Solve the following problem for the roots by completing the square

3x^2 -12x = 9

Answers

3(x^2+3) is the answer you are looking for. :)
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2.  So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}

The solutions are -0.65 and 4.65.

It snowed 4 times during October. The snowfall amounts were 0.75 inches, 1.93 inches, 4.73 inches, and 2.33 inches. What was the total snowfall for October?

Answers

9.74 inches i did this problem yesterday

The total snowfall for October was 9.74 inches. Adding the snowfall amounts of 0.75, 1.93, 4.73, and 2.33 inches resulted in this sum.

Let's break down the calculation step-by-step:

Identify the given snowfall amounts for October:

The snowfall amounts are 0.75 inches, 1.93 inches, 4.73 inches, and 2.33 inches.

Add up the snowfall amounts to find the total:

Total snowfall = 0.75 inches + 1.93 inches + 4.73 inches + 2.33 inches.

Perform the addition

Total snowfall = 9.74 inches.

The total snowfall for October was 9.74 inches. This result is obtained by adding all four individual snowfall amounts together.

So, the calculation in step-by-step form is as follows:

0.75 + 1.93 + 4.73 + 2.33 = 9.74 inches.

Noel Devine bought a new dishwasher for $320. He paid $20 down and made 10 monthly payments of $34. What actual yearly interest rate did Noel pay?
    
  A. 14.55%
  B. 29.09%
  C. 34.38%
  D. 68.75%

Answers

The yearly interest rate that Noel payed is 29.09%

Solution:

Cost price of Dishwasher bought by Noel Divine = $ 320

Down payment = $ 20

Amount given in one installment= $ 34

Total Amount paid in 10 Installment = $34 ×10=$ 340

Total amount paid for Dishwasher by Noel Divine = $340 + $ 20 = $ 360

Interest paid by noel = $ 360 - $ 320= $ 40

As the interest will be simple interest

Simple interest =[tex]\frac{Principal \times \text{time} \ \text{rate}}{100}[/tex]

40=[tex]\frac{320 \times R \times \frac{10}{12}}{100}[/tex]

R= [tex]\frac{48000}{3200}[/tex]=15% →→Option A



Patty is, right now, 3 times as her brother Terry. in 10 years, the sum of their age will be 36. how old are they right now? show your work.

Answers

Patty at year x will be 3 times the age of his brother


In 10 years (year z) the sum of their age will be 36

36-20=16
(Twenty being ten years gained for each of them)

16 is now the sum of their age in year x

The following are options for the ages they could possibly be
1-15 (1*3 does not equal 15)
2-14(2*3 does not equal 14)
3-13(3*3 does not equal 13)

6-10(6*3 does not equal 10)
7-9 (7*3 does not equal 9)
8-8(8*3 does not equal 8)


Therefore the answer would be:
Patty is 22 and his brother is 14

Patty is 12 years old, and Terry is 4 years old. After setting up an equation based on their ages now and in 10 years, we determine that Terry is 4, and since Patty is three times as old, she is 12.

The problem presented is a typical age-related algebraic question. To solve it, we can set up equations based on the information given. Let's define Patty's current age as 3T, where T represents Terry's current age. In 10 years, Patty will be 3T + 10 and Terry will be T + 10. According to the problem, the sum of their ages in 10 years will be 36. So, we can write the following equation:

3T + 10 + T + 10 = 36

Solving this equation:

Combine like terms: 4T + 20 = 36Subtract 20 from both sides of the equation: 4T = 16Divide both sides by 4 to find Terry's age: T = 4

With Terry's age being 4, Patty's current age is 3 times Terry's age, which means Patty is 3 × 4 = 12 years old. So, Patty is 12 and Terry is 4 years old right now.

Explain how the energy of a toy car is transformed as it slides down a ramp. Give evidence that the energy of the car remains the same at all points on the ramp.

Answers

At the top of a ramp, all of the energy of the car is potential: that is, it has yet to be moved but has the ability to move. As the car is sliding down the ramp, the potential energy is being transformed into kinetic energy, which reaches a maximum at halfway down the ramp. After this point, the kinetic energy begins to lessen and the potential energy begins to increase, until the car comes to a full stop, at which point kinetic energy is at zero and the potential energy is again at a maximum.

Answer:

as the car slides down the ramp it is in kinetic energy and when it is on the top of the ramp it is on potential energy we see that the energy is being transferred

The circumference of a circular field is 295.16 yards what is the radius of the field use 3.14 for pi and do not round your answer

Answers

Circumference = 2 x 3.14 x radius

295.16 = 6.28 x radius

295.16 / 6.28 = radius

47 = radius

The radius of circle is 47 yards.

What is Circumference of circle?

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle. It is typically expressed in units like cm or unit m.

The radius of the circle is considered when applying the formula to determine the circumference of the circle. Therefore, in order to calculate the circle's perimeter, we need to know the radius or diameter value.

Given:

Circumference of circle= 295.16 yards

Now,

circumference of circle= 2πr

295.16= 2 x 3.14 x r

295.16 = 6.28 x r

r = 295.16/ 6.28

r = 47 yards.

Hence, the radius of circle is 47 yards.

A painter charges an initial fee of $50 and $30 for each hour of labor. Write a linear function to determine the total cost. How much will it cost if the painter takes 4.5 hours to paint?

Answers

The initial fee of $50 is essentially the y intercept because this is the value when x = 0 (x is the number of labor-hours). So b = 50.

The slope is m = 30 because each increase of 1 hour leads to the cost bumping up by 30 dollars. In other words, slope = rise/run = (change in cost)/(change in hours) = 30/1

So we plug m = 30 and b = 50 into the y = mx+b formula to get y = 30x+50

Replace y with f(x) to get f(x) = 30x+50

The linear function for the cost is f(x) = 30x+50

Note: Some books may use other letters (instead of x and f(x)), but the idea is still the same

Once you know the cost function, you replace x with 4.5 to find the amount it will cost to have a painter work for 4.5 hours.

f(x) = 30x+50
f(4.5) = 30*4.5+50
f(4.5) = 135+50
f(4.5) = 185

It will cost 185 dollars to have the painter work for 4.5 hours

length of an edge is 12in

the area of one side is 12² or 144 in²

surface area is 6s² or 6(144) or 864 in²

A given cube with a volume of 1728 cubic inches:

Find the length of an edge:
The edge length (s) can be found using the formula for the volume of a cube: s³ = 1728. Therefore, s = 12 inches.Find the area of one side:
Each face of the cube is a square, so area of one face = s² = 12² = 144 square inches.Find the surface area:
Total surface area = 6 * (area of one face) = 6 * 144 = 864 square inches.Find the surface area in square feet:
To convert square inches to square feet, divide by 144 (since 1 square foot = 144 square inches). Therefore, surface area in square feet = 864 / 144 = 6 square feet.

What is Division?

Division is one of the four basic operations of mathematics.

On performing the operation division, a number is divided into some number of equal parts.

The number which is being divided is called the dividend, the number which divides the dividend is called divisor and the number got when division is performed is called the quotient and the remaining number which has not divided is called the remainder.

Total number of students = 40

If there is 1 group, number of students in the group = 40/1 = 40

If there are 20 students in each group, then the number of groups = 40/20 = 2.

If there are 4 groups, then number of students in each group = 40/4 = 10.

Hence there will be 40 students in the group if there is 1 group. There are 2 groups if there will be 20 students in each group. There will be 10 students in each group if there are 4 groups.
