Use the circle shown to answer the question.
1 answer:
The value of x in the angle ABC is 25.
<h3>How to find the angles in circle?</h3>The measure of an inscribed angle is half the measure of the arc intercept.
In other words, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
Hence, lets find the value of x in the angle ABC.
Therefore,
m∠ABC = 1 / 2 (arc AC)
arc AC = 76 degrees.
Hence,
m∠ABC = 1 / 2 × 76
2x - 12 = 1 / 2 × 76
2x - 12 = 38
add 12 to both sides of the equation
2x - 12 = 38
2x - 12 + 12 = 38 + 12
2x = 50
divide both sides by 2
2x / 2 = 50 / 2
x = 25

The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>How to determine the graph of the function?</h3>The equation of the function is given as:
f(x)=3(2)^x -4
Set x = 0, 1, 2 and 3
f(0)=3(2)^0 -4 = -1
f(1) = 3(2)^(1) - 4 = 2
f(2) = 3(2)^(2) - 4 = 8
f(3) = 3(2)^(3) - 4 = 20
This means that the graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
