Answer:

The value of x = 64. Hence, option A is correct.

Step-by-step Explanation:

$\log _4\left(x\right)=3$

We know that the rule:

$y\:=\:\log _a\left(x\right)$

can be represented as:

$x\:=\:a^y$

so

$\log _4\left(x\right)=3$

4³=x

x = 64

Thus, the value of x = 64. Hence, option A is correct.

What is the solution to the system of equation?<br> -3x-4y-32= -7 <br> 2x-6y+2=3 <br> 5x-2y+5z=9

sertanlavr [38]

<span>Simplifying 8x + 336 = 336 + -3x Reorder the terms: 336 + 8x = 336 + -3x Add '-336' to each side of the equation. 336 + -336 + 8x = 336 + -336 + -3x Combine like terms: 336 + -336 = 0 0 + 8x = 336 + -336 + -3x 8x = 336 + -336 + -3x Combine like terms: 336 + -336 = 0 8x = 0 + -3x 8x = -3x Solving 8x = -3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3x' to each side of the equation. 8x + 3x = -3x + 3x Combine like terms: 8x + 3x = 11x 11x = -3x + 3x Combine like terms: -3x + 3x = 0 11x = 0 Divide each side by '11'. x = 0 Simplifying x = 0</span>

"Assuming a current world population of 8 billion people, an annual growth rate of 1.8% per year, and a worst-case scenario of e

Ganezh [65]

Answer:

The world population will be 11.64 billions in 21 years.

Step-by-step explanation:

Initial population = 8 billion

Growth rate = 1.8% per year =0.018

Time = 21 years

We are supposed to find what will the world population be in 21 years

Formula : $y = a (1+r)^t$

y = population after t years

r = rate of interest in decimals

t = time in years

Substitute the values :

$y =8(1+0.018)^{21}$

$y =11.635$

Hence the world population will be 11.64 billions in 21 years.

A flying disc has a 5 ⅖ inch radius. What is its approximate circumference, rounded to the nearest inch?

Ivenika [448]

<h2>Circumference of flying disc is 34 inches</h2><h3><u>Solution:</u></h3>

Given that,

$Radius = 5\frac{2}{5}\ inches = \frac{27}{5}\ inches$

To find: circumference

<h3><u>The circumference of circle is given as:</u></h3>

$C = 2 \pi r$

Where, r is the radius of disc

Therefore,

$C = 2 \times 3.14 \times \frac{27}{5}\\\\C = 6.28 \times 5.4\\\\C = 33.912$

$C \approx 34$

Thus the circumference of flying disc is 34 inches
