We can now solve 1 + u = ±Ket2/2 + 6t for u. u = −1 ± Correct: Your answer is correct. , where K > 0 Notice that u = −1 is a solution. This means that K could also be 0. Since we now know that K ≥ 0 we can let A represent any arbitrary constant and replace ±K with +A to create a more simplified equation. So we could simply write

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
