Ksju [112]

Answer:

Step-by-step explanation:

1. sinФ = cos 25

25 ° is in the between 0 and 90°

therefore it can simply represent

cosФ= sin (90-Ф) = sin (90 - 25) = sin 65

2. sin(Ф/3 + 10) = cos Ф

cos Ф = sin (90 -Ф)

sin(Ф/3 + 10) = cos Ф

sin(Ф/3 + 10) = cos Ф = sin(90-Ф)

Ф/3+10=90-Ф

10Ф+3/30 = 90-Ф

10Ф+3 = 30(90-Ф)

10Ф+3 = 2700-30Ф

10Ф+30Ф=2700-3

40Ф = 2697

Ф = 2697 / 40 = 67.425 ≅ 67.4°

Answer:

$\boxed{\sf \ \ \ 248 \ \ \ }$

Step-by-step explanation:

Hello,

$(fog)(4)=f(g(4)) \ \ \ and \ \ \ g(4)=-6*4^2+9*4+9=-51 \ \ so\\(fog)(4)=f(-51)=-5*(-51)-7=255-7=248$

hope this helps

If the rate of inflation is 2.6% per year, the future price p(t) (in dollars) of a certain item can be modeled by the following

PilotLPTM [1.2K]

Answer:

The current price of the item is $600.

The price of the item 9 years from today will be of $756.

Step-by-step explanation:

Price of the item:

The price of the item, in dollars, after t years, is given by:

$p(t) = 600(1.026)^t$

Current price of the item

This is p(0). So

$p(0) = 600(1.026)^0 = 600$

The current price of the item is $600.

9 years from today.

This is p(9). So

$p(9) = 600(1.026)^9 = 756$

The price of the item 9 years from today will be of $756.
