A student is trying to construct triangles using four different sets of angles. Th angles in each set are given below. Which set
sladkih [1.3K]

Well I can't be for sure but I know for a fact its not set IV it's not possible to make a triangle out of all right angles. Set II, well, that isn't right either. You can't make a triangle out of all obtuse angles. Like the right angle one, its not possible you can only use one obtuse or right angle in a triangle other wise it's not going to be a triangle. I'd say go try Set III since that would most likely make an equilateral triangle.

The Pretty Pizza Company wants to open a new pizza place either on the north side of town or the south side of town. They want t
Lubov Fominskaja [6]

multiply the number of blocks by number of people per block

Then divide number of pizza places by that

1st block:

15 blocks x 220 people = 220*15 = 3300

26 pizza places = 26/3300 = 0.0078

2nd Block

175 * 22 =3850

33/3850 = 0.0085

 the first one is just under 0.008 but if you round it to 3 places it is 0.008

 the 2nd are is just over 0.008 ( 0.009 if you round it to 3 places)

 so they would be better off building in the first area, if they build at all.

pychu [463]

Answer:

Domain : 0 ≤ x ≤ 8

Range : 5450 ≤ f(x) ≤ 6588.65

Step-by-step explanation:

Expression representing the money Samantha collected after x years is,

f(x) = 5450(1.024)^{x}

Time 'x' duration for the investment starts from t = 0 and ends at 8 years, so the domain of the given function will be,

Range : 0 ≤ x ≤ 8

Money collected in the fund from 0 to 8 years is,

f(0) = 5450(1.024)^{0}

     = $5450

f(8) = 5450(1.024)^{8}

     = $6588.6

Therefore, range of the graphed function will be,

Range : 5450 ≤ f(x) ≤ 6588.65
