I Need HelpCenter? Radius?

Answers

Answer 1

Answers:

Center = (1, 5)

Radius = 3

===========================================================

Work Shown:

[tex]x^2+y^2-2x-10y+17 = 0\\\\(x^2-2x)+(y^2-10y)+17 = 0\\\\(x^2-2x+0)+(y^2-10y+0)+17 = 0\\\\(x^2-2x+1-1)+(y^2-10y+25-25)+17 = 0\\\\(x^2-2x+1)+(y^2-10y+25)+(-1-25+17) = 0\\\\(x-1)^2+(y-5)^2-9 = 0\\\\(x-1)^2+(y-5)^2 = 9\\\\(x-1)^2+(y-5)^2 = 3^2[/tex]

----------------------

Explanation:

The idea is to complete the square for the x and y terms separately.

Notice the jump from step 3 to step 4 has the first 0 turn into 1-1, and the second 0 turn into 25-25. This is to help complete the square for each part.

The x^2-2x+1 factors to (x-1)^2 and y^2-10y+25 factors to (y-5)^2

Once we reach the last step, we have something in the form [tex](x-h)^2+(y-k)^2 = r^2[/tex]

Center = (h,k) = (1,5)

Radius = r = 3

Write the equation for a parabola with a focus at (-3,-5)(−3,−5)left parenthesis, minus, 3, comma, minus, 5, right parenthesis and a directrix at x=-7x=−7x, equals, minus, 7.

Answers

Answer:

(y + 5)² = -16(x + 5)

Step-by-step explanation:

We are told the focus is at (-3, -5)

Directrix is at x = -7

This is a horizontal parabola and thus the general equation is;

(y - k)² = -4p(x - h)

Where;

(h, x) is the coordinate of the vertex.

The axis where the point where the axis of symmetry meets the directrix is at; (-7, -5) since directrix is at x = -7

Thus, coordinates of vertex is;

(-7 + (-3))/2, (-5 + (-5))/2

> (-5, -5)

Thus, equation is;

(y - (-5))² = -4p(x - (-5))

(y + 5)² = -4p(x + 5)

Where p is the distance from vertex to directrix. Thus;

p = -(-7 - (-3))

p = -(-7 + 3)

p = 4

Thus;

(y + 5)² = -4(4)(x + 5)

(y + 5)² = -16(x + 5)

Answer:

(y + 5)² = -16(x + 5)

Answers

Answer:

11x^2y^3 - 4xy^2

Step-by-step explanation:

(4x^2y^3 - 2xy^2 - 2y) - (-7x^2y^3 + 6xy^2 - 2y)

Combine like terms

4x^2y^3 - -7x^2y^3 = 11x^2y^3
Two negative signs together makes addition!

Combine like terms

2xy^2 - 6xy^2 = -4xy^2

Combine like terms

-2y - 2y = 0
We don’t have to include the zero

Now add 11x^2y^3 with -4xy^2 together

11x^2y^3 - 4xy^2

Therefore, the answer is: 11x^2y^3 - 4xy^2

Find The Surface Area Of The Prism

Answers

Answer:

190cm²

Step-by-step explanation:

there is 2 types of sides on this. the top and bottom are the same, the front, back, left, and right are the same.

We first calculate the surface area of the top and bottom.

5x5=25

now we multiply that by 2 because the top and bottom are the same

25x2=50

now we look at the remaining 4 sides. the sides on these are 7 and 5 so we do

7×5=35

since we have 4 sides, we multiply the answer by 4

4×35=140

we add the sums together

140+50=190cm²

Answer:

190 cm^2

Step-by-step explanation:

The formula for the surface area of a rectangular prism is:

2 (lw + hl + hw)

Use the formula with the given dimensions of the prism:

2 (5 x 5) + (7 x 5) + (7 x 5)

= 2 (25 + 35 + 35)

= 2 (95)

= 190

So the SA of the rectangular prism is 190 cm^2

what is the slope of a line perpendicular to y=-(7)/(4)x

Answers

Answer:  4/7

This is because the original line has slope -7/4. We flip the fraction and the sign, ie take the negative reciprocal, to get the perpendicular slope.

Flipping the fraction goes from -7/4 to -4/7. Then it flips to positive to get 4/7

Notice that multiplying the original and perpendicular slopes together gets us -1

(-7/4)*(4/7) = -1

This applies to any pair of perpendicular lines as long as neither line is vertical and neither is horizontal.

Answer:

[tex]\frac{4}{7}[/tex]

Step-by-step explanation:

Given

y = - [tex]\frac{7}{4}[/tex] x ( in the form y = mx , where m is the slope )

slope m = - [tex]\frac{7}{4}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{7}{4} }[/tex] = [tex]\frac{4}{7}[/tex]

200 students in total

Step-by-step explanation:

Mr.Cruz is the director of an after-school program. He says that 170 students, or 85% of the students in his program, went on to attend college. A parent wants to know the total number of students in the program.

?/T = 85%

Where T = Total

85% = 170 students

Set-up the dimensions like this!

part/whole = part/whole

170/T = 85%/100

Multiply 170 by 100

170 • 100 = 17000

Then divided by 85

17000 divided by 85 = 200

In a class test, (+2) marks were given for every correct answer and (–1) mark was
deducted for every incorrect answer. Rashmi answered all the questions and scored 30
marks. She gave 20 correct answers. Jashpal also answered a few questions and scored
–10 marks. He gave 5 correct answers. How many questions did Rashmi and Jashpal
attempt incorrectly?

Answers

Answer:

Rashmi attempted 10 questions incorrectly while Jashpal attempted 20 questions incorrectly

Step-by-step explanation:

Marks awarded for each correct answers = +2

Marks deducted each incorrect answer = -1

The number of questions Rashmi answered = All the question

Rashmi's score = 30

The correct answers Rashmi gave = 20

The number of questions Jashpal answered = A few questions

Jaspal's score = -10 marks

The number of correct questions Jashpal answered = 5

Let x represent the number of incorrect questions, for Rashmi, we have;

20×2 + x × (-1) = 30

x = 20×2 - 30 = 10

The number of questions Rasmi attempted incorrectly, x = 10

The number of questions Jashpal attempted incorrectly is given as follows;

5×2 + x × (-1) = -10

∴ 10 - x = -10

x = 10 + 10 = 20

The number of questions Jashpal attempted incorrectly, x = 20.

The two dot plots below show the heights of some sixth graders and some seventh graders: The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 1.7. Approximately how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders

Answers

Answer:

The number of times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders is approximately 1.4

Step-by-step explanation:

From the question, the mean absolute deviation (MAD) of the sixth graders = 1.2 and that of the seventh graders = 1.7

The variability in the heights of the sixth graders = 1.2

The variability in the heights of the seventh graders = 1.7

To calculate how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders, we will divide the variability of the seventh graders by the variability of the sixth graders

That is, 1.7/ 1.2 = 1.4167 ≅ 1.4

Hence, the number of times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders is approximately 1.4

Given:

Diameter of the hole = 30 cm

To find:

The area of the hole.

Solution:

The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:

[tex]r=\dfrac{30}{2}[/tex]

[tex]r=15[/tex]

Area of a circle is:

[tex]A=\pi r^2[/tex]

Putting [tex]\pi = 3.14[/tex] and [tex]r=15[/tex] in the above formula, we get

[tex]A=(3.14)(15)^2[/tex]

[tex]A=(3.14)(225)[/tex]

[tex]A=706.5[/tex]

Therefore, the area of the hold is 706.5 square cm.
