Mike is working on solving the exponential equation 74^x = 37; however, he is not quite sure where to start. Using complete sentences, describe to Mike how to solve this equation.

Answers

Answer 1

Answer:

Method 1

[tex]74^x = 37[/tex]

Take natural logs of both sides:

[tex]\implies \ln74^x = \ln37[/tex]

Apply the log power rule: [tex]\ln(a)^b=b \ln (a)[/tex]

[tex]\implies x\ln74 = \ln37[/tex]

Divide both sides by ln 74:

[tex]\implies \dfrac{x\ln74}{\ln74} = \dfrac{\ln37}{\ln74}[/tex]

[tex]\implies x= \dfrac{\ln37}{\ln74}[/tex]

[tex]\implies x=0.8389552282...[/tex]

Method 1

[tex]74^x = 37[/tex]

Take logs of base 74 of both sides:

[tex]\implies \log_{74}74^x = \log_{74}37[/tex]

Apply the log power rule: [tex]\log_am^n=n\log_am[/tex]

[tex]\implies x\log_{74}74= \log_{74}37[/tex]

Apply log of the same number as base rule: [tex]\log_aa=1[/tex]

[tex]\implies x= \log_{74}37[/tex]

[tex]\implies x=0.8389552282...[/tex]

Answer 2

Answer:

[tex]x = \log_{74}(37) [/tex]

Step-by-step explanation:

we want to solve the following exponential equation:

[tex] \iff {74}^{x} = 37[/tex]

Taking common logarithm of both sides yields:

[tex]\iff \log{74}^{x} = \log37[/tex]

recall that,

[tex] log( {a}^{x} ) = x log(a) [/tex]

utilizing it yields:

[tex] \iff x \cdot\log{74} = \log37[/tex]

divide both sides by log74:

[tex]\iff \dfrac{ x \cdot\log{74}}{ \log(74)} = \dfrac{ \log37}{ \log(74) }[/tex]

remember that,

[tex] log_b( {a} ) = \frac{log(a)}{log(b)} [/tex]

hence,

[tex]x = \boxed{ \log_{74}(37)} [/tex]

Given the function f(x) = 2x2 - 27, find f(h +2).

Answers

Answer:

f(h + 2) = 2h² +8h - 19

Step-by-step explanation:

f(x) = 2x² - 27

f(h + 2) = 2(h + 2)² - 27

f(h + 2) = 2(h²+4h+4) - 27

f(h + 2) = 2h² + 8h + 8 - 27

f(h + 2) = 2h² +8h - 19

how do I find the area of composite figures​

Answers

The area of the composite figure involving rectangle and trapezium is 810.5cm².

How to calculate the area?

The area can be found by adding the area of the rectangle and trapezium. This goes thus:

Area of rectangle = Length × Width = 15 × 23 = 345cm²

Area of trapezium = 1/2(a + b)h

= 1/2(15 + 34) × 19

= 1/2 × 49 × 19

= 465.5cm²

The area will now be:

= 345cm² + 465.5cm²

= 810.5cm²

Ryan is working on his first budget. He has placed all of the fixed expenses on the budget shown and then would like to use the information to evaluate his variable expenses. Ryan's take-home pay is 2,500 each month. Complete the table below the answer the questions below.
please help me
complete the table and answer the four questions below if you tell me how to do I'll be happy to mark you brainlest!!!

1) what percent of his monthly budget do his transport costs account for?

2) what percent of his monthly budget has he accounted for?

3) Ryan would like to save 10% of his take-home pay towards retirement. How much would he be able to save each month?
4) Assume that Ryan does save 10% for retirement. If he allocates the remainder of his take-home pay to entertainment compromise of the total monthly budget? How much will be budgeted towards entertainment?

Answers

The percent of his monthly budget that his transport costs account for will be 17.8%.

How to calculate the percentage?

The percent of his monthly budget that his transport costs account for will be:

= 325/(800 + 450 + 125 + 325 + 125) × 100

= 325/1825 × 100

= 17.8%

The percent of his monthly budget has he accounted for will be:

= 1825/2500 × 100

= 73%

When he saves 10% of his take-home pay towards retirement, the amount saved will be:

= 10% × $2500

= $250

The percent of Rayan's monthly budget that his transport costs account for will be 17.8%.

1. The proportion of his monthly budget that his transit expenses make up is:

= 325/(800 + 450 + 125 + 325 + 125) × 100

= 325/1825 × 100

= 17.8%

The proportion of his monthly budget that he has already accounted for is:

= 1825/2500 × 100

= 73%

He will save the following sum for retirement if he sets aside 10% of his after-tax income:

= 10% × $2500

= $250

The answer is $250.

2. To find the percentage of his monthly budget accounted for by transport costs, we add up the amounts for Car Payment and Gas:

$325 + $125 = $450.

Then we calculate the percentage: (450 / 2500) x 100% = 18%. Therefore, his transport costs account for 18% of his monthly budget.

3. To find the percentage of his monthly budget accounted for overall, we sum up all the amounts in the table:

$800 + $450 + $125 + $325 + $125 = $1,825.

Then we calculate the percentage: (1825 / 2500) x 100% = 73%. Therefore, he has accounted for 73% of his monthly budget.

4. To calculate how much Ryan can save each month for retirement, we take 10% of his take-home pay:

10% of $2,500 = $250.

Thus, he can save $250 each month for retirement.

Write Down 3 numbers where the following are true:the total of the three numbers is 20.The product of the three numbers is 90

Answers

Answer:

1, 9 and 10.

Step-by-step explanation:

Let the 3 numbers be x, y  and z, then

x + y + z = 20

xyz = 90

Assuming the numbers are whole numbers lets find the prime factors of 90:

90 = 2*3*3*5

So we need to combine these factors to fit the 2 eqautions.

Now 90 = 9 * 10

= 1 * 9 * 10

If we include 1 as one of the 3 numbers then 1, 9 and 10 will fit the bill.

O D.
To calculate a point estimate, we
need to know the sample size.

Answers

Answer: Choice D

To calculate a point estimate, we need to know the sample size.

===========================================================

Explanation:

Let's go through the answer choices.

A) False. A sample statistic could equal to the population parameter. It won't always happen, but it might happen sometimes (in rare cases). B) False. Point estimates are only defined for populations. They estimate a population parameter. For example, the sample mean xbar is a point estimate of the population mean (mu).C) False. In practice, we will hardly know anything about the population. This includes the population size. The goal of statistics is to measure population parameters by using sample statistics as estimation methods.D) True. We can easily calculate the sample size because it is relatively much smaller compared to the population. Plus, when selecting the sample, the sample size is often pre-determined to some set number. The sample size will help us determine things like the sample mean and the sample proportion.
