You do the same as if it was positive you will multiply -4*-4 to get 16 and then you will multiply 16*-4 to get -64
Hope this helps
Answer:
<u>5/4</u>
Step-by-step explanation:
Given :
- tanθ = 3/4 = opposite/adjacent
Finding the missing side :
- The hypotenuse must be found
- √3² + 4²
- √25
- 5
Taking the sec ratio :
- secθ = hypotenuse/opposite
- secθ = <u>5/4</u>

Given:
A figure of dilation and the center of dilation is O.
To find:
The value of y.
Solution:
The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).



Where, k is the scale factor or constant of proportionality.
So, the scale factor for the given dilation is



We know that,




Divide both sides by 9.



Therefore, the value of y is 12.
Given
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.
The sandwich cost $7.75 and sales tax was $0.47.
Find out the cost of her drink
To proof
Let the cost of her drink be x.
As given in the question
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.
Elysse paid for her sandwich and drink = 10 - 0.63
= $ 9.37
sandwich cost $7.75 and sales tax was $0.47
Than the equation becomes
x = 9.37 - (7.75 + 0.47)
x = 9.37 - 8.22
x = $ 1.15
The cost of the drink is $ 1.15.
Hence proved
