How do you find the area of a triangle?

Mathematics
1 answer:
Firlakuza [10]4 years ago
3 0

with it's formula

Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.

If y = 5x - 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
anastassius [24]

Answer: B. {[-1,-8),0,-3),(3,12) if im wrong sowwy

Step-by-step explanation: One simple way to solve this is that 0 = B

The formula you use in order to solve this is y= mx+b

                                                                       y= 5x-3

As we know the -3 is b and 0 is always equal to -3 C is the only choice with 0 and -3 and in x is o and y is -3 the input is 0 and the ouput is -3

x is always and input while as y is always an output.

Plz help!!!!!i want to check my answer
RoseWind [281]

Answer:

$360

Step-by-step explanation:

To calculate simple interest (I) use the formula

I = \frac{PRT}{100}

Where P is the principal (deposit), R is the rate of interest and T is time in years.

here P = 3000, R = 4 and T = 3, hence

I = \frac{3000(4)(3)}{100} = \frac{36000}{100} = $360

Graph the following equation <br> y = 2/3x
Oxana [17]

Any equation in the form

y=mx

Is a line. So, we only need to sample two points, and then connect them.

If we choose, for example, x=0 and x=3, we have

x=0\implies y=\dfrac{2}{3}\cdot 0 = 0,\quad x=3\implies y=\dfrac{2}{3}\cdot 3 = 2

So, when x=0 then y=0, i.e. the line passes through the origin (0,0).

Similarly, when x=3 then y=2, i.e. the line passes through the point (3,2).

Connect these two points and you have the line.

What is the slope of the line that passes through the points (10, -6)(10,−6)
BARSIC [14]

Answer:

Undefined

Step-by-step explanation:

The formula for slope is m=\frac{y2-y1}{x2-x1}

So use the x's and y's from the given points to solve for the slope

(10, -6) (10, -6)

m=\frac{-6 - (-6)}{10-10}

m=\frac{0}{0}

The slope for this line would be undefined because a number cannot be divided by 0
