Mr.Evans is paid $9.20 per hour for the first 40 hours he works in a week.He is paid 1.5 times that rate for each hour after tha
yKpoI14uk [10]

Answer:

I do not agree.  If Mr. Evans worked 42.25 at a rate of $9.20 per hour for the first 40 hours and 1.5 times that rate after, he would have made a total of $399.05.  

Step-by-step explanation:

In order to find the total amount that Mr. Evans would have earned last week, we need to first calculate how much he earned in his regular pay at 40 hours.  For up to 40 hours, Mr. Evans makes $9.20 per hour, so his total wages earned after 40 hours is:  40 x 9.2 = $368.00.  However, Mr. Evans also worked 2.25 hours of overtime at a rate of 1.5 times $9.20 or 9.2 x 1.5 = $13.80.  At $13.80 for 2.25 hours, Mr. Evans would earn:  13.80 x 2.25 = $31.05.  When you add his base pay of $368.00 plus his over time pay of $31.05, you get a total of $399.05.

Amir stands on a balcony and throws a ball to his dog, who is at ground level.
Mariana [72]

Answer:

3 seconds

Step-by-step explanation:

To find the highest point, we want to find the vertex of the parabola.  Since the function will be negative, the vertex will represent the highest point.  

To find the vertex we want this equation in vertex form:

y=a(x−h)2+k

and the vertex will be (h,k)

We can expand the equation h(x)=-(x+1)(x-7) to be:

h(x) = -x^{2} +6x+7

To get the vertex form we need to complete the square.

The vertex form is :

-(x-3)^{2} +16

so our vertex is (3,16)

This means the highest point will be 16 when x = 3
