Answer:
Hopefully, this is your desired setup. (I noticed the formula you have to fill in there.)
Have a good day.
Step-by-step explanation:
Hi.
You could use the percent change formula.
Since we know it is a percent increase then we will do new-old instead of old-new:
x is the new amount of shampoo.
16.5 is the original amount (old) of shampoo.
The percent increase is 30%=0.30 .
So we have the following equation:
We could have found the equation like this:
Subtract 16.5 on both sides:
Divide both sides by 16.5:
By us of symmetric property of equality:
Answer:
No spam no help
Step-by-step explanation:
Here, Function: h(t)= -16t² + 70t + 40
So, put the value of t, (time at which you want to calculate the height)
h(1) = -16(1)² + 70(1) + 40
h(1) = -16 + 110
h(1) = 94
Now, h(2) = -16(2)² + 70(2) + 40
h(2) = -64 + 180
h(2) = 116
h(3) = -16(3)² + 70(3) + 40
h(3) = -144 + 250
h(3) = 106
In short, Your height depends on time, and at each time it would be different, can be expressed by the coordinates on a Graph: (1, 94) (2, 116) (3, 106)
Hope this helps!
Answer:
0.046
Step-by-step explanation:
Data:
N = 4
H = 2
M = 80
Calculation:
D
add 49 to both sides to get x by itself
x^2 - 49 = 0
+49 +49
square root both sides to get rid of the square
√x^2 = √49
x= ±7
since both -7 and 7 are square roots to 49, it’s D
