The first three terms of an arithmetic sequence are 3k-1, 4k+1, 6k-2. What is the value of k?​
yawa3891 [41]

Answer:

k = 5

Step-by-step explanation:

First three terms of an AP are 3k-1, 4k+1, 6k-2.

First term is 3k-1

For an AP,

a₂-a₁=a₃-a₂

4k+1-(3k-1)=6k-2-(4k+1)

4k+1-3k+1=6k-2-4k-1

k+2=2k-3

Separating like terms,

k-2k=-3-2

-k=-5

k = 5

So, the value of k is 5.

Peter invests $525 at a simple interest rate of 4%. How much interest will he earn after 6 years?
Anna71 [15]
He will earn $126 in interest.
How did I solve this:
Find the decimal of 4%:
4% = 0.04
Multiply 0.04 times 525:
0.04 x 525 = 21
Multiply $21 times 6 years:
21 x 6 = 126
126 is your correct and finale answer.
Hope this helps! =)

Given that sin(x)=7/11, find cos(90-x). A. 4/11 B. 7/11 C. 11/7 D. 11/4
Contact [7]
Based on the given equation above, get the value of x first so that this value can be substituted to the second equation. Value of x can be obtained by taking the arc sin of 7/11 which gives an answer of 39.52 degrees. Substituting this value to the second equation cos (90-39.52) gives an answer equals to 7/11

The perimeter of a rectangular field is 340 yards. The length is 90 yd longer than the width. Find the dimensions.
Alexus [3.1K]

Answer:

length= 100 width=70

Step-by-step explanation:

The perimeter of a rectangular field is 340 yds.  

The length is 30 yds longer than the width.  

2(l + w) = 340

l + w = 170

w + 30 + w = 170

2w = 140

w = 70

Hence the dimensions:

Length: 100 yds.

Width: 70 yds.
