Answer:
972 u³
Step-by-step explanation:
The radius is 9 . We can use formula ,
⇒ V = 4/3 π r³
⇒ V = 4/3 × π × 9³
⇒ V = 4 × π × 81 × 3
⇒ V = 972 unit³
Answer:
Step-by-step explanation:
2(2x+7) = 6x-8
4x + 14 = 6x - 8
2x = 22
x = 11
m<XYZ = 58
m<XYW = 29
Answer:
UV = 4.5 (not rounded)
TV = 3√3
m∠U = 60˚
Step-by-step explanation:
UV = Use sin function since you’re finding the hypotenuse with a given angle and opposite side.
sin(30) = 9/UV
9sin(30) = UV
4.5 = UV
TV = Use Tangent function (opp. over adj.) since you’re finding the adjacent side with a given angle and opposite side.
tan(30) = 9/TV
9tan(30) = TV
3√3 = TV
m∠U = Sum of all interior angles of a triangle is 180˚:
90˚ + 30˚ = 120˚
180˚ - 120˚ = 60˚
Hope this helps :)
Answer:
No solution
Step-by-step explanation:
There is no option good for the two graphs.
I think simple vertical stretch or simple vertical compression will occur at the same side of axis, but |x| located at quadrant I and II while -1/2|x| located at quadrant III and IV.
The answer should be "reflect over the x axis and then vertical stretch"
Answer:
x=0, y=-2
Step-by-step explanation:
Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:
-7x + 9y = -18
-(4x + 9y = -18)
__________
-11x = 0
x = 0
Since we know x=0, then we plug it back into one of the equations to get the value of y:
-7x + 9y = -18
-7(0) + 9y = -18
0 + 9y = -18
9y = -18
y = -2
Therefore, x=0, and y=-2
