The height h (in feet) above the water of a cliff diver is modeled by h=-16t^2+8t+80, where t is the time (in seconds). How long
Misha Larkins [42]
If this is algebra, then you will be using a parabola to solve this problem:
t=-b/2a
t=-8/2(-16) = 8/-32 = -1/4
t=-1/4=-0.25
h=-16(0.0625)+8(-0.25)+80
h=1-2+80
h=79
(-0.25,79)
then plug this ordered pair above and draw a line directly down the middle of it to use as a "mirror" and plug 2 different numbers(preferably 0 and 1) into the variable t to find the other two points and then reflect the two points over the "mirror" to get the last two points to graph your paprabola

ted wants to buy a skateboard that costs $59.00, but is on sale for 30% off. How much money will he save
STatiana [176]

Answer:

$17.70

Step-by-step explanation:

Hi,

What you want to do is to find 30% of $59

First, you convert 30% into decimal form by dividing it by 100

30%=0.3


Next, you want to find 30% of 59, so what you do is you take the new decimal form and multiply it by 59

0.3×59=17.7


Ted is saving $17.70

Tell whether the equation has one,zero or many solutions -(2x+2)-1=-x-(x+3)
PtichkaEL [24]

- (2x + 2) - 1 = -x - (x + 3)

-2x - 2 - 1 = -x - x - 3

-2x - 3 = -2x - 3

This is an identity and x can be any value

Answer many solutions

The sum of five consecutive numbers is 700, what is the first number?
Feliz [49]

Answer:

The first number is 138.

Step-by-step explanation:

Let the first number be <em>x.</em>

<em />

Then since they are consecutive numbers, the second number will be (<em>x</em> + 1), the third (<em>x</em> + 2), the fourth (<em>x</em> + 3) and the fifth being (<em>x</em> + 4).

We are given that their sum is 700. Therefore:

x+(x+1)+(x+2)+(x+3)+(x+4)=700

Solve for <em>x</em>. Combine like terms:

5x+10=700

Subtract 10 from both sides:

5x=690

Divide both sides by five. Therefore:

x=138

The first number is 138.
