Choose the polynomial that is written in standard form.

−3x5 + 4x3 + 10x2
−8x + 4x4 + 3x3
x4 + 4x3 + 10x4
x6 + 4x3 + 10x7

Answers

Answer:

A. −3x⁵ + 4x³ + 10x²

Step-by-step explanation:

The standard form means that the terms are ordered from biggest exponent to lowest exponent.

Verify the answer options

A. −3x⁵ + 4x³ + 10x²

5, 3, 2 - correct order  

B. −8x + 4x⁴ + 3x³

1, 4, 3 - incorrect order

C. x⁴ + 4x³ + 10x⁴

4, 3, 4 - incorrect order

D. x⁶ + 4x³ + 10x⁷

6, 3, 7 - incorrect order

Answer:

[tex] { - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

Step-by-step explanation:

For a polynomial to be in standard form, it must satify the conditions below:

1) It must not contain like terms

2) The exponents (powers) must be written in descending order

That is, the polynomial must be of the form

[tex]f(x) = {ax}^{n} + {bx}^{n - 1} + {cx}^{n - 2} + . \: . \: . \: . \: . \: mx + n[/tex]

Where a, b, c, m, n, are coefficients/constants

The only option that satifies the above conditions, and follows the pattern f(x) shown is:

[tex]{ - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

A climber is on a hike. After 4 hours he is at an altitude of 800 feet. After 12
hours, he is at an altitude of 1400 feet. What is the average rate of change? *

Answers

Answer:

First Problem: 200 ft/hour Second Problem: 3 ft/hour

Step-by-step explanation:

R = D/T

So, 800/4=200

We will check if the rate matches for the second example rate:

1400/12=200. It does, so we know we are correct

Problem 2:

R = D/T

90/30=3

The answer is 34.6, or A.

Step-by-step explanation:

The formula for area is pi*r*r. This means that you will have to take the area, or A, and do this: [tex]\sqrt{\frac{a}{pi} }[/tex]. That would be that radius, so then multiply that by 2*pi, and that would give an answer of approximately 34.6.

Answers

Answer:

22.2m

Step-by-step explanation:

vol of a sphere = 4/3 x pi x r^3

vol of a hemisphere is 1/2 the vol of a sphere, so vol of a hemisphere= 2/3 x pi x r^3

2/3pi x r^3 = 257

Divide both sides by 2/3pi

r^3 = 122.708

Cube root both sides.

r = 11.077

Diameter is twice the radius, so diameter = 22.154m

To the nearest 10th of a meter this is 22.2m.

if the perimeter of a rectangle is 26x^2+16x+10 and the length is 8x^2+6x+4, what is the width?

Answers

Here is the set up:

P = 2L + 2W

P = 2(26x^2+16x+10) + 2(8x^2+6x+4)

Simplify the right side to find P.

Answer:

5x^2 + 14x + 9

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Find the surface area

Answers

363 inch²

Step-by-step explanation:

Each vertical face is a rectangle.

Area of each face = length x breadth

= 8 x 6 inch² = 48 inch²

There are 5 such faces, total area = 5 tiimes of 48 inch² = 240 inch²

For horizontal faces:

Observe: you can actually divide that face in 5 right-angled triangle(two edge point & centre form right angled ∆). With base 6 inch & height 4.1 inch.

For 2 such faces, you have 2 x 5 times of area of 1 ∆.

Area of 10∆s = 10 ( ½ x 4.1 x 6) = 123 inch²

Total area = area of horizontal surfaces + area of vertical surfaces

Total area = 240 + 123 inch² = 363 inch²
