Answer:

B) 4/5

Step-by-step explanation:

The cosine of one of the angles is the same as the sine of the other angle.

In this case, the cos(M) = 4/5, and the sin(K) is also 4/5.

Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,0

Sphinxa [80]

Answer:

$Sea\ Level = 0\ ft$

The farthest point is the Challenger Deep

Step-by-step explanation:

Given

$Highest = +29029ft$

$Least = -35,797ft$

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

$Sea\ Level = 0\ ft$

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

$Highest = +29029ft$ to $Least = -35,797ft$

-35,797 ft has the highest magnitude.

Hence:

<em>The farthest point is the Challenger Deep</em>

Find the third degree polynomial function that has an output of 40 when x=1, and has zeros −19 and −i?

Yanka [14]

Answer:

$f(x) = (x + 19)(x^2 + 1)$

Step-by-step explanation:

Complex numbers:

The following relation is important for complex numbers:

$i^2 = -1$

Zeros of a function:

Given a polynomial f(x), this polynomial has roots $x_{1}, x_{2}, x_{n}$ such that it can be written as: $a(x - x_{1})*(x - x_{2})*...*(x-x_n)$ , in which a is the leading coefficient.

Has zeros −19 and −i

If -i is a zero, its conjugate i is also a zero. So

$f(x) = a(x - (-19))(x - (-i))(x - i) = a(x+19)(x+i)(x-i) = a(x+19)(x^2 - i^2) = a(x + 19)(x^2 + 1)$

Output of 40 when x=1

This means that when $x = 1, f(x) = 40$ . We use this to find the leading coefficient a. So

$f(x) = a(x + 19)(x^2 + 1)$

$40 = a(20)(2)$

$40a = 40$

$a = 1$

The polynomial is:

$f(x) = (x + 19)(x^2 + 1)$

What is the slope and y intercept of the following linear equation:y=1/3×-2

gulaghasi [49]

Answer:

Step-by-step explanation:

The general formula for slope-intercept form is y = mx + b

We can see that m (slope) equals 1/3 here. We can also see that the y-intercept (b) is -2. Another way to find the y intercept is to make x equal to 0. You get 0 - 2 which equals -2

Note:

If youre ever asked for the x-intercept, make y equal to zero and solve for x.
