Y-intercept is (0,-7) x-intercept is (14,0)
Answer:
Dilation changes (x,y) values not the grid or coordinate plane. Basically, dilating a graph or a coordinate grid means the original coordinates you may have had will be changed with the dilation. For example, a triangle plotted had its original area of 26 dilated to an area of 58.
Answer:
the answer is $50 for the full price of the sweater
Step-by-step explanation:
if you know $20 is 40% what is 20% it is $10 and then multiple it by 5 because 20 times 5 is 100 and you get 50
Answer:
BC = 17.2.
Step-by-step explanation:
Since CAB = 90º, this is a right triangle.
The triangle format is given below:
C
A B
We have that AB = 8.6, and angle B measures 60º.
Length of BC:
BC is the hypotenyse.
Side AB is adjacent to angle B = 60º.
In a right triangle, angle
, it's adjacent side with length s and the hypotenuse h are related by the cosine of the angle, that is:
![\cos{\alpha} = \frac{s}{h}](https://tex.z-dn.net/?f=%5Ccos%7B%5Calpha%7D%20%3D%20%5Cfrac%7Bs%7D%7Bh%7D)
In this question, we have an angle of 60º, with has cosine 0.5. We also have that side AB = s = 8.6, and the hypotenuse h is side BC. So
![\cos{\alpha} = \frac{s}{h}](https://tex.z-dn.net/?f=%5Ccos%7B%5Calpha%7D%20%3D%20%5Cfrac%7Bs%7D%7Bh%7D)
![0.5 = \frac{8.6}{h}](https://tex.z-dn.net/?f=0.5%20%3D%20%5Cfrac%7B8.6%7D%7Bh%7D)
![0.5h = 8.6](https://tex.z-dn.net/?f=0.5h%20%3D%208.6)
![h = \frac{8.6}{0.5}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B8.6%7D%7B0.5%7D)
![h = 17.2](https://tex.z-dn.net/?f=h%20%3D%2017.2)
BC = 17.2.
