54. log(20x) - log4 = 2​

Mathematics
1 answer:
Luba_88 [7]3 years ago
4 0

Answer:

x=e^2/5

Step-by-step explanation:

log(20 x) - log(4) = 2

Add log(4) to both sides:

log(20 x) = 2 + log(4)

Cancel logarithms by taking exp of both sides:

20 x = 4 e^2

Divide both sides by 20:

And we get Answer:

x = e^2/5

Janet is designing a frame for a client. She wants to prove to her client that m∠AGE ≅ m∠CHE in her sketch. What is the missing
Amiraneli [1.4K]

Answer:

I believe the answer is transative property. I'm currently taking the test so I'm not 100% sure if I'm right yet.

Step-by-step explanation:

In step one, AGE and HGB are verticle angles since they are opposite of each other. then step two is alternate interior angles because they are interior angles opposite of each other, self-explanatory. the reason I choose the transitive property over the corresponding angles theorem is because the transitive property states: among A B and C, if A=B and B=c then A=C and in this case since AGE=HGB andHGB=CHE then AGE=CHE. I hope this helps and if you know the right answer just put it in the comments, if I'm wrong ofc.

Is the square root of 225 a rational number?
MArishka [77]

Step-by-step explanation:

\text{The principal square root}:\\\\\sqrt{a}=b\iff a^2=b\ \text{for}\ a\geq0\ \text{and}\ b\geq0.\\\\\text{The square root:}\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\\===================

\text{If you want the principal square root (arithmetic square root):}\\\\\sqrt{225}=15\ \text{because}\ 15^2=225\\\\\text{If you want square root (algebraic square root):}\\\\\sqrt{225}=\pm15\ \text{because}\ (-15)^2=225\ \text{and}\ 15^2=225

let us assume that the first company the cab flat rate is 5$ and the cap driver charges 2$ per mile .for the second company the cab flat rate is 3$ and the cab driver charges 3$ per mile.

a. the company charges per ride at least 5$ and an extra 2$ per mile

b.the equation we will choose is slope intercept since we know the

y-intercept which is the cab flat rate .

y=mx+b

where

m :is the slope

b:is the y-intercept

y:total amount

x. is the milage

total amount=2x+5.

c.the slope will be 2$ which is the change in amount per mile.the y-intercept will be the cab's flat rate.
