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 ;

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

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 ;

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]

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

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]

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.

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

Answer:

400x45.2=18080

Step-by-step explanation:

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

Answer:

w = 63

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 interior angles.

w + 28 is an exterior angle of the triangle , then

w - 2 + w - 33 = w + 28 , that is

2w - 35 = w + 28 ( subtract w from both sides )

w - 35 = 28 ( add 35 to both sides )

w = 63

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.

D

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{13}{x}[/tex] ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = [tex]\frac{13}{cos66}[/tex] ≈ 32.0 ( to the nearest tenth )
