Answers

Solution (a):

~Let's change 9.9² to 10² since we have to estimate.~

We know that:

10² = 100Given expression: 9.9² × 1.79

Solving the expression:

9.9² × 1.79=> 10² × 1.79=> 100 × 1.79=> 179

The estimated value of 9.9² × 1.79 is 179.

Solution (b):

~Let's change √97.5 to √100 and 1.96 to 2 since we have to estimate.~

We know that:

√100 = 10Given expression: √97.5 ÷ 1.96

Solving the expression:

√97.5 ÷ 1.96=> √100 ÷ 2=> 10 ÷ 2=> 5

The estimated value of √97.5 ÷ 1.96 is 5.

A sculpting tool is in the shape of a solid triangular prism. The tool is made of 12 in. 3 of metal and is 4 in. Long. What is the height of the base if it is 2 in. Wide? 1. 5 in. 3 in. 48 in. 96 in.

Answers

The height of the base if it is 2 in. Wide is 3 inches

what is the height of the base of the prism?

The volume of rectangular prism =  [tex]\dfrac{1}{2} \times Lenght \times Base \times hieght[/tex]

The volume of given rectangular prism = [tex]12 inch ^{3}[/tex]

Length of prism = 4 inch

The base of prism = 2 inch

By putting the values in the formula

[tex]12= \dfrac{1}{2} \times 4 \times 2\times Height[/tex]

Answers

Answer:

Number line graph with a closed circle on 120 and shading to the right.

Step-by-step explanation:

Because they have collected 30 dollars already and must collect at least 150 dollars, the closed circle would go on 120, going to the right. (150-30=120)

Part A: What do the x-intercepts and maximum value of the graph represent in context of the described situation?
Part B: What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and
profit for the company in the situation described?
Part C: What is an approximate average rate of change of the graph from x = 1 to x = 3, and what does this rate represent in
context of the described situation?

Answers

The x intercept of the given graph of the company's profit is where the curve of the graph crosses the x-axis.

How to determine the x-intercept

In this figure, the graph crosses the x-axis at x = 0 and x = 6

This represents the profit is 0 when the price is $0 and $6, respectively

The maximum value

This represents the maximum profit that can be made.

From the graph, the maximum profit is $120

The increasing and the decreasing interval

From the graph, the graph increases from x = 0 to x = x = 3, and it decreases from x = 3 to x = 6

These intervals represent when the profit increases, and when it decreases

The average rate of change

This is calculated as:

[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]

So, we have:

[tex]m = \frac{f(3) - f(1)}{3 - 1}[/tex]

[tex]m = \frac{f(3) - f(1)}{2}[/tex]

Substitute known values

[tex]m = \frac{120 - 60}{2}[/tex]

[tex]m = \frac{60}{2}[/tex]

Simplify

[tex]m = 30[/tex]

Hence, the average rate of change from x = 1 to x = 3 is a profit of $30 per unit sale

Find the 95th term of the arithmetic sequence 4, -5, -14

Answers

Answer: -842

Step-by-step explanation:

To find n95, we have to use the equation aₙ = d * n + a₁ - d

a₁ is the first term, which here is 4. d is the common difference, which we can find out but seeing what we can add pr subtract from 4 to -5 which also equals -5 to -14, in this equation, the common difference would be -9 as it goes down by 9 every term. Once we plug these into the equation, we get

a₉₅ = -9 * n + 4 - (-9)

We can solve this for - aₙ = -9n + 13

Now that we have our equation to find a term, we can plug in n for 95 for

-9(95) + 13

Which equals -842

Option B

5 1/2 = 5 + 0.5 = 5.5

Option D

5.500 = 5.5

Looking at the options, we can see that the result of Option A, B, and D are same.

This means that the odd one is Option C.

Which equation is translated 5 units up from f(x) = 3^x

Transformations of Exponential Functions

The parent exponential function is the following:

[tex]f(x)=b^x[/tex], where b is the base.

We can apply many different types of transformations to this function:

a ⇒ describes vertical stretchk ⇒ describes horizontal stretchd ⇒ describes horizontal translationc ⇒ describes vertical translation

Solving the Question

In this question, we are working with vertical translation.

When a function is translated up, c is positive.When a function is translated down, c is negative.

We are translating the given function [tex]f(x)=3^x[/tex] 5 units up. This means that we will be adding 5 to the function:

Here is a system of linear equations
2x+3y=14
4x-3y=10

Which would be more helpful for solving the system: adding the two equations or subtracting one from the other?

Answers

Answer:

adding the 2 equations

Step-by-step explanation:

2x + 3y = 14 → (1)

4x - 3y = 10 → (2)

since the coefficients of the y- terms are opposites then adding will eliminate y

add (1) and (2) term by term

6x + 0 = 24

6x = 24 ( divide both sides by 6 )

x = 4

substitute x = 4 into either of the 2 equations and solve for y

substituting into (1)

2(4) + 3y = 14

8 + 3y = 14 ( subtract 8 from both sides )

3y = 6 ( divide both sides by 3 )

y = 2

solution is (4, 2 )

A wire is in the shape of a rectangle of length 14cm. Find its breadth if the same wire is re- bent into a square of side 13cm. Also find out their areas and write which one encloses more area, the rectangle or square.

Answers

Length= 40cm

Breadth= 22cm

Perimeter of the rectangle= Length of the wire

=2(l+b)= 2(40cm + 22cm)

=2\times62cm = 124cm

Now, the wire is rebent into a square.

Perimeter= 124cm

4\times side=124

Therefore side= \frac{124}{4}cm= 31cm

So, the measure of each side= 31cm

Area of rectangular shape= l\times b

=40cm\times22cm

=880cm^2

Area of a square shape= \left(Side\right)^2

=\left(31\right)^2=961cm^2

Since 961cm^2\ >\ 880cm^2

Hence, the square encloses more area.

Answer:

See below.

Step-by-step explanation:

Area by square = 169

Area by rectangle = 14 x 12 = 168
