Application Of A Cubic. Please Help!

Answers

Answer 1

Answer:

a. 28.

b 20.78.

Step-by-step explanation:

a. f(x) = 0.001(x -  10)(x + 20)(x - 40)

When x = 50

Height = f(40) = 0.001(50-10)(50+20)(50-40)

= 0.001(40*70*10)

= 0.001 * 28,000

= 28 units.

b.

Expanding the function we get

f(x) = 0.001(x  - 10)(x^2 - 20x - 800)

f(x) = 0.001(x^3 - 30x^2 - 600x + 8000)

f(x) = 0.001x^3 - 0.03x^2 - 0.6x + 8

Finding the derivative

f'(x) = 0.003x^2 - 0.06x - 0.6

This is zero for maxm/minm values:

0.003x^2 - 0.06x - 0.6 = 0

x = 27.32, - 7.32.

The values of the heights corresponding to these values of x are:

0.001(27.32-10)(27.32+20)(27.32-40)

= -10.39. and

0.001(-7.32-10)(-7.32+20)(-7.32-40)

= 10.39.

So the distance between A and B =  10.39 - (-10.39)

= 20.78.

Convert 310 to base 8.

Answers

Answer:

\(\Huge \boxed {\bf{466_8} }\)

Step-by-step explanation:

To convert the decimal number 310 to base 8, we can use the following steps:

Step 1: Divide the decimal number by the base (8) and obtain the quotient and remainder.

Step 2: Write down the remainder.

Step 3: Repeat the process with the quotient obtained in the previous step until the quotient is zero.

Step 4: Write down the remainders in reverse order.

Let's perform these steps for the decimal number 310:

310 ÷ 8 = 38 (remainder 6)38 ÷ 8 = 4 (remainder 6)4 ÷ 8 = 0 (remainder 4)

Now, write down the remainders in reverse order: 466.

So, the decimal number 310 converted to base 8 is \(466_8\).

22 and 15

Answers

Answer:

| a - b | < length of third side < a + b

Step-by-step explanation:

Visualize the two given sides of the triangle (let's call then a and b), joined at the vertex of the triangle, and forming an angle. We can join the other free end of these two segments, with another segment whose length would vary according to how tiny or large the angle is. We can spread the aperture of the angle they form as much as we can just below  (not reaching this angle measure, because in such case, there will be no triangle of tangible area. In such case, the length of the joining segment will be limited by the addition of the two sides:

length of third side < a + b

In the case the aperture of the angle formed by the two given sides is diminished as much as possible to still form a measurable triangle, the angle has to be just larger than zero, and in such case, the segment joining the other to ends of a and b would be just larger than the absolute value of the difference between a and b:

length third side > | a - b|

These are the two extreme cases, and the length of the third side must be within these limits.

Q1. If ∛5x+10=5, Find x

Answers

Answer: x=-25

Step-by-step explanation:

Concept to know:

When given a number that is cubic root, in order to solve the equation/function, you need to cube numbers on both sides.

Solve:

Given

∛5x+10=5

Subtract 10 on both sides

∛5x+10-10=5-10

∛5x=-5

Cube numbers on both sides

5x=-125

x=-25

Answer:

x = -25

Step-by-step explanation:

If ∛5x+10=5, Find x

∛5x = 5 - 10

∛5x = -5

take both sides of equation to the power of 3

5x = -125

x = -125/5

x = -25

Answer:

Option D. 39 is correct answer

Step-by-step explanation:

In this question we are given an expression that is + + x and value of x is equal to 3 . And we are asked to find the value of expression when value of x is 3 .

Solution : -

\( \quad \dashrightarrow \qquad \: x {}^{3} + x {}^{2} + x\)

Now substituting value of x as 3 in it ,

\( \quad \dashrightarrow \qquad \: 3 {}^{3} + 3 {}^{2} + 3\)

\( \quad \dashrightarrow \qquad \: 27 + 9 + 3\)

\( \quad \dashrightarrow \qquad \: 36 + 3\)

\( \quad \dashrightarrow \qquad \: \blue{\underline{\boxed{\frak{39}}}} \quad \bigstar\)

Henceforth , value of expression when x is equal to 3 is 39 .Therefore , Option D is correct.

Hey mate ,

The equation given is ++x

It has asked what would be the value of equation if we substitute 3 as the value of x

There are many ways to solve the equation ,

Lets use the simple one ,

When we substitute 3 at the place of x , we get

= x³+x²+x

= 3³ + 3² + 3

= 27 + 9 + 3

= 39

When we substitute 3 at the place of x we get 39

Answer:

The answer is C

Step-by-step explanation: When your doing something like this, it's best to be practical and pay attention to the wording

A says 16 pieces of candy shared with 6 friends which is 16/6 which can't be represented by 3/8

B would be represented by 8/3 due to it's wording and the order of which the words are

However C would be 3/8 since the words say, a 3 day trips divided into 8 segments which is 3/8 unlike B which said an 8-foot piece of wood cut into 3 pieces which would be 8/3

D is just 3x8 since he consistanly saves 3 dollars for 8 weeks

What is the surface area of a right triangular prism?

A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.

here, we have,

The surface area of a right triangular prism

= (Perimeter of the base × Length of the prism) + (2 × Base Area)

Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm

Actual base = 16 cm × 0.2 ft/cm = 3.2 ft

convert the units

9 cm = 9 cm × 0.2 ft/cm = 1.8 ft

10 cm = 10 cm × 0.2 ft/cm = 2 ft

The surface area of a right triangular prism

= (Perimeter of the base × Length of the prism) + (2 × Base Area)

Surface area of actual ramp

= 2(0.5 × 3.2 ft × 1.2 ft) + 2(2 ft × 1.8 ft) + (1.8 ft × 3.2 ft)

= 16.8 ft²

Hence, the surface area of the actual ramp including the underside is 16.8 ft²

We don't know how many cars James has but we know they have 't'. But we know Paul has 13 cars. The question asks if Paul hands over half of his cars to James how many would James have? Well, 13 / 2 = 6.5

If James right now has 't' cars then after Pauls give his cars, then James will have t + 6.5.

Hope this helps!

Explanation:
No. of toy cars with James= t
No. of toy cars with Paul= t+13
Therefore, No. of cars James will have if Paul will give him half of his toy cars:
t+t+13*1/2
=(2t+13)/2
=t+6.5

Answer: James will have (t+6.5) toy cars in all.

Answer:

The arithmetic sequence expression for the given sequence 6, 9, 12, 15, 18....... would be aₙ = 6+(n-1)3.

What is an arithmetic sequence?

A progression or sequence of numbers known as an arithmetic sequence maintains a consistent difference between each succeeding term and its predecessor.

The common difference of that mathematical progression is the constant difference.

'n' denotes the term's position in the supplied arithmetic sequence in the formula for obtaining the general term: a = a1 + (n - 1) d. For instance, a2 denotes the second phrase in the sequence.

So, the given sequence is:

6, 9, 12, 15, 18

Common difference (d) is: 9 - 6 = 3

Then, the sequence expression would be:

aₙ = 6+(n-1)3

Therefore, the arithmetic sequence expression for the given sequence 6, 9, 12, 15, 18....... would be aₙ = 6+(n-1)3.

Answers

Answer: 12 degrees or 11 5/5 or 60/5

Step-by-step explanation:

Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.

For the number line you just have to find 1/5 and 2 2/5 on it and mark it.
