<h2>9 ft</h2>
Step-by-step explanation:
The height of kangaroo after it jumps is represented by the function
, where
is in seconds, height is in feet.
To find the maximum height that the kangaroo jumps, we need to maximise
.
The minimum/maximum value of a quadratic expression
is given by
.
As the coeffecient of quadratic term is negative, the function has a maxima.
Maximum value =
.
∴ Maximum height = 9 ft
For the answer to the question above, It m<span>eans Brian is switching from saving $25 dollars a week to $35 dollars a week. Because every week Brian will add $25 to his savings account (In week 1, Brian adds $25. In week 2 Brian adds $50. And so on). So to change from 25 to 35 would mean that Brian is saving more money every week ($10 to be exact). </span>
<span>And if you're curious, $350 stands for the amount of money Brian has initially (because at 0 weeks, Brian has $350 in his savings account).
I hope this helps</span>
→Answer:

→Step-by-step explanation:
Well the formula for the area of a circle is
.
<u><em>→Given information</em></u>
Pi is 3.142
radius is 4 cm
answer must be rounded to the nearest tenth
____________________________________________________________
So now we have to plug in the given information into the following formula
.
(3.142)(4)^2
So now we have to solve this formula using PEMDAS.
So 4 squared is 16 and 16*3.142 is 50.272cm^2.
The question clearly states the given answer must be rounded into the nearest tenth so 50.272 is 50.3 cm^2.
