Top left is the right answer hope this helps <3
<span>choices....
a. csc = 15/12
sec = 15/9
b. csc = 15/12
sec = 12/15
c. csc = 9/15
sec = 12/15
d. csc = 9/12
sec = 9/15
a = 9 ; b = 12 ; c = ?
Pythagorean theorem: a</span>² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
<span>15 = c
CSC = cosecant function = hypotenuse/opposite = 15/12
SEC = secant function = hypotenuse/adjacent = 15/9
Choice A: </span><span>csc = 15/12 sec = 15/9 </span>
Answer:
1680 possible pizzas
Step-by-step explanation:
Pizza contains 2 different meat and 3 different vegetables.
If there are 5 meats and 8 vegetables, the customer can select any one of 3 types of crust.
Total number of ways to select meat = 5C2
nCr = n! /(n-r)! r!
5C2 = 5! / (5-2)!2!
= 5! / 3!2!
= 10
Total number of ways to select vegetables = 8C3
= 8!/(8-3)!3!
= 8! / 5!3!
= 56
Total number of pizza choice that can be made = 3 * 5C2 * 8C3
= 3*10*56
= 1680 possible pizza
(50-25)/2
25/2
12.5
25+12.5=37.5
42 divided by 25435 = 0.001651
