Answer:
4/3
Step-by-step explanation:
Slope is calculated by so now you pul the points (10,2) and (19,14) into that.
=
12/9 can be simplified to be 4/3
Answer:
Center: (1,−4)
Radius: 2
Step-by-step explanation:
1 cm = 10 millimetres
10 cm = 100 millimetres
100 cm = 1,000 millimetres = 1 metre
Therefore:
4 metres = 4,000 millimetres
Answer:
it’s 15x+30y-220
Step-by-step explanation:
Because you distribute and then you add the like terms
1-3 are about trigonometric ratios (SOH CAH TOA). 4, 5 are about the Law of Cosines, and 6 uses the Law of Sines.
1. Sin = Opposite/Hypotenuse
x = 10*sin(40°) ≈ 6.428
2. Sin = Opposite/Hypotenuse
x = arcsin(7/12) ≈ 35.69°
3. Tan = Opposite/Adjacent
x = 18/tan(52°) ≈ 14.063
4. b^2 = a^2 +c^2 -2ac*cos(B)
B = arccos((a^2 +c^2 -b^2)/(2ac)) = arccos((7^2 +13^2 -8^2)/(2*7*13))
B = arccos(11/13) ≈32.20°
5. Same formula.
x = √(a^2 +c^2 -2ab*cos(B)) = √(157-132cos(42°)) ≈ 7.675
6. The ratio of side lengths is the same as the ratio of the sines of the opposite angles.
6/10 = sin(x)/sin(100°)
x = arcsin((6/10)*sin(100°)) ≈ 36.22°
