Answer:
can you show a picture
Step-by-step explanation:
it depends on the situation and the problem but normally you would use the other numbers to figure out what number goes in "x"
Answer:
Step-by-step explanation:
The proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes was :
0.9 − 0.3 ln(t)
the proportion that remembered the number for 5 minutes, we would substitute t = 5 into expression, 0.9 − 0.3 ln(t). It becomes
0.9 − 0.3 ln5
= 0.9 - 0.3 × 1.60943791243
= 0.9 - 0.4828
= 0.4172
Approximately 0.4 to 1 decimal place
540 is the answer because you multiply 3 times 10 times 18 or whatever order you want and you'll get 540 so that's your answer
Answer:
(1) F(n) = 8050 -400n
(2) 16 days
Step-by-step explanation:
Tylor first day he has left 7,250feet left to climb, this means that he has already climbed his 400ft on his first day
This will produce an arithmetic series for the distances left to climb as each day passes
initial climb = 7,250+400 = 7,650
Arithmetic Series
7650 , 7250 , 6850 , 6450 ......
a = 7650 , d = -400
(1) Explicit formula
F(n) = a + (n-1)d
= 7650 + (n-1)(-400)
= 7650 +400 -400n
F(n) = 8050 -400n
(2) 8050 -400n = 1750
6300 = 400n
n = 6300 /400 = 15.75 = 16 days( approximately)
So after 16days (approximately) Taylor will have 1750ft left to climb.
Answer:
-17
Step-by-step explanation:
x - (-z)
Subtracting a negative is like adding
x+z
x = -4 and z = -13
-4 + -13
-17
