PLEASE HELP !! I'LL GIVE YOU BRAINLIEST !!
GuDViN [60]

Answer:

B

Step-by-step explanation:

tan45° = 10/x

=> 1 = 10/x

=> x = 10

=> y^2 = 10^2 + 10^2 = 200

=> y = 100*sqrt(2)

=> b

A heated piece of metal cools according to the function c(x) = (.5)^x − 11, where x is measured in hours. A device is added that
Goryan [66]

Answer:

The temperature of metal after five years =  -18.96875

Step-by-step explanation:

Given : Function c(x) = (0.5)^x-11

where x is measured in hours

Another function is added h(x)=-x-3

therefore, the resultant function f(x)=h(x)+c(x)

f(x) = (0.5)^x-11-x-3

For x=5

f(5) = (0.5)^5-11-5-3

f(5) = (0.03125)-19

f(5) = -18.96875

Therefore, The temperature of metal after five years = -18.96875

Can anyone solve this:
ludmilkaskok [199]
So fuctions mean
if
f(x)=x+2 then if you put in 3 for x then
f(3)=3+2=5 so

if x=years after 2000
in 2020 then
2020-2000=20 so x=20
subsitute
f(20)=9204e^0.022(20)

e could be:
1. common base of logarithms (memorised to 15 decmals) 2.718281828459045
2. a computer notation exg if you have 3e11 that means 3 times 10^11

if it is 1
9240 times (2.718281828459045^(0.022 times 20))=( simplify exponent first) 9240 times (2.718281828459045^0.44)=9204 times 1.5527072185113=14291.1 or rounded to 14291

if it is 2
9204 times 10^(0.022 times 20)=9204 times 10^(0.44)=9204 times 254.491 rounded to 254


so the answer dependes on what e represents,

if e is:
1. common base of logarithms (memorised to 15 decmals) 2.718281828459045, then answer is 14291

2. a computer notation exg if you have 3e11 that means 3 times 10^11 =254
