April shoots an arrow upward at a speed of 80 feet per second from a platform 25 feet high. The pathway of the

zaharov [31]

Answer:

The maximum height of the arrow is 125 feet.

Step-by-step explanation:

The pathway of the arrow can be represented by the equation,

$h = -16t^2 +80t + 25$ .....(1)

Where h is height in in feet and t is time in seconds.

It is required to find the maximum height of the arrow. For maximum height, $\dfrac{dh}{dt}=0$ .

So,

$\dfrac{d(-16t^2 +80t + 25)}{dt}=0\\\\-32t+80=0\\\\t=\dfrac{80}{32}\\\\t=2.5\ s$

Put t = 2.5 s in equation (1). So,

$h = -16(2.5)^2 +80(2.5) + 25\\\\h=125\ \text{feet}$

So, the maximum height of the arrow is 125 feet.

What is an equation of the line that passes through the points (-4, -5) and (-8, -2)?

nikklg [1K]

Solution:

Step-1: Find the slope of the line.

Formula of slope: y₂ - y₁/x₂ - x₁

y₂ - y₁/x₂ - x₁ = Slope
=> -2 - (-5)/-8 - (-4) = Slope
=> -2 + 5/-8 + 4 = Slope
=> 3/-4 = Slope

Step-2: Use the point slope formula to determine the slope.

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

y - y₁ = m(x - x₁) = Equation of line
=> y - (-5) = -3/4{x - (-4)} = Equation of line
=> y + 5 = -3/4{x + 4} = Equation of line
=> y + 5 = -3x/4 - 3 = Equation of line
=> y = -3x/4 - 8 = Equation of line

The equation of the line is y = -3x/4 - 8.

Ainat [17]

Answer:

$\Huge\boxed{z$

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

$\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25$

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25
