xxMikexx [17]3 years ago
4 0

Answer and Step-by-step explanation:

We~know~that~a~pentagon~has~5~sides. So, to~find~ each~exterior~angle~of~a~regular~pentagon,we'll~have~to~use~the~formula which~is:

\frac{350}{number~of~sides}

Now,~that~we~know~to~use~the~formula~let's~answer~your~question.

\frac{360}{5}= 72

Now,72~is~the~angle~for~each~exterior~angle.~To~check~whether~it's correct~multiply~72~by~5~you'll~get~it~as~360.~So~it's~the~correct~answer!

kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza. Define a variable and write an expression to represent th
Stels [109]

The total cost, if one drink costs $3 is $27.75

  • Let the cost of a pizza be x

  • Let the cost of a drink be y

If kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza, this expressed as x + 4y

Since a pizza costs $12.75, hence x = $12.75

The function becomes 12.75 + 5y

f(y) = 12.75 + 5y

To get the total cost if one drink costs $3, hence;

f(3) = 12.75 + 5(3)

f(3) = 12.75 + 15

f(3) = 27.75

Hene the total cost, if one drink costs $3 is $27.75

Help with this please.
Ivanshal [37]

Answer:

  • True
  • True

Step-by-step explanation:

This question asks you to compare the coordinates of the vertex of each function.

__

The vertex of the function is its minimum, the point where the graph stops decreasing and starts increasing. It is the lowest point on the graph.

<h3>f(x)</h3>

The vertex is (-4, -1). The minimum is -1, located at x = -4.

<h3>g(x)</h3>

The vertex is (1, -25). The minimum is -25, located at x = 1. We know this is the minimum because there are no g(x) values that are lower (more negative).

<h3>comparison</h3>

The minimum of f(x), -1, is greater than the minimum of g(x), -25. TRUE

The x-value of f(x) at its minimum, -4, is less than the x-value of g(x) at its minimum, 1. TRUE
