Find the center and radius of
x2 + y2 + 2x – 10y + 10 = 0
Answers
x^2 + y^2 + 2x – 10y + 10 = 0
x^2 + 2x + y^2 - 10y = 0
We must complete the square in x and y.
(x^2 + 2x + 1) + (y^2 -10y + 25) = 4 + 25
(x + 1)^2 + (y - 5)^2 = 29
The radius r is found solving r^2 = 29 for y.
(x + 1)^2 + (y - 5)^2 = sqrt{29}
See picture for the center and radius.

A golfer wants to determine if the type of driver she uses each year can be used to predict the amount of improvement in her game. Which variable would be the explanatory variable?a. The type of driverb. The number of holes she playsc. The rating of the golferd. The improvement in her game
Answers
Answer:
The type of driver
Step-by-step explanation:
The term known as '' response variable'' is use in describing a variable that changes when you alter an examination or a test. Just like its name implies, it is the ''response'' that one gets when the other variable that is the Explanatory Variable are being altered.
In this question, the golfer will have to be changing the type of drivers that she is using in order to be able to know whether these changes in drivers will increase her game performance. Hence, the Explanatory Variable is the type of driver in which the golfer changes which is being use to define the performance of the golfer.

Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = −1
Answers
Answer:
Step-by-step explanation:
If you plot the focus and the directrix you see that the focus is above the directrix. Since a parabola always wraps itself around the focus, this parabola opens upwards and has the standard form equation:
[tex](x-h)^2=4p(y-k)[/tex] where h and k are the coordinates of the vertex and p is the number of units between the vertex and the focus, or the vertex and the directrix. This number of units will be the same for both since the vertex is smack dab inbetween the focus and the directrix. The focus is also on the axis of symmetry, which means that it shares the x coordinate with the vertex (which is actually the h coordinate) of -5. Halfway between the y value of 5 and the y value of -1 is 2. So the vertex is located at (-5, 2). The number of units between the vertex and the focus is 3, so the equation is:
[tex](x+5)^2=4(3)(y-2)[/tex] and simplify a bit to
[tex](x+5)^2=12(y-2)[/tex]
I'm not sure how far down you need to simplify that. Taking it a few steps further gives you:
[tex]\frac{1}{12}(x+5)^2=y-2[/tex] and then to
[tex]\frac{1}{12}(x+5)^2+2=y[/tex]
It all depends upon the form you're being asked for.

Step-by-step explanation:V = 4/3(π)[tex]R^{3}[/tex]
You can easily find the radius by dividing
[tex]\frac{33}{2} = 16.5[/tex]
We substitute R = 16.5 into the formula for V:
V = 4/3π[tex]R^{3}[/tex]
4/3(3.14)*[tex](16.5)^{3}[/tex]
= 18807.03 cm

As the PR director you have a $65,000 annual budget. It's the end of June, and you have steadily spent 1/12 of the budget each month so far. But you just had to spend an extra $6,000 in June on crisis management. For the last six months of the year, what will be your adjusted monthly PR budget?
Answers
Answer:
$4,417
Step-by-step explanation:
$4,417
The adjusted monthly PR budget for last six months of the year is $4417.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Annual budget of PR director = $65,000
Monthly spent = [tex]\frac{65000}{12}[/tex]
⇒ [tex]5416.66[/tex] ≈ [tex]\$5417[/tex]
Last month had to spend an extra amount = $6,000
Thus adjusted monthly PR budget for last 6 months is
⇒ [tex]5417-\frac{6000}{6}[/tex]
⇒ [tex]5417-1000[/tex]
⇒ [tex]\$4417[/tex]
Hence we can conclude that the adjusted monthly PR budget for last six months of the year is $4417.

A store is having a sale on jelly beans and almonds. For 5 pounds of jelly beans and 3 pounds of almonds, the total cost is $13. For 2 pounds of jelly beans and 6 pounds of almonds, the total cost is $16. Find the cost for each pound of jelly beans and each pound of almonds.
Answers
Answer:
The cost for each pound of jelly beans and each pound of almonds is $1.25 and $2.25 respectively.
Step-by-step explanation:
Let the cost for each pound of jelly beans and each pound of almonds be x and y respectively.
ATQ,
For 5 pounds of jelly beans and 3 pounds of almonds, the total cost is $13.
5x+3y = 13 ...(1)
For 2 pounds of jelly beans and 6 pounds of almonds, the total cost is $16.
2x+6y = 16
x + 3y = 8 ....(2)
Subtract equation (2) from (1)
5x+3y-(x + 3y)= 13-8
4x = 5
x = 5/4
x = $1.25
Put the value of x in equation (2) as follows :
1.25 + 3y = 8
3y = 8-1.25
y =$2.25
Hence, the cost for each pound of jelly beans and each pound of almonds is $1.25 and $2.25 respectively.

D.Olivia babysat for a total of 8.5 hours.
Answers
Answer
a
Step-by-step explanation:
Answer:
Olivia babysat for a total of 15 hours.
Step-by-step explanation:
8.50(h) + 12 = 139.50
In order to get a direct result of the hours she
worked, we have to subtract 12 on both sides:
8.50(h) + 12 - 12 = 139.50 - 12
In order to fine the value of time she spent, we have to divide the amount of money she got on both sides:
8.50(h) = 127.5
8.50 = 8.50
h = 15
Therefore, Olivia babysat for a total of 15 hours.

101.6 feet
Step-by-step explanation:
First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2
The perimeter of the four other windows: (3.6+4.8)*2=16.8
The total number of feet needed for the first two windows:
17.2*2 = 34.4 feet
The total number of feet needed for the four windows:
16.8*4 = 67.2 feet
The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.
Santa gave kittens to 13 boys and girls. What is the ratio of kitten ears to kitten tails?
Answers
Answer:
[tex]Ratio = 2 : 1[/tex]
Step-by-step explanation:
Given
[tex]Population = 13[/tex] --- Boys & Girls
Required
Determine the ratio of the kitten ears to the tails
A kitten has 1 tail and 2 ears.
Assume each individual got 1 kitten each
This implies that,
[tex]Number\ of\ tails= 1 * 13[/tex]
[tex]Number\ of\ tails= 13[/tex]
[tex]Number\ of\ ears= 2* 13[/tex]
[tex]Number\ of\ ears= 26[/tex]
The ratio of ears to tail is then calculated as follows:
Ratio = Number of ears : Number of tails
This gives
[tex]Ratio = 26 : 13[/tex]
Divide by 13
[tex]Ratio = 26/13 : 13/13[/tex]
[tex]Ratio = 2 : 1[/tex]

Find the probability that a single reading is between 8 and 10
Answers
Answer:
The value is [tex]P(8 < X < 10 ) = 0.8186[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 10 .0[/tex]
The standard deviation is [tex]\sigma = 1[/tex]
Generally the probability that a single reading is between 8 and 10 is mathematically represented as
[tex]P(8 < X < 10 ) = P( \frac{8 - 10 }{ 1} < \frac{X - \mu }{ \sigma } < \frac{10 - 10 }{1} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(8 < X < 10 ) = P( -2 < Z< 1 )[/tex]
=> [tex]P(8 < X < 10 ) = P( Z< 1 ) - P( Z < -2 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1 and -2 is
[tex]P( Z< 1 ) = 0.84134[/tex]
and
[tex]P( Z < -2 ) = 0.02275[/tex]
=> [tex]P(8 < X < 10 ) = 0.84134 - 0.02275[/tex]
=> [tex]P(8 < X < 10 ) = 0.8186[/tex]
A researcher records the repair cost for 27 randomly selected refrigerators. A sample mean of $60.52 and standard deviation of $23.29 are subsequently computed. Determine the 90% confidence interval for the mean repair cost for the refrigerators. Assume the population is approximately normal.
Answers
Answer:
53.15≤x≤67.89
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar±(z×s/√n)
xbar is the sample mean
z is the z score at 90% CI
s is the standard deviation
n is the sample size
Given
xbar = $60.52
s = $23.29
n = 27
z = 1.645
Substitute into the formula
CI = xbar±(z×s/√n)
CI = 60.52±(1.645×23.29/√27)
CI = 60.52±(1.645×23.29/5.196)
CI = 60.52±(1.645×4.482)
CI = 60.52±7.373
CI = [60.52-7.373, 60.52+7.373]
CI = [53.15, 67.89]
Hence the 90% confidence interval for the mean repair cost for the refrigerators is 53.15≤x≤67.89
