What is the measure of AC

1 answer:

6 0

Angle ABC is an inscribed angle so would be half of the arc.
So, 4x-5.5=1/2(5x+25)
4x-5.5=5/2x+25/2
4x-5.5=2.5x+12.5
4x-2.5x=12.5+5.5
1.5x=18
x=12

So angle ABC=4(12)-5.5=48-5.5=42.5
Arc AC=5(12)+25=60+25=85

Check: 42.5(2)=85

Answer: Arc AC is 85

The graph shows the distance Arlene ran on Saturday preparing for a marathon. What is the rate of change and what does it repres

andreev551 [17]

Answer:

Rate of change = 6 miles per hour

Step-by-step explanation:

Rate of change of the line is represented by the slope of the line.

Formula to get the rate of change is,

m = $\frac{\triangle y}{\triangle x}$

From the graph attached,

Given straight line is passing through two points (2, 12) and (4, 24).

Rate of change = $\frac{y_2-y_2}{x_2-x_1}$

= $\frac{24-12}{4-2}$

= 6

Rate of change of the line = 6 miles per hour

Therefore, rate of change of the graph will define the speed of Arlene.
