Answer:
C
Step-by-step explanation:
Since the lines are parallel then
x and 120 are alternate angles and congruent, hence
x = 120 → C
Okay <em>we need to know the number of degrees in this shape first</em> in order to find x.
The formula to find the # of degrees in any polygon is
180 ( n - 2 )
n = the number of sides the figure has
This figure has 8 sides
180 ( 8 - 2 )
180 (6) = 1080°
This figure is 1080°
To find x, let's <u>subtract all the other degrees</u> they gave us
<em>1080° - 124° - 136° - 132° - 129° - 116° - 158° - 141° = 144°</em>
x = 144°
I hope I helped!
Answer:
10. (5,-10) and (2,-4)
11. The maximum height of the ball is 16 feet and it occurs 1 second after the ball is kicked.
Step-by-step explanation:
11. f(x)=-16x^2+32x
0=-16x^2+32x
0=x^2-2x
0=x(x-2)
f(x)=-16^2+32x
f(x)=-16 X (1)^2+32 X (1)
= -16+32
=16
Answer:
3rd option
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x - 4)² + 3 ← is in vertex form
with vertex = (4, 3 )
• if a > 0 then vertex is minimum
• if a < 0 then vertex is maximum
here a = - 2 < 0
then vertex (4, 3 ) : maximum
Answer:
96
Step-by-step explanation:
Write out:
(X-2)/3=30
Then add 2 to both sides:
x/3=32
Then multiply both sides by 3:
x=96
