c) Determine the location and values of the absolute maximum and absolute
minimum for the given function:
f(x) = (-x + 2)4, where 0 <x<3​

Answers

Answer:

The absolute maximum on the interval 0 < x < 3 is at x = 2 and f(2) = 0. Since x = 2 can only give an absolute maximum, so there is no absolute minimum.

Step-by-step explanation:

f(x) = (-x + 2)⁴

to find the absolute maximum and minimum values, we differentiate f(x) with respect to x.

So df(x)/dx = f'(x) = 4(-x + 2)³

The maximum and minimum values are obtained when f'(x) = 0

So,  4(-x + 2)³ = 0

⇒  (-x + 2)³ = 0

⇒ -x + 2 = 0

-x = -2

x = 2

Now, f(2) = (-2 + 2)⁴ = 0⁴ = 0

So, the absolute maximum on the interval 0 < x < 3 is at x = 2 and f(2) = 0. Since x = 2 can only give an absolute maximum, so there is no absolute minimum.

you spin the spinner once
What is P(5)?

Answers

0-10

A spinner is split into 11 different pieces so you are less likely to land on five than the other numbers.

The probability of getting 5 on spinner is 0.25.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, on the spinner there are four numbers {3, 4, 5, 6}.

Number of favorable outcomes = 1

Total number of outcomes = 4

So, P(5) = 1/4

= 0.25

Therefore, the probability of getting 5 on spinner is 0.25.

Find the area of each triangle
8 yd
8 yd

Answers

Answer:

Area of triangles 1 = 18 ft²

Area of triangles 2 = 16 in²

Area of triangles 3 = 90 yd²

Step-by-step explanation:

Given:

1] Height of triangle = 4 ft

Base of triangle = 9 ft

2] Height of triangle = 4 in

Base of triangle = 8 in

3] Height of triangle = 12 yd

Base of triangle = 15 yd

Find:

Area of triangles

Computation:

Area of triangles = (1/2)(Base)(Height)

Area of triangles 1 = (1/2)(4)(9)

Area of triangles 1 = 18 ft²

Area of triangles 2 = (1/2)(4)(8)

Area of triangles 2 = 16 in²

Area of triangles 3 = (1/2)(12)(15)

Area of triangles 3 = 90 yd²

What is the length of AB?

Answers

Answer:

B. 6

Step-by-step explanation:

We can see that through angles A and C that this triangle is an isosceles triangle. Knowing that, we can set up the equation 3x=4x-2. We can simplify by adding 2 two both sides. We get the equation 3x+2=4x. Then we subtract 3x from both sides. So therefore, 2=x. Length AB is 3x so we would do 2*3, which is equal to 6. So your answer would be B. 6.

Find the slope and the y-intercerpt f(x) = 8 -7/8x​

Answers

Answer:

slope = -7/8

y-intercept = 8

Step-by-step explanation:

slope intercept form is

y = mx + b

m is slope

b is y-intercept

------------------------

f(x) = 8 - 7/8x​

Rearrange into slope intercept form

f(x) = -7/8x​ + 8

slope = -7/8

y-intercept = 8

Answer:

Slope = -7/8

Y-intercept = 8

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

f(x) = 8-7/8x​

Given the above, rearrange it in slope-intercept form to help us find the slope and y-intercept:

f(x) = -7/8x​+8

Now, we can see clearly that -7/8 is in place of m and 8 is in place of b. This means that -7/8 is the slope of the line and 8 is the y-intercept.

I hope this helps!

what is the price of a mobile set whose marked priced is Rs.15000 and 13% vAT was levied after allowing 20%discount on it.​

Answers

Answer:

Rs. 18080

Step-by-step explanation:

Given :

Marked price = Rs. 20000

Discount = 20%

Discounted price = (100-20)% * marked price

Discounted price = 80% * 20,000 = Rs. 16,000

The VAT = 13%

VAT charge = 13% * 16,000 = Rs. 2080

Final price = discounted price + VAT charge

Final price = 16000 + 2080 = Rs. 18080

Soda is sold in aluminum cans that measure 7 inches in height and 2.8 inches in diameter.
How many cubic inches of soda are contained in a full can?

Answers

Answer:

Volume of soda in soda can = 43.1 inches³ (Approx.)

Step-by-step explanation:

Given:

Height of soda can = 7 inches

Diameter of soda can = 2.8 inches

Find:

Volume of soda in soda can

Computation:

Radius of soda can = Diameter of soda can / 2

Radius of soda can = 2.8 / 2

Radius of soda can = 1.4 inches

Volume of soda in soda can = Volume of cylinder

Volume of soda in soda can = πr²h

Volume of soda in soda can = (3.14)(1.4)²(7)

Volume of soda in soda can = (3.14)(1.96)(7)

Volume of soda in soda can = 43.1 inches³ (Approx.)

Calculate the total cost, total depreciation, and annual depreciation for the following assets by using the straight-line method. Cost Shipping Charges Setup Charge Total Cost Salvage Value Estimated Useful Life (years) Depreciation Total Annual
1. $5,600 $210 $54 ______ $600 6
2. $16,900 $310 0 ______ $1900 4

Answers

Answer:

a. For Asset 1, we have:

Total cost = $5,864

Total depreciation = $5,264

Annual depreciation = $877.33

b. For Asset 2, we have:

Total cost = $17,210

Total depreciation = $15,310

Annual depreciation = $3,827.50

Step-by-step explanation:

Note: The data in this question are merged together. They are therefore sorted before answering the question. See the attached pdf for the complete question with the sorted data.

Also note: See the attached excel file for the presentation of the data in the question with the answers (in bold red color).

The explanation of the answers is now given as follow:

Straight line method is a method of calculating depreciation and amortization of an asset by dividing the difference between the total cost and salvage value of an asset by its estimated useful life.

Therefore, wee have:

a. For Asset 1, we have:

Total cost = Cost + Shipping Charges + Setup Charge = $5,600 + $210 + $54 = $5,864

Total depreciation = Total cost - Salvage Value = $5,864.00 = $600 = $5,264

Annual depreciation = Total depreciation / Estimated Useful Life = $5,264 / 6 = $877.33

b. For Asset 2, we have:

Total cost = Cost + Shipping Charges + Setup Charge = $16,900 + $310 + $0 = $17,210

Total depreciation = Total cost - Salvage Value = $17,210 - $1,900 = $15,310

Annual depreciation = Total depreciation / Estimated Useful Life = $15,310 / 4 = $3,827.50
