Answer:
a ≈ 11.3, C ≈ 24.2, B ≈ 103.8
Step-by-step explanation:
The information A = 52°, b = 14, c = 6 lends itself to solution using the Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A.
Here, a^2 = 14^2 + 6^2 - 2(14)(6) cos 52 degrees, or
= 196 + 36 - 168 (0.616)
= 120.57
Taking the positive square root of this results in a = 11.3.
This corresponds to the second answer choice: a ≈ 11.3, C ≈ 24.2, B ≈ 103.8
Answer:
C) CA=40
Step-by-step explanation:
2y/(2y+4)=(2y+6)/4y
cross multiply
8y²=4y²+20y+24
4(2y²)=4(y²+5y+6)
divide both sides by 4
2y²=y²+5y+6
y²-5y-6=0
(y-6)(y+1)=0
So the answer must be either 6 or -1. Since it can't be a negative number, it must be 6.
CA=2(6)+4+4(6)
CA=12+4+24
CA=40
Answer: -4
Step-by-step explanation:
-1.5(4-r)=-12
Divide both sides by -1.5
4-r=8
-r=4
r=-4
Therefore, the value of r is -4
This equation is written in point-slope form (y-y1)=m(x-x2). Since the variable m always represents slope in basic mathematics then the slope is 5.
Answer:
B. 90 pounds.
Step-by-step explanation:
19 pounds would be too light, 900 pounds would be too heavy, and 9 tons is equal to 18,000 pounds which is wayy too heavy.
Hope this helps!
