Answers
Answer:
54°
Step-by-step explanation:
In the given question we would like to solve for x .The two marked angles here are vertically opposite angles . And vertically opposite angles are equal .
So here (2x +2)° and (3x - 52)° are equal. Therefore,
[tex]\longrightarrow 2x + 2^o = 3x - 52^o\\ [/tex]
[tex]\longrightarrow 2x - 3x = -52^o -2^o \\ [/tex]
[tex]\longrightarrow -x = -54^o\\[/tex]
[tex]\longrightarrow \underline{\underline{\boldsymbol{ x = 54^o }}} [/tex]
Hence the value of x is 54°
And we are done!
Answer :
54°Explanation :
When two straight lines intersect each other, then the pairs of angles so formed without any common arm are called vertically opposite angles.Here,
[tex] \longrightarrow \sf \qquad \: (3x - 52) {}^{ \circ} = (2x + 2) {}^{ \circ} [/tex]
[tex]\longrightarrow \sf \qquad \: 3x - 2x = 2 {}^{ \circ} + {52}^{ \circ} [/tex]
[tex]\longrightarrow \bf \qquad \: x = {54}^{ \circ}[/tex]

6) 10 ft is what percent of 135.8 ft?
Answers
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%
How many years it will take to double your money if your

compounded quarterly?
Answers
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.

Find the perimeter and the area of a circle when radius is 10 cm.
Note:
✯ No spam
✯ No short answers
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 cm²Blake is saving up to buy a

Find the slope of the line through the pair of points: ( − 3 , 4 ) and ( 0 , 2 ) .
Answers
Answer:
[tex]-\frac{2}{3}.[/tex]
Step-by-step explanation:
1) the required slope can be calculated if to use the ratio:
slope=(y(B)-y(A))/(x(B)-x(A)), where x(A)=-3; y(A)=4; x(B)=0 and y(B)=2;
2) according to the formula above:
s=(2-4)/(0+3)=-2/3.
The slope of the line through the given points is: -2/3.
What is the Slope of a Line?Slope of a line= change in y / change in x = rise/run.
Given the points:
(-3, 4) = (x1, y1)
(0, 2) = (x2, y2)
Slope = (4 - 2)/(-3 - 0)
Slope = 2/-3
Slope of the line = -2/3

Question 6 of 10
f(x) = 5x + 1) – 3
g(x) = 4
Find (f - g)(x).
Answers
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.
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
Answers
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]
