The first equation given in the question as, y = 1^x is not exponential.

What do you mean by exponential?

A mathematical function with the form f (x) = a^x is an exponential function. "x" is a variable, while "a" is a constant that serves as the function's base and must be bigger than 0. The transcendental no., or roughly 2.71828, is the most often used exponential function on regular basis.

The equation, y = 1^x is not an exponential because for any integer value of x, y always equals to zero. Which makes it simple equation and not an exponential equation.

Answer:

7 hours

Step-by-step explanation:

25x + 25 = 200.

25x = 175

175/25 = 7.

Answer:

25 + 35h = 200

and

h = 5

(5 hours)

Step-by-step explanation:

you have 200.

costs:

35 per hour

and

25 fee

h will represent the total hours spent renting a boat

25 + 35h = 200

now we will do inverse operations

subtract 25 from both sides

35h = 175

now divide both sides by 35

h = 5

If Gloria deposited $500 into a bank account that earned 7.5% simple interest each year and she earned $225 in interest before closing the account, then the number of years that the money in the account is 6 years

The deposited amount = $500

The simple interest = 7.5%

The interest she earned = $225

Then the final amount = The deposited amount + The interest she earned

= 500+225

= $725

The equation of simple interest

A = P(1+rt)

Where A is the final amount

P is the initial amount

r is the interest rate

t is the time period

725 = 500(1+(7.5/100)×t)

(1+0.075t) = 1.45

0.075t = 0.45

t = 0.45/0.075

t = 6 years

Hence, if Gloria deposited $500 into a bank account that earned 7.5% simple interest each year and she earned $225 in interest before closing the account, then the number of years that the money in the account is 6 years

Problem

At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two small fries have a total of 1,330 calories. How many calories does each item contain?

Solution

For this case we can set up the following notation

x= number of cheeseburgers

y= small fries

4x +5y= 2310

3x + 2y= 1330

From the first equation we can solve for x and we got:

x= 577.5 - 5/4 y

And now we can replace this into the second equation and we got:

3(577.5 -5/4 y) +2y= 1330

And we can solve for y:

1732.5 - 15/4 y + 2y = 1330

-7/4 y = -402.5

y= 230 cal

And solving now for x we have:

x= 577.5 - 5/4 (230) = 577.5 - 287.5 = 290 cal

One die has a total outcome of 6 elements (1, 2, 3, 4, 5, 6). Now, if we roll two dice, each time you roll a number on the first die, there are another 6 possible outcomes for the second die.

Therefore, the number of elements in the sample space would be:

There would be 36 elements in the sample space.

Let's define first the variables.

let H be the number of bags of the type that cost 3.25 and P the number of bags of the type that cost 2.75.

since they sold a total of 156 bags we have that H+P=156

and from the other condition we obtain 3.25H+2.75P=455

now we can solve the system of equations.

from the first equation H=156-P

substituing the previous equality in the second one we obtain:

now that we have P, we can replace it in the first equation obtaining that H=50

then the answer will be that they sold 50 bags of $3.25 and 106 bags of $2.75

The equation is

Therefore x<-2. The number line representation is

Desired Outcome:

1. Domain

2. Range

Determine the domain of the function

Note: We want to include only input values that do not require the denominator to be 0 when there is a denominator. As a result, we'll set the numerator to 0 and solve for x.

We'll now remove 4 from the domain. All of the answers are real numbers x > 4 or x < 4. We will also use Union notation to combine the two sets.

That is:

Determine the range of the function

Set x to 4 to find y

We'll also remove 3 from the range. All of the answers are real numbers y > 3 or y < 3. We will also use Union notation to combine the two sets.

The standard score for the given X value is -0.06

Standard Score

Standard score or Z - Score is inversely varies with the standard deviation and directly varies with the difference of the raw score and the mean score.

The formula to calculate standard score is

z - score = (X - μ)/σ

Where

Z = standard score

x = observed value

μ = mean of the sample

σ = standard deviation of the sample

Given,

Here we have the value of X = 83, μ=88.1 and σ=87.

Now, we need to find the standard score for this values and we have also round off the result to two decimal places.

Apply the given values on the z-score formula, then we get,

z-score = (83 - 88.1)/87

When we simplify the numerator, then we get,

z - score = -5.1/87

After the division of these numbers we get the value of z-score as,

z - score = -0.0586

When we round off the result into two decimal place then we get the value of standard score as -0.06.
