Answer:
On a coordinate plane, a cosine curve has a maximum of 4 and a minimum of negative 2.
Step-by-step explanation:
Given:
To find: maximum and minimum of the cosine curve
Solution:
A coordinate plane is a two-dimensional plane formed by the intersection two axis: x-axis and y-axis.
These two axes are perpendicular to each other.
As per the image drawn below,
a cosine curve has a maximum of 4 and a minimum of negative 2 on the coordinate plane.
The correct answer is: 5.7109x10^6
<h2>Answer:</h2>
11 and 15
<h2>Explanations:</h2>
Given the arithmetic sequence -1, 3, 7 __, __, you are to find the next two terms of the sequence.
The nth term of an arithmetic sequence is given as;
where:
• a is the ,first term
,
• n is the ,number of terms
,
• d is the ,common difference
From the given sequence;
a = -1
d = 3 - (-1) = 7 - 3 = 4
For the fourth term, n = 4;
For the fifth term, n = 5;
Therefore the next two terms of the arithmetic sequence are 11 and 15.
