p(l)=1-0.2=0.8 l=lose

1)0.8*0.2=0.16

2) 0.8²*0.2=0.128

3) 0.8^3*0.2=0.1024

Answer:

Step-by-step explanation:

8p+3f=10.39

5p+4f=10.51

subtract

3p-f=-0.12

f=3p+0.12

8p+3(3p+0.12)=10.39

17p=10.39-0.36

17p=10.03

p=10.03/17=0.59

f=3×0.59+0.12=1.77+0.12=1.89 $

or 40 p+15f-40p-32f=51.95-84.08

-17f=-32.13

f=1.89 $

What is the percent of change from 10 to 5?
NNADVOKAT [17]

Answer:

50% decrease

Step-by-step explanation:

\dfrac{(V_2-V_1)}{|V_1|} \times 100

= \dfrac{(5 - 10)}{|10|} \times 100

= \dfrac{-5}{10} \times 100

= -0.5 \times 100

= -50\% \; \text{change}

= 50\% \; \text{decrease}

Sin (3x+19)=Cos(5x-25) <br> What is the value of x? <br> A) 6 <br> B) 12 <br> C) 18 <br> D) 24
malfutka [58]

Answer:

B

Step-by-step explanation:

Using the cofunction identity

sin x = cos(90 - x)

Given

sin(3x + 19) = cos(5x - 25), then

3x + 19 = 90 - (5x - 25)

3x + 19 = 90 - 5x + 25

3x + 19 = 115 - 5x ( add 5x to both sides )

8x + 19 = 115 ( subtract 19 from both sides )

8x = 96 ( divide both sides by 8 )

x = 12 → B
