Answer:

15

Brainliest, please!

Step-by-step explanation:

r = kp/(st)

p = 12, t = 2, s = 5, r = 18

18 = k(12)/(2)(5)

18 = 12k/10

12k = 180

k = 15

Answer:

the range is from 6 to -4 (both inclusive)

Step-by-step explanation:

the domain is all values of x for which the function is defined and the range is all values of y for which the function is defined hence the domain is -3 to -11 and the range is 6 to -4

Yes they are. Explanation provided below.

Step-by-step explanation:

Two shapes are congruent when they are the same shape and size. Its obvious that both are rectangles and if we look at the grid, we can see that both rectangles are 2 by 4. Since they both have the same shape and size, they are in fact congruent.

Answer:

2x = 40

Step-by-step explanation:

Let the number be x

Twice means 2 time

2 × x

2x

The product is 40

2x = 40

Step-by-step explanation:

Twice a number is forty

Let the number be x, then

2×x=40

2x=40

x=40/2

x=20

Step-by-step explanation:

subtitle values of x one by one:

a)f(2.5)=1/2.5-2

f(2.5)=1/0.5

f(2.5)=2

b)Now x=1.75

f(1.75)=1/1.75-2

f(1.75)=1/-0.25

f(1.75)=-4

c)x=2

f(2)=1/2-2

f(2)=1/0

f(2)=infinity

d)something divided by zero is equal to infinity that is exteremly large value

Step-by-step explanation:

i didn't use the distance formula, instead i used the pythagrean theorum. i counted the units for the legs, and made three smaller triangle and solved them to find the lengths of the hypotenuse and the added the three of those together to find the perimiter of the original triangle

Answer:

The united nations flag the translation can be any of the blue triangles and the reflection if the flag itself as it is symmetrical

Step-by-step explanation:

The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

If you're reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)

Therefore, The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

Answer:

Length=13.07 and Breadth=1.07

Step-by-step explanation:

Area=l*b

14=(2x+5)(2x-7)

14=4x^2-4x-35

4x^2-4x-49=0

Using quadratic formula, we have x=(1±5sqrt(2))/2 but as length can't be negative, so x=(1+5*sqrt(2))/2

Length=13.07 and Breadth=1.07
