Answer:

2.4

Step-by-step explanation:

Answer:

First, remember that:

[tex]tan(x) = \frac{sin(x)}{cos(x)}[/tex]

and:

[tex]sec(x) = \frac{1}{cos(x)}[/tex]

Then we can rewrite the expression:

[tex]tan(x)*sin(x) + sec(x)*cos^2(x) = A[/tex]

Where A is an equivalent expression.

as:

[tex]\frac{sin(x)}{cos(x)} *sin(x) + \frac{1}{cos(x)}*cos^2(x) = A[/tex]

Then this is:

[tex]\frac{sin^2(x)}{cos(x)} + cos(x) = A[/tex]

Now we can multiply both sides by cos(x), then:

[tex](\frac{sin^2(x)}{cos(x)} + cos(x))*cos(x) = A*cos(x)[/tex]

[tex]sin^2(x) + cos^2(x) = A*cos(x)[/tex]

And we know that the left term of the above equation is equal to 1, then:

[tex]1 = A*cos(x)[/tex]

[tex]\frac{1}{cos(x)} = sec(x) = A[/tex]

And A is equivalent to the original expression, then we get:

[tex]tan(x)*sin(x) + sec(x)*cos^2(x) = sec(x)[/tex]

The simplification of the expression is sec(x)

Answer:

-4 ≤ x ≤ 2,300

If x is a real number, we have infinite solutions.

if x is an integer number, we have 2,305 solutions.

Step-by-step explanation:

We want to write an inequality such that the numbers:

3, -4, 0, and 2,300 are solutions.

If we order these numbers from smallest to largest, we get:

{-4, 0, 3, 2,300}

Then we can write an inequality like:

-4 ≤ x ≤ 2,300

You can see that the four values in the set {-4, 0, 3, 2,300} are solutions for our inequality.

Now, how many solutions does this inequality has?

if x is a real number, then we have infinite solutions.

if x is an integer, then the total number of solutions will be equal to:

number of negative solutions (4)

number of positive solutions (2,300)

the number zero (1)

Then we would have: 4 + 2,300 + 1 = 2,305 integer solutions.

Then the inequality solution will be -4 ≤ x ≤ 2,300. If x is a real number, we have infinite solutions. if x is an integer number, we have 2,305 solutions.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A.  Write an inequality for which 3, -4, 0, and 2,300 are solutions that will be

If we order these numbers from smallest to largest, we get:

{-4, 0, 3, 2,300}

Then we can write an inequality like:

-4 ≤ x ≤ 2,300

You can see that the four values in the set {-4, 0, 3, 2,300} are solutions for our inequality.

B.  The number of the solution to the inequality will be

We have limitless solutions if x is a real number.

If x is an integer, the set of possible solutions will be

The number of negative solutions (4)

The number of positive solutions (2,300)

The number zero (1)

Then we would have: 4 + 2,300 + 1 = 2,305 integer solutions.

Answer:

Complementary angles

Step-by-step explanation:

When two angles add up to 90°, they are Complementary to each other.

Here, ∠DAB = 90° (right angles)

It means, ∠DAB = ∠BAE (vertically opposite angles)

Also, ∠BAE = a + b

So, a+b is equal to 90°. Hence, the correct option is (b) "Complementary angles".

Step-by-step explanation:

Each side of the cookie dough is x long, since there is no given number, the diameter of the plate is also x, its as long as the square is wide, making the radius 1/2x.

The area of the cookie dough is x², the area of the plate is 1/4[tex]\pi[/tex]x².

You have the equation x²- [tex]\frac{1}{4}[/tex][tex]\pi[/tex]x²the equation has a Greatest Common Factor of x² so your factored equation is x²(1-[tex]\frac{1}{4}[/tex][tex]\pi[/tex])

Answer:

7 / 2, or 3.5 is between 3 and 4.

28 / 5, or 5.6 is between 5 and 6

9/4, or 2.25, is between 2 and 3.

28 / 5, or 4.6, is between 4 and 5.

Step-by-step explanation:

To multiply a whole number by a fraction, the actual way to do it is to make the non-fraction over one. So, for example, if we were to do this:

2 * (1/2)

Set 2 as 2/1 (because they are equal)

(2/1) * (1/2)

Then, multiply the numerators together and denominators together.

= 1

But, we can also save time and multiply the non-fraction with the fraction's numerator.

2 * (1/2) =

(2 * 1) / 2 =

2 / 2 =

1

Let's apply this to the problems we have.

7) 5 * (7/10)

Multiply 5 and 7.

(5 * 7) / 10 = 35 / 10 = 7 / 2

This is the answer (unless you want it even more simplified, which would either be 3 and 1/2, or 3.5). However to find what numbers it is between, simplify it further.

7/2 = 3.5

7 / 2, or 3.5 is between 3 and 4.

8) 7 * (8/10)

Multiply 7 and 8.

(7 * 8) / 10 = 56 / 10 = 28/5 = 5.6

28 / 5, or 5.6 is between 5 and 6

9) 3 * (3/4)

Multiply 3 and 3.

(3 * 3) / 4 = 9 / 4 = 2.25

9/4, or 2.25, is between 2 and 3.

10) 6 * (4/5)

Multiply 6 and 4.

(6 * 4) / 5 = 23 / 5 = 4.6

28 / 5, or 4.6, is between 4 and 5.

Answer:

The answer is 71 degrees

Step-by-step explanation:

Answer:

C. 71°

Step-by-step explanation:

In order to find its reference angle, we first need to find its corresponding angle between 0° and 360°. This is easy to do. We just keep subtracting 360 from it until it's below 360. For instance, if our angle is 544°, we would subtract 360° from it to get 184° (544° – 360° = 184°).

In this case, our angle is -289°. 360 - 289 = 71°

Answer:

[tex]\dfrac{1}{27}[/tex]

Step-by-step explanation:

Given that,

a-b = 3

We need to find the value of [tex]\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}[/tex].

We know that,

[tex]27=3^3\\\\9=3^2[/tex]

So,

[tex]\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}=\dfrac{3^3^({\dfrac{1}{3}b})}{3^2^{\dfrac{1}{2}a}}\\\\=\dfrac{3^b}{3^a}[/tex]

We know that : [tex]\dfrac{x^p}{x^q}=x^{p-q}[/tex]

So,

[tex]\dfrac{3^b}{3^a}=3^{b-a}[/tex]

Since, b-a = -3. So,

[tex]3^{b-a}=3^{-3}\\\\=\dfrac{1}{3^3}\\\\=\dfrac{1}{27}[/tex]

So, the value of the given expression is equal to [tex]\dfrac{1}{27}[/tex].

Answer:

Step-by-step explanation:

Use the given information combine with the Pythagorean theorem to set up an equation. The Pythagorean theorem states that ([tex]a^2 + b^2 = c^2[/tex]), where (a) and (b) are the legs of the right triangle (sides that are adjacent to the right angle); and (c) is the hypotenuse (the side opposite to the right angle). Substitute in the given values in the problem,

[tex]a^2 + b^2 = c^2[/tex]

Substitute,

[tex]QO^2 + QP^2 = PO^2[/tex]

[tex]x^2 + 8^2 = (4+x)^2[/tex]

Simplify, distribute

[tex]x^2 + 64 = x^2 + 8x + 16[/tex]

Inverse operations,

[tex]x^2 + 64 = x^2 + 8x + 16\\-x^2\\\\64 = 8x + 16\\-16\\\\48 = 8x\\/8\\\\6 = x[/tex]
