If an=5n-3 find the common difference

elena55 [62]

Answer:

Hi here is your answer

an=5n-3

an-1= -3+5n

an-1= -3+5(n-1)

an-1= -3+5n-5

an-1= 5n-7

d= an- an-1

d=(5n-3)-(5n-7)

d=5n-3-5n+7

d=4

Answer: d = 4

Hope this helps you.

Given the function k(t)=2t−1: a. Evaluate k(2). b. Solve(k)=7.

Aleksandr-060686 [28]

Answer:

$k(2) = 3$

$t = 4$

Step-by-step explanation:

Given

$k(t) = 2t - 1$

Solving (1): k(2)

Take t as 2 such that t = 2

This gives

$k(2) = 2 * 2 - 1$

$k(2) = 4 - 1$

$k(2) = 3$

Solving (2): k(t) = 7

Substitute 7 for k(t)

$7 = 2t - 1$

Add 1 to both sides

$7 + 1 = 2t - 1 + 1$

$2t = 8$

Divide both sides by 2

$t = \frac{8}{2}$

$t = 4$

B. 25 Km. The measure of BC is 25 km.

The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.

BC = √AC²+AB²-2(AC)(AB)*cos A

BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°

BC = √441km²+196km²-588km²*(0.017)

BC =√637km²-10.26km²

BC = √636.74km²

BC = 25.03km ≅ 25
