Answer:
Step-by-step explanation:
(y/10)^2+(x/30)^2=1
y^2/100+x^2/900=1
9y^2+x^2=900
9y^2=900-x^2
y^2=(900-x^2)/9, when x=8 we have
y^2=(900-8^2)/9
y^2=(900-64)/9
y^2=836/9
y=9.6 meters
The arch is 9.6 meters above the river at a distance of 8 meters from the center.
All of them except D have no real solutions
Answer:
V = 14.14in^3
Step-by-step explanation:
Use the formula V = 3/4πr^2 to get the volume of a sphere
Substitute r for 1.5 in
V = 3/4π(1.5)^2
V = 14.137166941154in^3
Round to the nearest hundredth to find the approximate volume
V = 14.14in^3
