Answer:
(-9,6)
Step-by-step explanation:
The center of a circle represented by the equation is (-9, 6)
Equation of a circle
The standard equation of a circle is expressed as:
(x- a)^2+(y−b)^2= r^2
where:
r is the radius of the circle
(a, b) is the center
Given the equation of a circle expressed as (x+9)^2+(y−6)^2=10^2, on comparing;
a = -9
b = 6
Hence the center of a circle represented by the equation is (-9, 6)

Simplify the expression below as much as possible. (7-i) + (5+3i) - (-3 +2i)
The simplified expression is 15 + 2i.
To simplify the expression (7 - i) + (5 + 3i) - (-3 + 2i), we can combine like terms. First, let's remove the parentheses: 7 - i + 5 + 3i - (-3 + 2i)Next, distribute the negative sign to the terms inside the parentheses: 7 - i + 5 + 3i + 3 - 2iNow, let's combine the real parts and the imaginary parts separately: (7 + 5 + 3) + (-i + 3i - 2i)Simplifying further: 15 + 2iTherefore, the simplified expression is 15 + 2i.In conclusion, the simplified expression (7 - i) + (5 + 3i) - (-3 + 2i) simplifies to 15 + 2i.

Convert the equation below to slope-intercept form
6x+ 8y = -32
Answer:
y = -3/4x - 4
Step-by-step explanation:
Convert the equation to slope intercept form by isolating y
6x + 8y = -32
Subtract 6x from both sides
8y = -6x - 32
Divide each side by 8
y = -6/8x - 4
Simplify -6/8 to -3/4
y = -3/4x - 4
So, the equation in slope intercept form is y = -3/4x - 4
A bank account earns interest at a rate of 3.5% per year (in other words it increases in value by that percent) and starts with a balance of $350. Which of the following equations would give the account’s worth, W, as a function of the number of years, y, it has been gaining interest?
Answer:
Annually cumulating interest can be determined by the following formula:
W=P(1+r)^y
r represents the interest rate as a decimal, and P represents the starting amount of money.

Find the distance between the two points rounding to the nearest tenth
(if necessary).
(-7, -6) and (-3,2)
Submit Answer
Answer:
Answer:
8.9
Step-by-step explanation:
To solve this problem you just use the distance equation which is √((x1-x2)^2+(y1-y2)^2). It does not matter which point you use where but if you use -7 as your x1, you have to use -6 as your x1.
The process should look like this
√(-7-(-3))^2+(-6-2)^2)
√((-4)^2+(-8)^2)
√(16+64)
√(80)
=8.944 or 8.9 rounded to the nearest tenth
Which of the following values are in the range of the function graphed below? Check all that apply.
Given:
The graph of a function.
To find:
The range of the function.
Solution:
Domain is the set of input values for which the function is defined.
Range is the set of output values or y-values.
From the given graph it is clear that the function is defined between -2 and 1.
The graph of the function is a horizontal line and it gives the value 1 for each input between -2 and 1.
It means the range of the graphed function is 1.
Therefore, the correct option is C.

An athlete ran 10 times around the circular track shown below. Approximately how many meters did the athlete run?
Answer:
Step-by-step explanation:
Since the picture isn't given. I have no idea what the radius or diameter is and as such, have no definite answer for you.
However, from the question, if he's to run round the circular track once, then he must have run a total of
2πr meters, with r being the radius.
Now, the question says that he ran round the track 10 times, this means that whatever value we get there, for 1 trial, we multiply it by 10, to get the value for 10 trials. Essentially,
10 * 2πr
The value gotten is the needed answer. All you have to do is substitute r for the value you have in your diagram. We already know that π is 3.142

.3, 1/3, 2/5, 1/2, .6
Answer:
0.3, 1/3, 2/5, 1/2, 0.6
Step-by-step explanation:
Divide 1 by 3 and you get 0.333. Divide 1 by 2 and you get 0.5. Then divide 2 by 5 and you get 0.4. From there it's easier to compare. You could also make the decimals into fractions, but comparing those would take more steps by trying to find similar denominators.
