Answer:
A
Step-by-step explanation:
From looking at the graph, you can see that the center point of the circle is at (5, -3), so to figure out the diameter, you need to find the distance of that line ( y = - 3 ) that the circle is on. The diameter is about 6 point something which in the square root form can be represented by √36.
After knowing the diameter is about 6, choice C can be eliminated.
2√10 = √40
4√10 = √160
2√34 = √136
After expanding the square root, we can know that the closest option is A.
Check the picture below.
so we know the circle has that center and passes through (2 , -2), let's find its radius, keeping in mind that diameter = 2 * radius.
[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~5 - 2~~)^2 + (~~-3 - (-2)~~)^2} \implies r=\sqrt{(5 -2)^2 + (-3 +2)^2} \\\\\\ r=\sqrt{( 3 )^2 + ( -1 )^2} \implies r=\sqrt{ 9 + 1 } \implies r=\sqrt{ 10 }~\hfill \underset{diameter}{\stackrel{(2)(r)}{2\sqrt{10}}}[/tex]

Question 4
Ralph deposited $10,500 in an CD account that pays 1.75% simple interest for 30 months.
How much interest will this CD have earned after 30 months?
$
What is the new balance at maturity (30 months)?
2 pts
The CD will earn $459.375 interest in 30 months and the balance at maturity will be $10,959.375.
Here, we are given that Ralph deposited $10,500 in an CD account that pays 1.75% simple interest for 30 months.
Simple interest can be calculated using the following formula-
Simple interest = Principle(P) × Time(t) × Rate(r)/ 100
Here,
P = 10,500
t = 30/12
r = 1.75
Thus,
Simple interest = 10,500 × 30/12 × 1.75/ 100
= 10,500 × 5/2 × 175/ 10000
= 10,500 × 5/2 × 7/ 400
= 26,250 × 7/ 400
= $459.375
Thus, the CD will earn $459.375 interest in 30 months.
Balance on maturity will be-
$10,500+ $459.375 = 10,959.375
Thus, the balance at maturity will be $10,959.375.

help would be so appreciated!
Answer:
x =23
Step-by-step explanation:
ok first, the full degree of a straight line is 180°
subtract 38° out of 180°
180-38= 142
so 6x+4= 142°
subtract 4 from both sides of the equation
6x +4 -4= 142-4
6x=138
divide 6 from 6x and 138
x=23

Answer:
Do you have any numbers?
Can someone explain these two?
Answer:
I believe you cancel out values if there are the same ones for the numerator and dominator.
For example:
[tex]\frac{x^4+x^2+x-3}{x^4+x^3-3}[/tex]
Since both the numerator and dominator have [tex]x^4[/tex] and -3, you are able to cancel them out.
This would leave you with [tex]\frac{x^2+x}{x^3}[/tex]
Notes: the exponents have to be the same number in order to cancel out the values.
Answer:
11. C) x +1
12. B) x -1
Step-by-step explanation:
You want the simplified form of a couple given rational expressions.
Each of the polynomials can be factored by pairs. Common factors can be cancelled.
11.Factoring numerator and denominator pairwise, we have ...
[tex]\dfrac{x^3+2x^2-x-2}{x^2+2x-x-2}=\dfrac{x^2(x+2)-1(x+2)}{x(x+2)-1(x+2)}=\dfrac{(x^2-1)(x+2)}{(x-1)(x+2)}\\\\=\dfrac{x^2-1}{x-1}=\dfrac{(x+1)(x-1)}{(x-1)}=\boxed{x+1}[/tex]
12.Factoring the numerator pairwise,, we have ...
[tex]\dfrac{x^5-x^4+x^3-x^2+x-1}{x^4+x^2+1}=\dfrac{x^4(x-1)+x^2(x-1)+1(x-1)}{x^4+x^2+1}\\\\=\dfrac{(x^4+x^2+1)(x-1)}{(x^4+x^2+1)}=\boxed{x-1}[/tex]

solve linear equation
[tex] \Large{\boxed{\sf x = 4}} [/tex]
[tex] \\ [/tex]
Explanation:Solving this equation means finding the value of 'x' that makes the equality true.
[tex] \\ [/tex]
Given equation:
[tex] \sf -12 + 5x - x = x - 7 + 7 [/tex]
[tex] \\ [/tex]
Combine like terms:
[tex] \sf -12 + (5x - x) = x + (-7 + 7) \\ \\ \sf -12 + 4x = x [/tex]
[tex] \\ [/tex]
Now, we move the variables to the right side of the equation by subtracting 4x from both sides:
[tex] \sf -12 + 4x - 4x = x - 4x \\ \\ \sf -12 = -3x [/tex]
[tex] \\ [/tex]
Finally, divide both sides of the equation by the coefficient of the variable, -3:

y=4x+3 table of ordered pairs
Answer:
X:1 2 3 4 5 Y:7 11 15 19 23.
Step-by-step explanation:
We just need to put in the values of x into the equation: y = 4x + 3.
x = 1:
y = 4(1) + 3
= 4 + 3
y = 7
x = 2:
y = 4(2) + 3
= 8 + 3
y = 11
x = 3:
y = 4(3) + 3
= 12 + 3
y = 15
x = 4:
y = 4(4) + 3
= 16 + 3
y = 19
x = 5:
y = 4(5) + 3
= 20 + 3
y = 23
For what values of the variable x, is the fraction x-3/5 equal to: 1

Answer:
property of equality that justifies the missing step is Division property of equality
Step-by-step explanation:
We need to Identify the property of equality that justifies the missing step

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

Marine life depends on the microscopic plant life that exists in the photic zone, a zone that goes to a depth where only 1% of surface light remains. In some waters with a great deal of sediment, the photic zone may go down only 15 to 20 feet. In some murky harbors, the intensity of light d feet below the surface is given approximately by I= I0e^-0.23d

Answer:
Step-by-step explanation:

x + 2x -75 = 90
3x = 90+75
3x = 165
x = 55
Measure of A = 55
Measure of B = 2(55) - 75 = 110 - 75 = 35
28.
2x+10-x+55 = 90
x = 90-65
x = 25
measure of A = 2(25) +10 = 60
measure of B = -25+55 = 30
31.
2x+3+3x - 223 = 180
5x -220 = 180
5x = 400
x = 80
measure of A = 163
measure of B = 17
32.
-4x+40+x+50 = 180
-3x +90 = 180
-3x = 90
x= -30
measure of A = -4(-30) +40 = 160
measure of B = -30+50 = 20
