First you chang top fractions into decimal add and divide that by 4 which is equal to 0.375 hope it helps.
Note that height is equal to 0 when time equals 0 and when time equals 4, but we are only concerned with time equal to 4
Answer: −0.125
Step-by-step explanation:
The formula for finding the area of a circle can be written in many ways. If the radius is given, the formula is A=πr², where A=area, π=22/7 or 3.14, and r is the radius.
If the diameter is given, then the formula is A=1/4πd², where A is the area, π is 22/7 or 3.14 and d is the diameter
Given that the diameter is 46 inches and π=22/7 or approximately 3.14, the formula we can use is A=1/4πd² where A=area, π is 22/7 and d is 46
A=1/4*22/7*46*46
A=16662.57 inches² (It is rounded to nearest hundredth)
1. f(-6)=12
2. k(-4)=-68
Further explanation:
We have two functions whose values we have to find on certain points.
In order to find the values of function, the value is put in place of variable in the function.
So,
<u>1. f(a) = -2a</u>
We have to find, f(-6)
So putting -6 in function

<u>2. k(x) = -3x^2+5x</u>
We have to find, k(-4)
So putting -4 in function
