Answer:
63
Step-by-step explanation:
9(7+9) = 63 +81
Answer:
First part:
Set h(t) = 17and solve for t.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
Answer:
d) 0.4
Step-by-step explanation:
P(Ra) = 0.998
P(Rb) = 0.995
P(A) = 0.4
P(B) = 0.6
The probability that method A was performed, given that the eye was recovered within a month of the surgery, is determined by the probability that the eye recovered within a month with method A (P(A) x P(Ra)),divided by the probability that the eye recovered within a month with either method (P(A) x P(Ra) + P(B) x P(Rb)):

The probability that method A was performed is 0.40.
1) f(0) means to find y value when x= 0
x=0, y=2, so f(0) =2
2) f(x) = 0
y=0,x=?
When y=0, x=4
3) f⁻¹(0),
This is an inverse function of f(x),
that means that for f⁻¹, that values of x become y, and values of y become x.
f⁻¹(0)
"0" is y from the graph, when y=0, x=4, so
y=0, f⁻¹(0) = 4
4) f⁻¹(x)=0,
means that on this graph we need x=0, y=2,
so f⁻¹(2)=0,
x=0
For function we had
x=0, y=2
x=4, y=0
For f⁻¹ inverse function we have (x becomes y, and y becomes x)
x=2, y=0
x=0, y=4
