Answer:
sin B= square root of 3/ 2
Cos B= 1/2
tan B= square root of 3/1
Sin C=1/2
cos C square root of 3/2
tan C= 1/square root of 3
Step-by-step explanation:
Sophia and Skylar go to the movie theater and purchase refreshments for their friends.
1 answer:
3p + 7d = 98.75 and 15p + 6d = 218.25 are the system of equations that can be used to find the price of one bag of popcorn and the price of one drink
The price of 1 drink is $ 9.5
<em><u>Solution:</u></em>
Let "p" be the price of 1 bag of popcorn
Let "d" be the price of 1 drink
Given that,
<em><u>Sophia spends a total of $98.75 on 3 bags of popcorn and 7 drinks</u></em>
Therefore, we can frame a equation as,
3 x price of 1 bag of popcorn + 7 x price of 1 drink = 98.75
3p + 7d = 98.75 -------- eqn 1
<em><u>Skylar spends a total of $218.25 on 15 bags of popcorn and 6 drinks</u></em>
15 x price of 1 bag of popcorn + 6 x price of 1 drink = 218.25
15p + 6d = 218.25 -------- eqn 2
Thus eqn 1 and eqn 2 are the system of equations that can be used to find the price of one bag of popcorn and the price of one drink
<em><u>Determine and state the price of a drink:</u></em>
Let us solve eqn 1 and eqn 2
<em><u>Multiply eqn 1 by 5</u></em>
15p + 35d = 493.75 ------ eqn 3
<em><u>Subtract eqn 2 from eqn 3</u></em>
15p + 35d = 493.75
15p + 6d = 218.25
( - ) -------------------------------
29d = 275.5
d = 9.5
<em><u>Substitute d = 9.5 in eqn 1</u></em>
3p + 7(9.5) = 98.75
3p + 66.5 = 98.75
3p = 32.25
p = 10.75
Thus the price of 1 drink is $ 9.5

Step-by-step explanation:
In essence, one needs to work their way backwards to solve this problem. Use the information to construct the function.
The function has verticle asymptotes at (x = 4) and (x = 5). This means that the denominator must have (x - 4) and (x - 5) in it. This is because a verticle asymptote indicates that the function cannot have a value at these points, the function jumps at these points. This is because the denominator of a fraction cannot be (0), the values (x - 4) and (x - 5) ensure this. Since if (x) equals (4) or (5) in this situation, the denominator would be (0) because of the zero product property (this states that any number times zero equals zero). So far we have assembled the function as the following:
The function has x-intercepts at (6, 0), and (0, 10). This means that the numerator must equal (0) when (x) is (6) or (10). Using similar logic that was applied to find the denominator, one can conclude that the numerator must be (). Now one has this much of the function assembled
Finally one has to include the y-intercept of (0, 120). Currently, the y-intercept is (60). This is found by multiplying the constants together. (6 * 10) equals (60). One has to multiply this by (2) to get (120). Therefore, one must multiply the numerator by (2) in order to make the y-intercept (120). Thus the final function is the following:
