E.C. What is the standard equation of a circle with center (h,k) and radius r in the coordinate plane?
Answer:
(x-h)^2 + (y-k)^2 = r^2
Step-by-step explanation:
Here, we want to write the standard equation of the circle
We have this as;
(x-h)^2 + (y-k)^2 = r^2
The above equation is the standard equation for the circle
Answer:
(x − 4)2 + (y + 6)2 = 25
(x − 4)2 + (y − (-6))2 = 52
When I compare my equation with the standard form, (x − h)2 + (y − k)2 = r2, I get h = 4, k = -6, and r = 5. The center is at (4, -6), and the length of the radius is 5.

Mr. Starnes wondered what proportion of Katy Perry's Twitter followers are
female, so he selected a random sample of 500 of Katy Perry's followers. In the
sample, 308 are female. Construct and interpret a 90% confidence interval for the
true proportion of Katy Perry followers that are female.
Answer and Step-by-step explanation:
To calculate a confidence interval for a proportion:
1) Determine the proportion
[tex]p=\frac{308}{500}[/tex]
p = 0.616
2) A 90% confidence interval has z-score that is 1.645.
3) Calculate margin of error
[tex]ME=\sqrt{\frac{p(1-p)}{n} }[/tex]
where
n is the sample size
So
[tex]ME=\sqrt{\frac{0.616(1-0.616)}{500} }[/tex]
[tex]ME=\sqrt{\frac{0.616(0.384)}{500} }[/tex]
ME = 0.02175
Then the interval is given by
p ± z(ME)
0.62 ± 1.645(0.02175)
0.62 ± 0.035
The interval will be
0.585 < p < 0.655
What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.

Water is pumped out of a 500-gallon tank at a rate of 2.5 gallons per second. The inequality 500−2.5t<100 can be used to determine the time t in seconds, after which there will be less than 100 gallons of water remaining in the tank.
Answer:
[tex]160\ \text{s}[/tex]
Step-by-step explanation:
The inequality that represents the situation is
[tex]500-2.5t<100[/tex] where [tex]t[/tex] is the time in seconds
[tex]\Rightarrow -2.5t<100-500[/tex]
[tex]\Rightarrow -2.5t<-400[/tex]
[tex]\Rightarrow 2.5t>400[/tex]
[tex]\Rightarrow t>\dfrac{400}{2.5}[/tex]
[tex]\Rightarrow t>160\ \text{s}[/tex]
So, the time after which there will be less than 100 gallons of water is [tex]160\ \text{s}[/tex].

Answer:
[tex] y = \frac {1}{2}x +2[/tex]
Step-by-step explanation:
Line is passing through the points (0, 2) & (2, 3)
Slope of line = (3 - 2)/(2 - 0) = 1/2
Equation of line in point slope form is given as:
y - 2 = 1/2(x - 0)
2(y - 2) = x
2y - 4 = x
2y = x + 4
[tex] y = \frac {1}{2}x +\frac {4}{2}[/tex]
[tex] y = \frac {1}{2}x +2[/tex]
is the required equation of blue line.
Answer:
2y-4 =x
Rearranged as:
2y = x + 4
x = 2y - 4
y = x/2 +4

How many terms of the AP -10,-7,-4,-1,.............must be added to get the sum -104?
pls do this fasttttttstttt
Answer:
The value of n is complex
Step-by-step explanation:
The sequence is an arithmetic sequence
Given
First term a = -10
common diff d = -7-(-10) = -4-(-7) = 3
Sn = -104
get the number of terms n using the formula
Sn = n/2[2a+(n-1)d]
-104 = n/2[2(-10)+(n-1)(3)]
-104 = n/2[-20+3n-3]
-208 = n{3n-23}
-208 = 3n²-23n
3n²-23n+208 = 0
Factorize
n = 23±√23²+4(3)(208)/2(3)
n = 23±√529-2496/6
Since the value of n is a complex number, hence the value of n does not exist

Step-by-step explanation: Josie selected a number n. She divided n by 2 and then subtracted ½ from the result. She took
half of that result and then subtracted ½ to get the final result of 10. What is the value of n?
Let’s start by writing Josie’s first step as an expression. Dividing n by 2, then subtracting ½ from
the result would be (n/2) – ½. If we build on this expression with the information in Josie’s
second step, we get ½((n/2) – ½) – ½. Knowing the final result is 10, we can set up the equation
below, and solve for n as follows:
½((n/2) – ½) – ½ = 10
½(n/2) – ¼ - ½ = 10 (using the distributive property)
¼n – ¼ - ½ = 10 (multiplying to eliminate the parentheses)
¼n – ¾ = 10 (combining like terms)
¼n = 10¾ (adding ¾ to both sides of the equation)
n = 43 (dividing both sides of the equation by ¼)

I believe it is A because according to the theorem it states the other pair of opposite sides are parallel.
"Here's the game plan. Assume that ¯BC ¯AD and ¯BC ~= ¯AD. By definition, a parallelogram is a quadrilateral with both pairs of opposite sides parallel. You already know that one pair of opposite sides is parallel. You need to show that the other pair of opposite sides is parallel. In other words, you need to show that ¯AB ¯CD."

Orlando has a bank statement balance of $414.25 and $5.90 service charge. His check register shows $374.16 and he has two outstanding checks of $26.54 and $21.78. Orlando should:
Keep the adjusted checkbook balance.
Write the true balance in his checkbook.
Write the balance from the bank statement in his checkbook.
Answer:
$365.93
$368.26
Step-by-step explanation:
The true balance :
Statement balance - outstanding cheques
Statement balance = 414.25
Outstanding cheques = 26.54 and 21.76
414.25−26.54−21.78 = 365.93

If 13% is lost by selling goods for Rs 1475, what would be the loss or gain if the goods are sold for Rs 1615?
Given:
Loss percent is 13%.
Selling price = 1475
To find:
The loss or gain if the goods are sold for Rs.1615?
Solution:
Let x be the cost price of goods.
Loss percent is 13% and selling price is 1475.
[tex]1475=x-\dfrac{13}{100}x[/tex]
[tex]1475=x-0.13x[/tex]
[tex]1475=0.87x[/tex]
[tex]\dfrac{1475}{0.87}=x[/tex]
[tex]1695.4023=x[/tex]
[tex]x\approx 1695.40[/tex]
The cost price of goods is 1695.40.
We need to find the loss or gain if the goods are sold for Rs.1615.
Cost price is greater than the selling price because 1695.40 > 1615. It means , it is a loss.
[tex]Loss=CP-SP[/tex]
[tex]Loss=1695.40-1615[/tex]
[tex]Loss=80.40[/tex]
The loss percent is
[tex]Loss\%=\dfrac{Loss}{C.P}\times 100[/tex]
[tex]Loss\%=\dfrac{80.40}{1695.40}\times 100[/tex]
[tex]Loss\%\approx 4.74\%[/tex]
Therefore, the loss is 80.40 and the loss percent is about 4.74%.
