The hypotenuse of the right triangle ABC shown below is 17 feet long. The cosine of angle C is 35. How many feet long is the segment AC?
Length of the segment AC is 14 feet
What is Trigonometric function?In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
Given,
Length of the hypotenuse = 17 feet
Angle of C =35 degrees
We know that,
Cos θ = Adjacent side / Hypotenuse
cos 35 = [tex]\frac{x}{17}[/tex]
x= [tex]17(cos 35)[/tex]
x= 13.9 ≅ 14 feet
Hence, the length of the segment AC is 14 feet

Find an equation for the nth term of the arithmetic sequence.
-17, -12, -7, -2, ...
Answer Choices
A: an = -17 + 5(n + 2)
B: an = -17 + 5(n + 1)
C: an = -17 + 5(n - 1)
D: an = -17 x 5(n - 1)
The equation for the nth term of the given arithmetic sequence is an = -17 + 5(n - 1), which matches answer choice C.
The given sequence is an arithmetic sequence, where each term increases by a common difference. To find the equation for the nth term (an), you start with the first term (a1 = -17) and add the common difference (d = 5) multiplied by (n - 1), since the first term is already in place.
A correct formula for an arithmetic sequence is an = a1 + (n - 1)d. Applying this to the given sequence, we have an = -17 + (n - 1)5. Simplifying this expression gives us an = -17 + 5n - 5, which further simplifies to an = 5n - 22. Thus, the correct answer is an = -17 + 5(n - 1), which corresponds to answer choice C.

Answer:
A) [tex]25x^2y^{22}[/tex]
Step-by-step explanation:
The given expression is [tex](5xy^{5})^2 . (y^3)^4[/tex]
Here we have to use exponent rules and simplify the expression.
Power rule : [tex](a^m)^n = a^{mn}[/tex]
Using the above rule, we can write
[tex](5xy^{5} )^2 = 5^2.x^2.y^{5*2}[/tex]
= [tex]25.x^2.y^10[/tex]
Again using the power rule
[tex](y^{3} )^4 = y^12[/tex]
Now we have to put together this expression, we get
= [tex]25.x^2.y^{10} .y^{12}[/tex]
Now we have to use product rule.
Product rule: [tex]a^m . a^n = a^{m + n}[/tex]
Using this rule, we can simplify further

Find h(x, y) = g(f(x, y)). g(t) = t + ln(t), f(x, y) = 4 − xy 2 + x2y2 h(x, y) =
The function h(x, y) is given by the composition of the functions g(t) and f(x, y). With the given expressions for f and g, the function h(x, y) = g(f(x, y)) equals to (4 - xy^2 + x^2y^2) + ln(4 - xy^2 + x^2y^2).
Explanation:The question asks to find the function h(x, y) from the functions g(t) and f(x, y), where g(t) = t + ln(t), and f(x, y) = 4 − xy^2+ x^2y^2. To begin with, it is necessary to substitute f(x, y) in place of 't' in function g which is g(f(x, y)), since we have h(x, y) = g(f(x, y)).
Performing the substitution, we obtain:
h(x, y) = g(f(x, y)) = (4 - xy^2 + x^2y^2) + ln(4 - xy^2 + x^2y^2).
This is your final function h in terms of x and y.

Titus had 1/2 can of paint. He used 2/3 to paint a tabletop. What fraction of a full can of paint did Titus use?
Titus had half a can of paint and used two-thirds of it, which means he used (1/2) * (2/3) = 2/6, which simplifies to 1/3 of a full can of paint.
Explanation:The student is asking about how to calculate the fraction of a full can of paint Titus used given that he had half a can and used two-thirds of it. To find out what fraction of the full can he used, you need to perform a multiplication of the two fractions.
Here is the step-by-step calculation:
Write down the fractions: 1/2 (half a can of paint Titus had) and 2/3 (the fraction he used).Multiply these two fractions: (1/2) \\times\ (2/3)Simplify the multiplication: The numerators are multiplied together and the denominators are multiplied together: (1 \\times\ 2)/(2 \\times\ 3) = 2/6Reduce the fraction, if possible: 2/6 can be simplified to 1/3 by dividing both numerator and denominator by 2.Therefore, Titus used 1/3 of a full can of paint.

Find the orbital period (in years) of an asteroid whose average distance from the sun is 5 au.
Final answer:
To find the orbital period of an asteroid at 5 AU, apply Kepler's Third Law, resulting in approximately 11.18 years.
Explanation:
The question asks to find the orbital period of an asteroid with an average distance of 5 astronomical units (AU) from the Sun. We can use Kepler's Third Law of Planetary Motion, which states that the square of the orbital period (T, in years) is proportional to the cube of the average distance from the Sun (a, in astronomical units) for any object orbiting the Sun, expressed as-
[tex]T^2 = a^3[/tex]
Applying the formula for the asteroid in question:
Identify the average distance from the Sun, which is given as 5 AU.Calculate the cube of this distance: 53 = 125.Find the square root to determine the orbital period: √125 ≈ 11.18 years.Therefore, the orbital period of the asteroid is approximately 11.18 years.
Find the perimeter of a square measuring 5.35cm on a side
The perimeter of a square measuring 5.35 cm on a side is 21.4 cm
Further explanationTo solve the above questions, we need to recall some of the formulas as follows:
Area of Square = (Length of Side)²
Perimeter of Square = 4 × (Length of Side)
Area of Rectangle = Length × Width
Perimeter of Rectangle = 2 × ( Length + Width )
Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Rhombus = 4 × ( Length of Side )
Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

34+x=46;x=12 is this problem a solution
Final answer:
The solution x=12 is correct for the problem 34+x=46, as substituting x=12 into the original equation results in 46, matching the right side. Verification by substitution is a common practice to confirm the accuracy of solutions, particularly in the case of equations with two solutions.
Explanation:
The problem provided is 34+x=46; you have also provided that x=12 is the solution. To verify if x=12 is the correct solution, we substitute x=12 into the original equation: 34+12=46. Upon calculating, 34+12 equals 46, which is indeed the right side of the equation, confirming that the solution x=12 is correct.
Moreover, in general mathematical practice, checking solutions by substituting them back into the original equation is a reliable method for verification. If a problem has two solutions, as some quadratic equations do, both solutions should be checked in this way to ensure that each solution satisfies the original equation, indicating that both are correct. For example, if we have a quadratic equation like 2x²-8=0, solving it would give us two possible values for x that can be substituted back into the equation to verify if the identity holds true for both solutions.
Final answer:
The given solution x=12 for the equation 34+x=46 is correct because when substituted back into the original equation, it results in an identity, confirming the solution's validity.
Explanation:
In mathematics, particularly in algebra, when we have an equation such as 34 + x = 46, and we are given a solution, in this case x=12, we can verify its correctness by substituting the value back into the original equation. If the equation simplifies to an identity, which is an equation that always holds true like 6 = 6, then the given solution is correct. To check if x=12 is a solution for the original problem, we perform the substitution:
34 + 12 = 46
After the substitution, the equation simplifies to:
46 = 46
This results in an identity, confirming that the given solution x=12 is indeed correct.
This process is similar to checking solutions for other types of equations, such as linear, quadratic, or higher-degree polynomials. Whether a problem has a single solution like in this case, or multiple solutions such as x=3, x=-7, each potential solution must be verified individually by substituting them back into the original equation to ensure they lead to an identity.
