Mathematics, I want the answer only.

Answer:

d=1

e=4/9

f=16/81

Step-by-step explanation:

Substitute x in the right column with the values in the left column to find d, e, and f.

Answer:

d = 1

e = 4/9

f = 16/81

Step-by-step explanation:

d is 1 because any term raised to the power of zero equals one

e: (2/3)² = 2²/3² = 4/9

f: (2/3)^4 = 2^4/3^4 = 16/81

Answer:

first one

just subtract 21 from each number

Answer:

C - {873, 894, 915, 936, …}

Step-by-step explanation:

Difference means subtraction. So, subtract -21 from the number to get your next value.

1245 - (-21) = 1266 So, A is not the answer

32 - (-21) = 53 So, B is not the answer.

873 - (-21) = 894 So, C is the answer.

1563 - (-21) = 1584 So, D is not the answer.

To double check, subtract -21 from the other numbers too.

873 - (-21) = 894

894 - (-21) = 915

915 - (-21) = 936

and so on...

This matches up with the list of numbers on option C so it it correct.

I hope this helps you Cheers!

Answer:

nth term = 1000×1.2ⁿ⁻¹

Step-by-step explanation:

The explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant.

Given that, in two years the deer population in a state forest was 1,200. In year 4, the population was 1,728,

Therefore,

a₄ = 1728 and a₂ = 1200

We have two terms of the GP, therefore, finding r,

r² = 1728 / 1200 = 1.44

r = 1.2

Therefore,

a₁ = a₂r¹⁻²

= 1200r⁻¹ = 1200/r

= 1200 / 1.2 = 1000

Therefore, the formula will be = aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

Hence, the explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

Answer:

Step-by-step explanation:

W = 4L-17

LW = 15

L(4L-17) = 15

4L^2-17L-15= 0

L = [17 ±√(17^2-4(4)(-15))]/[2(4)] = 5,-3/4

B. Invesment

Correct me if You want If its wrong.

Answer:

1. Assume the contrary, namely that √2 + √3 + √5 = r, where r is a rational number.

Square the equality √2 + √3 = r − √5 to obtain 5 + 2

√6 = r2 + 5 − 2r

√5. It follows

that 2√6 + 2r

√5 is itself rational. Squaring again, we find that 24 + 20r2 + 8r

√30

is rational, and hence √30 is rational, too. Pythagoras’ method for proving that √2 is

irrational can now be applied to show that this is not true. Write √30 = m

n in lowest

terms; then transform this into m2 = 30n2. It follows that m is divisible by 2 and because

2( m

2 )2 = 15n2 it follows that n is divisible by 2 as well. So the fraction was not in lowest

terms, a contradiction. We conclude that the initial assumption was false, and therefore

√2 + √3 + √5 is irrational.

Answer:

  d)  3195

Step-by-step explanation:

The distances traveled make an arithmetic series, the sum of which is given by ...

  Sn = (2·a1 +d(n -1))(n/2)

This series has first term a1=5 and common difference d=7. Then the total distance traveled in 30 seconds is ...

  S30 = (2·5 +7(30-1))(30/2) = (10 +203)(15) = 3195

The cart travels 3195 inches.

Answer:

Step-by-step explanation:

"The difference of two numbers is 15."

x-y = 15

x>y

"Five times the smaller number is the same as 9 less than twice the larger number."

5y = 2x-9

y = x-15

substitution

5(x-15) = 2x-9

5x-75 = 2x-9

3x = 66

x = 22

y = x-15 = 7
