I dont think that a sphere has a volume it only has a area
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
distance formula = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}
(x_1, y_1) = (5, 1)
(x_2, y_2) = (-3, -5)
\sqrt{ [(-3) - (5)]^2 + [(-5) - (1)]^2 }
\sqrt{ [-8]^2 + [-6]^2 }
\sqrt{ 64 + 36 }
\sqrt{ 100 }
= 10
Answer:
Step-by-step explanation:
Given
Options (a) to (d)
Required
Which represents an arrow pointing left
When an arrow points left on an inequality graph, the inequality is either of the following:
or 
From the given options (a) to (d), only fits the above description.
Other options illustrate an arrow pointing to the right
To further explain this;
Looking at (b), we have:
This is rewritten as:
--- the same form as (c) and (d)
