Answer:
32.8 feet
Step-by-step explanation:
1 meter = 3.28084 feet
10 x 3.28084 = 32.8084
which rounds to <u><em>32.8</em></u>
1 foot=12 inches
Divide 12 from 156.
156÷12=13
Janna jumped 13 feet in the long jump competition, which is actually really good!
Answer:
-5
Step-by-step explanation:
-15/3=-5
We know that the points at which the parabola intersects the x axis are
(-5,0) and (1,0)
So the extent between these two points would be the base of the triangle
lets find the length of the base using the distance formula
![\sqrt{[(-5-1)^{2}+(0-0)^{2} ]}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%5B%28-5-1%29%5E%7B2%7D%2B%280-0%29%5E%7B2%7D%20%5D%7D%20%20)
the base b=6
We will get the height of the triangle when we put x=0 in the equation
y=a(0+5)(0-1)
y=-5a
so height = -5a (we take +5a since it is the height)
We know that the area of the triangle =
× 6 × (5a) = 12
15a=12
a= 
12:5 is what you are looking for. 12/5 in fraction form
