A circle with the center C (4, -2) contains the point D (8,1). What is the equation of the line perpendicular to the radius of the circle passing through point C?
Answers
Answer:
y = -4x/3 + 10/3
Step-by-step explanation:
We find the slope of CD and get (-2 - 1)/(4 - 8) = -3/-4 = 3/4
The slope of a perpendicular line is the opposite reciprocal of the slope of the line it's perpendicular to, so we get a slope of -4/3.
We can use point-slope form and get (using point C):
y - (-2) = (-4/3)(x - 4) -->
y + 2 = -4x/3 + 16/3 -->
y = -4x/3 + 10/3

The mass of the apples harvested from a particular orchard follows a nearly normal distribution with a mean of 94 grams and a standard deviation of 27 grams. What size sample is needed to get a standard error of 3
Answers
The sample size needed to get a standard error of 3 is 81
How to determine the sample size?The given parameters are:
Mean = 94Standard deviation = 27Standard error = 3The standard error is calculated using:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
So, we have:
[tex]3= \frac{27}{\sqrt n}[/tex]
Divide both sides by 3
[tex]1= \frac{9}{\sqrt n}[/tex]
Square both sides
1 = 81/n
Multiply both sides by n
n = 81
Hence, the sample size needed to get a standard error of 3 is 81

During a clothing store's Bargain Days, the regular price for T-shirts is discounted by $6. There is a state sales tax of 5%, and the $6 discount is applied before the
sales tax is calculated. A). Write an expression that shows the regular price r of a T-shirt minus the $6 discount. B). Write a rule for the function p(r) that expresses the
final price p of a T-shirt with the discount applied and sales tax added. C). How much would you pay during Bargain Days for a shirt regularly priced at $20.00?
Answers
Answer:
A) The expression that shows the regular price minus the discount is r - 6
B) The function is p(r) = 1.05r - 6.3
C) You would pay $14.7 during Bargain Days
Step-by-step explanation:
∵ The regular price is r
∵ The discount on it is 6%
∴ The price after the discount = r - 6
A) The expression that shows the regular price minus the discount is
r - 6
∵ The state sales tax is 5% applied after the discount
∴ The sales tax = 5%(r - 6)
→ Change 5% to decimal y dividing it by 100
∵ 5% = [tex]\frac{5}{100}[/tex] = 0.05
∴ The sales tax = 0.05(r - 6) = 0.05(r) - 0.05(6)
∴ The sales tax = 0.05r - 0.3
∵ p is the price of the T-shirt with discount and sales tax
→ Add the sales tax to the regular price minus the discount
∴ p(r) = r - 6 + 0.05r - 0.3
→ Add the like terms
∴ p(r) = (r + 0.05r) + (-6 - 0.3)
∴ p(r) = 1.05r + (-6.3)
∴ p(r) = 1.05r - 6.3
B) The function is p(r) = 1.05r - 6.3
∵ The regular price of a shirt is $20
→ Substitute r by 20 in the function above to find how much you would
pay during the Bargain Days
∴ p(20) = 1.05(20) - 6.3
∴ p(20) = 21 - 6.3
∴ p(20) = $14.7
C) You would pay $14.7 during Bargain Days

The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T minus A, where T is the temperature of the coffee, A is the room temperature, and k is a positive constant. If the coffee cools from 100°C to 90°C in 1 minute at a room temperature of 25°C, find the temperature, to the nearest degree Celsius of the coffee after 4 minutes.

Answers
Answer:
(b) 67
Step-by-step explanation:
A solution to the differential equation describing the temperature according to Newton's Law of Cooling could be written as ...
T = (final temp) + (initial difference)×(decay factor)^t
where the decay factor is the fraction of change during 1 unit of time period t.
__
Here, the initial difference of 100-25 = 75 degrees decays to 90-25 = 65 degrees in 1 minute. So, the units of t are minutes, the decay factor is 65/75, the initial difference is 75 degrees, and the final temperature is 25 degrees. That lets us write the equation as ...
T = 25 +75(65/75)^t
Then for t=4, the temperature is ...
T = 25 +75(13/15)^4 ≈ 67.3 . . . . degrees
After 4 minutes the temperature of the coffee is about 67 degrees.

An exercise bike is on sale for $320, having been marked down 20% off the regular price. Find the regular price.
Answers
Answer:
[tex]\$ 400[/tex].
Step-by-step explanation:
In this question, [tex]S[/tex] (sales price) and [tex]r[/tex] (discount rate) are both given. The unknown is the regular price, [tex]R[/tex].
Rearrange the discount equation to solve for [tex]R[/tex] in terms of [tex]S[/tex] and [tex]r[/tex].
[tex]S = R - r\, R[/tex].
[tex]S = (1 - r)\, R[/tex].
Divide both sides by [tex](1 - r)[/tex]:
[tex]\displaystyle \frac{S}{1 - r} = \frac{(1 - r)\, R}{1 - r}[/tex].
[tex]\begin{aligned}R &= \frac{S}{1 - r}\end{aligned}[/tex].
It is given that [tex]S = 320[/tex]. A mark-down of [tex]20\%[/tex] is equivalent to a discount rate of [tex]r = 20 / 100 = 0.20[/tex]. Substitute in [tex]S[/tex] and [tex]r[/tex] to find the value of [tex]R[/tex]:
[tex]\begin{aligned}R &= \frac{S}{1 - r} \\ &= \frac{320}{1 - 0.2} \\ &= \frac{320}{0.8} \\ &= 400\end{aligned}[/tex].
Thus, the regular price would be [tex]\$ 400[/tex].

What is Measurement units?
A measurement unit is a standard quality used to express a physical quantity.
Given that;
Thickness of a sheet of notebook paper = 0.004 inch
Now,
1 inch = 2.54 cm
Hence, Thickness of a sheet of notebook paper = 0.004 inch
= 0.004 × 2.54 cm
= 0.01016 cm
= 0.01 cm
So, Thickness of a 500 sheet stack of notebook paper = 500 × 0.01
= 5 cm
Thus, Thickness of a 500-sheet stack of notebook paper is 5 cm.
