Solution of exponential equation is , x = [tex]800. 7^4[/tex]
What is exponential equation ?In, mathematics a exponential equation or exponential function is inverse of logarithmic function. That means, we can easily convert the logarithmic function into exponential function and vice versa. The basic form of the logarithm function can be written as [tex]a^x[/tex] .
where, a = the base of function
x = main expression
Mathematically, if [tex]log_aN = x[/tex] is an logarithmic function then, this can be converted to exponential function as [tex]a^x = N[/tex].
There are many formulas that are given to us for solving several simple and complex problems based on exponential functions and exponential equations.
Some important formulas of exponential :
[tex]a^x . a^y = a^{x+y}[/tex][tex]\frac{a^x}{a^y} = a^{x-y}[/tex][tex]a^x.b^x=(ab)^x[/tex][tex](a^x)^y = a^{xy}[/tex][tex]a^{-x} = \frac{1}{a^x}[/tex]According to given statement,
[tex]7^{-4} x = 800[/tex]
=> [tex]\frac{1}{7^4} x = 800[/tex]
=> [tex]x = 800 . 7^4[/tex]
Thus solution for this equation is x = [tex]800. 7^4[/tex]

A Gallup poll asked americans how many hours of sleep they usually get. The difference between the percent of adults who slept s’more than the recommended amount of time and the percent who slept less than the recommended amount of time is 3%. In total, these groups make up 25% of the population. What percent of the population sleeps more than the recommended number of hours, and what percent sleeps less?
The percent of the population sleeps more than the recommended number of hours will be 30%.
How to illustrate the information?From the information, it should be noted that the difference between the percent of adults who slept more than the recommended amount of time and the percent who slept less than the recommended amount of time is 3%.
It should be noted that this was 25% of the population.
Therefore, the percent of the population sleeps more than the recommended number of hours will be:

Slope intercept form (-6,19) and (3,-2)
Answer:
[tex]y = -\dfrac{7}{3}x +5[/tex]
Step-by-step explanation:
The general equation of a line in slope-intercept form is
y = mx + b
where m = slope and b = y-intercept is rise over run
[tex]m = \dfrac {(y_{2} - y_{1})} {(x_{2} - x_{1})}[/tex]
where (x₁, y₁) and (x₂, y₂) are any two points on the line
[tex]m = \dfrac{-2 - 19}{3 - (-6)}\\\\[/tex]
[tex]\\\\m= \dfrac{-21}{9}[/tex]
[tex]m = -\dfrac{7}{3}[/tex]
So slope-intercept form is
[tex]y = -\dfrac{7}{3}x +b\\\\[/tex]
[tex]-2 = -\dfrac{7}{3}\cdot 3 +b\\\\\\\\-2 = -7 + b\\\\[/tex]
or 7 -2 = b
==> b = 5
[tex]y = -\dfrac{7}{3}x +5[/tex]

p≤49 is the inequality to represent the situation.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
Given that a typical paper bag at a grocery store cannot hold more than 49 pounds.
Let p represent the number of pounds a typical paper bag can hold.
We have to find the inequality to represent the situation
As grocery store cannot hold more than 49 pounds which means it holds less than or equal to 49.
p≤49
Hence, p≤49 is the inequality to represent the situation.

If Lourdes buys 12 packs of paper in terms of 3 packs each she has to pay 0.5 dollars more.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given Lourdes can buy 3-packs of paper for $10.50.
∴ The cost of per pack of paper is = (10.50/3) = $3.5.
In this case, if she can buy 4-packs of paper for $13.50,
The cost per paper pack is = (13.50/4) = $3.375.
To buy 12 packs in terms of 3 packs each Lourdes has to pay,
(3.5×12) dollars.
= 42 dollars.
To buy 12 packs of paper in terms of 4 packs each she has to pay,

Angles of Triangles #3: Find the angles below
All the angles in the given diagram are;
∠5 = 81°
∠1 = 128°
∠2 = 52°
∠3 = 47°
∠4 = 133°
How to find Congruent Angles?
We are given different angles. Thus;
52 + ∠5 + 47 = 180
This is because sum of angles on a straight line is 180°. Thus;
99 + ∠5 = 180
∠5 = 180 - 99
∠5 = 81°
∠1 = ∠5 + 47° because of the definition of corresponding angles. Thus;
∠1 = 81° + 47°
∠1 = 128°
∠2 = 52° because they are corresponding angles.
∠3 = 47° because they are corresponding angles.
∠4 = 180 - 47° because sum of angles on a straight line is 180°.

NEED SOON
The reasonable area for the square piece of plywood he must purchase if he only wants to make one cut in the wood would be 216 sq inches.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We have been given that the flag is to be 18 inches by 12 inches, then;
The area of the rectangle = length × Width
The area of the rectangle = 18 x 12
= 216
Since the area of flag will be equal to area for the square piece of plywood.
The area of a square of side length l is given by l squared;
A(l) = l²
216 = 14.6²
Hence, the reasonable area for the square piece of plywood he must purchase if he only wants to make one cut in the wood would be 216 sq inches.
