2x^3+6x^2+2x+6

= 2(x^3 + 3x^2 + x + 3)

= 2[x^2 (x + 3) + (x + 3)]

= 2(x^2 + 1)(x + 3)

hope it helps

F(-3) = 2*-27 + 6*9 + 2*-3 + 6 = 0

so x + 3 is a factor

dividing the function by x + 3 gives the quotient

2x^2 + 2 = 2 (x^2 + 1)

So the factors are 2(x^2 + 1)(x + 3) Answer

Question

A gumball machine contains 23 green gumballs, 52 red gumballs, 34343434 blue gumballs, 61 yellow gumballs, and 30 pink gumballs. What percentage of the gumballs are red?

Solution 1

So percent means parts out of 100

x%=x/100

so we jsut have to find

(red)/(total)

add 23+52+34343434+61+30=34343600

red=52

52/34343600

divide out

0.0000015141103/1

multiply by 100/100

0.00015141103/100=0.00015%

make bottom number 100

26/100=26%

answer is 26%

x%=x/100

so we jsut have to find

(red)/(total)

add 23+52+34343434+61+30=34343600

red=52

52/34343600

divide out

0.0000015141103/1

multiply by 100/100

0.00015141103/100=0.00015%

make bottom number 100

26/100=26%

answer is 26%

Question

. Convert 5π/3 to degrees

Solution 1

radians is equal to 180 degrees.

Convert to 180 to get the following fraction:

Multiply 5 and 180 together to get the following fraction:

Simplify the fraction.

= 300

The answer is**300 degrees.**

Convert to 180 to get the following fraction:

Multiply 5 and 180 together to get the following fraction:

Simplify the fraction.

= 300

The answer is

Solution 2

Π radians = 180 degrees

so 5π / 3 radians = 180 / π * 5 π / 3 = 900 / 3 = 300 degrees Answer

so 5π / 3 radians = 180 / π * 5 π / 3 = 900 / 3 = 300 degrees Answer

Question

2. The robot was initially placed at position (6,9), and at = 2 seconds, its position is (10,15). a. How far did the robot travel in 2 seconds?
b. What is the speed of the robot?
Could you work it out

Solution 1

what's its speed? well, it traveled √(52) in 2 seconds, so is simply √(52)/2, which is about 3.6 units per second.

Question

Challenger Elementary School has 8 0 0 800800 students. Every Wednesday, 1 2 % 12%12, percent of the students stay after school for Chess Club. How many students attend Chess Club on Wednesdays?

Solution 1

You need to calculate 12% of 800.

To find a percent of a number, multiply the percent by the number.

Change the percent into a decimal by dividing the percent by 100 (move the decimal point of the percent two places to the left.)

12% of 800 =

= 12% * 800

= 0.12 * 800

= 96

Answer: 96 students

Question

If BC is tangent to circle O and OB is a radius, what kind of triangle is OBC?

Solution 1

Hi there!

Triangle OBC is a**right triangle**. This is because where the radius and the tangent meet creates a right angle. A right angle is created due to the theorem that states that a radius is perpendicular to its tangent.

Question

What is the range of the data set 2 | 1, 3, 8, 8
5 | 2, 4, 6, 6, 7
6 | 0, 1, 1
Key: 6| 0 means 60 please help i do not get this plz solve

Solution 1

The range is the difference between the highest and lowest values.

The highest value is 61.

The lowest value is 21.

range = highest value - lowest value = 61 - 21 = 40

The highest value is 61.

The lowest value is 21.

range = highest value - lowest value = 61 - 21 = 40
