Convert the polar equation to a rectangular equation. \[ r=\frac{t 1}{1-\cos 0} \] Simplify the rectangular equakion by moving all of the terms to the ief side of the equation, and combining like term
Answers
The simplified rectangular equation for the given expression is x² + y² - t² / [1 - 2cos(θ)(1 - cos(θ))] = 0
Given polar equation is `r = t/(1-cos(θ))`
We need to convert the given polar equation into a rectangular equation using the following formulas:
x = rcos(θ)
y = rsin(θ)
r² = x² + y²
x² + y² = (rcos(θ))² + (rsin(θ))²
On substituting the value of r from the given polar equation, we get:
r = t/(1-cos(θ)) x² + y² = [(t/(1-cos(θ)))cos(θ)]² + [(t/(1-cos(θ)))sin(θ)]²
x² + y² = t² / (1 - 2cos(θ) + cos²(θ) + sin²(θ) - 2cos(θ) + cos²(θ))
x² + y² = t² / (1 - 2cos(θ) + 2cos²(θ))x² + y² = t² / [1 - 2cos(θ)(1 - cos(θ))]
Now we can simplify the rectangular equation by moving all of the terms to the left side of the equation and combining like terms.
x² + y² - t² / [1 - 2cos(θ)(1 - cos(θ))] = 0
This is the required rectangular equation of the given polar equation. Hence, the main answer isx² + y² - t² / [1 - 2cos(θ)(1 - cos(θ))] = 0.
Therefore, the simplified rectangular equation is x² + y² - t² / [1 - 2cos(θ)(1 - cos(θ))] = 0.

Grade Summary sin o cos tan o a tan a cotan sin h cos h tan h cotan h Degrees O Radians V
Answers
Therefore, each of the 10 braces exerts a force of approximately 6035.25 N.
To calculate the force exerted by each of the 10 braces, we need to consider the horizontal force exerted by the wind and the geometry of the wall and bracing.
Given:
Height of the wall (h) = 17.0 m
Length of the wall (l) = 11.0 m
Number of braces (n) = 10
Horizontal force exerted by the wind (F_w) = 645 N/m^2
First, let's calculate the total area of the wall:
Wall area (A) = h * l = 17.0 m * 11.0 m = 187.0 m^2
Since the net force from the wind acts at a height halfway up the wall, we can consider the force acting on the top half of the wall:
Force on the top half of the wall (F_t) = F_w * (A/2) = 645 N/m^2 * (187.0 m^2 / 2) = 60352.5 N
Next, let's calculate the force exerted by each brace:
Force exerted by each brace (F_brace) = F_t / n = 60352.5 N / 10 = 6035.25 N

Answers
2327 is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.
Given that,
TV viewers frequently doubt the validity of particular advertising. In an attempt to counter their critics, a large advertiser wants to determine the true proportion of consumers who believe what is depicted in ads. About 40% of individuals examined, according to preliminary studies, seem to believe what is depicted in advertisements.
We have to find what is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.
We know that,
Let
Population proportion (p)= 0.40
Margin of error = 2% = 0.02
Confidence level = 95% = 0.95
α = 1- 0.95 = 0.05
α/2 = 0.025
Let's find out the Z critical value using excel for the 95% confidence level,
Use the following excel command.
= ABS(NORMSINV(α/2))
= ABS(NORMSINV(0.025))
We will get, Z critical value = 2.17009
Sample size (n) = p(1-p)×(Zα/2)/E
n = 0.40(1-0.40)({2.17009}÷{0.05})²
Sample size (n) = 2327
Therefore, 2327 is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.

The monthly water charge for a farmer based on his consumption can be calculated using this function:
f(x)= {5.50 + 0.50x
{8.00 + 1.00 (x−5)
if 0 ≤ x < 5
if x > 5 where x is every 100 gallons of water consumed.
Using limits, find the bill that a farmer can expect to pay if he consumes 500 gallons of water. Also, check whether there is a jump in the pricing structure if consumption exceeds 500 gallons.
Answers
The function for calculating the monthly water charge for a farmer based on his consumption is given by:
f(x) = {5.50 + 0.50x, if 0 ≤ x < 5{8.00 + 1.00 (x−5),
if x > 5where x is every 100 gallons of water consumed.
The amount of water consumed by the farmer is given as 500 gallons.
We need to find out the monthly bill that the farmer can expect to pay.
Using limits, we can calculate the monthly bill as follows:
For 0 ≤ x < 5, f(x) = 5.50 + 0.50x
Using limits, f(5) = lim {f(x)}
as x approaches 5 from the left= lim {5.50 + 0.50x}
as x approaches 5 from the left= 5.50 + 0.50(5)= 8.00
For x > 5, f(x) = 8.00 + 1.00 (x−5)
Therefore, the monthly bill for consuming 500 gallons of water is given by:
For 0 ≤ x < 5, the bill = f(x) = 5.50 + 0.50(5) = $8.00
For x > 5,
the bill = f(x) = 8.00 + 1.00 (x−5) = 8.00 + 1.00 (500/100 - 5) = $13.00
Therefore, the farmer can expect to pay a monthly bill of $13.00 if he consumes 500 gallons of water. Yes, there is a jump in the pricing structure if the consumption exceeds 500 gallons as the price increases from $8.00 to $13.00 per month.

4. Give an equation of the surface of revolution generated by revolving x = (1/z )^z about the z-axis.
Answers
The equation of the surface of revolution generated by revolving x = (1/z)^z about the z-axis is x = e^(-y).
To find the equation of the surface of revolution, we start with the parametric equation x = (1/z)^z, y = t, z = t. We eliminate the parameter t by substituting z for t in the equation x = (1/z)^z. Simplifying further, we obtain x = e^(-y).
This equation represents the surface of revolution generated by revolving the curve x = (1/z)^z about the z-axis. The exponentiation by e^(-y) signifies that the x-coordinate changes exponentially as the y-coordinate varies.
Therefore, as we revolve the curve around the z-axis, it forms a surface with an exponential decay in the x-direction. Hence, the equation x = e^(-y) describes the surface of revolution.

Answers
Step-by-step explanation:
Let's call the number of girls in the school "g". We know that there are 1000 boys, so the total number of students is 1000 + g.
The problem states that 48% of the total number of students were successful in the examination. Therefore, we can write an equation:
0.48(1000 + g) = 0.5(1000) + 0.4(g)
Simplifying and solving for g:
480 + 0.48g = 500 + 0.4g
0.08g = 20
g = 250
Therefore, the number of girls in the school is 250.
Answer:
250
Step-by-step explanation:
Hi dear,
Firstly, let the girls be G
1000 + G = Total number of students
50% of boy = 1000 × 0.5 = 500
40% of girls = G × 0.4 = 0.4G
0.48 • (1000 + G) = 480 + 0.48G
480 + 0.48G = 500 + 0.4G
Collect Like Terms
0.48G - 0.4G = 500 - 480
0.08G = 20
G = 20/0.08
G = 250

Step-by-step explanation:
Let's set up a systems of equation because we have two different values involved: first-class and coach.
f + c = 12
350f + 1080c = 6390
For ease of the equation, let's use the first equation to isolate a variable and plug it into the second one. We'll isolate f:
f = 12 - c
350(12 - c) + 1080c = 6390
c = 3
Now, plug in 3 for the first equation, and f = 9.
