Step-by-step explanation:
300 grams-24 hour= 276 so i think u just need to keep doing this till it gets to 206.4
The equation which represents the number of hours will be ln(206.4) = 1200ln(0.014).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a candle weighs 300 grams (g). Each hour the candle is lit, it burns 4 g of its wax. a. Leth be the number of hours the candle burns.
The equation for the number of hours will be calculated as,
[tex]h=300\times (0.014)^h[/tex]
lnh= 300 x ln(0.014)
Therefore, the equation which represents the number of hours will be ln(206.4) = 1200ln(0.014).

Find three consecutive even integers such that the sum of the least integer and the middle integer is 24 more than the greatest integer.
Answer:
26, 28, 30
Step-by-step explanation:
there is a difference of 2 between consecutive even integers
let the integers be n , n + 2 , n + 4 , then
n + n+ 2 = n + 4 + 24
2n + 2 = n + 28 ( subtract n from both sides )
n + 2 = 28 ( subtract 2 from both sides )
n = 26
n + 2 = 26 + 2 = 28
n + 4 = 26 + 4 = 30
the 3 consecutive even integers are 26 , 28 , 30
The revenue for a business, as a function of units produced, x, is shown below by R(x). C(x) represents the cost of producing x units. Calculate the profit function and then determine how many units must be produced for the business to break even.
R(x) = 24x
C(x) = 17x + 161
By calculating profit function to break even, the company needs to produce 23 units.
What is meant by profit function?The amount received when a good or service is sold for a price is referred to as revenue. The cost of a product or service is the amount spent on its sale. Profit is defined as the difference between revenue and costs. A profit function is a relationship that shows the difference between the cost and revenue functions. The graph of a profit function can show the best combination of revenue and costs to produce the most profit. This is known as optimization.
Profit is defined as revenue less costs. This means that there is a profit function, P(x).
P(x) = R(x) - C(x)
Breaking even is the point at which revenue begins to exceed costs. It is thus the point at which P(x) = 0. Because these are all linear functions, you know that the business will be profitable after that point.
P(x) = 0
R(x) - C(x) = 0
R(x) = 24x
C(x) = 17x + 161
From the above equation,
R(x)=C(x)
24x=17x+161
7x=161
x=161/7
x=23
For the company to break even, 23 units must be produced.

Nina is buying 8 avocados. each avocados weighs 8 oz. how much will they cost her if avocados cos $2.99 per pound
If avocados costs $2.99per pound, Nina will be paying $1.495
How to solve for the amount Nina would payThe information given in the problem shows that
avocado's have their price in pounds hence we convert the quantity given to pounds
1 pound = 16 ounces
? = 8 ounces
cross multiplying
8 * 1 = ? * 16
? = 8 / 16
? = 1/2
hence 8 ounces is 0.5 pounds
Then the cost of 0.5 pounds of avocados will be solved for
1 pounds = $2.99
0.5 pounds = ?
cross multiplying
? = 0.5 * 2.99
? = $1.495

From the chart, estimate (roughly) the number of transistors per IC in 2016. Using your estimate and Moore's Law, what would you predict the number of transistors per IC to be in 2040?
Please explain
The estimates for the number of transistors per IC, using an exponential function, are given as follows:
2016: 16,777,216,000.2040: 6.87 x 10¹³.What is the format of an exponential function?An exponential function has the general format presented as follows:
[tex]y = ab^\frac{x}{n}[/tex]
In which the parameters of the function are listed as follows:
a is the initial value of the function.b is the rate of change of the function.n is the period relative to the rate of change.By Moore's Law, the number of transistors per IC doubles every two years, hence the values of parameters b and n are both two, that is:
b = 2, n = 2.
We take 1972 as the reference year, when the amount was of 4000 transistors per IC, hence the value of parameter a is given as follows:
a = 4000.
Thus the equation is:
[tex]A(t) = 4000(2)^{\frac{t}{2}}[/tex]
Giving the number of transistors per IC in t years after the reference year of 1972.
2016 was 44 years after 1972, hence the estimate for the amount of transistors by IC was of:
[tex]A(44) = 4000(2)^{\frac{44}{2}} = 16,777,216,000[/tex]
2040 will be 68 years after 1972, hence the estimate for the amount of transistors by IC is of:
[tex]A(68) = 4000(2)^{\frac{68}{2}} = 6.87 \times 10^{13}[/tex]

ordered pairs solution for 7x+2y>-26
The ordered pairs that are solutions of the inequality are of the form:
(x, y > -3.5*x - 13)
Which ordered pairs are solutions of the inequality?
Here we have the inequality:
7x + 2y > -26
The solutions of this are the pairs (x, y) that, when replaced on the inequality, make it true.
If we isolate y on the inequality we get:
7x + 2y > -26
2y > - 26 - 7x
y > (-26 - 7x)/2
y > -3.5*x - 13
Then the ordered pairs are of the form:
(x, y > -3.5*x - 13)
For example, suppose that we fix the value of x in 0, then:
y > -3.5*0 - 13
y > -13
So the points of the form (0, y > -13) are solutions.

A fitted linear regression equation is y = 6-2x. If × - 3 and the corresponding observed value of y = 2, the residual at this observation is:
The value of the residual is 2.
We are given a fitted linear regression equation. The equation is given below.
ŷ = 6 - 2x
The x-value for the data points is 3, and the corresponding y-value is 2. We have to find the value of the residual.
We will substitute the given values in the equation of the regression line.
ŷ = 6 - 2x
ŷ = 6 - 2(3)
ŷ = 6 - 6
ŷ = 0
Thus, the predicted value of y in the given regression equation is 0. The actual value of y is 2. The residual is the difference between the actual and predicted values of y. Let the residual be denoted by the variable "r".
r = y - ŷ
r = 2 - 0
r = 2
Hence, the residual is 2.
