the answer is 89
Step-by-step explanation:
it does not matter if the number is negative the absolute value is the number inside the lines
Answer:
180 degree clockwise rotation about center and a dilation of 0.5.
Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P = 4x
The rate of change of P with respect to x is
P'(x) = 4 (independent of x)
When A = 49 m², then x = 7 m.
The rate of P is 4.
Answer: 4
14 students in 21 student got an A on the test so 14/21 people got A. the numerator and the denominator are both divisible by 7 so the simplest form of this fraction would be 2/3
Answer:
The answer is (d)
Exponential decay function
Step-by-step explanation:
∵ y = 0.8^x
∵ 0.8 < 1
∴ 0.8^x is decreasing ⇒ exponential decay function
Ex: 0.8^-4 = 2.441 ⇒ 0.8^4 = 0.4096
when x increase the value of 0.8^x decrease
∴ The answer is (d)
