Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Two secants drawn from outside the circle, then
The product of the external part and the entire secant is equal to the product of the external part and the entire secant of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) ← distribute both sides
9 + 3y = 2 × 11
9 + 3y = 22 ( subtract 9 from both sides )
3y = 13 ( divide booth sides by 3 )
y = 13 ÷ 3 ≈ 4.3 ( to the nearest tenth )
"b" represents the population of bobcats.
1) "t" represents the number of years after 2008.
2) The domain (t) starts at 0 (which is the year 2008) ⇒ t ≥ 0
3) The range (b) starts when t = 0. b =-0.32(0)² + 2.7(0) + 253 ⇒ b ≥ 253
4) The graph is discrete because the population must be in whole numbers.
Answer:
m = y-b/x
Step-by-step explanation:
y = mx + b
0 = - y + mx + b
-mx = -y + b
m = -y + b / -x
m = y - b / x
Answer:
55 hours
Step-by-step explanation:
Write the problem as an equation.
4290-78x=0
Where 'x' is each hour the pond is being drained.
Then, solve.
4290=78x Add 78x to each side of the equation
55=x Divide both sides by 78
Put both values into a ratio
