Using right triangle relations, we will get:
tan(B) = 1.05sin(B) = 0.735cos(B) = 0.7How to find the value of the trigonometric equations?
We assume that bot triangles are equivalent, then the angle B will be the same as the angle Z.
Now remember the relations:
tan(θ) = (opposite cathetus)/(adjacent cathetus).sin(θ) = (opposite cathetus)/(hypotenuse)cos(θ) = (adjacent cathetus)/(hypotenuse).If we step on angle B, we have:
opposite cathetus = 29.4adjacent cathetus = 28hypotenuse = 40.6Replacing that, we get:

The correct answer is Option C. The graph represents the function f (x) = StartFraction 1 Over x EndFraction minus 1 is On a coordinate plane, a hyperbola is shown. One curve opens up and to the right in quadrant 1, and the other curve opens down and to the left in quadrant 3. A vertical asymptote is at x = negative 1, and the horizontal asymptote is at y = 0.
On a coordinate plane, the graph of a hyperbola is shown.
In quadrant 1, one curve opens up and to the right, while in quadrant 3, the other curve opens down and to the left.
The vertical asymptote is at x = -1, and the horizontal asymptote is at y = 0. This hyperbola is symmetrical across both the x and y axes.
The function f(x) = 1/x - 1 has a vertical asymptote at x = 0 because the denominator approaches zero as x approaches zero.
A fraction with a denominator of zero cannot exist.
The horizontal asymptote of this function is y = -1 because as x approaches infinity or negative infinity, f(x) approaches -1.

if fx and gx are inverse functions of each other
Answers
The functions f(x) = (x + 3)/2 and g(x) = 2x - 3 are inverse functions of each other.
The function is the mathematical statement that shows the relationship between one variable and other variable. If one variable is independent variable then other variable is dependent variable.
The functions are
f(x) = (x + 3)/2
g(x) = 2x - 3
The value of f(g(x)) = ((2x-3) + 3) / 2

= x
The value of g(f(x)) = 2( (x+3)/2) - 3

The radius of a circle is 20 in. Find its circumference in terms of π
Answers
Answer:
40π inches
Step-by-step explanation:
What is the formula for the circumference of a circle?
The formula for the circumference of a circle is:
C = 2πr(where C is the circumference and r is the radius)
If the radius of the circle is 20 inches, then its circumference in terms of π would be:
C = 2π × 20 = 40π inchesTherefore, the circumference of a circle when the radius is 20in is 40π inches.
Answer:
C = 40π
Step-by-step explanation:
To calculate the circumference of a circle, we will use the formula
C = 2πr
And we're asked to find C in terms of pi.
So all I need to do is plug in 20 for the radius, and then multiply.
I plug in 20 for the radius, r: C = 2π × 20
Multiply: C = 40π
Therefore, C = 40π.

Therefore, use 2n – 1 instead of 2n +1.C= ___
Answers
Coefficient Cn is determined by Cn = 1/2 ∫[0,2] (x+2)yn(x) dx
To find the coefficients Cn of the eigenfunction expansion of a function f(x), f(x) must be expanded with the eigenfunction yn(x). The expansion of f(x) with respect to the eigenfunction yn(x) is given by
f(x) = Σ[∞], n=1 cnyn(x)
To find the coefficient cn, we need to compute the dot product of f(x) and yn(x).
cn = (f,yn) = ∫[0,4]f(x)yn(x)dx
Since the eigenfunctions yn(x) are orthonormal, the scalar product is given by
cn = ∫[0,4]f(x)yn(x)dx = ∫[0,2]f(x)yn(x)dx + ∫[2,4]f(x)yn(x)dx
Since f(x) = 2/2 x for x in [0,2] and f(x) = 2 for x in [2,4], compute the coefficient cn as I can do it.
cn = ∫[0,2](2/2x)yn(x)dx + ∫[2,4](2)yn(x)dx
= ∫[0,2]xyn(x)dx + ∫[2,4]2yn(x)dx
= 1/2 ∫[0,2] (xyn(x) + 2yn(x)) dx
= 1/2 ∫[0,2] (x+2)yn(x) dx
Therefore, the coefficient Cn is given by
Cn = 1/2 ∫[0,2] (x+2)yn(x) dx

A random sample of 28 fields of spring wheat has a mean yield of 44.7 bushels per acre and standard deviation of 6.96 bushels per acre. Determine the 95% confidence interval for the true mean yield. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places
Answers
Answer:
\(44.7-2.052\frac{6.96}{\sqrt{28}}=42.001\)
\(44.7+2.052\frac{6.96}{\sqrt{28}}=47.399\)
And the confidence interval would be between 42.001 and 47.399
Step-by-step explanation:
Information given
\(\bar X=44.7\) represent the sample mean for the sample
\(\mu\) population mean
s=6.96 represent the sample standard deviation
n=28 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
\(\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}\) (1)
The degrees of freedom are given by:
\(df=n-1=28-1=27\)
The Confidence interval is 0.95 or 95%, the significance is \(\alpha=0.05\) and \(\alpha/2 =0.025\),the critical value for this case would be \(t_{\alpha/2}=2.052\)
And replacing we got:
\(44.7-2.052\frac{6.96}{\sqrt{28}}=42.001\)
\(44.7+2.052\frac{6.96}{\sqrt{28}}=47.399\)
And the confidence interval would be between 42.001 and 47.399

In a sample of 560 adults, 336 had children. Construct a 95% confidence interval for the true population proportion of adults with children.
Give your answers as decimals, to three places
< p <
What is the expected value of �?
Answers
The confidence interval is 0.559 < p < 0.641 and expected value is 0.600
Confidence IntervalTo construct a confidence interval for the true population proportion, we can use the formula:
p ± Z * √((p × (1 - p)) / n)
Where:
p = sample proportion (336/560)
Z = critical value for the desired confidence level
95% confidence = Z-value of approximately 1.96
n = 560
Let's calculate the confidence interval:
p = 336/560 ≈ 0.600
Z ≈ 1.96 (for a 95% confidence level)
n = 560
Plugging these values into the formula:
p ± Z × √((p × (1 - p)) / n)
0.600 ± 1.96 × √((0.600 × (1 - 0.600)) / 560)
0.600 ± 1.96 × √((0.240) / 560)
0.600 ± 1.96 × √(0.0004285714)
0.600 ± 1.96 × 0.020709611
0.600 ± 0.040564459
The confidence interval is:
0.559 < p < 0.641
Therefore, the 95% confidence interval for the true population proportion of adults with children is 0.559 < p < 0.641.

An engineer traveled 140 mi by car and then an additional 750 mi by plane. The rate of the plane was three times the rate of the car. The total trip took 6 h. Find the rate of the car.
Answers
The rate of car is 35 mph.
Given that engineer traveled 140 mi by car and then an additional 750 mi by plane. The rate of the plane was three times the rate of the car.
Let c be the rate of wind.
215 + c = rate of plane with wind
215 - c = rate of plane against wind
Therefore, the travel time =distance/rate
⇒ 750/(215+c) = 540/(215-c)
Cross multiplying we get,
540(215+c) = 750(215-c)
116100+540c = 161250-750c

P(X=0) is 0.0046, which means that there is a 0.0046 probability that exactly 0 employees will be absent per day.Similarly,
P(X=1) is 0.0248, which means that there is a 0.0248 probability that exactly 1 employee will be absent per day. P(X=2) is 0.3098, which means that there is a 0.3098 probability that exactly 2 employees will be absent per day, and so on.When finding probabilities for a range of X values, you need to add up the individual probabilities of all the values in the range. For example, if you are looking for
P(2≤X≤5), then you need to add the individual probabilities for X = 2, 3, 4, and 5, which is 0.3098 + 0.3399 + 0.219 + 0.0798 = 0.5945. Similarly, if you are looking for P(X>5), then you need to add the individual probabilities for X = 6 and 7, which is 0.019 + 0.0031 = 0.0221. Finally, if you are looking for P(X<4), then you need to add the individual probabilities for X = 0, 1, 2, and 3, which is 0.0046 + 0.0248 + 0.3098 + 0.3399 = 0.3614.Learn more about probabilities:
