I need to prove this using identites
show all steps
cosx+cos7x/sinx-sin7x=-cot3x
Answer: see proof below
Step-by-step explanation:
Use the following Sum to Product Identities:
[tex]\cos A+\cos B=2\cos \bigg(\dfrac{A+B}{2}\bigg)\cdot \cos \bigg(\dfrac{A-B}{2}\bigg)\\\\\\\sin A-\sin B=2\cos \bigg(\dfrac{A+B}{2}\bigg)\cdot \sin \bigg(\dfrac{A-B}{2}\bigg)[/tex]
Use Even/Odd Identities: cos (-A) = - cos A
sin (-A) = sin (A)
Use Quotient Identity: [tex]\cot A=\dfrac{\cos A}{\sin A}[/tex]
Proof LHS → RHS:
[tex]\text{LHS:}\qquad \qquad \qquad \dfrac{\cos x+\cos 7x}{\sin x - \sin 7x}[/tex]
[tex]\text{Sum to Product:}\qquad \dfrac{2\cos \bigg(\dfrac{x+7x}{2}\bigg)\cdot \cos \bigg(\dfrac{x-7x}{2}\bigg)}{2\cos \bigg(\dfrac{x+7x}{2}\bigg)\cdot \sin \bigg(\dfrac{x-7x}{2}\bigg)}[/tex]
[tex]\text{Simplify:}\qquad \qquad \quad \dfrac{2\cos \bigg(\dfrac{8x}{2}\bigg)\cdot \cos \bigg(\dfrac{-6x}{2}\bigg)}{2\cos \bigg(\dfrac{8x}{2}\bigg)\cdot \sin \bigg(\dfrac{-6x}{2}\bigg)}[/tex]

A practice field is in the shape of a rectangle. The area of the practice field is represented by 5x^2 + 30x -7xy -42y. Find the expressions that represent the length and width of the practice field.
Answer:
length and width are x + 6 and 5x - 7y
Step-by-step explanation:
5x² + 30x - 7xy - 42y
= 5x(x + 6) - 7y(x + 6)
= (x + 6)(5x - 7y)
so
length and width are x + 6 and 5x - 7y

Which of the following would be a correct interpretation of a 99% confidence interval such as 4.1<μ<5.6?
Choose the correct answer below.
A.
It means that 99% of all data values are between 4.1 and 5.6.
B.
There is a 99% chance that μ will fall between 4.1 and 5.6.
C.
It means that 99% of sample means fall between 4.1 and 5.6.
D.
We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of μ.
Explanation:
Imagine you randomly selected n items to form a sample, and you did this 100 times. Each time doing a trial like this, we generate a confidence interval. We expect about 99 of those times to have a confidence interval containing the true value of μ. This is what it means when we say "We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of μ."

1.5x^2+6x+...
Answer:
[tex]1.5x^2+6x+6[/tex]
Step-by-step explanation:
Collect 1.5 from everything, noticing that [tex]6= 1.5\times 4)[/tex]
[tex]1.5(x^2+4x + b^2)[/tex]
Now let's remember that the square of a binomial is [tex](x+b)^2 = x^2+2xb+b^2[/tex], confronting with what we have inside the bracket, [tex]2bx = 4x \implies b=2[/tex]
Our completed bynomial becomes [tex]1.5(x^2+4x+4) = 1.5x^2+6x+6[/tex]
Answer:
1.5x² + 6x + 6
Step-by-step explanation:
1.5x² + 6x + ? = a(x + b)²
a = 1.5
2ab = 6
ab = 3
b = 3/1.5
b = 2
So, inputting all the values :-
a(x + b)²
1.5(x + 2)²
1.5(x² + 4x + 4)
1.5x² + 6x + 6

What is the slope intercept form of (-4,-5); and slope 1/2
Answer:
[tex]y=0.5x-3[/tex]
Step-by-step explanation:
Given the following question:
Point A = (-4, -5) = (x, y)
[tex]m=\frac{1}{2} =0.5[/tex]
To find the slope intercept form of the given information we will have to use the formula y = mx + b where m equals the slope.
[tex]y=mx+b[/tex]
[tex]-5=0.5(-4)+b[/tex]
[tex]0.5\times-4=-2[/tex]
[tex]-5=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]-5+2=-3[/tex]
[tex]b=-3[/tex]
[tex]y=0.5x-3[/tex]
Which means your answer is "y = 0.5x - 3."

A rectangular city is 2 miles long and 7 miles wide. What is the distance between opposite corners of the city? The exact distance is ______________ miles How far is it to the closest tenth of a mile? Answer: The distance is approximately ___________ miles.
Answer:
√53 ≈ 7.3 miles
Step-by-step explanation:
The Pythagorean theorem can be used to find the length of a diagonal of a rectangle. The diagonal is effectively the hypotenuse of a right triangle with leg lengths equal to the side lengths of the rectangle.
__
If c represents the distance between opposite corners, and 'a' and 'b' represent the length and width of the city, then we have ...
c² = a² +b²
c² = 2² +7² = 53
c = √53 . . . . . exact corner-corner distance in miles
c ≈ 7.3 . . . . . . approximate corner-corner distance
The exact distance is √53 miles; to the nearest tenth, the distance is approximately 7.3 miles.

Mary drove 355 miles using 17 gallons of gas. At this rate, how many gallons of gas would she need to drive 284 miles?
Answer: 13.60 gallons divide 355 by 17 to get the base miles per gallon then use that and divide it 284 by 20.88
Step-by-step explanation:
Step-by-step explanation:
17g = 335miles
1g = 335÷17
= 19.70588235
284miles = (284÷19.70588235) × 1
284miles = 14.4119403
Answers:
284miles = 14.41gallons (2.dp)

Answer:
2.042 meters hope this helps
The height of the container in meters is 2.0066.
What is unitary method ?Unitary method is a mathematical way of first determining the value of a single unit then deriving the given unit from it.
According to the given question containers for international shipments measures 6 feet and 7 inches.
We know 1 feet is 12 inches.
∴ 6 feet is (12 × 6) = 72 inches.
So, 6 feet 7 inches is (72 + 7) inches which is 79 inches.
We know 1 inches is 0.0254 meter.
∴ 79 inches is ( 79 × 0.0254 ) meter which is

A swimming pool holds 2,640,000 quarts of water.
How many gallons does it hold?
Enter your answer as a number, like this: 42
Answer:
660,000 gallons.
Step-by-step explanation:
Quarts refers to a unit of measurement of volume of a fluid such as water. Quart is typically a standard unit in the British Imperial (imperial quarts) and United States of America (U.S) Customary systems (liquid and dry quarts) of measurement as a unit of volume or capacity.
Generally, there are three (3) types of quarts still in use today; dry quarts, imperial quarts and the liquid quarts.
A quart has the symbol "qt" and it's typically calculated as a quarter (¼) of a gallon.
Mathematically, it is given by the expression;
[tex] 1 \; Quart = 0.25 \; Gallon[/tex]
Therefore, [tex] Gallon = Quart * 0.25[/tex]
Given that the volume or capacity of the swimming pool is 2,640,000 quarts.
[tex] Gallon = 2,640,000 * 0.25[/tex]
[tex] Gallon = 660,000 [/tex]
Hence, the gallons of water of a swimming pool holding 2,640,000 quarts of water is 660,000 gallons.
I have three times as many cats as Alice but Bob has 7 less cats than me. In total we have 56 cats. How many cats do I have?
The number of cats that you have is; 27 cats
How to calculate algebra word problems?
Let the number of cats alice has be x.
Since you have thrice the amount of cats that alice has, then you have 3x cats.
Bob has 7 less cats than you. Thus, bob has; 3x - 7
If they have a total of 56 cats, then;
x + 3x - 7 + 3x = 56
7x - 7 = 56
7x = 56 + 7
7x = 63
x = 63/7
x = 9
Thus, number of cats you have = 3x = 3 * 9 = 27 cats
