A ladder rests against the top of a wall. The head of a person 6 feet tall just touches the ladder the person is 9' from the wall and 6' from the foot of the ladder. find the height of the wall
Answer:
15 ft
Step-by-step explanation:
Let the height of the wall be represented bad x
Applying the theorem of similarity, we would have the following equation:
[tex] \frac{x}{6} = \frac{9 + 6}{6} [/tex]
[tex] \frac{x}{6} = \frac{15}{6} [/tex]
[tex] \frac{x}{6} = \frac{5}{2} [/tex]
Cross multiply
[tex] x*2 = 5*6 [/tex]
2x = 30
Divide both sides by 2
x = 15
Thus, the height of the wall = 15 ft

Answer: 7 1/2 minutes
Answer:
7.5 mins.
Step-by-step explanation:
We know the unit rate is 1.5 mins for 1 km. So we can just multiply both numbers by 5.
1.5/1 = 7.5/5
It takes a shark 7.5 (7 1/2) minutes to swim 5 km.
The American Association of Individual Investors (AAII) polls it subscribers on a weekly basis to determine the number who are bullish, bearish, or neutral on the short term prospects for the stock market. Their findings for the week ending March 2, 2014, are as follows: Bullish 409 Neutral 299 Bearish 291 Develop a point estimate of the following population parameters. The proportion of all AAII subscribers who are bullish on the stock market.
Answer: The proportion of all AAII subscribers who are bullish on the stock market is 0.4094
Step-by-step explanation:
Given the data in the question;
The total number of American Association of Individual Investors in stock market are;
409 + 299 + 291 = 999
The proportion of all AAII subscribers who are bullish on the stock market will be:
Market = 409 / 999
= 0.4094
Therefore, The proportion of all AAII subscribers who are bullish on the stock market is 0.4094
if g(x)= 1- 3/4x find the value of g(-12)
Answer:
17/16
Step-by-step explanation:
g(-12) = 1+3/48 = 1+1/16
The function of g(x)= 1- 3/4x the value of g(-12) is 1.0625.
Given:
g(x)= 1- 3/4x
g(-12) = 1-3/4x(-12)
g(-12) = 1-3/-48
g(-12) =1.0625
What is function?The function X to Y assigns exactly one element of Y to each element of X . The set X is called the range of the function and the set Y is called the code interval of the function.
A function is an equation that has only one answer for y for each x. A function specifies exactly one output for each input of a given type. It is common to call either f(x) or g(x) instead of the y function. f(2) means that we should find the value of our function when x is 2.

9.) Is the graph below line your nonlinear?
Answer:
Linear.
Step-by-step explanation:
A linear graph is any straight-line graph. That's a straight line.
Answer:
No
Step-by-step explanation:
This graph is not a non-linear line, in fact, it's a linear line. A non-linear line is a line that is not straight, a line that is curved. And as you can see in this graph, the line is straight which makes it a linear line.

A line passes through the points (-1, -8) and (3, 12). Compute the slope of
the line. Show your steps. *
Your answer
This is a required question
A line passes through the points (-1, -8) and (3, 12). Write the equation for
the line that passes through these points in the form y=mx + b. (Hint: you
already computed m in the previous problem.) *
Answer:
y = 5x - 3
Step-by-step explanation:
The Slope of a Line
Suppose it's given a line that passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The equation of the line in slope-intercept form is:
y=mx+b
Where:
m = slope
b = y-intercept.
We are given the points (-1,-8) and (3,12). Compute the slope:
[tex]\displaystyle m=\frac{12+8}{3+1}=\frac{20}{4}=5[/tex]
The equation of the line now has one known value:
y = 5x + b
Let's use the point (3,12) to find the value of b:
12 = 5(3) + b = 15 + b
Solving for b:
b = 12 - 15 = -3
The required equation of the line is:
y = 5x - 3

Passes through (-4,-5) Slope = -314
Please Helppppp!!!!!!!!!!!!
Answer:
[tex]y=-314x-1261[/tex]
Step-by-step explanation:
When we are writing an equation we have to put it in slope-intercept-form [tex]y=mx+b[/tex]. We already know the slope it's -314, we replace m with the slope. Now we have to find b which is the y-intercept. So what we have to do is plug in the ordered pair into the equation. -4 for x and -5 for y.
[tex]y=mx+b\\-5=-314(-4)+b[/tex]
Now we solve
[tex]-5=-314(-4)+b\\-5= 1256+b\\b=-1261[/tex]
So now that we know everything we need we plug in and....
[tex]y=mx+b\\y=-314x-1261[/tex]
we've got our equation!
Answer:
The line slants upward, so the slope is positive.

Therefore:
409=449
Answer:
4 4/9
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Hello!
[tex]\large\boxed{x = 17}[/tex]
[tex]\sqrt{x -1} + 5 = 9[/tex]
Begin by subtracting 5 from both sides:
[tex]\sqrt{x -1} = 9 - 5\\\\\sqrt{x -1} = 4[/tex]
Square both sides to get rid of the radical:
[tex]x - 1 = 16[/tex]
Add 1 to both sides to completely isolate for x:

Find the slope intercept equation of the line
Answer:
Step-by-step explanation:
slope-intercept formula looks like [y=mx + b]
use two points to find the slope.. or look at the graph carefully to see it there are easy points to count from.... hmmm
yes.. this is very easy to just count.. no math needed :P
the slope is posive. b/c the graph looks like you are walking up hill.. and it's rise over run is 2/1 .. so the slope is 2
then by looking at the graph I can also see that when x = 0 the line pass exactly thur +1.. sooo that tells me all I need to know for the sloop-intercept formula
y= 2x+1 :) see?
Determine whether the points on the line rise, fall, are horizontal, or vertical.
(2, -4) and (4, -1)
Answer:
The points rise.
Step-by-step explanation:
Points on a line have the following format: (x,y)
They rise if: As x increases, so does y.
They fall if: As x increases, y decreases.
They are horizontal if: As x increases, y remains constant.
They are vertical if: x is constant as y changes.
In this question:
Points (2,-4) and (4,-1).
x increases from 2 to 4.
y increases from -4 to -1.
That is, both increase, so the points rise.
Determine the input value for which the statement
f(x) = g(x) is true.
From the graph, the input value is approximately .
f(x) = 3 and g(x) = x – 2
3 = x – 2
5 = x
The x-value at which the two functions’ values are equal is .
Answer:
The x-value at which the two functions' values are equal is 5.
Step-by-step explanation:
Let [tex]f(x) = 3[/tex] and [tex]g(x) = x-2[/tex], if [tex]f(x) = g(x)[/tex], then:
[tex]x - 2 = 3[/tex]
[tex]x = 3+2[/tex]
[tex]x = 5[/tex]
The x-value at which the two functions' values are equal is 5.
