Answer:

a7 is 10.24

Step-by-step explanation:

The formula for determining the nth term of a geometric sequence is expressed as

Tn = ar^(n - 1)

Where

r represents the common ratio of the sequence.

a represents the first term of the sequence.

n represents the number if terms of the sequence.

We want to determine the 7th term of the geometric sequence, T7

From the information given,

a = 2500

r = 2/5

T7 = 2500 × 2/5^(7 - 1)

T7 = 2500 × 2/5^6

T7 = 2500 × 64/15625

T7 = 10.24

Answer:

<em>Answer is option d</em><em> </em>

<em>Answer is </em><em>given below with explanations</em><em>. </em>

Step-by-step explanation:

We can prove that the two triangles are similar.

We can prove this using AA criterion of similarity.

In triangle DNC and triangle QSC

Vertically opposite angles are equal.

Then Angle QCS = Angle DCN

Two parallel lines cut by a transversal line make the alternate angles are equal.

Then Angle NDC = Angle CQS

By AA criterion of similarity

TRIANGLE DNC ~ TRIANGLE QSC

masha68 [24]
Hello,

Using V = (pi)(r)^2(h) :
V = 12
r = ?
h = 8
12 = (pi)(r)^2(8)
12/(8pi) = r^2
sqrt(12/8pi) = sqrt(r^2)
r = .69 in

Good luck to you!

What is the answer to 5 1/2 - 2/3
aniked [119]

To solve this problem, we first have to convert 5 1/2 into an improper fraction. To do this, we multiply the unit (5) times the denominator (2) and then add the numerator (1) to the product, while still keeping the same denominator.


(5 * 2) + 1 = 10 + 1 = 11/2


Now, this makes our expression: 11/2 - 2/3


Next, we have to find a common denominator for 2 and 3 by finding their shared LCM, or least common multiple. In this case, the LCM is 6. This means that we are going to convert both of the fractions in the expression into fractions with the denominator 6, so that we can easily compute the subtraction.


11 * 3 / 2 * 3 - 2 * 2 / 3 * 2


33/6 - 4/6


Now, we can simply subtract the numerators to find our final answer.


29/6


Your final answer is 29/6.


Hope this helps!
