Explanation:
Given a point
(
a

Evaluate the limit of (tanx)^2/(1-cosx) as x tends to 0
Please show your work. Thanks!
Rewrite the limand as
[tex]\dfrac{\tan^2(x)}{1 - \cos(x)} = \dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))}[/tex]
Multiply the numerator and denominator by 1 + cos(x). Then
[tex]\dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))} \cdot \dfrac{1+\cos(x)}{1+\cos(x)} = \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)(1 - \cos^2(x))} \\\\= \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)\sin^2(x)} \\\\ = \dfrac{1 + \cos(x)}{\cos^2(x)}[/tex]
As x goes to 0, the limand goes to (1 + 1)/1² = 2.
We are given with a limit :-
[tex]{\quad \blacktriangleright \blacktriangleright \blacktriangleright {\displaystyle \sf \lim_{x\to 0}\dfrac{\tan^{2}(x)}{1-\cos (x)}}}[/tex]
We know that ;
[tex]{\boxed{\bf \dfrac{\sin (\theta)}{\cos (\theta)}=\tan (\theta)}}[/tex]Using this , the above limit can be written as ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)}{\cos^{2}(x)\{1-\cos (x)\}}}[/tex]
Multiplying and dividing both numerator and denominator by [tex]{\sf 1+\cos (x)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos (x)\}\{1+\cos (x)\}}}[/tex]
We knows a identity that is
[tex]{\boxed{\bf a^{2}-b^{2}=(a+b)(a-b)}}[/tex]Using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos^{2}(x)\}}}[/tex]
We knows another Trigonometric identity i.e ;
[tex]{\boxed{\bf 1-\cos^{2}(\theta)=\sin^{2}(\theta)}}[/tex]Now , using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\cancel{\sin^{2}(x)}\{1+\cos (x)\}}{\cos^{2}(x)\cancel{\sin^{2}(x)}}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{1+\cos (x)}{\cos^{2}(x)}}[/tex]
Putting the limit we have ;
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+\cos (0)}{\cos^{2}(0)}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+1}{1^{2}} \quad \qquad \{\because \cos (0)=1\}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{2}{1}}[/tex]
[tex]{:\implies \quad {\displaystyle \therefore \quad \bf \underline{\underline{\lim_{x\to 0}\dfrac{\tan^{2}(x)}{1-\cos (x)}=2}}}}[/tex]

Which of the following is an equation of the line through (2, 3) and (−1, −12
Answer:
y = 5x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 3 ) and (x₂, y₂ ) = (- 1, - 12 )
m = [tex]\frac{-12-3}{-1-2}[/tex] = [tex]\frac{-15}{-3}[/tex] = 5 , then
y = 5x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 3 )
3 = 10 + c ⇒ c = 3 - 10 = - 7
y = 5x - 7 ← equation of line

A 14.5-gallon gasoline tank is $\frac{3}{4}$
full. How many gallons will it take to fill the tank? Write your answer as a mixed number.
The number of gallons it take to fill the tank is 3.625 gallon.
Given that, a 14.5-gallon gasoline tank is 3/4 full.
Let the number of gallons it take to fill the tank is x.
Now, the number of gallons of gasoline tank = 14.5×3/4
= 14.5×0.75
= 10.875
Here, 10.875+x=14.5
x=14.5-10.875
x=3.625
Therefore, the number of gallons it take to fill the tank is 3.625 gallon.

PLZ help is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer.
Answer:
Yes
Step-by-step explanation:
These triangles are congruent by one of two theorems. The first one would be HL, or hypotenuse leg, or side, angle,side. the congruence statement would be
Angle Y is congruent to angle B
Side YZ is equal to BC
Side YX is equal to Side BA
So, triangle XYZ is congruent to triangle ABC by either the HL, OR THE SAS theorem.
Billy dove off a cliff into the water. The cliff was 15 ft. above sea level. After diving into the water, he swam 5 ft. below the opposite elevation of the cliff and found a golden ring. At what elevation did he find the golden ring?
Answer:
Billy found the ring at -20 ft
Step-by-step explanation:
He started at 15 ft
He dove off the cliff, then swam 5 feet under the opposite of the cliff's elevation
The opposite of the cliff's elevation would be -15, and if he swam five feet under that, it would be -15 + -5 = -20
So, Billy found the ring at -20 ft

Find the perimeter of ABCD
Answer:
157
Step-by-step explanation:
We can see that both of the figures are congruent! Judging from their angles. Since they are congruent, they have equal sides. We can assume that both have the same sides of each other. So all we have to do is add up all the sides.

BRAINLIEST 3/5(x−710)=−314
Answer: x = 560/3
Step-by-step explanation:
First! We are going to be using the PEMDAS method! If you have any questions about this method please go ahead and ask below! The first step in our equation is the P - parenthesis, so we are going to multiply [tex]\frac{3}{5}[/tex] to everything inside of the parenthesis (x and -710)!
[tex]\frac{3}{5} (x -710) = -314[/tex]
[tex]\frac{3}{5}x+(\frac{3}{5}*-710)=-314[/tex]
[tex]\frac{3}{5}x -426 = -314[/tex]
Now, we are going to add 426 to both sides of the equation, to single out the "x" variable!
[tex]\frac{3}{5}x= 112[/tex]
Finally, let's multiply both sides by [tex]\frac{5}{3}[/tex] to cancel out the [tex]\frac{3}{5}[/tex] fractions, to get the "x" variable alone.
[tex]x=\frac{560}{3}[/tex]

(x-1)(x+7)=(x+1)(x-3)
Answer:
x = 1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form: x= 1/2
Decimal form: x = 0.5
Answer:
x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−1)(x+7)=(x+1)(x−3)
Step 1: Simplify both sides of the equation.
x2+6x−7=x2−2x−3
Step 2: Subtract x^2 from both sides.
x2+6x−7−x2=x2−2x−3−x2
6x−7=−2x−3
Step 3: Add 2x to both sides.
6x−7+2x=−2x−3+2x
8x−7=−3
Step 4: Add 7 to both sides.
8x−7+7=−3+7
8x=4
Step 5: Divide both sides by 8.
8x/8 = 4/8
x = 1/2
