Answer:
=5.1 units
Step-by-step explanation:
To use the sine rule to find the length of c we first need to find the angle at C.
C=180-(13+12)
C=180-25
C=155°
a/Sin A=c/Sin C
Calculating for the value of c using the sine rule:
12/Sin 13=c/Sin 155
c=12 sin 155
=5.07 units
Thus to 1 decimal places, the value of c is 5.1 units.
1. You can expand the coefficients to yield 6, and add the powers since the bases are the same (ie A)
2. y⁻² can also be rewritten as 1/y², so it becomes 1/y² · 1/y⁵ = 1/y⁷ (ie C)
3. Only the x is affected by the power.
4. y = 3·5ˣ doesn't change in slope, so it essentially is similar to a 5ˣ graph.
5. Should be pretty straight forward.
6. Should be pretty straight forward.
7. Should be pretty straight forward.
8. Since x is the length of the border, calculate the area of the frame and subtract that from the area of the square painting. (Remember that the length of the square painting is x - 8, not x - 4)
9. Should be pretty straight forward.
11 - 25 are pretty much similar to each other.
If you have trouble, let me know and I'll walk you through it.
Divide total price by quantity:
15.60 / 6 = 2.60
Unit price = $2.60
A for the first because there are 4 aces and 1 nine of hearts. that makes it 5 cards of the 52 in a deck
d for the second because there are two cards: the queen of heart and and ace of diamond out of the 52
hope this helped :)
