Answer:
obtuse, isosceles
Step-by-step explanation:
We have two angles that have the same measure - that means two sides are equal length. That means the triangle is isosceles
We have one angle that is greater than 90 degrees - that tells us the triangle is obtuse
Answer: I took a quick guess but 0.30+0.30 is 0.60 so if for two pounds it equals 2.50 per bag then 2.50 minus 0.60 would be $1.90 profit
Step-by-step explanation:
Since this polynomial has 4 terms, factoring by grouping should be the first thing we try here.
So, we have:

So, we can use ZPP to find out roots:

So our three roots are:

Answer:
0.47x + 7.72
Step-by-step explanation:
We have to create a Linear model using the given two points on the graph. The two points are: (21, 17.5) and (43, 2.75)
The general equation of the line in slope intercept form is
y = mx + c
where m is the slope and c is the y-intercept.
Calculating the slope:

Using the value of m in above equation we get:
y = 0.47x + c
Calculating the y-intercept:
Using any of the given points we can calculate the value of c. Using the point (21, 17.5) in the above equation, we get:
17.5 = 0.47(21) + c
c = 17.5 - 0.47(21)
c = 7.63
Therefore, the equation is:
y = 0.47x + 7.63
Hence option a is the correct answer. The slight change in the value of "c" is because of rounding the value of m to 2 decimal places.
So from the given options, the correct answers is:
y = 0.47x + 7.72
Answer:
2 possible values
Step-by-step explanation:
The given expression is:
![\sqrt[3]{\frac{144}{y} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B144%7D%7By%7D%20%7D)
In order for this to result in a whole number, 144/y must be a perfect cube, the possible perfect cubes (under 144) are:
1, 8, 27, 64, 125
The values of y that would result in those numbers are:

Only two values of y are integers, therefore, there are only two possible values of y for which the given expression results in a whole number.
