Answer:
In order to solve this non-linear equation, we need to move all the terms to the left side.
In our example,
- term , will be moved to the left side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
We need to get rid of expression parentheses.
If there is a negative sign in front of it, each term within the expression changes sign.
Otherwise, the expression remains unchanged.
In our example, there are no negative expressions.

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

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

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.

A sphere and a cylinder have the same radius and height the volume of the cylinder is 48cm what is the volume of the sphere
Answer:
Step-by-step explanation:
Since they have the same height, the h of the cylinder must be 2r like the sphere.
[tex]V_c=h\pi r^2,\ given\ h=2r,\ V_c=2\pi r^3,\ 2\pi r^3=48,\ r^3=\frac{24}{\pi}\\ \\ V_s=\frac{4\pi r^3}{3},\ V_s=32 cm^3[/tex]

A survey is conducted to determine the percentage of students at state universities who change their major at least once. In a SRS of 100 students 78% indicated that they graduated with a major different from the one with which they entered college. Determine a 95% confidence interval for the percentage of students who change their major.
Answer:
95% confidence interval for the percentage of students who change their major
(0.69881 , 0.86119)
Step-by-step explanation:
Step(i):-
Given that the sample size 'n' = 100
Given that the sample proprtion
p = 78% = 0.78
Level of significance =0.05
Critical value Z₀.₀₅ = 1.96
Step(ii):-
The 95% of confidence interval is determined by
[tex](p^{-} -Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } , p^{-} +Z_{0.05} \frac{\sqrt{p(1-p)} )}{\sqrt{n} })[/tex]
[tex](0.78 - 1.96 \frac{\sqrt{0.78(1-0.78)} }{\sqrt{100} } , 0.78 +1.96 \frac{\sqrt{0.78(1-0.78} )}{\sqrt{100} })[/tex]
(0.78 - 0.08119,0.78 + 0.08119 )
(0.69881 , 0.86119)
Final answer:-
95% confidence interval for the percentage of students who change their major
(0.69881 , 0.86119)
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.

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

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%
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

Please help this question finding a side on a triangle
Answer:
The side of the hypotenuse is 12.233 centimeters.
Step-by-step explanation:
The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:
[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)
Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.
Then, we clear the variable within (1):
[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]
[tex]x = 13.233\,cm[/tex]
The side of the hypotenuse is 12.233 centimeters.
