Step-by-step explanation:

Using the vertex of the quadratic equation, it is found that the company should assign 5 programmers in order to complete the development as quickly as possible.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The vertex is given by:

[tex](x_v, y_v)[/tex]

In which:

[tex]x_v = -\frac{b}{2a}[/tex]

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]

Considering the coefficient a, we have that:

In this problem, the time needed for x programmers to finish the project is given by:

T(x) = 100 - 30x + 3x².

Which means that the coefficients are a = 3, b = -30, c = 100. The number of programmers which will minimize the time is given by:

[tex]x_v = -\frac{-30}{6} = 5[/tex]

Answer:

Step-by-step explanation:

Part A

Area of a rectangle = length x width

Garden area = 7 3/4 x 2 2/3

= 31/4 x 8/3

= 62/3

= 20 2/3 square feet

Part B

5/8 of the area = 62/3 * 5/8

= 31*5 / 3*12

= 155 / 36

= 4 11/36

The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.

Answer:it is 50 because you have to subtract the area of the triangle (14) from the area of the square (64)!

Answer:

[tex]\displaystyle \perp\:y = -\frac{4}{7}x + 6\frac{4}{7} \\ \parallel\:y = 1\frac{3}{4}x - 12[/tex]

Step-by-step explanation:

Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 1¾ becomes −⁴⁄₇, and we move forward:

[tex]\displaystyle 2 = -\frac{4}{7}[8] + b \hookrightarrow 2 = -4\frac{4}{7} + b; 6\frac{4}{7} = b \\ \\ \boxed{y = -\frac{4}{7}x + 6\frac{4}{7}}[/tex]

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so 1¾ remains as is as we proceed:

[tex]\displaystyle 2 = 1\frac{3}{4}[8] + b \hookrightarrow 2 = 14 + b; -12 = b \\ \\ \boxed{y = 1\frac{3}{4}x - 12}[/tex]

I am joyous to assist you at any time.

[tex] \sf \: b - 7400 = {2}^{t} [/tex]

We have to make it as a function of T

So,

[tex] \sf \: b(t) = {2}^{t} + 7400[/tex]

We moved the constant to the right-hand side and changed its sign...

Step-by-step explanation:

The membership would be worth the money if the number of DVD's rented is more than 20

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the cost of renting x DVD

They decided to create a membership for $20 flat fee and then charge $4 per DVD for members. For members:

y = 4x + 20

Non-members could also rent a DVD, but for $5 per DVD

y = 5x

The membership would be worth the money if:

5x > 4x + 20

x > 20

The membership would be worth the money if the number of DVD's rented is more than 20

Answer:

i think it would be -14 + 2y so the mistake was making the 2y negative

Step-by-step explanation:

Negative times negative = positive

Answer: The distribution of -2(7 - y) is incorrect. They came out with -14 -2y.

It should have been -14 + 2y

At the end, it would have been a division by +2 , so the solution would be y=3

Answer:

Slope = -1/2.

Step-by-step explanation:

2 points on the line are (10, 0) which is where the line passes through the x-axis and (0, 5 ) where it passes through the y-axis.

The slope = (difference in y coordinates) / ( corresponding difference in  x coordinates)

= (5 - 0) / (0 - 10)

= -5/10

= -1/2.
