Answers

Answer:

B. The graph of h(x) opens downward.

D. The graph of h(x) is wider.

Step-by-step explanation:

The negative leading coefficient causes the graph to be reflected across the x-axis, making it open downward.

The leading coefficient magnitude less than 1 compresses the graph vertically, giving it a wider appearance.

Factor the polynomial expression 16y4 − 256x12.

Answers

Step-by-step explanation:

Using Difference of Squares,

16y⁴ - 256x¹²

= 16(y⁴ - 16x¹²)

= 16(y² + 4x⁶)(y² - 4x⁶)

= 16(y² + 4x⁶)(y + 2x³)(y - 2x³).

Step-by-step explanation:

16y4-256×12=16.(y4-16×12)

Isabel wants to start saving more money so that she can purchase new clothes for college. She has $200 and will add $5 to her savings every day.

Which equation models Isabel's savings, where n represents each day?

Answers

Answer:

y = 5n + 200

Step-by-step explanation:

y = mx + b

$5 will be added every day, so 5 is the m and n is the x.

$200 is an extra cost that doesn't repeat, so it's the b.

There is a cool trick you can do. Lets take 28 and square it.

First you round the number up. 28 rounded is 30. You rounded up by 2 (30-28=2) so you minus 2 from 28.

You are left with these two numbers, 26 and 30. Add a zero to the 26.

You now have 260 and 3 (you remove 0 on the 30 since you added it to the 26)

Then you multiply by 3.

260x3=780

Then you add the square of the number you rounded up too, which is 2.

You are left with this equation.

(2^2)+780= 784

28x28=784.

This works for numbers below 100 and integers

A wire 4 1/2 feet long is being cut into smaller pieces of wire, each 11/4 feet long. What is the maximum number of the smaller pieces of wire that can be cut from the original piece of wire?

Answers

Answer:

Step-by-step explanation:

Take 4 1/2 and turn it into just halves by multiplying 4•2 and then adding it to one. 9/2 then multiply that by 2 because you need the denominator to be 4 getting 18/4. Then subtract 11/4 you end up getting 9/4. So technically you have 2 pieces but if you want them both to be 11/4 you only have one

Step-by-step explanation:

Angle CAB = 33 degrees (Z-figure)

Angle ACE = 180 degrees (line), therefore angle ACB = 180 - 5x.

Sum of all angles in the triangle should equate to 180 degrees.

Now the sum is of all angles in triangle ABC is:

CAB + ABC + ACB = 33 + (180 - 5x) + 2x = 213 - 3x

So 213 - 3x should equal 180.

213 - 3x = 180 <=> -3x = -33 <=> x = 11
