We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B. Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7. We can get B on its own by making the equation this: $B = tan^{-1} (10/7)$

Now, we plug this into our calculator to get:

B = 55°, so angle B is 55°.

The masses of four planets in a solar system outside the Milky Way are given below.

zhenek [66]

Your answer is Planet B, Planet D, Planet A, Planet C.
Look at the exponents.
23 comes before 24 and 27. So 3.30 x 10 ^ 23 comes first. Next, 24, and there are 2, so go by the decimals, 4.87 comes before 5.97. So 4.87 x 10^24 comes before 5.97 x 10^24. Then, that leaves 1.89 x 10^27.

Assignment: Using Prime Factorization Investigation

damaskus [11]

Answer:

3(2 +7)
9(3 +5)
16(2 +3)
15(2 +5)
8(11 +3)

Step-by-step explanation:

6 + 21 = 2·3 + 3·7 = 3(2 +7)
27 + 45 = 3^3 + 3^2·5 = 9(3 +5)
32 + 48 = 2^5 + 2^4·3 = 16(2 +3)
30 + 75 = 2·3·5 + 3·5^2 = 15(2 +5)
88 + 24 = 2^3·11 +2^3·3 = 8(11 +3)

In each case, the factor outside parentheses is the greatest common factor, the product of the prime factors common to both numbers. When the same factor has different powers, the least power is the common factor.

Calculate the median 5,10,12,4,6,11,13,5

damaskus [11]

For this case, we have by definition that, the median of a set of numbers is the average number in the set, after the numbers have been ordered from lowest to highest. If there is an even number in the set, the median is the average of the two middle numbers.

So, the given set is:

{4,5,5,6,10,11,12,13}

Since there are 8 numbers, the set is even. Then we find the average of the two numbers in the middle:

$\frac {6 + 10} {2} = \frac {16} {2} = 8$

The median is 8

Whats an inverse function

vichka [17]

Answer:

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
