3+3=6

6*4=24

24/2=12

12 ft^2

The area of the square is (12in) ^2

The area of the triangle is (1/2)(12in)(8in)

Compute these separately...... then, add them together to get your answer.

For triangle 8*12/2=4*12

4*12=48

For square

12*12=12^2

12^2=144

144+48=192

192 in^2

you have zero 0!

Thanks, h7.........(I believe the answer should be in sq. yds. rather than sq inches)

Where have you been all day?

To find the area, just multiply the width (12 yd) by the length (height) (7 yd).

12*7=84

84 yd^2

Back off she's mine you little s**t

Base*Length/2=triangle area

Base is 12

Length is 5

12*5/2=30

So 30 ft^2

asin is the same as inverse sin

The form we want is:

$${\mathtt{y}} = {\mathtt{mx}}{\mathtt{\,\small\textbf+\,}}{\mathtt{b}}$$

m = Δy/Δx

Δy = $$y_{2}$$-$$y_{1}$$

Δx = $$x_{2}$$-$$x_{1}$$

$${\mathtt{m}} = {\frac{\left({\mathtt{\,-\,}}{\mathtt{4}}{\mathtt{\,-\,}}{\mathtt{5}}\right)}{\left({\mathtt{\,-\,}}{\mathtt{8}}{\mathtt{\,-\,}}{\mathtt{4}}\right)}}$$ 

So m = 0.75.

$${\mathtt{b}} = {\mathtt{y}}{\mathtt{\,-\,}}{\mathtt{mx}}$$

We take one of the points and insert its coordinates into y and x.

b = 5 - 0.75 * 4 = 17

So the form is $${\mathtt{y}} = {\mathtt{0.75}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{17}}$$

I believe it is number 1

I am with Happy7 you asked the question so your cheating if it was on a test!!!!.......

9i x 5i  =  (9x5) x (i x i)  =  45i²

Since i²  =  -1:      45i²  =  45(-1)  =  -45

In this right triangle, when referring to ∠B, the name given to side a is "adjacent" and the name given to side c is "hypotenuse".

Again referring to ∠B, cos = adjacent/hypotenuse, so:  cos(∠B) = a/c   --->  cos(∠B)  =  5/13.

To find the size of ∠B, use cos^-1   --->  ∠B  =  cos^-1(5/13)  --->   ∠B  =  67.38°.

No.

For example, say that x = 30°:

cos(30°)  =  √3/2     (approximately 0.8660)

sec(x) = 1 / cos(x)   --->   sec(30°)  =  1 / (√3 / 2)  =  2/√3    (approximately 1.1547)

-sec(30°) + 1  =  -2/√3 + 1   (approximately -0.1547)

And, this isn't cos(30°).

A formula for the n^th term of a geometric sequence is:  t_n  =  a·r^n-1  

     where a is the first term, n is the number of the term, and r is the common ratio.

If the fifth term is 972 and the common ratio is 3  --->   t₅  =  972 and r = 3:   

     t₅  =  a·3^5-1   --->     972  =  a·3⁴   --->   972  =  a·81   --->   a  =  972/81  =  12

x^2+15x-2

x^2+15x-2 = (x+a)(x+b)

a plus b makes -2

a times b makes 15

a = -5 and b = -3

if (x+a)(x+b) = 0

either (x+a) = 0 or (x+b) = 0

so (x+-5) = 0 or (x+-3) = 0

or x is either 5 or 3

m^-5  =  1/m⁵

32  =  2⁵

m^-5  =  1/32   --->  1/m⁵  =  1/2⁵   --->   m⁵  =  2⁵   --->  m  =  2

Yep he has asked me really creepy questions he wants to know where I live, how old I am, what gender, what grade I am in, and other creepy stuff!!!!!

Exactly 322 years. My bad
