Answer:

B

Step-by-step explanation:

The measure of the frequency of exposure is how often the target audience is exposed to a communication within a specified period of time. In this case it was aired only once and reached 500 million viewers even though in later years it was aired also on other television programs

an object is launched at 25 m/s from a height of 80 m. the equation for the height (h) in terms of time (t) is given by h(t)=4.9
Aneli [31]

There must be minus sign with 4.9 .

h(t) = -4.9t^2+25t +80

The given equation is the equation of parabola , which is maximum at its vertex, and the formula of vertex is

t=-\frac{b}{2a}=-\frac{25}{2(-4.9)}  = 2.55 seconds

So the height is maximum at t=2.55 seconds and to find the maximum height , we need to plug 2.55 for t , that is

h(2.55)=-4.9(2.55)^2+25(2.55)+80 = Approx \ 112 \ m

So the maximum height is 112 m .

Can you form a right triangle with the three lengths given? Why or why not? 7 in., 24 in., 25 in.
MA_775_DIABLO [31]
Recall that using the pythaogorean theorem, which is only for right-triangles, the longest leg squared is the sum of the other two squared, namely c² = a² + b², now, if those units above are of a right triangle, then 25² = 7² + 24².

do they check out? if they do, then yes, you can make a right-triangle, if not, they nope.

Write the equation of the line that passes. Throught the point (-2,1)and (0,8)put your aswer in fully reduce point slope form un
Soloha48 [4]

Answer:

Step-by-step explanation:

first, we need to find the slope

slope = (y2 - y1) / (x2 - x1)

(-2,1)...x1 = -2 and y1 = 1

(0,8)...x2 = 0 and y2 = 8

now sub

slope = (8 - 1) / (0- (-2) = 7/(0 + 2) = 7/2

point slope form : y - y1 = m(x - x1)

using point (-2,1)....x1 = -2 and y1 = 1

slope(m) = 7/2

now sub

y - 1 = 7/2(x - (-2) =

y - 1 = 7/2(x + 2) <==== here is one answer

y - y1 = m(x - x1)

using point (0,8)...x1 = 0 and y1 = 8

slope(m) = 7/2

now sub

y - 8 = 7/2(x - 0) <===== another possible answer

Which of the following could be the number shown on the number line?
kari74 [83]

Answer:

I believe your answer would be C. square root of 67

Step-by-step explanation:

If 8 is the square root of 64 and the missing number is just over 8, square root of 72 would be too much and A. and D. would be too little. I do deeply apologize if this is incorrect.
