For two parametric equations, x = cos(t)− sin(t) ; y = cos(t) + sin(t) ; 0≤t≤2π

a) Cartesian equation for the parametric curve is represented by x² + y² = 2.

b) The sketch for this parametric curve, with arrows in the direction of curve tracing is present above figure.

A parametric curve in the x-t plane has the equations x=x(t), y=y(t). The curve associates a point of the plane (x,y) to a value of the parameter t. The rectangular form of the curve can be determined by eliminating the parameter t, i.e. determine the parameter in one equation and Substituting this value in the other equation. We have the following parametric equations,

x = cos⁡t - sin⁡ty = cos⁡(t)+ sin⁡t, 0 ≤ t ≤ 2π

(a) we have to eliminate parameter t to determine a cartesian equation for the parametric curve, use x²+ y² = (cos⁡(t) − sin⁡(t))²+ (cos⁡(t) + sin⁡(t))²

=> x² +y² = cos²t + sin²t - 2cos⁡t sin⁡t + cos²t + sin²t + 2cos⁡t sin⁡t

=> x² + y² = 2 ( sin²t + cos²t) = 2

which represents a circle curve centered at the origin and having radius √2.

(b) A sketch of this parametric curve is shown above figure and arrows are used to indicate the direction of curve trace.

the volume of the basketball is approximately 490 cubic inches. we can get this answer by using volume formula of volume

what is approximately ?

"Approximately" means almost, but not exactly. It is used to indicate that a value or quantity is very close to the true or exact value, but there may be a small difference or error. In mathematical terms, an approximate value is an estimate or a rounded value that is used

In the given question,

To find the volume of the basketball, we first need to find its radius.

Circumference of a sphere = 2πr

29.516 = 2 * 3.14 * r

r = 29.516 / (2 * 3.14) ≈ 4.7 inches (rounded to one decimal place)

Now, we can use the formula for the volume of a sphere:

Volume of sphere = (4/3) * π * r^3

Volume of basketball = (4/3) * 3.14 * (4.7)^3

Volume of basketball ≈ 490 cubic inches (rounded to the nearest whole number)

Therefore, the volume of the basketball is approximately 490 cubic inches..

Option C is correct. No, the least value is smaller than the critical value.

Null hypothesis (H₀): The average first-year teacher salary is $52,000.

Alternative hypothesis (Ha): The average first-year teacher salary is not $52,000.

The significance level is 5% (or 0.05), which means we will reject the null hypothesis if the probability of obtaining the observed result is less than 5%.

Calculate the standard error of the mean:

Standard Error = Standard Deviation / √n

where n is the number of samples (n = 25 in this case).

Standard Error = $1500 / √25

= $1500 / 5

= $300

Now, perform the hypothesis test using a t-test since the sample size is relatively small (n < 30) and the population standard deviation is unknown.

t-score = (Sample Mean - Population Mean) / Standard Error

t-score = ($52,525 - $52,000) / $300

t-score = $525 / $300

t-score = 1.75

To find the critical value at a 5% significance level with 24 degrees of freedom (n - 1), we can consult a t-table. At a 5% significance level (two-tailed test), the critical t-value is approximately ±2.064.

Since the calculated t-score (1.75) is not greater than the critical t-value (2.064), we fail to reject the null hypothesis.

Therefore, option C is correct. No, the least value is smaller than the critical value.

Derivative of y w.r.t t is dy/dt = 16 at x = -1.

We need to find dy/dt at x = -1, given y = -2x² + 4 and dx/dt = 4.

Step 1: Differentiate y with respect to x.
Since y = -2x² + 4, we have:

dy/dx = -4x

Step 2: Substitute x = -1 into the dy/dx equation.
When x = -1, we get:

dy/dx = -4(-1) = 4

Step 3: Use the Chain Rule to find dy/dt.
The Chain Rule states that dy/dt = (dy/dx)(dx/dt). We know dy/dx = 4 and dx/dt = 4, so we have:

dy/dt = (4)(4) = 16

Thus, dy/dt = 16 at x = -1.

Therefore, the solutions of the equation in the interval [0, 2) are: x = π/6, -π/6 (in radians) or x = 30°, -30° (in degrees). Note that the solutions are listed in ascending order.

The equation is:

sec(x) = 2√3/3

First, we can find the values of x for which sec(x) = 2√3/3. Recall that sec(x) = 1/cos(x), so we have:

1/cos(x) = 2√3/3

Multiplying both sides by cos(x), we get:

1 = 2√3/3 cos(x)

cos(x) = 3/(2√3) = √3/2

Now, we can use the unit circle to find the solutions of the equation in the interval [0, 2).

cos(x) = √3/2 when x is π/6 or 11π/6 (in radians), or 30° or 330° (in degrees), since these are the angles in the unit circle where the x-coordinate is √3/2.

However, we need to make sure that these solutions are in the interval [0, 2). Since the period of sec(x) is 2π, we can add or subtract 2π to any solution to get another solution. Therefore, we need to find the solutions in the interval [0, 2π) that correspond to the solutions we found above.

π/6 is already in the interval [0, 2π), so it is a solution in the interval [0, 2). To find the other solution in the interval [0, 2), we can add 2π to 11π/6:

11π/6 + 2π = 23π/6

23π/6 is not in the interval [0, 2), so we need to subtract 2π instead:

11π/6 - 2π = -π/6

-π/6 is in the interval [0, 2), so it is also a solution in the interval [0, 2).

Therefore, the solutions of the equation in the interval [0, 2) are:

x = π/6, -π/6 (in radians) or x = 30°, -30° (in degrees)

If you are earning $12.50/hr in a part-time job, then your gross "base-pay" after deductions is $253.48.

Your base pay is $12.50/hr and you worked for 18 hours, so the base pay would be:

⇒ $12.50/hr × 18 hrs = $225;

The tips are $4.60/hr on average, so the "total-tips" earned would be:

⇒ $4.60/hr × 18 hrs = $82.80;

To calculate the "total-deductions", we first find the total percentage deducted, which is the sum of FICA and Federal Tax Withholding:

⇒ 7.65% + 10% = 17.65%,

To find the total amount deducted, we multiply the total percentage deducted by the "base-pay" + "tips";

⇒ 17.65% x ($225 + $82.80) = $54.32,

So the pay, before any deductions, is the sum of "base-pay" and "tips";

⇒ $225 + $82.80 = $307.80;

To find the "net-pay", we subtract "total-deductions" from pay;

Answer:

Step-by-step explanation:

Since sin(a) is negative and a is in the third quadrant, we can use the Pythagorean identity to find cos(a):

[tex]cos^2(a) + sin^2(a) = 1[/tex]

[tex]cos^2(a) + (-4/5)^2 = 1[/tex]

[tex]cos^2(a) = 9/25[/tex]

cos(a) = -3/5 (since a is in the third quadrant)

Similarly, since sec(B) = 5/3, we can use the definition of secant to find cos(B):

sec(B) = 1/cos(B) = 5/3

cos(B) = 3/5

(a) To find sin(a + B), we can use the sum formula for sine:

sin(a + B) = sin(a) cos(B) + cos(a) sin(B)

= (-4/5)(3/5) + (-3/5)(4/5)

= -12/25 - 12/25

= -24/25

(b) To find tan(a + B), we can use the sum formula for tangent:

tan(a + B) = (tan(a) + tan(B)) / (1 - tan(a) tan(B))

To find tan(a), we can use the identity: [tex]tan^2(a) + 1 = sec^2(a)[/tex]

[tex]tan^2(a) = sec^2(a) - 1 = (5/3)^2 - 1 = 16/9[/tex]

tan(a) = -4/3 (since a is in the third quadrant)

To find tan(B), we can use the identity: tan(B) = sin(B) / cos(B) = 4/3

Plugging these values into the formula for tan(a + B), we get:

tan(a + B) = (-4/3 + 4/3) / (1 + (-4/3)(4/3))

= 0 / (1 - 16/9)

= 0

(c) To determine the quadrant containing a + B, we need to consider the signs of sin(a + B) and cos(a + B).

From part (a), we know that sin(a + B) is negative. To determine the sign of cos(a + B), we can use the Pythagorean identity:

[tex]sin^2(a + B) + cos^2(a + B) = 1[/tex]

Substituting sin(a + B) = -24/25, we get:

[tex](-24/25)^2 + cos^2(a + B) = 1[/tex]

[tex]cos^2(a + B) = 1 - (-24/25)^2[/tex]

cos(a + B) = ±7/25

Since cos(a + B) is positive in the first and fourth quadrants, and negative in the second and third quadrants, we can conclude that a + B is in the third quadrant, since cos(a + B) is negative and sin(a + B) is negative.
