Answer 1

Answer:

ST = 52

SW = 54

WV = 54

Step-by-step explanation:

Because TW is a median line, that means that SW and WV are the same length. So, SW = WV or:

2x + 30 = 5x -6

We can then rearrange to have all the x's on one side like so:

2x - 2x + 30 = 5x -2x -6

30 = 3x -6

30 + 6 = 3x -6 +6

36 = 3x

Then, we divide both sides by 3 to find x by itself:

[tex] \frac{36}{3} = \frac{3x}{3} [/tex]

12 = x

To finish, replace x with 12 in each equation:

ST = 12 + 40

ST = 52

SW = 2(12) + 30

SW = 24 + 30

SW = 54

WV = 5(12) -6

WV = 60 -6

WV = 54

on a unit circle, what is tan for coordinates (-√2/2, √2/2)?

a.) -1
b.) -√2/2
c.) 1
d.) √2/2
e.)√2

Answers

Answer:

Step-by-step explanation:

Remember that tangent is the ratio of sine over cosine.

[tex]\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}[/tex]

In the unit circle:

Sine refers to the y-coordinate. Cosine refers to the x-coordinate.

Our x-coordinate is -√2/2 and our y-coordinate is √2/2.

So, substitute -√2/2 for cosine and √2/2 for sine. This yields:

[tex]\tan(\theta)=\frac{\sqrt2/2}{-\sqrt2/2}[/tex]

Since the numerator and the denominator are the same save for a negative, we can cancel them:

[tex]\tan(\theta)=-1[/tex]

So, our answer is A.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.

Answers

Answer:y = -2/3x + 490

Step-by-step explanation:

2x +3y = 1470

Slope intercept form definition: y = mx + b is the slope-intercept form of a line where m is the slope and b is the y-intercept.

2x + 3y = 1470

2x + 3y -2x = 1470 - 2x - Subtract 2x from both sides

3y = 1470 - 2x - Simplify

3y/3 = 1470/3 - 2x/3 - Divide both sides by 3

y = -2/3x + 490 - Simplify

-⅔ is the slope and 490 is the y-intercept

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement.

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement. 6 + (–8) Which statement could describe Ahmed’s movement?

Given the expression

6+(-8)

Let's denote upward movement in the elevator as positive and downward movement as negative.

+6 means that Ahmed rides 6 floors above in the elevator (since +be means upward movement in the elevator)

-8 means that from that 6th floor, he then moves 8 floors downwards in the elevator. In other to determine the floor Ahmed is, we can evaluate the given expression:

= 6+(-8)

Note that -×+ = -, hence the expression becomes;

= 6-8

= -8+6

= -2

This means that Ahmed is 2 floor below or down the elevator.

Answer: He moved 6 floors up, then moved 8 floors down. So he is now 2 floors below ground level.

I hope this helps.
