Step-by-step explanation:

C

Answer:

if you divide both sides of -5x > 0 you get z > 0. This is incorrect because if you choose a value from the possible solutions such as z=6 and substitute it into the original equation you get -30 > 0, which is not true

The solutions which satisfy the equation A = 256ˣ are

Option B. 4⁴ˣ

Option D. 16²ˣ

Option E. 2⁸ˣ

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by A = 256ˣ

a)

The value of equation B = 8^2x

B = 8²ˣ

On simplifying the equation , we get

B = 8²⁽ˣ⁾

B = 64ˣ

And the value of B ≠ A

b)

The value of equation B = 4^4x

B = 4⁴ˣ

On simplifying the equation , we get

B = 4⁴⁽ˣ⁾

B = 256ˣ

And the value of B = A

c)

The value of equation B = (64^x)^2

B = (64ˣ)²

On simplifying the equation , we get

B = 64²⁽ˣ⁾

B = 4096ˣ

And the value of B ≠ A

d)

The value of equation B = (16^x)^2

B = (16ˣ)²

On simplifying the equation , we get

B = 16²⁽ˣ⁾

B = 256ˣ

And the value of B = A

e)

The value of equation B = 2^8x​

B = (2⁸)ˣ

On simplifying the equation , we get

B = 256⁽ˣ⁾

And the value of B = A

Hence , the equations which satisfy are

Option B. 4⁴ˣ

Option D. 16²ˣ

Option E. 2⁸ˣ

Answer:

24.5%

Step-by-step explanation:

Simple Interest = (principal×rate×time)÷100. *Brackets First*

Transpose the formula to make rate the subject: rate= (100×simple interest) ÷ (principal×time).

Plug in values: rate = (100×37975) ÷ (31000×5).

The result is 24.5%.

Answer:

Step-by-step explanation:

The mnemonic SOH CAH TOA was created to help you remember the relevant trig relationships. It is intended to remind you ...

  Sin = Opposite/Hypotenuse

  sin(θ) = 4/5

  Cos = Adjacent/Hypotenuse

  cos(θ) = 3/5

  Tan = Opposite/Adjacent

  tan(θ) = 4/3

__

In a right triangle, the opposite side (PQ) is the one that is not part of the angle (∠R = θ). The adjacent side (QR) is the shorter side that makes up the acute angle. The longest side (PR) is the hypotenuse.

Answer:

Hii, the answer B. 46

Step-by-step explanation:

x+ 53 = 99

So to find what x equals we just do simple subtraction

99 - 53 = 46

so x = 46

Hope this helps!

Answer:

x=36

Step-by-step explanation:

if PQR is isosceles then

PRQ will also equal 69 degrees

straight line = 180 degrees

so if PRQ is 69, then

PRS = 180-69

= 111 degrees

now to find x , since we have two angles within that triangle

180 - 111 - 33 = 36 degrees

Step-by-step explanation:

Given that,

The radius of circle, r = 50 feet

The central angle, [tex]\theta=5\ radian[/tex]

We need to find the area of the sector of a circle. The formula for the area of sector is given by :

[tex]A=\dfrac{1}{2}r^2\theta\\\\=\dfrac{1}{2}\times 50^2\times 5\\\\A=6250\ feet^2[/tex]

So, the area f the sector of the circle is [tex]6250\ feet^2[/tex].

Answer:

  5 (all of them)

Step-by-step explanation:

The sums of digits are ...

  6+4+8 = 18

  8+4+6 = 18

  1+2+6 = 9

  6+1+2 = 9

  5+7+6 = 18

When the sum of digits is a multiple of 9, the number is divisible by 3 and 9.

When the number is also even (as all of these are), it is also divisible by 6.

All 5 of these numbers are divisible by 3, 6, and 9.

Answer:

All 5 of them.

Answer:

A. is incorrect. He has to divide 76 by 19, instead of subtracting 19 to 76.

B. This equation has one solution. v=4

Step-by-step explanation:

Hi, Martin’s answer is incorrect.

A. He has to divide 76 by 19, instead of subtract 19 to 76.

The correct steps are:

19v = 76  

Since 19 is multiplying the variable, to eliminate it we have to divide by 19.

v = 76/19

v = 4

B. This equation has one solution. It’s v=4
