Create an expression with at least 10 terms that would simplify to 5x^ 3 +9x^ 2 -x-6 Try to create something different than what others have created.♀️
Answer:
-x^3 + 2x^3+ 4x^3 + 3x^2 + 7x^2-x^2-9x + 8x-5-1
Step-by-step explanation:
Here, we want to have an expression of at least ten terms which when simplified would give polynomial
We have the expression as
x^3 - 2x^3+ 4x^3 + 3x^2 + 7x^2-x^2+ 2x^2-9x + 8x-5-1
if the daimeter of a solid cylinder with lenght 140cm is 8cm , find its curved surface area ,
Answer : The curved surface area of solid cylinder is [tex]3520cm^2[/tex]
Step-by-step explanation :
As we are given that:
Diameter of solid cylinder = 8 cm
Length or Height o solid cylinder = 140 cm
Formula used to calculate the curved surface area of cylinder is:
Curved surface area of cylinder = [tex]2\pi r\times h[/tex]
where,
r = radius of cylinder
h = height or length of cylinder
Radius of cylinder = [tex]\frac{Diameter}{2}=\frac{8cm}{2}=4cm[/tex]
Now putting all the given values in above formula, we get:
Curved surface area of cylinder = [tex]2\times \frac{22}{7}\times 4cm\times 140cm[/tex]
Curved surface area of cylinder = [tex]3520cm^2[/tex]
Therefore, the curved surface area of solid cylinder is [tex]3520cm^2[/tex]
Given:
Diameter of a solid cylinder = 8cm
Length (height) of cylinder = 140 cm
To find:
The curved surface area of the cylinder.
Solution:
We have,
Diameter = 8cm
Radius = [tex]\dfrac{8}{2}=4\text{ cm}[/tex]
Height = 140 cm
Curved surface area of a cylinder is
[tex]CSA=2\pi rh[/tex]
where, r is radius and h is height.
Putting r=4 and h=140 in the above formula, we get
[tex]CSA=2\times \dfrac{22}{7}\times 4\times 140[/tex]
[tex]CSA=2\times 22\times 4\times 20[/tex]
[tex]CSA=3520[/tex]
Therefore, the curved surface area of the cylinder is 3520 square cm.
Which shaded region is larger? Explain your reasoning..
Answer:
It's B because If you cover the blue you will see space that looks like a triangle. Do the same to A. You see how in B the Triangle looking thing is lower than A because A triangle thing is like more up and wider so it has space. Also B has a little space than A
Step-by-step explanation:
Tom earns £10 an hour and his wife earns £2 an hour more than Tom. Write a formula for their total earnings T for h hours.
Answer:
The formula for total earning is T = £22h
Step-by-step explanation:
Given that:
Per hour earning of Tom = £10
Per hour earning of Tom's wife = £10 + £2 = £12
Let,
T represent their total earnings
h be the number of hours
Total earnings = (Tom's per hour earning + His wife's per hour earning) * Number of hours
T = (£10+£12)h
T = £22h
Hence,
The formula for total earning is T = £22h

If a triangle has 2 sides of 8 and 11 what could the third side be
Answer:
Any value between 3 and 19 may be the measure of third side.
Step-by-step explanation:
If three sides of a triangle are a, b, and c, possible measures of the sides of a triangle will be.
1). a + b > c
2). b + c > a
3). a + c > b
If a = 8, b = 11,
1). 8 + 11 > c
c < 19
2). 11 + c > 8
c > 8 - 11
c > (-3)
3). 8 + c > 11
c > 11 - 8
c > 3
Therefore, by combining the given inequalities,
3 < c < 19
Any value between 3 and 19 may be the measure of third side.
What is the slope and y-intercept of the following equation: f(x) = 2x - 5
Answer:
slope- 2
y int- -5
Step-by-step explanation:
A student performed the following steps to find the solution to the equation
X2 - 2x - 8 = 0. Where did the student go wrong?
Step 1. Factor the polynomial into (x - 4) and (x - 2)
Step 2. X-4 = 0 and x - 2 = 0
Step 3. x = 4 and x = 2
A. in Step 2
B. in Step 1
C. The student did not make any mistakes, the solution is correct
D. in Step 3
Answer:(b) step 1
Step-by-step explanation:
The wrong step in the student's workings is step 1
How to determine the wrong step?The equation is given as:
x^2 - 2x - 8 = 0
Expand the equation
x^2 + 2x - 4x - 8 = 0
Factorize the equation
x(x + 2)- 4(x + 2)
Factor out x + 2
(x - 4)(x + 2) = 0
The above means that the factored equation of x^2 - 2x - 8 = 0 is (x - 4)(x + 2) = 0
This means that the step 1 of the student's step is wrong and incorrect

State the degree and end behavior of the following polynomial f(x)=4x^3+3x^5-x^2 - 2
Answer:
Degree
Five Degree
End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Step-by-step explanation:
[tex]y = 4 {x}^{3} + 3 {x}^{5} - {x}^{2} - 2[/tex]
A five-degree polynomial function. Rearrange the terms.
[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]
Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.
Graph / End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.

Find Value of y.
=====================================
Work Shown:
EI = EG
3y-10 = 2y
3y-10-2y = 0
y-10 = 0
y = 0+10
y = 10
Note how if y = 10, then
EI = 3y-10 = 3*10-10 = 20EG = 2y = 2*10 = 20Both EI and EG are 20 units long when y = 10. This confirms the answer.

I think it might be e=5h someone please correct me if I'm wrong
Step-by-step explanation:
Answer:
e = 5h
Step-by-step explanation:
To find the unit rate (money earned per hour), we divide 10 by 2, which gets us 5. That means $5 is earned per house. If h is the number of houses shoveled, and he earns $5 per house, we can write that as 5h. If e is the money earned, we can write this whole thing as e = 5h.

What is the value of x in the solution to the system of equations below?
15x - 12y = 13
30x + 9y = 4
Answer:
1/3
Step-by-step explanation:
Use the elimination method.
15x - 12y = 13
30x + 9y = 4
If you add both equations you will not cancel out any variables, so you need to multiply one of the equations by something. Multiply the first equation by -2 to cancel out the x values.
-2(15x - 12y = 13)
30x + 9y = 4
You should have these two equations now:
-30x + 24y = -26
30x + 9y = 4
Add them together now. You should get this now.
33y = -22
Divide both sides by 33. You should get y = -2/3
Now, substitute the y value into any of the two equations that you started with. Let's substitute the y value for the second equation.
30x + 9 (-2/3) = 4
30x - 6 = 4
30x = 10
30 30 (divide 30 and 10 by 30)
x = 1/3

Step-by-step explanation:
25 is the length of the hypotenuse side and 14 is the length of the opposite side.
Therefore, you will need to use sine to work out the missing angle.
