The percentage increase; you'll need to take the new value and subtract it by the old value.
16 - 13 = 3
Next, you'll divide 3 by the original value.
3 ÷ 13 = 0.23
And multiply by 100
The percentage increase of friends is 23%
We are given with the radical expression
√(27 x⁴ / 75 y²)
we can simplify this by dealing with the fraction first
√(27 x⁴ / 75 y²) = √( 9 x⁴ / 25 y²)
Then, take the square root of the coefficients and the variables
= 3x² / 5y<span />
As long as the equation has a solution of 26, it is fine. Let the solution = 26, and let solution = s
You will have to make a equation, in which when you plug in 26 for solution, it is the answer.
let x = a number
For example:
x - 10 = s
s = 26
x -10 (+10) = 26 (+10)
x = 36
x - 10 = 26, in which x = 36
hope this helps
Answer:
156.6 or 156 with a remainder of 3
Step-by-step explanation:
A] <span>A remote-control airplane descends at a rate of 2 feet per second. After 3 seconds it is 67 feet above the ground.
the point slope equation will be given as follows:
y-y1=m(x-x1)
where:
slope,m=2 ft/sec
(x1,y1)=(3,67)
thus plugging in the values in the formula, we obtain the point slope equation as follow:
y-67=2(x-3)
Answer:
</span>y-67=2(x-3)
b]The height of the plane after 8 seconds will be:
x=8 sec
but:
y-67=2(x-3)
substituting x=8 we get:
y-67=2(8-3)
y-67=2(5)
y=10+67
y=77
thus the height after 8 seconds is 77 ft
