Answer:

right 5 units

Step-by-step explanation:

given f(x) then f(x ± a) is a horizontal translation of f(x)

• if + a then a shift of a units left

• if - a then a shift of 5 units right

f(x) → g(x) = (x - 5)² with a = - 5

then f(x) is shifted 5 units right to obtain g(x)

Step-by-step explanation:

The given dimensions are related by the perimeter formula for a rectangle.

Let w represent the width in meters. Then (w+5) represents the length. These values can be put into the perimeter formula, which can be solved to find w.

  P = 2(L +W)

  82 = 2((w+5) +w) . . . . fill in for L and W

  41 = 2w +5 . . . . . . . . divide by 2

  36 = 2w . . . . . . . . . subtract 5

  18 = w . . . . . . . . . divide by 2. This is the width.

  w+5 = 18+5 = 23 . . . . find the length

The length of the rectangle is 23 m; the width is 18 m.

Answer:

The reciprocal of an undefined slope is 0.

Answer:

x = 8

z = 15

y = 118°

Step-by-step explanation:

First, we know that these are similar. That means that if we know which angles correspond to each other, those are equal, and the sides that correspond to each other have a common ratio. I went ahead and rotated PQRS so that it visually aligns with WXYZ -- that image is attached. We can do this because similar shapes must have the same angles, so aligning the angles works here. Using that, we can see that, based on the angles, QR matches up with XY, WZ matches up with PS, and so on.

We can then say that there is a common ratio between the corresponding sides.

WZ/PS = XW/PQ = ZY/RS = 9/6 = 12/x = z/10

9/6 simplifies to 3/2, so we have

3/2 = 12/x

multiply both sides by x to no longer have it as a denominator

3 * x / 2 = 12

multiply both sides by 2 and divide both sides by 3 to isolate x

x = 8

3/2 = z / 10

multiply both sides by 10 to isolate z

z = 15

In the corresponding figures, we can see that y matches up with ∠WXY. Thus, the two angles are equal and y = 118°

Answer:

m<U=70

Step-by-step explanation:

we know that the measure of the out side angle is equal to the measure of the 2 inside angles, so 120-50=70

Answer:

∠ U = 70°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ RVU is an exterior angle of the triangle , then

∠ U + 50° = 120° ( subtract 50° from both sides )

∠ U = 70°

We calculate the volume of the cuboid :

60 x 100 x 40 = 240000 cm^3

If every bag has 8000 cm^3 of grit, he will need 240000 : 8000 = 30 bags

Every bag cost £2.50, so he will need £2.50 x 30 = £75

Since he only has £70, he doesn't have enough money to buy the grit.

Step-by-step explanation:

Given:

Sale for $20

Sale: 10% off

New cost of the fidget spinner

Solve:

$20 × 10% = 2 {Discount Price/off price}

$20 - 2 = $18 {New cost of the fidget spinner}

Thus, the new cost of the fidget spinner

Step-by-step explanation:

The correct answer is 224

Answer:

2 1/6

Step-by-step explanation:

Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.

4 1/2 -> 9/2

6 2/3 -> 20/3

Next, make the denominators the same by multiplying each fraction by the denominator of the other.

9/2 * 3 = 27/6

20/3 * 2 = 40/6

Then you can subtract the numerators because the denominators are the same:

40/6-27/6= 13/6

Then you can convert to a mixed fraction if need be.

Using it's concept, it is fond that the estimate for the ratio of red to blue beads is of 91:79.

The ratio between two amounts a and b is given by a divided by b, that is:

[tex]\frac{a}{b} = a:b[/tex]

In this problem, considering Charlotte's and Harry's beads, there are 81 + 10 = 91 red beads and 9 + 70 = 79 blue beads, hence the ratio is given by:

91:79.

Answer:

6x +15

Step-by-step explanation:

To solve for the perimeter of the triangle, we need to find the length of each side.

(a +b)² = a² +2ab +b²

Let's factorise the expression for the area of the square:

Area of square

= 4x² +20x +25

= (2x +5)²

Since area of square= side ×side, length of a side of the square is the square root of its area. We are also given that the side of the square is AB.

(AB)²= (2x +5)²

Taking the square root of both sides:

AB= 2x +5

The perimeter is the sum of the lengths of all of its sides.

Perimeter of the triangle

= 3(AB)

= 3(2x +5)

= 6x +15

The speed the fan will turn is 625 rpm

Since they fan and the pulley ahve the same linear speed v = rω where

Then

r₁ω₁ = r₂ω₂ where

Making ω₁ subject of the formula, we have

ω₁ = r₂ω₂/r₁

Substituting the values of the variables into the equation, we have

ω₁ = r₂ω₂/r₁

ω₁ = 2 in × 1250 rpm/4 in

ω₁ = 1250 rpm/2

ω₁ = 625 rpm

So, the speed the fan will turn is 625 rpm
