Answer:

See the attachment

Step-by-step explanation:

A unit circle is one whose radius is 1

sin(90) will have coordinates (0,1)

sin(40)= 0.643

sin(40)= P/H= 0.643/1

cos(40)= B/H= 0.766

Similarly for cos(245)= cos(-65)= -0.423/1

                      sin(245)= sin(-65)= -0.906

Simplify completely quantity 4 x squared minus 7 x plus 3 all over x squared plus 5 x minus 6. quantity 4 x plus 1 over quantity
irinina [24]

Answer:

The answer is (4x - 3)/(x + 6)

Step-by-step explanation:

∵ (4x² - 7x + 3)/(x² + 5x - 6)

Factorize the numerator:

4x² - 7x + 3 = (4x - 3)(x - 1)

Factorize the denominator:

x² + 5x - 6 = (x - 1)(x + 6)

∴ (4x - 3)(x - 1)/(x - 1)(x + 6) ⇒ reduce (x - 1) from in up and down

∴ The answer is (4x - 3)/(x + 6) ⇒ the fourth answer

Rectangle is 2/5 in. long and 1/3 in. wide.
VARVARA [1.3K]
Answer:  "<span>\frac{2}{15}   in²</span> " . {that is:  " (2/15) in² . "}. 
___________________________________________
Explanation:
___________________________________________
The formula/equation for the Area of a rectangle:  

A = L * w  ;  

       in which:   L  =  <span>⅖ in ; 
</span>                       w =  ⅓ in;
___________________________
Find the area;  in a "fraction value" ;
_______________________________
   A = L * w    ;  
 
          →  Substitute the given values for "L" (length) and "w" (width);
       and solve for "A" (area) in the "form of a fraction:
__________________________________________________

A   = (2/15) in  *  (1/3)  in ;
 
→ A    = [(2*1) / (5*3)] *  in * in ; 
______________________________________________________
→  Answer:  The area is:  " \frac{2}{15}   in² " .
                                          
                                             {that is, "(2/15) in² " .}.
