Answer:
5π/6 radians
Step-by-step explanation:
The whole is the sum of the parts.
∠BAD = ∠BAC +∠CAD
∠BAD = π/3 + π/2 = π(2/6 + 3/6)
∠BAD = 5π/6
Find the slope (m) by using Y2-Y1/X2-X1
Y2 = -1
Y1 = 7
X2 = 4
X1 = 2
(-1 - 7)/((4-2) = -8/2 = -4
Use the point-slope formula to determine the equation. You only need to use one set of points. (2,7) in this case.
(y-Y1) = m(x-X1)
(y - 7) = -4(x - 2)
y-7=-4x + 8
y= -4x + 15
Answer:
x = 5
Step-by-step explanation:
According to the Pythagorean theorem a²+b²=c²
In this case its:
x² + 12² = 13²
169 - 144 = x²
x² = 25
x = 5
Answer: 1. No 2. yes 3. yes 4. no
Step-by-step explanation:
If you locate the points on the graph, 1 and 4 are not in the shaded and 2 and 3 are, which means they are not solutions.
The graph of a linear function is a line
<span>
A)f(x) = -2 line
</span>
B)f(x) = x - 2 line<span>
C)f(x) = 2x </span>line<span>
D)f(x) = x</span>² parabola
So, D)f(x) = x² <span>is not a linear function</span>
