Answer:

1. Jesús Colón is trying to debate weather or not to help the woman and her two young children. He thought it was a good idea because she was carrying a suitcase and a baby but at the same time he wasn't so sure because he was worried about what the woman would think and if she was racist or prejudice. He even was afraid that the woman would try talk to him in mean ways or to discriminate him just because he was both African and Puerto Rican.

2. Colón had his reputation at stake in this decision due to what the woman would do exactly. Since he didn't help the woman he regretted it and believed he should have helped her even if it would have costed him.

3. I believe he wrote this story to explain that simple actions can lead to a huge change in the future. For example if you see some one who is mean and they need help and you help them then that one mean person can become a really nice person in return just from your actions.

4. I would have helped the woman even though the circumstances because no matter my skin color, reputations, or the way i look i would help anyone because they may not know but deep down i am a good person. And you should not judge a book by its cover.

5. I would not care what others think even though i might fell that its not my place to do something i would do it anyway because nothing can change me. Words may be mean but they can not hurt me.

Find the perimeter of the figure to the nearest hundredth.

Answers

Answer: 90.75 mm

Step-by-step explanation:

Given

The radius of the hemisphere is 16 mm

length of the inclined sides are 20 mm

The perimeter of the figure is the sum of the length of two inclined sides and a semi-circle circumference

[tex]\Rightarrow \text{Perimeter P=}\dfrac{2\pi r}{2}+2\times 20\\\\\Rightarrow P=\pi \times 16+40\\\Rightarrow P=50.75+40\\\Rightarrow P=90.75\ mm[/tex]

Solve the system of equations and choose the correct ordered pair. 5x+2y= 19 4x - 3y - 6 A (3,5) B. (5-3) C. (5,3) D. (3,2)​

Answers

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

---------------------------

       23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

5x+2y =19

Substitute y=2

5x+2(2) =19

5x+4 = 19

Subtract 4 from each side

5x +4-4 =19-4

5x= 15

Divide by 5

5x/5 = 15/5

x=3

The solution is

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work

A linear function that represents the number of hot dogs purchased at a football game is compared to a different linear function that represents the time left in the game. Describe the key features of the functions that are needed to determine if these lines intersect.

Answers

Well if y1= m1x + b1

y2 = m2 x + b2

Lines are the same if m1 = m2 and b1 = b2 (they intersect in infinitely many points)
If b1 ≠ b2 and m1 = m2 then lines are parallel and do not intersect
If m1≠ m2 then lines will intersect at one point

The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.

Using the formula for the area of a triangle, area=1/2*base*height , write an expression for the area of ΔABC. This time, base your answer on the work you did in part E. Show your work. The graph so far is provided.

Answers

Did you ever get the answer?

I did mine but i don’t know if it’s correct (I haven’t submitted it yet)

Area = 1/2 * base * height

Base= b = 20

Height = BD = 9.05

Area = 1/2 * 20 * 9.05

Area = 90.5 units squared

The expression for the area of ΔABC will be A = 1/2 x CA x BD, and the area is 90.5 square units.

What is the area of the triangle?

The area of the triangle is given as

A = 1/2 x B x H

Where B is the base and H is the height of the triangle.

Then the expression for the area of ΔABC will be

A = 1/2 x CA x BD

A = 1/2 x 20 x 9.05

A = 90.5 square units
