I need some help please. Write a function rule to describe each statement...

1 answer:

4 0

You could see the pattern

it cost 3.8 cent to print 1 dollar,

It cost 2 x 3.8 cents to print 2 dollar

it cost 3 x 3.8 cents to print 3 dollar

First equation
f(x) = 3.8 x

Same with second equation,
f(x) = 15x

for equation 3, it would be :

y = 1.50 x - 0.8x

Hope this helps

The word "less than" represent what operation?

bixtya [17]

Answer:

The term 'less than' is used to indicate the relationship between two values.

The term 'less than' symbolically represented as '<'.

Step-by-step explanation:

The term 'less than' is used to indicate the relationship between two values.

It expresses that one value will be lesser than the other.

The term 'less than' symbolically represented as '<'.

We can implement certain operations like comparing values, heights, and numbers.

For example, there are 3 pencils in one bag A, and 8 pencils in bag B.

When we compare the two, we can easily observe that bag A has fewer pencils than bag B.

Thus,

Pencils in Bag A < Pencils in Bag A

3 < 8

What are the exact solutions of x^2 − 3x − 7 = 0?

bulgar [2K]

<u>Given</u>:

The given equation is $x^{2} -3x-7=0$

We need to determine the exact solutions of the equation.

<u>Exact solution:</u>

The exact solution of the equation can be determined by solving the equation using quadratic formula,

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

From the equation the values are a = 1, b = -3 and c = -7

Thus, substituting these values in the equation, we get;

$x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}$

$x=\frac{3 \pm \sqrt{9+28}}{2}$

$x=\frac{3 \pm \sqrt{37}}{2}$

Thus, the exact solutions of the given equation is $x=\frac{3 \pm \sqrt{37}}{2}$

Hence, Option A is the correct answer.

Based on the figure below, what is the value of x? (5 points) A right angle is shown divided in two parts. The measure of the an

Orlov [11]

Answer:

Hello! answer: 9

Step-by-step explanation:

Assuming this is a complementary angle (meaning it will add up to 90 degrees)

5 × 9 = 45 45 + 15 = 60 60 + 30 = 90 therefore x = 9 Hope that helps!

In the diagram of right triangle ABC shown below, AB = 14 and AC = 9. What is the measure of angle A to the nearest degree?

olga_2 [115]

This question is incomplete because it lacks the diagram of the right angled triangle. Find attached to this answer the diagram of the right angle triangle.

Answer:

d-50

Step-by-step explanation:

Looking at the attached diagram, the only way to solve for this is the use of the trigonometric function. The trigonometric function to be used is the cosine function.

From the diagram, we are given

Hypotenuse = AB = 14

Adjacent = AC = 9

The measure of angle A to the nearest degree is calculated as:

cos θ = Adjacent / Hypothenuse

cos θ = 9/14

θ = cos -¹ (9/14) or arccos(9/14)

θ = 49.994799115°

To the nearest degree = 50°

Therefore,the measure of angle A to the nearest degree = 50°

Hello I need help jsjdbdjdjdjdkdkd

Alexandra [31]

I'll assume the question is: what's the volume?

It's two L×W×H rectangular prisms (aka boxes) put together

The bottom one is 2×3×4

The top one is 5×4×1

Volume = 2×3×4 + 5×4×1 = 24 + 20 = 44

Answer: 44 cubic feet
