Step-by-step explanation:
ln(x² - 25) = 0
x² - 25 ≤ 0
x² ≤ 25
x ≥ -5 or x ≤ 5
-5 ≤ x ≤ 5
ln(x² - 25) = 0 , -5≤x≤5
x² - 25 = 1
x² = 26
x = -√26 and √26 are the solution of the equation

why does the formula for area of a circle make sense
Answer:
Step-by-step explanation:
The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 18 miles per hour slower than the eastbound train. If the two trains are 300 miles apart after 2 hours, what is the rate of the westbound train? Do not do any rounding.
Answer:
66 mph
Step-by-step explanation:
w = e - 18
2w + 2e = 300
2 (e - 18) + 2e = 300
2e - 36 + 2e = 300
4e - 36 = 300
4e = 300 + 36 = 336
e = 84 mph
w = 66 mph
The westbound train is travelling at 66 mph
Given the operation a * b = 4a^2 - b, evaluate i) 2 * 8 ii) 2 * 8 * 2
Mathematical operations are used to represent the relationship between variables
The results of the operations are 8 and 254
The operation is given as:
a * b = 4a^2 - b
(a) 2 * 8
This means that:
a = 2
b = 8
So, we have:
2 * 8 = 4 * 2^2 - 8
Evaluate the exponents
2 * 8 = 4 * 4 - 8
Multiply
2 * 8 = 16 - 8
Subtract
2 * 8 = 8
(b) 2 * 8 * 2
In (a), we have:
2 * 8 = 8
So, the operation becomes
2 * 8 * 2 = 8 * 2
This means that:
a = 8
b = 2
So, we have:
8 * 2 = 4 * 8^2 - 2
Evaluate the exponents
8 * 2 = 4 * 64 - 2
Multiply
8 * 2 = 256 - 2
Subtract
8 * 2 = 254
Hence, the results of the operations are 8 and 254

A gallon is 128oz. An airplane can carry 1,445 gallons of fuel. Write the number of ounces of fuel the plane can carry.
Step-by-step explanation:
one gallon is 128oz.
1445 gallons are how many Oz?
that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"
or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"
it all works with multiplication. it is the ultimate application for multiplication.
that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.
and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.
128 × 1445 = 184,960oz

Answer:
A) 1, 4, 5, 9, 14, 23, 37
B) 2, 4, 6, 10, 16, 26, 42
Step-by-step explanation:
1. The Fibonacci sequence states that each number is the sum of the two numbers before it.
For example, if we have the first two numbers of a sequence as 5 then 6, the next term would be 11.2. Given the information above, let's solve the question.
-> A: 9 + 14 = 23, 14 + 23 = 37
The next two terms for sequence A are 23 then 37-> B: 10 + 16 = 26, 16 + 26 = 42
The next two terms for sequence B are 26 then 42Therefore, the answer is:
A) 1, 4, 5, 9, 14, 23, 37
B) 2, 4, 6, 10, 16, 26, 42

x/2-1=3 what is X PLEASE HELPPPPPPPPPPP
x / 2 - 1 = 3
Add 1 to both sides.
x / 2 = 4
Multiply both sides by 2.
x = 8
Now lets put in 8 for x in our original equation:
8 / 2 - 1 = 3
4 - 1 = 3
3 = 3
This is correct, therefore we know x = 8.

What is the value of 6a - 2b when a = 5 and b = 8
Answer:
14
because 6(5)=30 and -2(8)=-16
30-16=14
Answer:
14
Step-by-step explanation:
All we need to do to get the value of 6a-2b is to plug in 5 for the variable "a" (replace a with 5) and plug in 8 for variable "b" (replace b with 8).
Because the variables are right next to the number, that indicates multplication, so the equation is basically saying 6*a-2*b
So let's plug in the numbers for the variables and solve:
6*5-2*8
6*5=30
2*8=16
30-16=14
So our final answer is 14
How many ways are there to travel in xyzw space from the origin (0, 0, 0, 0) to the point (4, 3, 5, 4) by taking steps one unit in the positive x, positive y, positive z, or positive w direction
There are 24 ways how a particle can travel in XYZW space from the origin to the point (4, 3, 5, 4).
The number of ways how a particle can travel in XYZW space from the origin is equal to the total permutations associated to the quantity of coordinates within the generated space. That is to say:

If Lisa paid $175.98 for 2 pair of shoes and 3 pair of jeans. Each pair of shoes cost 24.99. If each pair of jeans cost the same amount, then each pair of jeans cost is $42.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Lisa paid $175.98 for 2 pair of shoes and 3 pair of jeans
Each pair of shoes cost 24.99.
Each pair of jeans cost the same amount, we need to find how much did each pair of jeans cost.
As their are two pair of jeans
24.99+24.99=49.988
49.988 is the cost of pair of shoes.
Now let us remove 49.988 from $175.98 to find cost of jeans
175.988-49.988
125.992
$125.992 is the cost of three jeans
Now divide this by three to get cost of each jeans
125.992 which means 126, divide 126 by 3.
126/3=42
Hence, Each pair of jeans cost is $42

Tina spends $50.86 at the craft store. She buys 5 yards of fabric at $8.98 per yard and 2 spools of thread. What is the price of one spool of thread?
Answer:
One spool of thread is $2.98
Step-by-step explanation:
Answer:
$ 2.98
Step-by-step explanation:
Total amount spent by Mila equals $50.86
She bought 5 yards of fabric at $8.98 per yard. Hence, the total amount she spent on fabric is 8.98 × 5 = $44.9
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $50.86
Amount spent on thread = $50.86 - Amount spent on fabrics.
Amount spent on thread = $50.86 - $44.9 = $5.96
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $5.96, one spool would cost $5.96 ÷ 2 = $2.98
One angle of a right triangle measures 60°. What is the measure of the other acute angle?
Answer:
30°
Step-by-step explanation:

An angle measures 75.8° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
<1 = 82.9 degrees
<2 = 7.1 degrees
Step-by-step explanation:
<1 = x
<2 = x - 75.8
x + x - 75.8 = 90 degrees
2x = 90 + 75.8
x = 165.8/2
x = 82.9
