The function f(x) = −(x + 5)(x + 1) is shown. What is the range of the function? all real numbers less than or equal to 4 all real numbers less than or equal to −3 all real numbers greater than or equal to 4 all real numbers greater than or equal to −3

### Answers

ANSWER

all real numbers less than or equal to 4.

EXPLANATION

The given function is

Expand

a=-1,b=-6,c=-5

The x-value of the vertex is given by

a=-1,b=-6,c=-5

The y-value of the vertex is

Since a=-1, the function opens downwards.

The highest value is the y-value of the vertex which is 4.

Therefore the range is all real numbers less than or equal to 4.

The correct choice is A.

all real numbers such that y is less than or equal to 4

How many 2/3 's make up 4 1/5

### Answers

Answer:

6³/₁₀

Step-by-step explanation:

Number of bits = Total amount/Size of each bit

= (4⅕)/(⅔)

Convert the mixed number to an improper fraction

No. = (²¹/₅)/(⅔)

Invert the denominator and change division to multiplication

No. = ²¹/₅ × ³/₂

Multiply numerators and denominators.

No. = ⁶³/₁₀

Convert the improper fraction to a mixed number.

No. = 6³/₁₀

It takes 6³/₁₀ ⅔s to make up 4⅕.

Layla wants to build a wooden box with a volume of 454545 cubic centimeters. She started with a width of 3\text{ cm}3 cm3, space, c, m and a height of 3\text{ cm}3 cm3, space, c, m. How long should Layla make the box?

### Answers

Answer:

50,505 cm

Step-by-step explanation:

In order to calculate this you just have to calculate the length necessary to create a wooden box with the volume of 454545 cubic centimeters, and now you just have to calculate since you have the base of the area, measuring 3 cm by 3 cm, that would be 9 square centimeters, so you just have to divide the desired volume by 9 square centimeters:

454545/9=50,505 cm

So the length of the wooden box should be 50,505 cm in order to have a 454545 cubic centimeters wooden box.

The thickness of a sheet of paper is approximately 1.03 x 101 millimeters. A ream of paper is 500 sheets. What is the thickness of a ream of paper in standard notation?

### Answers

Answer: One ream is about 500 sheets of paper and 5.2 cm thick. Given this information, find in cubic centimeters the volume of one sheet of letter - size paper. A sheet of letter size paper's dimensions are about 21.5 cm by 27.9 cm.

Step-by-step explanation: The thickness of a sheet is 5.2/500 cm = 0.0104 cm

Vol = 0.0104*21.5*27.9

V = 6.23844 cc

suppose f(x)=x^2 and g(x)=(1/5x)^2. Which statement best compares the graph of g(x) with the graph of f(x)?

### Answers

Answer:

g(x) is the image of f(x) after stretched horizontally

by scale factor = 5

Step-by-step explanation:

∵ f(x) = x² ⇒ quadratic function

∵ g(x) = (1/5 x)² ⇒ The image of f(x) after one transformation

* Stretches or compresses horizontally:

It means stretches away from the y-axis

or compresses toward the y-axis

* If f(x) = (ax)² :

∵ |a| > 1 is a compression by factor of 1/a

∵ 0

mean is adding all the terms and dividing by number of terms so once you add them all you be 108 and then divide by 9 giving you the mean, 12

Answer:

The mean should be 12.

Step-by-step explanation:

To find the mean of a range of numbers, you must simply add all of the numbers together and divide by how many numbers there are in the group.

In this case, I did 15+11+10+11+14+10+15+10+12, which came to be 108. I divided that by 9, since there are nine numbers, which gave me 12.

Hopefully this helps!
