45°?
Step-by-step explanation:
The second floor of a building is 20 m above the ground.
From this floor, the angle of
elevation of the top of an eucalyptus tree is 15°
and the angle of depression of the foot of the same tree is 10°
10+15+20=45
Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y² + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²
Answer:
y = ($2500)(1.04)^x
Step-by-step explanation:
The initial value = $2500
The value of the stock is expected to grow at the rate of 4%
Let x represent the number of years since the stock was made available for purchase.
Let y represent the value of the stock x years later.
y1 = amount of money after one year.
y1 = $2500 (100% + 4%)
y1 = $2500 (104%)
y1 = $2500(1.04)
y2 = amount of money after two years
y2 = y1 (100% + 4%)
y2 = y1 (104%)
y2 = y1(1.04)
y2 = $2500(1.04)(1.04)
y2 = $2500(1.04)^2
This will give a pattern
y5 = $2500(1.04)^5
After x years the model of the equation will be y = ($2500)(1.04)^x
A. 10.3 ft^2 should be the right answer
