To mail a letter to Vienna, Austria the post office charges a flat rate of $9.75 and an additional $0.50 for every ounce the let
bearhunter [10]

Missing details

Which type of function model would be appropriate for this situation?

Answer:

Linear function

Step-by-step explanation:

Given

y = 0.50x +9.75

Required

The function model

A function of the form:

y = mx + b

is referred to as a linear function where

m = slope/rate

b=y\ intercept

By comparison:

m = 0.50\ b = 9.75

<em>So, it is a linear function (linear model)</em>

Prove that:
Lorico [155]
A.)

   \csc^2(x) \tan^2 (x)- 1 = \tan^2(x)

Use the identities \csc x = 1 / \sin x and \tan x = \sin x / \cos x on the left-hand side

   \begin{aligned}&#10;\text{LHS} &= \csc^2(x) \tan^2 (x)- 1 \\&#10;&= \frac{1}{\sin^2 (x)} \cdot \frac{\sin^2 (x)}{\cos^2 (x)} - 1 \\&#10;&= \frac{1}{\cos^2 (x)} - 1&#10;\end{aligned}

Make 1 have a common denominator to allow for fraction subtraction
Multiply the numerator and denominator of 1 by cos^2 x

   \begin{aligned} \text{LHS} &= \frac{1}{\cos^2 (x)} - 1 \cdot \tfrac{\cos^2 (x)}{\cos^2 (x)}  \\&#10;&=  \frac{1}{\cos^2 (x)} - \frac{\cos^2 (x)}{\cos^2 (x)} \\&#10;&=  \frac{1 - \cos^2 x}{\cos^2 (x)}&#10;\end{aligned}

Use Pythagorean identity for the numerator.

If \sin^2 (x) + \cos^2(x) = 1 then subtracting both sides by \cos^2 (x) yields \sin^2(x) = 1 - \cos^2(x). We can substitute that into the numerator

   \begin{aligned} \text{LHS} &= \frac{1 - \cos^2 (x)}{\cos^2 (x)} \\&#10;&= \frac{\sin^2 (x)}{\cos^2 (x)} \\&#10;&= \tan^2 (x) && \text{Since } \tan x = \tfrac{\sin x }{\cos x} \\&#10;&= \text{RHS}&#10;\end{aligned}

======

b.)

   \dfrac{\sec(x)}{\cos(x)} - \dfrac{\tan(x)}{\cot(x)} = 1

For the left-hand side:
By definition, \sec(x) = 1/\cos(x) and \tan (x) = 1/\cot (x)

   \begin{aligned}&#10;\text{LHS} &= \dfrac{\sec(x)}{\cos(x)} - \dfrac{\tan(x)}{\cot(x)}  \\&#10;&= \dfrac{ \frac{1}{\cos(x)} }{\cos(x)} - \dfrac{\frac{1}{\cot(x)}}{\cot(x)} \\&#10;&= \frac{1}{\cos^2 (x)} - \frac{1}{\cot^2(x)} &#10;\end{aligned}

Since \cot (x) = \cos (x) / \sin (x)

   \begin{aligned} \text{LHS} &= \frac{1}{\cos^2 (x)} - \frac{1}{\frac{\cos^2(x)}{\sin^2(x)} } \\ &= \frac{1}{\cos^2 (x)} -\frac{\sin^2(x)}{\cos^2(x)} \\ &= \frac{1 - \sin^2(x)}{\cos^2 (x)} \end{aligned}

Using Pythagorean identity, \cos^2(x) = 1 - \sin^2(x) so

   \begin{aligned} \text{LHS} &= \frac{\cos^2(x)}{\cos^2 (x)} \\&#10;&= 1 \\&#10;&= \text{RHS}&#10;\end{aligned}

Svetlana hair is 4 centimeters long. Her hair grows 1.5 cm per month. Svetlana wants her hair to grow so at least 7 cm long. Wri
Andrei [34K]

Let "per month" = m

The inequality is

1.5m + 4 ≥ 7

+ 4: Her hair right now is 4 cm long

1.5m: Her hair grows 1.5 per month (m)

≥ 7: She wants it to be at least 7 or more.

1.5m + 4 ≥ 7 is your answer

hope this helps
