Answer:
a.)x² + y² = 900
b.)y = √900 - x²
Step-by-step explanation:
P.S - The exact equation is as follows :
As given,
The shape of the roller coaster is a half of a circle. Center the circle at the origin and assume the highest point on this leg of the roller coaster is 30 feet above the ground.
a.)
Equation of circle be x² + y² = r²
As given , leg of the roller coaster is 30 feet above the ground.
⇒ r = 30
⇒x² + y² = 30²
⇒x² + y² = 900
∴ we get
Equation of height of Roller coaster - x² + y² = 900
b.)
As we have, x² + y² = 900
⇒y² = 900 - x²
⇒y = √900 - x²
Answer:
this only goes to the thousanths.
Step-by-step explanation:
Answer:
volume of the storage body is 576. multiply by 9. she can fit 64 boxes
Step-by-step explanation:
so draw a line at the short end of the body so it would be 6ft x 4 ft x 2ft = 48 ft. then the rest of the body becomes 11 ft (15 ft minus 4 ft) x 8ft x 6ft =528. so 48 + 528 = 576 then you divide 576 by 9 and get 64.
Answer:
2/15
Step-by-step explanation:
If we have that one third of the students play sports, and two fifth of the students who play sports are girls, to find the fraction of all students that are girls and play sports, we just need to multiply both fractions, because the subset of girls who play sports in relation to the total number of students that play sports is inside the set of total number of students that play sports in relation to the total number of students:
So the fraction of students that are girls who play sports is:
(1/3) * (2/5) = 2/15
