Answer:

Step-by-step explanation:

Given the sequence 1.4,5.5,9.6,13.7,...

The nth term of am arithmetic sequence is expressed as;

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

From the given data;

a = 1.4

d = 5.5-1.4 = 9.6-5.5 = 4.1

n = 72 (since we are looking for the 72nd term)

Substitute;

T₇₂ = 1.4+(72-1)(4.1)

T₇₂ = 1.4+71(4.1)

T₇₂ = 1.4+291.1

T₇₂ = 292.5

Hence the 72nd term of the sequence is 292.5

Answer:

Nope

It's a exponent, x^2 means x*x so it's actually a function

Answer:

C. 66 mm (using 3.14, it would be 65.94 mm)

Step-by-step explanation:

From what I know, the radius of this coin is 10.5 mm.

The formula for the circumference of a circle is 2πr or πd.

In this case we're using 3.14 for π.

(2 * 10.5) * 3.14

21 * 3.14

21 * 3.14 is the same as 62.8 + 3.14

62.8 + 3.14

65.94 mm

This is close to 66 mm, which was C, so that is the answer.

Answer: 51/8

Step-by-step explanation:

Answer: 50%

Step-by-step explanation:

In 2010, there were only 2 bike manufacturers and they had market shares of 30% and 70%.

A new manufacturer joins the market and captures 10% of the market share and Splendor increases to 40% of market share.

Market shares:

Yamaha = 10%

Splendor = 40%

Passion = 100% - 10% - 40%

= 50%

We know the value of x. We just have to substitute 3 in x in the equation.

2(3) + 3

6 + 3

9

9 is your answer. I hope this helps! Let me know if you need more help!

Answer:

(A) ∫₁⁵[Xₙ + k] where n ranges from 1 to 5

(B) 73.6

Step-by-step explanation:

The question is clear enough. Kudos!

So there are many players but we're focusing on Ricky.

Ricky has already recorded his score for each of the 5 rounds in the tournament.

The number of strokes in Ricky's record are to be added to or subtracted from a given number 72

ROUND 1:    [72 - 5] strokes = 67

ROUND 2:   [72 + 6] strokes = 78

ROUND 3:   [72 - 2] strokes = 70

ROUND 4:   [72 + 4] strokes = 76

ROUND 5:   [72 + 5] strokes = 77

(A) Write an expression to represent Ricky's total number of strokes for the five rounds.

Do not panic at this first exercise. You are to write an expression which when evaluated, will give the total number of strokes for all five rounds!

You are already given an abstract number '72' to work with in this question.

It is a fixed quantity which influences the value of strokes for each round.

We will represent this by an algebra, if we have to create the above required expression.

The expression will then be:

∫₁⁵[Xₙ + k] where n ranges from 1 to 5

You already know that the sigma sign '∫' represents summation and that's summation from the subscript '1' to the superscript '5'.

X₁ would be -5,   X₂ would be +6,   X₃ would be -2,   X₄ would be +4,   X₅ would be +5

K is the constant 72

(B) What was Ricky's average number of strokes per round?

Out of the 5 rounds, the average number of strokes per round would be

[67 + 78 + 70 + 76 +77] ÷ 5

= 368/5  = 73.6

Answer:

There are 3,628,800 different ways for the runners to finish.

Step-by-step explanation:

Arrangments of x elements:

The number of possible arrangments of x elements is given by the following formula:

[tex]A_{x} = x![/tex]

In this question:

10 different runners, which means that the number of different ways that there are for the runners to finish is an arrangment of 10 elements. So

[tex]A_{10} = 10! = 3628800[/tex]

There are 3,628,800 different ways for the runners to finish.

Answer:

x=-2

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

−2x+6−6=10−6

−2x=4

Step 2: Divide both sides by -2.

−2x=4

Answer:

9%=15,000

7%=12,000

thats what i think.

Answer:

The amount of 12% note is $90,000

The amount of 9% note is $80,000

Step-by-step explanation:

Missing word "The amount of the 12% note is $ and the amount of the 9% note is $"

Selling price = $170,000

Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)

Given total annual interest = $18,000

Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)

18,000 = 0.12x + 0.09*(170000 - x)

18,000 = 0.12x + 15,300 - 0.09x

18,000 = 0.03x + 15,300

0.03x = 18,000 - 15,300

0.03x = 2,700

x = 2,700/0.03

x = 90,000

So, the amount of 12% note is $90,000

So long term paid money = $170,000 - $90,000 = $80,000

So, the amount of 9% note is $80,000

Answer:

its 12 :)

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

THE ANSWER IS 12

Step-by-step explanation:

First, S must be 4, as if S was 5 the sum would be a 4 digit number.

T+N should be greater than 10 as we want to find the maximum.

Similarly, A+U must be greater than 10, making O equal to 9

We know that A+U-10 = T+N if T+N is less than 10 -- if T+N is greater than 10, A+U-10 = T+N - 10

Writing a quick python script that's not the cleanest nor most concise, I have

import pandas as pd

sols = []

sols_combos = []

num_sols = 0

for a in range(0, 10):

   for u in range (0,10):

       for t in range(0,10):

           for n in range(0,10):

               if (len({a,u,t,n}) == 4) & (4 not in {a,u,t,n}) & (9 not in {a,u,t,n}):

                   if (a+u >= 10):

                       if (t+n >= 10):

                           if ((a+u-10) == (t+n-10)):

                               sols.append(a+u-10)

                               sols_combos.append([a,u,t,n])

                               num_sols += 1

                       else:

                           if ((a+u-10) == (t+n)):

                               sols.append(a+u-10)

                               sols_combos.append([a,u,t,n])

                               num_sols += 1

list_max = [i for i, x in enumerate(sols) if x == max(sols)]

pd.Series(sols_combos).loc[list_max]

as my script.

the maximum I get for F is 5, and the solutions, in terms of A, U, T, and N are as follows:

[7, 8, 0, 5]

[7, 8, 2, 3]

[7, 8, 3, 2]

[7, 8, 5, 0]

[8, 7, 0, 5]

[8, 7, 2, 3]

[8, 7, 3, 2]

[8, 7, 5, 0]

This means that F is 5

Answer:

x + y = 0

Step-by-step explanation:

x and y are both the same distance from 0 on the number line. That means they are additive inverses (or opposites). Knowing this law, additive inverses always equal 0.

Given

See attachment for triangles

Required

Determine the missing sides

All 4 triangles are right-angled. So, to calculate the missing sides, we apply Pythagoras theorem which states that:

[tex]Hyp^2 = Adj^2 + Opp^2[/tex]

Solving (1):

[tex]Hypotenuse = 13[/tex]

So, we have:

[tex]13^2 = 12^2 + x^2[/tex]

[tex]169 = 144 + x^2[/tex]

Make [tex]x^2[/tex] the subject

[tex]x^2 = 169 - 144[/tex]

[tex]x^2 = 25[/tex]

Take positive square root of both sides

[tex]x = \sqrt{25[/tex]

[tex]x = 5\ in[/tex]

Solving (2):

[tex]Hypotenuse = x[/tex]

So, we have:

[tex]x^2 = 4^2 + 3^2[/tex]

[tex]x^2 = 16 + 9[/tex]

[tex]x^2 = 25[/tex]

Take positive square root of both sides

[tex]x = \sqrt{25[/tex]

[tex]x = 5\ mi[/tex]

Solving (3):

[tex]Hypotenuse = 14.7[/tex]

So, we have:

[tex]14.7^2 = x^2 + 11.9^2[/tex]

[tex]216.09 = x^2 + 141.61[/tex]

Make [tex]x^2[/tex] the subject

[tex]x^2 = 216.09 - 141.61[/tex]

[tex]x^2 = 74.48[/tex]

Take positive square root of both sides

[tex]x = \sqrt{74.48[/tex]

[tex]x = 8.6\ km[/tex]

Solving (4):

[tex]Hypotenuse = 15.4[/tex]

So, we have:

[tex]15.4^2 = x^2 + 6.3^2[/tex]

[tex]237.16 = x^2 + 39.69[/tex]

Make [tex]x^2[/tex] the subject

[tex]x^2= 237.16 - 39.69[/tex]

[tex]x^2= 197.47[/tex]

Take positive square root of both sides

[tex]x= \sqrt{197.47[/tex]

[tex]x= 14.1\ mi[/tex]

Answer:

The volume of cone changing at rate [tex]\frac{400}{3}\pi in^3/s[/tex]

Step-by-step explanation:

Let r be the radius of cone and h be the height of cone

[tex]\frac{dr}{dt}=2 in/s[/tex]

[tex]\frac{dh}{dt}=-4 in/s[/tex]

We have to find the rate at which the volume of cone changing when r=10 in and h=20 in

Volume of cone

[tex]V=\frac{1}{3}\pi r^2 h[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=\frac{1}{3}\pi (2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]

Substitute the values

[tex]\frac{dV}{dt}=\frac{1}{3}\pi(2\times 10\times 20\times 2+(10)^2\times (-4))[/tex]

[tex]\frac{dV}{dt}=\frac{1}{3}\pi(400)=\frac{400}{3}\pi in^3/s[/tex]

Hence, the volume of cone changing at rate [tex]\frac{400}{3}\pi in^3/s[/tex]
