The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The value of x is 6.2 units.
What is Tangent (Tanθ)?The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The value of x is,
x = AB - AC
x = 31(Tan 37°) - 31(Tan 29°)
x = 6.17659 ≈ 6.2 units.
Hence, the value of x is 6.2 units.

Answers
Answer and Step-by-step explanation:
f(n) = 45 - 4(n - 1)
This is the explicit formula for the sequence.
45 is the initial amount, which is why it is by itself.
The change in the sequence is take away 4, so this becomes a negative 4, which is then multiplied by (n - 1), where n is the term in the sequence.

Step-by-step explanation:Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
Solve this system using substitution: y=5x and 7x-3y=32
Answers
Answer:
x = -4 and y = -20
Step-by-step explanation:
y = 5x and 7x - 3y = 32
→ Substitute y = 5x into 7x - 3y = 32
7x - 15x = 32
→ Simplify
-8x = 32
→ Solve
x = -4
→ Substitute x = -4 into y = 5x

A technology company claims that 13% of customers who call the help desk cannot log in because they have their keyboard on caps lock, which blocks the log in process due to password case sensitivity. Brian, a help desk worker at this company, thinks this proportion is higher. The 95% confidence interval for the true proportion of customers who cannot log in due to caps lock is (0.128, 0.185). Is it reasonable to believe the true proportion of customers who cannot log in due to caps lock is greater than 13%?
Yes, because most of the values in the interval are above 0.13.
Yes, because the center of the interval is 0.1565, which is greater than 0.13.
No, because 0.13 is in the interval.
No, because there are values in the interval that are less than 0.13.

Look at the work for the following function. What mistake did they make when using the quadratic formula to find the solutions? What are the real solutions to the function?
Answers
Answer:
see below
Step-by-step explanation:
whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number
so this step is wrong
[tex] \sqrt{ - 9 { }^{2} - 4(1)(20) } [/tex]
the -9 ² , you must include the brackets to include the -1 in front of the 9
so it should be
[tex] \sqrt{( - 9) {}^{2} - 4(1)(20) } [/tex]
so you will get = 1
and then you continue with other parts of the formula and you will get real solutions

what is the average rate of change of the function f(x) over the interval [1,3] rounded to the nearest whole number f(x)=6(2.5)
Answers
Answer:
[f(1) - f(3)] / [1–3]
Step-by-step explanation:
Formula
f(x) = 6(2.5)
How to find
The average rate of change over the interval [a,b], or the secant line between the points a and b on the function f(x), is [f(a) - f(b)]/[a-b]. So, substitute a for 1 and b for 3, and you get [f(1) - f(3)] / [1–3]. The quotient of that is your average rate of change.
