What are the zeros of the following function?
y = x2 + x - 12
A.-4, 3
B.4, -3
C.-6, 2.
D.6, -2

Answers

answer: A, -4, 3

you set up the equation by making it equal to zero. so it’s x^2 + x - 12 = 0

then you solve for x

you do this by factoring. you do this by saying what multiplies to -12 and then adds up to 1 since your a times c is -12 and your b is 1

4 and -3 work. so we do (x+4) (x-3) = 0

(x+4) = 0 is -4
(x-3) = 0 is 3

so your answer is A, -4, 3

What is the slope of the line that contains the points (-2,5) and (6,-3)? O A. 1 O B. -8 O C. -1 O D. 8​

Answers

Answer:

-1

Step-by-step explanation:

Find the slope using the slope formula

m = (y2-y1)/(x2-x1)

    = (-3-5)/(6 - -2)

   = (-3-5)/(6+2)

   = -8/8

   = -1

Answer:

The answer is option C

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-2,5) and (6,-3)

The slope is

[tex]m = \frac{ - 3 - 5}{6 + 2} = - \frac{8}{8} = - 1[/tex]

We have the final answer as

- 1

an object is moving at a speed of 6 miles per month. express this speed in feet per hour. Don’t have to round anything up

Answers

Answer: 44 feet.

Step-by-step explanation: If the object is moving at a speed of 6 miles per month, that's 6 miles for every 720 hours at the very least. That's 1 mile for every 120 hours. That's 5280 feet for every 120 hours. The object is moving 44 feet every hour.

The speed of the object is 43.39 feet per hour.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 minute = 60 seconds

1 km = 1000 m

We have,

6 miles = 1 month

1 miles = 5280 feet

1 month = 730 hours

Now,

6 miles = 6 x 5280 feet

6 miles = 31680 feet

So,

31680 feet = 730 hours

Divide both sides by 730.

31680/730 feet = 1 hour

43.39 feet = 1 hour

Thus,

Speed is 43.39 feet per hour.

Answers

Answer:

y=-3/2x+3

Step-by-step explanation:

The slope is -3/2x because it's going down 3 and to the right 2.

And it intercepts the y-axis at 3. Thus, 3 is the y-intercept.

Answer:

y = -3/2 x +3

Step-by-step explanation:

We can use the slope intercept form

y = mx+b where m is the slope and b is the y intercept

The y intercept is 3

Now to find the slope

Pick two points on the line

( 0,3) and ( 2,0)

m = ( y2-y1)/(x2-x1)

   = ( 0-3)/(2-0)

   = -3/2

The equation of the line is

y = -3/2 x +3

The perimeter of a square courtyard is 144 m. Find the cost of cementing it at the rate of £5 per m². *

Answers

Answer:

the cost is   £ 6,480

Step-by-step explanation:

given:

The perimeter of a square courtyard is 144 m

find:

the cost of cementing it at the rate of £5 per m².

Perimeter = 4 Sides

144 = 4 S

S = 144/4

S = 36

Area = S²

A = 36²

A = 1296 m²

cost of cementing the area =   1296 m² x £5 per m²  =  £ 6,480

therefore,

the cost is   £ 6,480

Read the following passage.Wayward Penguin Released South of New Zealand by The Associated Press1 He needed a little push before speeding backward down a makeshift slide. Once in the water, he popped his head up for one last look. And then he was gone. The wayward emperor penguin known as Happy Feet was back home in Antarctic waters after an extended sojourn spent capturing hearts in New Zealand.2 Happy Feet was released into the ocean south of New Zealand on Sunday, more than two months after he came ashore on a beach nearly 2,000 miles from home and became an instant celebrity.3 Speaking from a satellite phone aboard the research vessel Tangaroa, Wellington Zoo veterinarian Lisa Argilla said Happy Feets release went remarkably smoothly given that the boat was being tossed about in 25-foot swells in the unforgiving Antarctic Ocean.4 Argilla said crew members from the boat carried the penguin inside his custom-built crate to the stern of the ship for his final send-off about 50 nautical miles north of remote Campbell Island. The crew had already cut the engines and put in place a canvas slide that they soaked with water from a hose.5 But when they opened the door of the crate, the penguin showed no interest in leaving.6 I needed to give him a little tap on his back, Argilla said.7 The penguin slipped down the slide on his stomach, bottom first, she said. He resurfaced about 6 feet from the boat, took a look up at the people aboard, and then disappeared beneath the surface.8 I was really happy to see him go, Argilla said. The best part of my job is when you get to release animals back into the wild where they are supposed to be.9 The 3-foot-tall aquatic bird was found June 20 on Peka Peka Beach, about 40 miles northwest of New Zealands capital, Wellington. It had been 44 years since an emperor penguin was last spotted in the wild in New Zealand.10 At first, conservation authorities said they would wait and let nature take its course with the penguin. But it soon became clear the birds condition was deteriorating, as he scooped up beaks full of sand and swallowed, likely mistaking it for snow, which emperor penguins eat for its moisture when in Antarctica.11 With the world watching, authorities finally took action, moving the penguin to the Wellington Zoo four days after he was discovered.12 At the zoo, the 3 1/2-year-old bird underwent numerous stomach flushing procedures to remove sand from his digestive system. He was given a makeshift home in a room that zoo staff kept filled with a bed of ice so he wouldnt overheat.13 A local television station, TV3, set up a webcam and streamed images of the bird around the clock. Soon, Happy Feet had a quarter-million followers.14 And, perhaps befitting of a bird from the Internet age, those followers will be able to keep track of him for a while longer. Happy Feet has been fitted with a GPS tracker, and his movements will be posted online. Argilla expects the tracker to fall off the next time the bird molts.15 Argilla said the final boat journey, which began last Monday and ran into terrible weather, was difficult for hershe got seasickand the crew. The one who seemed least bothered, she said, was Happy Feet, who rolled with the swells, slept standing up and took nips at the crew when they fed him fresh fish.16 Now that Happy Feet has been nursed back to health, Argilla said his chances are as good as they are for any other penguin in the wild.17 He swam away, not caring about us anymore, Argilla said.18 She paused.19 And thats a good thing, she said.What is the main idea of the article?A) New Zealanders helped a lost emperor penguin return to the Antarctic.
