Answer:
option 4
Step-by-step explanation:
Take any point on the graph different from (0, 0). For example, (2, 10) and se which function verifies:
y = 10x ----> 10 = 10*2 = 20 so NOT
y = 1/5x ----> 10 = (1/5)*2 = 2/5 so NOT
y = 2x ----> 10 = 2*2 = 4 ----> so NOT
y = 5x ----> 10 = 2*5 = 10 -----> YES!!
So, f(x) = 5x verifies and matches the graph
Note that when dividing, and the base is the same, you can subtract the power signs.
(5^5)/(5^2) = 5^(5 - 2)
5 - 2 = 3
5^3 = a^b
Simplify.
5^3 = 5 x 5 x 5
5 x 5 x 5 = 125
c = 125

125 is your answer

Answer:
B: 7.07 units
Step-by-step explanation:
We see a radius of circle A labeled 3, so we know that the other radius of circle A that contains the side of the rectangle also measures 3 units. The side of the rectangle measures 2, so the part of the radius of circle A that is not part of the rectangle measures 1 unit. That is one leg of the right triangle.
Opposite sides of a rectangle are congruent, so the side of the rectangle opposite the side that measures 7 also measures 7. That is the other leg of the right triangle. Now we use the Pythagorean theorem to find AC which is the hypotenuse of the right triangle.
a² + b² = c²
1² + 7² = c²
1 + 49 = c²
c² = 50
c = √50
c = 7.07
Answer: Yes, No Submit ·
Step-by-step explanation:
I got -10
1. create two ordered pairs based on the data so (1, 90) and (3, 70)
2. plug into the slope formula so (70 - 90)/(3 - 1)
then it's -20/2, which is -10
