Answer:
x = ±√2
Step-by-step explanation:
x - 1 = 1/(x + 1)
(x -1)(x + 1) = 1 Multiplied each side by x + 1
x² - 1 = 1 Difference of two squares
x² = 2 Add 1 to each side
x = ±√2
x-1 is the reciprocal of x+1 when x = -√2 or x = √2.
Check:
(a) x = -√2
-√2 - 1 = 1/(-√2 + 1)
-(√2 + 1) = (√2 +1)/[(-√2 +1)(√2 + 1)]
-(√2 + 1) = (√2 +1)/(-2 +1)
-(√2 + 1) = (√2 +1)/(-1)
-(√2 + 1) = -(√2 +1)
(b) x = √2
√2 - 1 = 1/(√2 + 1
√2 - 1 = (√2 - 1)/[(√2 + 1)(√2 - 1) ]
√2 - 1 = (√2 - 1)/(2 - 1)
√2 - 1 = (√2 - 1)/1
√2 - 1 = √2 - 1
OK.
Answer:x = ±√2
Step-by-step explanation: this is because reciprocal means the numerator and denominator switches
So the equation is x-1=1/(x+1)
And you solve for it thats how u get the answer

What is accurate about the scientific results learned by counting tree rings? Study of tree rings and associated geology shows that the Earth is 12,000 years old, but no older. Study of tree rings and associated geology shows that the Earth is exactly 12,429 years old. Study of tree rings by themselves shows that the Earth is 4.6 billion years old. Study of tree rings and associated geology shows that the Earth is more than 12,429 years old. Study of tree rings and associated geology proves that the Earth is 5,000 years old, but no older.
Answer:
The correct answer is "Study of tree rings and associated geology shows that the Earth is more than 12,429 years old"
Step-by-step explanation:
While tress have been growing long enough to prove the earth is more than 12,000 years old, it is not able to prove much longer than that. Luckily geology is able to show is that Earth is over 4.6 billions years old. As a result, the above is the only true statement.
The age of the Earth is approximately 4.5 billion years, as determined by radioactive dating methods and supported by other geological evidence. Although not directly determining the Earth's age, the study of tree rings provides valuable information about climate conditions in specific periods.
Explanation:The scientific study of tree rings, known as dendrochronology, can provide valuable information about the Earth's climate in different periods. However, it doesn't directly determine the overall age of the Earth.
Conversely, radioactive dating methods, like uranium-238 dating or rubidium-strontium dating, have been used to determine the Earth's age by dating the oldest rocks and minerals on Earth's crust. For example, the Jack Hills zircons from Australia were found by uranium-lead dating to be nearly 4.4 billion years old.
Using these dating methods in connection with the study of tree rings and other geological evidence, scientists have estimated that the age of the Earth is approximately 4.5 billion years.
This age is significantly older than what could be derived from tree rings alone, as the oldest living trees, like the Methuselah tree, are estimated to be just over 4,800 years old.

Julio is lifting weights. He wants to have 210 pounds on the bar. How many 15-pound weights should he put on the bar?
Answer: 14 15-pound weights
Step-by-step explanation:
15 × 14= 210
Julio should put 14 fifteen-pound weights on the bar to achieve a total weight of 210 pounds.
Julio wants to have a total of 210 pounds on the barbell. Since each weight he will add is 15 pounds, we simply need to divide the total desired weight by the weight of one plate to determine the number of plates required.
Here is the calculation:
Divide 210 pounds by 15 pounds per weight.210 \/ 15 = 14.Therefore, Julio should put 14 fifteen-pound weights on the bar to reach a total of 210 pounds.
At this rate, would a person your age (18 years old) have contributed a ton of garbage? On average, how long does it take for each person to throw away a ton, or 2000 pounds of garbage?
Answer: Yes. On average, it takes about 455 days for 1 person to throw away 1 ton of garbage, so just over 1 year.
Step-by-step explanation: The average person throws away 4.4 pounds of trash daily. So, the way to figure this out is 2,000 divided by 4.4 to find out the number of days it would take to throw away 2,000 pounds of trash.
According to the Rational Root Theorem, which of the following values is a possible rational root of the polynomial p(x)=x2+3x+12?
A. 24
B. -1/2
C. -2
D. 1/6
E. 1/2
Answer:
C. -2
Step-by-step explanation:
Since the leading coefficient is 1 and rational roots are of the form ...
±(divisor of the constant)/(divisor of the leading coefficient)
all of the possible rational roots must be whole number diviors of 12. The only one on the list is -2.
The Rational Root Theorem allows us to determine that -2 is a possible rational root for the polynomial p(x)=x2+3x+12.
Explanation:According to the Rational Root Theorem, the possible rational roots of a polynomial equation can be found by taking all the factors of the constant term (in this case, 12) and dividing them by all the factors of the leading coefficient (in this case, 1 as the coefficient for x2 is 1). The factors of 12 are ±1, ±2, ±3, ±4, ±6, ±12. As our leading coefficient is 1, our possible roots can include ±1, ±2, ±3, ±4, ±6, ±12.
Looking at the list of options provided: A. 24, B. -1/2, C. -2, D. 1/6, E. 1/2, we see that only -2 is a possible rational root for the polynomial p(x)=x2+3x+12 based on the Rational Root Theorem.

Determine the graph of the polar equation r =6/2-2cos theta
(picture provided)
Answer:
Choice D is correct
Step-by-step explanation:
The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;
[tex]r=\frac{3}{1-cos(theta)}[/tex]
The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.
The value of the directrix is determined as;
d = k/e = 3/1 = 3
The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;
x = -3
Thus, the polar equation represents a parabola that opens towards the right with a directrix located at x = -3. Choice D fits this criteria
Find the measure of the angle with the greatest measure (picture provided)
Answer:
The measure of the greatest angle is about 81° ⇒ answer (b)
Step-by-step explanation:
* Let the given triangle is ΔABC where,
- a = 18 inches ⇒ opposite to angle A
- b = 21 inches ⇒ opposite to angle B
- c = 14 inches ⇒ opposite to angle C
∵ The greatest angle is opposite to the largest side
∴ The greatest angle will be angle B because b is the largest side
* By using cos Rule:
∵ b² = a² + c² - 2ac cos(B)
* Lets re-arrange the terms to find the measure of angle B
∴ 2ac cos(B) = a² + c² - b²
∴ cos(B) = (a² + c² - b²)/2ac
∴ cos(B) = (18² + 14² - 21²)/2(18)(14) = 79/504
∴ m∠B = 80.98 ≅ 81°
∴ The measure of the greatest angle is about 81°

How many total circles will be used if there are 20 rows of circles? Show all calculations.
Answer:
210
Step-by-step explanation:
As there is one circle in first row, 2 circles in 2nd row and three in third row, which clearly implies that the number of circles in each row is equal to the row number. So, we have to calculate sum of first 20 numbers to calculate the total number of circles.
n=20
Total Circles=(n(n+1))/2
=(20 (20+1))/2
=(20(21))/2
= 420/2
=210
So the total number of circles will be 210.

Answer the following question in 1-2 complete sentences. How is the measure of <1 and the measure of <2 related to the exterior 123° angle?
Answer:
<1:88
<2:65
<3:115
Step-by-step explanation:
Since we know that a line and the inside of a triangle equals 180 than we can use that to identify the missing angles.Using what we know about a line we can subtract 92 from 180 and we get 88, knowing that angle 1(<1)is the only angle that rest on that line than we know that <1 is 88.(to check this you can add 92 plus 88 and you get 180)Then switching hands,we can now figure out the interior missing angle 2(<2).There are two ways you can do this,Add all the interior angles together and then subtract from 180(88+57=145 then 180-145=35)or you can subtract all the known interior angles and then the answer is your missing angle(180-57-88=35).Now switching again, in order to find <3 then you have to find which number falls on the angle which we are looking for.Which would be 35 or <2.Now all you have to do is subtract 180-35=145
Part B:
I agree with the other person below⬇⬇⬇
Answer:
Step-by-step explanation:
(A) From the given figure, we have
[tex]{\angle}1+92^{\circ}=180^{\circ}[/tex] (Linear pair)
⇒[tex]{\angle}1=180^{\circ}-92^{\circ}[/tex]
⇒[tex]{\angle}1=88^{\circ}[/tex]
Thus, the measure of [tex]{\angle}1[/tex] is [tex]88^{\circ}[/tex].
Also, using the angle sum property in the given triangle, we get
[tex]{\angle}1+{\angle}2+57^{\circ}=180^{\circ}[/tex]
⇒[tex]88^{\circ}+{\angle}2+57^{\circ}=180^{\circ}[/tex]
⇒[tex]{\angle}2+145^{\circ}=180^{\circ}[/tex]
⇒[tex]{\angle}2=35^{\circ}[/tex]
Thus, the measure of [tex]{\angle}2[/tex] is [tex]35^{\circ}[/tex].
And, [tex]{\angle}2+{\angle}3=180^{\circ}[/tex]
⇒[tex]35^{\circ}+{\angle}3=180^{\circ}[/tex]
⇒[tex]{\angle}3=145^{\circ}[/tex]
Thus, the measure of [tex]{\angle}3[/tex] is [tex]145^{\circ}[/tex].
(B) Exterior angle theorem states that the exterior angle is equal to the sum of the two interior angles, thus from the given figure, we have
[tex]{\angle}1+{\angle}2=123^{\circ}[/tex]
Therefore, the relationship between the measure of [tex]{\angle}1[/tex] and [tex]{\angle}2[/tex] to exterior angle is [tex]{\angle}1+{\angle}2=123^{\circ}[/tex].

Niu has decorated xxx cards. He started with 242424 stickers, and he used 444 stickers per card. Which expressions can we use to describe how many stickers Niu has left?
Answer:
The required expression is 24 - 4x
Step-by-step explanation:
Given,
Initial number of stickers she has = 24,
Also, the number of stickers she used for a card = 4,
⇒ the number of stickers she used for x cards = 4x,
So, the number of stickers she left after decorating x cards = Initial number of stickers - the number of stickers used for x cards,
= 24 - 4x
Which is the required expression.

Find the polar equation of the conic with the focus at the pole, directrix y = -6, and eccentricity 4 (picture provided)
Answer:
Choice B is correct
Step-by-step explanation:
The eccentricity of the conic section is given as 4 and thus the conic section is a hyperbola. Hyperbolas are the only conic sections with an eccentricity greater than 1.
Next, the directrix of this hyperbola is located at y = -6 implying that the hyperbola will be opening upwards. Consequently, the polar equation of this hyperbola will be of the form;
[tex]r=\frac{k}{1-4sin(theta)}[/tex]
The value of k in the numerator is the product of eccentricity and the absolute value of the directrix;
k= 4*6 = 24
The polar equation is thus given by alternative B

Answer:
Shifted horizontally to the right 3 units, and shifted vertically down 2 units
Step-by-step explanation:
The parent graph of this equation is y = |x|
There are 2 translations to this graph for the equation y = |x - 3| - 2
The "x - 3" part shifts the graph to the right 3 units
The -2 shifts the graph vertically down 2 units
See below for the parent graph, and the graph of the equation we are working with
The graph of function y = |x - 3| - 2 is shown in figure.
What is Translation?A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
The equation is,
⇒ y = |x - 3| - 2
Now,
Since, The equation is,
⇒ y = |x - 3| - 2
Clearly, The equation y = |x - 3| - 2 is the translation of y = |x| with 3 units right and 2 units up.
Thus, The graph of function y = |x - 3| - 2 is shown in figure with 3 units right and 2 units up translation of y = |x|.

We have by definition:
[tex]\frac {d} {dx} [x ^ n] = nx ^ {n-1}[/tex]
So:
[tex]\frac {df (x)} {dx} = - (- 1 * 11 * x ^ {- 1-1}) = 11x ^ {- 2} = \frac {11} {x ^ 2}[/tex]
We evaluate for [tex]x = 9[/tex] and we have:

[tex]\frac {d (s (t))} {dt} = 0- (1 * 10 * t ^ {1-1}) = - 10 * t ^ 0 = -10[/tex]
So, the instantaneous velocity is -10
Answer:
-10
A container is in the shape of a rectangular prism with a square base. It has a volume of 99 cubic inches and a height of 11 inches. How many softballs with a diameter of 3.8 inches will fit into the container? Use the drop-down menus to explain your answer.
Answer:
A total of zero softballs will fit into the container
Step-by-step explanation:
step 1
Find the dimensions of the base of the prism
we know that
The volume of the prism is equal to
[tex]V=Bh[/tex]
where
B is the area of the base
h is the height of the prism
In this problem we have
[tex]V=99\ in^{3}[/tex]
[tex]h=11\ in[/tex]
substitute in the formula and find the area of the base B
[tex]99=B(11)[/tex]
[tex]B=99/11=9\ in^{2}[/tex]
the length side of the square base is the square root of the area
so
[tex]\sqrt{9}=3\ in[/tex]
we have that
The diameter of the softball 3.8 inches will fit (11/3.8=2.89 ) 2 times in the length of the container
The diameter of the softball 3.8 inches will fit 0 times in the width of the container
so
A total of 0 times of softballs will fit in the width of the container
therefore
A total of zero softballs will fit into the container
Answer:
Zero softballs with a diameter of 3.8 inches will fit into the container as length of the container is less the diameter of the softball.
Zero softballs can fit in length and zero softballs will fit in width.
Step-by-step explanation:
Length of the square base in rectangular pyramid = s
Breadth of the square base in rectangular pyramid = s
Height of the square base in rectangular pyramid ,l = 11 inches
Volume of the square base in rectangular pyramid ,V=[tex]99 inches^3[/tex]
Volume of the cuboid = l × b × w
V= s × s × l
[tex]99 inches^3=s^2\times 11 inches[/tex]
s = 3 inches
Softballs with a diameter of 3.8 inches.
But the length of the container is less the diameter of the softball which means not even single ball will not be able to get into the container. So zero softballs can fit in length and zero softballs will fit in width.
"Which number can be inserted in the parentheses so the numbers are ordered from least to greatest?" -3,(),-1 1/8 A. -3 1/2 B. 0 C. -2 1/4 D 1 1/2
Answer:
Option C
Step-by-step explanation:
The first number is - 3, then we have a blank and the third number is - 1 1/8
In order for the numbers to be arranged from least to greatest, the number in the center should be greater than -3, and lesser than -1 1/8
Note that for negative numbers, the larger the constant, the smaller the number. i.e. -5 is smaller than -4.
So from the given options, the only number that is greater than -3 and lesser than -1 1/8 is - 2 1/4
So, option C gives us the correct answer to have the numbers ordered from least to greatest.
