Answer:
Step-by-step explanation:
f(x)=1/(x+1)
f(x)=1/(-0.99+1)=100
i can't see the last choice but i gave an example
i hope it works
Answer:
(10,2)(20,4)(30,6)(40,8)
Step-by-step explanation:
In each bracket the first digit divided by the second is equal to 5
10÷2=5
20÷4=5
30÷6=5
40÷8=5
DFC equals 180 because all triangles add up to 180. And their sides are the same so 180/3=60
If all the flushes were full flushes: 1190 + 3150 = 4340 full flushes in total. Because the full flush uses 1.6 gallons, multiply 4340 and you get 6944 gallons of water used per week before the partial flushes were installed.
(1190 full flushes * 1.6 gallons) + (3150 partial flushes * 0.9 gallons) = 4739 gallons used.
Subtract 4739 gallons from 6944 gallons to get the amount of gallons saved for the week, which is 2205 gallons.
Answer:
x = 12
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
x² = 6(6 + 18) = 6 × 24 = 144 ( take the square root of both sides )
x = 
= 12
