Answer 1

Step-by-step explanation:

(x+2)^2 + (y-3)^3 = 4

the #'s in the () are your center coordinates

Do the opposite signs to get (-2, 3)

Then take the square root of 4 to get your radius of 2

Then plot the center and create the circle

pic shown below:

Answer 2

Answer:

See below

Step-by-step explanation:

The center of the circle is (-2, 3) and the radius is [tex]\sqrt{4}[/tex] = 2

I can't graph the circle for you, so go find (-2, 3), go 2 units to the left, right, up and down and put a point at those places. Then sketch the circle. OK?

Find the length of the arc.

Answers

Answer:

18.84 ft

Step-by-step explanation:

¼×2×3.14×12 = 18.84 ft

Step-by-step explanation:

assuming 90° is the central angle measure then the degree measure of the arc would be 90°

though the question asks for length

to do this create a ratio of the degree measurement of the arc divided by the total degree measure of a circle which would be

90/360

next think about circumference, it's the measure of the length around a circle. that would be relevant to what the question is asking so calculate it the formula is C=2*pi*r

calculate and the circumference is 24pi

next multiply the total circumference by the ratio for the section we want in this case 90/360

arc length = 24pi * 90/360 = 6pi

therefore the answer is 6pi or 18.84 substituting 3.14 for pi

Write [tex]cot^{2} x (1+tan^{2} x)[/tex] Then simplify the expression so no quotients appear

Answers

Step-by-step explanation:

From Trig

1 + tan²x = Sec²x

Also

Sec²x = 1/cos²x

Now

Cot²x = 1/tan²x = cos²x/sin²x

Putting all together

Cot²x(1+tan²x)

= Cot²x(sec²x)

= cos²x/sin²x(1/cos²x)

cos²x on the numerator and that one the denominator cancels out

we have

= 1/sin²x

From Trig

1/sin²x = cosec²x

So Our Answer = cosec²x.

Answer:

The Distance = √(y2-y1)² + (x2-x1)²

Notice

The points occur at the same x value (-6)

So We don't have to both about this cos the change will be zero(x2-x1)

Why?

(-6-(-6) = 0.

So we're concerned with the y value

y1= -2

y2= -9

(y2-y1) = -9-(-2) = -9+2 = -7

d= √(-7)²

= √49

=7.

At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?

Answers

Answer:

ΔT = ( -19°C - 11°C) = -30°C

Step-by-step explanation:

When we have a given variable, let's call it X, the change of X in a given interval is written as:

ΔX = (X₂ - X₁)

Where:

X₂ = final value of the variable

X₁ = initial value of the variable.

In this case, we have the temperature, and we know that the initial temperature is 11°C, then:

T₁ = 11°C

While the final temperature is -19°C, then:

T₂ = -19°C

Then the change will be:

ΔT = ( -19°C - 11°C) = -30°C

This is the wanted expression.

Scott strikes out at bat 36% of the time. Find the probability that he strikes out no more than three times on his next eight times at bat.

Answers

Answer:

68.47%

Step-by-step explanation:

The answer is 68.47%

Solution -

We know that,

The binomial formula is -

P(x) = [tex]^{n}C_{x}p^{x}q^{n-x}[/tex]

where

n is the number of trials

x is the strike out number.

p is the probability of success

q is the probability of failure

Here,

n = 8

p = 36% = 0.36

q = 1 - 0.36 = 0.64

Now,

We want to find the probability that he strikes out no more than 3 times (i.e. <= 3.)

So,

We need to check the cases where x = 0, 1, 2 and 3.

Now,

For x = 0,

P(0) = [tex]^{8}C_{0}(0.36)^{0}(0.64)^{8-0}[/tex] = (0.64)⁸

P(1) = [tex]^{8}C_{1}(0.36)^{1}(0.64)^{8-1}[/tex] = 8×0.35×0.64⁷ .

P(2) = [tex]^{8}C_{2}(0.36)^{2}(0.64)^{8-2}[/tex] = 28×0.35² ×0.64⁶ .

P(3) = [tex]^{8}C_{3}(0.36)^{3}(0.64)^{8-3}[/tex] = 56×0.35³ ×0.64⁵ .

So,

Probability that he strikes out no more than three times = P(0) + P(1) + P(2) + P(3) = 68.47%

At track practice, Coach Wilson told the team to split into groups of four for a special relay. The first runner had to run 1 lap around the track (440 yards). The second runner had to run 2 laps around the track. The third runner had to to run 3 laps around the track. The final runner had to run 4 laps around the track (1 mile). How many yards did each relay team team have to run altogether? *

Answers

You can multiply the number of laps each person ran by the yards in each lap and then add them together:

440 + 2(440) + 3(440) + 4(440)
= 440 + 880 + 1,320 + 1,760
= 4,440 yards

Or you can add the laps first, then multiply by the yards in each lap
(1 + 2 + 3 + 4)(440)
= 10 x 440
= 4,400 yards

Read this excerpt from "Mad Cow, Furious Farmer."The disease was first detected in England in 1986, though some scientists think the very first cases started at least ten years before. Cows usually eat only grass and other plants, but farmers had been feeding them a meat and bone mixture that made the cows plumper. But somehow, at least one batch of the mixture had become contaminated with what was then an unknown killer: a prion.By 1993, British farmers were reporting up to one thousand new cases of BSE a week. Governments all around the world reacted by increasing testing for the disease and not allowing any cows to be eaten if they were at risk of having the disease. As sheep can also get a prion disease called scrapie, they were tested as well. Farmers were angry that they were losing their livestock, and nobody knew how to protect cows and people from the disease.Consumers were also in a panic when they learned about BSE, and for a very good reason: prions are infectious. If you eat a prion from a "mad cow or sheep, you are at risk for developing a human version of BSE. The public felt betrayed that their governments had underreacted to the problem or covered it up.Eventually, in 1997, governments began to ban farmers from feeding their livestock high-risk meat and bone mixtures. With that ban, the epidemic quickly peaked, and by 2010 had largely disappeared. Over the years, half a million cows and two hundred people had been killed by prions.In the end, the BSE epidemic was a watershed moment, or turning point, in public health. Citizens were enraged at their governments for having kept prions a secret. Governments, who had lost the public trust, struggled to find the best way to communicate health risks without creating unnecessary panic.How does the author's use of chronology help support the idea that the BSE epidemic was a watershed moment, or turning point, in government use of law to support public health?o The author lays out a timeline to show how scientific discoveries made governments less likely to make laws for public health.o The author makes it clear that prions were always known to be dangerous and that scientists discovered them to be the cause of mad cow disease.o The author discusses how the mad cow disease epidemic ended only about twenty-five years after it first became a problem.o The author shows how frustrated people were that nothing was done about a disease until over ten years after it was discovered.
