tanx sinx+ secx cos^2x. Explain how you do it
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)

Suppose you are making a giant chocolate chip cookie for a raffle. You roll out
a square slab of cookie dough. Then you use a circular plate that touches the
edges of the square slab of cookie dough and cut the cookie out of the dough.
What is the area of the extra dough? Write your answer in factored form.
Please read "Step-by-step" if you're having trouble
Answer:
x²(1-[tex]\frac{1}{4}[/tex][tex]\pi[/tex])
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])

The degree of the function is the highest exponent, which is 5.
The y-intercept is the value when x=0, which is 0.
The function will have 5 zeros since there are 5 distinct factors.
The end behavior will approach negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity [since the degree is odd and the leading coefficient is positive].
The roots/zeros will be at 0, 5, 3, -2, -4 [setting each factor equal to 0]

Answer:
Interst is $30,000
Total Money is $50,000
Step-by-step explanation:
$20,000 x 0.10(divided by 100 since its percent) x 15 = 30,000
You earn $30,000 from interest alone
$30,000 + $20,000 = $50,000

A. Write an inequality for which 3, -4, 0, and 2,300 are solutions B. How many total solutions are there to your equality?
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.
What is inequality?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:
Step-by-step explanation:
Choose 1 answer: A Vertical angles B. Complementary angles C Supplementary angles D None of the above
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".

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]

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.

Person A can paint the neighbor's house 5 times as fast as Person B. The year A and B worked together, it
took them 10 days. How long would it take each to paint the house?
Answer:
Person A paints the house in 12 days.
person B paints the house in 60 days.
Step-by-step explanation:
The together rate is the sum of each separate rate.
Person A can paint the neighbor's house 5 times as fast as Person B.
This means that the rate of person A is 1/x, and the rate of person B is 1/5x.
The year A and B worked together, it took them 10 days.
This means that:
[tex]\frac{1}{x} + \frac{1}{5x} = \frac{1}{10}[/tex]
Multiplying everything by 10x
[tex]10 + 2 = x[/tex]
[tex]x = 12[/tex]
This means that:
Person A paints the house in 12 days.
person B paints the house in 60 days.
