The Students' Conjectures

Emily and Zach have two different polynomials to multiply:

Polynomial product A:
(4x2 – 4x)(x2 – 4) Polynomial product B:
(x2 + x – 2)(4x2 – 8x)
They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

Jada walks to school. The function D givers her distance from school, in meters, t minutes since she left home. Which equation tells us “Jada is 600 meters from school after 5 minutes”? A. D(600)=5 B. t(5)=600 C. t(600)=5 D. D(5)=600

Answers

Awnser:

The awnser is: D(5) = 600

Step-by-step explanation:

The equation function showing that “Jada is 600 meters from school after 5 minutes” is D(5) = 600.

What is function?

A function is defined as a relation between a set of inputs having one output each.

Given that, Jada walks to school. The function D givers her distance from school, in meters, t minutes since she left home.

According to the question,

She is 600 meters far from school after 5 minutes,

That tells that, when it is 5 min the distance left is 600 m, i.e, 5 minutes is input and 600 is output.

Hence, The equation function showing that “Jada is 600 meters from school after 5 minutes” is D(5) = 600.

37 people showed up to the party. There were 9 less men than women present. How many women were there?

Answers

Answer:

Step-by-step explanation:

tbh, i just guessed around the numbers until i got the right one xD

The number of women present in the party will be 23.

What is expression ?

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

Total persons in party = 37

Let,

Number of men = m

Number of women = w

So,

Total number of persons in party ,

m + w = 37 .....(i)

Now,

According to the question,

m = w - 9

Now

Substituting m = w - 9 in equation (i),

i.e.

w - 9 + w = 37

We get,

2w = 37 + 9

2w = 46

We get,

w = 23

So, number of women are 23.

Hence, we can say that the number of women present in the party were 23.

You are deciding between two laptops to purchase. The first laptop has an initial value
of $2000 but loses 14% of its value every year. The second laptop has an initial value
of $1200 but loses 11% of its value every year.
a. Write functions that represent the values (in dollars) of the laptops after t years.
Then graph the functions in the same coordinate plane.
b. Find the approximate monthly percent decrease in value for each laptop.
C. Which laptop should you buy if you plan on selling the laptop in 5 years? Explain
your reasoning

Answers

Step-by-step explanation:

The first laptop

Initial value- $2000Value loss - 14% every yearFunction for value- V(t) = 2000*0.86^t

The second laptop

Initial value- $1200Value loss - 11% every yearFunction- V(t) = 1200*0.89^t

Monthly percent decrease

The first laptop:

14%/12 = 1.16%

The second laptop:

11%/12 = 0.92%

The second laptop will lose less value in 5 years hence is better choice

See the graph attached

Round to the nearest tenth.
C С

Answers

Answer:

B=34.2

C=105.8

c=12.0

Step-by-step explanation:

find B using the sine rule

(sin40÷8)=(sinB÷7)

rearrange

sin B= (sin40x7)÷8

sin B=0.562

make sure to use your calculator

then press shift sin to find B

B= 34.2°

to the nearest tenth means to 1 decimal place

sum of angles in a triangle is 180

so 180-(40+34.2)=105.8°=C

use sine rule again to find c

(sin105.8÷c)=(sin40÷8)

rearrange

c= (sin 105.8x8)÷sin40

c=12.0

What is the slope of the line? question 3

Answers

Answer:

slope =1

Step-by-step explanation:

hope it help you

Answer:

Undefined.

Step-by-step explanation:

The x-coordinates of the points along the straight line are always 1.

slope = change in y-coordinate/change in x-coordinate.

Since the change in x-coordinate is 0 (1-1=0), the denominator in the above will be 0 and the fraction (i.e. the slope) would be undefined.
