Write each equation in logarithmic form.
10⁻²=0.01
The equation in logarithmic form is log₁₀(0.01)=−2.
Given the equation is:
10⁻²=0.01
The fundamental logarithmic function has the notation f(x) = log(r) y = log(x), where a > 0. The exponential function ay = x's inverse is represented by this. The common logarithm (log) or natural logarithm (ln) are examples of log functions (log).
Convert the exponential equation to a logarithmic equation using the logarithm base (10)of the right side (0.01) equals the exponent (−2).
A popular method for changing a mathematical equation from one form to another is to transform it from exponential to log form. The exponential form an x = N is translated into the logarithmic form
Log aⁿ= x.The exponent of x, which is equal to N, has the exponential form a to it is converted to the logarithm of a number N to the base of a, which is equal to x.

(i) 3x - 2y = 4
(ii) 2x-b-4c
(iv) 5(x-3)= 2y
(v) 3y=-2
(iii) 5x -4 = I
(vi) xy = xz + yz
'x' in each expression is as follows:
x = (4+2y)/3x = (b + 4c)/2x = (2y + 15)/5y = -2/3x = (l + 4)/5xy/xz = yzWhat are variables?A variable in mathematics is an alphabet or term that stands in for an unknown quantity, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are used. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants. Typically, it is a letter like x or y. Example: The variable in x + 2 = 6 is x. We can find x = 4 by solving the x + 2 = 6 situation.So, the value of 'x' in each expression:
(i) 3x - 2y = 4 ⇒ 3x = 4+2y ⇒ x = (4+2y)/3(ii) 2x-b-4c ⇒ 2x = b + 4c ⇒ x = (b + 4c)/2(iii) 5(x-3)= 2y ⇒ 5x = 2y + 15 ⇒ x = (2y + 15)/5(iv) 3y = -2 ⇒ y = -2/3(v) 5x -4 = I ⇒ 5x = l + 4 ⇒ x = (l + 4)/5(vi) xy = xz + yz ⇒ xy/xz = yzTherefore, 'x' in each expression is as follows:
x = (4+2y)/3x = (b + 4c)/2x = (2y + 15)/5y = -2/3x = (l + 4)/5xy/xz = yzKnow more about variables here:

If each person receive exactly one bracelet then , the number of ways= 4 x 3 x 2 x 1 = 24
If all bracelet received by one person and other have no bracelet 4 ways
If one person receive 2 bracelet and other two received by any other=
144 way.
If two person gets two bracelet each and other two have no bracelet= 36 ways

Carlo, having a mass of 50kg, running to the next classroom for his next subject. If his running speed is 10m/s, what is his kinetic energy?
Answer:
Kinetic energy = 2500 J
Step-by-step explanation:
To calculate the kinetic energy of an object, we can use the following formula:
[tex]\boxed{E_k = \frac{1}{2}mv^2}[/tex],
where:
[tex]E_k[/tex] = kinetic energy
m = mass of the object
v = speed of the object
In this question, we are told that Carlo's mass is 50 kg and his speed is 10 m/s. Using this information and the formula above, we can calculate Carlo's kinetic energy:
[tex]E_k = \frac{1}{2} \times 50 \times (10)^2[/tex]
[tex]= \frac{1}{2} \times 50 \times 100[/tex]
[tex]= \bf 2500 \: J[/tex]
Therefore, Carlo's kinetic energy is 2500 J.

Step-by-step explanation:
The distance between 2 points in a 2_D Cartesian coordinate can be determined by the distance formula
[tex]d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex]
where [tex](x_1, y_1) \mathrm{\;and\:} (x_2, y_2)[/tex] are the coordinates of the two points
This is also called Euclidean distance between the two points
Here coordinates of B are (-4, 6) and those of D are (-3, -3)
So distance between them
[tex]d = \sqrt {(-3 - (-4))^2 + (-3 - 6)^2}[/tex]
[tex]= \sqrt {(1)^2 + (-9)^2}[/tex]
[tex]= \sqrt {{1} + {81}}[/tex]

Suppose you invest a dollars to earn an annual interest rate of r percent (as a decimal). After t years, the value of the investment with interest compounded yearly is A(t)=a(1+r) t . The value with interest compounded continuously is A(t)=a . e rt
a. Explain why you can call e r-1 the effective annual interest rate for the continuous compounding.
For continuous compounding, the effective annual interest rate is e^r - 1.
What do we mean by continuous compounding formula?When an issue expressly states that the amount is "constantly compounded," the continuous compounding formula should be used.This formula employs the mathematical constant "e," whose value is approximately 2.7182818.The following is the continuous compounding formula:
A = Pe^rtWhere P equals the starting sum, A is the total sum, r equals the interest rate, t = time and e is a mathematical constant.So,
Given: A(t) = a(1+r)^t and A(t) = a.e^rt.
Let the effective rate be R.
Then,
a(1+R)^t = a.e^rt(1+R)^t = e^rt(1+R) = e^rR = e^r - 1Therefore, for continuous compounding, the effective annual interest rate is e^r - 1.

Identify the percentage of growth or decay for the exponential function y = 104(2.05) x
The percentage of decay for the exponential function: y = 104(2.05) x is 105%.
How to illustrate the information?This equation represents exponential decay. Whenever the base is less than 1, the function represents decay. When the base is greater than 1, the function represents growth. In this case, the base is 2.05 which is 1.05 than 1, representing growth.
The formula for exponential decay is y=a(1-r)x.
r is the decay rate, expressed as a decimal.
In this case, r = 2.05 - 1 = 1.05 which represents 105%.
Therefore, the percentage of decay for the exponential function is 105%.

How can Mackenzie find the amount of flour she used?
Mackenzie can find the amount of flour used by using subtraction. She should subtract the flour left in the bag from 10 pounds.
Subtraction is one of the four basic mathematical operations.
It is used to calculate the amount left after a quantity is reduced.
When two variables are subtracted we use the following notation '-' .
Let us consider two variables x and y such that x is subtracted from y then mathematically it is denoted by y - x .
Mackenzie used some flour to bake bread. To calculate the amount she used from 10 pound bag , first she will have to find the amount of flour left in the bag.

Answer:
170 ft²
Step-by-step explanation:
4ft = 48 in
You then multiply 48 by each given side.
48 in · 4.25in = 204 in
Divide by 12 to get answer in feet.
204 in ÷ 12 = 17
So the actual length of the side labeled 4.25 in is 17 ft.
48 · 2.5 = 120
Divide by 12 to get the answer in feet.
120 ÷ 12 = 10
The actual length of the side labeled 2.5in is 10 ft.
Area= L x W
Area= 17ft · 10ft = 170 ft²
A commuter train has 8 cars with a maximum occupancy of 56 passengers each and 3 cars with a maximum occupancy of 40 passengers each
The maximum occupancy of the commuter train is 568 passengers
How to determine the maximum occupancy of the commuter train?The given parameters can be represented using the following table of values
1 2
Passenger 56 40
Cars 8 3
The maximum occupancy of the commuter train is then calculated as
Maximum occupancy = Sum of (Passengers * Cars)
So, we have
Maximum occupancy = 56 * 8 + 40 * 3
Evaluate the products in the above equation
So, we have
Maximum occupancy = 448 + 120
Evaluate the sum in the above equation
So, we have
Maximum occupancy = 568
