Answer:
20°
Step-by-step explanation:
To find ∠C you don't even need 90° unless you would want to check if you are correct. to find ∠C you would just look for the whole triangle, so basically A + B + C = 180.
80 + 30 = 110
180 - 110 = 70
∠C = 70
Then you would take 70° and subtract it to 90° since it is a right angle combined with x and you would get your answer which is 20°.
Rectangle, because it has two lines of symmetry
Step-by-step explanation:
a)
<u>g(3) = 9 </u>
b)
<u>g(-1) = 1</u>
c)
<u>g(-x) = x²</u>
d)
<u>g(2y) = 4y²</u>
e)
<u>g(1 + h) = 1 + h² + 2h</u>
<em>using</em><em> </em><em>the</em><em> </em><em>identity</em><em> </em><em>(</em><em>a</em><em> </em><em>+</em><em>b</em><em>)</em><em>²</em><em> </em><em>=</em><em> </em><em>a</em><em>²</em><em> </em><em>+</em><em> </em><em>b</em><em>²</em><em> </em><em>+</em><em> </em><em>2ab</em>
Answer: 14.38%
Step-by-step explanation:
Worth of stock in Company A = $5990
Percent decrease = 20%
New worth = $5990 - (20% × $5990)
= $5990 - (0.2 × $5990)
= $5990 - $1198
= $4972
Worth of stock in Company B = $2450
Percent decrease = 8%
New worth = $2450 - (8% × $2450)
= $2450 - (0.08 × $2450)
= $2450 - $196
= $2254
Previous total worth = $5990 + $2450
= $8440
Total worth = $4972 + $2254
= $7226
The total percentage decrease in the investor's stock account will be:
= [($8440 - $7226) / $8440] × 100
=( $1214 / $8440) × 100
= 0.1438 × 100
= 14.38%
