Answer:

y =  ( x − 2 ) ^ 2 + 3

y =   x^2 − 4x + 7

Step-by-step explanation:

y = a ( x − h ) ^ 2 + k

where vertex is (h,k) = (4,-1)

h=4, k=-1

y = a ( x − 4 ) ^ 2 - 1

sub ( 2,3 )

3 = a (2 - 4)^2 - 1

a=1

y = 1 ( x − 2 ) ^ 2 + 3

y =  ( x^2 − 4x + 4 )  + 3

y =   x^2 − 4x + 7

For the given triangles select the lengths of the sides.
aivan3 [116]

Answer:

v=3

u=6

x=2√2

y=2√2

Step-by-step explanation:

First triangle :

tanΦ=v/3√3

tan30=v/3√3

(√3)/3=v/(3√3)

Cross multiply

(√3)/3 x 3√3=v

(√3 x 3√3)/3=v

(3√9)/3=v

(3x3)/3=v

9/3=v

3=v

v=3

Sin30=v/u

0.5=3/u

Cross multiply

0.5xu=3

0.5u=3

Divide both sides by 0.5

0.5u/0.5=3/0.5

u=6

Second triangle :

sin45=x/4

Cross multiply

x=4 x sin45

x=4 x (√2)/2

x=2√2

Cos45=y/4

Cross multiply

4 x Cos45=y

4 x (√2)/2=y

(4√2)/2=y

2√2=y

y=2√2

Mr brown shares with the class that 70%of the students got a A on the English vocabulary quiz if mr brown has 100 students creat
Harrizon [31]
70% of 100 is 70 students. Unfortunately I can not make a model for you but here's an idea: Draw a large circle. Next, draw a line halfway down the circle, and halfwar down draw another line to the right, this making it look like three fourths. Then, color the larger space in one color and the other smaller space that looks like a small slice of pie in another color. On the larger piece write "70% who got an A" and on the smaller write "30% who didn't get an A" At the bottom you can write 70 students out of 100 got an A on the test.
