Hello : 
(sec²x - 1) / sec²x  = (sec²x / sec²x) -1/sec²x
                             = 1 -1/sec²x
                             = 1- (1/secx)²
                              = 1 -cos²x
                              = sin²x

Bingel [31]
<span>The height of Gateway Arch shown on the Missouri quarter is 630 feet or 7,560 inches. Find how many 4 inch stacks of quarters make up the height of the Gateway Arch. If there are 58 quarter in 4 inch stack o, how many quarters high is the arch? </span>

<span>Hence to find how many 4 inch stacks of quarters make up the height of the </span><span>Gateway Arch, 

Since the Gateway Arch is 7560 then for every stack is 4 inches to find the stacks all in all, we just have to divide 7560 / 4 = 1890

Then, to find </span><span>how many quarters high is the arch, 
58 quarter x 4 inch = 232 quarters high in inches.

Find the table with unit rates greater than the unit range in the graph. Then arrange these tables in order from least to greate
Lubov Fominskaja [6]

Answer:

Except table 2, all tables have greater unit rate than the graph.

The required arrangements of tables is  

Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6

Step-by-step explanation:

Formula for unit rate :

m=\dfrac{y_2-y_1}{x_2-x_1}

From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is

m=\dfrac{20-0}{11-0}=1.8181...

Similarly, we need to calculate the unit rate for each table.

m_1=\dfrac{26-13}{14-7}=\dfrac{13}{7}=1.85714

m_2=\dfrac{18-9}{10-5}=\dfrac{9}{5}=1.8

m_3=\dfrac{34-17}{18-9}=\dfrac{17}{9}=1.88..

m_4=\dfrac{42-21}{22-11}=\dfrac{21}{11}=1.9090..

m_5=\dfrac{38-19}{20-10}=\dfrac{19}{10}=1.9

m_6=\dfrac{50-25}{26-13}=\dfrac{25}{13}=1.923

m_7=\dfrac{46-23}{24-12}=\dfrac{23}{12}=1.9166..

Except table 2, all tables have greater unit rate than the graph.

The required arrangement of tables is  

Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6
