Solve the exponential equation.<br><br> 1/16 = 64x<br><br> a. -2/3<br> b. 2/3<br> c. 3/2
valkas [14]
We have that
1/16 = 64<span>^x
applying log both sides
log(1/16)=log(</span>64^x)
log 1-log16=x*log64
-log 16=x*log 64
divide by log 64 both sides
x=-log 16/log 64
log 16=log 2^4-----> 4*log 2
log 64=log 2^6-----> 6*log 2
-log 16/log 64=(-4*log 2)/(6*log 2)-----> -4/6------> -2/3

the answer is 
x=-2/3

What is the sum of the polynomials?
vivado [14]

The answer is 3x^2 + 6x + 4 (the second one)

Let's start by removing the parenthesis to get 6x + 7 + x^2 + 2x^2 - 3

Then, let's combine like terms (terms with the same variable and exponent) to get 3x^2 + 6x + 4

This is an answer in the multiple choice, so the answer is 3x^2 + 6x + 4 (the second one)

the two lines represent the amount of water, over time, in two tanks that are the same size. Which container is filling more qui
uranmaximum [27]

The missing figure is attached down

Answer:

Container A is filling more quickly

Step-by-step explanation:

<em>Let us explain the linear relation</em>

The linear equation is y = m x + b, where

  • m is the slope of the line which represents the rate of change (change in y/change in x)
  • b is the y-intercept which means the initial amount of y (at x = 0)

<em>If a line represents the amount of water over time, then it represents the rate of filling of the water</em>

∵ There are two containers A and B that have the same size

∵ The two lines represent the amount of water over time in

    containers A and B

∴ The slopes of the lines represent the rat of water in the tanks

→ That means the greater slope represents the greater rate

∵ The greater the slope, the steeper the line

∴ The container that represented by the steeper the line is filling quickly

→ The line represents container A is steeper more than the line

    represents container B

∴ Container A is filling more quickly
