Find the solution to the equation below.

Andreyy89

Answer:

B and D

Step-by-step explanation:

The quadratic formula is $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$ . Here a=20, b=-26, and c=8.

Substitute and you'll have:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{26+/-\sqrt{26^2-4(20)(8)} }{2(20)}=\frac{26+/-\sqrt{676-640} }{40)}$

$\frac{26+/-\sqrt{36} }{40}=\frac{26+/-6 }{40}$

This means the solutions are 26 - 6/ 40 and 26 + 6/ 40.

It simplifies to 1/2 and 4/5.

The angle of depression from the top of a lighthouse to a boat is 27*. if the direct distance from the top of lighthouse to the

alisha [4.7K]

Answer:

Correct answer: Db = 411 .18 ft

Step-by-step explanation:

Given:

α = 27° angle of depression

Dt = 462 ft distance from the top of lighthouse to the boat

Db = ? distance from the base of the lighthouse to the boat

Here we have a right triangle with hypotenuse Dt and one leg Db.

By definition

cos α = Db / Dt ⇒ Db = Dt · cos α

Db = 462 · cos 27° = 462 · 0.89 = 411 .18 ft

Db = 411 .18 ft

A train company charges a flat fee of $175, plus $2.50 per mile for a bus. If the band paid exactly $1,875 for three buses, how

Art [367]

Answer:

680 miles

Step-by-step explanation:

1,875=2.5x+175

Minus 175 each side.

1,700=2.5x

Divide both sides by 2.5

680=x

If the band travels 680 miles for $2.50 each mile, plus the flat fee of 175. The total will be 1,875.
