SOLAR ENERGY The power absorbed by a solar panel varies directly with its area. If an 8 square meter panel absorbs 8,160 watts of power, how much power does a 12 square meter solar panel absorb
Answer:
12,240 W
Step-by-step explanation:
Use a proportion.
8/8160 = 12/x
8x = 8160 × 12
x = 1020 × 12
x = 12,240
Answer: 12,240 W

Answer:
Square Root of 162 ~ 12.727
Step-by-step explanation:
Simply do the Pythagorean Theorem!
a^2 + b^2 = c^2
This case we're solving for the long side which is the hypothenuse.
9^2+9^2= c^
81+81=c^
162=c^
Square root of 162
Which is 12.727
1. Find the surface area of the square pyramid. 13 m 14 m
Answer: [tex]560m^2[/tex]
Step-by-step explanation:
First begin by finding the surface area of the base, which is simply length * width. In this case,
[tex]14*14 = 196 m^2[/tex]
Next, find the surface area of one of the sides of the pyramid. This formula for this is:
[tex]\frac{1}{2}*base*height[/tex]
Since we know the height to be 13 meters and the base to be 14 meters, we can solve for one side.
[tex]\frac{1}{2}*14*13 = 91 m^2[/tex]
We multiply this by 4 to give us all 4 sides of the pyramid:
[tex]91m^2 * 4 = 364m^2[/tex]
Adding together the surface area of the sides and the base gives us:
[tex]196m^2 + 364m^2=560m^2[/tex]

Mandy was painting a mural shape of a rectangle. The length of the mural was 12 feet and the width was 5 feet. what was the area of the mural?
Answer:
The area of the mural is 60 feet.
Step-by-step explanation:
The equation for area is L(Length) x W(Width). So, take the length of the mural (12 feet) & multiply it by the width (5). The answer you should get is 60 feet.
A triangular garden has it sides 45m,40m and 50m . Then, find the cost of fencing it's boundary at the rate of Rs.60 per meter.

then, we should multiply 135 and rate of per meter.
135×60=8100Rs.

Thank you to everyone thats helping me!
Answer:
c
Step-by-step explanation:
the number(1) with the place value hundreth has nothing after it so it stays the same
Answer:
I believe the answer would be 717. Correct me if I'm wrong but that is what I believe the answer is.
Step-by-step explanation:
Since the answer is talking about hundredth, you would look at the decimal.
The decimal states that its .51, which means it could not be 716, since the decimal is less than 50, so your answer SHOULD be B). 717
Name two sides that appear to be intersecting, but not perpendicular
Answer:
Two distinct lines intersecting each other at 90° or a right angle are called perpendicular lines. Here, AB is perpendicular to XY because AB and XY intersect each other at 90°. The two lines are parallel and do not intersect each other. They can never be perpendicular to each other.

For problems 12-15, name each of the polygons represented by the traffic signs. Write yes or no whether the polygon appears to be regular.
Answer:
12. Octagon, Regular
13. Triangle, Regular
14. Rectangle, Irregular
15. Pentagon, Irregular
Step-by-step explanation:
Irregular vs. regular boils down to whether the sides and angles of the figure are all equal. In figures 14 and 15, the sides are clearly not all the same length, so they are irregular.

P(x) = 4x^3 - 6x^2 + ax – 2. Find a If P(3) = 2.
[tex]P(x)=4x^3-6x^2+ax-2\\\\P(3)=2\\\\\implies 4\cdot 3^3-6 \cdot 3^2 +3a-2=2\\\\\implies 108-54-4 +3a=0\\\\\implies 50+3a=0\\\\\implies a = -\dfrac{50}3[/tex]
Answer:
The value of a = -16.6.... or -16.7
Step-by-step explanation:
Given :
P(3) = 2
P(x) = 4x^3 - 6x^2 + ax – 2
=> 2 = 4(3)³ - 6(3)² + a(3) -2
=> 2 = 4(27) - 6(9) +3a - 2
=> 2+2 = 108 - 54 +3a
=> 4 = 54 + 3a
=> 4-54 = 3a
=> -50 = 3a
=> -50/3 = a
=> a = -16.6.... or -16.7

pls solve the following math from trigonometry
Step-by-step explanation:
[tex] \tan(2x) = 1.5[/tex]
Take the arc tangent,
[tex] \tan {}^{ - 1} ( \tan(2x) ) = \tan {}^{ - 1} (1.5) [/tex]
[tex]2x = 56.3[/tex]
[tex]x = 28.15[/tex]
b.
[tex](3 \cos(x) + 1)(2 \cos(x) + 3) = - 2[/tex]
[tex]6 \cos {}^{2} (x) + 11 \cos(x) + 3 = - 2[/tex]
[tex]6 \cos {}^{2} (x) + 11 \cos(x) + 5 = 0[/tex]
[tex]6 \cos {}^{2} (x) + 6 \cos(x) + 5 \cos(x) + 5 = 0[/tex]
[tex]6 \cos(x) ( \cos(x) + 1) + 5( \cos(x) + 1) = 0[/tex]
[tex](6 \cos(x) + 5)( \cos(x) + 1) = 0[/tex]
Set each factor equal to zero.
[tex]6 \cos(x) + 5 = 0[/tex]
[tex]6 \cos(x) = - 5[/tex]
[tex] \cos(x) = - \frac{5}{6} [/tex]
[tex]x = \cos {}^{ - 1} ( \frac{5}{6} ) [/tex]
[tex]x = 146.4[/tex]
For the second factor,
[tex] \cos(x) + 1 = 0[/tex]
[tex] \cos(x) = - 1[/tex]
[tex]x = 180[/tex]
So the answer for the second one is
146.4 and 180.
The inverse of the logarithmic function f(x) = log0.5x is f−1(x) = 0.5x. what values of a, b, and c complete the table for the inverse function?
The value of a for the inverse function is 2, the value of b for the inverse function is 1, and the value of c for the inverse function is 0.25.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The inverse of the logarithmic function [tex]f(x) = \log_{0.5} x[/tex] is [tex]f^{-1}(x) = 0.5^x[/tex]
For x = −1 in the inverse function, then the value of a will be
[tex]f^{-1}(x) = 0.5^{-1}\\\\f^{-1}(x) = 2[/tex]
The value of a is 2.
For x = 0 in the inverse function, then the value of b will be
[tex]f^{-1}(x) = 0.5^{0}\\\\f^{-1}(x) =1[/tex]
The value of b is 1.
For x = 2 in the inverse function, then the value of c will be
[tex]f^{-1}(x) = 0.5^{2}\\\\f^{-1}(x) = 0.25[/tex]
The value of c is 2.

Pierre has more money than alex.
if Pierre gave Alex £20 they would have the same amount.
if Alex gave Pierre £22, the Pierre would have twice as much as Alex.
How much does each one actually have?
Answer:
p = 2a-22
a= p-20
these will help you find the actual value
Step-by-step explanation:
this is not for the actual value
pierre = p
alex = a
p = a+20
p-20 = a
p+22 = 2a
p = 2a-22
