The answer is the first 1, 3,929. Because you would have to multiply 0.86 to the 11th power, then multiply that by 20646.
Answer:
x=<u>+</u>
Step-by-step explanation:
Quadratic function =( -b<u>+</u> )/2a
x^2+x+2-y=0
x=-1<u>+</u> /2
x=-1<u>+</u> /2
x=<u>+</u>
Pretty sure this is right. Would appreciate a brainliest
A mountaineer climbed 1000 feet at a rate of x feet/hour
1000 = x ( t 1 ) eq1
5000 = X ( t 2) eq2 ( he climbed additional at different rate )
the rate was 10 feet / hour less than twice the first rate
X = 2x - 10 eq3
take eq1 and eq 2
( total time = t 1 + t 2 = T)
T = 1000/x + 5000/X
but X = 2x-10
T = 1000/x + 5000/( 2x -10)
T = 1000/x + 5000/( 2(x-5))
T = 1000/x + 2500 / (x-5)
