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
Im not sure, but i think it should be
( -3, 1 )
( -3, -2 )
( -6, -3 )
Answer:
m = 1
Step-by-step explanation:
11m + 13 = m + 23
<u>Get m by itself by subtracting m from both sides. </u>
10m + 13 = 23
<u>Subtract 13 from both sides.</u>
10m = 10
<u>DIvide by 10.</u>
m = 1

Answer:
√7 ≈ 2.646
Step-by-step explanation:
The law of cosines is applicable. It tells you ...
c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.
Filling in the given information, you have ...
c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7
c = √7 ≈ 2.646
The length of the third side is √7, about 2.646 units.
