Answer:

i got you :D

Step-by-step explanation:

f(x)= 2x²+4x-6 and g(x)=2x-2, find each function

1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)

First factor both top and bottom:

(2x-2)(x+3)÷(2x-2) = x+3

2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->

2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:

2a^2+8a+8+4a+2, combine like terms

2a^2+12a+10

4500 \times 7\% \\  = 4500 \times  \dfrac{7}{100}  \\  = 315
36 months = 3 years
315 \times 3 = 945
Answer is B.

2.
420 + 360 = 780 \\ 780 \times 106\% \\  = 780 \times  \dfrac{106}{100}  \\  = 826.8
Answer is B.

3. Answer is C.

4.
1 + 1 = 2 \\ 2 \times 108\% \\  = 2 \times  \frac{108}{100}  \\  = 2.16
Answer is D.

5.
50 \times 105\% \\  = 50 \times  \frac{105}{100}  \\  = 52.5

Elina [12.6K]

Answer:

0.444

Step-by-step explanation:

The objective is to draw the tree diagram and find the probability that the roadrunner took the high road, given that he was caught.

The tree diagram is attached in the image below:

The required probability can be computed as:

P(high\  road  \ | \  caught) = \dfrac{P(high  \ road \  and \  caught)} {P(caught)} \\ \\ P(high \  road  \ |  \ caught) = \dfrac{P(high \  road  \ and  \ caught)}{P(high \  road  \ and  \ caught)+P(low  \ road  \ and  \ caught)}

P(high  \ road \  |  \ caught) =\dfrac{ 0.8*0.01 }{ 0.80*0.01 + 0.20*0.05} \\ \\ P(high \ road  \ | \ caught) = \dfrac{0.008 }{ 0.008 + 0.01} \\ \\

P(high \ road  \ | \ caught) = \dfrac{0.008 }{ 0.018}

\mathbf{P(high \ road  \ | \ caught) = 0.444}
