Answer:
-√2
Step-by-step explanation:
f(x) = sinx + cosx
f'(x) = cosx - sinx
f''(x) = -sinx - cosx
f''(pi/4) = -sin(pi/4) - cos(pi/4) = -√2

Answer:
A
Step-by-step explanation:
The equation will be in the form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line
m =
= - 2
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - 2x + 5 or
y = 5 - 2x → A
Answer:
is 26
Step-by-step explanation:
because i said
Slope = (5 + 4)/(2 +1) = 9/3 = 3
y = mx + b
5 = 3(2) + b
b = -1
equation
y = 3x - 1
answer
y = 3x - 1
