Use the function y = 50 tan x on the interval 0 &lt; x &lt; 150 Complete the ordered pair (x, 125). Round your answer to the nea
Colt1911 [192]

The value of x to the nearest whole number is 68 degrees

<h3>Equations and expressions</h3>

Given the trigonometry function shown below:

y = 50 tan x

For the coordinate (x, 125)

If the value of y is 125, then;

125 = 50tanx

tanx = 125/50

tanx = 2.5

x = arctan(2.5)

x = 68.19

Hence the value of x to the nearest whole number is 68 degrees

Maggie’s brother is three years younger than twice her age. The sum of their ages is 24. How old is maggie?
JulsSmile [24]

To solve this problem, we must set up a system of equations. In this case, let's let Maggie's age be represented by the variable m and her brother's age be represented by the variable b. We are told that the sum of their ages is 24, which gives us our first equation: m + b = 24. We can construct our next equation from the first sentence of given information: b = 2m - 3. This makes our system of equations:

m + b = 24

b = 2m - 3

To solve, we are going to substitute the value for b in terms of m given by the second equation into the first equation for the variable b.

m + b = 24

m + 2m - 3 = 24

To simplify, we must first combine the variable terms on the left side of the equation using addition.

3m - 3 = 24

Next, we should add 3 to both sides of the equation to get the variable term alone on the left side of the equation.

3m = 27

Finally, we should divide both sides by 3 in order to get the variable m alone.

m = 9

Therefore, Maggie is 9 years old (using the first equation and substituting in this value you can find that her brother is 15 years old).

Hope this helps!
