You put the x=6
6³-4(6)²-12(6)+15=15
the end behavior of the function f(x)
the function f(x) must has odd number of roots ( where the graph of a function intersects the x-axis
the width cant be negative so the width of the rectangle would be 8 inches
<h2>19.</h2><h3>Given</h3>
- window width and height are in proportion to building width and height
- window width and height are 11 in and 18 in, respectively
- building height is 108 ft
<h3>Find</h3>
<h3>Solution</h3>
The proportional relation can be written as
... (building width)/(building height) = (window width)/(window height)
Multiplying by (building height) gives
... (building width) = (building heigh) × (window width)/(window height)
... (building width) = 108 ft × (11 in)/(18 in)
... building width = 66 ft
<h2>21.</h2><h3>Given</h3>
- map distance = 6.75 in
- map scale = 1.5 in : 5 mi
<h3>Find</h3>
<h3>Solution</h3>
The distances are in proportion, so
... (map distance) : (actual distance) = 1.5 in : 5 mi
Multiplying by (5 mi)/(1.5 in)×(actual distance), we have
... (5 mi)/(1.5 in)×(6.75 in) = (actual distance) = 22.5 mi
Answer:
15 cm.
Step-by-step explanation:
It is given that,
Central angle 
Arc length = 33 cm
Formula for arc length :
where, s is arc length, r is radius and 
is central angle in radian.
Substitute s=33 and 
in the above formula.
Multiply both sides by 10.
Divide both sides by 
.
Put 
Therefore, the radius of the circle is 15 cm.
Answer:
there is no table, just a list of numbers. we need a table or maybe a ss for reference
