Use the formula below.
Let A_0 = 1 because you just want to know the percentage left. Usually that's the initial amount.
t = 15, the number of years past. n = 22, the half-life.
Answer:
533903276940
Step-by-step explanation:
easy
Answer:
b) 6/7
c) 14
Step-by-step explanation:
b) Scale Factor = Red/(Red+Blue) = 8/(8+6) = 8/14 = 6/7.
c) x = 8+6 = 14.
EXTRA TIP: If you aren't sure, think about wheter these triangles are isosceles(from the diagram). Hope this helps!
H = -16t^2 + 36t + 9
At maximum height h' = 0,
h' = -32t + 36 = 0
32t = 36
t = 36/32 = 1.13 s.
Maximum height = -16(1.125)^2 + 36(1.125) + 9 = 29.25 ft
Answer is option d (1.13 s, 29.25 ft)
Answer:
2x - 3
x - 9
Step-by-step explanation:
The root of a problem is the x value that makes the equation equal to zero.
If the factored form of the equation is (2x-3)(x-9) that means if either 2x - 3 or x - 9 is equal to zero, the entire equation will equal zero, because zero times any number is equal to zero.
Therefore you must solve for (2x-3)=0 and (x-9)=0
