Draw a number line, or look for a number line online.

a. Count the number of units from 5 to 0. It is 5.

b. Count the number of units from -5 to 0. It is 5.

c. |5| means the absolute value of 5, and it represents the distance 5 is from 0 on the number line. The answer is 5.

d. |-5| means the absolute value of -5, and it represents the distance 5 is from 0 on the number line. The answer is 5.

PLEASE HALP MEH

Dmitry_Shevchenko [17]

Answer:

A.The scale factor is 0.25 ⇒ True

B.The scale factor is 4 ⇒ False

Step-by-step explanation:

See the attached figure.

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

A dilation that creates a smaller image is called a reduction.

As Shown, two right triangles, The first triangle is dilated to form the second triangle.

We can deduce that the second image is a smaller than the first triangle.

The hypotenuse of the first triangle = 4.4

The hypotenuse of the second triangle = 1.1

So, the scale factor = 1.1/4.4 = 11/44 = 1/4 = 0.25

We will check the options:

A.The scale factor is 0.25 ⇒ True

B.The scale factor is 4 ⇒ False

At what value of x does the graph of the following function f(x) have a vertical asymptote? f(x)=1/x+3

ratelena [41]

Answer:

Step-by-step explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

x + 3 = 0 ⇒ x = - 3 ← equation of vertical asymptote

In a GP the second and fourth terms are 0.04 and I respectively find the common ratio and the first term

Reptile [31]

Answer:

common ratio=0.5, a1= 0.08

Step-by-step explanation:

r=a3/a2

r=a4/a3

compare both we get:

a3/a2=a4/a3

subtitute a2=0.04 and a4=1

a3/0.04=1/a3

(a3)^2=0.04*1

(a3)^2=0.04

taking square root in both sides

a3=0.02

For r, r=a3/a2

subtitute a3 and a2 above

r=0.02/0.04

r=0.5 common ratio

For a1

r=a2/a1

0.5=0.04/a1

a1=0.04/0.5

a1=0.08
