Answer:

4x^3-6x^2-6x+9

Step-by-step explanation:

I would write out the solutions as expressions and expand them:

(x-2)(x-1/2)(x-3/2)

(x^2-1/2x-2x+1)(x-3/2)

(x^2-5/2x+1)(x-3/2)

x^3-(3/2)x^2-(5/2)x+15/4+x-3/2

x^3-(3/2)x^2-(3/2)x+9/4

Next, since the leading coefficient has to be 4x^3, I could just multiply the entire expression by 4:

4x^3-(12/2)x^2-(12/2)x+36/4

4x^3-6x^2-6x+9

Hopefully, this was helpful! Comment below if you would like me to explain further!

By using the quadratic regression feature of a graphing calculator a quadratic model would be [tex]y = 0.06 x^2 + 0.31 x + 4[/tex]

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Speed (mph)           Stopping distance (ft)

10                                12.5

20                               36.0

30                               69.5

40                               114.0

50                               169.5

60                               249.0

70                               325.5

Use the quadratic regression feature of a graphing calculator to find a quadratic model.

From the above data, we get

[tex]y = 0.06 x^2 + 0.31 x + 4[/tex]

Answer:

v = 141.76 m/s

Step-by-step explanation:

Given that,

The ball reaches the ground with a velocity of 4.43h m/sec.

We need to find the velocity of the ball at a height of 32 m.

Since, v = 4.43h

Put h = 32 m in the above expression.

v = 4.43(32)

v = 141.76 m/s

So, the velocity of the ball is equal to 141.76 m/s.

Answer:

A) Number of mango trees

B) Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C)number of mango trees = 40% × 2230

D) 892 mango trees

Step-by-step explanation:

A) What is asked is the number of mango trees

B) We are given;

Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C) Number sentence is defined as when we use an equation or inequality to describe an expression using numbers and signs.

We have percentage of coconut trees = 60%.

Thus, percentage of mango trees = 100% - 60% = 40%

In this case, the number sentence is; number of mango trees = 40% × 2230

D) number of mango trees = 40% × 2230 = 892

Answer: 7 miles

Step-by-step explanation:

The points for Tom's house (4, 2) and the store (-3, 2) are on the same level; they are on the same horizontal line 2 units above the x-axis.

The distance between the points is therefor the difference between the x coordinates.

4 - (-3) = 7

You can also just count the spaces between the points!

Answer:

9/4 = 2 1/4

Step-by-step explanation:

According to the information shown in this word problem, you need 3/4 of a cup of yogurt for one smoothie. In order to find out how many cups of yogurt you would need for three smoothies, you would need to multiply 3/4 by three.

Like this,

3/4 x 3 = 9/4

9/4 = 2 1/4 (simplified)

Answer:

27

Step-by-step explanation:

An isosceles triangle has two identical angles.

The three angles need to add up to 180 degrees.

If one angle is 100 then the other two angles added together need to equal 180-100 =‘80 degrees.

Since two angles need to be the same the other angles are 80 / 2 = 40 degrees each.

The answer is 40

Answer:

A. first answer on the left.

Step-by-step explanation:

If one of the angles is 100 then if the triangle is isosceles then the two remaining angles have to be either 100 and - 20 (which is impossible because at this level of math there is no such thing as an angle with a measure of - 20).

The minus 20 comes from every triangle having 180 degrees. 100 + 100 adds to 200, which means the third angle has to be the impossible measure of - 20.

The other possibility is that the given angle of 100 is the top angle and that leaves 80 degrees for the two isosceles angles.

2x = 80

x = 80/2

x = 40

The only possible answer is 40 - 40 - 100

Step-by-step explanation:

y=1/3x-2 is the slope form of -5x+15y=-30.

a line is an infinitely long object with no width, depth, or curvature.

The given equation is -5x+15y=-30

minus five x plus fifteen y equal to minus thirty.

The standard form or slope form of a line is

y=mx+c

Where m is the slope and c is y intercept.

We need to convert  -5x+15y=-30 to standard form or slope intercept form of a line.

-5x+15y=-30

15y=-30+5x

15y=5x-30

Divide both sides by 15

y=5/15 x-30/15

y=1/3x-2

Hence y=1/3x-2 is the slope form of -5x+15y=-30.
