The third one is the correct answer
instead of going through the long process of the simultaneous equation just input the first number for the x into the equation and 2nd for y and you get your answer
The equation is y=-2x ^ 2 + 4 x + 30 that’s the equation thru the proabola but if you do point slope form then it is y=18x+54 so it depends what your working on in class
Answer:
The answer to this is 4 and 9 over 16.
Step-by-step explanation:
The expression is 3 + (2 + 8)^2 ÷ 4 × 1 over 2 to the power of 4 . it can be represented mathematically as
3 + (2 + 8)^2 ÷ 4 × (1/2)^4
using PEMDAS
parenthesis come first
3 + 10^2 ÷ 4 × (1/2)^4
exponential comes next
3 + 100 ÷ 4 × 1/16
3 + 25 × 1/16
3 + 25/16
(48 + 25)/16
73/16
4 9/16
Answer:
The radius is growing at a rate of 
ft per minute.
Step-by-step explanation:
From the information given we know that
And we know as well that .
Since everything is changing with the time we can compute the implicit derivative and we would get that
We are told that we are looking for how fast is the radius growing at the instant when the radius has reached 1 ft, therefore 
And when we solve for
