X=7
So 86 is your angle
(The right one)
Answer: B
Step-by-step explanation:
The slope-intercept is usually written as y = mx + b form, where m is the slope, and b is the y-intercept. The y-intercept is the y value when x is equal to 0.
We can first eliminate C, because the y-intercept of the graph is 1.
To solve for slope, which is the m, choose two points, (-1, 5) and (1, -3).
Slope = (y2 - y1) / (x2 - x1)
= (-3 - 5) / (1 - (-1))
= (-3 - 5) / (1 + 1)
= -8/2
= -4
Plug in the slope and y-intercept, we get y = -4x + 1
Answer:
C
(5,7)
Step-by-step explanation:
y = a(x - 3)^2 + 2 The second point solves for a
x = 1
y = 7
7 = a(1 - 3)^2 + 2
7 = a(-2)^2 + 2 Subtract 2 from both sides
7-2 = a*4 +2 - 2
5 = 4a
a = 5/4
=========
y = 5/4 (x - 3)^2 + 2
B isn't going to work. x - 3 reduces to 0. There is no way that y = 7 out of that.
The x value - 3 must be divisible by 4 because the answers are all integers. Try C.
y = 5/4 (5 - 3)^2 + 2
y = 5/4 (2)^2 + 2
y = 5/4 (4) + 2
y = 5 + 2
y = 7
So the other point is 5,7
Answer:
Step-by-step explanation:
h and r are the height and radius of the tank, respectively.
volume = πr²h
πr²·9 = 572π
r = √(572π/(9π)) = √(572/9)
diameter = 2r ≅ 15.9 ft
