Yuri [45]

Answer:

34 feet

Step-by-step explanation:

From the question, we are told that:

If the room is 30 feet high at the center and 90 feet wide at the floor,

Entire width of the room = 90 feet = 2a

a = 90/2 = 45

Height of the room = b = 30 feet

Foci (c)² = a² - b²

c = √a² - b²

c = √45² - 30²

c = √1125

c = 33.541019662 feet

Approximately to the nearest whole number = 34 feet

Denise and Donna should each stand 34 ft from the outer wall so that they will be positioned at the foci of the ellipse

The area of the figure. Use 3.14 for pie

balu736 [363]

Answer:

54.5 $ft^{2}$

Step-by-step explanation:

divide it to one rectangle and two different triangles.

Rectangles area: (8+3)*4 = 44 $ft^{2}$

triangle top: 4*3/2 = 6 $ft^{2}$

triangle bottom: 3*3/2= 4.5 $ft^{2}$

sum the all up: 44+6+4.5 = 54.5 $ft^{2}$

don't know how to do it with π though if that's obligatory

The amount (in megawatts) of energy generated in a country from wind power can be modeled by the function W(t)equalsw0(1.90)

Ad libitum [116K]

Answer with Step-by-step explanation:

We are given that

$W(t)=W_0(1.90)^t$

Where t corresponds to the year 2000=0

a. $W(0)=2540MW$

Substitute the values

$2540\times 10^6=W_0(1.90)^0=W_0$

$W_0=2540MW$

b.In 2004

t=4

$W(4)=2540(1.90)^4$

$W(4)=33101.534 MW$

c.In 2013

t=13

$W(13)=2540(1.9)^{13}=10.68\times 10^6MW$
