First we need to differentiate y

$\\ \sf\Rrightarrow \dfrac{dy}{dx}$

$\\ \sf\Rrightarrow \dfrac{d}{dx}(-16x^2-110x+15)$

$\\ \sf\Rrightarrow -32x-110$

Now let it be 0

$\\ \sf\Rrightarrow -32x-110=0$

$\\ \sf\Rrightarrow -32x=110$

$\\ \sf\Rrightarrow x=|110/-32$

$\\ \sf\Rrightarrow x=3.44s$

Put it in y

$\\ \sf\Rrightarrow y=15-110(3.44)-16(3.44)^2$

$\\ \sf\Rrightarrow y=204.05ft$

It is estimated that there are 828 motor vehicles in the US it is estimated that there are 828 Motor vehicles in the US for ever

coldgirl [10]

Answer:

314 million

Step-by-step explanation:

Given that :

Number of motor vehicle in the U.S for every 1000 people = 828

If the number of motor vehicle in the United States = 260 million

Then,

Let x = number of people Given number of vehicles = 260,000,000

1000 people = 828 vehicles

x = 260,000,000

828x = (260,000,000 * 1000)

828x = 260,000,000,000

x = 314009661. 835

x = 314 million (approx)

Ten plus two times the quantity of a number plus four

yuradex [85]

The answer is 16x because if you add 10 and 2 you get 12 then add 4 you get is 16 but you need to multiply by x so you write it as 16x

A sail is in the form of a right triangle that is three times as high as it is wide. The snail is made from 6 square meters of m

lara31 [8.8K]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

Suppose the base of right triangle sail is b

Suppose the height of right triangle sail is h

It is given that, it is three times higher as it is wide.

$h=3b$

Area of right triangle is A = $\frac{1}{2}*b*h$

$6=\frac{1}{2}*b*h$

Plugging the value of h in terms of b

$6=\frac{1}{2}*b*(3b)$

$b^2=4$

$b=2$

Hence height h = $3*2 = 6$

Hecne the height of sail is 6 meters. : Answer

Hope it will help :)
