Answer:
-1
Step-by-step explanation:
When b<4
|b-4| is negative
|b-4| = - ( b-4)
- (b-4) / ( b-4) =
Factoring out (b-4)
-1
THis will be the coordinates of the point at a turning point on the graph.
Since the second derivative is positive (=1) it will be a minimum value of f(x).
The value of y is 29
Since x=4, put 4 in 9x
y = 9(4) - 7
y = 36 - 7
y = 29
Answer:
<h2>A = 37 cm²</h2>
Step-by-step explanation:
Look at the picture.
We have two rectangles:
15cm × 2cm and 7cm × 1cm.
Calculate the areas:
A₁ = 15 · 2 = 30 cm²
A₂ = 7 · 1 = 7 cm²
The area of the figure:
A = A₁ + A₂ → A = 30 cm² + 7 cm² = 37 cm²
