Answer:
a) for all values of x that are in the domains of f and g.
b) for all values of x that are in the domains of f and g.
c) for all values of x that are in the domains of f and g with g(x)≠0
Step-by-step explanation:
a) By definition (f+g)(x)=f(x)+g(x). Then x must be in the domain of f and g.
b) By definition (fg)(x)=f(x)g(x). Then x must be in the domain of f and g.
c) By definition (f/g)(x)=f(x)/g(x). Then x must be in the domain of f and g and g(x) must be different of 0.
Answer:
17.9 units is the answer
Step-by-step explanation:
points are (-7,-2) and (9,6)
Pythagorean theorem can be written as,
![d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{9-(-7))^2 + (6-(-2))^2}\\\\d=\sqrt{(16)^2+(8)^2} \\\\d=\sqrt{256+64} \\\\d=\sqrt{320} \\\\d=17.88](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%20%2B%20%28y_2-y_1%29%5E2%7D%20%5C%5C%5C%5Cd%3D%5Csqrt%7B9-%28-7%29%29%5E2%20%2B%20%286-%28-2%29%29%5E2%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B%2816%29%5E2%2B%288%29%5E2%7D%20%5C%5C%5C%5Cd%3D%5Csqrt%7B256%2B64%7D%20%5C%5C%5C%5Cd%3D%5Csqrt%7B320%7D%20%5C%5C%5C%5Cd%3D17.88)
Rounding off,
d = 17.9 units
Answer:
Original price: 51$
Discount percentage: 40%
-----------
Details
Discount = Original Price x Discount %/100
Discount = 51 × 40/100
Discount = 51 x 0.4
You save = $20.40
Final Price = Original Price - Discount
Final Price = 51 - 20.4
Final Price = $30.60
there you go, coupon A is 20.40$ Dollars less than the price of coupon B, your welcome :)) i wish u best of luck in the exam:)
also, please mark me as brainliest, it would really help me out, thanks :))
