We are given the equation:
s(t) = gt² + v₀t + s₀
g=-4.9, v₀ =19.6 and s₀=24.5
plugging these values in the equation we get,
s(t)=-4.9t² +19.6t +24.5
Non when it hits the ground final height s(t) will be 0
0=-4.9t² +19.6t +24.5
first option is correct
Answer:
Height: 300
Width: 1000
Step-by-step explanation:
All you have to do is look at where the lines start and end on the graph for instance the top is at 0 and the very bottom line is at 300 so that means its 300 feet tall.
Answer:
Sure
Step-by-step explanation:
:)
We will start off working on the right hand side.
<span>cot x - tan x </span>
<span>= [cos x / sin x] - [sin x / cos x] </span>
<span>= [(cos x)^ 2 - (sin x)^2] / [sin x cos x] </span>
<span>This is where it gets a bit tougher if you do not have your formula list with you. </span>
<span>(cos x)^ 2 - (sin x)^2 = cos(2x) </span>
<span>sin 2x = 2 sin x cos x </span>
<span>Note that by arranging the second formula, we will have sin x cos x = (1/2) sin 2x </span>
<span>Hence, we will get: </span>
<span>[(cos x)^ 2 - (sin x)^2] / [sin x cos x] </span>
<span>= [cos 2x] / (1/2)[sin 2x] </span>
<span>= 2[cos 2x] / [sin 2x] </span>
<span>= 2cot 2x </span>
Answer:
x=3
Step-by-step explanation:
By vertical line test, x=3 fails because more than 2 points have the same x value. Functions must pass the vertical line test.
