help me please. i've tried this so many times, writing it out, calculator. nothing's worked

Answer:

400

Step-by-step explanation:

To find the scale factor, you need to find out how much the initial value was multiplied by to get the new value. To do that, you need to divide the new value by the initial value. Make sure the units are the same; don't divide 1000 feet by 30 inches!

[tex]\frac{new}{initial} = \frac{12000}{30}=400[/tex]

Hope this helps!

Answer:

0

Step-by-step explanation:

The slope of the line is 0 as it is parallel to x-axis.

Slope = (y2 - y1)/(x2 - x1)

= (2-2)/(4-(-2))

= 0

Answer:

Slope = 0

Step-by-step explanation:

Taking any two points.

(x1,y1) = (3,0)

(x2,y2) = (-1,0)

Now,

[tex]\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-0}{-1-3} \\\\Slope = \frac{0}{-4} \\\\Slope = 0\\\\\rule[225]{225}{2}[/tex]

ANSWER

First of all I turn the fractions back to their improper form that is to say;

6 3/4 - 4 11/12

= 27/4 - 59/12

after that I get the LCM of 12 and 4 which is 12

= (²⁷/⁴ × 12) - (⁵⁹/¹²× 12) /12

= (81 - 59) /12

= 22\12

since the answer is requested for in the simplest form the the difference in form of a mixed fration is 1 10/12 which is reduced to 1 5/6 therefore the answer is 'B'

It is neither of these. To find the inverce, interchange the variables, then solve for y:

[tex]\displaystyle x = -14y + 4 \hookrightarrow \frac{x - 4}{-14} = \frac{-14y}{-14} \\ \\ f^{-1}(x) = -\frac{x}{14} + \frac{2}{7}[/tex]

Answer:

Slope intercept is y = mx+b.

SLOPE is m

and Y-INTERCEPt, where the thing touches the y axis is b.

The line touches the y axis at -6.

The slope is 2/3

y=2/3x-6

Step-by-step explanation:

Answer:

m = -1

Step-by-step explanation:

Find the equation in slope intercept form [ y = mx + b ] for line AB. Find the slope using the formula [ y2-y1/x2-x1 ].

8-5/7-4

3/3

Find the y-intercept.

5 = 1(4) + b

5 = 4 + b

1 = b

So the equation of the line AB is y = x + 1.

The slope of a perpendicular line is the opposite reciprocal of the original line.

Answer:

April

Step-by-step explanation:

To solve, you find the maximum of the polynomial function. You can do this by either graphing or plugging in the values in a T chart.

I graphed the function, provided down below.

As you can see, the highest value in the graph is the middle most point, aka (4,1). Count down the months of the year to 4, and you'll find that April is the 4th month of the year.

Using derivative concepts, it is found that the function has a local maximum in March.

--------------------

The function is:

[tex]S(t) = t^4 - 12t^3 + 52t^2 - 96t + 64[/tex]

Which has the following derivative:

[tex]S^{\prime}(t) = 4t^3 - 36t^2 + 104t - 96[/tex]

--------------------

February is the 2nd month, thus, the derivative is:

[tex]S^{\prime}(2) = 4(2)^3 - 36(2)^2 + 104(2) - 96 = 0[/tex]

Now, we have to test a value less than 2, and one greater than two, to check if it goes from increasing to decreasing, that is, derivative goes from positive to negative.

[tex]S^{\prime}(1.5) = 4(1.5)^3 - 36(1.5)^2 + 104(1.5) - 96 = -7.5[/tex]

[tex]S^{\prime}(2.5) = 4(2.5)^3 - 36(2.5)^2 + 104(2.5) - 96 = 1.5[/tex]

From negative to positive, thus, a local minimum in February.

--------------------

March is the 3rd month, thus, the derivative is:

[tex]S^{\prime}(3) = 4(3)^3 - 36(3)^2 + 104(3) - 96 = 0[/tex]

Testing before and after:

[tex]S^{\prime}(2.5) = 4(2.5)^3 - 36(2.5)^2 + 104(2.5) - 96 = 1.5[/tex]

[tex]S^{\prime}(3.5) = 4(3.5)^3 - 36(3.5)^2 + 104(3.5) - 96 = -1.5[/tex]

From positive to negative, thus, it has a local maximum in March.

The height of the window is 9-x feet.

Given that, a window is 9 ft long. It is x feet longer than it is high.

We need to find what is the height of the window.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Here, the length of the window = 9 ft

Then, the height of the window = x feet smaller than the length = 9-x feet

Therefore, the height of the window is 9-x feet.

If 20 labourers=10 days

x labourers = 25 days

10x= 25×20

[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]

Cancelling out by 10 on both sides
