Name four angles between 0 and 360 degrees with a reference angle of 20 degrees Show work
Answer with explanation:
Reference Angle =20°
Angle Lies in First Quadrant.
⇒≡Reference Angle of 20°, which should lie between 0° and 360° can be evaluated by using the formula=360°n+20°, for n=0,1,2,3,4,....
So,First Reference angle of 20°=20°
Second reference angle of 20°=360°× 1+20°=380°
Third Reference angle of 20°=360°× 2+20°
=720°+20°
=740°
Fourth Reference angle of 20°=360°×3+20°
=1080°+20°
=1100°
Which table shows the same rate of change of y with respect to x as y =4-5/8x? How would I even figure this out?
Table A
Table B
Table C
Table D
Answer:
Table B
Step-by-step explanation:
from the given equation
[tex]y=4-\dfrac{5}{8}x[/tex]
now to figure out the table which is correct we will insert values of x one by one in the given equation and will find the value of y.
Table A [tex]y=4-\dfrac{5}{8}(-3)[/tex]
[tex]y=4+\dfrac{15}{8}[/tex]
Table B [tex]y=4-\dfrac{5}{8}(-4)[/tex]
[tex]y=4+2.5[/tex] = 6.5
Table C [tex]y=4-\dfrac{5}{8}(-4)[/tex]
[tex]y=4+2.5[/tex] = 6.5
Table D [tex]y=4-\dfrac{5}{8}(-3)[/tex]
[tex]y=4+\dfrac{15}{8}[/tex]
hence the correct answer is Table B

Step-by-step explanation:
in the diagram below eg=100, ef=4x-20, and fg=2x+30
The lengths of segments x=15, EF=40, FG=60.
To solve for x, we can use the fact that the total length of segment EG is equal to the sum of the lengths of segments EF and FG.
EG = EF + FG
Substituting the given values, we get:
100 = 4x - 20 + 2x + 30
Combining like terms, we get:
100 = 6x + 10
Subtracting 10 from both sides, we get:
90 = 6x
Dividing both sides by 6, we get:
15 = x
Therefore, the value of x is 15.
We can now solve for the lengths of segments EF and FG.
EF = 4x - 20
Substituting the value of x, we get:
EF = 4(15) - 20
EF = 60 - 20
EF = 40
FG = 2x + 30
Substituting the value of x, we get:
FG = 2(15) + 30
FG = 30 + 30
FG = 60
Therefore, the lengths of segments EF and FG are 40 and 60, respectively.
Answer:
x = 15
EF = 40
FG = 60

Find the solution(s) to x2 – 14x + 49 = 0
Answer:
x=7
Step-by-step explanation:
[tex]x^2 - 14x + 49 = 0[/tex]
Factor the left hand side of the equation
product is 49 and sum is -14
-7 times -7 is 49
-7 plus -7 is -14
so two factors are -7 and -7
[tex]x^2 - 14x + 49 = 0[/tex]
[tex](x-7)(x-7)= 0[/tex]
Now we apply zero factor property
SEt each factor =0 and solve for x
x-7 =0 , x=7
The correct solution for the equation [tex]x^{2}- 14x+49 = 0[/tex] is [tex]x = 7[/tex].
Given equation,
[tex]x^{2}- 14x+49 = 0[/tex]
The equation is a quadratic equation. A polynomial equation of second degree is known as quadratic equation.
The standard form of a quadratic equation is:
[tex]ax^{2} + bx + c = 0[/tex]
Find the solution of given equation for x, Use the standard formula:
x = (-b ± √(b² - 4ac)) / (2a)
From the question,
a = 1, b =-4 , c = 49.
Put the value of a, b ,c in the formula to find x.
x = (-(-14) ± √((-14)² - 4(1)(49))) / 2(1)
= (14 ± √(196 - 196)) / 2
= (14 ± √(0)) / 2
= [tex]\dfrac{14}{2}[/tex]
= 7
The value of the discriminant [tex]\sqrt{b^{2} - 4ac }[/tex] is 0. this indicates that their will be only one value of x.
The equation [tex]x^{2}- 14x+49 = 0[/tex] has a single solution which is x =7.

A 5 in by 7in photograph is surrounded by a frame of uniform width the area of the frame equals the area of the photograph find the width of the frame
Let x be the
width of the frame.
Area of the picture is 5*7 = 35 sq in
Area of the frame given as the same, frame = 35 sq in also
Therefore the total area (picture & frame) will be 70 sq in
A simple equation would be made and it will look like this: (7+2x) * (5+2x) =
70
Using the FOIL
method
35 + 14x + 10x + 4x^2 = 70
4x^2 + 24x + 35 - 70 = 0; subtract 70 from both sides:
4x^2 + 24x - 35 = 0
unluckily this will not factor easily, so we should use the quadratic equation:
where: a = 4; b = 24; c = -35
x = -b sqrt b^2 – 4*a*c divided by 2 * a
x
= -24 ±
sqrt 24^2 -4*4*(-35) divided by 2*4
x = -24 ±sqrt 576 -
-(560) divided by 8
x = -24 ± sqrt 576 + 560 divided by 8
x = -24 ± sqrt1136

x = -24 + 33.7046 divided by 8

How do you solve for m using the equation 5.01cm^3=m/1.2cm^3
To solve for 'm' in the equation 5.01cm^3 = m/1.2cm^3, multiply both sides of the equation by 1.2cm^3. This yields the solution m approx = 6.012cm^6.
Explanation:To solve the equation 5.01cm^3 = m/1.2cm^3 for m, you should first isolate m by multiplying both sides of the equation by 1.2cm^3. So, it becomes 5.01cm^3 * 1.2cm^3 = m. By conducting this multiplication, you get approximately 6.012 cm^6 = m. So, the solution to the equation is m approx = 6.012cm^6
To solve for m in the equation 5.01 cm3 = m / 1.2 cm3, we need to isolate the variable m. To do this, we can multiply both sides of the equation by 1.2 cm3. This cancels out the units of cm3 on the right side, leaving us with 5.01 cm3 * 1.2 cm3 = m.
Next, we can perform the multiplication to find the value of m. 5.01 cm3 * 1.2 cm3 = 6.012 cm3. Therefore, m = 6.012 cm3.
So, the solution to the equation is m = 6.012 cm3.

Given the quadratic function 3x^(2) =8x-5 what are the values of x?
Answer:
The values of x are [tex]\frac{5}{3}[/tex] and 1.
Step-by-step explanation:
Given quadratic function[tex]3x^2=8x-5[/tex]
We have to solve for x.
Consider the given quadratic function [tex]3x^2=8x-5[/tex]
This can be written as [tex]3x^2-8x+5=0[/tex]
We can solve the above quadratic equation using middle term split method,
-8x can be written as -3x - 5x
Thus, the equation becomes,
[tex]3x^2-8x+5=0[/tex]
[tex]\Rightarrow 3x^2-3x-5x+5=0[/tex]
Taking 3x common from first two term and -5 common from last two terms, we get,
[tex]\Rightarrow 3x(x-1)-5(x-1)=0[/tex]
[tex]\Rightarrow (3x-5)(x-1)=0[/tex]
Now using zero product property [tex]a.b=0 \Rightarrow a=0\ or\ b=0[/tex] , we have,
[tex]\Rightarrow (3x-5)=0[/tex] or [tex]\Rightarrow (x-1)=0[/tex]
[tex]\Rightarrow x=\frac{5}{3}[/tex] or [tex]\Rightarrow x=1[/tex]
Thus, The values of x are [tex]\frac{5}{3}[/tex] and 1.

Fred the clown can create 17 animal balloons every 15 minutes.how many animal balloons he could create in 30 minutes and in 60 minutes.
Answer:
34 balloons in 30 minutes.
68 balloons in 60 minutes.
Step-by-step explanation:
We have been given that Fred the clown can create 17 animal balloons every 15 minutes. We are asked to find the number of balloons created by Fred in 30 minutes and 60 minutes.
To find number of balloons created by Fred in 30 minutes, we will multiply 17 by 2 as 30 is 2 times 15.
[tex]\text{Balloons created in 30 minutes}=2\times 17[/tex]
[tex]\text{Balloons created in 30 minutes}=34[/tex]
Therefore, Fred can create 34 balloons in 30 minutes.
To find number of balloons created by Fred in 60 minutes, we will multiply 17 by 4 as 60 is 4 times 15. This means Fred will create 4 times more balloons in 60 minutes than 15 minutes.
[tex]\text{Balloons created in 60 minutes}=4\times 17[/tex]
[tex]\text{Balloons created in 60 minutes}=68[/tex]
Therefore, Fred can create 68 balloons in 60 minutes.
