Answer:0,3 and 3,0
Step-by-step explanation:
0,3 and 3,0 are right because we need 0 and 3 to be one the X side
1,0 and -1,3 is wrong it is not a 1 or -1
2,0 and 2,0 is wrong because it is not 2 on x axis
-1,0 and -1,-3 are wrong because we are not on -1 on x axis
hopefully i explained it right
Answer:
Step-by-step explanation:
<u>Using the the equation </u>
<u>The ball hits the ground, when h = 0, solving below equation:</u>
- 100t − 16t^2 = 0
- 4t(25 - 4t) = 0
- t = 0 seconds, this is the starting point when ball was hit
- 25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground
Answer:
given p(x)= 5x^3-7x^2-ax-28
(x-4) is a factor of 5x^3-7x^2-ax-28
=>p(4)=0
=>5(4)^3-7(4)^2-4a-28=0
=>320-112-4a-28=0
=>-4a=-180
=>a=180/4
=>a=45
Step-by-step explanation:
x=a
SOH CAH TOA tells you the sine ratio is
Sin = Opposite/Hypotenuse
sin(x) = 12.5/15
Then the angle x can be found using the inverse function.
x = arcsin(12.5/15) ≈ 56°
The appropriate choice is
b) 56
