The quadratic function which has zeros −3 and 5 and contains the point (4, 14) is 2x²+4x+30 and the vertex points are (-1,28).

A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.

The standard form of the quadratic equation is,

ax²+bx+c=0

Here,(a,b, c) is the real numbers and (x) is the variable.

A quadratic function has zeros −3 and 5 and contains the point (4, 14). The factored form of quadratic equation is,

f(x)=a(x-z₁)(x-z₂)

Here, z₁ and z₂ are the zeros. Thus,

f(x)=a(x-z₁)(x-z₂)

f(x)=a(x-(-3))(x-5)

f(x)=a(x+3)(x-5)

This equation contains the point (4,14). Thus,

14=a(4+3)(4-5)

14=a(7)(-1)

a=14/-7

a=-2

Put the value in above equation and solve it further:

f(x)=-2(x+3)(x-5)

f(x)=-2(x²-5x+3x-15)

f(x)=-2x²-4x-30

Change the sign,

f(x)=2x²+4x+30

The equation of the quadratic function in standard form is,

f(x)=2(x+1)²+28

Thus, the vertex point are -1 and 28. Similarly, the section equation which contains the point (1, −48) can be solved.

Hence, the quadratic function which has zeros −3 and 5 and contains the point (4, 14) is 2x²+4x+30 and the vertex points are (-1,28).

The function will be a (linear function) linear equation in two variable and the equation of the function is y = 87x  - 783

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have given data:

Game(x):              13      14     15      16       17     18

Attendance(y):    348   435  552  609   696  783

If plot these points on a coordinate plane, we will see these points will align in a straight line.

We know we can find a line equation with two points:

(13, 348) and (14, 435)

[tex]\rm (y - 435) = \dfrac{435-348}{14-13}(x-14)[/tex]

y - 435 =87(x-14)

y = 87x  - 783

Thus, the function will be a (linear function) linear equation in two variable and the equation of the function is y = 87x  - 783

The quantity of the liquid in Richard's tank after 20 minutes will be 120 gallons and in Jason's tank will be 240 gallons.

A gallon is a British unit which is used for the measurement of liquids that is equal to eight pints. In Britain, it is equal to about 4.546 litres. In America, it is equal to about 3.785 litres.

It is given in the question that:-

Richard fills his pool at a rate of 6 gallons per minute.

Jason's pool already contains 200 gallons, and he fills it at a rate of 2 gallons per minute.

After 20 minutes the amount of liquid in the tank will be:-

For Richard = 6 gallons per minute. x  20  minutes= 120 gallons

For Jason= 2 gallons per minute  x  20  =40 gallons

Jason has 200 gallons already in the tank

So it will become = 200+24=240 gallons.

Hence  quantity of the liquid in Richard's tank after 20 minutes will be 120 gallons and in Jason's tank will be 240 gallons.

If the price of the car is $22,500 in 2000. Then the value of the car in 2011 with a decay of 5% every year is $12,798.

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

A car was purchased in 2000 for $22,500.

It has depreciated at a rate of 5% per year.

Then the price of the car in 2011 will be

The decay function is modeled as

[tex]\rm A = P(1-r)^t[/tex]

Then we have

Number of logs:

1. 48

2. 14

3. 90

4. 48

5. 100

Total: 300

Step-by-step explanation:

Just multiply the height with the number of trees then divide by 6. This is in theory if the length of all the trees were conjoined, as there would most likely just be less, then 300. This is because the remainder would be that of the multiplied trees height instead of getting the remainder of wood from each tree. So in case you want to try doing that option, simply divide the height first in feet by 8, then multiply that by the number of trees to give you an accurate answer of logs.

Answer:

  see attached

  total: 300 logs

Step-by-step explanation:

When calculations are repetitive, it is convenient to let a spreadsheet do them.

Here, the number of logs per tree is found by dividing the tree height by 8 feet. The number of logs from trees that height will be found by multiplying the number of trees by the number of logs that height will give.

The total number of logs is the sum of the numbers from all the tree heights.

Answer:

m = -1/4

Step-by-step explanation:

4y + x = 8

Arrange the equation in a slope intercept form y = mx+b, where m is the slope

4y + x = 8, subtract x from both sides

    4y = -x +8, divide both sides by 4

      y = -x/4 + 8/4 , simplify

      y = -x/4 + 2, compare this to the general form y=mx+b and we see that the slope m = -1/4

Answer:

m = -1/4

Step-by-step explanation:

4y + x = 8

Arrange the equation in a slope intercept form y = mx+b, where m is the slope

4y + x = 8, subtract x from both sides

   4y = -x +8, divide both sides by 4

     y = -x/4 + 8/4 , simplify

     y = -x/4 + 2, compare this to the general form y=mx+b and we see that the slope m = -1/4
