Answers

Answer 1

9514 1404 393

Answer:

  13

Step-by-step explanation:

The distance between the points is the magnitude of their difference.

  |(-2-3i) -(3+9i)| = |-5 -12i| = √(5² +12²) = 13

The distance between the point is 13 units.

the vertex for f(x)=-7(x+8)^2+ 3 is the minimum for that function ture or false

Answers

Answer:Do you what it in vertex because if you do the answer is (-8,3)

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = - 7(x + 8)² + 3 ← is in vertex form

with (h, k) = (- 8, 3 )

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

Here a = - 7 < 0 , thus

(- 8, 3 ) is a maximum

Jeffrey and Frank walk at different speeds.Frank’s walking speed can be represented by the equation y=85x, where is the time in minutes and y is the distance in meters. The distance Jeffrey walked over the time is shown on the graph below

Answers

Answer:

Option (C)

Option (C)

Option (A)

Step-by-step explanation:

Part A.

Frank's walking speed can be represented by the equation.

Equation representing the speed is,

y = 85x

[tex]\frac{y}{x}=85[/tex]

Therefore, walking speed of Frank = 85 meters per minute.

Option (C) will be the answer.

Part B.

Distance walked over the time by Jeffrey is given by the graph attached.

Equation for the speed will be,

y = [tex](\frac{400}{5})x[/tex]

y = 80x

Therefore, walking speed of Jeffrey = 80 meters per minute

Difference in the speed of Frank and Jeffrey = 85 - 80 = 5 meters per minute.

Jeffery walks 5 meters per minute slower than Frank.

Option (C) will be the answer.

Part (C)

Distance traveled by Frank in 16 minutes,

y = 85(16) = 1360 meters

Time taken to travel the same distance by Jeffrey will be,

1360 = 80x

x = [tex]\frac{1360}{80}=17[/tex] meters per minute

Option (A) will be the answer.

A baker in 70 minutes iced 40 cupcakes and in 49 minutes he iced 28 cupcakes what is the constant of proportionality? express your awnser in decimal form.

Answers

Answer:

1 cupcake is made in 1.75 minutes.

1.75 minutes

Step-by-step explanation:

Divide 70 by 40 = 1.75.

49/28=1.75

The constant of proportionality of the given data is 0.57.

What is constant of proportionality?

The constant of proportionality is the ratio of two proportional values at a constant value.

Now it is given that,

Time taken for icing 40 cupcakes = 70 minutes

∴ Icing of cupcakes in 1 minute = 40/70

                                                    = 0.57

Time taken for icing 28 cupcakes = 49 minutes

∴ Icing of cupcakes in 1 minute = 28/49

                                                    = 0.57

constant of proportionality = 0.57

Thus, the constant of proportionality of the given data is 0.57.

Step-by-step explanation:

You need to start with the 2x inside the parenthesis

If you put 4 in place of x you get 8

Triangle PQR with coordinates P(3,-4), (6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically. What will
be the coordinates of P'Q'R'?

Answers

Answer:

(0, 2), (3, 5) and (3, 0)

Step-by-step explanation:

Since, Points P(3,-4), Q(6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically.

Therefore,

P' (3 - 3, - 4 +6) = P' (0, 2)

Q'(6 - 3, - 1 + 6) = Q'(3, 5)

R'(6 - 3, -6 + 6) = R'(3, 0)

Thus, the coordinates of P'Q'R are (0, 2), (3, 5) and (3, 0).

Answer:

P'(0, 2), Q'(3, 5), R'(3, 0)

Step-by-step explanation:

Given

Points P(3,-4), Q(6, -1), R(6, -6) Translation: x -3, y + 6

New points:

P'(3 - 3, -4 + 6) = P'(0, 2)Q'(6 - 3, -1 + 6) = Q'(3, 5)R'(6 - 3, -6 + 6) = R'(3, 0)
