log(x) - log(6) = 2 log(4)
Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):
log(x / 6) = 2 log(4)
Rewrite the right side, using the property n log(a) = log(aⁿ ):
log(x / 6) = log(4²)
log(x / 6) = log(16)
Cancel the logarithms (i.e. take the exponential of both sides):
exp(log(x / 6)) = exp(log(16))
x / 6 = 16
Solve for x :
x = 6 × 16
x = 96
For positive acute angles A and B it is known that sinA= 35/37 and tanB= 7/24. find the value of (A-B)
Answer:
54.8° to the nearest tenth of a degree
Step-by-step explanation:
m∠A = arcsin 35/37 = 71.075...
m∠B = arctan 7/24 = 16.2602...
m∠A - m∠B = 71.075 - 16.260 = 54.8° to the nearest tenth of a degree

How do electromagnets differ from regular magnets?
Answer:
Permanent Magnets and Electromagnets: What are the Differences? A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. ... An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.
Step-by-step explanation:
Electromagnets differ from regular magnets in that they require an electric current to generate a magnetic field.
Regular magnets, also known as permanent magnets, possess an inherent magnetic field due to the alignment of their atomic or molecular structure. They do not require an external power source.
On the other hand, electromagnets are made by wrapping a coil of wire around a magnetic core and passing an electric current through the wire. The electric current creates a magnetic field, and the strength of the magnetic field can be controlled by varying the current.
One key advantage of electromagnets is their ability to be turned on and off by controlling the electric current. This feature allows for a wide range of applications, such as in electric motors, generators, speakers, magnetic levitation systems, and more, where the magnetic field needs to be controlled or modulated. In contrast, regular magnets have a constant magnetic field that cannot be easily manipulated.

Seventeen thousand in standard form
Answer:
i dont know the answer may be search on chrome
Answer:
17 x 10³
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily. 10³ = 1000, so 4 × 10³ = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.
Unit 8: right triangles and trigonometry
Homework 2: special right triangles
HELP PLEASE!!
Answer:
x=50
y=25
Step-by-step explanation:
So for this triangle we can use trig. To find side x (the hypotenuse) we can do sin60 degrees. *remember SOHCAHTOA, so sin is opposite over hypotenuse.
sin60degrees=(25 * sqrt of 3)/x
multiply each side by x to get xsin60degrees=25*sqrt of 3. Then divide both sides by sin60degrees. Plug that in a calculator and you should get 50.
For side y, well you can use the characteristics of 30-60-90 triangles and by doing this we know that the short leg of this type of triangle is HALF of the hypotenuse and half of 50 is 25. If you didn't know this you could still use the cos of 60 degrees and get 25 as well.

-15 + -3 = -18
Rob owes his father $18.
Step-by-step explanation:
Rob has to pay back the same amount of money that he took. Since he took 15 dollars, he has to give back 15 dollars which makes the 15 negative. The same goes for the 3 in the equation.
To find out the total amount Rob has to pay back, we have to add -15 and -3, which is -18.

Answer: 6:5 ; 18:15 ; 36:30
Step-by-step explanation:
6/5 = x/15
5x = 6(15) use cross multiply
5x = 90
x = 18
6/5 = 36/x
6x = 5(36) use cross multiply
6x = 180
x = 30
Answer:
Answer below
Step-by-step explanation:
For every 6 taxis, there are 5 busses
if there are 15 busses, thats 3 sets of 5
6x3 is 18. so for every 15 busses, there are 18 taxis
If there are 36 taxis, thats 6 sets of 6
since there are 5 busses for every 5 taxis
5x6 is 40
for every 30 busses, there are 36 taxis
9. DOG WALKING Evan, a dog walker, charges $3 every block that he walks a dog. He also charges a $5 pick up fee when he comes to get a dog. How many blocks will he need to walk a dog in order to earn $26? Write an equation and solve the equation.
Answer:
Evan will have to walk 7 blocks
Step-by-step explanation:
Evan will have to walk 7 blocks because he gets $5 from picking up the dog, so subtract 5 from 26 to get 21. Next, you want to divide 21 by 3 to get 7 because $3 a block and you need to find how many blocks he needs to do.
Trig function - find the exact value
Answer:
3/5
Step-by-step explanation:
We can find ∅ by using the tangent function since we have the opposite and adjacent sides of ∅.
tan(∅)=1/2
tan^-1(tan(∅))=tan^-1(1/2)
∅=26.57
Since we are looking for cos(2∅), then we have cos(2(26.57))=cos(53.14)≈0.6
So the exact value is 3/5

Answer:
The fourth choice, Pink, is the correct answer.
Step-by-step explanation:
The first two options intersect, therefore the intersection is the solution. The third set of lines may seem like one line, however since we are dealing with two linear equations, it can be presumed that those are two lines on top of one another, therefore it has infinite solutions. The last option remaining is Pink, in which the lines are parallel and therefore will never intersect, making them have no solution.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
