Line A passes through points (-1, 5) and (3, -1). Line B passes through points (7, 2) and (6, -1).
At what point does line A intersect line B?

Answers

Answer:

          At (5, -4)

Step-by-step explanation:

The slope of a line that passes through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The equation of the line that passes through given point with a slope of m:  

y - y₁ = m(x - x₁)

Line A:

 [tex]m=\dfrac{-1-5}{3-(-1)}=\dfrac{-6}4=-\dfrac32[/tex]

[tex]y-5=-\frac32(x+1)\\\\y=-\frac32(x+1)+5[/tex]

Line B:

 [tex]m=\dfrac{-1-2}{6-7}=\dfrac{-3}{-1}=3[/tex]

[tex]y-2=3(x-7)\\\\y=3(x-7)+2[/tex]

Point of intersect means the same coordinates x and y.

So:

       [tex]3(x-7)+2=-\frac32(x+1)+5\\\\3x-21+2=-\frac32x-\frac32+5\\\\3x-19=-\frac32x+\frac72\\\\6x-38=3x+7\\\\6x+3x=7+38\\\\9x=45\\\\x=5\\\\y=3(5-7)+2=3(-2)+2=-4[/tex]

Anna bought a potted plant online. It cost $3.4 5plus 20% shipping and handling.What was the total cost

Answers

Answer:

Total cost = $4.08

Step-by-step explanation:

Given the following data;

Selling price = $3.4

Shipping and handling fee = 20%

To find the total cost;

First of all, we would determine the extra fee;

Extra fee = 20/100 * 3.4

Extra fee = 68/100

Extra fee = $0.68

Now, we can solve for the total cost using the formula below;

Total cost = selling price + extra fee

Total cost = 3.4 + 0.68

Total cost = $4.08

The polygons to the right are similar. Find the value of each variable

Answers

Answer:

y = 7

x = 24

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides are equal

For the bigger triangle we have a total 48; so for the smaller we have x

For the bigger, we have 14, so for the smaller, we have y

Mathematically;

25/x = 50/48

x * 50 = 25 * 48

x = (25 * 48)/50

x = 24

For y;

25/y = 50/14

y = (25 * 14)/50

y = 7

A ship travels 200 km west from port and then 240 km due south before it is disabled. Illustrate this in a vector diagram. Use trigonometry to find the course that a rescue ship must take from port in order to reach the disabled ship.

Displacement of the ship

The displacement of the ship from the initial position is calculated as follows;

d² = 200² + 240²

d² = 97,600

d = √97,600

Oscar is planning to paint his house. For stability, the foot of his 17-foot ladder should be placed 4 feet from the house. How far up the side of the house will the ladder reach?

Answers

Answer: The side of the house will the ladder reached by ladder = 16.52 feet

Step-by-step explanation:

House is standing vertical on the ground.

By placing ladder, it will become a right triangle with hypotenuse as ladder.

By Pythagoras theorem,

[tex](hypotenuse)^2=(perpendicular)^2+(base)^2[/tex]

i.e.

[tex](17)^2=(Height \ of\ wall\ reached\ by\ ladder)^2+4^2\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=289-16\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=273\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)=\sqrt{273}\approx16.52[/tex]

Hence, the side of the house will the ladder reached by ladder = 16.52 feet (approx)

Answers

Standard deviation is 7.35

Cindy got a 100

(100-84)/7.35=2.2

D FINAL ANSWER

Based on the test scores of the students, Cindy's z-score on the science test is 2.2

How to determine the z-score of Cindy?

We start by calculating the mean of the scores using:

Mean =Sum/Count

So, we have:

Mean = (75 + 80 + 90 + 100 + 75 + 85 + 80 + 80 + 90 + 85)/10

Mean = 84

Using a statistical calculator, the standard deviation is:

Standard deviation = 7.35

The z-score is then calculated using:

z = (x - mean)/standard deviation

Cindy's score is 100.

So, we have:

z = (100 - 84)/7.35

Evaluate

z = 2.2

Hence, Cindy's z-score on the science test is 2.2

Who wants to be the first of the generations born in space to set foot on a real planet?Maria waited for someone else to speak or raise their hand. Next to her, Allen just stared at the floor of the lander muttering, Not me, not me.She glanced at Lily, who Maria had always known to be fearless, but Lily bit her lip and turned away. Javier looked positively gray, and the twins buried their faces in their hands. Someone would have to be first.

Ill do it, Captain, she mumbled as she slipped out of her harness and rose out of her seat. Maria couldnt shake the feeling of trepidation as she stood and watched the doors of the lander slide open.A NEW WORLDA burst of air hit Maria in the face. She scrunched up her nose as an unfamiliar assortment of odors hit her nostrils. Some smelled sweet, some disgusting, and some were just strange. There were never strange smells on the ship; everything was always the same there. What was it going to be like to live where things changed? The rest of the children gathered around the opening as she climbed down the ladder, and Maria tried to smile as she met their worried eyes. Then, suddenly, something crunched underneath her boots; she was standing on the surface of the planet, and it felt nothing like the smooth metallic halls that shed known all her life.Without letting go of the ladder, she turned around to look at the world around the lander. The soil was full of shapes and textures; there were some small, grainy pieces, then larger clumps that she could break with the toe of her boot. One piece was hard and smooth, and she let go of the ladder to pick it up. Captain, she called, I think Ive found a rock!The air was moving, and long, thin, green things bowed and danced. Grasses, Maria whispered to herself, remembering the videos in her science lessons. She let go of the ladder and took soft, slow steps and realized her arms and legs felt like they were full of lead. Natural gravity, she whispered to herself. She started to walk a little more quickly, getting used to the new sensation. She was doing what others had previously thought impossibletaking steps on a new world.A creature with gossamer wings landed on her nose, and she crossed her eyes trying to get a good look at it. Something small and furry scurried across her feet as she spun in a slow circle. Inspired, she ran as fast as she could across the foreign soil; shed never seen somewhere so big, and it was thrilling. Suddenly, a deep, low sound echoed around her. Thats the call of a hornbeast, Captain Curran shouted from the bottom of the ladder. Maria glanced back and saw that he was helping her friends take tentative first steps in the new world.
