Answer:

$255.98.

Step-by-step explanation:

The original price is 199.99.

If the store raises the price by 13%, then we must simplify 13% into decimal form.

13% = 13/100 = .13.

199.99 x .13 = 25.99

If they raised the price by 13%, then we are adding the original price to the 13% they added.

199.99 + 25.99 = 225.98

The price after raised by 13% is $255.98.

if f(1) = -5 and f(n) = f(n-1) +7, find the first four terms and the common difference of the sequence
Alex_Xolod [135]

Answer:

- 5, 2, 9, 16 and d = + 7

Step-by-step explanation:

to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula

f(1) = - 5 ← given

f(2) = f(1) + 7 = - 5 + 7 = 2

f(3) = f(2) + 7 = 2 + 7 = 9

f(4) = f(3) + 7 = 9 + 7 = 16

common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7

10. Make q the subject of the formula 5(q + p) = 4 + 8p
vichka [17]

The formula subject to q is \frac{4+3p}{5}

Explanation:

The given formula is 5(q+p)=4+8 p

We need to determine the formula subject to q.

<u>The formula subject to q:</u>

The formula subject to q can be determined by solving the formula for q.

Let us solve the formula.

Thus, we have;

5q+5p=4+8p

Subtracting both sides by 5p, we have;

5q=4+3p

Dividing both sides by 5, we get;

q=\frac{4+3p}{5}

Thus, the formula subject to q is \frac{4+3p}{5}
