Hey there!
I'll assume we're using the slope-intercept form equation:
y = mx + b
m = slope
b = y-intercept
First, we keep the y, because it's value depends on the x value given.
Next, we find the slope. Slope is defined as rise/run, so we take two points on the graph, find how much taller one is from another, and how far right/left they are, put those values over each other, and we have out slope (m).
Finally, we need to determine the y-intercept, and that's as simple as seeing where the line crosses the y axis and writing down that value.
Hope this helps!
Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
₇P₅ is a permutation. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:
nPr = 
₇P₅ = 
= 
= 
= 7 * 6 * 5 * 4 * 3
= 2520
Answer: C
Answer:
C. (Chanterelle mushrooms cost less by $0.90)
Step-by-step explanation:
Divide 11.25 by 2/3, for the total amount of pound for the Cremini.
Do the same thing for Chanterelle, but the numbers given for it.
We than find out that Cremini=16.87, and Chanterelle=15.98
Now that we know Cremini is more that Chanterelle, we need to find the difference, by subtracting The bigger number by the smaller number.
Our answer is 0.89, but we will round it to 0.90.
Now we know that the Cremini costs more by $0.90, and the Chanterelle costs less by $0.90
