Answer:

After 18 years, Zach's account balance will be $ 6,614.66.

Step-by-step explanation:

Given that Zach's parents put $ 1,500 in her bank account for college tuition at an interest rate of 8.25% compounded weekly, to determine what will be the balance after 18 years the following calculation must be performed:

1,500 x (1 + 0.0825 / 52) ^ 18x52 = X

1,500 x 1.00158653 ^ 936 = X

6,614.66 = X

Therefore, after 18 years, Zach's account balance will be $ 6,614.66.

If Neil Works 3/4 of an hour on Monday and 6/10 of an hour on Tuesday how much time will she work altogether?
jek_recluse [69]

Answer:

C

Step-by-step explanation:

3/4 + 6/10

Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount

(3/4 * 5/5) + (6/10 * 2/2)=

15/20 + 12/20

Then add

15/20 + 12/20= 27/20

Then finally convert to mixed number

27/20 = 1 7/20

Use the discriminant to describe the roots of each equation. Then select the best description. 2m2 + 3 = m.
Tpy6a [65]

The roots of the equation , 2m^{2}+3=m, are non real roots.

<h3>Discriminants are what?</h3>

The quadratic formula's discriminant is represented by the square root symbol b^{2}-4ac. If there are two solutions, one solution, or none at all, the discriminant informs us.

As of now, 2m²+3=m we need to find the kind of roots they have.

2m²+3=m

2m²-m+3=0

Here, we can derive the following values from the equation:

a = 2, b = -1, c = 3

An equation's discriminant is stated as:

D = b²-4ac

D = (-1)(-1) - 4(2)(3)

D = 1 - 24

D = -23

Discriminant can determine the kind of roots that the equation contains.

In this instance, the discriminant is below 0.

The equation's roots are complex conjugates when D < 0.

Hence the roots for the equation are non real roots.
