Solve: logx64 = 3 which is an equivalent equation?

zepelin [54]

By applying the definition of logarithm, you have

$\log_x(64) = 3 \iff x^3 = 64$

So, if you consider the cubic root of both sides, you have

$x = \sqrt[3]{64} = 4$

WILL GIVE BRANLIEST HELP PLEASE!

allochka39001 [22]

I believe since you are looking for the angle of M<ABC, you just add both 120 and 25 together, since they practically share a point.

So 120 + 25 = 145

So I guess 145 would be your answer.

I remembered this type of problem from Geometry.

The scores on an exam are listed. If a teacher wants to explain how poorly the class did on the test, would she use the mean, me

Natasha_Volkova [10]

Mean because the mean is an average. That gives an overall understanding of what the entire class did.

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Brrunno [24]

Answer:

Converges at -1

Step-by-step explanation:

The integral converges if the limit exists, if the limit does not exist or if the limit is infinity it diverges.

We will make use of integral by parts to determine:

let:

$u=x$ $dv=e^(2x)\cdot{dx}$

$du=dx$ $v=2\cdot{e^(2x)}$

$\int\limits^a_b {u} \, dv = uv -\int\limits^a_b {v} \, du$

$\int\limits^a_b {x\cdot{e^2^x} \, dx =2xe^2^x- \int\limits^a_b {2e^2^x} \, dx$

$\int\limits^a_b {xe^2^x} \, dx = 2xe^2^x-2e^2^x-C$

We can therefore determine that if x tends to 0 the limit is -1

$\lim_{x \to \0} 2xe^2^x-2e^2^x=0-1=-1$
