It will take 2 hours for the car going 52 mph to reach the car going 26 mph.
The scale the speed of the car measured is:
D. Tens
<span>
since y = –1.5x² its domain is R=] -infinity, infinity[
the inverse of y
</span>–1/1.5 y = x² , and x = sqrt ((–1/1.5) y) , and f^-1 (x) = sqrt ((–1/1.5) x)
its domain is –1/1.5) x>=0, so x<=0,
from where, the range of y = –1.5x² is the interval ]-infinity, 0]
Answer:
-2.25
Step-by-step explanation:
We have that the mean (m) is equal to 500, the standard deviation (sd) 20
They ask us for P (x <455)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (455 - 500) / (20)
z = -2.25
Answer: 24 coins
Step-by-step explanation:
Answer:
(A) y - x
Step-by-step explanation:
Finding a:
- ax + x² = y² - ay
- ax + ay = y² - x²
- a(x+y)= (y+x)(y-x)
- a = y - x
Correct choice is (A)
