The sunflower had a height of 13 inches on day 0 and 13.91 inches on day 1.
Because sunflowers are big feeders and require a slightly alkaline soil (pH 6.0 to 7.5), make sure we put them in nutrient-rich soil. Before planting, we should also make sure the soil is weed-free. Since a sunflower is cultivated in a garden, its height grows by 7% every day. The sunflower is 15.7 inches tall 2.79 days after being planted. To get the sunflower's 1-day growth factor, apply the following calculation:
X x (1 + 0.07) ^ 2.79 = 15.7
X x 1.07 ^ 2.79 = 15.7
1.2077X = 15.7
X = 15.7 / 1.2077
X = 13
13 x 1.07 = 13.91
The sunflower therefore measured 13 inches on day 0 and 13.91 inches on day 1.

The net worth of the dentist is $381,585. And the correct option is D.
What is net worth?A person's or company's net worth is the value of their assets less the amount of liabilities they have.
The personal assets and liabilities of a dentist are listed below.
Car Value = $26,250
Car Loan = $4,600
Savings Account Balance = $42,607
Office Equipment = $19,400

What are the coordinates of the point on the direct line segment from (-5, -10) to (2, 4) that partitions the segment into a ratio of 2 to 5?
Now the given coordinates are,
(-4,10) and (2,-10)
Thus, we have,
x₁ = -4
y₁ = 10
x₂ = 2
y₂ = -10
Given ratio, m₁ : m₂ = 1 : 3
⇒ m₁ = 1; m₂ = 3
Let (x,y) be the coordinates of the point on the directed line segment from (-4,10) to (2,-10) that partitions the segment into a ratio of 1 to 3.
Since the section formula is given as,
So, x = (m₁x₁ + m₂x₂) / (m₁ + m₂)
y = (m₁y₁ + m₂y₂) / (m₁ + m₂)
Put the values,
x = [1(-4) + 3*2)] / (1 + 3) = (-4+6) / 4 = 2/4
⇒ x = 1/2
Similarly y = [1(10) + 3*(-10)] / (1 + 3) = (10-30) / 4 = -20/4
⇒ y = -5
So, the required coordinates are (1/2, -5)
Thus, the coordinates of the point on the directed line segment that partitions the segment into a ratio of 1 to 3 is (1/2, -5).

Dorothy wants to purchase a car. She reviewed her budget and can comfortably afford a car payment of $490 per month. She has good credit and anticipated being able to secure a 4-year loan at 4% interest.What is the maximum cost she should pay for a car to stay within her budgeted monthly amount?
$21702.
$19762.
$16185.
$10386.
The maximum cost Dorothy should pay for the car to stay within her monthly budget amount is $23,518.84. See the explantion below.
What is a budget?A budget is a financial plan that takes into account both income and costs. In other words, it's a projection of how much money you'll make and expend over a specific time period, such as a month or a year.
The calculation that justified the above amount is solved as follows:
Given that:
Rate = 4%
Time = 4 years
The monthly payment is $490, to determine the amount (maximum) in 4 years, we use the Compound Interest formula:
A = P (1+ (r/n)ⁿᵇ
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
b = number of time periods elapsed
A = P (1 + (0.04/1)^(1x4)
A = P (1.04)⁴ in four years
Hence, given that the monthly payment over the four-year period is $490, we say:
P [(1.04)⁴] /12 x4 = 490
⇒ P (1.04)⁴ = 490 x 48
P = (490 x 48)/1.1699
P = 20104.2824173
P [tex]\approx[/tex] 20,104
The maximum amount payable hence
= 20,104 (1.04)⁴
A = 23518.837

There are nine different steps in questionnaire design process among which the first step is to decide upon the information required.
A good survey needs a well-designed questionnaire. However, as there is no theory of questionnaires to serve as a guide, the researcher must build his or her own intuition for what constitutes "excellent design."
A good questionnaire should directly contribute to the accomplishment of the study's goals, give complete and accurate data, be simple for interviewers and respondents to complete, allow for solid analysis and interpretation, and be brief.
The design of a questionnaire will depend on whether the researcher wants to gather quantitative data or qualitative data for the sake of better understanding or developing hypotheses about a subject (to test specific hypotheses that have previously been generated).
In the questionnaire design process, there are in all nine steps in developing the questionnaire -

What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
For example x ∝ y
The graph of seconds and ounces has shown.
If we look at the graph it is clear that as the ounces are increasing the seconds are also increasing. Therefore, it is a direct proportion.
Let's suppose the proportion is x ∝ y where x is ounces while y is seconds.
Removing proportionality,
x = ky
k = x/y
Substitute,(x,y) = (1,2)
k = 1/2
Hence "The proportionality is the direct relation of two variables thus the constant of proportionality of the given graph is 1/2".

My number is three different digits, the sum of the digits is equal to 3x5, the hundreds digit is the only odd digit, i'm greater than 30x9 and less than 50x9
Answer: 735
Step-by-step explanation:
Calculate the length of the sides marked x and y
Step-by-step explanation:
there is no side marked y.
to get x :
the graphic shows us already the split of the overall object into sub-shapes :
2 right-angled triangles
1 rectangle
x is the sum of the width of the rectangle and the shorter leg of the larger, top right-angled triangle.
to get both we need to use Pythagoras :
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs of the triangle.
let's start with the shorter leg of the larger triangle.
the Hypotenuse is 18, and the longer leg is the same as the length of the "underlying" rectangle : 10.
so, we get
18² = 10² + leg1²
324 = 100 + leg1²
leg1² = 224
leg1 = sqrt(224) = 14.96662955...
now to the width of the rectangle.
it is the same as the longer leg of the smaller triangle on the right side.
its Hypotenuse is 5. its shorter leg is 2.
so, we get
5² = 2² + leg2²
25 = 4 + leg2²
leg2² = 21
leg2 = width rectangle = sqrt(21) = 4.582575695...
x = leg1 + leg2 = 14.96662955... + 4.582575695... =
= 19.54920524...

The equations of the line will be expressed as y = 4 and y = -2x + 11 respectively.
Slope of a line may be defined as the steepness of a curve on graph. Slope is denoted by 'm'. If we are given two points (x₁, y₁) and (x₂, y₂) then the slope of line can be given by m = (y₂ - y₁)/(x₂ - x₁). Now, we have a line y = 6 and this line is parallel to x-axis, so the slope of this line is zero. Since, we have to find the equation of line parallel to given line so the slope of the line parallel to line y = 6 will also be equal to zero. Now, equation of line from points (3, 4) and slope zero is given by
(y - 4) = 0×(x - 3)
=> y - 4 = 0
=> y = 4 which is the required equation.
Now, for the second part we have need to find the equation of line parallel to line y = -2x - 1 and from point (4, 3). The slope of new line is -2 which will be same as the given line as they both are parallel. Now, equation of line will be
(y - 3) = -2(x - 4)
(y - 3) = -2x + 8
y = -2x + 8 + 3
=> y = -2x + 11 which is the required equation.

If the probability that an event will occur is changed as a result of the occurrence of a previous event, the events are said to be dependent events.
There, are two types of events- dependent and independent. Independent ones are those wherein the occurrence of one event has no effect on the probability of occurrence of another one. For example- you and your classmate passing a test are both independent events.
On the other hand, dependent events are those events that are affected by a change in any one of the events probability changing. For example- studying for a test and passing the test are both dependent events.
