The formula h-15 =3.2t, when was the height 31 inches

1 answer:

8 0

Plug in 31 where h is assuming that's what the variable h represents.

31 - 15 = 3.2t
16 = 3.2t
Divide both sides by 3.2

t = 5

What is the value of d to the nearest tenth?

Ghella [55]

Answer: $d=13.8$

Step-by-step explanation:

A line that cuts a circle at two points is called "secant".

There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".

According the Intersecting Secant Theorem:

$(14)(14+20)=(16)(16+d)\\(14)(34)=(16)(16+d)$

Having this expression, the next step is to solve for "d":

Use Distributive property:

$476=256+16d$

Subtract 256 from both sides:

$476-256=-256+256+16d$

$220=16d$

Divide both sides by 16:

$\frac{220}{16}=\frac{16d}{16}\\\\13.75=d$

The value of "d" rounded to the nearest tenth is:

$d=13.8$

One day at football practice, Darrell, the kicker, punted the ball so that its height in feet above the ground was given by the

nika2105 [10]

When the football is 81 feet high, it will be √ 3 / 8 seconds

<h3>Function</h3>

Function relates input to output. Therefore,

h(t) = - 16t² + 75

Therefore,

t = number of seconds

h(t) = - 16t² + 75

h(t) = 81 ft

Therefore,

81 = - 16t² + 75

- 16t² = 81 - 75

- 16t² = 6

divide both sides by -16

t² = 6 / -16

t² = - 3 / 8

square root both sides

t = √ 3 / 8 seconds
