Answer: 115 degrees

Step-by-step explanation:

Pretty vague question but with the info given im guessing that your looking for the last angle in the triangle which is 115 since all angles in a triangle must add up to 180

6x+9/x-5 x is not equal to 5 find inverse

algol [13]

You have f(x)=(<span>6x+9)/(x-5) and want to find the inverse function? Please note that the parentheses are obligatory here.

1. Replace "f(x)" with y: y = </span>(6x+9)/(x-5)
<span>
2. Interchange the variables x and y: x</span> = (6y+9)/(y-5)

3. Solve this result for y: x(y-5) = (6y+9), or xy-5x = 6y+9. Then:

xy-6y = 9 + 5x, or y(x-6) = 9+5x
9+5x
Then y = --------------
x-6

Here x may not = 6, because division by zero would occur otherwise.

Your medical research team is investigating the standard deviation of the cost of a 30-day-supply of a certain heart medication.

Valentin [98]

Considering the situation described, the hypothesis tested are given as follows:

The null hypothesis is $H_0: \sigma \geq 23$

The alternative hypothesis is $H_1: \sigma < 23$

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:

$H_0: \sigma \geq 23$

At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

$H_1: \sigma < 23$

Write an exponential function =for a graph that passes through (2,1) and (3,10). Ill give you whatever please help

GrogVix [38]

Answer:

$y = \frac{1}{100} \times 10{}^{x}$

Step-by-step explanation:

Use coordinates (2,1) and 3,10

The exponential equation is

$y = a \times b {}^{x}$

Plug in the x and y values.xfor both functions of coordinates.

$1 = a \times b {}^{2}$

$10 = a \times b {}^{3}$

Divide the equation with the larger exponet by the other equation.

$10 = b$

Substitute that in for one of the equations.

$10 = a \times 10 {}^{3}$

Solve for a.

$10 = a \times 1000$

$\frac{1}{100} = a$

So our exponetial equation is

$y = \frac{1}{100} \times 10 {}^{x}$
