Answer:
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288

A very useful result called the inscribed angle theorem tells us that, given any <em>inscribed angle</em> on a circle (an angle on the inside edge of a circle) the <em>central angle </em>that <em>subtends the same arc</em> is <em>twice the measure of the inscribed angle</em>. I've included a visual example for this problem if any of that vocabulary is unfamiliar.
Here, the inscribed angle ∠C = 87° is attached to the arc DEB. According to the inscribed angle theorem, the central angle swept out by DEB should then be 87 x 2 = 174°. To find the measure of arc DE, we note that arc DEB is just arc DE + arc EB. We're given that arc EB measures 76°, so we subtract that from 174 to find that arc DE = 174 - 76 = 98°
Answer:
3x = 12
x = 4
Step-by-step explanation:
The equation shows that the dance class is three times away from her house, and when you multiply that value by "x" you are solving for the amount of times more the value of "3" is from 12. Therefore, the distance from the dance class is four times farther from her music class if you evaluate the expression.
