Answer: (x^2)/25 + (16y^2)/375) = 1
Step-by-step explanation:
since foci are symetrically located on x-axis about origin, the equation of the ellipse must be of the following form:
(x^2)/(a^2) + (y^2)/(b^2) = 1, where a = semi-major axis, and b = semi-minor axis,
and: e = eccentricity = sqrt(a^2 - b^2)/a = 0.25; foci located at (+/- sqrt(a^2 - b^2),0) = (+/- 1.25,0)
---> sqrt(a^2 - b^2) = 1.25 ---> 1.25/a = 0.25 ---> a = 1.25/0.25 ---> a = 5; and sqrt(a^2 - b^2) = 1.25 = 5/4
---> a^2 - b^2 = (5/4)^2 = 25/16; or 5^2 - b^2 = 25/16 ---> 25 - b^2 = 25/16;
---> b^2 = 25 - (25/16) = 25[1 - 1/16] = 25(15)/16 = 375/16
---> (x^2)/25 + (y^2)/(375/16) = 1 ---> (x^2)/25 + (16y^2)/375) = 1
Hope this help...and correct it's been awhile..Let me know
There seems to be no solution, unless you're supposed to use half ages.
Answer: t= 13.4
Step-by-step explanation:
The given equation is 
To solve this equation for 't', we first divide both sides by 
, we get
Taking log on both the sides, we get
Since 
Then,
Hence, the value of t is 13.4.
Answer:
Step-by-step explanation:
Lets calculate the fence first!
15*12=180
Mario needs to paint 180 ft^2
Turn this into a linear equation
250x=180
Divide by 250 on both sides:
x=0.72
So, Mario needs 0.72 Gal of paint to paint the fence!
