Find the volume of the following cone. Round your answer to the nearest integer.

Let a ∈ A. Then a is some integer that is divisible by 4, so we can write a = 4k for some integer k.

We can simultaneously rewrite a as a = 2•2k, so 2 clearly divides a, which means a ∈ B as well.

Therefore A ⊆ B.

Answer:

x > 6

Step-by-step explanation:

The first thing you need to know is that when you solve inequalities, imagine the greater than or less than sign as an equal sign as you solve. Use the same rules as you would use in algebra: do the same thing to one side to the other side. Now the equation is writen as 4 + 3x > 22. The first step is to subtract 4 to take it from that side of the equation and isolate the x. Remember that if you divide or multiply by a negative number, you must flip the inequality sign. Now you subract 4 from both sides as we were saying, the equation is now 3x > 18. The last step is to divide 3 from both sides to isolate the variable. The 3 next to the x represents multiplication. The final answer is x > 6

D. [tex]-2a^2+2a+4[/tex]

Step-by-step explanation:

[tex]d_1=a^2+2a+3\\d_2=2a^2+a+1\\[/tex]

First, substitute both of these equations into [tex]2(d_1-d_2)[/tex]

[tex]2((a^2+2a+3)-(2a^2+a+1))[/tex]

Now, you just simplify. I don't have much to say about it, but here's the steps:

Answer:

$1,080.00

Step-by-step explanation:

$1,500 - 28% = $1,080.00

Step-by-step explanation:

f(x) = -7x² - x

g(x) = 9x² - 4x

(f - g)(x) = (-7x² - x) - (9x² - 4x)

(f - g)(x) = (-7x² - 9x²) + (-x + 4x)

(f - g)(x) = -16x² + 3x

(f - g)(1) = -16(1)² + 3(1)

(f - g)(1) = -16.1 + 3

(f - g)(1) = -16 + 3

(f - g)(1) = -13

Answer:

12 long sleeved

Step-by-step explanation:

30 / 5 = 6

6 x 2 = 12

Answer:

12

Step-by-step explanation:

The 5 part of the ratio relates to 30 short- sleeved shirts.

Divide by 5 to find the value of 1 part of the ratio

30 ÷ 5 = 6 ← value of 1 part , then

2 parts = 2 × 6 = 12 ← long- sleeved shirts

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

As sin(t) = -3 / 5 and in quadrant 4

so cos is positive

a) sin^2(t) + cos^2(t) = 1

(-3/5)^2 + cos^2(t) = 1

cos^2(t) = 1 - (9/25)

cos^2(t) = (25 - 9) / 25 = 16/25

cos(t) = +4/5

b) sin(2t) = 2 sin(t)cos(t)

= 2 * (-3/5) * (4/5)

= -24/25

c) cos(2t) = cos^(t) - sin^2(t)

= (4/5)^2 - (-3/5)^2

= 16/25 - 9 / 25

= 7 / 25

d) tan(2t) = sin(2t) / cos(2t)

= (-24/25) / (7/25)

= -24/7

e) as sin(2t) is negative and cos(2t) is positive

2t is in Quadrant 4

I am not sure for below three

f) cos(t) = cos^2(1/2 t) - sin^2(1/2 t) = 4/5

  cos^2(1/2 t) + sin^2(1/2 t) = 1

by adding and solving

1 + 4/5 = 2 * cos^2(1/2 t)

9/10 = cos^2(1/2 t)

cos(1/2 t) = +- 3/[tex]\sqrt{10}[/tex]

and sin(t) = 2 * sin(1/2 t) * cos(1/2 t) = -3/5

2 * sin(1/2 t) * 3/sqrt{10} = -3/5

sin(1/2 t) = +- 1/sqrt{10}

means here sin and cos for 1/2 t should be opposite signs

so it is either 2nd or 4th quadrant

g) sin( 1/2 t) = +-1/sqrt{10}

h) cos(1/2 t) = +- 3/sqrt{10}

Answer:

4x−y=−3

Step-by-step explanation:

The standard form of a linear equation is Ax+By=C

Rewrite the equation with the sides flipped.

4x+3=y

Move all terms containing variables to the left side of the equation.

Subtract y from both sides of the equation.

4x+3−y=0

Move 3

4x−y+3=0

Subtract 3 from both sides of the equation.

4x−y=−3

Answer:

4x - y = -3

Step-by-step explanation:

Rearrange the equation.

y = 4x + 3

0 = 4x +3 - y

-3 = 4x - y

By applying the exponential and logarithmic functions, we have

[tex]x^{\sin(x)} = \exp \left(\ln \left(x^{\sin(x)}\right)\right)[/tex]

Then in the limit,

[tex]\displaystyle \lim_{x\to0} x^{\sin(x)} = \lim_{x\to0} \exp \left(\ln \left(x^{\sin(x)}\right)\right)[/tex]

[tex]\displaystyle \lim_{x\to0} x^{\sin(x)} = \exp \left( \lim_{x\to0} \ln \left(x^{\sin(x)}\right)\right)[/tex]

[tex]\displaystyle \lim_{x\to0} x^{\sin(x)} = \exp \left( \lim_{x\to0} \sin(x) \ln(x) \right)[/tex]

[tex]\displaystyle \lim_{x\to0} x^{\sin(x)} = \exp \left( \lim_{x\to0} \frac{\ln(x)}{\csc(x)} \right)[/tex]

As x approaches 0 (from the right), both ln(x) and csc(x) approach infinity (ignoring sign). Applying L'Hopitâl's rule gives

[tex]\displaystyle \lim_{x\to0} x^{\sin(x)} = \exp \left( \lim_{x\to0} \frac{\frac1x}{-\csc(x)\cot(x)} \right) = \exp \left( -\lim_{x\to0} \frac{\sin^2(x)}{x\cos(x)} \right)[/tex]

Recall that

[tex]\displaystyle \lim_{x\to0} \frac{\sin(x)}{x} = 1[/tex]

Then

[tex]\displaystyle \lim_{x\to0} \frac{\sin^2(x)}{x\cos(x)} = \lim_{x\to0} \frac{\sin(x)}{\cos(x)} = \lim_{x\to0} \tan(x) = 0[/tex]

So, our limit is

[tex]\displaystyle \lim_{x\to0} x^{\sin(x)} = \exp(0) = \boxed{1}[/tex]

Answer:

Step-by-step explanation:

A relation is a function if every input has exactly one output. The domain and range of a relation that is not a function can have multiple outputs for a single input.

1. A relation is considered a function if every input has exactly one output. To determine if the relation on the right is a function, we can examine the x-values and see if any are repeated. If there are no repeated x-values, then it is a function. If there are repeated x-values, then it is not a function.

2. A relation that is not a function can have multiple outputs for a single input. The domain of a relation refers to the set of all possible input values, while the range refers to the set of all possible output values. Without the relation provided, it is not possible to state the specific domain and range.
