Mathematics
1 answer:
Mekhanik [1.2K]3 years ago
3 0

Answer:

2.33

Step-by-step explanation:

The first step is to realize that angle A is 90-25= 65 degrees. From this, you can set up a law of sines equation.

\frac{\sin(65^\circ)}{5}=\frac{\sin(25^\circ)}{x}\\x=\frac{\sin(25^\circ)\cdot 5}{\sin(65^\circ)}\approx 2.33

Hope this helps!

A circle has an area of 30 in^2. What is the area of a 60 sector of this circle?
yuradex [85]

We use the ratio x:360 to find portions of the circle (again, through the ratio)

so we use 60/360 = x/30 in^2

1/6 = x/ 30

x = 5.

The answer is 5 in^2

Exercise 4.x2 Make a reasonable conjecture about the nth term in the sequence. 1 3 16 125 1296...
Ulleksa [173]

Answer:

The nth term in the sequence is given by the equation:

n_{th} =(n+1)^{n-1}

Step-by-step explanation:

Arranging a table for n and nth:

\left[\begin{array}{ccc}n&nth\\1&1\\2&3\\2&16\\4&125\\5&1296\end{array}\right]

It is easier to notice that 16 and 125 result from the second power of 4 and the third of 5, respectively, which are one number below their respective position. That is why we can deduce that the base of the power is n+1.

For n=2, the base n+1 results in 3, which matches the nth term for n=2. Since 3 is the result of 3 to the power of 1, 16 is 4 to the power of 2, and 125 is 5 to the power of 3, all the powers are one number behind n, so the power is given by n-1, giving the equation:

n_{th} =(n+1)^{n-1}

What is 70x + 56y = 56,000 into Slope-Intercept Form?
MAVERICK [17]

Answer:

i belive that the awnser is y=-1.25x+1000

Step-by-step explanation: you want to get y by itself so you would subtract x from both sides leaving you with

56y=-70x+56,000

then you would devide both sides by 56 leaving you with

y=-1.25x+1000
