Answer:

The answer to your question is letter A) cot x

Step-by-step explanation:

$\frac{1 - cot x}{tan x - 1}$

Remember that cot x = $\frac{1}{tan x}$

Then

$\frac{1 - \frac{1}{tan x} }{tanx -1}$

Simplify

$\frac{\frac{tan x - 1}{tan x} }{tan x - 1}$

$\frac{tan x - 1}{tan x (tan x - 1)}$

$\frac{1}{tan x}$

Result

$\frac{1}{tan x} = cot x$

For the function f(x)=3xsquared- 2x+5 find f(1) f(-2) and f(a)

Oksanka [162]

$f(x)=3x^2-2x+5\\\\
f(1):\ \ Substitude\ 1 \ as\ x\ into\ function:\\
f(1)=3*1^2-2*1+5=3-2+5=\textbf{6}\\\\
f(-2)\ \ Substitude\ x=-2\\
f(-2)=3*(-2)^2-2*(-2)+5=3*4+4+5=12+4+5=\textbf{21}\\\\
f(a)\ \ substitude\ x=a\\
f(a)=\underline{3a^2-2a+5}$

If x is the hypotenuse then
hyp^2 = 4^2 + 5^2
hyp^2 = 41
hypotenuse = 6.403124


if x is a leg then
leg^2 = 5^2 - 4^2
leg^2 = 25 - 16
leg^2 = 9

What is the volume of the composite figure?

Romashka [77]

Answer:

1428 in³

Step-by-step explanation:

To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism ( $A= l * w * h$ ) and volume of a triangular prism. $A = \frac{1}{2}(b*h)$

If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:

17 × 8 × 5 = 680 in³.

Solving for the triangular prism gives us:

A = 1/2 (11 × 8 × 17)

A = 748.

Add these two volumes to find the volume of the composite figure:

748 + 680 = 1428 in³
