Evaluated to square

denis-greek [22]

Step-by-step explanation:

The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9.

Find the angle of depression from the top of a lighthouse, 260 feet above water to a ship that's 270 feet offshore?

expeople1 [14]

Answer: OPTION C.

Step-by-step explanation:

Observe the triangle ABC attached.

Notice that the angle of depression is represented with $\alpha$ .

Knowing that the top of a lighthouse is 260 feet above water and the ship is 270 feet offshore, you can find the value of $\alpha$ by using arctangent:

$\alpha= arctan(\frac{opposite}{adjacent})$

In this case you can identify that:

$opposite=260\\adjacent=270$

Therefore, substuting values into $\alpha= arctan(\frac{opposite}{adjacent})$ , you get that the angle of depression is:

$\alpha= arctan(\frac{260}{270})\\\\\alpha=43.92\°$

A test driver has to drive a car on a 1-mile track for two rounds in a way, that his average speed is 60 mph. On his first round

Volgvan

to average 60 mph for 2 laps his total speed needs to equal 60 x 2 = 120

his first lap was 40 so his 2nd lap needs to be 120-40 = 80 mph

HURRY LIMITED TIME

lakkis [162]

If g is the gallons of gas, and the truck holds up to 20 gallons, then g can be anything from 0 to 20.

If there is zero gallons of gas (g = 0) then the truck will travel zero miles because M(0) = 17(0) = 0.

The max miles depends on the max gallons of gas, so the miles possible with 20 gallons is M(20) = 17(20) = 340.

So, g ranges from 0 to 20 and M(g) ranges from 0 to 340.
Therefore your answer is the last option.
