find the center and radius of the circle whos equation is (x+5)^2+(y-3)^2=9
9514 1404 393
Answer:
center (-5, 3)
radius 3
Step-by-step explanation:
Compare the given equation to the standard form equation of a circle:
(x -h)² +(y -k)² = r² . . . . . . circle with center (h, k) and radius r
This shows us that ...
-h = +5 ⇒ h = -5
-k = -3 ⇒ k = 3
r² = 9 ⇒ r = √9 = 3
Then the circle center is (h, k) = (-5, 3), and the radius is r = 3.
f(x)= x^2. what is g(x)?
A. g(x) = 1/4x^2
B. g(x) =1/4x^2
C. g(x) =4x^2
D. g(x) = 1/2x^2
Answer: g(x)=x/3^2
Step-by-step explanation:
We are given that:
f(x)=x²
We have to find g(x)
Since, we are given that g(3)=1
Hence, we will proceed by the options.
1. g(x)=
at x=3 g(x)=1/9
Hence, this option is incorrect.
2. g(x)=3x²
at x=3, g(x)=27
Hence, this option is incorrect.
3. g(x)= x²/3
at x=3, g(x)=3
Hence, this option is incorrect.
4. g(x)=
at x=3, g(x)=1
Hence, this option is correct

The middle school is purchasing shoes for its basketball team. The cost of
each pair of shoes is $42. The total cost, t,is proportional to s,the number
of pairs of shoes ordered. Which of the following equations models this
proportional relationship? *
Answer:
9s = 378t
is the same as (9 x 42) etc...
Step-by-step explanation:
I don't have the choice of answers of what is being said as proportional but an example is here below of what numbers are multiples of 42 and therefore found its proportion this way.
10s = 420t (10 x 42)
9s = 378t (9 x 42) etc...
8s = 336t
7s = 294t
6s = 252t
5s = 210t (5 x 42)
4s = 168t etc....

1 A boat travels at an average speed of 15 km/h for 1 hour.
a Calculate the distance it travels in one hour.
b At what average speed will the boat have to travel to cover the
same distance in 2 hours?
Answer: 15km, 7.5kmh
Step-by-step explanation:
a. Distance travelled = speed * time = 15* 1 =15km
b. Distance = 15
time = 2hrs
Speed = distance/time = 15/2 = 7.5kmh

Question 2. In 2015, a Pew Research poll determined that 56% of teenagers go online several times a day.
You question a sample of 150 area high school students about their online habits. Describe the sampling distribution for the sample proportion, for samples of size 150, of high school students who go online several times a day. You should include a picture that approximates the sampling distribution, and label at least five tick marks in that drawing. Round to the nearest tenth of a percent.
b. You find that, in your sample, 94 of the high school students go online several times a day. Assuming the percentage obtain from Pew, is your result unusual, as defined in class? Justify your answer with a z-score.
Answer:
84 students go online several times a day

A moderately active man weighing 175 pounds should consume no more than 687 calories per day from fat sources. If fat contains 9 calories per gram, what is the maximum number of grams of fat he should consume? Give me a whole number or decimal rounded to one decimal place. Thanks! Expert only please.
According to the question, therefore, the maximum number of grams of fat he should consume will be 76.3 grams.
Step-by-step explanation:-Directly divide 687 by 9 as both are fat content. Therefore, by dividing them, we get to know about how grams of fat can be consumed.

The arithmetic mean of ten numbers is -10. If the sum of six of the numbers is 100, what is the arithmetic mean of the other 4?
Answer:
56
Step-by-step explanation:
Arithmetic mean is simply the sum of the all the number present divide by the total number.
From the question, we obtained the following information:
The arithmetic mean = 5.6
Total number present = 10
Sum of the numbers =?
Arithmetic mean = sum of the numbers / total number
Sum of the numbers = arithmetic mean x total number
Sum of the numbers = 5.6 x 10 = 56
The sum of the other four numbers is equivalent to -200.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that the arithmetic mean of ten numbers is -10. The sum of six of the numbers is 100.
We can write -
{a + b + c + d + e + f + g + h + i + j}/10= - 10
{a + b + c + d + e + f + g + h + i + j} = - 10 x 10
{a + b + c + d + e + f + g + h + i + j} = - 100 .... Eq{1}
and
{a + b + c + d + e + f} = 100 .... Eq{2}
We can write Eq{1} as -
{a + b + c + d + e + f} + {g + h + i + j} = - 100
100 + {g + h + i + j} = - 100
{g + h + i + j} = - 100 - 100
{g + h + i + j} = - 200
Therefore, the sum of the other four numbers is equivalent to -200.

During hockey practice, Jason skates 180 yards in 20 seconds.
Based on his average speed, approximately how many yards will he skate in the next 15 seconds?whoever answers first will be marked the brainliest
The approximate yards Jason will skate in the next 15 seconds is 135 yards
Given that :
Number of yards skate in 20 seconds = 180 yards
The rate per second cannbe calculated thus :
Rate = distance / time Rate = 180 / 20 = 9 yards per secondThe distance skate in 15 seconds will be:
Distance = time × rate Distance = 15 × 9 = 135 yardsTherefore, Jason will skate 135 yards in the next 15 seconds.

Sorry if I didn't understand the question right-
Answer:
[tex]\frac{49}{6}[/tex]
Step-by-step explanation:
The inverse of [tex]\frac{3}{7}[/tex] is [tex]\frac{7}{3}[/tex].
The inverse of [tex]\frac{2}{7}[/tex] is [tex]\frac{7}{2}[/tex].
Now we multiply:

Answer:
|3x +5| = 3x +1|3x +5| = x -1Step-by-step explanation:
The left-side expression will not intersect the right side expression if the slopes are the same and the y-intercepts are chosen appropriately. An example is ...
|3x +5| = 3x +1
The right-side line stays below the left-side V, so doesn't intersect.
__
You can choose the slopes to be different, also, if you make the intercepts such that the right-side line does not intersect the left-side V. An example of that is ...
|3x +5| = x -1
__
Graphs of the left- and right-side expressions are shown in the attachment.

Sam is moving bags of soil from a loading dock into a storeroom. The topsoil weighs 40 pounds per bag, and the mulch weighs 20 pounds per
bag. The cart Sam uses to move the bags can only carry up to 480 pounds.
Which graph represents the number of topsoil bags and mulch bags that Sam can move in a single trip?
Answer:
The answer would be the A (I included a picture to show you which one it is)
Step-by-step explanation:
Options D and E are out because it clearly says " bags can only carry up to 480 pound" and those are saying it can hold more than 480
Options B and C have a dashed line. If it has a dashed line that means that it is < or > and it is not because it says "up to" up to means it CAN hold exactly 480
So the only right answer would be Option A
Answer:
A
