Answer:
= (√3+4√2)/2√6
Step-by-step explanation:
To evaluate cos45*/sec30*+cosec60*
First according to trigonometry identity
sec 30 = 1/cos30
cosec 60 = 1/sin60
Substitute
cos45*/sec30*+cosec60*
= cos45/(1/cos30) + 1/sin60
= cos45coss30 + 1/sin60
= 1/√2 * √3/2 + 1/(√3/2)
= √3/2√2 + 2/√3
= (√9+4√2)/2√6 +
= (√3+4√2)/2√6

1/5 (10x - 5)
whoever answers first and at least looks correct gets brainliest!!!
Answer:
2x - 1
Step-by-step explanation:
Simplify. Note that you cannot combine a term with a variable with a constant term. Divide 5 from both terms in the parenthesis:
1/5(10x - 5) = (10x - 5)/5
Divide 5 from both terms in the parenthesis:
10x/5 = 2x
-5/5 = -1
2x - 1 is your answer.

The sum of the squares of two consecutive even integers is 1684. What are the integers?
Answer:
Step-by-step explanation:
Let the 2 consecutive integers be x and x+1.
x²+(x+1)²=1684
x²+(x+1)(x+1)=1684
x²+x²+x+x+1=1684
2x²+2x-1683=0
Using quadratic formular
15. a
16.c
17. e
18.9
19. h
Answer:
19 h
Step-by-step explanation:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115
How do you prove that infinite sequences converge? For example how did someone prove that 1 + 1/4 + 1/9 + 1/16 + 1/25 ..... converges to π^2/6. Can someone explain how people do this, and the process to discovering whether or not infinite sequences diverge or converge? An answer fully explaining the process, that is also fairly clear will receive a brainiliest.

What is the partial fraction decomposition of
7x squared- 6x +9/
3x(4x squared +9)
9514 1404 393
Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
[tex]\dfrac{7x^2-6x+9}{3x(4x^2+9)}=\boxed{\dfrac{1}{3x}+\dfrac{x-2}{4x^2+9}}[/tex]

In parallelogram ABCD, if m angle C= 110° and m angle D - 70°, what is the sum of the measures of LA and 28?
409
909
180°
360°
Answer:
180°
Step-by-step explanation:
ABCD is a parallelogram.
Measures of the opposite angles of a parallelogram are equal. Here [tex] \angle A, \:\: \angle C \: \: and\:\: \angle B, \:\: \angle D[/tex] are opposite angles.
[tex] \therefore m\angle A = m\angle C = 110\degree [/tex]
[tex] \& \:m\angle B = m\angle D = 70\degree [/tex]
[tex] m\angle A + m\angle B =110\degree + 70\degree [/tex]
[tex] m\angle A + m\angle B =180\degree [/tex]

Use the quadratic equation y = –2x^2 + 4x +5 to complete the statements.
Answer:
Step-by-step explanation:
Given quadratic equation is,
y = -2x² + 4x + 5
y = -2(x² - 2x) + 5
y = -2(x² - 2x + 1 - 1) + 5
y = -2(x² - 2x + 1) + 2 + 5
y = -2(x - 1)² + 7
This equation is in the vertex form of the quadratic equation,
y = a(x - h)² + k
where, (h, k) is the vertex of the parabola.
Therefore, vertex of the given quadratic equation is (1, 7)
The equation can be rewritten as y = -2(x - 1)² + 7.
Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).

Answer:
165 is greater than or equal to 17.75x+5.25; 9 is greater than or equal to x
Step-by-step explanation:
The problem states that they have no more than $165. This means that they either use all the money, or they have leftover money, which means you need to use the 'greater than or equal to' sign. It says that tickets are $17.75 a person, and we're trying to find the number of people (x). You can write this as 17.75x. There is also a parking fee to add on to the equation, which is represented as +5.25. Now, we can solve!
I'm going to use an equal sign to replace the inequality symbol, but make sure to add the symbol at the end of the problem.
165=17.75x+5.25
159.75=17.75x
9=x
Our final answer is 9 is greater than or equal to x. Hope this helps!
Answer:
The inequality is $17.75x + $5.25 ≤ $165
and the amount of people who can go is 9
Step-by-step explanation:
if you subtract 5.25 from both sides, you'll get
17.75x ≤ 159.75
and when you divide both by 17.75, you'll get 9
