Delilah is making a garden that she wants to be 5 feet longer than it is wide. Write
the equation that Delilah should use to determine the width of a garden that has an
area of 50 square feet.
How wide and how long does Delilah need to make her garden to achieve the desired speciation?
Width =
The equation is 50 = (5 + w)w and the width is 5 and the length is 10
Write the equation that Delilah should use to determine the width of a garden that has an area of 50 square feet.The given parameters are
Area = 50
Length = 5 + Width
This means that
l = 5 + w
The area is calculated as
A = lw
Substitute l = 5 + w in A = lw
A = (5 + w)w
Substitute A = 50 in A = (5 + w)w
50 = (5 + w)w
Hence, the equation is 50 = (5 + w)w
How wide and how long does Delilah need to make her garden to achieve the desired speciation?We have
50 = (5 + w)w
Express 50 as 10 * 5
So, we have
10 * 5 = (5 + w)w
This means that
5 + w = 10
w = 5
Solve 5 + w = 10
w = 5
Substitute w = 5 in l = 5 + w
l = 5 + 5
l = 10
Hence, the width is 5 and the length is 10

Calculate and interpret the residual for the flower that had 2 tablespoons of sugar and looked fresh for 204 hours.
The Residual is -8.4 hours and the interpretation of the given residual is that the carnation stayed fresh for 8.4 hours less than expected based on how much sugar it received.
How to find the residual of a scatter plot?A residual plot is a type of scatter plot where the horizontal axis represents the independent variable, or input variable of the data, and the vertical axis represents the residual values.
Now, looking at the given residual plot and using a calculator online, we can say that the equation of the least squares regression line is;
y^ = 180.8 + 15.2x
Now, for 2 tablespoons of sugar , we have x = 2. Thus;
y^ = 180.8 + 15.2(2)
y^ = 212.4 hours
Residual for 204 hours is;
Residual = 204 - 212.4 = -8.4 hours

If the temperature on the ground is 63F, then the air temperature x miles high is given by T=63−29x. Determine the altitudes at which the air temperature is less than 4.4F.
The temperature is less that 4.4 °F for altitudes greater than 2.021 miles high.
In which altitudes do we get a certain range of temperatures?
Herein we find that the temperature, in grades Fahrenheit, decreases linearly inasmuch as the altitude, in miles, increases. In accordance with the statement, we solve for T in the following inequality:
63 - 29 · x < 4.4
63 - 4.4 < 29 · x
58.6 < 29 · x
29 · x > 58.6

the 3rd term of a linear sequence is 17. the 45th term is 269. determine the formula for the nth term.
Step-by-step explanation:
a linear or arithmetic sequence has a start value as first term, and then every following term is created by adding the same constant to the previous term.
a1 = a
a2 = a1 + c = a + c
a3 = a2 + c = a + c + c = a + 2c
a4 = a3 + c = a + c + c + c = a + 3c
...
as we can easily see
an = an-1 + c = a + (n-1)c
in our case
a3 = 17 = a + 2c
a = 17 - 2c
a45 = 269 = a + 44c = 17 - 2c + 44c = 17 + 42c
252 = 42c
c = 6
a = 17 - 2c = 17 - 2×6 = 17 - 12 = 5
so,
an = 5 + (n-1)×6

The profit, in dollars, a company makes selling a new line of iPhones is given by the
equation P(x) = −0.03x^2 + 225x − 24000, where x is the number of iPhones sold.
a) Find the instantaneous rate of change of the profit at x = 1000 iPhones sold.
b) Interpret your result.
The instantaneous rate of change is the change in the concentration of rate that occurs at a particular point of time. The variation in the derivative values at a particular point denotes the instantaneous rate of change. The instantaneous rate of change at a point is the value of derivative function evaluated at that point.
P(x) = −0.03x^2 + 225x − 24000
To find the instantaneous rate of change we need to differentiate the equation with respect to x
P'(x) = -0.06x +225
at x =0
P'(0)= 225
now put x = 1000 because we need to know instantaneous rate of change of the profit at x = 1000 iPhones sold
P'(1000) = -0.06(1000) + 225
= -60 + 225
= 165
Hence, the instantaneous rate of change of the profit at x = 1000 iPhones sold is 165
This means that the increase in sales also increase the profit but at a decreasing rate or the marginal profit of iPhones increases with decreasing rates

simplify 4/x+4 + x/x-4
A.Hint: Find the common denominator and then add.
The simplification of the given equation is (x² + 8x - 16)/(x-4)(x+4) by the method of LCM.
What is defined as the LCM?LCM is an abbreviation for least common multiple. The smallest number which is a multiple of both numbers is the least common multiple of them.For, the given equation;
4/(x+4) + (x/x-4)
To find the common denominator, use LCM; multiply a first term by (x-4)/(x-4) and the 2nd term by (x+4)/(x+4):
= (x-4)×4/(x-4)(x+4) + x×(x+4)/(x-4)(x+4)
The following step is to disperse the 4 (x-4) and x (x+4);
So you now have;
= (4x-16 + x² + 4x)/(x-4)(x+4)
Further simplify.
= (x² + 8x - 16)/(x-4)(x+4)
As, (x² + 8x - 16) is further not factor-able. So, the simplified form of the given equation is; (x² + 8x - 16)/(x-4)(x+4).

The midpoint of AB is M(0, -3)M(0,−3). If the coordinates of AA are (6, -5)(6,−5), what are the coordinates of BB?
Step-by-step explanation:
Mid point of AB is (0, -3)
Coordinate of A is (6, -5)
By using mid point formula, if P(x, y) and Q (x′, y′), then mid point of P= (x + x′)/2 , (y + y′)/2
So, ( 0, -3)= 6+x/2, -5+y/2
0=6+x/2
0=6+x, x = -6
and, -3= -5+y/2, -6= -5+y....
y = -1
so the coordinate is (-6, -1)
To find the midpoint of two points, we can use the following formula:
[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two endpointsSolving the QuestionWe're given:
