Answer:
387 km
Step-by-step explanation:
The length of AC, b can be obtained using the cosine rule ; using the cosine relation:
b² = a² + c² - 2ac CosB
b² = 250² + 185² - 2(250*185) Cos125
b² = 62500 + 34225 - 92500 * −0.573576
b² = 96725 + 53055.820
b² = 149780.82
b = sqrt(149780.82)
b = 387.01527
b = 387 km (nearest whole number)
270° clockwise rotation & 90° counterclockwise rotation
Answer:
The lead coefficient is 8
Step-by-step explanation:
This is because it is the biggest number that is right before the x or that is the coefficient.
Cone (not including the vertex)
Cylinder
Answer:
16 square inches
16 inches
Step-by-step explanation:
We know the area formula is A = s² and the perimeter formula is P = 4s, where s is the side length.
Here, s = 4, so plug this value into both equations:
A = s²
A = 4² = 16 square inches
P = 4s
P = 4 * 4 = 16 inches
Both blanks are 16.
