9514 1404 393

Answer:

  81 m

Step-by-step explanation:

Since x is seconds after takeoff, the value of x at takeoff is 0. You are being asked to find H(0).

  H(0) = -3(0 -3)^2 +108 = -3(9) +108 = 81

The height of the hovercraft at the time of takeoff is 81 meters.

Step-by-step explanation:

t in 1200m:

t =  \frac{4500}{x}  \\ x = 1200 \\ t = 4500 \div 1200 = 3.75

t in 3750:

t =  \frac{4500}{x}  \\ x = 3750 \\ t = 4000  \div 3750 = 0.12

difference is:

3.75-0.12 = 3.63

How to convert 0.0001 to a power of 10 please thanks
alexandr402 [8]
Your answer is 10^(- 4). 

Think about how exponents with a base 10 work. 10^1 = 10, 10^2 = 100, 10^3 = 1000. It's just add a zero to the right side as you go up. 

Then think about 10^0. Anything to a zero power is 1. Only way to go is into negative exponents now. If for positive exponents on 10 we add a zero to the right side, then for negative exponents we add them to the left. Only difference is we have a decimal.

10^(- 1) = 0.1
10^(- 2) = 0.01
10^(- 3) = 0.001

And then your answer

10^(- 4) = 0.0001

Hopefully that explanation makes sense. Exponents can be rough to explain when you're not face-to-face or using some sort of live animation to talk through it. If you're still confused, I'd suggest talking to your instructor.

Duffs Co. is growing quickly. Dividends are expected to grow at a 24% rate for the next three years, with the growth rate fallin
SOVA2 [1]

Based on the fact that Duffs Co. dividends grow at 24% for three years and then 6%, the current share price of the company is $63.29.

<h3>What is Duffs Co. current price?</h3>

First, find the price of the stock in year 3 when the stock grows at 6%:

= (1.90 x 1.24³ x 1.06) / (0.11 - 0.06)

= $76.79

This amount is the terminal value. You are to take the present value of this amount along with the present value of the dividends up to year 3:

= ((1.90 x 1.24) / 1.11) + ((1.90 x 1.24²) / 1.11²) + ((1.90 x 1.24³) / 1.11³) + 76.79 / 1.11³

= $63.29

Answer and working out please!
frosja888 [35]

Answer:

17.0710678119 and 2.92893218813

Step-by-step explanation:

Theoretically, the wire should come out to be x+y=80,

and the sum of the areas of the squares should be (x/4)^2+(y/4)^2=300.

x/4 and y/4 being the length of one side of the square, we would then square that to find the area. The total wire is all x+y=80. X being one part and Y being the other.

Theoretically, using systems. i found the answers: 68.2842712474619,11.715728752538098

Again, these numbers are very large, and I they actually do both add up to each amount basically perfectly. If your teacher is asking for a rounded answer, that would've been helpful to know. But again, theoretically, those are the answers.
