Paul is locked out of his house. An 18-ft ladder is outside and an upstairs window is open. Paul read the safety warning on the ladder recommending it be placed six feet away from the wall. He placed the ladder according to the warning and it reached the base of the window. How high is the base of the window off the ground?

Answers

Answer:

17.0 ft

Step-by-step explanation:

Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.

So, using Pythagoras' theorem,

L² = h² + d²

So, h = √(L² - d²)

Substituting the values of L = 18 ft and d = 6 ft, we have

h = √((18 ft)² - (6 ft)²)

= √(324 ft² - 36 ft²)

= √288 ft²

= 16.97 ft

≅ 17.0 ft

The local ice cream shop surveyed the customers to see which flavor of ice cream is most popular 125 people choose chocolate as their favorite which represents 25% of the customers surveyed how many total customers were surveyed A.425 B.20 C.500 D.32

Answers

Answer:

500

Step-by-step explanation:

Let there were a total of x number of customers.

As 125customers choose chocolate flavor as their favorite which is 25% of the total customers surveyed, so

25% of x = 125

0.25x=125

x=125/0.25=500

Therefore, the total number of customers surveyed is 500.

Write a rational function with an x-intercept at (-9,0), a vertical asymptote at x=3, and a hole located at (1,-5). Then, identify the horizontal asymptote.

Answers

Answer:

The rational function is [tex]f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}[/tex]

The horizontal asymptote occur at y = 1

Step-by-step explanation:

Given that the function has an x-intercept at (-9, 0), we have;

(x + 9) is a factor of the function

Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)

With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5

The general form of the function can be presented as follows;

f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)

Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1

The horizontal asymptote occur at y = 1

1. Calculate the value of x in the following diagram. 53 - Y IN Q 5x 18​

Answers

Answer:

x = 7

Step-by-step explanation:

QY = 5x

YZ = 18

QZ = 53

Thus:

QY + YZ = QZ (segment addition postulate)

5x + 18 = 53

5x = 53 - 18 (subtraction property of equality)

5x = 35

Divide both sides by 5

Jane deposits coins into her piggy bank each day. On the first of the month, Jane deposits 11 coins. Each day after that she deposit 7 more coins. What is the equation that defines how many coins she deposits after the nth day?

Answers

Answer:

11 + 7n

Step-by-step explanation:

Here, we want to write an equation that represents the the number of coins deposited after the nth day

Mathematically,

there are 11 coins

We now proceed to add;

7 * n = 7n to what we have

So finally to get the number of coins , we add up

That will be:

11 + 7n

The coordinates of point P are (1, -1)

Step-by-step explanation:

If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)

If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)

→ Assume that the coordinates of point P are (x, y)

∵ The coordinates of point P are (x, y)

∵ The rule of the reflection is R y-axis (P)

∴ Its image = (-x, y)

∵ The image = (-1, -1)

→ Equate the two images

(-x, y) = (-1, -1)

∴ -x = -1

→ Divide both sides by -1

x = 1

y = -1

The coordinates of point P are (1, -1)

The linear equation that represents the value shown below is [tex]\mathbf{y=4x+6}[/tex]

2 l 14

3 l 18

The equation will be of form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding slope

Using points (0,6) and (1,10) we can find slope by formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{10-6}{1-0}\\ Slope=\frac{4}{1}\\Slope=4[/tex]

So, we get slope m = 4

Now finding y-intercept

When x=0, the value of y is y-intercept

So, y-intercept b = 6

So, the equation having slope m= 4 and y-intercept b=6

[tex]y=mx+b\\y=4x+6[/tex]

So, The linear equation that represents the value shown below is [tex]\mathbf{y=4x+6}[/tex]

Option D is correct option.
