Based on the amount deposited by Berno and the annual interest on the account, the amount in the account after fifteen years is $49,012.91.

The interest is said to compound quarterly which means that the periodic interest rate is:

= 3.25% / 4

= 0.8125%

The number of periods is:
= 15 x 4

= 60 quarters

The amount in the account after 15 years is:

= 30,000 x (1 + rate) ^ number of periods

= 30,000 x (1 + 0.8215%)⁶⁰

= $49,012.91

In conclusion, the amount in the account after 15 years would be $49,012.91.

Answer:

3x² + 24x + 36 = 0

Step-by-step explanation:

A quadratic equation has the standard form ax² + bx + c = 0.
a, b and c are constants.

The roots of a quadratic equation represent the two solutions to the quadratic equation

Given that the roots are -2 and -6 we have

x = -2 and x = -6 as the solutions

Add 2 to both sides of x = -2 ==> x + 2 = 0
Add 6 to both sides of x = -6 ==> x + 6= 0

So (x+2)(x+6) = 0 is the factored representation of this equation. We have to multiply by a leading coefficient of 3

So the quadratic equation is
3(x+2)(x+6) = 0

Using the FOIL method
(x + 2)(x + 6) = x² + 6x + 2x + 12 = x² + 8x + 12

The leading coefficient is the coefficient of x² and is given as 3

So the quadratic equation in standard form is
3(x² + 8x + 12) = 0

==>  3x² + 24x + 36 = 0

If you solve this equation on a quadratic equation calculator you will get the solutions x = -2 and x=-6

We get that, the amount that Karen can withdraw after 7 years will be $ 17376.98 compounded semi annually with interest rate of 3.32 %.

We are given that:

Principal amount = $ 11,000

Interest rate = 3.32 % compounded semi annually.

Time period = 7 years

t = 7 × 2 = 14 times

Amount = 11,000 ( 1 + 3.32 / 100 )¹⁴

Amount = 11,000 (1.0332)¹⁴

Amount = 11,000 ( 1.57973)

Amount = 17376.98

The amount will become = $ 17376.98 that Karen will withdrew for the down payment on a new house.

Therefore, we get that, the amount that Karen can withdraw after 7 years will be $ 17376.98 compounded semi annually with interest rate of 3.32 %.

Using proportions, it is found that the inflation rate was of 5.7%.

The inputs to the table will be given as follows:

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The inflation rate is found by the proportion of the 2016 CPI to the 2014 CPI, hence:

185/175 - 1 = 1.057 - 1 = 0.057.

The inflation rate was of 5.7%.

To find the amounts that complete each table, we have to find the 2014 table, and multiply the amounts by 1.057, hence:

Step-by-step explanation:

remember : to convert a fraction of one denominator into a fraction of another denominator, we need to multiply both (numerator and denominator) by the same factor, so that the denominator changes to the desired number, and the overall value of the fraction remains unchanged.

4 1/3 - 8

first I convert the mixed number into a full fraction :

4 1/3 = (4×3 + 1)/3 = 13/3

then, to be able to subtract 8, I need to convert 8 into a fraction with the same denominator as 13/3 :

8 = (8×3)/3 = 24/3

so, now I can do the subtraction :

13/3 - 24/3 = -11/3

-11/3 = -3 remainder 2 = -(3×3 + 2)/3 = -3 2/3

5 2/5 - (-2 4/15)

again, we convert all mixed numbers into full fractions :

5 2/5 = (5×5 + 2)/5 = 27/5

2 4/15 = (2×15 + 4)/15 = 34/15

now we need to bring both to the same denominator, and because 5 is a factor or 15, we can bring both to fractions of 1/15, for which we only need to transform the first fraction :

27/5 = 27/5 × 3/3 = 81/15

so, the subtraction is actually

81/15 - (-34/15) = 81/15 + 34/15 = 115/15 = 23/3

23/3 = 7 remainder 2 = (7×3 +2)/3 = 7 2/3

If Ian wants to get an expected quiz score of 83, then he needs to spend 3.33 hours in homework that week.

We know that the situation is modeled by the linear equation:

y = 60+ 6.9x

Where y represents the expected quiz score and x the hours spend on homework that week.

If we define y = 83, the value of x will be the number of hours that the students need to do homework such tath the expected quiz score is 83.

Solving the linear equation:

83 = 60 + 6.9*x

(83 - 60)/6.9 = x

23/6.9 = x

3.33 = x

So to get an expected quiz score of 83, they need to spend 3.33 hours in homework that week.

For the given right triangle, the tangent of theta is equal to 4/3 so the correct option is D.

Here we have a right triangle, and we want to find the tangent of one shown angle.

Remember that the trigonometric relation for a tangent is:

tan(a) =(opposite cathetus)/(adjacent cathetus).

On the image, we can see that the adjacent cathetus to the given angle has a measure of 6 units, while the opposite cathetus has a measure of 8 units, then we can replace that in the general relation to write:

tan(θ) = 8/6

Now we just can simplify that fraction if we divide both numerator and denominator by 2, we will get:

tan(θ) = 8/6 = 4/3

Then we conclude that the correct option is D.

UST+22x+3=UST+6x+4+79 ==> they both equal 180

22x+3=6x+4+79 ==> subtract UST on both sides

22x+3=6x+83

22x+3-3=6x+83-3

The line in standard notation is 2y - 7x = 7 and in slope-intercept form it is:

y = (7/2)*x + 7/2

We want our line to be perpendicular to 2x + 7y = 1

Rewriting that line, we get:

y = (1 - 2x)/7 = 1/7 - (2/7)*x

So the slope is (-2/7), then the slope of a perpendicular line is 7/2.

So our equation is something like:

y = (7/2)*x + b

To find the value of b we replace the values of the point (1, 7), it gives:

7 = (7/2)*1 + b

7 = 7/2 + b

7 - 7/2 = b

7/2 = b

Then the linear equation in slope-intercept is:

y = (7/2)*x + 7/2

And the standard form is:

y - (7/2)*x = 7/2

2y - 7x = 7

a is smaller than b, as shown by the symbol a<b.

When the expression a > b is employed, it means that an is larger than b.

In no circumstance is a the same as b. These relationships are referred to as strict inequalities since a is strictly less than or strictly greater than b. Equivalence isn't taken into account.
