answer:

f (2) = 6

step-by-step explanation:

first plug in 2 as x
f(2) basically means x = 2

f (2) = 3(2)^0 - 2(2)^-1 + 4

solve the exponents and use PEMDAS

f (2) = 3(2)^0 - 2(2)^-1 + 4

f (2) = 3 - 1 + 4

2 to the 0th power is 1
3 times 1 is 3 so we get 3
2 to the power of -1 is 1/2 (it gets flipped)
-2 times 1/2 is -1 so we get 1
there is nothing to do with +4 so we bring it down
now, simply solve it using PEMDAS

f (2) = 3 - 1 + 4

f (2) = 2 + 4

f (2) = 6

Find the value of x in the triangle shown below.

nika2105 [10]

Answer:

$x = \sqrt{28}$

Step-by-step explanation:

Given,

Base of the triangle = 6

Hypotenuse of the triangle = 8

Let the height of the triangle = x

Therefore, According to Pythagoras Theorem,

${8}^{2} - {6}^{2} = {x}^{2}$

$= > 64 - 36 = {x}^{2}$

$= > 28 = {x}^{2}$

$= > x = \sqrt{28} (ans)$

name the rational numbers that are not integers from the list below -11,0,57,8.07, sqrt 13, sqrt 4, 2 1/6, -8/45, 1.1919919991..

weqwewe [10]

Sqrt 13 and 1.1919919991... are irrational, meaning that they can't be described in a fraction of one integer over another, like 1/3, 45/44 or 57/107, these numbers are rational. Most irrationals are known constants like e or π, endless non-repeating decimals, or roots of non-perfect numbers like 13, 7, 5 or 2.
