Recall from Intermediate Algebra that two non-vertical lines are perpendicular if and only if they have negative reciprocal slopes. That is to say, if one line has slopem1and the other has slopem2thenm1 · m2 = −1.Please note that a horizontal line is perpendicular to a vertical line and vice versa, so we assumem1 ≠ 0andm2 ≠ 0.Below, you are given a line and a point which is not on that line. Find the line perpendicular to the given line which passes through the given point.

Answer:

1/2

1/3

6

1/6

Step-by-step explanation:

When we are finding the opposite of a scale factor, the scale factor is always the reciprocal. E.g. From S to R, the scale factor is 3, so from R to S, the scale factor is 1/3 so:

1. From T to S, it's the reciprocal of the scale factor (2) so 1/2

2. From S to R, it's the reciprocal of the scale factor (3) so 1/3

3. From R to T, is the from a figure to a figure to a figure so we can multiply the two scale factors (2 and 3) to get 6

4. From T to R, that's the opposite of R to T, so it's the reciprocal of the scale factor from R to T (6) so 1/6

Answer:

$4.46

Step-by-step explanation:

$60- 24.32= $35.68

So $35.68=8 bags of potatoes.

Then ÷8 to find 1 bag.

$35.68 ÷8 = $4.46

$4.46=1 BAG

The value of the function f(x) at x = - 2 is equivalent to 32.

Given is that the average rate of change of the function f(x) on the interval -2 is less than or equal to [x] which is less than or equal to 4 is -3.5.

In the range of {- 2 ≤ x ≤ 4}, the rate of change of f(x) is -3.5. This means we can write -

r = {f(4) - f(-2)}/(4 + 2)

f(4) = 11 and [r] = - 3.5. So, we can write -

- 3.5 = {11 - f(-2)}/6

11 - f(-2) = -3.5 x 6

11 - f(-2) = - 21

f(-2) = 11 + 21

f(-2) = 32

Therefore, the value of the function f(x) at x = - 2 is equivalent to 32.

Answer:

  17.74

Step-by-step explanation:

The fraction is easily converted to one with a denominator of 100 (a power of 10):

  [tex]\dfrac{37}{50}=\dfrac{37\cdot 2}{50\cdot 2}=\dfrac{74}{100}=0.74[/tex]

Then the number of interest is ...

  17 37/50 = 17 74/100 = 17.74

Answer:

The common ratio of the geometric sequence is -4

Step-by-step explanation:

Geometric Sequence

A geometric sequence is defined as a series of numbers that follow a fixed pattern: Each term equals the previous term times a fixed number called the common ratio. The recursive formula is:

[tex]a_n=a_{n-1}*r[/tex]

Where r is the common ratio.

We are given three terms of a geometric sequence:

18,-72,288,...

To find the common ratio, just divide each term by the previous term:

[tex]\displaystyle r=\frac{-72}{18}=-4[/tex]

Make sure it's a fixed number and test with the third term:

[tex]\displaystyle r=\frac{288}{-72}=-4[/tex]

Since both numbers coincide, the common ratio of the geometric sequence is -4

Answer:

y=-x+3

Step-by-step explanation:

The y-intercept is at 3 and you can see it has a slope of -1

The equation of line will be y = -x + 3.

It is given that in the graph, line is passing through some points at x-axis and y-axis.

We have to find the fully simplified intercept of the line.

What is the general equation of a line ?

The equation of a line is y = mx + c , where m is the slope of the line and c is a constant.

We have the x-intercept (3,0) and y-intercept (0,3) on the graph.

Slope of these line through these points will be ;

m = (y2-y1) / (x2-x1)

m= (3-0) / (0-3)

m= 3/-3

m= -1

Also , we will get the value of c = 3 .

The equation of line after putting the value of m and c will be ,

y = -x + 3

Thus, the equation of line is y = -x + 3

Answer:T = 0.6

Step-by-step explanation:Simplifying

3t + -5 = 0

Reorder the terms:

-5 + 3t = 0

Solving

-5 + 3t = 0

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + 3t = 0 + 5

Combine like terms: -5 + 5 = 0

0 + 3t = 0 + 5

3t = 0 + 5

Combine like terms: 0 + 5 = 5

3t = 5

Divide each side by '3'.

t = 1.666666667

Simplifying

t = 1.666666667

Answer:

t = 5/3

t = 1 2/3

Step-by-step explanation:

Hi !

3t - 5 = 0

3t = 0 + 5

3t = 5

t = 5/3

t = 1 2/3

Good luck !

Answer:

(1) The cost formula is: y = $19,050 + $12·x.

(2) The cost of moving materials if 340 moves are made is $23,130.

(3) 82.81% of the variability in moving cost is explained by the number of moves.

Step-by-step explanation:

The computer output for the regression analysis of 80 data points is as follows:

Intercept:  $19,050

Slope: 12

Coefficient of correlation: 0.91

Standard error:  $220

(1)

The general formula of regression equation is:

y = a + b·x

Here,

a = intercept

b = slope

The cost formula is:

y = $19,050 + $12·x

(2)

Predict the cost of moving materials if 340 moves are made as follows:

[tex]y = 19050 + 12\cdot x\\=19050+12\times 340\\=19050+4080\\=23130[/tex]

Thus, the cost of moving materials if 340 moves are made is $23,130.

(3)

The coefficient of determination R² specifies the percentage of the variance in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).

The coefficient of determination R² can be computed by squaring the correlation coefficient value.

[tex]R^{2}=(r)^{2}=(0.91)^{2}=0.8281[/tex]

Thus, 82.81% of the variability in moving cost is explained by the number of moves.

Answer:

a

 Mutually exclusive

b

Not Mutually exclusive

c

Not Mutually exclusive

d

Not Mutually exclusive

Step-by-step explanation:

From the question we are told that

The number of bolt is n = 12

The event that all the bolt are torqued correctly is A

The event that the 3rd bolt is not torqued correctly is B

The event that exactly one bolt is not torqued correctly is C

The event that the [tex]4^{th}[/tex] and [tex]8^{th}[/tex] are torqued correctly is D

Generally for an event to be mutually  exclusive it means that both event can not occur at the same time

    Considering a  

      The  A and  B are mutually exclusive because they can not occur at the same time

    Considering b  

 The  event B and D are not mutually exclusive because they can occur at the same time

    Considering c

 Event  C and  D are not mutually exclusive because they can occur at the same time

    Considering d

   Event       B and  C are not mutually exclusive because they can occur at the same time

Step-by-step explanation:

Step-by-step explanation:

The way to approach the problem is this

After one year she has 2000*1.05

After two years she has the money from the last year plus interest, so she has 2000*1.05*1.05

After t years she has 2000*1.05

Step-by-step explanation:

Consider two points on a curve, (xᵢ, yᵢ) and (xᵢ₊₁, yᵢ₊₁).  The distance between them can be found with distance formula:

d = √((xᵢ₊₁ − xᵢ)² + (yᵢ₊₁ − yᵢ)²)

d = √((Δx)² + (Δy)²)

Factor out Δx:

d = √(1 + (Δy/Δx)²) Δx

Adding up the distances from i=1 to i=n, the total arc length can be approximated as:

s ≈ ∑ᵢ₌₁ⁿ √(1 + (Δy/Δx)²) Δx

Taking the limit as n approaches infinity, we get the exact value of s:

s = lim(n→∞) ∑ᵢ₌₁ⁿ √(1 + (Δy/Δx)²) Δx

Which can be written as a definite integral:

s = ∫ₐᵇ √(1 + (dy/dx)²) dx

Step 2: Distribute negative

4x² - 3x + 1 - 3x² + 5x - 4

Step 3: Combine like terms (x²)

x² - 3x + 1 + 5x - 4

Step 4: Combine like terms (x)

x² + 2x + 1 - 4

Step 5: Combine like terms (constants)

x² + 2x - 3

Answer:

6x-6

Step-by-step explanation:

5x-(6-x)

First you distribute the negative to (6-x) which makes -6+x, then you just subtract that from 5x which makes 5x-6+x then you just simplify into 6x-6.
