Answer: 
Step-by-step explanation:
First integrate f'(x) so we can find the funtion f(x):
![4\int\limits {x} \, dx =4[\frac{1}{2} x^2]=2x^2+C=f(x)](https://tex.z-dn.net/?f=4%5Cint%5Climits%20%7Bx%7D%20%5C%2C%20dx%20%3D4%5B%5Cfrac%7B1%7D%7B2%7D%20x%5E2%5D%3D2x%5E2%2BC%3Df%28x%29)
The initial conditions say that when x = 0, the function equals 5. Let's write that down:
Therefore, the integration constant 'C' must equal 5. This means that our function is:
U could answer that question by adding 2.45+1.9=4.35
16:40 as a fraction is 16/40. 16/40 is 4/10 simplified
Answer: $45
Step-by-step explanation:
15/4 = 3.75
Each shirt costs $3.75
3.75 * 12 = 45
Answer:
Y=21
X=8
Step-by-step explanation:
In the middle there is a right angle
therefore 27 +3y=90
Y will be 21
Then x+27+63+8x+18=180
x=8
Hence 8+27+3(21)+8(8)+18=180
