simplify cos x csc x
Answer:
cot(x)
Step-by-step explanation:
csc(x) = 1/sin(x)
cos(x)*csc(x) = cos(x)*1/sin(x)
cos(x)*csc(x) = cos(x)/sin(x)
cos(x)*csc(x) = cot(x)
----
abbreviations
csc = cosecant
cos = cosine
sin = sine
cot = cotangent
To simplify cos x csc x, we can replace csc x with 1/sin x based on the trigonometric identity. This will give us cos x/sin x, which is the same as cot x based on the trig identities.
Explanation:The question is asking us to simplify the expression cos x csc x. To do this, we can use the trigonometric identity sin = 1/csc, which tells us what csc x is in terms of sin x.
So if that is the case, we can rewrite csc x as 1/sin x and replace csc x in the original expression giving us cos x * (1/sin x) or equivalently cos x/sin x.
And if we look at our trigonometric identities again, we can find that cos x/sin x is the same as cot x, our final simplified expression.

Find the linear approximation for f(x) = 12x3 + 3x2 + x + 2 at x= 1.
Answer:
y = 43x − 25
Step-by-step explanation:
Evaluate the function at x=1:
f(x) = 12x³ + 3x² + x + 2
f(1) = 12 + 3 + 1 + 2
f(1) = 18
Find the slope of the tangent line at x=1:
f'(x) = 36x² + 6x + 1
f'(1) = 36 + 6 + 1
f'(1) = 43
Point-slope form:
y − y₀ = m (x − x₀)
y − 18 = 43 (x − 1)
Convert to slope-intercept form:
y − 18 = 43x − 43
y = 43x − 25

To find the linear approximation for the function f(x) = 12x^3 + 3x^2 + x + 2 at x = 1, we can use the equation for the linear approximation. First, we need to find the derivative of the function and then plug in the values into the formula. The linear approximation is f(1).
Explanation:To find the linear approximation for the function f(x) = 12x^3 + 3x^2 + x + 2 at x = 1, we can use the equation for the linear approximation:
() ≈ () + '()( − )
First, we need to find '(), which is the derivative of the function. Taking the derivative of f(x) gives us:
'() = 36^2 + 6 + 1
Next, we plug in x = 1 into the first equation:
(1) ≈ (1) + '(1)(1 − 1)
Simplifying, we have:
(1) ≈ (1)
So, the linear approximation for f(x) at x = 1 is f(1).

(8.) 12.5%
How do u write 12.5 percent as a fraction
Answer: 1/8
Step-by-step explanation: To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100.
So here, 12.5% can be written as the ratio 12.5 to 100 or 12.5/100.
To write 12.5/100 in lowest terms, first multiply the numerator and the denominator by 10 to get rid of the decimal. When we do this, we get the fraction 125/1000.
Now, we divide the numerator and the denominator of 125/1000 by the greatest common factor of 125 and 1,000 which is 125 and we end up with the equivalent fraction which is 1/8.
Therefore, 12.5% is equivalent to 1/8.

Find the y intersept of
y=logbase (b)(a-k) based on the constants b and k ?
Answer:
[tex](0, log_{b}(-k)), k < 0[/tex]
Step-by-step explanation:
[tex]y = \log_{b}(a - k)[/tex]
To find the y-intercept, set a = 0 and solve for y.
[tex]y = \log_{b}(0 - k)\\y = \log_{b}(-k)[/tex]
This equation is undefined for k ≥ 0.
There is a y-intercept only if k < 0. Only then can the argument of the log function be positive.
The y-intercept is at
[tex]\mathbf{(0, log_{b}(-k)), k < 0}[/tex]
For example, if b = 2 and k = -3, log₂(3) = 1.585
The intercept is at (0, 1.585).

The equation S = -16t2 + 34t + 184 models the height of a ball that is thrown upward from the roof of a 184 foot building and falls to the street below. In this equation S is the height in feet of the ball above the ground and t is the time in seconds the ball has traveled. According to this model, how many seconds did it take the ball to reach a height of 91 feet? (round to 1 decimal place)
Answer:
t=1.6
Step-by-step explanation:
If the equation [tex]S=-16t^2+34t+184[/tex] models the height of a ball above the ground, where t is time the ball travelled.If the height of the ball above the ground is S=91 instead of 184, then the time the ball should take to get to the ground comes from the expression above: [tex]S=-16t^2+34t+91[/tex] (because now we want to know how much time does it takes to reach the ground if it is thrown from 91 foot, not 184). Then, to know when the ball reaches the floor, we must equal the equation to zero [tex]-16t^2+34t+91=0[/tex] (because when the equation is zero, the height of the ball is zero, which means it is in the ground).To obtain the value of t in the expression [tex]-16t^2+34t+91=0[/tex] , we can apply the well known formula [tex]t=\frac{-b(+-)\sqrt{b^2-4ac} }{2a}[/tex], where a is the coefficient that accompanies the quadratic term (in this case a=16), b is the coefficient that accompanies the linear term (b=34 in this case), and c is the constant coefficient (c=91).Because time is always possitive, we only retain the possitive value for t that solves the equation:[tex]\frac{-34(+-)\sqrt{34^2-4\times(-16)\times93} }{2\times16}[/tex].

Find four consecutive numbers whose sum equals 218
Answer: 53, 54, 55, and 56
Step-by-step explanation: This problem states that the sum of 4 consecutive numbers is 218 and it asks us to find the numbers.
4 consecutive numbers can be represented as followed.
X ⇒ first number
X + 1 ⇒ second number
X + 2 ⇒ third number
X + 3 ⇒ fourth number
Since the sum of our 4 consecutive numbers is 218, we can set up an equation to represent this.
X + X + 1 + X + 2 + X + 3 = 218
On the left side of the equation, we can combine our x's and our numbers.
4x + 6 = 218
-6 -6 ← subtract 6 from both sides of the equation
4x = 212
÷4 ÷4 ← divide both sides of the equation by 4
X = 53
X ⇒ first number = 53
X + 1 ⇒ second number = 54
X + 2 ⇒ third number = 55
X + 3 ⇒ fourth number = 56
Therefore, our 4 consecutive numbers are 53, 54, 55, and 56.
How do I find the slope, y-intercept, and coordinates of (-1,7) (0,5)?
Answer:
The slope for the given points is - 2 , and y- intercept is 5
Step-by-step explanation:
Given points as :
( - 1 , 7 ) and ( 0 , 5 )
Now slope of line in points form as
Slope = m = [tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]
or, m = [tex]\dfrac{5 - 7}{0 + 1}[/tex]
or, m = - 2
so, Slope of line is - 2
Now equation of line is given as
y - [tex]y_1[/tex] = m × ( x - [tex]x_1[/tex] )
or, y - 7 = ( - 2 ) × ( x + 1)
or, y - 7 = - 2 x - 2
Or, equation of line is
y = - 2 x + 5
Now, for y - intercept , x = 0
So, from line equation
y = - 2 × 0 + 5
Or, y = 0 + 5
∴ y = 5
Hence The slope for the given points is - 2 , and y- intercept is 5 Answer

At a sale this week, a sofa is being sold for $244.80. This is a 64% Discount from the original price. What is the original price?
Answer:
680$
Step-by-step explanation:
If this is a 64% discount, the price 244.80 is 36% of the original price
244.8 = 36% -Divide by 36 on both sides
6.8 = 1% - Times by a hundred
680 = 100%
The original price is 680$
To find the original price of the sofa given a 64% discount, divide the sale price by the discount percentage and subtract it from 100%.
Explanation:To find the original price, we need to determine what the discount percentage represents in terms of the original price. Since the sale price is 64% of the original price, the discount is 100% - 64% = 36%. Let's represent the original price as x:
36% of x = $ 244.80
To solve this equation, we can convert 36% to the decimal form by dividing it by 100: 36/100 = 0.36. Now we can solve for x:
0.36x = $ 244.80
Dividing both sides of the equation by 0.36, we get:
x = $ 244.80 / 0.36 = $ 680
Therefore, the original price of the sofa was $ 680.

Write the equation of the line in slope intercept form that contains the point (-2,-1) and is perpendicular to the graph of y=-2x-3
Answer:
y = -0.5x -2
Step-by-step explanation:
We have to find a line perpendicular to the line y = -2x -3.
Let the required line will have slope m so ,
-2m = 1
m = -0.5.
So, the required line will have the slope -0.5.
Now, let the line be y = -0.5x + c.
This line is passing through (-2,-1), So putting this point in the line we will get
-1 = 1 + c
c = -2 .
So, the required line is
y = -0.5x -2.
