The negative in a = -2 for answer A represents a reflection over the x-axis.
What does the cosine graph usually look like?.....It goes through point (0,1) and decreases.
The graph shown goes through point (0,-2). Since there are no vertical or horizontal shifts, the graph has an amplitude of 2 and reflects over the x-axis.
a=2 for answer D does not represent the reflection over the x-axis.
Answer:
free point tysm and btw this was a gimmie 5(98⁵) 12 -56
Step-by-step explanation:
Answer:
a = 108° and b = 144°
Step-by-step explanation:
The opposite angles of a rhombus are the same and the sum of all the angles of the rhombus is 360°.
So, from the given diagram of the rhombus we can write
2b + 2× 36 = 360
⇒ 2b = 360 - 72 = 288
⇒ b = 144° (Answer)
Again, the each angles of a pentagon is given to be a.
Hence, we can write 3a + 36 = 360
⇒ 3a = 324
⇒ a = 108° (Answer)
Same as before:
side = 3^2 = 9,
6 sides:
TOTAL = 6*9=54
Answer:
A scatter plot is used to determine whether there is a relationship or not between paired date. ... from a Scatter Plot you can make predictions you can draw a line, called a best-fit line that passes close to most of the data points
