Answer:

36π - 72 sq in.

Step-by-step explanation:

π×12² = 144π

90/360 × 144π = 36π

Triangle = ½ × 12 × 12 = 72

Segment = 36π - 72

Write a formula that will yield the nth term of the sequence: 3,-2,-7,-12
RUDIKE [14]

Answer:

-5n + 8

Step-by-step explanation:

<u>1. What is the difference?</u>

  The sequence goes down by 5. This means that the formula will have -5n in it.

<u>2. Work out the term before the first term.</u>

    The first term is 3, and we know that the sequence goes up by 5. So, to get the term before 3 we would add 5.

3 + 5 = 8   Remember, this is positive 8. (+8)

<u>3. Put that term at the end of the equation. </u>

   We have -5n already and we just worked out the term before the first one which is positive 8 - so put that at the end of the equation.

-5n + 8  This is our answer!

Just to prove it works:

<em>Substitute:   n = term</em>

Lets see if we can get the 3rd term which is -7. (n = 3)

-5(3) + 8

-15 + 8 = -7

See, it works!

Answer:

AB = square root of 403

Step-by-step explanation:

use the pythagorean theorem to solve for AB.

a^2 + b^2 = c^2

9^2 + b^2 = 22^2

81 + b^2 = 484

b^2 = 484 - 81

b^2 = 403

b = 20.07

Michael started a savings account with $100. After 6 weeks, he had $140, and after 12 weeks, he had $260. What is the rate of ch
ale4655 [162]

Answer:

Rate of change of money in Michael's account will be $20 per week.

Step-by-step explanation:

If we draw a graph for the duration of investment on x-axis and amount in the account on y-axis, ordered pairs for both the conditions will be,

After 6 weeks, amount in the account = $140

Ordered pair : (6, 140)

After 12 weeks, amount in the account = $260

Ordered pair : (12, 260)

Rate of change in hi account per week = \frac{\triangle y}{\triangle x}

                                                                 = \frac{260-140}{12-6}

                                                                 = \frac{120}{6}

                                                                 = $20 per week

Therefore, rate of change of money in Michael's account will be $20 per week.
