Hello,

f(x)=x²-2x-15=x²-2x+1-16=(x-1)²-16
=(x-1-4)(x-1+4)=(x-5)(x+3)
Zeroes are x=5 or x=-3

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in
german

Answer:

year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $7000.00.

r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:

The interest is: $420.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 7000.00 + 420.00 = 7420.00. For example:

If you borrowed the $7000.00, you would now owe $7420.00

If you loaned someone $7000.00, you would now be due $7420.00

If owned something, like a $7000.00 bond, it would be worth $7420.00 now.

In Triangle A B C, what is the value of x? Triangle A B C. Angle A is (10 x minus 10) degrees, angle B is (8 x) degrees, angle C
Naily [24]

Answer:

x = 6.5

Step-by-step explanation:

Since all angles in a triangle adds up to 180°, we have:

10x - 10 + 10x + 8 + 8x = 180

28x - 2 = 180

28x = 182

x = 182/28 or 6.5
