7+[9÷(9x1 to the second power)]

EXPLANATION:

We must replace in the equation given the altitude in the variable x ; the exercise is as follows:

The required domain and the range of the given function is (0, ∞) and (-8, -2) respectively.

Given that,
A graph of the function is shown we have to determine the domain and range of the function with the help of the graph.

The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.

Here,
As of the graph,
The graph describes as only the positive real number because the graph only consists of the positive x-axis, so the domain of the function is all positive real numbers. While the ordinate of the graph is describe for -8 to -2 on the negative y-axis thus the rang of the given function lies between -8 to -2.

Thus, the required domain and the range of the given function is (0, ∞) and (-8, -2) respectively.

we have that

The surface area of the pyramid is equal to the area of its square base plus the area of its four triangular faces

step 1

Find out the area of the square base

A=15^2

A=225 ft2

step 2

Find out the area of one triangular face

the area of a triangle is equal to

A=(1/2)(b)(h)

we have

b=15 ft

h ----> is the slant height

To find out the slant height, apply the Pythagorean Theorem

h^2=10^2+(15/2)^2

h^2=100+56.25

h=12.5 ft

therefore

A=(1/2)(15)(12.5)

A=93.75 ft2

step 3

The surface area is equal to

SA=225+4(93.75)

l = 5 in

P = 2(5 in) + 2(2 in)

P = 10 in + 4 in

P = 14 in

Answer:

Colin bought 7 7/8 boxes

Step-by-step explanation:

Let R represent  the number of boxes bought by Ryan and A represent the number of boxes bought by Allan

R = 3 1/2

Convert to improper fraction:
3 1/2 = (3 x 2 + 1)/2 = 7/2

Allan bought 1 3/4 more boxes than Ryan

A = R + 1 3/4

Convert 1 3/4 to improper fraction:
1 3/4  7/4

So A = 7/2 + 7/4 = 14/4 + 7/4 = 21/4

Colin bought 1 1/2 times as many boxes as Allan
C = 1 1/2 x A

Convert 1 1/2 to improper fraction:

1 1/2 = 3/2

So C = 3/2 x 21/4

= 63/8 = 7 7/8 boxes

Answer

Number of possible outcomes for everything = 240 ways

Explanation

The number of possible outcomes can be calculated by taking each of these two groups.

First group contains 2 elements

Number of possible ways to pick the elements = 2! = 2 × 1 = 2 ways

Second group contains 5 elements

Number of possible ways to pick the elements = 5! = 5 × 4 × 3 × 2 × 1 = 120 ways

Number of possible outcomes for everything = 2! × 5! = 2 × 120 = 240 ways

ANSWER and EXPLANATION

We have that the 1 - 5th terms of the sequence are:

2/3, 1, 3/2, 9/4 and 27/8

To plot the graph of this sequence, we have:

=> on the x axis, the term number (i.e. n = 1, 2, 3, 4, 5)

=> on the y axis, the term(i.e. a(n) 2/3, 1, 3/2, 9/4, 27/8)

We will plot the graph of n versus a(n).

Answer:

Answer

Vertex = (-2, -1)

Axis of symmetry: x = -2

The graph of the function is presented below

Explanation

The vertex of a quadratic equation is the point where the graph of the quadratic equation changes from sloping negatively to sloping positively and vice-versa.

The axis of symmetry represents the straight line that divides the graph of the quadratic equation into two mirror parts that are similar to and are mirror images of each other. This axis of symmetry usually passes through the vertex.

To find the vertex, it is usually at the turning point where the first derivative of the quadratic equation is equal to 0.

(df/dx) = 0

f(x) = (x + 2)² - 1

f(x) = x² + 4x + 4 - 1

f(x) = x² + 4x + 3

At the vertex, (df/dx) = 0

(df/dx) = 2x + 4

2x + 4 = 0

2x = -4

Divide both sides by 2

(2x/2) = (-4/2)

x = -2

We can then obtain the corresponding y-coordinate of the vertex

f(x) = (x + 2)² - 1

f(-2) = (-2 + 2)² - 1

f(-2) = 0² - 1

f(-2) = -1

So, the vertex is given as

Vertex = (-2, -1)

Although, one can obtain the vertex from the form in which that equation is given, the general form is that

f(x) = (x - x₁)² + y₁

Comparing that with

f(x) = (x + 2)² - 1

we see that,

x₁ = -2, y₁ = -1

So, Vertex: (-2, -1)

Then, the axis of symmetry will be at the point of the vertex.

Axis of symmetry: x = -2

And for the graph, we just need to obtain a couple of points on the line to sketch that.

when x = 0

f(x) = (x + 2)² - 1

f(0) = (0 + 2)² - 1

f(0) = 4 - 1 = 3

(0, 3)

when y = 0

x = -3 and x = -1

So,

(-3, 0) and (-1, 0)

(-2, -1), (0, 3), (-3, 0) and (-1, 0)

So, with these points, we can sketch the graph.

The graph of this function is presented under answer above.

How is a prime factor discovered?

The simplest method for determining a number's prime factors is to keep dividing the starting number by prime factors until the result equals 1. When we divide the number 30 by its prime factors, we obtain 30/2 = 15, 15/3 = 5, and 5/5 = 1. We received the balance, thus it cannot be factored any further.

Example: 36 can be written as the product of two prime factors, 22 and 32. The prime factorization of 36 is stated to equal the equation 22 32.

Answer:

$5304.25.

Explanation:

The simple interest formula is given by

where

A = future value

P = princple amount

r = interest rate /100

t = time interval.

Now in our case

A = unknown

P = $4900

r = 5.5 / 100

t = 18 / 12 ( we are converting months to years. 18 months = 18 /12 years )

Putting the above values into the simple interest rate formula gives

which simplifies to give

Hence, the future value is $5304.25.
