What is the equation of a circle with a center at (−3, 2) and radius 16?

Answers

Answer:

(x+3)^2 + (y+2)^2 = 16

Step-by-step explanation:

hi!

so the equation of a circle with the center (h,k) and a radius r is:

(x-h)^2+(y+k)^2 = r^2

- h is the x value

- k is the y value

- r is the radius

so using your information you can plug in the given values into the "blanket" formula

which would result in:

(x--3)^2 + (y+2)^2 = 16^2 --> since there is a double negative, you can change that to a positive :)

this means that your equation is:

[tex](x+3)^{2} + (y+2)^{2} = 16^2[/tex]

and you can even simplify 16^2 = 256

end formula!

[tex](x+3)^{2} +(y+2)^{2} = 256[/tex]

Ashley and Emma are reading the same article. Ashley is on page 1 of the article, but she can read 1 page per minute. Emma is already on page 5, but reads a page every 3 minutes.

What page is Ashley on after 5 minutes.

What equation can be used to represent the amount Emma has read?

How many minutes does it take before Ashley and Emma have read the same amount

Answers

Answer:

Part A)

Ashley will be on the sixth page.

Part B)

[tex]\displaystyle p=\frac{1}{3}m+5[/tex]

Part C)

Six minutes.

Step-by-step explanation:

Ashley is on the first page and she can read one page per minute.

Emma is on the fifth page and she can read one page every three minutes.

Part A)

We can write an equation for Ashley. Let m represent the amount of minutes that has passed.

Since she is already one the first page, our initial value is 1.

She reads one page every minute. So, after m minutes, she would have read m pages.

Therefore, our equation is:

[tex]p=m+1[/tex]

Where p is the total pages read after m minutes.

Then after five minutes, Ashley will be on the:

[tex]p=(5)+1=6[/tex]

Ashley will be on the sixth page after five minutes.

Part B)

Since Emma reads one page every three minutes, we can say that she reads 1/3 of a page every minute.

Since she started on page five, her equation is:

[tex]\displaystyle p=\frac{1}{3}m+5[/tex]

Part C)

So, both of their pages read must be equivalent. Therefore:

[tex]\displaystyle m+1=\frac{1}{3}m+5[/tex]

Solve for m. Subtract 1/3m from both sides:

[tex]\displaystyle \frac{2}{3}m+1=5[/tex]

Subtract 1 from both sides:

[tex]\displaystyle \frac{2}{3}m=4[/tex]

Finally, multiply both sides by 3/2:

[tex]\displaystyle m=4\Big(\frac{3}{2}\Big)=6[/tex]

So, it will take six minutes before Ashley and Emma have read the same number of pages.

Scott drinks 6 cups of water a day. How many fluid ounces of water does Scott drink? (2 points)

Group of answer choices

36 fluid ounces

48 fluid ounces

52 fluid ounces

68 fluid ounces if your right I give u a lot of points

Answers

There are 48 fluid ounces of water Scott drink.

Define the term ounces?

An ounce is a unit of measurement of weight or mass in both the US customary system and the British imperial system. In the US customary system, one fluid ounce of water weighs about 1.04 ounces (oz).

Each day, Scott consumes 48 fluid ounces of water.

To convert cups to fluid ounces, we need to multiply the number of cups by 8 (as there are 8 fluid ounces in one cup).

So, 6 cups of water is equal to:

6 cups × 8 fluid ounces per cup = 48 fluid ounces

Therefore, there are 48 fluid ounces of water Scott drink.

If ten additional eighth-grade students join the group. If the ratio of eighth students to sixth graders remains constant.

Let 'x' be the number of students who join the club in 6th grade. Then the equation is given as,

x / (2 × 10 + 10) = 6 / 10

Simplify the equation, then we have

x / (2 × 10 + 10) = 6 / 10

x / 30 = 3 / 5

x = 30 (3/5)

x = 18

The number of students 6th graders who will need to join the club will be 18.

Answers

Answer: C 30 it was correct on my test

The estimated probability that at least two of the puppies will be female is 60%.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Let heads (H) be the female puppy

Let tails (T) be the male puppy.

The simulation results are the sample spaces.

[tex](THTT, TTTH, TTHH, HTTT, TTTT, HHHH, HTHT, HHHT, THTH, THTH)[/tex]

⇒ [tex]n(s)=10[/tex]

The event is the probability that at least two of the puppies will be

female.

[tex]e=(TTHH, HHHH, HTHT, HHHT, THTH, THTH )\\[/tex]

⇒ [tex]n(e)=6[/tex]

The estimated probability that at least two of the puppies will be

female, [tex]P(e)=\frac{n(e)}{n(s)}[/tex]

⇒ [tex]P(e)=\frac{6}{10}[/tex]

⇒ [tex]P(e)=0.6[/tex]

Thus the percentage of the female puppies = [tex](0.6)(100)[/tex]

⇒ [tex]60\%[/tex]

Hence we can conclude that the estimated probability that at least two of the puppies will be female is 60%.

If the lion is the king of the jungle, then the polar bear is the king of the Arctic. Polar bears are majestic, powerful creatures that capture our imagination and are a living definition of wild. Unfortunately, polar bears habitat is changing so much that they may not survive in the wild beyond this century.Polar bears survival depends on sea ice. They swim from ice floe to ice floe in search of seals and walruses. However, climate change has caused the polar bears hunting habitat to shrink in size. Ice floes are smaller, farther apart and farther from shore, making it necessary for polar bears to swim great distances in their hunt for food. These long journeys are dangerous. An Alaska Science Center study found that bear cubs swimming after their mothers had a 45% death rate.The length of season in which polar bears can hunt has also decreased by almost three weeks in the past twenty years. The reason is that the ice sheets are freezing later and melting earlier. The shorter time for food hunting has caused weight loss and poor health in the polar bears. Their populations have dropped 20 to 40 percent in most areas.Some people argue that polar bears will adapt to a new lifestyle, eating alternative foods, such as dolphins trapped by ice pockets or Arctic goose eggs. But, according to Karyn Rode, a wildlife biologist in Alaska, these occasional creative meals arent going to be enough to save all of the polar bears.We may lose the polar bear, the wildest creature of the Arctic, because of habitat loss caused by climate change.
