Y=4x²-7x+13
y-13=4(x²-(7/4)x)
y-13+4*(7/8)²=4(x²-2*(7/8)x+(7/8)²)

y-13+4*(7/8)²=4(x-(7/8))²
y-13+ 3.0625=4(x-0.875)²
y-9.9375=4(x-0.875)²
y=4(x-0.875)² +9.9375

To convert 70 minutes to seconds, you would use the ratio .

garri49 [273]

1:60 because there is 60 seconds in 1 minute, so you'd have 70/x=1/60 and then you would cross multiply

I can't find x y or z

Sholpan [36]

Answer:

x = 4 $\sqrt{3}$

y = 6

z = 8

Step-by-step explanation:

keep in mind I'm not doing that well with geometry so this might all be wrong lol

x is part of a 30 60 90 triangle.

so x is 4 $\sqrt{3}$

next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.

4 + 6 = 10

10^2 = 100

100 = a^2 + b^2

y = 6 and z = 8 bc 36 + 64 = 100
