The width of the cooling tower at the base of the structure is 40 meters.
<h3>Width of the cooling tower </h3>
Given equation
x²/400 -(y-90)²/1600=1
Solving for the width
Cooling tower width =2√400
Cooling tower width=2×20
Cooling tower width=40 meters
Therefore the correct option is D. 40 meters.

Answer:
Step-by-step explanation:
Given that:
At point (5,3)
To find an equation of the tangent to the curve at the given point,
By without eliminating the parameter
t² + 5 = 4
t² = 4 - 5
t² = - 1
Then;
The equation of the tangent is:
y - 3 = -2x +10
y = -2x + 7
y = 2x - 7
By eliminating the parameter
x = 5 + In(t)
In(t) = 5 - x
The equation of the tangent is:
y - 3 = -2x +10
y = -2x + 7
y = 2x - 7

<u>Profit on each tulip bulb is:</u>
<u>Profit on </u><u>x</u><u> amount of tulip bulbs:</u>
<u>Similarly, profit on </u><u>y</u><u> amount of daffodil bulbs is:</u>
<u>Since the target is $1200, the required equation is:</u>
- (0.40)(0.35)x + (0.45)(0.64)y = 1200
Correct answer option is C)
