Answer:

the center is (-2,3)

Step-by-step explanation:

The required graph that represents circle  (x + 2)² + (y - 3)² = 25  is given below in the image.

graph represents the circle (x + 2)2 + (y - 3)2 = 25 to determine.

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2

Standard form of the equation of circle = ( x - h ) ²+ ( x - y )² = r²
Where r is the circle's radius and h and k is the circle's center.
Given equation of the circle =  (x + 2)² + (y - 3)² = 25
where center is ( -2, 3 )
radius r = √25 = 5

While plotting a circle on a graph marks the center at ( -2, 3 ) radius. and draw the circle of radius 5 around the center ( -2, 3 ). The result is shown in the image.

Thus, the required graph that represents circle (x + 2)² + (y - 3)² = 25. is given below in the image.

Answer:

X = 12

Step-by-step explanation:

42 + 48 = 90 degree angle

4 x 12 = 48

Answer:

See below

Step-by-step explanation:

2x+4 / x^2-x-6

= 2(x+2)/(x-3)(x+2)

= 2/(x-3)

So the 2 expressions are equivalent

The values of x which make the expressions undefined are those values which make the denominators 0

For 2x+4/ x^2-x-6 they are X=3 and x= -2.

For 2/x-3 they are x =3.

Final answer:

Point P will be closer to B than to A because the ratio of the partition is 4/7 which is closer to B than the ratio of 3/7 to A.

Explanation:

To determine whether point P will be closer to A or B, we need to consider the ratio of the partition. In this case, the ratio is 3:4. This means that the segment from A to P is 3/7 of the total segment, and the segment from P to B is 4/7 of the total segment.

Since the ratio of the partition is closer to B (4/7) than to A (3/7), point P will be closer to B than to A.

For example, if the distance from A to B is 7 units, the distance from A to P will be 3 units (3/7 * 7) and the distance from P to B will be 4 units (4/7 * 7).

If point P partitions the directed line segment from A to B into the ratio 3:4, then P will be closer to A. The ratio 3:4 means that the segment AP is 3 parts long while segment PB is 4 parts long, making PB longer than AP. The entire segment AB is therefore divided into 7 equal parts, with point P falling 3/7 of the distance from A and 4/7 from B. Since 3/7 is less than 4/7, P is closer to A.

Answer:

The answer is A. 9x +4x^2 -5y

Step-by-step explanation:

In order to find the difference, subtract each terms.

in order for 5x to get to 14x you have to +9x

in order for -7x^2 to get to -3x^2 you have to +4x^2

and last, in order for 7y to get to 2y, you have to -5y

Hope it helps!

Answer:

The answer is A.

Step-by-step explanation:

The correct option is The mode for the students is 2 and the mode for the teachers is 4.

To determine the mode of a data set, one must identify the number(s) that appear most frequently. In the dot plot for the students, the number of siblings that appears most frequently is 2, as there are 7 dots above the number 2 on the number line. This makes 2 the mode for the students' data.

 For the teachers' data, the number of siblings that appears most frequently is 4, with 5 dots above the number 4 on the number line. Therefore, 4 is the mode for the teachers' data.

 Comparing the modes of the two data sets, we have:

- Mode for students: 2

- Mode for teachers: 4

The other options provided do not accurately reflect the modes of the data sets based on the given dot plots.

The population is the entire group of customers who bought tablets, totaling 570 people. The sample is the subset of 300 customers who were randomly chosen to receive the survey.

In the given scenario, an electronics store has conducted a survey among its customers who purchased tablets. To identify the population and the sample in this context, we look at the definitions of each term. The population is the entire group that is the focus of the study, while the sample is a subset of the population that is surveyed to represent the whole.

The population in this case includes all the customers who bought tablets during the previous month, which totals to 570 people. The sample is the group of customers who were selected to receive the survey. Since surveys were sent to 300 of these customers at random, the sample size is 300.

Therefore, the correct identification is: The population is 570. The sample is 300.

The given expression is

[tex]a_{k}=8+(k-1)2[/tex]

Where [tex]d=2[/tex] and [tex]a_{1}=8[/tex].

The number of stitches in the n row are expressed as

[tex]a_{n} =8+2n-2\\a_{n} =2n+6[/tex]

Therefore, the n row has [tex]2n+6[/tex] stitches.

Notice that the result is an expression, that is beacuse the problem is asking for a general solution, it's asking for the n row, which refers to certain row in general terms.

Answer:

D. 13

Step-by-step explanation:

well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-

x= -b±[tex]\sqrt{b^{2}-4ac}[/tex] /2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since [tex]\sqrt{13^{2}-4*1*(-30)[/tex] = [tex]\sqrt{289}[/tex] = 17. So b=13.

The prism has a volume of 5 cubic unit is option (C) [tex]1\frac{1}{4}[/tex] unit, 4 unit and 1 unit

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface

A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.

Here,

Volume of prism = l × w × h

Option 1

Volume = [tex](1\frac{1}{2})(3)(1) =\frac{9}{2}[/tex] cubic units

Option 2

Volume = [tex](2)(2)(1\frac{1}{2})=6[/tex] cubic units

Option 3

Volume = [tex](1\frac{1}{4})(4)(1)=5[/tex] cubic units

Option 4

Volume = [tex](2)(1)(2)=4[/tex] cubic units

Hence, The prism has a volume of 5 cubic unit is option (C) [tex]1\frac{1}{4}[/tex] unit, 4 unit and 1 unit

Step-by-step explanation:

1.5x + 5y = 1152    

x = 4y – 2

We can substitute the second equation into the first equation

Which one-variable linear equation can be formed using the substitution method?

1.5(4y-2) +5y = 1152  

Distribute

6y -3 +5y = 1152

Combine like terms

11y-3 = 1152

Add 3 to each side

11y-3+3 = 1152+3

11y = 1155

Divide each side by 11

11y/11 = 1155/11

y = 105

How many $5 raffle tickets were sold?

105 5 dollar tickets were sold

Now we need to find the number of 1.50 tickets

Which equation can be used to determine how many $1.50 raffle tickets were sold?

x = 4y – 2

x = 4(105) -2

   =420-2

   = 418

How many $1.50 raffle tickets were sold?

418    $1.50 tickets were sold

Answer:

11y = 1155

$5 raffle tickets: 105

x = 4(105) - 2

$1.5 raffle tickets: 418

Step-by-step explanation:

1.5x + 5y = 1152    

x = 4y – 2

1.5(4y - 2) + 5y = 1152

6y - 3 + 5y = 1152

11y = 1155

y = 105

x = 4(105) - 2

x = 418

Rounded to the nearest thousandth: ≈45.479

Step-by-step explanation:

The formula for finding area using circumference is

[tex]\frac{c^2}{4\pi }[/tex]

c=23.9"

[tex]\frac{23.9^2}{4\pi }[/tex]

Since we're using 3.14 for pi, multiply 4 by 3.14, and continue from there.

[tex]\frac{23.9^2}{4(3.14)} = \frac{571.21}{12.56} = 45.47850318[/tex]

but we don't use that big number! We round to the nearest thousandth!

≈45.479

Answer:

46 inches^{2}

Step-by-step explanation:

The formula for the area of a circle is [tex]\pi r^{2}[/tex]

To work this out you would first need to divide 23.9 by pi to find out diameter.

Then you would divide the diameter by 2 to find the radius. Then you would multiply pi by the radius squared.

1) Divide 23.9 by [tex]\pi[/tex].

[tex]23.9/\pi=7.608[/tex]

2) Divide 7.608 by 2.

[tex]7.608/2=3.804[/tex]

3) Multiply pi by the radius squared.

[tex]\pi *3.804^{2} =45.4601526[/tex]

4) Round To nearest whole number.
