find 8th and 10th of G.P whose first term and common ratio are 6 and 2 respectively​

Answers

Answer:

a₈ = 768 , a₁₀ = 3072

Step-by-step explanation:

The nth term of a GP is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 6 and r = 2 , then

a₈ = 6 × [tex]2^{7}[/tex] = 6 × 128 = 768

a₁₀ = 6 × [tex]2^{9}[/tex] = 6 × 512 = 3072

Answer:

  1/x = (1+√5)/2 ≈ 1.618034

Step-by-step explanation:

Since you are only interested in the second part, we presume you have solved the quadratic equation to find ...

  x = (√5 -1)/2 ≈ 0.618034

The second part asks for 1/x. The usual method for rationalizing the denominator will be useful for this. Multiply numerator and denominator by the conjugate of the denominator.

  [tex]\dfrac{1}{x}=1\div\dfrac{\sqrt{5}-1}{2}=1\times\dfrac{2}{\sqrt{5}-1}\\\\=\dfrac{2(\sqrt{5}+1)}{(\sqrt{5}-1)(\sqrt{5}+1)}=\dfrac{2\sqrt{5}+2}{5-1}=\boxed{\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

Solve the inequality, write the answer in interval notation.

Answers

9514 1404 393

Answer:

  (-∞, 2-√7) ∪ (2+√7, ∞)

Step-by-step explanation:

The factored form of a polynomial is helpful for solving related inequalities. For quadratics with two real zeros, the sign changes at each zero. If the leading coefficient is positive, the sign is positive to for x-values "outside" either zero, and is negative between the zeros.

Your inequality can be written in standard form as ...

  x² -4x -3 > 0

  x² -4x +4 -7 > 0

  (x -2 -√7)(x -2 +√7) > 0 . . . . . factor the difference of squares (x-2)² -7

The zeros are at x=2-√7 and x=2+√7, so the product of these factors will be positive for x < 2-√7 and x > 2+√7. The solution in interval notation is ...

  (-∞, 2-√7) ∪ (2+√7, ∞)

_____

Additional comment

We suspect a typo in the problem statement. If it were to read ... > -3, then the zeros would be at 1 and 3, and the solution would be (-∞, 1)∪(3, ∞).

How many ways can 100 be written as the sum of distinct integers from the set {1, 2,..., 15}?

Answers

Answer:

48 ways

Step-by-step explanation:

Let me take a guess

S₁_₁₅ = (1+15)*7 + 8 = 120

There are 48 combinations of distinct digits from 1 to 15 to make 20

120-20=100

So every 20 has a corresponding 100

Step-by-step explanation:

find the amount of Money raised

buy multiplying the amount raised per mile by each sponsor with the number of sponsor and the number of miles walked

[tex](30 \times 0.50) \times 25 = 375[/tex]

to find the remaining, subtract the raised amount from the intended amount.

A large cargo ship dropped anchor in the ocean. The anchor was released at a constant rate rate of speed from a height of 44 meters

Answers

Answer:

C and E

Step-by-step explanation:

The change in elevation was 44 + 20 = 64 m

the rate of fall was 64 m / 32 s = 2 m/s

The anchor reached the surface in 44 / 2 = 22 s so C is valid

E is correct as the ocean surface is origin and Up is the positive direction.

The anchor starts at 44 m above the surface and position is lower by 2 meters every second

From the question, the two correct options about the speed with which the anchor was released are:

Option COption E

How to solve for the solution

First we have to calculate the change that occurred in the elevation. Initially it was 44 meters but dropped 20 m below water.

44 + 20 = 64 meters

Next we calculate the rate with which the fall occurred

The time with which it fell was 32 seconds. = 64/32 = 2 meters pers second

44/2 = 22 hence it can be concluded that C is right.

Option E is also correct given that the water surface is above the ground and it is positive

Charlie ate ¾ cup dry food for breakfast and another ½ cup for dinner. If the food
has a caloric density of 360kcal/cup, how many kcal did Charlie eat in total? Please show work!

Answers

Answer: 450 kcal

Step-by-step explanation:

So you know the food is 360 kcal per 1 cup

by setting up a proportion, you can relate the number of kcal to cups.

[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(3/4 +1/2)cup} \\\\[/tex]

we can simplify the fraction to this:

[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(5/4)cup} \\\\[/tex]

by cross multiplying you can solve the proportion

(360) * (5/4) = (?) * (1)

simplifying gets this:

450 = ?

so he ate 450 kcal total

Joy has some pairs of shoes six pairs of them are sneakers what expression shows how many pairs of shoes joy has that are not sneakers

Answers

To find the number of shoes that are not sneakers, 1. Take the total amount of sneakers, 2. Subtract the amount of sneakers Joy does have. So basically the equation is: NONsneaker shoes = TOTAL shoes - sneakers. To make an actual equation, put the number 6 in the equation to represent the number of sneakers. Then use two DIFFERENT coefficients, one to represent nonsneaker shoes, and the other to represent total shoes. One example of what this equation can look like is… n = 6 - s

The speed of a bus weighing 2000 kg increases from 50 mls to 60 m/s in 4 s. Calculate the change in its momentum and the Force applied on it

Answers

Answer:

Momentum = 20 000 kgm/s

Force applied = 5000 N

Step-by-step explanation:

Momentum = Mass * Velocity

= 2000 kg * 10 m/s

= 20 000 kgm/s

Force = Mass * Acceleration

Acceleration = v - u / t

= 60-50/4

= 10/4

= 2.5 m/s^2

F = m*a

= 2000 * 2.5

= 5 000 N

0.04 with 4 repeating as a fraction. Not the 04 repeating just the 4 is repeating. What is the answer???

Answer:

2/45

Step-by-step explanation:

0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: [tex](\frac{1}{10} )(\frac{4}{9} )[/tex]. Multiplying the two fractions results in 4/90 which can be simplified to 2/45.
