Think: tan theta = rise / run = 5 cm / 33 cm = 0.152.

Find the angle: theta = arctan (0.152) = 0.151 radian or approx. 8.6 degrees.

Plz help! ASAP! What is the expression shown below

astra-53 [7]

we are given

$\frac{1}{2} (\frac{3}{2} x+6x+1)-3x$

step-1: Simplify expression inside parenthesis

we will combine like terms

so, firstly we will take common denominator

$\frac{1}{2} (\frac{3}{2} x+\frac{2*6}{1*2}x+1)-3x$

$\frac{1}{2} (\frac{3x+12x}{2} +1)-3x$

$\frac{1}{2} (\frac{15x}{2} +1)-3x$

step-2: Distribute 1/2 inside

$=\frac{1}{2} *\frac{15x}{2} +1*\frac{1}{2}-3x$

$=\frac{15x}{4} +\frac{1}{2} -3x$

step-3: Combine like terms

$=\frac{15x}{4}+3x +\frac{1}{2}$

We can find common denominator

$=\frac{15x}{4}-\frac{4*3x}{4*1} +\frac{1}{2}$

$=\frac{15x}{4}-\frac{12x}{4} +\frac{1}{2}$

$=\frac{15x-12x}{4} +\frac{1}{2}$

$=\frac{3x}{4} +\frac{1}{2}$

we can also write it as in mixed form

$=\frac{3}{4}x +\frac{1}{2}$

so, we will get

$\frac{1}{2} (\frac{3}{2} x+6x+1)-3x=\frac{3}{4}x +\frac{1}{2}$

1 1. For f(x) = x²-3 find: (a) f(3) (3 points) (b) f(2+h) (3 points) Answer:

Irina18 [472]

Answer:

f(x) = 1/ x² - 3

f(3) = 1 / 3²- 3

=1/6

f(2+h) = 1 / (2+ h) ² - 3

= 1 / 4 + 4h + h² - 3

therefore...

f(2 + h) = 1 / 1 + 4h + h²
