The lowest point in Death Valley is Badwater at 282 feet below sea level. The highest point in
Finger [1]

Answer:

Step-by-step explanation:

Given

Badwater = -282ft

Telescope\ Peak = 11043ft

The position of badwater is negated because it is below sea level

The interpretation of the question, is to calculate the distance between the two given points.

This is calculated as:

Difference = Telescope\ Peak - Badwater

Difference = 11043ft - (-282ft)

Open bracket

Difference = 11043ft+282ft

Difference = 11325ft

<em>Hence, the distance between both is 11325ft</em>

What are the unit rates for  4/8 , 5/25, 36/6, 14/21, 18/30, 28/16, 56/35, 45/108, 12/42, 39/26
Artyom0805 [142]
How you find those is you just divide the rate and what ever answer you get you add a one on the bottom

Example: 1. 4/8

A water balloon is 5 feet above the ground when Sally launches it into the air. Use the quadratic equation 0 = -t^2 + 4t + 5 to
rodikova [14]

Answer:

t=5\ sec

Step-by-step explanation:

we have

-t^{2} +4t+5=0

Solve the quadratic equation to find the zero's or x-intercepts

Remember that

The x-intercepts are the values of x when the value of y is equal to zero ( water balloon reach the ground)

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

-t^{2} +4t+5=0

so

a=-1\\b=4\\c=5

substitute in the formula

t=\frac{-4(+/-)\sqrt{4^{2}-4(-1)(5)}} {2(-1)}

t=\frac{-4(+/-)\sqrt{36}} {-2}

t=\frac{-4(+/-)6} {-2}

t=\frac{-4(+)6} {-2}=-1

t=\frac{-4(-)6} {-2}=5

therefore

the solution is t=5\ sec
