Please Help!Three years ago, Jolene bought $875 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of
6 1/2%

per year. How much is the stock worth now? Round the answer to the nearest cent.

The stock is worth $_______now.

Answers

Answer 1
Answer: If you would like to know how much is the stock worth now, you can calculate this using the following steps:

1 year: 6 1/2 % of $875 = 6.5% * $875 = 6.5/100 * 875 = $56.875
$875 + $56.875 = $931.875
2 year: 6 1/2 % of $931.875 = 6.5% * $931.875 = 6.5/100 * 931.875 = $60.572
$931.875 + $60.572 = $992.447
3 year: 6 1/2 % of $992.447 = 6.5% * $992.447 = 6.5/100 * 992.447 = $64.509
$992.447 + $64.509 = $1056.956 = $1056.96 = $1057

The correct result would be: The stock is worth $1057 now.

If a baseball and a bat cost $1.10 together, and the bat costs $1.00 more than the ball, how much does the ball cost?

Answers

Contrary to the above answer, the ball does not cost $0.10! If the ball were to cost 0.10 then the bat must cost $1.00 which is only $0.90 more than the ball! We can solve this equation correctly using an expression like so:
b = price of the ball
b + 1 = price of the bat
b + (b + 1) = price of the ball + price of the bat
b + b + 1 = 1.10
Therefore reareanging the equation:
2b = 0.10
And therefore:
b = 0.05
So the ball costs $0.05 and the bat costs $1.05 :))

Step-by-step explanation:

2 sin^2 (x) -5 sin (x) -3=0 I. Rewrite the equation by substituting the expression u in for sin x.

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

III. Use the zero product property to solve the quadratic equation.

IV. Rewrite your solutions to Part III by replacing u with sin x.

V. Solve the remaining equations for x, giving all solutions to the equation.

Answers

we have that

2sin^(2) x-5sin x-3=0

I. Rewrite the equation by substituting the expression u in for sin x.

2u^(2) -5u-3=0

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

2u^(2) -5u-3=0 is equal to

using a graph calculator-----> see the attached figure

(u-3)*(2u+1)=0

III. Use the zero product property to solve the quadratic equation.

(u-3)*(2u+1)=0

(u-3)=0--------------> u=3

(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5

IV. Rewrite your solutions to Part III by replacing u with sin x.

sin x=3--------> is not the solution (sin x can not be greater than 1)

sin x=-0.50------>is the solution

V. Solve the remaining equations for x, giving all solutions to the equation.

sin x=-0.50

if the sine is negative

then

x belong to the III or IV quadrant

we know that

sin 30°=0.50

so

the solution for the III quadrant is

x=180°+30°-------> x=210°

the solution for the IV quadrant is

x=360°-30°------> x=330°

Which fraction shows the simplest form for 4/12 A.1/4 B.12 C.1/2 D.1/3

Answers

4/12 can both go into 4. 4 divided by 4 is obviously 1, so the numerator is 1.12 divided by 4 is 3 so the denominator  is 3.
The answer is 1/3 or D

48/52 is the probability. but you can't stop there, you need to reduce.
12/13 is the simplest form and so there is your probability. (divided by 4 to get it)
