Answer:
1 =98
2 = 49
3 = 63
Step-by-step explanation:
Assuming 1 is at the center since it has the dot
<1 = arc 98
<1 = 98
We can find angle 2
<2 = 1/2 the intercepted arc
<2 = 1/2 (98)
<2 = 49
We can find angle 3
Angle formed by 2 chords
<3 = 1/2(arc 70 + arc56)
<3 = 1/2(70+56)
<3 =1/2 (126)
<3 = 63
The answer is C. 2x+3y=12
Answer:
see explanation
Step-by-step explanation:
a
f(0) means find the value of y when x = 0
That is f(0) = 1 ← the point (0, 1) on the graph
b
When f(x) = - 3 means what are the values of x corresponding to y = - 3
From the graph when y = - 3 there are 2 corresponding values of x, that is
x = - 2 or x = + 2
The solution to f(x) = - 3 is x = ± 2
