Natalie earned $200 in interest and 30 months with a beginning balance of $1040. What was her interest rate?

rjkz [21]

The interest rate is 7.69%

Step-by-step explanation:

Given

Interest = $200

Time = t = 30 months

Time will be converted into years as the rate is applied yearly

So,

1 year = 12 months

30 months = 30/12 years = 2.5 years

Principal amount = $1040

The formula for interest is:

$I = P*r*t$

Putting the values

$200 = 1040 * r * 2.5\\200 = 2600r\\r = \frac{200}{2600}\\r = 0.076923$

Converting into percentage:

r = 7.6923

Rounding off to nearest hundredth

r = 7.69%

Hence,

The interest rate is 7.69%

For the following function, one zero is given. Find all other zeros.<br><br> f(x)=x3-7x2+17x-15; 2-i

ratelena [41]

Answer:

1,-3,-5

Step-by-step explanation:

Given:

f(x)=x^3+7x^2+7x-15

Finding all the possible rational zeros of f(x)

p= ±1,±3,±5,±15 (factors of coefficient of last term)

q=±1(factors of coefficient of leading term)

p/q=±1,±3,±5,±15

Now finding the rational zeros using rational root theorem

f(p/q)

f(1)=1+7+7-15

f(-1)= -1 +7-7-15

= -16

f(3)=27+7(9)+21-15

=96

f(-3)= (-3)^3+7(-3)^2+7(-3)-15

= 0

f(5)=5^3+7(5)^2+7(5)-15

=320

f(-5)=(-5)^3+7(-5)^2+7(-5)-15

f(15)=(15)^3+7(15)^2+7(15)-15

=5040

f(-15)=(-15)^3+7(-15)^2+7(-15)-15

=-1920

Hence the rational roots are 1,-3,-5 !
