Using the law of indices, [tex]1024^{\frac{2}{5} } = 16[/tex]

The expression can be solved using the law of indices as follows:

[tex]1024^{\frac{2}{5} }[/tex]

using law of indices, involving bracket.

Brackets with indices are where we have a term inside a bracket with an index (or power) outside of the bracket.

To do this we can raise everything inside the bracket to the power.

[tex](a^{b} )^{x} = a^{bx}[/tex]

Therefore,

1024 = 2¹⁰

Hence,

[tex]2^{\frac{2}{5} (10)} = 2^{\frac{20}{5} } = 2^{4} = 16[/tex]

Therefore,

[tex]1024^{\frac{2}{5} } = 16[/tex]

The surface area of the sphere is 84453.44 yards².

We are given that:

the ride goes around the widest circle of the sphere whose circumference is =  514.96 yard.

The widest circle of the sphere is the plane contains the sphere's center

The circumference of the widest circle is:

C = 2 π r

where r is radius of the sphere.

The surface area of the sphere is defined as:

A = 4 π r²

where  r is radius of the sphere.

So, we get that:

514.96 =2 π r

514.96= 2 × 3.14 × r

r = 514.96 ÷ (2 × 3.14)

r = 514.96 ÷ 6.28

Surface Area A = 4 π r²

A = 4 × 3.14 × (514.96 ÷ 6.28) × (514.96÷ 6.28)

A = 84453.44 yards²

Therefore, we get that, the surface area of the sphere is 84453.44 yards².

The simplified form of the given expression ( a⁴b²c³d ) / acbd is equal to (a³bc² ) .

As given in the question,

Given expression :

 ( a⁴b²c³d ) / acbd

Simplified form of the given expression using rules of power and exponents:

Since this is division of algebraic fractions, the index (power or exponent) of the like literals in the numerator and denominator are to be subtracted. Thus index of variable a reduces from 4 to 1. Similarly index of variable b reduces from 2 to 1 and that of c reduces from 3 to 2. Lastly variable d remains in the denominator as there is no corresponding factor in the numerator.

( a⁴b²c³d ) / acbd

= (a⁴⁻¹ )(b²⁻¹ )(c³⁻¹ )(d¹⁻¹)

= a³ bc²d⁰

= a³bc²

Therefore, the simplified form of the given expression ( a⁴b²c³d ) / acbd is equal to (a³bc² ) .

 (-7,∞) &  (−∞, 1/2] are the interval notation.

What is interval notation in math?

8x-5>=6x-1 or 4+4x<=3x-3

8x-5 ≥6x-1

8x - 5 ≥ 6x - 1

8x - 6x ≥  5 - 1

 2x ≥  1

   x ≥  1/2

Therefore, x could be any number less than or equal to 1/2. In interval notation, this looks like

 (−∞, 1/2]

4+4x ≤ 3x-3

4 + 4x ≤  3x - 3

4x - 3x ≤  -3 - 4

   x ≤  -7

Therefore, x could be any number less than -7 , but x couldn't be -7, since that would make the two sides of the inequality equal. In interval notation, this looks like:

WS bisects angle BWV, m ∠BWS = 36° , then the measure of angle

m ∠BWV is equal to 72°.

As given in the question,

Measure of given angle :

m ∠BWS =36°   ____(1)

let 'x' be the measure of angle BWV

WS bisects angle BWV.

⇒ m ∠BWS= m ∠SWV

⇒ m ∠SWV=36° ____(2)

Also , m ∠BWV is equal to the sum of the measure of ∠ BWS and ∠SWV.

⇒ m ∠BWV =m ∠BWS + m ∠SWV

Substitute the value of m∠ BWS and m ∠SWV from (1) and (2),

⇒ m ∠BWV=36° + 36°

⇒m ∠BWV=72°

Therefore, WS bisects angle BWV, m ∠BWS=36° , then the measure of angle m ∠BWV is equal to 72°.

The Distance between line ℓ and the point j (-5,-1) is 8units.

The distance between a point PP and a line LL is the shortest distance between PP and LL; it is the minimum length required to move from point PP to a point on LL. In fact, this path of minimum length can be shown to be a line segment perpendicular to LL. The distance d can then be defined as the length of the line segment that has PP as an endpoint and is perpendicular to LL.

We know that the distance d between a point (x1,y1) and a line having equation in form of ax+by+c=0 can be expressed as,

[tex]d = \frac{|ax1+by1+c|}{\sqrt{(a^2+b^2)} }[/tex]

So, we have given that equation of line

y = 7

y-7=0

Point j = (-5,-1)

So, Distance between point j and line = d

d = [tex]\frac{|0(-5)+1(-1)-7|}{\sqrt{(0^2+1^2)} }[/tex]

d = [tex]\frac{8}{\sqrt{1} }[/tex]

d = 8 units

In mathematics, an operation is a function that transforms 0-n operands or parameters into a known output value. The number of operands affects how complicated the operation is. 90.95 feet per second equates to 62 miles per hour.

An operation in mathematics is the function that converts 0–n parameters or operands into definite output value. The complexity of operation depends on how many operands there are.

The operations that are the most frequently studied are binary operations (i.e., operations of the arity 2), which include addition and multiplication, and the unary operations (i.e., operations of the arity 1), which include additive inverse and the multiplicative inverse. A zero-arity operation, also known as nullary operation, is a constant. An illustration of ternary operation, also known as an operation of arity 3, is the mixed product.

Usually, it is considered that arity is constrained. Even so, the infinitary operations are occasionally considered, in which case "normal" finite dimensionality operations are referred to as finiteary operations.

A partial operation is described as being similar to operation but using a partial function in place of a function.

The correct answer to the task 0.80 divided by 50 given above is 0.016

When we are trying to find the number of times a number can be obtained in another number, we use the term "division" to describe the mathematical expression. The division can be represented as ÷

For instance, the division of 0.80 by 50 is represented and solved below:

0.80 ÷ 50 = 0.016

It can also be represented like this:

0.80 / 50 = 0.016.

Another example of division of numbers is:

Using the z-distribution, the 95% confidence interval for the proportion of unsatisfactory meals is given by:

(0.0553, 0.0647).

A confidence interval of proportions is given by the following rule:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The estimate and the sample size of the interval are given as follows:

[tex]\pi = \frac{600}{10000} = 0.06, n = 10000[/tex]

The lower bound of the interval is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.06 - 1.96\sqrt{\frac{0.06(0.94)}{10000}} = 0.0553[/tex]

The upper bound of the interval is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.06 + 1.96\sqrt{\frac{0.06(0.94)}{10000}} = 0.0647[/tex]

Answer:x=1

Step-by-step explanation:

you would have to distribute the 5 into the (x+4)

then it would be

5x+20-3^2=2^4

then do the exponents

5x+20-9+16

then add 9 by both sides

5x+20=25

then subtract 20 on both sides

5x=5

then divide 5 on both sides

x=1

then check your work by putting 1 for x and you get 2^4=16

Answer:

Step-by-step explanation:

find x :

5( x + 4 ) - 3^2 = 2^4

5x + 20 - 9 = 16

5x = 16 - 20 + 9

5x = 5

x = 5 : 5

x = 1

5(1 + 4) - 3^2 = 2 ^4

25 - 9 = 16

Answer:

The measure of the largest angle is 145°

Step-by-step explanation:

Since the angles form a linear pair taking two angles that add to 180 and solving for x will give you the answer. the sentence "One angle is 5 more than four times the size of the other angle." your equation should look like this:

5 + 4x. the other angle uses the variable x. So the equation 5 + 4x + x = 180 should result in x = 35. That saying, the smaller angle is 35 and to find the larger angle either plug in x or subtract 180-35. both shoukd result in 145° which is the larger angle.

I'm guessing the whole question is: "A car drives 283.5 miles in 4.5 hours. Assuming that the distance traveled directly with the time traveled, how far will the car travel in 7 hours?"

Step-by-step explanation:

If so, here's the answer:

441 miles will be traveled in 7 hours

You could find the speed in mph

To do that, divide 283.5 by 4.5 which gives us 63

because [tex]\frac{283.5 miles}{4.5 hours}[/tex] divide to get the 4.5 hours into 1 hour so, [tex]\frac{283.5/4.5}{1}[/tex]

63 mph times 7 hours = 441

Answer:

4 inches

Step-by-step explanation:

the cube has a volume (V) calculated as

V = s³ ( s is the side length )

given V  = 64 , then

s³ = 64 ( take the cube root of both sides )

s = [tex]\sqrt[3]{64}[/tex] = 4

side length is then 4 inches

The given function y = x³ is not a linear function but a cubic function.

For the given function;

y = x.x.x

This, can be written, after adding the power of x as;

y = x³

Now, put x = 1; y = 1

Put x = 2; y = 8

Put x = 3; y = 27

This will not form a straight line but a cubical curve.

As, the function is not changing linearly but cubical.

Thus, the function is not linear function.
