The length of ​ AB¯¯¯¯¯ ​ is 10 inches. A dilation with a scale factor of 25 is applied. What is the length of the image of ​ AB¯¯¯¯¯ ​ ?

Answers

Answer:

length of image of AB is 4 inches.

Step-by-step explanation:

Scale factor(k) is defined as the ratio of  image to the pre-image.

i.e,

k = \frac{\text{Image}}{\text{Pre-image}}

as per the statement:

The length of ​ AB ​ is 10 inches. A dilation with a scale factor of (2)/(5)

k= (2)/(5) =0.4 and Length of pre-image AB = 10 inches.

by definition of scale factor:

\text{length of image AB} = k \cdot \text{Length of Pre-image AB}

Substitute the given values we have;

\text{length of image AB} = 0.4 \cdot 10

Simplify:

\text{length of image AB} =4 inches.

Therefore, the length of image AB is 4 inches.

The answer is 4. 

I hope this helps. :)

Whats 416 divided by 4?

Answers

According to the division property when 416 is divided by 4 the resultant will be 104.

Given, 416 divided by 4.

The rules for division are:

(1) positive ÷ positive = positive

(2) positive ÷ negative = negative

(3) negative ÷ negative = positive

Here both the numbers are positive so by 1 rule the answer will be positive.

Now, Divide 416/4

⇒ 416/4

= 104.

Check:

100× 4 = 400

4 × 4 = 16

104 × 4 = 416

Thus the result will be 104.

104 Because 100*4 = 400 and 4*4 = 16 so add together and get 416

Harold buys a backpack thatcosts $24.80. It is on salefor 25% off. Harold also hasa coupon for an additional10% off the lowest price.What is the final price of thebackpack (not including tax)?

Answers

Final price of the backpack (not including tax) = $16.74

Given that

Initial cost of backpack = $24.80

First Discount = 25% off *Initial Cost =$  24.80 * (25)/(100) = $ 6.2  

So  modified  price = 24.80 - 6.2 = $18.6

Also Harold has a coupon with 10% on the modified price.

so we can write  10% of $18.6 = $ 1.86

so we can write the final price for the backpack = 18.6 - 1.86 =  $16.74

For more information  about discount please refer to the link below

24.80 ÷ 4 = 6.2, and 24.80 - 6.2 = 18.6. With the second coupon, another 1.86 is removed, making the backpack $16.74

What ten times a number increased by four is no more than twenty-five in numbers

Answers

10x+4<25 \n\n 10x<25-4 \n\n 10x<21 \n\n x<(21)/(10) \n\n \boxed{x \in (-\infty; (21)/(10))}
ten times a number. we'll call "a number" x:
10 * x
ten times a number increased by four. increased by is a fancy way of saying plus:
10 * x + 4
ten times a number increased by four is no more than twenty five. if a number is no more than 25, that means it's either less than 25 or equal to 25. so:
10 * x + 4 \leq 25\n10x+4 \leq 25

What is the effect on the graph of the linear parent function, f(x) = x, when f(x) is replaced by f(x + 5)?A) The graph of the line becomes steeper.
B) The graph of the line shifts horizontally right 5 units.
C) The graph of the line shifts vertically down 5 units.
D) The graph of the line shifts horizontally left 5 units.

Answers

Answer:

D) The graph of the line shifts horizontally left 5 units.

Adding a number, n, inside of the parenthesis with x would move the parent function n units to the left.




Here are the rules:
F(x + a) shifts a units left.
F(x - a) shifts a units right.

You can see this by taking for example f(x) = x^2 then f(x+5) = (x+5)^2, if you graph y=x^2 and y=(x+5)^2, you will see it is shifted 5 units to the right.
