Answer:
[tex]y - 5 = - 3(x - 3)[/tex]
Step-by-step explanation:
our original equation
[tex]y = \frac{1}{3} x - 7[/tex]
A perpendicular slope of a line is the negative reciprocal
So our slope would be -3
point slope form is
[tex]y - y1 = m(x - x1)[/tex]
let's substitute our given point (3, 5) and our perpendicular slope, -3
[tex]y - 5 = - 3(x - 3)[/tex]
You have been asked to build a tree house with a floor that is twice as long as it is wide. You have only a certain amount of wood you can use. Which of these strategies would you be most likely to use while planning the tree
house?
A. Work backward.
B. Draw a diagram.
C. Find a pattern.
D. Act it out.
9514 1404 393
Answer:
B. Draw a diagram.
Step-by-step explanation:
Most construction starts with a diagram.
_____
Additional comment
You may actually start by finding a pattern you like, then figuring the material required to construct the pattern, then working backward to determine the dimensions you need to use to stay within your material budget. You will probably draw a diagram at many points in the planning process.

Which number is not in scientific notation? (5 points)
11 ⋅ 1021
5.7 ⋅ 109
3.1 ⋅ 10−12
1.67 ⋅ 10−5
9514 1404 393
Answer:
(a) 11·10^21
Step-by-step explanation:
"Scientific notation" has a mantissa that has one digit to the left of the decimal point. The number 11·10^21 has two digits to the left of the decimal point, so is not in the form required by scientific notation.
11·10^21 is not in scientific notation
_____
It would be correctly written in scientific notation as as 1.1·10^22.
Answer:
A) 11 ⋅ 10^21

-3x-5y=-7
Find slope of perpendicular line
Answer:
5/3
Step-by-step explanation:
We need to rewrite the equation in slope intercept form
y =mx +b where m is the slope
-3x-5y = 7
Add 3x to each side
-5y = 3x+7
Divide by -5
y = -3/5 x -7/5
The slope of this line is -3/5
Perpendicular lines have slopes that are negative reciprocals
-1 / (-3/5)
5/3
The slope of the perpendicular line is 5/3

Answer:
24, 48
Step-by-step explanation:
1. A common multiple is a number, specifically a whole number, that is a shared multiple between 2 or more numbers.
2. Given the information above, we can see there's a list of multiples for 6 and 8. The multiples that 6 and 8 share are 24 and 48, so they're common multiples.
Therefore, the answer is 24 and 48.
Answer:
The multiples which are used in both numbers are:
24 and 48
Which equation is true when the value of "y" is 3 ? PLEASE HELP. NO LINKS! A: 2y -3 =6
B: 3y -2 =6
C: 11y +4 = 37
D: 4y +11 =37
Explanation:
If we replaced y with 3 in choice A, then we get
2y-3 = 6
2(3)-3 = 6
6-3 = 6
3 = 6
which is a false statement. So choice A's solution is not y = 3. We can cross choice A off the list. The same applies with choices B and D as well.
Choice C is the answer because,
11y+4 = 37
11(3)+4 = 37
33+4 = 37
37 = 37
which is true. This confirms choice C.

rectangular equation for the curve whose parametric equations are x = 2cosθ, y = cos2θ.
The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].
In this question, we have a set of parametric equation which must be reduced into a single rectangular equation both by algebraic and trigonometric means, that is to say:
[tex]x = f(\theta), y = g(\theta) \to y = h(x)[/tex]
If we know that [tex]x = 2\cdot \cos \theta[/tex] and [tex]y = \cos 2\theta[/tex], then the rectangular equation is:
[tex]y = \cos 2\theta[/tex]
[tex]y = \cos^{2}\theta - \sin^{2}\theta[/tex]
[tex]y = 2\cdot \cos^{2}\theta -1[/tex]
[tex]\cos \theta = \frac{x}{2}[/tex]
[tex]y = 2\cdot \left(\frac{x}{2} \right)^{2}-1[/tex]
[tex]y = \frac{x^{2}}{2} -1[/tex]
The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].

If Marie were to paint her living room alone, it would take 7 hours. Her sister Barbara could do the job in 8 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.
Answer:
[tex]\sf\longmapsto \: 3.73 hours [/tex]
Step-by-step explanation:
[tex]\sf\longmapsto \: \frac{1}{7 } + \frac{1}{8} [/tex]
[tex]\sf\longmapsto \: \frac{15}{56} [/tex]
Now, Reciprocal–
[tex]\sf\longmapsto \: \frac{56}{15} [/tex]
[tex]\sf\longmapsto \: 3.73 hours [/tex]
The time taken together Marie and his sister to paint the living room are 3.73 hours or 3 hours and 43.8 minutes.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour.
Given that,
Marie take 7 hours to paint
1 work → 7 hour
1 hour → (1/7) work
Barbara takes 8 hour
1 work → 8 hour
1 hour → (1/8) work
Let's suppose together they take x hour
1 work → x hour
1 hour → (1/x) work
Now,
1-hour work together = 1-hour work of Marie + 1-hour work of Barbara
(1/x) = (1/7) + (1/8)
(1/x) = (7 + 8)/56
x = 56/15
x = 3.73
x = 3 hour and 0.73 × 60 = 43.8 minutes.
Hence "The time taken together Marie and his sister to paint the living room is 3.73 hours or 3 hours and 43.8 minutes".
