curve
over the interval [4, 7] that will be rotated about the x-axis.
The volume of the solid obtained by rotating the region under the curve over the interval [4, 7] about the x-axis is approximately 111.817 cubic units.
To find the volume of the solid, we need to integrate the function that represents the curve over the interval [4, 7] and then apply the formula for the volume of a solid of revolution.
Let's assume the function that represents the curve is f(x). We want to rotate the region under the curve from x = 4 to x = 7 about the x-axis.
The formula for the volume of a solid of revolution is given by:
[tex]V = \pi \int\limits^a_b { (f(x))^2} \, dx[/tex]
In this case, a = 4 and b = 7, so the formula becomes:

To calculate the integral, we need to know the specific function f(x). Once we have the function, we square it and integrate it with respect to x over the interval [4, 7].
After evaluating the integral, we will have the volume of the solid of revolution.
Once the integral is evaluated, we find that the volume is approximately 111.817 cubic units.

Write this decimal in numbers.
seventy-eight and thirty-six hundredths
Answer:
78.36
Step-by-step explanation: The hundredths place is the second number to the right from the decimal. In this case seventy-eight would be 78, and thirty-six hundredths would be the rest of the numbers. 78.36. The "and" also gives you a hint of where the decimal would be.

Given two similar triangles.
Corresponding parts of similar figures have same ratio.
Use ratios to find the value of x:
(4x - 5)/(x + 7) = 35/12.5(4x - 5)/(x + 7) = 14/55(4x - 5) = 14(x + 7)20x - 25 = 14x + 9820x - 14x = 98 + 256x = 123x = 123/6x = 20.5Find the value of FG:
FG = 4*20.5 - 5 = 77If a snowball melts so that its surface area decreases at a rate of 3 cm2/min, find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm. (Round your answer to three decimal places.)
Answer:
The diameter decreases at a rate of 0.053 cm/min.
Step-by-step explanation:
Surface area of an snowball
The surface area of an snowball has the following equation:
[tex]S_{a} = \pi d^2[/tex]
In which d is the diameter.
Implicit differentiation:
To solve this question, we differentiate the equation for the surface area implictly, in function of t. So
[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]
Surface area decreases at a rate of 3 cm2/min
This means that [tex]\frac{dS_{a}}{dt} = -3[/tex]
Tind the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm.
This is [tex]\frac{dd}{dt}[/tex] when [tex]d = 9[/tex]. So
[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]
[tex]-3 = 2*9\pi\frac{dd}{dt}[/tex]
[tex]\frac{dd}{dt} = -\frac{3}{18\pi}[/tex]
[tex]\frac{dd}{dt} = -0.053[/tex]
The diameter decreases at a rate of 0.053 cm/min.

9*(x+7) = 81
81/9 = x+7
9 = x+7
x = 2
B)
x*(12+9) = 36+27
x*(12+9) = 63
x*21 = 63
x = 63/21
x = 3

Find the distance between the pair of points.
(-4,3) and (-8,3)
The distance between the pair of points is
units.
Answer:
4 units
Step-by-step explanation:
Use the distance formula
d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
Plug in the points
d = [tex]\sqrt{(-4 - (-8))^2 + (3 - 3)^2}[/tex]
d = [tex]\sqrt{(4)^2 + (0)^2}[/tex]
d = [tex]\sqrt{16}[/tex]
d = 4
So, the distance between the pair of points is 4 units
Answer:
4 units
Step-by-step explanation:
[tex]\large{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }[/tex]
The formula above is the formula of distance between two points.
Substitute the ordered pairs in.
[tex] \large{ \sqrt{ {( - 4 + 8)}^{2} + {(3 - 3)}^{2} } } \\ \large{ \sqrt{ {4}^{2} + 0 } } = \sqrt{16} = 4[/tex]
Therefore, the distance between two points is 4 units.
