Answer:
The square root of 15 in exact form but in decimal form its 3.87298334
Step-by-step explanation:
sin(0) = opposite/hypotenuse = 2/5
cos(0) = adjacent/hypotenuse = sqrt21/5
tan(0) = opposite/adjacent = 2/sqrt21 * sqrt21/sqrt21 = 2sqrt21/21
cot(0) = adjacent/opposite = sqrt21/2
sec(0) = hypotenuse/adjacent = 5sqrt21/21
Answer:
y=-1/2x+80
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x) = a(b^x), the initial value is always a, because a is independent of x , so when x changes only b^x changes.ex if a = 2, b = 3, and x = 0: f(0) = 2 (3^0) = 2 If x = 1, then f(1) = 2 (3^1) = 2 (3). If x = 2, then f(2) = 2 (3^2) = 2 (9), as you can see a still the same.
