Answer:

Surface area = 222 square cm

Explanation:

Given the following data

Length = 3 cm

Height = 9 cm

Width = 7 cm

Surface area = 2(wl + hl + hw)

Surface area = 2(7 * 3 + 9 * 3 + 9 * 7)

Surface area = 2( 21 + 27 + 63)

Surface area = 2( 111)

Surface area = 222 square cm

Therefore, the surface area is 222 square cm

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

Step 02:

y = 4x + 8

To tell if (3, 20) is a solution, we will substitute the value of x = 3 and y= 20

into the equation to see if the left-hand side equals the right-hand side of the equation

So, upon substituting

20 = 4 x 3 + 8

20 = 12 + 8

20 = 20

Since the left-hand side of the equa

Number of sodas sold = 80

Number of hot dogs sold = 23

Let th number of sodas be xs

Let the number of hot dogs be h

The vendor sold a combined total of 103 sodas and hot dogs

s + h = 103............(1)

The nmber of soda sold was 57 more tha n the number of hot dogs sold

s = h + 57........()

Subtitute equation (2) into equation (1)

h + 57 + h = 103

2h = 103 - 57

2h = 46

h = 46/2

h = 23

Substitute h = 23 into equation (2)

s = 23 + 57

s = 80

Number of sodas sold = 80

Number of hot dogs sold = 23

Answer:

A(-6, 1)

B(-6, -7)

C(7, -9)

D(-8, -8)

Explanation:

From the graph, we can see that at point A, x = -6 and y = 1. Therefore, the ordered pair can be written as A(-6, 1)

At point B, x = -6 and y = -7. The ordered pair can be written as B(-6, -7)

At point C, x = 7 and y = -9. Its ordered pair will be C(7, -9)

At point D, x = -8 and y = -8. Its ordered pair will be D(-8, -8)

x³ + 2x² - 9x - 18 is the polynomial function of least degree with integral coefficients that had the zeros -3 , 3 , -2.

Given, the zeros of a polynomial be,

-3 , 3 and -2

As, the polynomial has 3 zeros then the degree of the polynomial is also be , 3.

Let the polynomial be,

p(x) = (x - (-3))(x - 3)(x - (-2))

p(x) = (x + 3)(x - 3)(x + 2)

On multiplying the factors, we get

p(x) = (x² - 3²)(x + 2)

p(x) = (x² - 9)(x + 2)

p(x) = (x³ - 9x + 2x² - 18)

p(x) = x³ + 2x² - 9x - 18

So, x³ + 2x² - 9x - 18 is the polynomial function of least degree with integral coefficients that had the zeros -3 , 3 , -2.

Hence, x³ + 2x² - 9x - 18 is the polynomial function of least degree with integral coefficients that had the zeros -3 , 3 , -2.

Given:

Two bags have a total weight of 8 3/4 pounds.

What could be their individual weights?

To answer the question, we will select the option that gives a sum of 8 3/4

We will check the options:

A. 7 pounds and 3/4 pounds

The sum = 7 + 3/4 = 7 3/4 pounds

So, option A is wrong

B. 3 1/4 pounds and 5 1/2 pounds

The sum = 3 1/4 + 5 1/2 = 8 3/4

So, option B is correct

C. 4 3/4 pounds and 4 pounds

The sum = 4 3/4 + 4 pounds = 8 3/4 pounds

So, option C is correct

D. 8 pounds and 1/4 pounds

The sum = 8 + 1/4 = 8 1/4

So, option D is wrong

E. 6 pounds and 2 3/4 pounds

The sum = 8 3/4

So, E is correct

The answer will be: B and C and E

Here, we want to simplify the expression

To do this, we shall use the term outside the bracket to multiply the terms inside the brackets before we proceed to add them together

We have this as follows;

We have the following problem:

Using the kinematic equation, we know that for movements with constant acceleration the position is

I already wrote the variables convenient for our problem, where

t = time (s)

h₀= initial height (m)

v₀ = initial velocity (m/s)

g = gravity acceleration (m/s²)

h = height after t seconds

We also know that

t = independent variable

h₀= 10m

v₀ = 56 m/s

g ≅ 10 m/s²

h = dependent variable

Therefore our quadratic will be

Now we can answer the question in fact.

a)

The rocket will hit the ground when the height is equal to zero, hence, h(t) = 0. In fact, we are looking for the zeros of the quadratic

See that we have one negative zero, but we will ignore that because it's physically impossible, therefore the rocker will reach the ground after 11.38 seconds

b)

To find the maximum height we must find the max value of the quadratic, we know that the vertex of a quadratic is its max/min, also, we can write it as

Where

Is the vertex. Here, we want to find the y coordinate, because y here is the height, therefore

The max height of the rocket is 166.8m

c)

Now we have a similar problem, it's also the vertex but now the coordinate x, that here, represents the time, then

The rocket will reach the maximum height after 5.6 seconds.

We want to expand the expressions given:

1. 6 x 20 = 6 x 2 x ____

To do this, we have to divide 20 by 2, because 20 was expanded to give 2 x __.

20 divided by 2 is 10, so the answer is:

6 x 20 = 6 x 2 x 10

2. 5 x 100 = ___ x 10 x 10

This is straightforward, since 10 x 10 is 100.

The answer is:

5 x 100 = 5 x 10 x 10

From the question we're told that the sum of two consecutive numbers is 85,

Let the 1st number by y,

And the consecutive number be y+1

So, the sum of these two numbers will be equal to 85;

Let's go ahead and solve for y in the above equation;

So the first number is 42.

Let's find the consecutive number;

Therefore, the "first number = 42" and "consecutive number = 43"

EXPLANATION

The graph of the parent function f(x) = [x] is

The function has the value of x until the next integer. So we have:

f(x) = 0 when x = 0 until x = 1, and then it changes to f(x) = 1. This is for all values of x. We can say that the function "jumps" on each integer and then keeps its value.

If we do a vertical shift of 2 units we have to add 2 to each value of the parent function. This way the shifted function is f(x) = 2 when x = 0 until x = 1, and then it jumps to f(x) = 3:

(a) From the graph, the average recent college graduate engineer makes $65000, and the average recent college graduate accountant makes $40000. Therefore, an engineer makes $65000 - $40000 = $25000 more than the accountant.

(b) In marketing, the average graduate degree holder makes approximately $80000 (rounded down to the nearest thousand), and the average recent college graduate makes approximately $35000 (rounded down to the nearest thousand). Therefore, the average graduate degree holder makes $80000 - $35000 = $45000 more than the average recent college graduate

(c) graduate degree holder architect average earning: $75000 (rounded down to the nearest thousand)

average recent college graduate architect average earning: $35000 (rounded down to the nearest thousand)

The percent increase is computed as follows:

(d) graduate degree holder nurse average earning: $ 80000 (rounded down to the nearest thousand)

average recent college graduate nurse average earning: $45000 (rounded down to the nearest thousand)

The percent increase is computed as follows:

(e) Comparison between average earning of a degree holder and of a college graduate for each area:

Engineers

Increase = degree holders - college graduate

Increase = 110000 - 65000

Increase = 45000

Nurses

Increase = degree holders - college graduate

Increase = 80000- 45000

Increase = 35000

Finance

Increase = degree holders - college graduate

Increase = 100000 - 45000

Increase = 55000

Accountant

Increase = degree holders - college graduate

Increase = 85000 - 40000

Increase = 45000

Architects

Increase = degree holders - college graduate

Increase = 75000 - 35000

Increase = 40000

Marketing

Increase = degree holders - college graduate

Increase = 80000 - 35000

Increase = 45000

The greatest increase from college graduates to degree holders is in Finance
