A circular oil spill continues to increase in size.
The radius of the oil spill, in miles, is given by the
function r(t) = 0.5 + 2t, where t is the time in hours.
The area of the circular region is given by the
function A(n) = 772, where r is the radius of the
circle at time t.
Explain how to write a composite function to find
the area of the region at time t.

step-by-step explanation:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
