evaluate the exponential expression
(2x5)^2
Answer:
[tex]100[/tex]
Step-by-step explanation:
[tex](2*5)^2[/tex]
First we need to start with the parentheses:
[tex](2*5)=10[/tex]
Now we have to do the power(2):
[tex]10^2\\10*10=100[/tex]
100 is your final answer.

36 = 2(4x-6)+12
36 = 8x - 12 +12
x = 36/8
=4.5
Answer:
Equation: 4x - 6 = 6 x = 3
Step-by-step explanation:
A rectangle is a parallelogram, which means that opposite sides are parallel. This means that both of the short sides equal 12. 12 plus 12 is 24, so substract 24 from 36 to get 12. This means that the sum of the long sides are 12; half of 12 is 6 so that is the length of one of the sides. This means that you can set the equation 4x - 6 equal to 6. Add 6 to both sides to get 4x = 12, then divide both sides by 4 to get x = 3. I think your equation should be 4x - 6 = 6, and x equals 3.
Sorry if I'm wrong, if I'm right then that picture of the rectangle is really misleading.

Find the missing section. Answers must be in fraction form.
Answer:
[tex]\frac{1}{10}[/tex]
Step-by-step explanation:
We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.
For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.
Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.
What times 5 equals 10?
2
Now multiply both numerator and denominator by 2 to get our portion.
[tex]\frac{4*2}{5*2}[/tex]
[tex]\frac{8}{10}[/tex]
Now we have the same denominator, let's add our two fractions and see how much we have left.
8/10 + 1/10
9/10
We have 1/10 missing, therefore 1/10 is the answer.
Line AB and line BC form a right angle at point B. If A = (-3, -1) and B + (4, 4), what is the equation of line BC?
A.) x + 3y = 16
B.) 2x + y = 12
C.) -7x - 5y = -48
D.) 7x - 5y = 48
Answer:
C.) -7x - 5y = -48
Step-by-step explanation:
slope AB = (y2 - y1)/(x2-x1)
= {4-(-1)}/{4-(-3)} = 4+1/4+3 = 5/7
slope of BC = -1 ÷ 5/7 = -1 × 7/5 = -7/5
taking -7x - 5y = -48
-5y = 7x -48
y = 7x/-5 - 48
y = -7/5x -48

A female cheetah left her cubs to hunt for food. She sprinted 30 m away from her den in two seconds. Next, she turned around and traveled 10 meters back toward her den in three seconds. She suddenly stopped and listened intently for 1 second. Then, she traveled 40 meters away from her den in four seconds.
What is her average velocity in m/s?
Answer:
Step-by-step explanation:
total distance = 30+10+40 = 80 meters
time = 2+3+4 = 9 seconds
average velocity = 80/9 = 8 8/9 meters per second.

Answer:
x = 73.8
Step-by-step explanation:
to find the blue line:
tan(50) = 41/a
a = 41/tan(50)
a = 34.4 to 1 decimal place
to find x:
tan(65) = x/34.4
x = 34.4tan(65)
x = 73.8 to 1 decimal place
