Equation: The cartridge has a 8 inch length and a 2 inch width.
Solution: l(w) 8(2)= 16 meaning 16 is the area. Meaning we found the length which is 8.
Answer:
17 1/2 in²
Step-by-step explanation:
a=l×w
or in this case a=h×b
2 1/2×7= 17 1/2 in²
None of the answers are correct
(x+3)^2 + 10 first you factor out the (x+3)
(x+3)(x+3) + 10
x^2 + 6x + 9 +10 simplify
x^2 + 6x + 19
Answer:
82° ; 50° ; 52° ;domain error ;51° ; domain error
Step-by-step explanation:
Using a calculator :
sin(A) = 0.9903
A = sin^-1(0.9903) = 82.01 = 82°
6.) cos(A) = 0.6428
A = cos^-1(0.6428) = 49.99 = 50°
8.) tan(A) = 1.2851
A = tan^-1(1.2851) = 52.111 = 52°
9.) cos(A) = 1.2608
A = cos^-1(1.2608) = domain error
10.) sin(A) = 0.7777
A = sin^-1(0.777) = 50.98 = 51°
11.) sin(A) = 1.8330
A = sin^-1(1.8330) = domain error
