Actually Welcome to the concept of Equilateral triangles.

Since the above triangle is a equilateral triangle, that has all sides equal and also all angles are equal,

by applying the angke sum property of triangle we get as,

==> 6x + 6x + 6x = 180°

hence, 18x = 180°

==> x = 180/18 ==> 10°

hence the value of x = 10°

Let f(x) = -4x - 2 and g(x) = 5x - 6. Find fxg and state its domain.
defon

Answer:

c) -20x^2+14x+12

all real numbers

Step-by-step explanation:

So (fg)(x)=f(x)g(x)=(-4x-2)(5x-6).

Need find the expression in standard form we need to use foil:

First:  (-4x)(5x)=-20x^2

Outer: (-4x)(-6)=24x

Inner:  (-2)(5x)=-10x

Last:  (-2)(-6)=12

--------------------------Add like terms:

-20x^2+14x+12

Polynomials have domain all real numbers.

There are no restrictions on what x can be.  For every number you plug in, you will get a number back.

A cylinder has a height of $10$ and a radius of $3.$ Determine the total surface area, including the two ends, of the cylinder.
My name is Ann [436]

Check the picture below.

\textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=3\\ h=10 \end{cases}\implies \begin{array}{llll} SA=2\pi (3)(10+3) \\\\\\ SA=6\pi (13)\implies SA=78\pi \\\\\\ SA\approx 245.04 \end{array}

Sally is having a party and she has invited nine of her friends.
Alexeev081 [22]

Answer:

1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice

2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c

Step-by-step explanation:

1/2 limes · 10 = 5

1/2 lemons · 10 = 5

100 mL of pineapple juice · 10 = 1,000 mL

200 mL of lemonade · 10 = 2,000 mL

100 mL of orange juice · 10 = 1,000 mL

Cost:

5 limes · 0.4 = $2

5 lemons · 0.5 = $2.5

mL to L

1,000 mL of pineapple juice = 1 L, this costs 90¢

2,000 mL of lemonade = 2 L, this costs $1.60

1,000 mL of orange juice = 1 L, this costs 80¢

Overall:

5 limes for $2

5 lemons for $2.5

1 L of of pineapple juice for 90¢

2 L of lemonade for $1.60

1 L of orange juice for 80¢
