Which types of dilation are the given scale factors?

Mathematics
2 answers:
Neporo4naja [7]3 years ago

Answer:

−4  is an expansion; 2.5  is an expansion; 2/3  is a contraction; and −3/4 is a contraction.

Step-by-step explanation:

In a dilation, a scale factor greater than 1 or less than -1 is an expansion.  It will make the figure larger.  This means that -4 is an expansion, since it is less than -1, and 2.5 is an expansion, since it is greater than 1.

A scale factor that is greater than -1 but less than 1 will be a contraction.  It will make the figure smaller.  This means that 2/3 is an expansion, since it is less than 1, and -3/4 is a contraction, since it is greater than -1.

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg? Select one:
saveliy_v [14]
H = 70ft.
P = 35ft.
B = ?

H^2 = P^2 + B^2
70×70 = (35×35) + B^2
B^2 = 4900-1225
B = √3675
B = 35√3 ft.

Choose the symbol that correctly compares the fractions below.<br> 8/9 ? 1/9
gladu [14]

Answer:

Which means that this equation is also true: 8/9 > 1/9

Step-by-step explanation:

Is 8/9 less than 1/9? Is 8/9 smaller than 1/9? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

8/9 = 0.889

1/9 = 0.111

Then, we compare the two decimal numbers to get the answer.

0.889 is not less than 0.111.

Therefore, 8/9 is not less than 1/9 and the answer to the question "Is 8/9 less than 1/9?" is no.

What is the equation of the line?
djverab [1.8K]

Answer:

y = 1/2 - 3/2

Step-by-step explanation:

All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].

-3 = 1/2(-3) + b

-3 = -1.5 + b

-1.5 = b

We can put all the information we know/solved for into the formula.

y = 1/2 - 1.5

Best of Luck!
