Answer:
C($)= (x²/2 +11x)5.75
Step-by-step explanation:
Let's assume the height= x
The base= x+22
Area= 1/2(base*height).
Area= 1/2((x+22)(x))
Area= x²/2 +11x
Cost per ft= $5.75
Cost for painting the triangular mural C
C($)= (x²/2 +11x)5.75
Answer:
cos60°
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , then
sin30° = cos(90 - 30)° = cos60°
You can use the compound growth to work this out,
Firstly you need to make a multiplier for -6%;
1-(6/100) = 0.94
The you times the amount of money by 0.94 to the power of 4 because you are working out 4 years:
230000*0.94^4 = 179527.26
The answer is $179527.26,
Hope this helps! :)
If the question is 2w+2L=24 than the answer is 6-w=L
but if the question is 2w+21=24 the answer is w=3/2
