Answer:
Zero
Step-by-step explanation:
We are to find
Here the integral is of the form x varying from negative to positive
And negative limit = positive limit in dimension
Let us assume
A function is odd if f(x) = -f(-x) and even if f(x) = f(-x)
Let us check f(-x) = -f(x)
So f is an odd function.
As per properties of integration, we have
=0 if fis an odd function.
Our function f is odd and a = infinity
So we can apply this rule to find out the
integral value is zero.
Answer is d = 50.
Step by step. These are vertical angles so the (d + 70) will equal the opposite angle of 120.
Equation is d + 70 = 120.
Solve for d. Subtract 70 from both sides of the equal sign to solve for d.
d + 70 - 70 = 120 - 70
d = 50
Answer:
A)
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.
No Because the key is x times 5 to get y
However 199 time 5 is not 195 therefore the table is not proportional
Answer:
The forumula for finding area of the circle is \pi r^2.
Step-by-step explanation:
Let's find the radius of the mug:
r=\frac{d}{2}=\frac{8}{2}=4
Now, we can to express the area of each cookie in terms of pi:
Area= \pi *4^2=16\pi
