Answer:
[tex]Rate = -15[/tex]
Step-by-step explanation:
Given
[tex]H(x) = -2x^2 - 3x - 1[/tex]
[tex][a,b] = [1,5][/tex]
Required
The average rate of change
This is calculated using:
[tex]Rate = \frac{H(b) - H(a)}{b - a}[/tex]
Substitute values for a and b
[tex]Rate = \frac{H(5) - H(1)}{5 - 1}[/tex]
[tex]Rate = \frac{H(5) - H(1)}{4}[/tex]
Solve for H(5) and H(1)
[tex]H(5) = -2*5^2 - 3*5 - 1 = -66[/tex]
[tex]H(1) = -2*1^2 - 3*1 - 1 = -6[/tex]
So, the expression becomes:
[tex]Rate = \frac{-66 - (-6)}{4}[/tex]
[tex]Rate = \frac{-66 + 6}{4}[/tex]
[tex]Rate = \frac{-60}{4}[/tex]
[tex]Rate = -15[/tex]
What is the equation for y= and The high of the basketball after 1.7 second? Please explain your answer.
Answer:
Step-by-step explanation:
ax² + bx + c = y
Plug in data points to get a system of equations in three unknowns.
(0.5,18): 0.25a + 0.5b + c = 18
(1,24): a + b + c = 24
(1.5,22): 2.25a + 1.5b + c = 22
Solving the system: a = -16, b = 36, c = 4
y = -16x² + 36x + 4
When x = 1.7, y = -16·1.7² + 36·1.7 + 4 = 18.96 ft

Christine has her own dog-walking business. She charges her customers $20 per day to walk their dog.
Make a table to show how much she earns for walking 1 to 8 dogs.
Please help me !
Answer:
Number of dogs (x) | Amount charged to walk a dog (y)
1 | 20
2 | 40
3 | 60
4 | 80
5 | 100
6 | 120
7 | 140
8 | 160
Step-by-step explanation:
Charge for walking a dog = $20 per dog
Number of dogs = x
Amount charged to walk a dog in a day = y
Unit rate = 20
Equation to represent this is: y = 20x
Let's use this to form a table for walking 1 to 8 dogs:
For 1 dog (x):
y = 20(1) = $20
For 2 dogs (x):
y = 20(2) = $40
For 3 dogs(x):
y = 20(3) = $60
For 4 dogs:
y = 20(4) = $80
And so on till we get to tl8 dogs.
This, we should have the following table:
Number of dogs (x) | Amount charged to walk a dog (y)
1 | 20
2 | 40
3 | 60
4 | 80
5 | 100
6 | 120
7 | 140
8 | 160

Does any one know the answer
Answer:
Step-by-step explanation:
Solve for x=0 and x=1
y(0)=2(3^0)=2(1)=2 so (0,2) is a point.
y(1)=2(3^1)=2(3)=6 so (1,6) is a point.
Only graph B has those two points.

Answer:
B
Step-by-step explanation:
So for the first square we Have ab*a
When you multiply variables then you add up their powers so b^1a^1+a^1= (a^2)(b^1)
Second box is -3 * a which is equal to -3a
third box is 2b * ab = 2ab^2
fourth box is -3 *2b = -6b

Select the correct answer from the drop-down menu.
A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as
x+2x+6 < 50, where x represents the smaller number.
From the set {13, 14, 15, 16, 17), the values of x for which the inequality holds true are
Reset
Next
Answer:
13 and 14
Step-by-step explanation:
From the inequality
x + 2 x + 6 < 50
we work out the answer for x isolating it on one side of the inequality as shown below
3 x + 6 < 50
3 x < 50 - 6
3 x < 44
x < 44/3 ≅ 14.6666...
Therefore, select from the set the numbers: 13 and 14.

A cone has a volume of 33 cubic inches. If a cylinder has the same height and the same radius as the cone, what is the volume of the cylinder?
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
The volume of a cylinder = πr²h
= 33 cubic inches
The volume of a cone = ¹/3 πr²h
If the cylinder and come share the same radius and height then ‘πr²h’ part of the formulas is the same for both;
It means the difference in proportionality is ¹/3 (because even π is the same across board). The volume of the cone is therefore;
¹/3 (33)
= 11
= 11 cubic inches

33.85 or 32.75 sorry if I am wrong
Step-by-step explanation:
for this one you have you multiply 17 by itself like this 17x17=289 but you also have to do it with the 28 to like this 28x28=784, now what you do it add up the 289+784=1,073 then you square root 1,073 which gives you 32.75 round it to the nearest tenth of needed so your will be between 33.85 or 32.75

in a sequence, each
term after the first is the sum of the squares of the
digits of the previous term. Thus if the first term
were 12, the second term would be 12 + 22 = 5, the
third term 52 = 25, the fourth term 22 + 52 = 29, and
so on.
Find the first five terms of the sequence whose first
term is 25.
?
Answer:
25 , 29, 85 , 89 , 145 , 42.
Step-by-step explanation:
The first five terms will be 25, 29, 85, 89, 145.
What is a sequence?A sequence is defined as an arrangement of numbers in a particular order.
Given that, in a sequence, each term after the first is the sum of the squares of the digits of the previous term.
The first term is 25
Therefore, according to question,
2nd term = 2²+5² = 4+25 = 29
3rd term = 2²+9² = 4+81 = 85
4th term = 8²+5² = 64+25 = 89
5th term = 8²+9² = 64+81 = 145
Hence, The first five terms will be 25, 29, 85, 89, 145.

The ratio of the measures of the sides of a triangle is 3:5:7, and its perimeter is 135 feet. Find the measure of each side of the triangle.
a. x = 9
b. 13.5 ft, 22.5 ft, 31.5 ft
c. 27 ft, 45 ft, 63 ft
d. 25 ft, 45 ft, 65 ft
Answer:
The correct answer is C. 27 ft, 45 ft, 63 ft.
Step-by-step explanation:
Given that the ratio of the measures of the sides of a triangle is 3: 5: 7, and its perimeter is 135 feet, in order to find the measure of each side of the triangle, the following calculation must be performed:
3 + 5 + 7 = 15
135/15 = 9
9 x 3 = 27
9 x 5 = 45
9 x 7 = 63
Therefore, the measures of the sides of the triangle are 27 ft, 45 ft, and 63 ft.

About 182 out of 200 students prefer walking instead of riding the bus to school. About what percent of the students prefer walking?
Answer:
81%
Step-by-step explanation:
Total student = 200
Student that prefer walking = 182
Percent of those that prefer walking = student that prefer walking/total student * 100
Percent of those that prefer walking = 182/200 * 100
Percent of those that prefer walking = 182/2
Percent of those that prefer walking = 81%
Hence the required percentage is 81%
