beks73 [17]

Answer:

114.89 degrees

245.11 degrees

Step-by-step explanation:

cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).

so, the first answer for the second quadrant is

114.89 degrees.

the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation

360 - 114.89 = 245.11 degrees

Dvinal [7]

Answer:

t+0.07t=t(1+0.07)=t(1.07)=1.07t

Step-by-step explanation:

There are a couple of  equivalent expressions to the function t+0.07t. For example:

t+0.07t

Factor:

t+0.07t=t(1+0.07)

If you add the terms inside the parentheses:

t(1+0.07)=t(1.07)

Basically you can add the like terms from the start and get the same result.

t+0.07t=1.07t

Therefore:

t+0.07t=t(1+0.07)=t(1.07)=1.07t

An airplane flies 3800 km in 4 hours 45 minutes. What is its average speed in kilometers per hour?
8_murik_8 [283]

Average speed = (distance covered in some time)  /  (time to cover the distance)

4 hours 45 minutes = 4-3/4 hours = 4.75 hours

Average speed  =  (3,800 km) / (4.75 hours)  =  800 km/hr

Help! im awful at these problems!!<br> solve the formula: t=v+k/g for g.
Sedbober [7]

Answer:

g = \frac{k}{t-v}

Step-by-step explanation:

Given

t = v + \frac{k}{g}

Multiply through by g to clear the fraction

tg = vg + k ( subtract vg from both sides )

tg - vg = k ← factor out g from each term on the left side

g(t - v) = k ← divide both sides by (t - v)

g = \frac{k}{t-v}
