tresset_1 [31]
To solve for the time it reach the maximum height, you must solve the first derivative of the function and equate it to zero

<span>h(t) = −4.9t^2 + 14.7t + 1</span>
dh/ dt = -9.8t + 14.7
then equate to zero
-9.8t + 14.7 = 0
solve for t
t = 1.5 s

then the maximum height is when t = 1.5

<span>h(t) = −4.9t^2 + 14.7t + 1
h(1.5) = </span><span>−4.9(1.5)^2 + 14.7(1.5) + 1
h(1.5) = 12.025 m

Please can you help me?
Gennadij [26K]

Answer:

\large\boxed{C)\ \dfrac{3}{4}}

Step-by-step explanation:

\text{We know:}\ P(A')=1-P(A)\\\\\text{Therefore}\\\\P(A)-3\cdot P(A')=0\iff P(A)-3\cdot(1-P(A))=0\\\\\text{use the distributive property}\ a(b+c)=ab+ac\\\\P(A)+(-3)(1)+(-3)(-P(A))=0\\\\P(A)-3+3P(A)=0\qquad\text{add 3 from both sides}\\\\P(A)+3P(A)=3\\\\4P(A)=3\qquad\text{divide both sides by 4}\\\\P(A)=\dfrac{3}{4}
