Answer:

A right triangle is a triangle with one right angle 90 degree. The side opposite the right angle is called the "hypotenuse", and the other two sides are called the legs. The angles opposite the legs, by definition, are complementary.The Pythagorean Theorem states that in all right triangles, a^{2}+b^{2}=c^{2}.

Answer:

-3 4/9

Step-by-step explanation:

The fractions all have the same denominator, so are easily added.

Of course, you know how to add signed integers.

4/9 - 3/9 - 5/9 + 5 - 8

= (4 -3 -5)/9 +(5 -8)

= -4/9 -3

= -(3 4/9)

Find the seventh term of the geometric sequence 1, 2, 4, ... and the sum of the first seven terms. t7= S7=

IrinaK [193]

Answer:

Seventh term is 64

Sum of the first seven terms is 127

Step-by-step explanation:

The common ratio is 2

$a_{n} = a_{1} r^{n - 1}$

n = 7 and the first term is 1. So,

$a_{7} = 1(2^{7 - 1} ) = 2^{6} = 64$

Seventh term is 64

$S_{n} = \frac{a_{1} (r^{n} -1)}{r - 1}$

$S_{7} = \frac{1(2^{7} -1)}{2 - 1}$

$= \frac{128 - 1}{1} = 127$

Sum of the first seven terms is 127

What is the awser to this 8+10f>14−2f

Yakvenalex [24]

Simple....

you have:

8+10f>14-2f

isolate the variable....

8+10f>14-2f
+2f +2f

8+12f>14
-8 -8

12f>6

Now divide....

$\frac{12f}{12} \ \textgreater \ \frac{6}{12}$

--->>>

f> $\frac{1}{2}$

Thus, your answer.
