Can someone help solve this
kap26 [50]

Answer:

336 cubic cm

Step-by-step explanation:

Volume of cone + (Volume of Sphere/2)

V (cone) = (πr^{2}h)/3

               = π4^{2}(12) ÷ 3

               = 64π  ≈ 201 cm

V (sphere) = 4/3πr^{3}/2

               = [4/3π(4^3)] ÷ 2

               = (256π/3) ÷ 2

               ≈ 43π ≈ 135

Solve the system of equations
Blababa [14]

Answer:

x = 3

y = 1

Step-by-step explanation:

(2x + 4y = 10) * 2 = (4x + 8y =20)

4x = 20 - 8y

Plug that into the other equation

(20 - 8y) - y = 11

-9y = -9

y = 1

Plug this value into one of the original equations

2x + 4(1) = 10

2x = 6

x = 3

Is the function even or odd?
sweet [91]

Answer:

f(\theta)=\cos(\theta) is an even function.

Step-by-step explanation:

Recall when it means when a function is even or odd. An even function has the following property:

f(-x)=f(x)

And an odd function has the following property:

f(-x)=-f(x)

So, let's test some values for cos(x).

Let's use π/3:

f(\pi/3)=\cos(\pi/3)

From the unit circle, was can see that this is 1/2 (refer to the x-coordinate).

Now, let's find -π/3. This is the same as 5π/3. Thus:

f(-\pi/3)=\cos(-\pi/3)

And again from the unit circle, we can see that this is 1/2.

Therefore, despite the negative, the function outputs the same value.

Cosine is an even function.

Notes:

Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!
