Answer:
15i
Step-by-step explanation:
since 15 x 15 is 225, the imaginary number comes into play here. i x i = -1, so 15i x 15i = -225

Answer:
- 2nd force: 99.91 lb
- resultant: 213.97 lb
Step-by-step explanation:
In the parallelogram shown, angle B is the supplement of angle DAB:
∠B = 180° -77°37' = 102°23'
Angle ACB is the difference of angles 77°37' and 27°8', so is 50°29'.
Now, we know the angles and one side of triangle ABC. We can use the law of sines to solve for the other two sides.
BC/sin(A) = AB/sin(C)
AD = BC = AB·sin(A)/sin(C) = (169 lb)sin(27°8')/sin(50°29') ≈ 99.91 lb
AC = AB·sin(B)/sin(C) = (169 lb)sin(102°23')/sin(50°29') ≈ 213.97 lb
Answer:
y=4x+.0004
Step-by-step explanation:
y=4(x+1)^-4
distribute your parenthesis
y=4x+4^-4
do your exponents
y=4x+.004
and thats as far as the problem can be simplified
hope this helps
