X * y = -48
x + y = 8

y = -48/x

x -48/x = 8
x^2 - 48 = 8x
x^2 - 8x -48 = 0
x = 12
y = -4

The total number of burgers sold from a restaurant from Monday to Sunday can be modeled by the function f(d)=200d^3 + 542d^2 + 1

DerKrebs [107]

Answer:

Average = 96

Step-by-step explanation:

Average = sum of terms/ number of terms

sum of terms = number of burgers sold

number of terms = number of visitors

d = number of days since Monday which is 7

burgers sold = 200d^3 + 542d^2 + 179d + 1605 substituting d with 7

burgers sold = 200(7)³ +542(7)² + 179(7) +1605

burgers sold =68600 + 26558 + 1253 + 1605

burgers sold =98016

number of visitors= 100d + 321

number of visitors= 100(7) + 321

number of visitors= 700+321

number of visitors= 1021

Average = 98016/1021

Average = 96

[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = 33°

Opposite Leg = x

Hypotenuse = 29

Step 2: Find Angle

Substitute in variables [sine]: sin33° = x/29
[Multiplication Property of Equality] Multiply 29 on both sides: 29sin33° = x
Rewrite: x = 29sin33°
Evaluate: x = 15.7945

Name the kind or kinds of symmetry the following figure has: A

denpristay [2]

It is a straight line of symmetry because if you have a paper A and you fold it, it will form a straight line, and that is also meaning a straight line of symmetry. If you fold it any other way, it will not be a line of symmetry.

Hope this helps you ;)
