Answer:

ΔABC ~ ΔDEF

Step-by-step explanation:

If the given triangles ΔABC and ΔDEF are similar,

Their corresponding sides will be proportional.

[tex]\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}[/tex]

By substituting the measures of the given sides,

[tex]\frac{4}{2}=\frac{6}{3}=\frac{2}{1}[/tex]

2 = 2 = 2

Since, corresponding sides of both the triangles are proportional, both the triangles will be similar.

Answer: m=0

Step-by-step explanation: simplify each individual expression first. The left side of the equation is equal to -12m-6, and the right side is equal to 30m-6. Then together, it equals to -12m-6=30m-6. The -6 cancel each other out. M=0

Step-by-step explanation: Plato

15 represent the car travled 15 miles / gallons.

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

We have been given that -

 y = 15 * x

Where y = the distance and

x = the number of gallons of gas to cover that distance.

A common unit of capacity in English-speaking countries, equal to four quarts, the U.S. standard gallon being equal to 231 cubic inches (3.7853 liters), and the British imperial gallon to 277.42 cubic inches (4.546 liters).

Consider the units:

y[miles] = 15[??] * x[gallons]

15[??] = y[miles] / x[gallons]

[??] = [miles] / [gallons]

So the units of the parameter 15 must be [miles / gallon] to convert the gallons to miles.

Therefore 15  represents the miles / gallon for the vehicle.

Answer:

Katherine will rent at least 64 movies and 20 games to make a profit

Step-by-step explanation:

The given parameters are;

The amount for which she rents games = 4

The amount for which she rents movies = 4

The number of games and movies she most rent to make profit = 84

The number of games she ≤ 20

Let x represent the number of games, let y represents the number movies, we have;

x + y ≥ 84

x ≤ 20

64 ≤ y ≤ 84

[tex]\boxed {\boxed {\sf 102.1 \ meters}}[/tex]

Step-by-step explanation:

Let's assume the tree forms a right angle with the ground.

The distance from the tree to the man is 18 meters. The angle of elevation, which is 80 degrees, is the angle from where the man is to the top of the tree. We want to find the height of the tree, which we can call x.

Let's draw a diagram. (not to scale)

We can use sine (opposite/hypotenuse), cosine (adjacent/hypotenuse) or tangent (opposite/adjacent). We base the sides off of the elevation angle.

x is opposite the elevation angle and 18 is adjacent to the angle. So, we must use tangent.

[tex]tan(\theta)=opposite/adjacent[/tex]

The angle (θ) is 80. The opposite is x. The adjacent is 18.

[tex]tan(80)=x/18[/tex]

Now, solve for x by isolating it.

x is being divided by 18. The inverse of division is multiplication. Multiply both sides of the equation by 18.

[tex]18*tan(80)=x/18*18[/tex]

[tex]18*tan(80)=x[/tex]

[tex]18*5.67128182=x[/tex]

[tex]102.0830728=x[/tex]

Round to the nearest tenth. The 8 in the hundredth place tells us to round up.

[tex]102.1\approx x[/tex]

The height of the tree is about 102.1 meters.

In order to solve for x , we use the trigonometric function cosine

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be ΔABC , where ∠B = 90°

Let the side AB be x

So , the adjacent side = x

The angle of the triangle ∠A is = 72°

So , θ = 72°

The hypotenuse AC = 8

And , by trigonometric relations , we get

cos θ = adjacent / hypotenuse

Substituting the values in the equations , we get

cos 72° = x / 8

Multiply by 8 on both sides , we get

x = cos 72° × 8

Now , cos 72° = 0.30901

Substituting the value of cos 72° , we get

x = 0.30901 × 8

x = 2.472

Hence , the value of x is determined by cosine function

Answer:

The height of the kite is approximately 278.6 feet

Step-by-step explanation:

The length of Jason's Kite string, l = 325 feet

The angle of elevation of the kite string, θ = 58°

The height of Jason's hand, h = 3 feet above the ground

Therefore, we have;

The height of the kite = The vertical component of the length of the kite string + The height of Jason's hand above the ground

The height of the kite = l × sin(θ) + h

Substituting the values, we get

The height of the kite = 325 × sin(58°) + 3 ≈ 278.6 (which is obtained by rounding the answer to the nearest tenth)

The height of the kite ≈ 278.6 feet.

Answer:

A. 1733 scooters

Step-by-step explanation:

To get x for minimum value of C bar, set derivative = 0

We Find our x.

C(x) = 600+ 0.05x + 0.0002x^2

We need average cos per unit

So divide by x both sides

C(x) / x = 600/x + 0.05x + 0.0002x

c(x)/c = Ç(x)

Therefore, Ç(x) = 600/x + 0.05x + 0.0002x

Now differentiate both side with x

dÇ(x)/dx = 600/x^2 + 0 + 0.0002

To find x for minimum Ç(x)

Set dÇ(x)/dx = 0 => -600/x^2 + 0.0002 = 0

=> x^2 = 600/0.0002

x^2 =3000000

x = √3000000

x = 1732.05

x = 1733

We do this to undo the "minus 2" or "subtract 2" that is happening to the variable f. Addition is the opposite of subtraction.

Answer: A. f(x) = (x - 1)²

Step-by-step explanation:

The value of x in the equation (m^5/6) (m^1/6)^7 = m^x is 2

The exponents of numbers are added when the numbers are multiplied, subtracted when the numbers are divided, and multiplied when raised by still another exponent: a^m×a^n = a^(m+n); a^m÷a^n = a^(m−n);

(am)ⁿ = a^mn.

Given an equation, (m^5/6) (m^1/6)^7 = m^x

Using the law of exponent, we get,

(m^5/6) (m^1/6)^7 = m^5/6*m^7/6

= m^(5/6+7/6)

= m^12/6

= m^2

Hence, the value of x in the equation (m^5/6) (m^1/6)^7 = m^x is 2
