The correct answer for the exercirse shown in the figure attached is the first option, which is: Calculate the area of the circle A and circle B and calculate the difference.

To calculate the area of the circle A and the circle B, you must apply the formula for calculate the area of a circle, which is shown below:

A=πr²

A is the area of the circle.
r is the radius of the circle.

To calculate the difference, you only have to substract the result of the area of the circle A and the area od the circle B:

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is $-8x^2 + 54x + 140$ .

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

= $-8(0)^2 + 54(0) + 140$

= $140$

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Find the equation of the line that

olganol [36]

Answer:

y= $\frac{1}{2}x-2$

Step-by-step explanation:

Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept

y=mx+b

2= $\frac{1}{2}$ (8)+b

2=4+b

B=-2

y= $\frac{1}{2}x-2$
