Answer:

The y-intercept is at (0,40).

Step-by-step explanation:

y = f(x)= 5(x+4)^3/2

We find the y-intercept but putting x = 0 and evaluating:

y = f(0) = 5(0 + 4)^2^3/2

= 5*4^3/2

= 5*(√4)^3

= 5 * 2^3

= 5*8

= 40.

Answer:

Step-by-step explanation:

In Δ PQS and ΔPQT

∠QPS = ∠RPT {Common angle}

∠PSQ = ∠PTR = 90° {QS & RT are altitude}

QS = RT {given}

ΔPQS ≅ ΔPRT {A A S congruent}

PQ = PS {CPCT}

So, PQR is an isosceles triangle.

a) Flas card (I) and (iii) are congruent.

b) A S A congruent

c) BC ≅ RP

Answer:

C. 2,150

Step-by-step explanation:

We know that out of 120 passengers, 86 were satisfied with the service.

To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%).

Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150.
