Debora [2.8K]3 years ago
5 0

Answer:

D

Step-by-step explanation:

Break it into 2 parts.

First Part

4s (5s^2 + 10s + 3)

20s^3 + 40s^2 + 12s

Second Part

2 (5s^2 + 10s + 3)

10 s^2 + 20s + 6

Now add the like terms

20s^3 + (40s^2 + 10s^2) + (12s + 20s) + 3

20s^3 + 50s^2 + 32s + 6

What are the possible values of x and y for two distinct points, (5, –2) and (x, y), to represent a function?
bonufazy [111]

The <em><u>correct answer</u></em> is:

Any real number for x except 5, and any real number for y.

Explanation:

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.  This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.

This means that 5 cannot be used for x in the other ordered pair.

Since there is no restriction on y in order to be a function, y can be any real number.

Here is a system of linear equations: y= x+4 y= -3x-8
ipn [44]

Answer:

  • A) (-3,1)

Step-by-step explanation:

<u>Given system of linear equations: </u>

  • y= x+4
  • y= -3x-8

---

  • x + 4 = -3x - 8
  • x + 3x = - 8 - 4
  • 4x = -12
  • x = -3

Then

  • y =-3 + 4 = 1

Solution is (-3, 1)

Correct option is A

The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.
beks73 [17]

Answer:

Lateral surface area of can = 47 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of given can = 3 inches

Height of given can = 5 inches

Find:

Lateral surface area of can

Computation:

Radius of can = 3 / 2 = 1.5 inch

Lateral surface area of can = Lateral surface area of cylinder

Lateral surface area of cylinder = 2πrh

Lateral surface area of can = 2πrh

Lateral surface area of can = 2(3.14)(1.5)(5)

Lateral surface area of can = 47.1

Lateral surface area of can = 47 inch² (Approx.)
