Answer:
t = 21
Step-by-step explanation:
The ball strikes the groujd when h = 0.

Since time must be positive, t = 21.
Answer:
∠ 1 = 105° , ∠ 2 = 75°
Step-by-step explanation:
Since the lines are parallel then
∠ 2 = 75° ( corresponding angle )
∠ 1 and ∠ 2 are adjacent angles and supplementary, thus
∠ 1 = 180° - 75° = 105°
Answer:rs 1636.25
Step-by-step explanation:
Answer:
Step-by-step explanation:
The parent function here is y = log x, where 10 is the base.
The derivative of y = log x is dy/dx = (ln x) / ln 10.
The derivative of y = log (ax+b) is found in that manner, but additional steps are necessary: differentiate the argument ax + b:
The derivative with respect to 10 of log (ax + b) is:
dy/dx = [ 1 / (ax + b) ] / [ ln 10 ] *a, where a is the derivative of (ax + b).
Alternatively, we could express the answer as
dy/dx = [ a / (ax + b) ] / [ ln 10 ]
Answer:
D, B, C, A
Step-by-step explanation:
D is the x coordinate of the vertex of the function because the greatest daily profit means the vertex of the parabola. and since x represents price, the answer is D
B is the y coordinate of the vertex of the function because the max profit means you are looking for the highest or lowest point of the parabola. And since the leading coefficient is -10, that means the opening is downward and there is a max, not min value.
if the make no money ($0 daily profit) which is the y value, that means you are looking for the x-int. This is because x-int if when y = 0. the answer is c
y int is when x is 0, so the answer is A
