Answer:

t=10.9

Step-by-step explanation:

8t-13t+10(t-2)=34

8t-13t+10t-20=34

5t-20=34

5t=54

t=10.9

Answer:

The rocket's maximum height will be 1424 feet.

It will reach that height in 4 seconds.

It will reach the ground  in 8 seconds.

Step-by-step explanation:

One easy way to find the peak is to find the derivative and solve for zero:

h(t) = -16t² + 128t + 1680

To find the derivative of each term in that format, you simply multiply the coefficient by the exponent, and reduce the exponent by one.  In the case of terms with no variable, they disappear.  That gives us:

h'(t) = -32t + 128

This derivative describes the rate of change of h with respect to t, so to find the peak, we simply need to solve it for zero:

0 = -32t + 128

32t = 128

t = 4

So the maximum height occurs when t = 4.  Let's plug it in to the original equation:

h(t) = -16t² + 128t + 1680

h(4) = -256 + 512 + 1680

h(4) = 1424

So the rocket's maxiumum height is 1424 feet.

And we've already answered the second question, it happens at 4 seconds.

Also, the amount of time going up will be the same as the amount of time going down, which means that it will reach the ground in twice that time, or 8 seconds.

ANSWER FOR A BUNCH OF POINTS !!EASY!!
Tasya [4]

The correct option is D for the placement of regular polygon and the rhombus.

<h3>What is defined as the regular polygon?</h3>
  • A polygon is a two-dimensional enclosed image created by connecting three or more straight lines.
  • A rhombus is a special parallelogram because it meets the definition of a parallelogram, which is a quadrilateral to two pairs of parallel sides.
  • A polygon is made up of three parts:
  1. Sides: A side is a line segment that connects two vertices.
  2. Vertices: A vertex is the point where two sides meet.
  3. Interior and exterior angles An interior angle is an angle formed by joining the sides of a polygon within its enclosed surface.

As, all the given figures comes under the regular polygon, all are placed in the left circle.

But the three diagram in white, orange and blue colour are regular polygon along with rhombus.

Thus, all three are placed in the intersection of the both circle of the vein diagram.
