Evaluate the stacked function machines for an input of 21*

Answer:

No, the given is not a function.

Step-by-step explanation:

I am confused if the last half of the numbers belong to a y value or not, but the answer is the same regardless.

If all numbers provided are "x", then no; the given does not represent a function. This is because the "x" value has duplicates, which indicates a non function.

Even if the last 5 numbers belong to f(x), or "y", the given is still not a function. the duplicated number is "9", and the 9's would be an x value regardless of the form of the given information.

Answer: 3x=57 there will be 19 flowers in each arrangement

Answer:

Step-by-step explanation:

Ok, the shop has 57 total daisies.  They are working on 3 flower arrangements that need the same number of daisies in each.

This is a division problem.  We need to divide to see how many daisies would fit in each arrangement.

So, the equation would be d=57÷3 or 57÷3=d.  Either works! Then, to find the answer, just divide 57 divided by 3.

Answer:

\(-\frac{8}{5}\)

Step-by-step explanation:

Method 1

Count the slope, use \(\frac{rise}{run}\)

Counting the slope, we get \(-\frac{8}{5}\)

Method 2

Use the formula \(\frac{y2-y1}{x2-x1}\)

We have two pairs coordinates, (-1, 4) and  (4, -4)

Apply the formula

\(\frac{(-4)-4}{4-(-1)}\\\)

A city starts with a population of 500,000 people in 2007. Its population declines according to the equation

P(t) = 500,000e -0.099t

where P is the population in t years later. Approximately when will the population be half the initial amount?

Answer:

2014

Step-by-step explanation:

Given the exponential growth function :

P(t) = 500,000e^-0.099t

Where P is population in t years later

When the population will 1/2 the initial amount

1/2 the initial amount = 1/2 * 500,000 = 250,000

P(t) = 250,000

250,000 = 500000e^-0.099t

250,000/500000 = e^-0.099t

In(0.5) = - 0.099t

t = −0.69314 / - 0.099

t = 7.0014

t = 7

Year which population = 500,000 = 2007

Hence, half the population will be attained on (2007 + 7) = 2014

After 7 years population of the city will be half of the initial amount.

Population function:

\(P(t) = 500000 e^{-0.099t}\)

Initial population means population at t=0

P(0) = 500000

Half of initial population = 250000

So, we need to calculate the time t when the population will be half of the initial amount.

\(250000= 500000 e^{-0.099t}\\\\e^{-0.099t} = \frac{1}{2}\)

Taking log both sides

-0.099t (log e)= log (1/2)

The logarithm of e is 1 when considering the base of the log as e.

So, -0.099 t= -0.693

t=7

Therefore, After 7 years population of the city will be half of the initial amount.

We have to given that;

Function is,

⇒ F' (x) = 16x³ + 14x + 7

Now, We get;

Integrate both side;

F (x) = 16 x⁴ / 4 + 14x²/2 + 7x

F(x) = 4x⁴ + 7x² + 7x + c

Since, F (1) = - 5

Hence,

F (x) = 4 (1)⁴ + 7 (1)² + 7 (1) + c

- 5 = 4 + 7 + 7 + c

c = - 22

Answer: 336+6i

The key to solving this problem is to choose which parts you should solve first.

2i(3-4i)+8(4-5i)(4+5i)​

let's divide this expression to three parts:

2i(3-4i), 8 and (4-5i)(4+5i)​

first let's solve 2i(3-4i):

2i(3-4i) =

2i × 3 + 2i × -4i =

6i - 8i² =

6i + 8

(4-5i)(4+5i)​:

(4-5i)(4+5i)​ =

16 + 20i - 20i -25² =

16 + 25 =

41

8(4-5i)(4+5i)​:

8(4-5i)(4+5i)​ = 8 × 41 = 328

Now let's put back these parts:

2i(3-4i)+8(4-5i)(4+5i)​ =

6i + 8 + 328 =

6i +336 OR 336 +6i

Answer:

2.6 kilometers

Step-by-step explanation:

To find the circumference of a circle, we can use the formula:

Circumference = π * diameter

Given that the diameter of the volcanic crater is 840 meters, we can substitute this value into the formula:

Circumference = π * 840

Using the approximate value of π as 3.14159, we can calculate the circumference:

Circumference = 3.14159 * 840

Circumference ≈ 2643.1796 meters

To convert the circumference to kilometers, we divide the value by 1000:

Circumference in kilometers = 2643.1796 / 1000

Circumference ≈ 2.6432 kilometers

Therefore, the circumference of the rim of the volcanic crater is approximately 2.6 kilometers (rounded to 1 decimal place).

The coefficient of the variable term (the term with the variable), then it would be 9.

The expression 9d+c+1 consists of three terms, namely 9d, c, and 1. Each of these terms has a coefficient, which is the numerical factor that multiplies the variable or constant in the term. In this case, the first term, 9d, has a coefficient of 9, since it represents 9 times the variable d. The second term, c, has a coefficient of 1, since it represents 1 times the variable c.

However, there is no second term in this expression, since there are only three terms and each one is separated by a plus sign. The third term, 1, has a coefficient of 1, since it represents 1 times the constant 1. Therefore, the coefficient of the second term in 9d+c+1 is not applicable, as there is no second term in the expression.

According to the given information, the tuition at the University has been rising at an average annual rate of 7.5% from 1974-2022. To calculate the cost of four years at university beginning 20 years from now, we need to consider the future value of money.

To start, let's assume the current cost of one year at the University is $x. We can calculate the future value of $x after 20 years using the compound interest formula:

Future Value = Present Value * (1 + interest rate)^number of periods

In this case, the interest rate is 7.5% or 0.075 and the number of periods is 20. Plugging these values into the formula, we get:

Future Value = x * (1 + 0.075)^20

Now, we need to calculate the cost of four years at the University. Since each year's tuition is expected to increase at the same rate, we multiply the future value by 4:

Total Cost = 4 * x * (1 + 0.075)^20

This expression represents the cost of four years at university beginning 20 years from now. To find the value, you can substitute the current cost of one year at the University for x and evaluate the expression using a calculator.

There is no relationship between the number of movies and the number of sleep hours.

It is always a thing of importance to show data by the use of a scatter plot. The scatter plot must always have two axes. The vertical (y axis ) and the horizontal (x axis). It is always common to plot the independent variable on the x axis and the dependent variable on the y axis.
