Please help. A skyrocket is launched from a 6 foot high platform with initial speed 200ft/s. The polynomial -16t^2 + 200t + 6 gives the height in feet the skyrocket will rise in t seconds. How high will the rocket rise in 6 seconds

Answers

Answer 1

Answer:

The height of the rocket after 6 seconds is 630 feet

Functions and values

Given the polynomial function that represents the height of the rocket expressed as:

f(t) = -16t^2 + 200t + 6

If the time the rocket take to rise is 6 seconds, hence;

f(6) = -16(6)^2 + 200(6) + 6

f(6) = - 576 + 1200 + 6

f(6) = 630 feet

Hence the height of the rocket after 6 seconds is 630 feet

An element with Mass 630 grams decays by 18.8% per minute. How much of the element is remaining after 7 minutes, to the nearest 10th of a gram?

Answers

Answer:

146.6 grams

Step-by-step explanation:

We have been given an element with Mass 630 grams decays by 18.8% per minute.

We will use exponential decay function to solve our given problem.

$y=a\cdot (1-r)^x$ , where,

y = Final amount,

a = Initial amount,

r = Rate of decay in decimal form,

x = Time.

$18.8\%=(18.8)/(100)=0.188$

Substitute the given values:

$y=630\cdot (1-0.188)^7$

$y=630\cdot (0.812)^7$

$y=630\cdot 0.232751347$

$y=146.633349$

$y\approx 146.6$

Therefore, 146.6 grams of the element is remaining after 7 minutes.

$630 * {81.2}^(7)$

30% of ____ is 90. Enter the unknown value that makes this statement true

Answers

300 is the unknown value you're looking for.

°° Why?

Great question! Let's find out! ↓ ↓ ↓

If 90 ÷ 3 = 30, then multiply 30 by 10, which makes 300 to get your answer. It makes perfect sense, doesn't it? :)

So, just fill in the blank!

30% of 300 is 90.

HAHA! We figured it out!

↑ ↑ ↑ Hope this helps! :D

So 90 divided by 3 is 30 so you multiply 30 by 10 and get 300. The answer is 300 in other words

-4(n-6)=12 how do I get the answer

Answers

If you would like to solve the equation - 4 * (n - 6) = 12, you can calculate this using the following steps:

- 4 * (n - 6) = 12
- 4 * n + 4 * 6 = 12
- 4 * n = 12 - 4 * 6
- 4 * n = 12 - 24
- 4 * n = - 12 /(-4)
n = 12 / 4
n = 3

The correct result would be 3.

-4(n-6)=12
Distribute -4 to the numbers in the parentheses;
-4n+24=12
-4n=-12
n=3
Hope this helps.

Let r>0 -π<θ<π be real. Calculate all the values of $Re( (ln(z))/(z))$

where $z=r(cos(\theta)+sin(\theta))$ .

Answers

For a real z, ln(z)/z is always a real number, so the Re() is quite useless.

Thus we just need to write $ln(z)/z=ln(r)+ln(\cos(\theta)+\sin(\theta))$ , and we can't simplify any more.
