Given the zeros of the function f (x) = x4 + 3x3 – 28x², identify whether the zero is a bounce or
cross.

Answers

Assuming the function is

f(x) = x^4 + 3x^3-28x^2

Factorising, we get

f(x) = x^2(x+7)(x-4)

Therefore, there is a double root at x = 0 and singular roots at x = -7 and 4

double roots tend to bounce, kind of like the standard quadratic y = x^2

singular roots tend to cross, kind of like a straight line on a graph, y = mx + b

Therefore, it bounces at x = 0, and crosses at x = -7 and 4

In general, a root raised to an even power bounces, and a root raised to an odd power crosses.

Review of Unit 6 Measurement:
Michael bought 42 feet of baseboard trim to put around the edges of his workout
room. He used 39 feet 5 inches, which means he still has 2 feet 7 inches leftover for
another project or to use for a repair, if needed. True or false?
Helpful conversion fact: 1 foot = 12 inches
True
False

Answers

Answer:

True

Step-by-step explanation:

Brought - the amount used

42 feet - 39 feet 5 inches.  

  42 feet 0 inches  =     41 feet 12 inches

Solve the system of equations
−2x+3y=3
−4x+5y=1

Answers

Answer:

x= 6, y= 5

Step-by-step explanation:

-2x +3y= 3 -----(1)

-4x +5y= 1 -----(2)

(1) ×2:

-4x +6y= 6 -----(3)

(3) -(2):

-4x +6y -(-4x +5y)= 6 -1

Expand:

-4x +6y +4x -5y= 5

y= 5

Substitute y= 5 into (1):

-2x +3(5)= 3

-2x +15= 3

2x= 15 -3

2x= 12

x= 12 ÷2

x= 6

What is the surface area of a rectangular brick with a length of 12 in, a width of 8 in, and a height of 6 in?

Answers

Answer:

We can apply the formula for surface area of a rectangular prism here. i.e.

Step-by-step explanation:

A=2(l×w + h×l + h×w), where l is length, h is height and w is width.

As mentioned above, length = 12 cm, width = 8 cm and height = 6 cm.

Therefore

2(12×7+6×12+6×8)=2(84+72+48)=2(204)=408. So the surface area of the brick is 408 square centimetres.

Problema Solution

There were 155 people at the basketball game. Tickets for the game are $2.50 for students and $4 for adults. If the total money received for admission was $492.50, how many students and adults attended the game?

Answer provided by our tutors

let

s = the number of student tickets sold

a = the number of adult tickets sold

there were 155 people at the basketball game

s + a = 155

the total money received for admission was $492.50

2.50s + 4a = 492.50

by solving the system of equations

s + a = 155

2.50s + 4a = 492.50

we find

s = 85 students

a = 70 adults

Answer:

50x+20=ur mom

Step-by-step explanation:

Answer:

t = 20 + .50m

m = number of miles travelled

t = total cost

Step-by-step explanation:

t represents the total cost and m represents the number of miles travelled. Since it costs .50 per mile, you would do .50m so that you could calculate the cost based on the number of miles and since the truck at first cost 20 dollars, you would add that to the equation to. This gives you t = 20 + .50m.

Explain how to compare decimals. Use the numbers 6.75 and 6.732 to
help you explain this process.

Answers

Answer:

6.75>6.732

Step-by-step explanation:

We are given that

6.75 and 6.732

We have to compare two given decimal numbers.

First we convert like decimal number

In 6.75 there are two digits after decimal point.

In 6.732 , there are three digits after decimal point

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get

6.750

Unit place of both decimal numbers are same and tenth place of both decimal number are same.

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3

5 >3

Therefore, 6.750 is greater than 6.732

6.75>6.732
