Find the values of x and y. 40 sy 40 xº X = y= 0

Mathematics
1 answer:
Helga [31]2 years ago
5 0

Answer:

x = 30°

y = 5

Step-by-step explanation:

The ∆ where you find x is an isosceles ∆ because two of its sides has a length of 40 each, since the other triangle has equal angles of 60° each, it also has equal length sides of 40.

Therefore, x is a base triangle of the isosceles, thus:

x = ½(180 - (180 - 60))

x = ½(180 - 120)

x = ½(60)

x = 30°

Let's find y.

8y = 40 (sides of an equilateral ∆ are equal)

Divide both sides by 8

y = 5

Sketch the graph of y (x +3)2-4 and identify the axis of symmetry.
masya89 [10]

The axis of symmetry is at x = -3.


This can be found by looking at the basic form of vertex form:


y = (x - h)^2 + k


In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = -4. This means the vertex is at (-3, -4).


It is a fact that the axis of symmetry is a vertical line of x = (vertex value of x). So we can determine that the axis of symmetry is at x = -3

Coyne Corporation is evaluating a capital investment opportunity. This project would require an initial investment of​ $36,000 t
Zarrin [17]

Answer:

$27,643

Step-by-step explanation:

The net present value is the present value of after tax cash flows from an investment less the amount invested.

The formula for the NPV can be found in the attached image.

The NPV can be found using a financial calculator:

The cash flow for year zero = $-36,000

Cash flow from year one to three = $19,000

Cash flow for year four =$19,000 + $5,000 = $24,000

I = 10%

NPV = $27,643

A playground with 4 sides has a perimeter of 73 feet. Three sides of it are 14 feet,19 feet and 25 feet what is the length of th
slamgirl [31]
To find the length of the missing side, subtract all of the known side from the perimeter.

14 + 19 + 25 = 58.
73 - 58 = 15.

The fourth side is 15 feet 

I hope that helps!
