Answer:

Obtuse, scalene.

Step-by-step explanation:

In ΔSVU, one angle is 120° which is obtuse angle.

So, ΔSVU is a obtuse triangle.

All the sides have different measurements. So, It is a Scalene triangle.

Rewrite the following expression in logarithmic form and use that to solve for the variable. Show all work done in this process.

Llana [10]

Answer:

$ln(e^x)=ln(3)$

$x=1.099$

Step-by-step explanation:

You have the following exponential expression:

$2e^x=6$

You need to divide both sides of the equation by 2:

$\frac{2e^x}{2}=\frac{6}{2}\\\\e^x=3$

Now apply the function Natural logarithm to both sides of the function:

$ln(e^x)=ln(3)$

Note that now the exponential function is transformed into a logarithmic function.

By definition:

$ln(e^x)=x$ Because the base of the Natural logarithm is the Euler's number "e".

Then you can solve for "x":

$x=ln(3)\\x=1.099$ )

1) A chemist mixes an 8% nitric acid solution with a 5% nitric acid solution. How many milliliters of the 5% solution should the

Novay_Z [31]

Suppose the chemist uses x mL of the 8% acid solution, and y mL of the 5% solution.

The chemist wants to end up with a 500 mL solution, so

x + y = 500

and wants this solution to have a concentration of 6.8% acid. This means 6.8% of this volume should be acid. By volume, the 8% solution contributes 0.08x mL of acid, and the 5% solution contributes 0.05y mL, so

0.08x + 0.05y = 0.068(x + y) = 0.068 * 500 = 34

Now,

y = 500 - x

0.08x + 0.05(500 - x) = 34

0.08x + 25 - 0.05x = 34

0.03x = 9

x = 300

The chemist must use 300 mL of the 5% solution.
