Find the area of triangle XYZ​

Answer:

option C I think

Step-by-step explanation:

I remember learning about this last year

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x - 2 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then

y = - 3x + c ← is the partial equation

To find c substitute (4, - 7) into the partial equation

- 7 = - 12 + c ⇒ c = - 7 + 12 = 5

y = - 3x + 5 → D

Trejo is correct, because if you know the x-intercepts, y-intercepts, domain, and range of a function then you automatically know the x- intercepts, y-intercepts, domain, and range of its inverse.

A relation between a set of inputs having one output each is called a function.

Given that;

Trejo says that if you know the x-intercepts, y-intercepts, domain, and range of a function then you automatically know the x- intercepts, y-intercepts, domain, and range of its inverse.

But, Hilary disagrees, She says you know the intercepts but that is all you know for sure.

Now,

We know that;

In a function, If if you know the x-intercepts, y-intercepts, domain, and range of a function then you automatically know the x- intercepts, y-intercepts, domain, and range of its inverse.

Thus, The Trejo is correct.

Answer:

C

Step-by-step explanation:

a is wrong because residuals are solved using y and not x

b is wrong because a residual closer to 0 would be more accurate, but f is less accurate than g

c is right because residuals are solved using y and a more accurate residual would be closer to the real answer's y value

Answer:

2.24$

Step-by-step explanation:

Answer:

find 3 consecutive numbers such that twice the first , 3 times the second and 4 times the third together make 191 ?

Let n-1,n and n+1 be three consecutive numbers.

Given

2(n-1)+3n+4(n+1)=191

2n-2+3n+4n+4=191

9n+2=191

9n = 189

n = 21

So, n-1=20 and n+1=22

So the answer is 20,21,22

The study of graphs, which are mathematical constructions used to represent pairwise relationships between things, is known as graph theory in mathematics. In this context, a graph is made up of vertices connected by edges.

In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to linked and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other forms of graphs.

Straight line graphs called linear graphs are used to show the relationship between two quantities. This graph makes it easier to show a result as a collection of straight lines. The term "linear" simply means a straight line; curves, dots, bars, etc. are not used.

Answer:

I think is would be 32√

Answer:

To form a right triangle, one of the sides of the triangle must be the hypotenuse and the other two sides must be the legs. The hypotenuse is the longest side of a right triangle and the side opposite the right angle. In this case, the side with length 5x is the hypotenuse. Therefore, the sides with lengths 3x and 24 must be the legs.

We can use the Pythagorean Theorem to determine the value of x that will make this a right triangle. The Pythagorean Theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, we have:

5x^2 = 3x^2 + 24^2

Solving for x, we get:

x = sqrt(24^2/(5^2 - 3^2)) = sqrt(576/16) = 6

Therefore, a value of x = 6 will make this a right triangle.

The 3 different polynomial equations are linear polynomial equations, quadratic polynomial equations, and cubic polynomial equations.

A polynomial equation is one where a polynomial is set equal to zero. i.e., it is an equation created with variables, non-negative integer exponents, and coefficients together with operations and an equal sign.

A polynomial equation is always like "polynomial = 0". Algebraically, it is of the form p(x) = aₙ xⁿ + aₙ₋₁ xⁿ⁻¹ + ... + a₁ x¹ + a₀x⁰ = 0, where

aₙ, aₙ₋₁, ...., a₁, a₀ are coefficients and all these numbers are real numbers.

'x' is the variable.

p(x) means "polynomial in terms of variable x"

'n' is a non-negative integer, it is the degree of p(x).

Answer:

how are you working on a saturday night?

Step-by-step explanation:

4.5 is the length of each part in feet. This can be solved by using the concept of feet.

foot, plural feet, any of a wide range of ancient, medieval, and modern linear measurements (often 25 to 34 cm) based on the length of the human foot and used only in English-speaking nations, where it typically consists of 12 inches or one-third yard.

The foot measured [tex]11^{\frac{1}{42}[/tex] inches in antiquity. The typical man's foot measures 12 inches in length nowadays.

Given that:

The length of the wooden board is given as = 108 inches.

As it is cut in 2 equal parts, it becomes: 108/2 = 54 inches in each

We have to calculate the length of each part in feet, so divide 54 by 12.

As we know,

12 inches = 1 feet

Thus, 54 inches = 54/12 feet = 4.5 feet

So, the length of each part is 4.5 feet.

Step-by-step explanation:

Given

[tex]\frac{-4(-8.625+2d)}{-8} +3=10[/tex]

Lets solve for [tex]d.[/tex]

Start on the left side with the fraction.

Factor -4 out of -8.

[tex]\frac{-4(-8.625+2d)}{-4(2)} +3=10[/tex]

Cancel the common factor of -4.

[tex]\frac{-8.625+2d}{2} +3=10[/tex]

Subtract 3 from both sides.

[tex]\frac{-8.625+2d}{2} =7[/tex]

Multiply both sides by 2.

[tex]\frac{-8.625+2d}{2} *2=14[/tex]

Cancel the common factor of 2.

[tex]-8.625+2d=14[/tex]

[tex]2d-8.625=14[/tex]

Add 8.625 to both sides.

[tex]2d=22.625[/tex]

Divide both sides by 2.

Answer:

9% interest rate

Step-by-step explanation:

Investment = principal = $4000

Interest amount = $1080

Period, t = 3 years

Simple interest = principal * rate * time

1080 = 4000 * rate * 3

1080 = 12000 * rate

Rate = 1080 / 12000

Rate = 0.09

The rate as a percentage = 0.09 * 100% = 9%

Answer:

41 1/4 and 15

Step-by-step explanation:

So for the first question, we know that a single inch of thread has 16 1/2 bolts. We know that there are 2 1/2 inches of thread.

To find the total anount of bolts in the thread, we can multiply 2 1/2 by 16 1/2:

2 1/1*16 1/2 = 41 1/4

That is our first answer.

For our next answer, we know that a book is 1 7/8 inches big.

The bookshelf is 28 1/8 inches big.

To find how many of the 1 7/8 inch big books can fit in the 28 1/8 inch big bookshelf, we can divide 28 1/8 by 1 7/8:

28 1/8/1 7/8

=

15

So our 2nd answer is 15.

Answer:

its sqrt (50)

Step-by-step explanation:

The triangle has a right angle, therefore we can use the Pythagorean theorem to find the hypotenuse. According to the theorem the sum of the squares of both other sides is equal to the square of the hypotenuse.

We have 5^2+5^2=c^2

=> 25+25=c^2

=> 50=c^2

Therefore c or the missing side is equal to sqrt(50)
