Answer:
f(x)= -2|x-3|-1
<em>(Hi Simran! I just wanted to help you with this question though it might be wrong)</em>
Step-by-step explanation:
f(x) = a|x-h|+k
f(x)= a|x-3|-1
-7 = a |0-3| -1
-7 = a |-3| -1 <-- add to -7
-6 = a |-3|
-6 = 3a
-6/3 = a
-2 = a

The equation of the absolute value is f(x)= -2|x-3|-1
Answer:
Believe it or not, we can determine whether a function is linear or nonlinear simply by looking at its graph! Because the rate at which y is changing with respect to x is constant in a linear function, the graph of a linear function is a line, as the name implies. For example, observe the graph of Sophie's function.

Answer:
dA/dt = 169,56 in²/min
Step-by-step explanation:
We have a circular puddle and its area is:
A = π*r² (1) r is the radius of the circular puddle
Differentiating on both sides of the equation we get:
dA/dt = π*2*r*dr/dt (1)
In that expression we know
r = 9 inches and dr/dt = 3 in/min. Therefore plugging these values in equation (1)
dA/dt = π*2*9*3
dA/dt = 169,56 in²/min
Answer:
A₁ = 950 mm²
Step-by-step explanation:
region 1 is a trapezium with area (A₁ ) calculated as
A₁ = h (b₁ + b₂)
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 38 , b₁ = 30 and b₂ = 20 , then
A₁ = × 38 × (30 + 20) = 19 × 50 = 950 mm²
