Answer:
The ballon will hit the ground after 1 s.
Step-by-step explanation:
In this case we want to solve for x, but were given a equation to the height of the ballon, we can organize it in a way that isolates x on the left side of the equation so it can be used to what we want. So we have:
h = -16x^2 +16
h + 16x^2 = 16
16x^2 = 16 - h
x^2 = (16 - h)/16
x = sqrt(16 - h)/sqrt(16) = sqrt(16 - h)/4
When the ballon hits the ground it's height is 0 feet, so we substitute that on our equation and we'll have the right answer.
x = sqrt(16 - 0)/4 = sqrt(16)/4 = 4/4 = 1 s
Answer:
All four sets of numbers
Step-by-step explanation:
3 to the power of 2 is 9. real numbers are all numbers, whole numbers are the counting numbers plus zero, integers are whole numbers with their opposites ( 3 and -3), rational numbers are any numbers that can be written as a fraction, or is a decimal with an end or a repeated pattern to it.
Answer:
A. $2.26
Step-by-step explanation:
An equation for Harper's balance can be written similar to the one written for Raymond's balance. It will be ...
H(t) = 110(1.035)^t
For t = 2, the two balances will be ...
H(2) = 110(1.035^2) = 117.83
R(2) = 110(1.025^2) = 115.57
The difference is ...
$117.83 -115.57 = $2.26
Harper's account will have $2.26 more.
_____
As a quick estimate or sanity check, you can see that Harper's interest rate is 1% more than Raymond's. So, in 2 years, he will earn a little more than 2% more on his investment than Raymond earns. 2% of $110 is $2.20, so the difference can be expected to be slightly more than this.
Answer:
2(4b-1)
Step-by-step explanation:
1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2
Answer to first step: -10+8b+8
2. Add the numbers. It should be -10 + 8 which would give you -2
Answer to second step: -2 + 8b
3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2
Answer to third step: 8b - 2
4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2
Hope this helped!
