Answer 1
Answer:

The point-slope form of the equation for a line can be written as

... y = m(x -h) +k . . . . . . . for a line with slope m through point (h, k)

Your function gives

... f'(h) = m

... f(h) = k

a) The tangent line is then

... y = 5(x -2) +3

b) The normal line will have a slope that is the negative reciprocal of that of the tangent line.

... y = (-1/5)(x -2) +3

_____

You asked for "an equation." That's what is provided above. Each can be rearranged to whatever form you like.

In standard form, the tangent line's equation is 5x -y = 7. The normal line's equation is x +5y = 17.

Answers

Answer:

$12.80

Step-by-step explanation:

The cost to get 8 bottles of juice and 4 bags of chips will be:

= 8($.105) + 4($1.10)

= $8.40 + $4.40

= $12.80

The cost for x bottles of juice and y bags of chips will be:

= (1.05 × x) + (1.10 × y)

= 1.05x + 1.10y

Choose the graph of 3x + y = –2.

Answers

Answer:

Option (d) is correct.

Step-by-step explanation:

Given : Equation of line  3x + y = -2

We have to choose the correct graph for the given equation of line 3x + y = -2

Consider the given equation of line 3x + y = -2

We find the points that satisfies the equation of line and plot these to find the equation of line.

Put y = 1

We get

3x  + 1 = -2

3x = -2 -1 = -3

x = -1

also, put y = 4

We get

3x  +  4 = -2

3x = -2 -4 = - 6

x = - 2

also, when x = 0 , we get, y = -2

We get three points (-1, 1), (0,-2) and (-2, 4)

Now plot these point to obtain graph as shown below.

20. What is his total speed as he walks along the moving walkway?
21. Carlos turned around because he left his cell phone at a restaurant.
What was his speed as he walked against the moving walkway?

Answers

His speed was 2x² + 7x - 11 as he walked against the moving walkway.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

We are given that Carlos is walking on a moving walkway. His speed is given by the function

C(x) = 3x² + 3x - 4,

The speed of the walkway is W(x) = x² - 4x + 7.

The total speed as he walks along the moving walkway is;

x² - 4x + 7+ 3x² + 3x - 4,

= 4x² - x + 3,

Given Carlos turned around because he left his cell phone at a restaurant.

If he walked against the moving walkway

- x² + 4x - 7 + 3x² + 3x - 4,

2x² + 7x - 11

Well, for 20 you just add them, to get 4x^2-x+3. For 21, you do a substraction: 2x^2+7x-11. It'd take him quite some time (does this one even have zeros? :)) )

What is the mean of the data set? I got 177 when i added up the numbers but what would i divide 177 by?12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18

A.14.00

B.14.75

C.15.75

D.13.50

Answers

If you would like to know the mean of the data set, you can calculate this using the following steps:

The mean of the data set is the sum of all the data values divided by the number of these values.
  
12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18

12 + 17 + 16 + 10 + 20 + 13 + 14 + 14 + 12 + 12 + 19 + 18 = 177
the number of data values: 12
177 / 12 = 14.75

The correct result would be B. 14.75.

i have a question with this 'The vertices of Figure ABCD are A(1, 1), B(2, 3), C(4, 3), and D(5, 1). If Figure ABCD is reflected over the line y = –1, find the coordinates of vertex B’. Enter your answers in the boxes" i would be really happy if someone told me the answer

Answers

Answer:

(2, - 5)

Explanation:

The line y = -1 is horizontal: parallel to the y-axis.

The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:

Δy = 3 - ( - 1) = 4

When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change.  The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.

Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).
