Answer:

[tex]\sin(30)[/tex]

Step-by-step explanation:

Given

[tex]\sin(23) \cos(7) + \cos(23) \sin(7)[/tex]

Required

An equivalent expression

The above is an illustration of the sine formula which states:

[tex]\sin(A) \cos(B) + \cos(A) \sin(B) = \sin(A + B)[/tex]

In this case:

[tex]A = 23\\ B = 7[/tex]

So:

[tex]\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(23 + 7)[/tex]

[tex]\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(30)[/tex]

Hence, an equivalent expression is: [tex]\sin(30)[/tex]

The composite function is

[tex](f \circ g)(x) = 3x^2 + 5[/tex]

Step-by-step explanation:

Composite functions:

Suppose that we have two functions, f and g. Their composite is given by:

[tex](f \circ g)(x) = f(g(x))[/tex]

In this question:

We have that:

[tex]f(x) = 3x + 2[/tex]

[tex]g(x) = x^2 + 1[/tex]

The composite function is:

[tex](f \circ g)(x) = f(g(x)) = f(x^2+1) = 3(x^2 + 1) + 2 = 3x^2 + 3 + 2 = 3x^2 + 5[/tex]

The composite function is

[tex](f \circ g)(x) = 3x^2 + 5[/tex]

Answer:

44.04°

Step-by-step explanation:

We would use the Law of Sines, [tex] \frac{sin(A)}{a} = \frac{sin(B)}{b} =\frac{sin(C)}{c} [/tex]

Applying the formula, let's find b°:

Thus:

[tex] \frac{sin(b)}{3.6} = \frac{sin(100)}{5.1} [/tex]

Cross multiply

[tex] sin(b)*5.1 = sin(100)*3.6 [/tex]

Divide both sides by 5.1

[tex] sin(b) = \frac{sin(100)*3.6}{5.1} [/tex]

[tex] sin(b) = 0.69516 [/tex]

[tex] b = sin^{-1}(0.69516) [/tex]

b = 44.0399685° ≈ 44.04° (2 decimal places)

Answer:

PEMDAS

Step-by-step explanation:

The order of operations is the order in which you solve an equation to find the correct answer. This is very important because randomly solving parts of an equation without using the order of operations will result in the wrong answer. The order of operations is PEMDAS which stands for: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Example:

[tex](2*2)^{2}+6/3-1[/tex]

Using PEMDAS to solve this equation we get 17 as our answer. However, if we solve it in order of how it appears we end up with 19/3 or 6.33, which is a very different answer.

The inequality is solved and the solution is x > 8/3

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

18 - 3x < 10

Adding 3x on both sides , we get

3x + 10 > 18

Subtracting 10 on both sides , we get

3x > 8

Divide by 3 on both sides , we get

x > 8/3

Hence , the inequality is x > 8/3

Step-by-step explanation:

The joint relative frequency of being a child who prefers watermelon is 132/445 option (A) Divide 132 by 445 is correct.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the frequency cell by the total frequency.

To find the joint relative frequency of being a child who prefers watermelon:

Total number of children who prefers watermelon = 132

Total number of children and adults = 445

joint relative frequency of being a child who prefers watermelon:

= 132/445

Thus, the joint relative frequency of being a child who prefers watermelon is 132/445 option (A) Divide 132 by 445 is correct.

Answer:

Step-by-step explanation: The equation is s = 9.8 – 9.8e-0.88t and we need to find the speed if t or time = 2 so to solve this equation algebraically you would;

[tex]s = 9.8-9.8e-0.88(2)[/tex]

[tex]s = 9.8-9.8e-1.76[/tex]

[tex]s = 8.04-9.8e[/tex]

and after graphing it you would get

Answer: A)  Producers B) Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both. c) Through the photosynthesis process, producers, such as grass, absorb the sun's light energy to produce food (stored sugar and starches). Consumers cannot make their own food, so they have to consume other organisms. The food of almost any kind of animal can be traced back to plants and the sun.

9514 1404 393

Answer:

Step-by-step explanation:

The figure is a composite of a cylinder added to a cone.

The height of the conical portion is (20 m -14 m) = 6 m. We know that the volume of a cone is 1/3 the volume of a cylinder with the same dimensions. Another way to think of that is the volume of a cone is the same as that of a cylinder of 1/3 the height.

So, this figure has a volume equivalent to that of a 14 m tall cylinder topped by a (6 m)/3 = 2 m tall cylinder. Effectively, we're seeking the volume of a cylinder of radius 4 m and height 16 m.

  V = πr²h

  V = π(4 m)²(16 m) = 256π m³ ≈ 804.248 m³

The volume of the "silo" is 256π ≈ 804.25 m³.

If you use 3.14 for π, you will get 803.84 m³.
