4x−3y=18 Step 2 of 2 : Determine the missing coordinate in the ordered pair (?,12) so that it will satisfy the given equation.

Answers

Answer 1

Answer:

13.5

Step-by-step explanation:

The point with the missing coordinate is (?, 12), so the value of  y  is 12.  Plug 12 into the equation in the place of  y.

4x - 3(12) = 18

4x - 36 = 18

4x = 54

x = 54/4 = 13.5

Answer 2

Answer:39/8

Step-by-step explanation:

4x-3(1/2)=18

4x-3/2=18

4x=18+3/2

4x=39/2

x=39/8

b.What is the range of the data?

c.What is the mean number of minutes that she practiced?

Answers

Answer:

a. 20

b. 32

c. 20.6

Step-by-step explanation:

Median is the middle number- so put the numbers in order from least to greatest, and find the middle number

8, 10, 10, 15, 15, 20, 20, 20, 25, 25, 25, 35, 40

Median is 20

the range is the difference between the largest and the smallest value- 40-8 is 32

Mean is the average- add all the values and divide by the total number of values (13)

268 minutes divided by 13 days

mean is about 20.6 minutes

What are the zeros of this function (g)(x)=3x^2-33x-180

Answers

3x²-33x-180=3(x²-11x-60)=3(x-15)(x+4)

The roots are x-15=0, x=15 and x+4=0, x=-4

3x² - 33x - 180 = 0

3(x² - 11x - 60) = 0

3(x - 15)(x + 4) = 0
(x - 15)(x + 4) = 0

x - 15 = 0 or x + 4 = 0

x = 15 or x = -4

What is the general form of a quadratic function?

In Mathematics and Geometry, the general form of a quadratic function can be modeled and represented by using the following quadratic equation;

y = ax² + bx + c

Where:

a and b represents the coefficients of the first and second term in the quadratic function.c represents the constant term.

Since the leading coefficient (value of a) in the given quadratic function  f(x) = ax² + bx + c is positive 1/2, we can logically deduce that the parabola would open upward. Also, the value of the quadratic function f(x) would be minimum.

PLSS HELP

Answer:

because the formula for the triangle is 1/2×b×h

and the formula for the rectangle nos l×w and then add those.

Answer:

A = 60yd

Step-by-step explanation:

First "separate" the rectangle and the triangle in your head.

Now calculate the area of the rectangle and then the area of the triangle.

Rectangle: 6*8 = 48

Triangle: (6*4)/2 = 24/2 = 12

Now we add them together:

48 + 12 = 60yd

You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path.
a. Write a rule for the sequence using centimeters. The initial height is given by the is term n = 1.
b. What height will the ball be at the top of the sixth path?

1) A(n) = 1.5 • (0.74)^x-1; 0.33cm
2)A(n) = 0.74 • (1.5)^x-1; 5.62cm
3) A(n) = 150•(0.74)^x-1; 33.29cm
4) A(n) = 150 • (74) ^x-1; 332,850,993,600cm

Answers

Answer:

[tex](a)\ A(n) = 150 * (0.74)^{n-1[/tex]

[tex](b)\ A(6) = 33.29cm[/tex]

Step-by-step explanation:

Given

[tex]a = 1.5[/tex] --- initial

[tex]b = 74\%[/tex] --- rate

Solving (a): The rule of the sequence

First convert [tex]a = 1.5[/tex] to centimeters

[tex]a = 1.5 * 100[/tex]

[tex]a = 150[/tex]

The equation is then calculated using the following geometric progression formula

[tex]A(n) = ab^{n-1}[/tex]

This gives:

[tex]A(n) = 150 * (74\%)^{n-1}[/tex]

Express percentage as decimal

[tex]A(n) = 150 * (0.74)^{n-1[/tex]

Solving (b): The height on the 6th path

This implies that:

[tex]n = 6[/tex]

So, we have:

[tex]A(6) = 150 * (0.74)^{6-1[/tex]

[tex]A(6) = 150 * (0.74)^5[/tex]

[tex]A(6) = 150 * 0.222[/tex]

[tex]A(6) = 33.3cm[/tex]
