Answer:
50 minutes
Step-by-step explanation:
10 / 0.2 = 50
It takes 5 minutes for the snail to travel 1 inch, multiply that by 10 and we get 50 minutes.
The <em><u>correct answer</u></em> is:
Explanation:
To write a composite function, we apply one function to another given function. In this case, we want to find area in terms of time; this means that the function A(r) gets applied to the function r(t).
In order to do this, we replace r with r(t). We already know that r(t)=0.5+2t; this means we replace r with 0.5+2t:
A(r(t))=π(0.5+2t)²
To simplify this, we simplify the squared term:
A(r(t)) = π(0.5+2t)(0.5+2t)
A(r(t)) = π(0.5*0.5+0.5*2t+2t*0.5+2t*2t)
A(r(t)) = π(0.25+t+t+4t²)
A(r(t)) = π(0.25+2t+4t²)
Answer:
The last answer choice: Phillip will lose (1/2) of his points in his next crash.
Step-by-step explanation:
For every crash, Phillips points will continue to reduce by (1/2) the amount that he currently has. That means after 1 crash, he will 5,000 points left. After 2 crashes, he will have 2,500 points left. After 3 crashes, he will have 1250 points left. After 4 crashes, he will have 625 points left, and so on like that.
Answer:
Step-by-step explanation:
Multiplier: -175/3 Decrease: 23⅓ %
Step-by-step explanation: 75 = 250 - 3(d) d = -175/3 Y = 250 - (175/3)m
Where m is the no.
of months Y is the new value
(175/3)/250 × 100 = 70/3 %
Or 23⅓ %
