Lets simplify this

2x^2 + 2x - 10 _< 2

4x^2 - 10 _< 2

4x^2 _< -8

x^2 _< -2

x _<1.41
on the graph plot a line, then a filled in cirlce at 1.41

What is angle F to the nearest degree?
nekit [7.7K]

Answer:

So we already knew all three sides, there are more than one way to do it, for example:

sin∠F = HG/HF = 12/13

cos∠F = GF/HF = 5/13

tan∠F = HG/GF = 12/5

ctg∠F = GF/HG = 5/12

All of them will give you the result which is approximately 67°.

Confused on the function and method for this... help me out please.
mezya [45]

Answer:

∠ YZX ≈ 19.7°

Step-by-step explanation:

using the sine ratio in the right triangle.

sin YZX = \frac{opposite}{hypotenuse} = \frac{XY}{YZ} = \frac{7.5}{22.3} , then

∠ YZX = sin^{-1} ( \frac{7.5}{22.3} ) ≈ 19.7° ( to 3 significant figures )

Tank a has a capacity of 9.5 gallons. 6 1/3 gallons of the tank's water are poured out. how many gallons of water are left in th
Advocard [28]

Answer:

Water left in tank is 3\frac{1}{6} gallons.

Step-by-step explanation:

Given :

Capacity of tank = 9.5 gallons  =\frac{95}{10}

Water taken out of tank =6\frac{1}{3}=\frac{19}{3} gallons

We have to find the water left in the tank.

Water left in the tank = Total capacity of tank - water taken out of tank

                                    =\frac{95}{10}-\frac{19}{3}

Taking LCM of (3,10)= 30

\Rightarrow \frac{95 \times 3-19 \times10}{30}

Solving further, we get,

\Rightarrow \frac{285-190}{30}

\Rightarrow \frac{95}{30}=\frac{19}{6}=3\frac{1}{6}

Thus, Water left in tank is 3\frac{1}{6} gallons..
