Set up an equation 5x+6x+7x=40 and solve for x
Answer:
C
Step-by-step explanation:
An approximation of an integral is given by:
First, find Δx. Our a = 2 and b = 8:
The left endpoint is modeled with:
And the right endpoint is modeled with:
Since we are using a Left Riemann Sum, we will use the first equation.
Our function is:
Therefore:
By substitution:
Putting it all together:
Thus, our answer is C.
*Note: Not sure why they placed the exponent outside the cosine. Perhaps it was a typo. But C will most likely be the correct answer regardless.
45 times 0.15= 6.75
45+6.75= 51.75
The answer is 51.75
Answer:
I think it is 75 square inches
Step-by-step explanation:
I believe this because if the base is a square, in order to find the area of a square it is base times height so in this case 5*5. So we have 25 for the base and to find the area of each triangle it is base times height divided by 2 and in this case (5*5)/2 which is 12.5. So since their are 4 triangles it is 12.5*4 which is 50 and plus the base area which is 25, so the ANSWER is 75 square inches.
Using linear function concepts, it is found that the unit rate in dollars per square yard is of $1.35 for Company A and of $2.05 per Company B.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem, for company A, the function is:
A: C = 1.35y + 100.
For company B, the function is:
B: C = 2.05y.
Considering the slopes, the unit rate in dollars per square yard is of $1.35 for Company A and of $2.05 per Company B.
