Answer:
m∠EGC=70°
Step-by-step explanation:
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite
so
m∠EGC=(1/2)[arc EC+arc DF]
<u><em>Find the value of x</em></u>
we have
m∠EGC=(7x+7)°
arc EC=50°
arc DF=10x°
substitute and solve for x
(7x+7)°=(1/2)[50°+10x°]
14x+14=50+10x
14x-10x=50-14
4x=36
x=9
<u><em>Find the measure of angle EGC</em></u>
m∠EGC=(7x+7)°
substitute the value of x
m∠EGC=(7(9)+7)°=70°
<em>Answer:</em>
<em>4 + √15 > 3 + √6</em>
<em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>√15 ≈ 3.87</em>
<em>4 + 3.87 = 7.87</em>
<em>√6 ≈ 2.44</em>
<em>3 + 2.44 = 5.44</em>
<em>7.87 > 5.44</em>
<em>4 + √15 > 3 + √6</em>
<em>Good luck !</em>
Answer:
Option B, y intercept of -4
Step-by-step explanation:
Option A is incorrect because you cannot use the slope because you don't know where or what point to start from.
<em>Option B is correct because the first thing you do is plot the y intercept of -4 and then you find the slope of the line.</em>
<em />
Option C is incorrect because you cannot use the slope because you don't know where or what point to start from.
Option D is incorrect because that is the wrong y intercept.
Answer: Option B, y intercept of -4

where A=final amount
P=principal
r=rate in decimal form
t=time in years
we are given that P=500, r=12%=0.12
we want to find A when t=10, 20, and 30
so


when t=10, 
when t=20, 
when t=30,
