Suppose the circumference of a circle is 3 pi. What is the diameter?

Answers

Answer 1

Answer: this was asked already
c=pid or
c=2pir

use first one
c=3pi
3pi=c=pid
3pi=pid
divide by pi
3=d
diameter=3 units

Answer 2

Answer: $2\pi r~or~ \pi d$ so divide 3 by $/pi$

Derek advises a patient to have a scale every 4 months and a polish every 6 months. If they have a scale and polish today, how long will they wait before they can have both during the same appointment?

Answers

Answer:

12 months time

Step-by-step explanation:

To find this, we simply find the lowest common multiple of the two months

Mathematically, we have the lowest common multiple of 4 and 6 as 12

Thus, the time they would have the appointment together is the simply 12 months

Answer:

12 months

Which of the following exponential functions goes through the points (1, 12) and (2, 36)?f(x) = 4(3)−x
f(x) = 3(4)−x
f(x) = 3(4)x
f(x) = 4(3)x

Answers

Its f(x) = 4(3)^x
As (x=1, y=12), you insert 1 into the variable and its from, 4 x (3)^1 = 12. Same as (x=2, y=36), it becomes 4 x (3)^2 = 36.

Answer:

$f(x)=4(3^x)$

Step-by-step explanation:

Let's evaluate the functions for every given point, so, we can conclude which of them satisfy the conditions. But first, keep in mind the following:

$a^(-n)=(1)/(a^n)$

First function:

$f(x)=4(3^(-x) )=(4)/(3^x)$

For the point (1,12)

$f(1)=(4)/(3^1) =(4)/(3) \neq12$

This function doesn't satisfy one of the conditions.

Second function:

$f(x)=3(4^(-x) )=(3)/(4^x)$

For the point (1,12)

$f(1)=(3)/(4^1) =(3)/(4) \neq12$

This function doesn't satisfy one of the conditions.

Third function:

$f(x)=3(4^x)$

For the point (1,12)

$f(1)=3(4^1)=3*4=12$

For the point (2,36)

$f(2)=3(4^2)=3*16=48\neq36$

This function doesn't satisfy one of the conditions.

Fourth function:

$f(x)=4(3^x)$

For the point (1,12)

$f(1)=4(3^1)=4*3=12$

For the point (2,36)

$f(2)=4(3^2)=4*9=36$

This function satisfies all conditions.

Therefore, since the fourth function satisfies all conditions, we can conclude it is the function which goes through the points (1, 12) and (2, 36)

1/4 Divided By 9/10=

Answers

Answer:

$(5)/(18)$

Step-by-step explanation:

When dividing fractions, the formula is simple: Keep Flip Change (KFC)

So keep $(1)/(4)$ change your division sign to a multiplication sign, and flip $(9)/(10)$ so it becomes $(10)/(9)$ .

$(1)/(4)$ · $(10)/(9)$ = $(10)/(36)$

Then you need to reduce your fraction to simplest form.

$(5)/(18)$

5/8 or 0.27

To increase an amount by 17.5% what single multiplier would you use?

Answers

You would multiply that number by 1.175

Remember that 17.5%=17.5/100=0.175

I this case, there is a whole number that is increasing by 17.5% so we add a whole to the 17.5%

100%+17.5%=117.5% or 1.175

So if 'x' was the number, the expression would look like:

1.175x

Adding

say 100 +17.5%

117.5 would be the answer
