That means when x=0
e^-0.2x =e^0=1
So f(0)=15/5=3
Answer:
Rosaria purchased 50 bracelets and 70 necklaces
Step-by-step explanation:
Let the number of bracelets be b and the number of necklaces be n
b + n = 120 •••••(i)
Secondly;
10b + 11n = 1270 ••••(ii)
Total cost of b bracelets at 10 per 1 is 10b
Total cost of n bracelets at 11 per 1 is 11n
Adding both gives 1270
From i, b = 120-n
Substitute this into ii
10(120-n) + 11n = 1270
1200 - 10n + 11n = 1270
n = 1270-1200
n = 70
b = 120-n
b = 120-70
b = 50

Answer:
6 or -6
Step-by-step explanation:
The symbol √ is the square root symbol.
The square root of a number is a number that when you multiply it by itself you get the first number.
For example:
The square root of 9 is 3 since 3 times itself, 3 × 3, is 9.
The square root of 9 is also -3 since (-3) × (-3) is 9.
The question is asking for the positive and negative square roots of 36.
What number multiplied by itself is 36?
The answer is 6 since 6 × 6 = 36 and -6 × -6 = 36
