Answer:
1) xₙ = n² - (n - 1)
2) 1/4
Step-by-step explanation:
1) 1 = 1² - (1-1)
3 = 2² - (2-1)
7 = 3² - (3-1)
13 = 4² - (4-1)
...........
xₙ = n² - (n - 1)
2) three consecutive terms of an exponential sequence: x, rx , r²x
x: 2nd term of linear sequence
rx: 6th term of linear sequence rx = x + 4d
r²x: 7th term of linear sequence r²x = rx + d d = r²x - rx
rx = x + 4 * (r²x - rx) = x + 4r²x - 4rx
4xr² -5rx + x = 0
x(4r² -5r + 1) = 0
x (4r - 1) ( r - 1) = 0
x = 0 or r = 1/4 or r = 1
if either x = 0 or r = 1 d will be equals to "0" everything became 0
So the only reasonable answer is r = 1/4
Answer:
<em>never </em>because they are continually increasing at the same rate without multiplying and dividing
Alright, so let's go through each choice.
First off, a checking account is an account at a bank against which checks can be drawn by the account depositor. Or basically, where you can write checks to others.
First answer:
Most checking accounts pay interest on deposits.<span>
</span>True, most banks tend to pay interest on deposits. However, <span>some banks will require that you use direct deposit or maintain a minimum balance. </span>Interest-bearing checking<span>: With an </span>interest<span>-bearing </span>checking account<span>, you are </span>paid interest<span> on the money in your </span>account<span>.</span>
B. When you write a check the bank takes money from your account and pays it to the person who submits the check.
True, this should be a no-brainer. You're paying the person with a check.
C. The bank keeps track of how much money you have left in your account and sends you a statement each month. A charge is usually made for this service
True, this is with almost every bank account.
So, this should be all of the above.
Answer:
The measure of angle A is 53 degrees
The measure of angle B is 37 degrees
Step-by-step explanation:
Here in this question, we are interested in calculating the measure of the two angle.
When how angles are complementary, it means the sum of both equals 90 degrees
mathematically ;
(7x + 4) + (4x + 9) = 90
7x + 4x + 4 + 9 = 90
11x + 13 = 90
11x = 90-13
11x = 77
x = 77/11 = 7
The measure of angle A = 7x + 4 = 7(7) + 4 = 49 + 4 = 53 degrees
The measure of B = 4x + 9 = 4(7) + 9 = 28 + 9 = 37 degrees
Answer:
The correct answer will be "0.756596 m²".
Step-by-step explanation:
The given values are:
The radius of an umbrella,
r = 0.4 m
The height of an umbrella,
h = 0.45 m
As we know,
The lateral surface of an umbrella will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
So that the amount of fabric needed will be "0.756596 m²".
