Hi,
a) 6s² = 6 * 5² = 6 * 25 = 150
b) πr² = π * 2.5² = pi * 6.25 ≈ 19.6
Rounded to one decimal place. Notice that we don't use the equal symbol here but the approximation one.
c) a² + b ² = 3² + 4² = 9 + 16 = 25
d) πr²h = π*2.3²*5.2 = π * 27.508 ≈ 86.4
Rounded to one decimal place.
e) (4/3) π r^3 = (4/3) π *1.5^3 = π * 4.5 ≈ 14.1
Rounded to one decimal place
f) x² - 2x - 24 = (-6)² - 2(-6) - 24 = 36 + 12 - 24 = 48 - 24 = 24

Step-by-step explanation:
If you use scientific notation,
move the decimal 7 places to the right to find a whole number between 1 and 9.
then, count the number of spaces.
in this instance, since the original number was a decimal, you need to put a negative power of 10.

Which line has a slope of 1, and which has a slope of 2?
Use a ruler to help you graph a line whose slope is 5. Label this line a.
Answers
Answer:
Line "L" has the slope of 1 and line "K" has the slope of 2.
In order to graph a line with the slope of [tex]\frac{1}{3}[/tex] think of the numerator as the "rise" (how much you move up/down on the y-intercept) and the denominator as the "run" (how much you move to the side on the x-intercept)
Step-by-step explanation:
A slope of "1" is simply [tex]\frac{1}{1}[/tex] so you rise up one and move to the right once. This clearly demonstrated on line "L".
A slope of "2" is [tex]\frac{2}{1}[/tex] so you rise up two and move to the right once, as is demonstrated on line "K".
For the 2nd question, line "A" will have a slope of [tex]\frac{1}{3}[/tex] therefore it will move up once and then to the side three times. It will look like the image attached to this answer.
I hope this helped! Feel free to ask questions if needed!

Option #1, 3 and 4
Step-by-step explanation:
7x - 1 <= 7
Let's try them one by one:
1)
x <= -1
-7 - 1 = -8 is less than or equal to 7: True
There could be multiple answers, so let's do the other ones:
2)
x <= 4
28 - 1 = 27 <= 7: False
3)
x <= 1
7 - 1 = 6 <= 7: True
4)
x >= -1
-7 - 1 <= 7
-8 <= 7: True
Therefore, #1, 3, and 4 are correct.

Answer:
Parallel line, [tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]
Perpendicular line, [tex]y=4-\frac{2x}{3}[/tex]
Step-by-step explanation:
For the parallel line, In the equation y=mx+c, we are trying to find c.
We know that m=[tex]\frac{3}{2}[/tex], so
we have the equation y=[tex]\frac{3x}{2} +c[/tex]
So we substitute the points we are given (3,2) into
[tex]2=\frac{3}{2}*3+c\\Thus, c= \frac{-5}{2}[/tex]
The final equation we get is
[tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]
For the perpendicular line, we need to find the inverse of the slope.
The inverse of the slope [tex]\frac{3}{2} = -\frac{2}{3}[/tex]
So, we use this in our formula and also plug in the same coordinates we were given.
Therefore, we get:
[tex]2= -\frac{2}{3}*3+a\\a=4\\\\y=4-\frac{2x}{3}[/tex]
