Without using technology, describe the end behavior of f(x) = 3x32 + 8x2 − 22x + 43.

F(x) = 3x^32 + 8x^2 -22x +43

The ends of all the polynomials with even degree behave like quadratic functions.

Given the the coefficient of x^32 is positive, the function opens upwards. Then the two ends go up.

Which situation represents a proportional relationship?

lyudmila [28]

Answer:

D. The cost of purchasing avocados for $1.75 per pound plus a shipping fee of $0.16 per pound.

Step-by-step explanation:

A linear relationship is of the form $y=mx+b$ , where, $m$ is the unit rate and $b$ is the fixed value (constant).

For a proportional relationship, the value of $b=0$ and thus it is of the form $y=mx$

Let us check each option and express it in the form above.

Option A:

Given:

Unit rate of purchasing a basket of apples, $m=\$ 1.25$

Fixed price for the basket, $b=\$ 5$

Since, $b \ne 0$ , therefore, it is not a proportional relationship.

Option B:

Given:

Unit rate of purchasing a banana, $m=\$ 5$

Fixed price for the box, $b=\$ 3$

Since, $b \ne 0$ , therefore, it is not a proportional relationship.

Option C:

Given:

Unit rate of purchasing a lime, $m=\$ 0.65$

Discount from total cost, $b=\$ 1$

Since, $b \ne 0$ , therefore, it is not a proportional relationship.

Option D:

Given:

Unit rate of purchasing an avocado = $\$ 1.75$

Unit rate of shipping = $\$ 0.16$

Therefore, total cost per pound is the sum of the unit rates of purchasing and shipping. So,

Total cost of avocados per pound, $m=1.75+0.16=\$ 1.91$

There is no fixed cost on this. So, $b=0$

Since, $b = 0$ , therefore, it is a proportional relationship.

Therefore, the correct option is D.

Which of the following is a result of shifting a circle with equation (x + 3)2 + (y - 2)2 = 36 right 3 units? A.Both the x- and

Artyom0805 [142]

We have that
(x + 3)² + (y - 2)² = 36----------> (x + 3)² + (y - 2)² = 6²

we know that
the equation of a circle is of the form
(x-h)²+(y-k)²=r²
where (h,k) is the center and r is the radius
in this problem
the center of the circle is the point (-3.2) and the radius is r=6 units
so
if shifting a circle right 3 units
then
the center will be-----> (-3+3,2)-------> (0,2)

therefore

the answer is the option
B.The x-coordinate of the center of the circle increases by 3.
