Mathematics
1 answer:
Mashutka [201]3 years ago
7 0

Answer:

3

Step-by-step explanation:

3^10= 3^7(x^3)

59049= 2187(x^3)

59049/2187= x^3

27=x^3

Do the square root of 3 to both sides and you end up with x=3.

Hope this helped :)

Ax + c = R (solve for x)
sp2606 [1]
Ax + c = R     (subtract c from each side)

Ax + c - c = R - c

Ax = R - c     (divide A from each side)

Ax/A = (R-c)/A

x = \frac{R-c}{A}  <-answer

The ages (in years) of the 6 employees at a particular computer store are 44, 46, 40, 34, 29, 41
son4ous [18]
step 1
<span>compute the average: add the values and divide by 6
Average =(44+ 46+40+34+29+41)/6=39

step 2
</span><span>Compute the deviations from the average
dev: (44-39)=5,
</span>dev: (46-39)=7
dev: (40-39)=1
dev: (34-39)=-5
dev: (29-39)=-10
dev: (41-39)=2

step 3
<span>Square the deviations and add
sum (dev^2): 5^2+7^2+1</span>^2+-5^2+-10^2+2^2
sum (dev^2): 25+49+1+25+100+4-----> 204

step 4
<span>Divide step #3 by the sample size=6
(typically you divide by sample size-1 to get the sample standard deviation,
 but you are assuming the 6 values are the population,
so
no need to subtract 1, from the sample size.
This result is the variance
Variance =204/6=34

step 5
</span><span>Standard deviation = sqrt(variance)
standard deviation= </span>√<span>(34)------> 5.83

the answer is
5.83</span>

Fill in the table for the exponential function given f(x)=3(2)^n
mina [271]

Answer:

A = 3/2

B = 3

C = 6

D = 12

Step-by-step explanation:

Simply plug it in. When you have a negative exponent, you basically switch the sign of the exponent and put a one over the number itself.

  • So we have 2^-1. This is the same as 3(\frac{1}{2^1}) =3( \frac{1}{2}) = \frac{3}{2} = a
  • Now do 3(2^0) = 3 = b
  • Then do 3(2^1) = 6 = c
  • Finally do 3(2^2) = 12 = d
