If the domain of the function f(x)=2x^2-8 is {-2, 3, 5}, then the range is

Answers

Answer 1

Answer:

{0, 10, 42}

Step-by-step explanation:

The Domain acts like x and the Range acts like y and f(x) = y

f(x) = 2x^2 - 8

f(-2) = 2(-2)^2 - 8

f(-2) = 2(4) - 8

f(-2) = 8 - 8

f(-2) = 0

f(3) = 2(3)^2 - 8

f(3) = 2(9) - 8

f(3) = 18 - 8

f(3) = 10

f(x) = 2x^2 - 8

f(5) = 2(5)^2 - 8

f(5) = 2(25) - 8

f(5) = 50 - 8

f(5) = 42

Find a formula for the transformation of reflection across the line l with equation y = -x.

Answers

Answer:

The rule or formula for the transformation of reflection across the line l with equation y = -x will be:

P(x, y) ⇒ P'(-y, -x)

Step-by-step explanation:

Considering the point

[tex]P(x, y)[/tex]

If we reflect a point [tex]P(x, y)[/tex] across the line [tex]l[/tex] with equation [tex]y = -x[/tex], the coordinates of the point P flips their places and the sign of the coordinates reverses.

Thus, the rule or formula for the transformation of reflection across the line l with equation y = -x will be:

P(x, y) ⇒ P'(-y, -x)

For example, if we reflect a point, let suppose A(1, 3), across the line [tex]l[/tex] with equation [tex]y = -x[/tex], the coordinates of point A flips their places and the sign of the coordinates reverses.

Hence,

A(1, 3) ⇒ A'(-3, -1)


Find the value of x that makes m || n

Answers

Answer:

a) 24

Step-by-step explanation:

To  make m//n,  the sum of co-interior angles (4x + 84) should be 180

4x + 84 = 180

        4x = 180 - 84

        4x = 96

         x = 96/4

The perimeter of the bedroom floor is 44 ft

Step-by-step explanation:

The Perimeter of a Rectangle

Given a rectangle of width W and length L, the perimeter is the sum of all four sides:

P = 2W + 2L

We know a rug of dimensions 6 ft x 10 ft is located at the center of a bedroom floor and there are 1.5 ft exposed on all four sides of the bedroom.

Adding this length to each side, we have the dimensions of the bedroom as:

6 + 1.5 + 1.5 = 9 ft

10 + 1.5 + 1.5 = 13 ft

Thus, the perimeter of the bedroom floor is:

P = 2*9 + 2*13 = 44 ft

The perimeter of the bedroom floor is 44 ft

Quadrilateral ABCD is translated to get quadrilateral A'B'C'D'. vertex A is at (-5,2) , and vertex A' is ay (2,-2), quadrilateral ABCD is translated blank..... if vertex B is at (-6,5), then vertex B is at​

Answers

Answer:

(-1,3)

Step-by-step explanation:

Given that the quadrilateral ABCD is translated to get quadrilateral A'B'C'D'. The vertex A is at (-5,2) is translated to vertex A' is at (2,-2).

The translation is x-direction, a, is the difference of x-coordinates of both the points, a=2-(-5)=2+5=7.

The translation is y-direction, b, is the difference of y-coordinates of both the points, b = -2-2 = -4.

As all the points are translated by the same magnitude as well as in the same direction, so by adding a to x and b to y coordinate of any points, the translated point can be determined.

The vertex of point B is (-6,5), so, the vertex of the point B' would be (-6+a, 5+b)=(-6+7, 5+(-4))=(-1,3).

Hence, the vertex of point B' is (-1,3).

A sum of money invested at the compound interest payable yearly has interest in
2 years and 4 years are Rs. 4,200 and Rs. 9282 respectively. Find the rate of
interest​

Answers

Answer:

49% and 30% respectively

Step-by-step explanation:

Step one:

Given data

Principal =  Rs. 4,200

Final Amount= Rs. 9282 respectively

time = 2 years and

time = 4 years

Required

The rate of interest for 2 and 4 years

Step two:

the compound interest formula is

A= P(1+r)^t

for 2 years

Substitute

[tex]9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2[/tex]

[tex]1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\[/tex]

the rate is 49%

For 4 years we have

[tex]9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4[/tex]

[tex]1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\[/tex]

the rate is 30%

Your company makes game parts using 3-D printers. One customer wants a circular game coin that is 2.0 centimeter across and 0.5 centimeters thick. You need to estimate the of plastic you will need for each arch of 50 coins. How many cubic centimeters is that, rounded up if necessary to be a multiple of 10 cubic centimeters?

Answers

Answer:

80 cm^3

Step-by-step explanation:

The computation of the number of cubic centimeters rounded up to 10 cubic centimeter is shown below

For any type coin,

r = d ÷ 2

= 2 ÷ 2

= 1 cm

l = 0.5cm

For making 1 coin, the plastic required would be = Volume of coin

= πlr^2

= 3.14 × 0.5 × 1 × 1

= 1.57cm^3

Now For 50 coins,

Plastic needed is

= 50 × 1.57

= 78.5cm^3

= 80 cm^3

D. 7

Answers

Answer:

A.1

Step-by-step explanation:

I did a check digit calculator and it said that this would be the check digit

The check digit is 1.

Step-by-step explanation:

The check digit on credit is calculated by the following step:

Mark each digit odd and even from the right side.Now multiply each digit at an even place with '2'.And if the number after multiplication is double-digit then add both the digit to obtain a single digit.Now add all the digits obtained in the previous step along with digits at odd places.To this sum obtained check by adding what digit it becomes next multiple of '10'.And that digit will be our check digit.

Given:

The creditcard number: 6424 9813 2720 008d

To find :

Check digit,d

Solution:

6424 9813 2720 008d

Marking odd and even places from right side:

(e:even place,o:odd place)

e,o,e,o     e,o,e,o     e,o,e,o     e,o,e,o

6 4 2 4     9 8 1 3     2 7 2 0     0 0 8 d

Multipling every even place digit with '2'.

12,4,18,2,4,4,0,16

If two digit number then add both digits to have single digit

12,4,18,2,4,4,0,16 → 1+2,4,1+8,2,4,4,0,1+6 → 3,4,9,2,4,4,0,7

Now adding all the digits obtained in prevoius step with digits at odd place:

(3+4+9+2+4+4+0+7)+(4+4+8+3+7+0+0)= 59

The next multiply of 10 can be obtained by adding 1 to '59' that is 60. So, the check digit will be'1'.

59+1 = 60

(60 is a multiple of the number '10'.)

The check digit is 1.

Ok so we will eliminate some numbers first. The width is 12, but the total on the perimeter is 24. 50-24 = 26

26 is not the length, so divide that by 2, and get 13
