How many significant figures does the following number have: 0. 0 0 2 0 4 0

Answers

Answer 1

Answer:

Four significant figures

Step-by-step explanation:

Rules of significant figure:

1. Zeros before any non-zero digit are considered to be NON-significant.

2. Any zeros between any non-zero digits are SIGNIFICANT

0.505

Here, there are three significant digits: 505

3. Any zeros that are to the right of the decimal point and a non-zero number are SIGNIFICANT.

4.0000

4. All non - zero digit are significant

Therefore,

0.002040 has four significant figures

2040

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form. (2,8), and (8,2)

Answers

Answer:

[tex]y=-x+10[/tex]

Step-by-step explanation:

Hi there!

Slope intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Find the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (2,8),and (8,2)

​[tex]m=\frac{2-8}{8-2}\\m=\frac{-6}{6}\\m=-1[/tex]

Therefore, the slope of the line is -1. Plug this into  [tex]y=mx+b[/tex]:

[tex]y=-x+b[/tex]

2) Find the y-intercept (b)

[tex]y=-x+b[/tex]

Plug in a given point and solve for b

[tex]8=-2+b[/tex]

Add 2 to both sides

[tex]8+2=-2+b+2\\10=b[/tex]

Therefore, the y-intercept is 10. Plug this back into [tex]y=-x+b[/tex]:

[tex]y=-x+10[/tex]

write the product in standard form: (3y-5)(3y+5)

Answers

Answer:

9y^2 - 25

Step-by-step explanation:

This is the product of the sum and difference of two squares:

(a - b)(a + b) = a^2 - b^2 (a formula well worth memorizing)

Therefore, (3y - 5)(3y + 5) = 9y^2 - 25, which is in standard form.

The kids are racing around a circle on the playground with a radius of 12 feet. If they ran around it 5 times, how far did they run round to the nearest foot?

Answers

Answer:

377 feet

Step-by-step explanation:

Find the circumference on the circle, using the formula C = 2[tex]\pi[/tex]r

Plug in 12 as r, the radius, then solve:

C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex](12)

C = 24[tex]\pi[/tex]

Multiply this by 5, since the kids ran around it 5 times:

24[tex]\pi[/tex](5)

= 120[tex]\pi[/tex]

To the nearest foot, this is 377.

So, the kids ran round 377 feet

For a given geometric sequence, the 9th term, a9, is equal to 43/256 and the 14th term, a14, is equal to 172. Find the value of the 18 term

Answers

Answer:

[tex]18th=44032[/tex]

Step-by-step explanation:

From the question we are told that:

9th term [tex]a9=\frac{43}{256}[/tex]

14th term [tex]a14=172[/tex]

Generally the equation for Geometric sequence is mathematically given by

 [tex]a_n=a_1r^{n-1}[/tex]

For 9th term

 [tex]\frac{43}{256}=a_1r^{8}[/tex]

For 14th term

 [tex]172=a_1r^{13} \\a_1=\frac{172}{r^13}[/tex]

Substitute in 9th term

 [tex]\frac{43}{256}=\frac{172}{r^13}*r^{8}[/tex]

 [tex]\frac{43}{256*172}=r^{-5}[/tex]

 [tex]r=^5sqrt{\frac{44032}{43}}[/tex]

 [tex]r=4[/tex]

Therefore First term a is given as

 [tex]a_1=\frac{172}{4^13}[/tex]

 [tex]a_1=2.563*10^{-6}[/tex]

Generally the equation for the 18th term is mathematically given by

 [tex]18th=a_1r^{17}[/tex]

 [tex]18th=2.563*10^{-6}*4^{17}[/tex]

 [tex]18th=44032[/tex]

1 A car uses 20 litres of petrol to travel 160 km.
How much petrol does the car use to travel 400 km?​

Answers

50 litres of petrol is the answer

Answer:

50 litres

Step-by-step explanation:

If you think of it as a ratio, there are 20 litres to every 160 km. There are __ litres to every 400 km. To get to 400, 160 is multiplied by 2.5

So multiply 20 by the same number and you get the number of litres for 400 km.

20 * 2.5 = 50

Answer:

[tex] \huge{x = \frac{7}{2} }[/tex]

Step-by-step explanation:

5(x - 9) + 3(x + 4) = 2(x - 6)

First expand the terms in the bracket

That's

5x - 45 + 3x + 12 = 2x - 12

Simplify

8x - 33 = 2x - 12

8x - 2x = 33 - 12

6x = 21

Divide both sides by 6

[tex] \frac{6x}{6} = \frac{21}{6} \\ x = \frac{21}{6} [/tex]

Simplify

We have the final answer as

[tex]x = \frac{7}{2} \\ [/tex]

So, for the slope, you’ll have to do rise over run (or change in y over change in x) so it’ll be 2/1 so your slope will be 2

And the y intercept can be found if you compare the equation give to y=mx+b, this is because b is the y-intercept value which is those equation will be 2.

The distance s s that an object falls varies directly with the square of time, t t, of the fall. If an object falls 16 16 feet in one second, how long for it to fall 256 256 feet

Answers

Answer:

It will take 16 seconds to fall 256 feet.

Step-by-step explanation:

The distance s that an object falls varies directly with the square of time t of the fall i.e.

[tex]s=kt[/tex]

Where

k is the constant of proportionality

An object falls 16 feet in one second, it means,

16 feet = 1 second

1 feet = (1/16) seconds

To fall 256 feet,

[tex]t=\dfrac{256}{16}\\\\t=16\ s[/tex]

So, it will take 16 seconds to fall 256 feet.

Both 4x^2 and 64 are perfect squares

Step-by-step explanation:

If you are looking for the difference of squares, the two terms both have to be squares. We know that 64 is a square because it is 8 x 8. Also, we can say 4x^2 is a square because it can also be written as (2x)^2. We are basically looking for an option that tells us that they are square. This is option 1.

The second option is invalid because being an even number does not mean the number is a square.

The third option does not help the case much either. Just because there is a common perfect square factor, does not mean the numbers themselves are perfects squares.
