The required logarithm form is -2log5

Given the exponential form of an equation expressed as;

[tex](5)^{-2} = 1/25[/tex]

For us to change the exponential form into logarithmic equation, first we need to identify the base, move it to the other side of the expression and then take the logarithm

Take the logarithm of both sides

[tex]= log(5)^{-2} \\=-2log5\\[/tex]

Hence the required logarithm form is -2log5

Answer:

d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))

Step-by-step explanation:

To find the derivative of f(t), we have to find the derivative of each component of the function to make it easier.

d(8/(t^7))/dt = d(8xt^-7)/dt = –7 x 8 x t^-8 = –56t^-8 = -56/(t^8)

d(5/(t^(1/6)))/dt = –(1/6) x 5 x t^(-7/6) = –(5/6)/t^(7/6)

d(3t^4)/dt = 4 x 3 x t^3 = 12t^3

d(t²)/dt = 2t

d(t^⅓)/dt = ⅓t^(-2/3) = (1/3)t^(2/3))

d(12)/dt = 0.

Therefore,

d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))

The properties of equality used to solve the equation 3x+5=14 are subtraction and division.

The properties of equality, which can be used to solve any equation, include:

However, we can determine if the solution to the equation and the properties are correct by substituting the variable's value into the equation using the substitution property of equality.

Check:

Given that 3x+5 = 14

3x = 14 - 5    Subtraction

3x = 9

x = 3 (9/3)    Division

Thus, in equation 3x+5=14, the properties of equality that would solve it are subtraction and division.

Answer: 0.1346

Step-by-step explanation:

Number of vowels = 5 vowels

Number of consonants = 25

For us to calculate the probability of selecting two vowels one after another, we have to select the first vowels which will give a probability of 5/40, then we select the second vowel which will be 4/24 since there'll be 4 vowels left 39 alpahabets.

Therefore, probability of selecting two vowels one after another will be:

= 15/40 × 14/39

= 3/8 × 14/39

= 0.1346

Answer:

The 26% solution should she use is explained below in detailed explanation.

Step-by-step explanation:

Assumed there be 10 percent of x liters of acid solution

Assumed there be 26 percent of y liters of acid solution

provided Information

A chemist needed to combine a 10 percent acid solution with a 26 percent acid solution to obtain 16 liters of a 14 percent acid solution

So, ( 10 / 100 )*x + ( 26 / 100 )*y = ( 14 / 100 )*16

=> 0.1*x + 0.26*y = 0.14*16

=> 0.1*x + 0.26*y = 2.24 ....................... eq 1

x + y = 16 ......................... eq 2

Multiply ( 0.1 ) in both side in eq 2

=> 0.1*x + 0.1*y = 0.1*16

=> 0.1*x + 0.1*y = 1.6 ......................... eq 3

Subtract eq 3 from eq 1

0.1*x - 0.1*x + 0.26*y - 0.1*y = 2.24 - 1.6

=> 0.16*y = 0.64

=> x = 0.64 / 0.16

=> y = 4

So, 4 liters of 26% solution she should utilized

Answer: -2 and 4

Step-by-step: You see the horizontal line? now look at the the numbers -2 and 4 on that line. Notice how the line passes through them? those are your x-intercepts.

The required coordinates of the x-intercepts of the parabola are (0, -2) and (0, 4).

The x-intercept is defined as an intercept that is located at the x-axis of the plane, which is the location or coordinates from where the line crosses.

We have to determine the coordinates of x-intercepts and y-intercepts that would function in the given graph.

The parabola of the graph is given in the question

A horizontal axis, or x-axis, and a vertical axis, or y-axis, are present in a 2-dimensional coordinate graph. Intercepts are the points (0, -2) and (0, 4) here lines representing a range of values intersect these axes.

Therefore, the required coordinates of the x-intercepts of the parabola are (0, -2) and (0, 4).
