Four friends are training for long races.

Eduardo ran 5.123 miles, Kandis ran 6.34 miles, Khaliyah ran 7.1 miles, and Moises ran 8 miles.

Khaliyah ran how much further than Eduardo?

Answers

Answer 1

Answer:

1.977

Step-by-step explanation:

line up your decimal points

 7.100

- 5.123  (borrow from 1 to make it 0 and make the 0 to the right of it a 10)

             (now borrow from the 10 to make it 9 and make the other zero a 10)

7.100

- 5.123  (now borrow from 7 to make it 6 and make the 0 to the right of it a 10)

        7   (now borrow from the 10 to make it 9 and subtract the 2)

7.100

- 5.123  (now subtract 1 from 10 and then subtract 5 from 6)

 1.977  

 

Answer 2
Khaliyah ran 1.977 miles further than Eduardo , simply take away 5.123 from 7.1 :)

What is a polynomial?

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

We have been given the polynomial function:

⇒ x³ + 2x² - 3x -6

Simplify the radical by breaking the radicand up into a product of known factors.

⇒ x³ + 2x² - 3x -6

Add and subtract the second term to the expression and factor by grouping.

⇒ x²(x + 2) - 3(x + 2)

⇒ (x + 2)(x² - 3)

⇒ (x + 2)(x +√3)(x-√3)

Therefore, the factorised form of given function f(x) is (x + 2)(x +√3)(x-√3).

Ln 40 + 2 ln 1/2 + ln x

Answers

ln(40) + 2ln(1/2) + ln(x)

First, you should take the 2 and put it back in the argument. Since it's a coefficient, when you put it back it in would be a power. That changes 2ln(1/2) to ln(1/2 ^ 2), which is ln(1/4).

ln(40) + ln(1/4) + ln(x)

Then, to add these, we just multiply the arguments, meaning we just have:

ln(40 * 1/4 * x)

Multiply and then we're done.

ln(10x)

Using logarithmic function, the condense of Ln 40 + 2 ln 1/2 + ln x is ln(10x).

What is logarithmic function?

Logarithmic function is function is an " inverse of an exponential function so that the independent variable appears logarithmic function".

According to question,

Ln 40 + 2 ln 1/2 + ln x

Properties of Logarithmic function     [tex]x ln (a) = ln(a^x)[/tex].

Using above properties we can write [tex]2 ln \frac{1}{2}[/tex] [tex]= ln(a^(\frac{1}{2})^2)[/tex] [tex]=ln(a^\frac{1}{4})[/tex].

Properties of Logarithmic function [tex]ln(a) + ln(b) = ln(ab)[/tex]

Using above properties we can write Ln 40 + 2 ln 1/2 + ln x as [tex]ln(40 . \frac{1}{4}.x)[/tex].

= [tex]ln(10x)[/tex]

Hence, Using logarithmic function, the condense of Ln 40 + 2 ln 1/2 + ln x is ln(10x).

A camera store offers a discount of 5% off the cost of photo paper. The discount is applied before tax. A customer buys photo paper that costs $13.50 before tax. Which amount is closest to the cost of the paper with the discount before tax?​

Answers

Answer:

the amount that nearest to the paper cost with the discount but before tax is $12.83

Step-by-step explanation:

The computation of the amount that nearest to the paper cost with the discount but before tax is shown below:

= Cost of a photo paper - discount

= $13.50  - 5% of $13.50

= $13.50 - $0.675

= $12.83

Hence, the amount that nearest to the paper cost with the discount but before tax is $12.83

What is an equation of the line that passes through the points (-4, 2) and
(-8, -3)?

Answers

Do change in y over change in x to find the gradient, so:

-3 - 2 -5
———— = ———— = 5/4 or 1.25
-8 - (-4) -4

Use the equation y - y1 = m(x -x1) , so:

y -2 = 5/4(x - (-4))

y -2 = 5/4(x+4)

y -2= (5/4)x + 5 +5

y = (5/4)x + 12

A car that has a wheel radius of 1.5 feet travels 30 miles in 45 minutes. How fast are the wheels spinning? Give your answer in revolutions per minute.​

Answers

Answer:

373.43 rev/min

Step-by-step explanation:

Given data

r= 1.5ft

v=30 miles per 45 minutes

convert miles per hour to ft per minute

=30miles/45 minutes* 5280ft/1 mile

=158400/45 minutes

v=3520 feet per minute

so

v=wr

substitute

3520= w*1.5

w= 3520/1.5

w=2346.66 rad/min

Convert to rev/min

=2346.66 rad/min*1rev/2*π rad

=2346.66/2*3.142

=2346.66/6.284

=373.43 rev/min

Hence the answer is 373.43 rev/min
