We have that
Her house is -----------------------24 feet tall
Her model is----------------------- 8 inches tall
The inch is a unit of length used primarily in the imperial and U.S.
customary measurement systems, representing 1/12 of a foot
in
=ft * 12.000
24
feet=12*24=288 inches
Her house is -----------------------288 inches tall
Her model is----------------------- 8 inches tall
288/8=36 scale of reduction
Her
brother is 5 feet tall
<span>The figurine in the model that
represents her brother (5/36)</span>=0.138889 feet
<span>0.138889*12=1.67 inches</span>
For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).
For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.
Rinse and repeat question 12 for question 13
30 ÷ 3 = 10 = 1/3. So 10 students play sports. 10 ÷ 5 = 2 = 1/5, so 2 × 2 = 4 = 2/5. Your answer is 4 students. I hope this helps!
The answer is c you must look at key words i learned my key words
