His average is 80%. You take the two scores add them up and divide by the number of scores.
To vertically strech a function, f(x) by a factor of c, that is cf(x)
so strech vertically by 2 means times whole thing by 2
so
2 times (4x^2-5) =8x^2-10
g(x)=8x^2-10
Answer:
A=2*(t-1)-500
Step-by-step explanation:
I did it on study island.
The slope of the line is 6/2 because if you start at the first point you go over 6 in the x direction (right) and then you have to go up in the y direction (up)
Answer:
A=672 m²
Step-by-step explanation:
a²+b²=c² (to find h)
14²+b²=50²
196+b²=2,500
b²=2,304
√b²=√2,304
b=48
h=48
(base×height)÷2
(28×48)÷2
1,344÷2
A=672 m²
