Length = 12 m and width = m.
Solution:
Let the width of the rectangle be w.
Length of the rectangle = 2w + 5
Area of the rectangle given = 42 m²
<em>Area of the rectangle = length × width</em>
length × width = 42
(2w + 5) × w = 42
Subtract 42 from both sides, we get
Using quadratic formula,
Here,
Dimension cannot be in negative, so neglect w = –6.
Width of the rectangle = m
Hence length = 12 m and width = m.
Answer:
A
Step-by-step explanation:
Using the rule of exponents
×
⇔
, thus
Given
×
=
, that is
=
Since the bases are the same equate the exponents
4 + m = 8 ( subtract 4 from both sides )
m = 4 → A
In the given graph point B is a relative maximum with the coordinates (0, 2).
The given function is .
In the given graph, we need to find which point is a relative maximum.
<h3>What are relative maxima?</h3>The function's graph makes it simple to spot relative maxima. It is the pivotal point in the function's graph. Relative maxima are locations where the function's graph shifts from increasing to decreasing. A point called Relative Maximum is higher than the points to its left and to its right.
In the graph, the maximum point is (0, 2).
Therefore, in the given graph point B is a relative maximum with the coordinates (0, 2).
