Answer:

The Choices A and B have a Interest amount greater than $800, where;

A's Interest = $840

B's Interest = $810

Step-by-step explanation:

A. $2,000.00 at 6% for 7 years.

Interest = Principal x Time x Interest Rate

Interest = $2,000 x 7 x 0.06

Interest = $840

B. $4,500.00 at 3% for 6 years.

Interest = Principal x Time x Interest Rate

Interest = $4,500 x 6 x 0.03

Interest = $810

C. $1,400.00 at 6% for 9 years.

Interest = Principal x Time x Interest Rate

Interest = $1,400 x 9 x 0.06

Interest = $756

D. $800.00 at 15% for 5 years.​

Interest = Principal x Time x Interest Rate

Interest = $800 x 5 x 0.15

Interest = $600

Find <br> 6<br> 2<br> (<br> 9<br> )<br> . Express your answer as a fraction in simplest form.
kotykmax [81]

Based on the expression given, when it is solved, as a fraction in its simplest form it would be 558/1.

<h3>What is the fraction in its simplest form?</h3>

The expression, 62(9) can be rewritten as:

= 62 x 9

This is because the brackets denote that the number within the brackets should be multiplied by the number outside the bracket.

The solution is:

= 62 x 9

= 558

As this is an integer, it means that it has a denominator of 1. The fraction in its simplest form is therefore:

= 558 / 1

Solve r = 1/2m^2p for p
hoa [83]
You just have to arrange the equation such that the p is the only term at the left hand side of the equation. Express it in terms of r and m. 

r = 1/2*m²*p
Divide both left and right hand side equations by 1/2*m²
p = r/(1/2 *m²)
Take the reciprocal of 1/2 and multiply it. The final answer is:
p = 2r/m²

A man on the fifth floor of a building shouts down to a person on the street. If the angle of elevation from the street to the m
AleksandrR [38]

Answer: 57 ft

Step-by-step explanation: Because drawing it up, we can make a right angled triangle with the right angle between the height of the man in the building and the distance out from the building of the man in the street, and the 35 degrees between the line connecting the man in the street with the man in the building, and the line out from the building of the man in the street. Then, tan of the 35 degree angle is = to opposite (40ft)/adjacent (to solve for). By cross multiplication, the A or adjacent (dist out from the building) = 40/0.7 (0.7 = tan of 35 degrees) so the answer is 57 ft.

Answer:

-1/8

Step-by-step explanation:

lim x approaches -6     (sqrt( 10-x) -4) / (x+6)

Rationalize

   (sqrt( 10-x) -4)      (sqrt( 10-x) +4)

    ------------------- * -------------------

       (x+6)                 (sqrt( 10-x) +4)

We know ( a-b) (a+b) = a^2 -b^2

a= ( sqrt(10-x)   b = 4    

(10-x) -16

-------------------

(x+6) (sqrt( 10-x) +4)    

-6-x

-------------------

(x+6) (sqrt( 10-x) +4)

Factor out -1 from the numerator

-1( x+6)

-------------------

(x+6) (sqrt( 10-x) +4)

Cancel x+6 from the numerator and denominator

-1

-------------------

(sqrt( 10-x) +4)

Now take the limit

lim x approaches -6    -1/ (sqrt( 10-x) +4)

                                      -1/ (sqrt( 10- -6) +4)

                                      -1/ (sqrt(16) +4)

                                      -1 /( 4+4)

                                        -1/8
