The cosine of angle B is: cos(B) = AC / AB = 20/29
Define the Pythagorean Theorem?
The Pythagorean Theorem, a well-known geometric theorem that states that the sum of the squares of the legs of a right-angled triangle is equal to the square of the hypotenuse (the opposite side of the right angle) - that is, in familiar algebraic notation. , a2 + b2 = c2 .
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side to its hypotenuse. In this case, angle B is the angle we are interested in, and the adjacent side is side AC. Using the Pythagorean theorem, we find the length of side AC:
AC² = AB²+ BC²
AC² = 29² - 21²
AC² = 400
AC = 20
Therefore, the cosine of angle B is:
cos(B) = AC / AB = 20/29
Other trigonometric ratios of angle B can be found using the following formulas:
sin(B) = BC / AB = 21/29
tan(B) = BC / AC = 21/20
csc(B) = AB / BC = 29 / 21
sec(B) = AB / AC = 29/20
bed (B) = AC / BC = 20 / 21
Thus, the trigonometric ratios of angle B are:
sin(B) = 21/29
cos(B) = 20/29
tan(B) = 21/20
csc(B) = 29/21

1. A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 40 centimeters. The blueprint has a scale of three centimeters to four feet. What will be the actual area of the base of the fountain, in square feet, after it is built? Round your answer to the nearest tenth of a square foot.
the actual area of the base of the fountain, in square feet, after it is built is approximately 1.3 square feet (rounded to the nearest tenth of a square foot).
How to solve the question?
To find the actual area of the base of the fountain, we need to convert the measurements from the blueprint to the actual measurements.
First, we need to find the radius of the circular base. The diameter of the base is given as 40 centimeters on the blueprint, so the radius is half of that, or 20 centimeters.
Next, we need to convert the scale of the blueprint from centimeters to feet. The scale is given as three centimeters to four feet, which can be simplified to a ratio of 3:4. To convert from centimeters to feet, we need to multiply by a conversion factor of 1 foot/30.48 centimeters, since there are 30.48 centimeters in a foot.
So, to find the actual radius of the circular base in feet, we multiply the blueprint radius (20 centimeters) by the conversion factor:
20 centimeters * (1 foot/30.48 centimeters) = 0.656168 feet
Now that we have the actual radius of the circular base, we can find the actual area of the base. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Plugging in the actual radius we just found, we get:
A = π(0.656168 feet)^2 = 1.34977 square feet
Therefore, the actual area of the base of the fountain, in square feet, after it is built is approximately 1.3 square feet (rounded to the nearest tenth of a square foot).

Find sin(π/4). Round to 3 decimal places.
Step-by-step explanation:
sin (pi/4) = sqrt(2) / 2 = .707
you either just know this after a time or you can use a calculator (in RADIAN mode)
Answer:
sin(π/4) = sin(45°) = 0.707106781186548 ≈ 0.707 (rounded to 3 decimal places)
Step-by-step explanation:
here are the steps:
Convert π/4 to degrees: π/4 * (180/π) = 45°
Use the definition of sine to find the sine of 45°:sin(45°) = opposite/hypotenuse
In a right-angled triangle with an angle of 45°, the opposite and adjacent sides are equal, so we have:sin(45°) = opposite/hypotenuse = adjacent/hypotenuse = 1/√2
Rationalize the denominator by multiplying both the numerator and denominator by √2:sin(45°) = 1/√2 * √2/√2 = √2/2
Round to 3 decimal places: sin(45°) ≈ 0.707Therefore, sin(π/4) = sin(45°) = √2/2 ≈ 0.707 (rounded to 3 decimal places).

The polynomial function with the given properties is:[tex]f(x) = x^3 - 7x^2 + 9x - 17[/tex]
What do you mean by polynomial function?A polynomial function is a function that contains only non-negative integer powers or only positive integer exponents in the equation, such as a quadratic equation, a cubic equation, etc. For example, 2x + 5 is a polynomial whose exponent is 1.
Since the polynomial has real coefficients and one of its zeros is complex, the complex conjugate of 4+ i, which is 4-i, must also be zero. So the three zeros of the polynomial are -1, 4+i and 4-i. To form a polynomial with these zeros, we start by writing the factors of the polynomial:
(x + 1) (x - 4 - i) (x - 4 + i)
We can simplify this expression by multiplying the factors:

What do you mean by polynomial function?A polynomial function is a function that contains only non-negative integer powers or only positive integer exponents in the equation, such as a quadratic equation, a cubic equation, etc. For example, 2x + 5 is a polynomial whose exponent is 1.
If -1 is a zero of the polynomial function, then x+1 is a factor of the polynomial. Similarly, if 4+i is a zero, then 4-i is also a zero, because complex roots always occur in conjugate pairs. Therefore, (x+1) and (x - 4 - i)(x - 4 + i) = (x - 4)² + 1 are factors of the polynomial. We can then construct the polynomial function by multiplying these factors:
p(x) = A(x+1)(x - 4 - i)(x - 4 + i)
where A is a constant that we need to determine, and p(x) is the desired third-degree polynomial function.
To determine A, we can use the y-intercept given in the problem. The y-intercept is the value of p(0), so:
p(0) = A(0+1)(0 - 4 - i)(0 - 4 + i) = A(17+4i)
But we also know that p(0) = -17, so:
-17 = A(17+4i)
Solving for A:
A = -17/(17+4i) = (-17/5) + (68/5)i
Therefore, the polynomial function we seek is:
p(x) = [(-17/5) + (68/5)i](x+1)(x - 4 - i)(x - 4 + i)
Expanding the product and simplifying, we get:
p(x) = (-17/5)x³ + (34/5)x² + (33/5)x - 16
This is a third-degree polynomial with only real coefficients, -1 and 4+i are two of the zeros, and the y-intercept is -17.

How to evaluate the functions using piecewise function?
To evaluate the functions using piecewise function, we have to the condition they satisfy. That is:
For f(-9), x = -9. Thus, x≤ -6. So use f(x) = (-4/3)x - 4 to evaluate f(-9). That is:
f(-9) = (-4/3)*(-9) - 4
f(-9) = 8
For f(0), x = 0. Thus, -6 x ≤ 6. So use f(x) = (5/6)x + 2 to evaluate f(0). That is:
f(0) = (5/6)*0 + 2
f(0) = 2
For f(6), x = 6. Thus, -6 x ≤ 6. So use f(x) = (5/6)x + 2 to evaluate f(6). That is:
f(6) = (5/6)*6 + 2
f(6) = 7
For f(-6), f(x) = (-4/3)x - 4:
f(-6) = (-4/3)*(-6) - 4

A and C are linear because they are going in a straight line. E is going downwards, so it is decreasing. That leaves B and D, which have exponential growth.
HELP! Showing all work, solve for x and y and round to nearest tenth
Answer:
x = 67.4°
y = 22.6°
Step-by-step explanation:
The tangent ratio is a trigonometric ratio that relates the ratio of the length of the side opposite an angle in a right triangle to the length of the side adjacent to that angle.
[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]
Angle xThe side opposite angle x is 7.2, and the side adjacent angle x is 3.
Use the tangent trigonometric ratio to find the measure of angle x:
[tex]\begin{aligned}\tan(x)&=\dfrac{7.2}{3}\\x&=\tan^{-1}\left(\dfrac{7.2}{3}\right)\\x&=\vphantom{\dfrac12}67.380135...^{\circ}\\x&=67.4^{\circ}\;\sf (nearest\;tenth)\end{aligned}[/tex]
Therefore, x = 67.4°.
Angle yThe side opposite angle y is 3, and the side adjacent angle y is 7.2.
Use the tangent trigonometric ratio to find the measure of angle y:
[tex]\begin{aligned}\tan(y)&=\dfrac{3}{7.2}\\y&=\tan^{-1}\left(\dfrac{3}{7.2}\right)\\y&=\vphantom{\dfrac12}22.6198649...^{\circ}\\y&=22.6^{\circ}\;\sf (nearest\;tenth)\end{aligned}[/tex]
Therefore, y = 22.6°.
please help me solve the bonus question
Answer: a = 5 and k = 1/2
Step-by-step explanation:
We are given that the function is defined by:
f(x) = 16 + a(3^(kx))
We need to find the real numbers a and k such that f(0) = 21 and f(4) = 61. Using the given values of f(0) and f(4), we can form a system of two equations:
f(0) = 16 + a(3^(k(0))) = 21
f(4) = 16 + a(3^(k(4))) = 61
Simplifying the first equation, we get:
16 + a(3^0) = 21
16 + a = 21
a = 5
Substituting this value of a into the second equation, we get:
16 + 5(3^(4k)) = 61
5(3^(4k)) = 45
3^(4k) = 9
We know that 3^2 = 9, therefore
4k = 2
=> k = 2/4
=> k = 1/2
Therefore, the real numbers a and k that satisfy the given conditions are a = 5 and k = 1/2. So the function is:
f(x) = 16 + 5(3^(x/2))
The solution to the equation give us an approximate that x = 1.55.
What is the solution to the equation?To solve this equation, we can start by subtracting 4 from both sides to isolate the exponential term:
3.5^x + 4 - 4 = 11 - 4
This simplifies to:
3.5^x = 7
Next, we can take the logarithm of both sides with base 3.5 to eliminate the exponent:
log(3.5^x) = log(7)
Using the property of logarithms that log(a^b) = b*log(a), we can rewrite the left side as:
x*log(3.5) = log(7)
Now, we can solve for x by dividing both sides by log(3.5):
x = log(7) / log(3.5)
Plugging in the values, we get:
x = 0.84509804001 / 0.54406804435
x = 1.55329475566
x ≈ 1.55.

For each of the figures write an absolute value equation to satisfy the given solution set -5 and -1
the given solution set {-5, -1} can be obtained by substituting either of the possible solutions into the absolute value equation and verifying that it holds.
what is an equation ?
In mathematics, an equation is a statement that asserts the equality of two mathematical expressions. An equation typically consists of two expressions separated by an equal sign, with the expression on the left side of the equal sign equal to the expression on the right side of the equal sign.
In the given question,
To write an absolute value equation that satisfies a given solution set, we need to consider the definition of absolute value. The absolute value of a number is its distance from zero the number line. Therefore, an absolute value equation can be written as follows:
|expression| = distance
where the expression is the quantity whose absolute value is being taken, and distance is a non-negative value representing the distance from zero. The equation is satisfied if and only if the expression has a distance from zero that matches the given distance.
For the solution set {-5, -1}, we can write the following absolute value equations for the given figures:
A number line with -5 and -1 marked as solutions:
|x + 3| = 2
This equation is satisfied when x = -5 or x = -1, because |-5 + 3| = 2 and |-1 + 3| = 2.
A number line with -5 and -1 equidistant from zero:
|x| = 5
This equation is satisfied when x = -5 or x = 5, because |-5| = 5 and |5| = 5.
Note that for both figures, the given solution set {-5, -1} can be obtained by substituting either of the possible solutions into the absolute value equation and verifying that it holds.
