Which graphs represent functions?

Answers

Answer:

A. Only graph B and D

Step-by-step explanation:

Hi, to answer this question we have to analyze the options given:

A function has only one output value (y) for each input value.(x)

In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).

So, the correct option is:

A. Only graph B and D

If a vector A⃗ has the following components, use trigonometry to find its magnitude and the counterclockwise angle it makes with the +x axis: Ax = 9.00lb , Ay = 5.00lb

Answers

The vector magnitude is 10.29lb and the vector direction is 150.9⁰.

Vector:

As per the given question:

Ay = 5.00 \ lb\n\nAx = 9.00 \ lb\n\n

To find:

magnitude and direction=?

Solution:

Vector representation of the given value:

\to (9i + 5j)

Calculating the vector magnitude:

\to √((9)^2 +(5)^2)\n\n \to √(81+25)\n\n \to √(106) \n\n\to 10.29 \ lb

Calculating the vector direction:

When 90 < \theta < 180

Let's solve the value for \theta\n\n

\tan \theta = (y)/(x)\n\n\tan \theta = (5)/(9)\n\n\tan \theta =0.555\n\n\theta = \tan^(-1)(0.555555556) \n\n\theta= 29.1^(\circ)\n\n

\sin \theta lies in the second quadrant,

\to \theta = 29.1^(\circ) = 180 -29.1 = 150.9^(\circ)\n\n

Given:

1/8 x 4 = (1*4) / 8 = 4/8 = 1/4
1/4 x 3 = (1*3) / 4 = 3/4
3/8 x 2 = (3*2) / 8 = 6/8 = 3/4
1/2 x 3 = (1*3) / 2 = 3/2 = 1 1/2
5/8 x 1 = 5/8
7/8 x 1 = 7/8
3/4 x 1 = 3/4

Total number of tomatoes = 4 + 3 + 2 + 3 + 1 + 1 + 1 = 15 tomatoes
Total weight = 1/4 + 3/4 + 3/4 + 3/2 + 5/8 + 7/8 + 3/4

1/4 * 2/2 = 4/8
3/4 * 2/2 = 6/8
3/2 * 4/4 = 12/8

4/8 + 6/8 + 6/8 + 12/8 + 5/8 + 7/8 + 6/8 = 46/8 total weight in pounds

46/8 ÷ 15 tomatoes = 46/8 * 1/15 = 46/120 = 23/60 average weight per tomato

40 Jenny is buying gifts for her family. So far she has spent $45,95, and she has one more gift to buy. She started with a total of $60 to spend on all of her gifts Write an inequality that shows how much she can spend on the final gift

Answers

Greetings!

Answer:

x \leq 14.05

Step-by-step explanation:

First, to find the boundary we need to find the amount of money left, simply subtract the spent amount from the total:

60 - 45.95 = 14.05

Seeing as this is the amount, she can spend any amount up to and including 14.05, so we need an equal to or smaller than sign:

Let x be the value of the object:

x \leq 14.05

Which is the inequality!

A calculator is allowed on this question.For what value of the coefficient, C, will the equation have no solution?
HELP PLS HOW DO I DO THIS STEP BY STEP!!

Answers

Answer:

  C.  2/3

Step-by-step explanation:

You want the value of C that makes the equation have no solution.

  (3/4)(5 +(C/2)x) +2 = (x +7)/4

Simplify

A calculator is not needed to simplify the equation. We can start by multiplying both sides by 4.

  3(5 +(C/2)x) +8 = x +7

  15 +(3C/2)x +8 = x +7

  (3C/2)x +23 = x +7

No solution

This will have no solution if the coefficient of x is the same on both sides of the equal sign.

  3C/2 = 1

Multiplying by 2/3 gives ...

  C = 2/3

The value 2/3 for C will make the equation have no solution, choice C.

__

Additional comment

When C=2/3, the equation becomes one that reduces to ...

  (x +23)/4 = (x +7)/4 . . . . . no value of x will make this true.

Answer:

2/3

Step-by-step explanation:

3/4 * (5+ 2/3/2*x)+2 = x+7/4

Simplify

3/4(5+ 1/3x)+2 = x+7/4

15/4 + 1/4x +2 = x+7/4

23/4 + 1/4x = x+7/4

Cancel terms (multiply by 4 to get rid of 4)

23 + x = x + 7

23 = 7

false :)
