The height, in feet, of an arrow shot from a bow in an upwards direction, is modeled by the function h(t) = -16t2 + 96t + 5, whe

AnnZ [28]

Given function: h(t) = -16t^2 + 96t + 5, where t represents the time in minutes.

We need to find the interval for which the arrow is going up.

The arrow is going up would be the values of time t =0 when it start and when it went to highest point.

Given function is a quadratic function and it represents a parabolic shape.

The highest point on the parabola is a vertex point.

Therefore, we need to find the x-coordinate of the vertex.

We know, formula for x-coordinate of the vertex is

$\frac{-b}{2a}$

For the given quadratic a= -16 and b=96.

Plugging values of a and b in formula, we get

$\frac{-96}{2(-16)}=\frac{-96}{-32} = 3.$

Therefore, after 3 seconds arrow would be at maximum height.

Therefore, the interval for which the arrow is going up is [0,3].

140% of what number is 35?

Elodia [21]

In order to solve this, all you have to do is divide 35 by 1.4 (because you need to move the decimal places over to the left two places when changing from a percentage to a decimal.) When you do that, you get 25, so 35 is 140% of 25. I hope this helps! :)

What is 2y+x=-6 and y=-2x+0 using substitution method?

vazorg [7]

2y + x = -6
y = -2x + 0

We can substitute the second equation into the first one.

2y + x = -6
2(-2x + 0) + x = -6
-4x + x = -6
-3x = -6

Divide -3 on both sides.

x = 2

Now, plug x = 2 into any equation and solve for y.

y = -2x + 0
y = -2(2) + 0
y = -4

The solution to the system of equations is (2,-4).
