40 scaled to a factor of 0.25

Answers

Based on the number being scaled and the scale factor, the value of 40 when scaled to a factor of 0.25 is 10.

How to scale a quantity?

When a mathematical problem is given that requires that you scale a certain number by a certain scale factor, you scale that number by multiplying the number by the scale factor.

In this case, the number is 40 and the scale factor is 0.25. When the number is scaled by a factor of 0.25 therefore, we get:

= Number x Scale factor

= 40 x 0.25

= 10

In conclusion, 40 scaled to factor of 0.25 is 10.

5. What is the domain of the function y = 3x - 4 when the range is (-7, 2, 8, 14}?
A.
{-1, 0, 1, 2}
Y = 3x-4
B.
{-1, 2, 4, 6}
C. {-25, -29, -33, -37}
D. (17, 21, 25, 29}
4413

Answers

the domain will be D = { - 1 , 2 , 4 , 6 } for the function y = 3 x - 4.

We are given a function:

y = 3 x - 4

Now we are also given the range as:

R = { -7 , 2 , 8 , 14 }

For y = - 7, we get the value of x as:

- 7 = 3 x - 4

3 x = - 7 + 4

3 x = - 3

x = - 3 / 3

x = - 1

For y = - 2, we get the value of x as:

2 = 3 x - 4

3 x = 2 + 4

3 x = 6

x = 6 / 3

x = 2

For y = 8, we get the value of x as:

8 = 3 x - 4

3 x = 8 + 4

3 x = 12

x = 12 / 3

x = 4

For y = 14, we get the value of x as:

12 = 3 x - 4

3 x = 14 + 4

3 x = 18

x = 18 / 3

x = 6

So, the domain will be:

D = { - 1 , 2 , 4 , 6 }

Therefore, the domain will be D = { - 1 , 2 , 4 , 6 } for the function y = 3 x - 4.

Answer:

  (c)  (-30)⁴

Step-by-step explanation:

You want to simplify the product (-6)⁴×(5)⁴.

Exponents

An exponent is an indicator of repeated multiplication:

  (-6)⁴ = (-6)(-6)(-6)(-6) . . . . . . the factor -6 is repeated 4 times

  (5)⁴ = (5)(5)(5)(5)

Then the product is ...

  (-6)⁴ × (5)⁴ = (-6)(-6)(-6)(-6)(5)(5)(5)(5)

The commutative and associative properties of multiplication let you regroup this to ...

  (-6)(5)×(-6)(5)×(-6)(5)×(-6)(5) = (-30)(-30)(-30)(-30)

Using the exponent to signify repeated multiplication, this can be written as the equivalent ...

  (-30)⁴

__

Additional comment

This product has an even number of minus signs, so will be positive. It is fully equivalent to ...

  30⁴.

Find the perimeter of triangle ABC with vertices A(1,-6), B(1,-3), and C(-4,-6). Round to the nearest hundredth if necessary

Answers

The perimeter of triangle ABC is equal to 13.83.

Perimeter

The perimeter of a geometric figure is the sum of its sides. Thus, for a triangle, for example, the perimeter is S1+S2+S3, where S represents the dimension of each side.

Given Data

Coordinates Points:  A(1,-6), B(1,-3), and C(-4,-6)Triangle

In this question are given the coordinates of each vertex triangle. Then, you should plot these coordinates  A(1,-6), B(1,-3), and C(-4,-6) in a graph. See the attached  image.

From the plotted points, it is possible to note that  the triangle is a right triangle and its sides are: AB=3 and AC=5. For finding the side BC, it is necessary to apply the Pythagorean Theorem: (hypotenuse)²= (side1)²+(side2)². Thus,

(hypotenuse)²= (side1)²+(side2)²

(BC)²=(AB)²+(AC)²

(BC)²=(3)²+(5)²

(BC)²=9+25

(BC)²=34

BC=[tex]\sqrt{34}[/tex]=5.83

Now, you have all information to calculate the perimeter of the given triangle.

perimeter = AB+AC+BC = 3 +5 +5.83 =8+5.83=13.83

Answers

Answer:

  (-16, 0)

Step-by-step explanation:

You want the other endpoint of the segment with midpoint (-6, 4) and endpoint (4, 8).

Setup

The midpoint of a line segment has coordinates that are the average of the coordinates of the end points.

  M = (A +B)/2 . . . . midpoint M of segment AB

  2M = A +B . . . . . multiply by 2

  B = 2M -A . . . . . solved for the other end point

  B = 2(-6, 4) -(4, 8) . . . . substitute given coordinates

Solution

  B = (2(-6) -4, 2(4) -8) = (-16, 0)

The other end point of the segment is (-16, 0).
