Using perfect squares simplification, it is found that the value of the desired limit is of -4.

It is the value of a function as x approach

In this problem, the limit we want to find is given by:

[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2}[/tex]

If we just replace x by -2, we end with an undetermined limit, as we have 0/0.

However, the perfect square simplification states that:

a² - b² = (a - b)(a + b).

Hence:

x² - 4 = (x + 2)(x - 2).

Then:

[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2} = \lim_{x \rightarrow -2} \frac{(x + 2)(x - 2)}{x + 2} = \lim_{x \rightarrow -2} x - 2 = -2 - 2 = -4[/tex]

Hence, the value of the desired limit is of -4.

Step-by-step explanation:

the volume of a cylinder is

base area × height.

and the base is a circle, and the area of a circle is

pi×r²

remember, the radius is half the diameter.

so, in our case, the volume is

pi×(18/2)²×20 = pi×9²×20 = pi×81×20 = pi×1620 =

= 5,089.380099... in³ ≈ 5,089 in³

Hi!

[tex]\cfrac{bh}{2}[/tex]

Where b = base and h = height.

In the given problem, the base and height of the triangle are 10 inches and 7 inches.

Now, we can use the formula above.

If we plug in the given values, we have:

[tex]\dfrac{10*7}{2}[/tex]

Multiply 10 and 7:

[tex]\dfrac{70}{2}[/tex]

Divide:

[tex]35[/tex]

Using the triangle area formula, we have gotten a value of 35.

Therefore, the area of the triangle is 35 inches squared.

Answer:

35 inches²

Step-by-step explanation:

Given Base and Height of triangle: 10 inches and 7 inches

To determine the area of a triangle, multiply the base and the height. Then divide the product of the base and the height by 2.

Therefore, the "area of triangle" formula is:

[tex]\boxed{\text{Area of a triangle} = \frac{\text{Base} \times \text{Height}}2}[/tex]

Now, substitute the base and the height in the formula. Then, simplify the expression to determine the area of the triangle provided.

[tex]\implies \text{Area of the triangle} = \dfrac{\text{10} \times \text{7}}2}[/tex]

[tex]\implies \text{Area of the triangle} = \dfrac{70}2} = \boxed{35 \ \text{in}^{2}}[/tex]

Therefore, the area of the triangle is 35 inches².

Answer:109

Step-by-step explanation:

71 degree and x make a linear pair

71 + x = 180

x= 180- 71

x= 109

Answer:

the answer is, area of the square - a half of area of the circle

C=circle and S =square

radius of C is 10

so Area Of C is =

[tex]\pi r^{2} = \pi{10}^{2} = 100\pi[/tex]

area of S = 10×10 = 100

so the answer is

[tex]s - \frac{c}{2} = 100 - \frac{100\pi}{2} = 100 - 50\pi[/tex]

Answer:

405π

Step-by-step explanation:

Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height

The volume and the radius are given. (V=45π, r=3)

1. Solve for height

V=πr²h

45π=π3²h

45π/π=3²h

45=3²h

45=9h

45/9=h

h=5

2. Plug the new radius (3*3=9) into this formula and solve for "V"

V=π9²5

V=π81*5

V=405π

NEW VOLUME AFTER A TRIPLED RADIUS IS 405π

Step-by-step explanation:

using the Cosine rule in the triangle

cos x = [tex]\frac{8^2+15^2-11^2}{2(8)(15)}[/tex] = [tex]\frac{64+225-121}{240}[/tex] = [tex]\frac{168}{240}[/tex] , then

Answer:

AC ≈ 12

Step-by-step explanation:

the angle between the tangent AC and the radius BC is 90°

then Δ ABC is right

note that BC = 9 ( radius of circle )

using Pythagoras' identity in the right triangle

AC² + BC² = AB²

AC² + 9² = (9 + 6)² = 15²

AC² + 81 = 225 ( subtract 81 from both sides )

AC² = 144 ( take square root of both sides )

AC = [tex]\sqrt{144}[/tex] = 12

Answer:

30/45 or 2/3

Step-by-step explanation:

If you factor out a 10 from the numerator and a 9 from the denominator, you should get the following:

Numerator = 10 (a + b)

Denominator = 9 (x - y)

Since we know that (a + b) = 3 and (x - y) = 5, we can rewrite it as:

Numerator = 10(3)

Denominator = 9(5)

Therefore, the answer is 30/45, or 2/3.

The bones at the time they were​ discovered when the radioactive element​ carbon-14 has a​ half-life of total 5750 years are 10062.5-year-old.

Half lives is the time interval which is need to decay the atomic nuclei of a radioactive sample.

There is a scientist who determined that the bones from a mastodon had lost 70.3​% of their​ carbon-14.  Thus, the fraction remaining is,

f=1-(70.3/100)=1-0.703

f=1-(70.3/100)=0.297

Now the fraction remaining can be given as,

f=(1/2)ⁿ

Here, n is the half life elapsed. Put the value of fraction remaining.

0.297=(1/2)ⁿ

n=1.75

The radioactive element​ carbon-14 has a​ half-life of total 5750 years. Thus,

Years=1.75*5750

Years=10062.5

Thus, the bones at the time they were​ discovered when the radioactive element​ carbon-14 has a​ half-life of total 5750 years are 10062.5-year-old.

The coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

-4π/5

To find the coterminal angle, add and subtract by 2π in the angle -4π/5

Coterminal angle:

= -4π/5 - 2π

= -14π/5

= -4π/5 + 2π

= 6π/5

Reference angle:

= π - 4π/5  (as the angle lies in the second quadrant)

= π/5

Thus, the coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.
