Flura [38]

Answer:

3.75

Step-by-step explanation:

g(x)=60(1-0.5)^x, g(4)

g(4)=60(1-0.5)^4

g(4)=60(.5)^4

g(4)=60(0.0625)

g(4)=3.75

1.
Height h = 240 feet
We insert it into formula.
$240 = -16 t^{2} +128t$
Now we solve this for t:
$16 t^{2} -128t +240 = 0 /16 \\ t^{2} - 8t +15 =0 \\ t_{1} = 5 t_{2} = 3$

We have two answers as the rocket will pass this height on it's way up and down.

2.
Height h = 0 feet
We insert it into formula.
$0=-16 t^{2} +76t + 2$
Now we solve this for t:
$16 t^{2} - 76t -2 = 0 /2 \\ 8t^{2} - 38t - 1 = 0 \\ t_{1} = 5 t_{2} = -1$
We do not consider solution -1 as the time can not be negative. Our solution is 5s.

3.
Height at bottom of hill h = 0 feet
We insert it into formula.
$v^{2} = 64 * 0 = 0 ft/s$

Answer:

349800

Step-by-step explanation:

First Part:

The question tells you to multiply by 10 to the power of 4.

This implies that you can move the decimal point 4 numbers to the right

When you move the decimal two numbers to the right you get 3498

Then you got to move it two more numbers to the right

3498 can also be written as 3498.0000000000 (infinite amount of zeros)

So moving the decimal two more places you get 349800

Second Part:

10^4 = 10 * 10 * 10 * 10

= 10000

Count the zeros you get 4.

I want to know how they got (1.01125) as answer from the top question? Can someone plz help me just to explain it

faltersainse [42]

Answer:
_______________________
{1 + (0.045/4) } = 1.01125
____________________________

What is: "(0.045) / (4)" ???

Using a calculator: "(0.045) ÷ (4) = 0.01125 ".
______________________________________
Then: " 0.01125 + 1 = 1.01125 " .

6) use the steps to solve this system of equations. Show your work. Y=x+2 Y=x^2-4

zepelin [54]

y= x + 2 and y = x^2 - 4

Substitute mx + b for y

x^2 - 4 = x + 2

Solve for x

x^2 - 4 = x + 2

x^2 - x - 6 = 0

(x - 3)(x + 2) = 0

x - 3 = 0; x = 3

x + 2 = 0; x = -2

Substitute the first x value into the linear equation and solve for y

y = 3 + 2

y = 5

One solution is (3, 5)

Substitute the second x value into the linear equation and solve for y

y = -2 + 2

y = 0

Another solution is (-2 , 0)
