Answer:

The length of line segment AB is 5.

Step-by-step explanation:

Envision a right triangle that has one acute vertex at (-4, 2) and the other at (0, 5).  The horizontal distance from the first to the second vertex is 0 - (-4) = 4, and the vertical distance is 5 - 2 = 3.

Then the length of the hypotenuse, according to the Pythagorean Theorem, is

d = √(4² + 3²) = 5

The length of line segment AB is 5.  Note that this is a 3-4-5 triangle, and so 3² + 4² = 5²

Answer:

\(Cost \ total= \$ 1755\)

Step-by-step explanation:

Find the total cost of a rectangular shaped carpet, given the carpets length,  width, and the cost of carpet per square foot. Using the formula for the area of a rectangle.

\(\boxed{\left\begin{array}{ccc}\text{\underline{Area of a Rectangle:}}\\\\A=l \times w\end{array}\right}\)

Where...

Given:

\(l=15 \ ft\\w=9 \ ft\\ 1 \ ft^2= \$ 13\)

Find:

\(Cost \ total = \ ?? \\)

(1) - Calculating the total area of the carpet, which is a rectangle

\(A=l \times w\\\\\Longrightarrow A=15 \ ft \times 9 \ ft\\\\\therefore \boxed{A=135 \ ft^2}\)

(2) Calculate the total cost of the carpet by multiplying the total area of the carpet by the cost of one square foot of carpet

\(Cost \ total=135 \ ft^2 \times \$ 13\\\\\therefore \boxed{\boxed{Cost \ total= \$ 1755}}\)

Thus, the total cost of the carpet is found.

If two of the three numbers are 24 and 42, then the GCF of these two numbers is 6 and the third number is possibly 48.

Factor is a number which when a number is divided will result to another number(whole). For two or more numbers, the largest common factor that they have is called the Greatest Common Factor (GCF).

To find the GCF of 24 and 42, list all the factors of both numbers.

24 : 1, 2, 3, 4, 6, 8, 12, 24

42: 1, 2, 3, 6, 7, 14, 21, 42

Common Factors: 1, 2, 3, 6

Greatest Common Factor: 6

If the third number is grater than 42 and does not change the GCF, then the third number is possibly 48.

24 : 1, 2, 3, 4, 6, 8, 12, 24

42: 1, 2, 3, 6, 7, 14, 21, 42

48 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

The interval of increase for the function f(x) = ex x8 is (0, ∞).

To determine the intervals of increase or decrease for the given function, we need to analyze the sign of the derivative.

Let's find the derivative of f(x) with respect to x:

f'(x) = (ex x8)' = ex x8 (8x7 + ex)

To determine the intervals of increase, we need to find where the derivative is positive (greater than zero).

Setting f'(x) > 0, we have:

ex x8 (8x7 + ex) > 0

The exponential term ex is always positive, so we can ignore it for determining the sign. Therefore, we have:

8x7 + ex > 0

Now, we solve for x:

8x7 > 0

Since 8 is positive, we can divide both sides by 8 without changing the inequality:

x7 > 0

The inequality x7 > 0 holds true for all positive values of x. Therefore, the interval of increase for the function is (0, ∞), which means the function increases for all positive values of x.

The function f(x) = ex x8 increases in the interval (0, ∞).

The slopes of perpendicular lines are opposite reciprocals

The true statement is that segments FG and HJ are perpendicular

The coordinates of the points are given as:

F = (3,1)

G = (5,2)

H = (2,4)

J = (1,6)

Start by calculating the slopes of FG and HJ using the following slope formula

\(m = \frac{y_2 -y_1}{x_2 -x_1}\)

So, we have:

\(FG = \frac{2 -1}{5 -3}\)

\(FG = \frac{1}{2}\)

Also, we have:

\(HJ = \frac{6 - 4}{1 - 2}\)

\(HJ = \frac{2}{-1}\)

\(HJ = -2\)

To determine the relationship, we make use of the following highlights

From the computation above, we have:

Hence, segment FG and HJ are perpendicular

To obtain an overall average of 86%, a score of 96 is required on her 4th test.

Let the required score on her fourth test = t

The required average = 86%

Initial scores : 80% + 83.5% + 84.5%

Average = ΣX/ (fx)

fx = total score obtainable = 4 × 100 = 400

ΣX = sum of scores

Average = 86%

0.86 = ((80 + 83.5 + 84.5 + t) / 400)

86 = (248 + t) / 400

400 × 0.86 = 248 + t

344 = 248 + t

344 - 248 = t

96 = t

In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

Answer:

  34 square feet

Step-by-step explanation:

The net is a useful tool for computing surface area. It often must be divided into sections whose areas must be added to give the required total.

Here, it can be convenient to divide the net into a central vertical rectangle that is 4 ft wide and (1.5 +2 +1.5 +2) = 7 ft high. Then there will be 2 "wings" that are each rectangles 2 ft by 1.5 ft.

Since the area of a rectangle is the product of its length and width, the total area using the above decomposition is ...

  A = (4 ft)(7 ft) +2(2 ft)(1.5 ft) = 28 ft² +6 ft²

  A = 34 ft²
