Answer:

Rectangle: bh or l · w

Circle: pi(r)²

Answer:

The value is m = 3.

Step-by-step explanation:

Multiplication of terms with same base and different exponents:

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.

In this question:

We have the following expression:

[tex](\frac{3}{8})^{2m} \times (\frac{3}{8})^6 \times (\frac{3}{8}) = (\frac{3}{8})^13[/tex]

Applying the property:

[tex](\frac{3}{8})^{2m+6+1} = (\frac{3}{8})^13[/tex]

[tex](\frac{3}{8})^{2m+7} = (\frac{3}{8})^13[/tex]

Since the bases are equal, we can equalize the exponents:

[tex]2m + 7 = 13[/tex]

[tex]2m = 6[/tex]

[tex]m = \frac{6}{2} = 3[/tex]

The value is m = 3.

Answer:

The answer is x^2( [tex]\sqrt[4]{x^2}[/tex] ).

Step-by-step explanation:

To find an expression equivalent to 4 sqrt x^10, start by simplifying 4 sqrt x^10. To simplify the original equation, rewrite [tex]x^{10}[/tex] as ([tex]x^{2}[/tex])^4 [tex]x^{2}[/tex]. Then, pull terms out from under the radical, which will look like [tex]x^{2}[/tex][tex]\sqrt[4]{x^2}[/tex]. Next, rewrite [tex]\sqrt[4]{x^2}[/tex] as [tex]x^{2}[/tex][tex]\sqrt{} \sqrt{x}^2[/tex]. Finally, pull terms out from under the radical, assuming positive real numbers, which look like [tex]\sqrt[x^2]{x}[/tex], and this will simplify 4 sqrt x^10.

Now, simplify [tex]x^{2}[/tex]([tex]\sqrt[4]{x^2}[/tex] ). To simplify, rewrite [tex]\sqrt[4]{x^2}[/tex] as [tex]\sqrt{} \sqrt{x^2}[/tex]. Then, pull terms out from under the radical, assuming positive real numbers, and the final answer is [tex]\sqrt[x^2]{x}[/tex].

Finally, 4 sqrt x^10 is equivalent to [tex]x^{2}[/tex]([tex]\sqrt[4]{x^2}[/tex] ).

Answer:

B: VY = YB = YJ

Step-by-step explanation:

Looking at the options;

A) ∠VYB is not equal to ∠SJY because SJY is a straight line while ∠VYB is an angle.

B) VY = YB = YJ. This is true because they all start from Y which is the centre of the circle and they all terminate at the perimeter of the circle.

Thus,they are all equal to the radius and thus statement is true.

C) ∠SYV ≠ ∠SYB because there is no proof given that the angle of tilt is the same.

D) TX = MP = YJ is not true because TX and MP are chords which by inspection don't seem equal and neither the radius YJ appears to be equal to them.

E) ∠MJY ≠ ∠XSY because they have nothing in common in terms of angle.

Step-by-step explanation:

The required measure of the angle ∠JML  is given as 98°.

A quadrilateral is a four-sided shape as given in the picture in question.

Here,
∠KLM = ∠MJK = 103°
∠ JKL = 2×28 = 56°

The required measure of the ∠JML is given as,
A quadrilateral has 4 angles. The sum of its interior angles is 360 degrees. So the sum of the angle of the kite is equal to 360°

∠KLM + ∠ JKL + ∠MJK + ∠ JML = 360

103 + 56 + 103 + ∠JML = 360
∠JML = 98°

Thus, the required measure of the angle ∠JML  is given as 98°.

d is 18 times sqr root of 3

Answers:

sqrt is shorthand for "square root"

=====================================================

Explanation:

The smaller triangle on the left is a 45-45-90 triangle (aka isosceles right triangle). One special property of such triangles is that the legs are the same length, meaning a = c. Another special feature is that the hypotenuse is exactly sqrt(2) times that of the leg.

In other words, if x is the leg length, then x*sqrt(2) is the length of the hypotenuse. That means mean a = 18 in order for the hypotenuse to be 18*sqrt(2). This then leads to c = 18 as well.

--------------

The smaller triangle on the right side has a = 18 as the shorter leg, opposite the smallest angle (30 degrees). The hypotenuse b is twice that of the short leg, and this works because we're dealing with a 30-60-90 triangle. Therefore b = 2a = 2*18 = 36.

The longer leg d is equal to sqrt(3) times the short leg, ie,

d = a*sqrt(3)

d = 18*sqrt(3)

You could use the pythagorean theorem to solve for d like so:

a^2 + d^2 = b^2

18^2 + d^2 = 36^2

d^2 = 972

d = sqrt(972)

d = 18*sqrt(3)

I skipped a bunch of steps, but you get the idea.

Answer:

Step-by-step explanation:

Area of the inner circle = 3^2 π = 9 π

total area = 10^2 π = 100π

area of the shaded region

100π - 9 π = 91 π

The area of the shaded region is 91π square cm if the radius of the inner circle is 3 centimeters and the distance from the edge of the inner circle to the edge of the outer circle is 7 centimeters option (d) is correct.

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have:

The radius of the inner circle r = 3cm

The distance from the edge of the inner circle to the edge of the outer circle = 7 cm

So the radius of the outer circle = 7+3 = 10 cm

Area of the inner circle = π(3)²  = 9π square cm

Area of the outer circle = π(10)²  = 100π square cm

Area of the shaded region = 100π -9π = 91π square cm

Thus, the area of the shaded region is 91π square cm if the radius of the inner circle is 3 centimeters and the distance from the edge of the inner circle to the edge of the outer circle is 7 centimeters option (d) is correct.

Sn=3(1-1/2^n)

Step-by-step explanation:

The expression which defines [tex]S_{n}[/tex] is option c which is [tex]S_{n} =3(1-1/2){n}[/tex].

A geometric progression is basically a sequence in which all the terms have a common ratio. It is also known as G.P.

We have been given a sequence as 3/2+3/4+3/8+3/16+.....

If we carefully see the sequence then we will find that this sequence is a Geometric progression because there is a common ratio between all the terms that is 1/2.

Ratio of first and second term=3/4/3/2=1/2

We know that Sum of GP when n<1 is [tex]a(1-r^{n} )/1-r[/tex]

we have to just put the value of =3/2 and r=1/2 in the above formula.

[tex]S_{n}[/tex]=3/2(1-[tex]1/2^{n}[/tex])/1-1/2

=3/2(1-[tex]1/2^{n}[/tex])/1/2

=3*2/2(1-[tex]1/2^{n}[/tex])

=3(1-[tex]1/2^{n}[/tex])

Hence the expression which denotes [tex]S_{n}[/tex] is 3(1-[tex]1/2^{n}[/tex]).

Here's the solution :

In a sphere,

[tex] \boxed{ \mathsf{surface \: \: area = 4\pi {r}^{2} }}[/tex]

now, let's solve :

hence, correct answer is B. 100π unit²

The surface area of the sphere is 100 π unit².

The correct option is B.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

We have,

Radius of Sphere= 5 unit

Now, the formula for Surface area of Sphere is

= 4πr²

= 4 (3.14) (5)(5)

= 4 x 3.14 x 25

= 314

= 10 π unit²

Answer: Choice B

n-4 = 32

==============================================

Explanation:

We start with n students. The n is a placeholder for any positive whole number. After 4 of them drop the class, we're left with n-4 students.

Then we set that equal to 32, since that's the number of students left over.

This leads to the answer of n-4 = 32

Solving this equation gets us n = 36. We add 4 to both sides.
