The function h(x) = –2x2 + 8x written in vertex form is h(x) = –2(x – 2)2 + 8. The function h(x) is shown on the graph along wit

h the parent function, f(x) = x2. Which statement is true concerning the vertex and axis of symmetry of h(x)? The vertex is at (0, 0) and the axis of symmetry is x = 2. The vertex is at (0, 0) and the axis of symmetry is y= 2. The vertex is at (2, 8) and the axis of symmetry is x = 2. The vertex is at (2, 2) and the axis of symmetry is y = 2.

If the beginning temperature was -13 degrees at 5:00 a.m. what was the temperature at 9:00 a.m
Aleks04 [339]

<u><em>Answer:</em></u>

-23.4 at 9:00 a.m.

<u><em>Step-by-step explanation:</em></u>

Make a ratio with the given numbers: -13, 5.

I believe the "common number" for the ratio of 1 a.m. would be:

2.6<u> : </u>1 times 9 = 23.4<u> </u><u>:</u><u> </u>9

The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by
creativ13 [48]

The average rate of change of h over the interval is -48 feet per second.

Given,

The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by

h(t) = −16t2 + 96t, 0 ≤ t ≤ 6.

We need to find the average rate of change of h over the interval [3, 6].

<h3>How do we find the average rate of change of a function over an interval?</h3>

If we have an interval [a, b] and a function f(x).

The rate of change is given by:

= f(b) - f(a) / b - a

We have,

h(t) = −16t² + 96t and [3, 6].

h(6) = -16 x 6² + 96 x 6 = -576 + 576 = 0

h(3) =  -16 x 3² + 96 x 3 = -144 + 288 = 144

The average rate of change of h is:

= h(6) - h(3) / 6 - 3

= 0 - 144 / 3

= -144 / 3

= -48

Thus the average rate of change of h over the interval is -48 feet per second.

A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in.
Firdavs [7]
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.

Divide the area of the combined areas and the total area to find the probability of landing on a triangle.

A = 1/2bh
      1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)

A = bh
     26 x 26
A = 676 square inches

128/676 = 0.189

There is an approximate probability of 0.19 of hitting a triangle.

To manage a rental property, a property manager charges $65 per month plus 6% of the rent.
Igoryamba

Given parameters:

Charge per month  = $65

Percentage on rent= 6%

Amount paid by Jack per month = $164

Unknown:

Monthly rent on his property = ?

Solution:

  Monthly rent on his property can be found by;

  Amount paid by Jack per month = Charge per month + 6% of monthly rent

Let the monthly rent = x ;

  So;

              164  = 65 + \frac{6}{100}  x x

              164 - 65  = \frac{6x}{100}

                   99  = \frac{6x}{100}

                   6x = 9900

                    x = 1650

Monthly rent on his property is $1650
