PLEASE HELP Path of A Ball
The path of a ball in flight is given by h(x) = -0.23(x - 3.4) + 4.2 where x is the
horizontal distance in meters and h(x) is the height in meters,
a.
b.
Find h(2) and give a real-world meaning for this value,
find the x-values for h(x) = 2, and describe the real-world meaning of
these values.
How high was the ball when it was released?
How far will the ball go before it hits the ground?
C.
d.

step-by-step explanation:

560

hope this : )

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
