Answer:
-18.289
Step-by-step explanation:
From SOHCAHTOA,
using CAH which is COS
CAH=adjacent/hypotenuse
cos 28°=x/19
19cos28°=x
x=19cos28°
x=-18.289
Option B
quantity 3x squared plus 10 end quantity over 2
<h3><u>Solution:</u></h3>
Given that quantity 6x squared plus 20 end quantity over 4
<em><u>To find: simplify the given sentence</u></em>
quantity 6x squared plus 20 end quantity over 4 means that plus 20 over 4
Here the term "over" represents division
So the quantity 6x squared plus 20 end quantity over 4 is written mathematically as:
Let us simplify the above expression
Taking 2 as common term,
<em><u>Thus the above expression is written as:</u></em>
quantity 3x squared plus 10 end quantity over 2
Step-by-step explanation:
10^2 = 100
10^-2 = 1/100 ➡ 0.01
