4. 0.0000024
Answers
Answer:

2. 0.0024 ⇒ 2.4 × [tex]10^{-3}[/tex]
3. 75,000,000 ⇒ 7.5 × [tex]10^{7}[/tex]
4. 0.0000024 ⇒ 2.4 × [tex]10^{-6}[/tex]
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers.
A number is written in scientific as a number between 1 and 10 and multiplied by a power of 10
The form of the scientific notation is a × [tex]10^{n}[/tex], where
1 < a < 10n is an integern is positive if the decimal point moves from right to leftn is negative if the decimal point moves from left to right1. 75000
→ Place a decimal point between 7 and 5 to make the number between
1 and 10
∴ a = 7.5
→ Count the number of the digits right to the decimal point
∵ There are 4 digits right to the decimal point
∴ n = 4
∴ 75000 ⇒ 7.5 × [tex]10^{4}[/tex]
2. 0.0024
→ Move the decimal point from left to right to place it between 2 and 4 to
make the number between 1 and 10
∴ a = 2.4
→ Count the number of the digits left to the decimal point
∵ There are 3 digits left to the decimal point
∴ n = -3
∴ 0.0024 ⇒ 2.4 × [tex]10^{-3}[/tex]
3. 75,000,000
→ Place a decimal point between 7 and 5 to make the number between
1 and 10
∴ a = 7.5
→ Count the number of the digits right to the decimal point
∵ There are 7 digits right to the decimal point
∴ n = 7
∴ 75,000,000 ⇒ 7.5 × [tex]10^{7}[/tex]
4. 0.0000024
→ Move the decimal point from left to right to place it between 2 and 4 to
make the number between 1 and 10
∴ a = 2.4
→ Count the number of the digits left to the decimal point
∵ There are 6 digits left to the decimal point
∴ n = -6
∴ 0.0000024 ⇒ 2.4 × [tex]10^{-6}[/tex]

Where is the y value that equals 0 in the x value? Right in the middle of the y line, so its 2. Hope this makes sense, I’m not too good at explaining stuff lol

The graph of the equation y = 8x - 6 is a straight line.
What is slope intercept form?The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept
(0, b).
Given is an equation, y = 8x - 6
Finding the coordinates,
Put x = 0, y = -6
(0, -6)
Put y = 0
8x = 6
x = 0.75
(0.75, 0)
Plotting the graph,
Hence, we will get a straight line of the graph.

Find the 52nd term of the arithmetic sequence 5, 9, 13
Answers
Answer:
209
Step-by-step explanation:
You would first create an explicit formula for the provided sequence.
The basic explicit formula for arithmetic sequences is [tex]a_{n} = d(n-1) + a_{1}[/tex], where an is the number of the term, d is the number you are adding or subtracting by, n the location of the term, and a1 is the first number.
We would then substitute the values given into the formula.
We are trying to solve the value of the 52nd term. This makes n = 52. The first number of the sequence is 5, so a1 is 5. Finally, d is 4 because we are adding 4 to each number in the sequence.
Therefore, our resulting equation would be [tex]a_{n} =4(52-1)+5[/tex], which equals 209.
Wilscy owns a toy store. The number of toy trains sold (in thousands) from 2000 through 2005 can be modeled by M(x) = −0.5x3 + 2x2 − x + 9. The average cost per toy train (in dollars) can be modeled by N(x) = 0.3x + 7, where x represents the number of years since 2000. The total revenue Wilscy made by the sale of toy trains is the product of the number of toy trains sold and the average cost per toy train. Identify a polynomial P(x) that can be used to model the total revenue.

volume of a pyramid = length x width x height
3
because a square has the same length and width, length = width = side
volume of a pyramid = side x side x height
3
volume of a pyramid = side² x height
3
We know the volume of the pyramid is 120 cubic meters, and the height is 10 meters, so:
120 = side² x 10
3
multiply both sides by 3
360 = side² x 10
divide both sides by 10
36 = side²
square root both sides
6 = side
A side length of the base is 6 meters.

PLS HELP FIND ANGLE MEASUREMENTS
Answers
Answer:
From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36
So,
x = 72
y = 36
