Answer:

y + 5 = (1/3)(x - 6)

Step-by-step explanation:

Line p is perpendicular to line q, and therefore the slope of line p is the negative reciprocal of the slope of line q:  -1/3.

Starting with the point-slope formula y - k = m(x - h), we get

y + 5 = (1/3)(x - 6)

Answer: A) g(x) is shrunk horizontally by a factor of 1∕3 compared to ƒ(x).

Step-by-step explanation:

Given: f(x) 10x

g(x) =10(3x)

= f(3x)

Since, f(ax) is a horizontal compression when a> 1 by the factor of [tex]\dfrac{1}{a}.[/tex]

That means g(x) is shrunk horizontally by a factor of [tex]\dfrac{1}{3}[/tex] compared to ƒ(x).

So, the correct option is A) g(x) is shrunk horizontally by a factor of 1∕3 compared to ƒ(x).

Answer:

  43.96 in^2

Step-by-step explanation:

The net shows the areas of the parts of the cone, so you simply need to add them up to get the total surface area.

  31.4 in^2 +12.56 in^2 = 43.96 in^2

Answer:

43.96 in.2.

Step-by-step explanation:

The surface area of a cone is the triangular shape and its circular base.

In this case, the top of the cone is 31.4 inches squared in area, and the circular base is 12.56 inches squared.

So, the surface area of the cone is 31.4 + 12.56 = 43.96 inches squared.

Answer: {-7, 2}

Step-by-step explanation: This type of equation is called a polynomial equation and in order to solve for x, we would first factor the left side.

Notice that the left side of the equation is a trinomial in a special

form that can be factored as he product of two binomials.

As our first term for each binomial, we have the factors of x², x · x

and as the second term, we have the factors of -14 that add to 5.

In this case, the factors are +7 and -2.

So we have (x + 7)(x - 2) = 0.

If (x + 7)(x - 2) = 0, that means that either x + 7 = 0 or x - 2 = 0.

Solving for x in each equation, we have x = -7 or x = 2.

We can write our answer as the solution set {-7, 2}.

The solution of quadratic equation is,

⇒ x = - 7, 2

We have to given that,

An equation is,

⇒ x² + 5x - 14 = 0

We can factorized the above quadratic equation as,

⇒ x² + 5x - 14 = 0

⇒ x² + (7 - 2)x - 14 = 0

⇒ x² + 7x - 2x - 14 = 0

⇒ x (x + 7) - 2 (x + 7) = 0

⇒ (x + 7) (x - 2) = 0

This gives,

x + 7 = 0

x = - 7

x - 2 = 0

x = 2

Therefore, The solution of quadratic equation is,

⇒ x = - 7, 2

Question:

Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?

Choose 1 answer: 

[tex]A.\ |1.7 - 1/2|[/tex]

[tex]B.\ |1.7 -(-1/2)|[/tex]

C. None of the above

Answer:

[tex]B.\ |1.7 -(-1/2)|[/tex]

Step-by-step explanation:

Given

Numbers: 1.7 and -1/2

Required

Determine the distance

To calculate the distance, we start by calculating the difference between the given numbers;

[tex]Difference = 1.7 - (-1/2)[/tex]

Then, we calculate the distance;

In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;

Hence,

[tex]Distance = |Difference|[/tex]

Substitute [tex]1.7 - (-1/2)[/tex] for Difference;

[tex]Distance = |1.7 - (-1/2)|[/tex]

Hence, the correct option is B

The expression that represents the distance between 1.7 and -0.5 is given by |1.7 - (-0.5)| and this can be determined by using the arithmetic operations.

Given :

Numbers  --  1.7 and -0.5

The distance between two points 1.7 and -0.5 is given by:

Distance = 1.7 + |-0.5|

               = 2.2

Now, check all the options in order to determine the correct option:

A) |1.7 - 0.5|

Simplify the above expression.

|1.7 - 0.5| = 1.2

B) |1.7 - (-0.5)|

Simplify the above expression.

|1.7 - (-0.5)| = |1.7 + 0.5| = 2.2

Therefore, the correct option is B).

Answer:

It is not correct.

Step-by-step explanation:

If you plug 4 in for x, you get -2*4+5=13. This simplifies to: -8+5=13. This is an untrue statement since -8+5 is actually -3, not 13.

Hope this is helpful! :)

Answer:

undefined

Step-by-step explanation:

So with the following equation,

-2x + 5 = 13

we plug in 4 for x

-2(4) + 5 = 13

-2 * 4 = -8

-8 + 5 = 13

-8 + 5

-3 = 13

-3 is not 13 so it is undefined

Thus,

the answer is undefined.

Answer: z score is -19

Work Shown:

x = 22 is the raw score

mu = 60 is the mean

sigma = 2 is the standard deviation

z = (x-mu)/sigma = formula to find z scores

z = (22 - 60)/2

z = -38/2

z = -19

The z score of -19 means we are 19 standard deviations below the mean. Anything beyond 3 standard deviations is often considered unusual/rare as most of the data in the normal distribution is within 3 standard deviations (approximately 99.7% of the distribution)

Answer:

8.5 units

Step-by-step explanation:

x is the adjacent side, the side that's 19 units is the opposite side.

Given the adj and the opp sides, use tangent.

tanθ= opp/adj

tan 66°= 19/ x

x(tan66°)= 19

x= 19/(tan 66°)

x= 8.5 units (nearest tenth)

Answer:

XY = 24 units

Step-by-step explanation:

First of all, we need to some construction here.

Let us draw a line parallel to XY from point P towards OX, which cuts OX at point Q.

Please refer to the attached figure.

Now, Let us consider triangle OQP which is a right angled triangle, with

Hypotenuse, OP = 26 units

Height, OQ = OX - PY = 16  - 6 = 10 units

Base, PQ = ?

We can use pythagorean theorem here to find the value of PQ.

According to pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = PQ^{2} + OQ^{2}\\\Rightarrow 26^{2} = OQ^{2}+10^{2} \\\Rightarrow PQ^{2} = 26^{2}-10^{2} \\\Rightarrow PQ^{2} = 676-100 \\\Rightarrow PQ^{2} = 576\\\Rightarrow PQ= 24\ units[/tex]

Now, we can see that side PQ is equal to side XY.

[tex]\therefore[/tex] XY = 24 units is the answer.

Answer:

The number of students in each van = 14

The number of students in each bus = 43

Step-by-step explanation:

Let the number of students that can fill a van be v.

Let the number of students that can fill a bus be b.

The senior class at High School A rented and filled 13 vans and 9 buses with 569 students.

13 vans will have (13v) students

9 buses will have (9b) students

13v + 9b = 569

High School B rented and filled 14 vans and 3 buses with 325 students

14 vans will have (14v) students.

3 buses will have (3b) students.

14v + 3b = 325

Combining these two simultaneous equations

13v + 9b = 569

14v + 3b = 325

Solving simultaneously,

v = 14 students.

b = 43 students.

Step-by-step explanation:

Let the equation of the exponential function is f(x) = a(b)ˣ

Two points (-2, 4) and (-1, 2) lie on the graph,

For (-2, 4),

By substituting the values in the given function,

[tex]4=a(b)^{(-2)}[/tex]

[tex]4=\frac{a}{b^{2} }[/tex] ------(1)

For second point (-1, 2),

[tex]2=a(b)^{-1}[/tex]

[tex]2=\frac{a}{b}[/tex] -----(2)

Dividing equation (1) by equation (2),

Therefore, equation of the exponential function will be,

f(x) =

Option (A) will be the answer.

Step-by-step explanation:

Answer:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles are 12. So, we then know that a = 20.

(Root 15^2-9^2=12) (Root 12^2+16^2=20)

Another way is using the whole triangle. The step above used two triangles. The two triangles together makes a big right triangle, so we can again use the Pythagorean theorem. So, the answer again is 20.

(Root 25^2-15^2=20)

Step-by-step explanation:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles is 12. So, we then know that a = 20.

We have to find the value of ‘a’ using two different ways.

By the Pythagorean theorem,

By cross multiplication,

16(25) = a2

a2 = 400

Taking square root,

a = 20

Therefore, the length of the other side a = 20.

You can calculate the mean value by adding up the numbers and then dividing the result by the number of numbers. For instance, to find the mean value of 4, 1, 3, and 8, first, add up the numbers: 4+1+3+8=16 4 + 1 + 3 + 8 = 16.

Therfore=a2−b2.
