Answer:
27
Step-by-step explanation:
9³÷3³=729÷27
= 27
(-2, -1) so y = <span>-2(-2) + 3 = 7; FALSE
</span>(3, 3) so y = -2(3) + 3 = -3; FALSE<span>
(3, -3) </span>so y = -2(3) + 3 = -3; TRUE<span>
(-3, -9) </span>so y = -2(-3) + 3 = 9; FALSE
answer
<span>(3, -3)</span>
Answer:
Step-by-step explanation:
Given that Elijah threw a ball from a height of 4 feet. The ball reached maximum height of 16 feet after 2seconds
Let vertical component of his speed be v
When it reaches maximum height its velocity becomes 0
Hence
height reached by the ball =
When h=12(16-4) we get g=gravity =32
Hence 12 =2v-16(4)
v=38
Hence 
where h is calculated from the height of hand i.e. 4 feet
When it touches the ground h =-4
When it starts falling then distance travelled = 16 feet
Initial velocity =0 Accn due to gracity =32 feet
Using these we can write
So after 3 minutes from start the ball would reach the ground
Sketch a graph so you can find the vertex and determine if the parabola is horizontal or vertical. When i graph (-2,4) and then y=6, I find the middle is (-2,5) so that will be the vertex. The distance to the vertex is -1 so 4p=-4.
My formula is (x-h)^2=4p(y-k), now just plug in numbers. You should end up with (x+2)^2=-4(y-5).
Some instructors want you to write (y-k)=1/(4p)(x-h)^2 which is the same thing, so check to see which one you should be using.
Answer:
6 : 2
Step-by-step explanation:
30 : 10
( 30 divided by 5 equals 6)
( 10 divided by 5 equals 2)
ratio is:
6 : 2
pls mark brainlest ;)
Hopefully this helps you :)
