Find the area of a triangle whose vertices have the coordinates (-1,1) (-1,5) (4,1)
Alekssandra [29.7K]

The triangle that forms is a right-angled triangle. To work out the area, you just do the base × height, all divided by 2.

Therefore, you do 5 (the base) × 4 (the height) and you get 20.

Then you divide by 2 to finish the equation and you should find that the total area of the triangle is 10 units² (20 ÷ 2 = 10).

Hope that helps :)

The Ramos family wants to buy a Play Station 4 for $299.00, along with accessories and games. A wireless controller costs $44.99
Lilit [14]

Answer:

Part A: 299 + 45A + 30B + 50c

Part B: 569 (or 570 if you round it up)

Step-by-step explanation:

Part A:

Because there is no variable for the number of PlayStation 4s, let's assume that there is only one. That will be 299.

If A is the number of wireless controllers and each wireless controller is worth 45 dollars each, the price for the wireless controller(s) is 45A.

If B is the number of wireless controller charging stations and each wireless controller charging station cost 30 dollars, then the price of the wireless controller charging station(s) is 30B

If C is the number of games and each game cost 50 dollars, then the price of the game(s) is 50C

Put that all together, and we get 299 + 45A + 30B + 50c.

Part B:

Let's plug the numbers into the formula.

A = 2

B = 1

C = 3

299 + 45A + 30B + 50c = 299 + 90 + 30 + 150 = 569\ dollars

How do i find the area of a trapezoid (pictures provided)
scoray [572]

Answer:

(10x - 5) square units.

Step-by-step explanation:

Let the lengths of equal sides be x units.

Hence, AB + AD + DC = x + x + x = 3x

Therefore, BC = 3x - 2

Area  \: of \:  trapezoid  \\ =  \frac{1}{2} (AD + BC)  \times 5 \\  = \frac{1}{2} (x + 3x - 2)  \times 5  \\ = \frac{1}{2} (4x - 2)  \times 5  \\ = \frac{1}{2} \times 2 (2x - 1)  \times 5  \\  = (2x - 1) \times 5 \\  = (10x - 5) \:  {units}^{2}

The angle 01 is located in Quadrant I, and sin(01)=1/2 what is the value of cos(01)
vovikov84 [41]

Answer:

The value of Cos(01) is 0.866 or √3/2

Step-by-step explanation:

In this question, we are asked to calculate the value of cos (01) given the value of sin(01)

Now, given the value of sin (01), we can calculate the value of cos (01).

To get the value of 01, we simply find the value of the arc sin 01

Mathematically since sin (01) = 1/2

(01) = arc sin (1/2)

(01) = 30 degrees

Now since 01 = 30 degrees

cos 01 = Cos (30) = 0.8666 or simply √3/2
