Answer:
Step-by-step explanation:
hello :
an equation of this graph is : f(x) = a(x-h)²+k when (h,k) the vertex
so : h=5 and k= -4
f(x) = a(x-5)²-4....... now calculate : a
the y- intercept is : - 6.5 means : f(0) = - 6.5
put x=0 and f(x) = - 6.5
you have : -6.5 = a(0-5)²-4
-6.5 = 25a - 4
25a = -2.5 so : a= -2.5/25= 1/10
the equation is :
<h2>f(x) = (1/10)(x-5)²-4</h2>
Answer:
Step-by-step explanation:
49.4 degrees
Step-by-step explanation:
In Triangle AXY,
We want to determine the angle of elevation from the point is standing to the top of the flagpole, which is the angle at V in the diagram.
In Triangle XVY
|VY|=36 feet
Therefore, the angle of elevation from the point is standing to the top of the flagpole is 49.4 degree to the nearest tenth of a degree.
I think i might of clicked on gthe wrong question sorry
Answer: Kim got 13 questions wrong.
Step-by-step explanation: First find how many questions were 75% of 52 questions since 3/4 is equal to 75%. Then subtract that amount (which is 39) from 52 and you get 13.
