Answer:
Angle at the center is two times the angle at circumferance
guys please help......................................................
Answer:
angles A+ 100 + B are supplementry and add up to 180 degress. Angle A and 20 degree angle are congruent, so angle A is 20 degrees. Angle B and 60 degrees are congruent so B is 60 degrees. Angle C and 100 degrees are congruent so C is 100 degrees.

Question 6 of 10
f(x) = 5x + 1) – 3
g(x) = 4
Find (f - g)(x).
Answer:
Answer:
5x + 6
Step-by-step explanation:
(f-g)(x) is nothing but f(x) - g(x)
f(x) is |5x + 1| - 3 and g(x) is 4 so the equation is [|5x+1| - 3] - [4]
Once this is solved, the answer is 5x - 6. Since there's absolute value, remove the negative and change it to a positive to get the answer 5x + 6.

logan gets paid 18 $ to sweep the house logan gets paid 3 times as much to sweep the house as he does to clean the bathroom how much does logan get paid to clean the bathroom
Answer:
6
Step-by-step explanation:
tell me if I'm wrong:
b-bathroom
s-sweep
《in equation form》
s×3=18
18/3=6
so s=6
《explanation》
^ so you are going to divide 18 by 3 which gives you the answer 6^
A newspaper publisher wants to check its daily output of about 300,000 newspapers to be sure each includes a comics section. Explain how the publisher could do this. IN YOUR OWN WORD ASAP AND Giving Brainly
Answer:
Step-by-step explanation:
Number of Newspaper Published in a day = 300,000
Each news paper must include a Comic section. To check whether each newspaper has comic section or not, the publisher must make a sample Size of 500 or 1,000 will be good . That is , the publisher has to check between Sample size of either 600 or 300 newspapers ,whether it contain a comic section or not.
So, Just Taking a newspaper from a sample size of 600 or 1500 newspapers or 500 or 1000 newspaper and then checking whether it contains Comic section or not will be best way that publisher can adopt.
Time must be kept in mind by the publisher while choosing the sample size.

6) 10 ft is what percent of 135.8 ft?
Answer: 7.364%...............
Answer:
Step-by-step explanation:
small amount = 10
Large amount = 135.8
% = (small amount / large amount ) * 100
% = (10 / 135.8) * 100
% = 0.0736* 100
% = 7.36%

Enlarge the picture below by a scale factor of 3.

Answer:
Im doing the same thing, i dont know the answer, Lol-
Step-by-step explanation:
12. Find all x- and y-intercepts, state the multiplicity of each zero and tell if the graph crosses or
bounces, and state the end behavior Then graph each polynomial by hand,
P(x)=x^2(x-3)^2(x+2)
P(x)=x^4-4x^2
Step-by-step explanation:
12a. To
find x intercepts, set each factor equal to zero
[tex] {x}^{2} = 0[/tex]
[tex]x = 0[/tex]
[tex](x - 3) {}^{2} = 0[/tex]
[tex]x = 3[/tex]
[tex]x + 2 = 0[/tex]
[tex]x = - 2[/tex]
So the x intercepts are( 0,-2,3.)
The multiplicity of 0 and 3 is 2,
The multiplicity of -2 is 1.
The y intercepts are
[tex]0 {}^{2} (0 - 3) {}^{2} (0 + 2) = 0[/tex]
The y intercept is 0.
End Behavior: Since this is a positve 5th root function, as x increases, f(x) increases while as x decreases, f(x) decreases.
The First picture shows the graph of the function. Notice ried the zeroes that have a multiplicity of 2 have a parabolic reflection after thre function reaches their zero.
The zero that have a multiplicity of 1 have just passes through the graph.
12b. We have
[tex] {x}^{4} - 4 {x}^{2} [/tex]
We can easily find y intercept, which is 0.
To find x intercept,
Factor
[tex] {x}^{2} ( {x}^{2} - 4)[/tex]
[tex] {x}^{2} (x + 2)(x - 2) = 0[/tex]
[tex]x = 0[/tex]
[tex]x = 2[/tex]
[tex]x = - 2[/tex]
So the x intercepts are (0,2,-2).
The multiplicity of 0 is 2 while 2 and -2 is 1.
End Behavior: Since this is a positve quartic function, as x increases or decreases , f(x) increases
Look at the second graph,
Answer:
[tex]P(x)=x^2(x-3)^2(x+2)[/tex]
y-intercept is when x = 0:
[tex]\implies P(0)=0^2(0-3)^2(0+2)=0[/tex]
Therefore, y-intercept is at (0, 0)
x-intercept(s) is when P(x) = 0
[tex]\implies x^2(x-3)^2(x+2)=0[/tex]
[tex]\implies x^2=0\implies x=0[/tex]
[tex]\implies (x-3)^2=0\implies x=3[/tex]
[tex]\implies (x+2)=0\implies x=-2[/tex]
Therefore, x-intercepts are:
(0, 0) with multiplicity 2 → bounces(3, 0) with multiplicity 2 → bounces(-2, 0) with multiplicity 1 → crosses x-axisEnd-behavior:
As the lead coefficient is positive and the lead degree is odd,
[tex]P(x) \rightarrow - \infty \textsf{ as }x\rightarrow - \infty[/tex]
[tex]P(x) \rightarrow + \infty \textsf{ as }x\rightarrow +\infty[/tex]
-------------------------------------------------------------------------------
[tex]P(x)=x^4-4x^2[/tex]
y-intercept is when x = 0:
[tex]\implies P(0)=(0)^4-4(0)^2=0[/tex]
Therefore, y-intercept is at (0, 0)
x-intercept(s) is when P(x) = 0
[tex]\implies x^4-4x^2=0[/tex]
[tex]\implies x^2(x^2-4)=0[/tex]
[tex]\implies x^2(x-2)(x+2)=0[/tex]
[tex]\implies x^2=0 \implies x=0[/tex]
[tex]\implies (x-2)=0 \implies x=2[/tex]
[tex]\implies (x+2)=0 \implies x=-2[/tex]
Therefore, x-intercepts are:
(0, 0) with multiplicity 1 → crosses x-axis(2, 0) with multiplicity 1 → crosses x-axis(-2, 0) with multiplicity 1 → crosses x-axisEnd-behavior:
As the lead coefficient is positive and the lead degree is even,
[tex]P(x) \rightarrow + \infty \textsf{ as }x\rightarrow - \infty[/tex]
[tex]P(x) \rightarrow + \infty \textsf{ as }x\rightarrow +\infty[/tex]

How many years it will take to double your money if your
beginning balance is $1,000.00 and earns 10% interest
compounded quarterly?
Answer:
Step-by-step explanation:
The rule says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you want to know how long it will take to double your money at eight percent interest, divide 8 into 72 and get 9 years.

If you subtract 17 from my number and multiply the difference by −2, the result is −8." What is Elise's number?
Answer:
21
Step-by-step explanation:
Result: -8
Subtract: 17
Multiply: -2
The key to finding the number is to reverse the steps given. So instead of subtracting then multiplying, it's supposed to be dividing then adding.
1) -8 / -2
2) 4 + 17
3) 21
How the answer was found with 21:
1) 21 - 17
2) 4 * -2
3) -8

[tex]\[\Boxed\]\ \space\ Hello mathematicians[/tex]
Find the perimeter and the area of a circle when radius is 10 cm.
Note:
✯ No spam
✯ No short answers
Answer:
Step-by-step explanation:
Using 3.14 as pi.
Perimeter of a circle = 2*pi*radius
= 2*3.14*10
= 62.8 cm
Area of a circle = pi*radius*radius
= 3.14*10*10
= 314 cm^2
Solution:
Formulas to remember:
Circumference of circle = 2πr (r = radius)Area of circle = πr² (r = radius)Finding the circumference of the circle:
Circumference of circle = 2πr=> Circumference of circle = 2 x 22/7 x 10=> Circumference of circle = 44/7 x 10=> Circumference of circle = 440/7 ≈ 62.86 cmFinding the area of the circle:
πr² = Area of circle=> 22/7 x 10 x 10 = Area of circle=> 22/7 x 100 = Area of circle=> Area of circle = 2200/7 cm² ≈ 314.29 cm²
