What is the unit rate of 1.49 for 10
kap26 [50]

If you mean it costs $1.49 to buy 10 items, then the unit rate is $0.15 or 15 cents

This is because you divide 1.49 over 10 like so: 1.49/10 = 0.149, then round this to the nearest penny to get 0.15

0.15 dollars = 15 cents

so basically whatever this item is, it costs 15 cents per item

46.The function f graphed above is the function f(x) = log2(x) + 2 for x > 0. Find a formula for the inverse of this function
pantera1 [17]

Answer:

The inverse for log₂(x) + 2  is - log₂x + 2.

Step-by-step explanation:

Given that

f(x) = log₂(x) + 2

Now to find the inverse of any function we put we replace x by 1/x.

f(x) = log₂(x) + 2

f(1/x) =g(x)= log₂(1/x) + 2

As we know that

log₂(a/b) = log₂a - log₂b

g(x) = log₂1 - log₂x + 2

We know that  log₂1 = 0

g(x) = 0 - log₂x + 2

g(x) =  - log₂x + 2

So the inverse for log₂(x) + 2  is - log₂x + 2.

Un vendedor de celulaes tiene una meta diaria de venta si al momento lleva el Q.2,000.00 de la meta que equivale el 20%
astra-53 [7]

Answer:

Sales goal, S = Q. 10,000

Step-by-step explanation:

  • Let the daily sales goal be S.

<u>Given the following data;</u>

  • Amount sold = Q. 2,000.00
  • Percentage of the sales goal = 20%

To find his daily sales goal;

\frac {20}{100} * S = 2000

0.2 * S = 2000

Dividing both sides by 0.2, we have;

S = \frac {2000}{0.2}

<em>Sales goal, S = Q. 10,000</em>
