Which parabola will have one real solution with the line y = x - 5?

Answer:

y=x^2+7x+4

Step-by-step explanation:

because the sign before x^2 is positive, the graph would concave up, if there's only one intercept, it has to be the vertex. the vertex is the critical point.

solve every make the derivative of each function equals zero, you get the x where the vertex shall be, then get this"x" into y=x-5 see if the y in y=x-5 is equal to y=x^2+6x+9 or other options.

let me give u an example.

for y=x^2+x-4, the critical point shall be 2x+1=0,x=-1/2, and the y is -4.25,

if you plug x=-1/2 into y=x-5, it's -5.5, -5.5 doesn't equal to -4.25

Use the pattern to answer the question. 27, 18, 12, 8. Which expression can be used to find the nth term of the pattern?
xeze [42]

If you cross check with the answer , you’ll find option C to be the most appropriate option.

The difference between the first two terms is 9 and 9 is not a multiple of six, therefore first two are wrong.

Similarly, if you check option D for the first two terms , you get the second term as 27 which is false.

Therefore option C is the answer, also , it satisfies the series.

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has
pickupchik [31]

Answer:

If you draw this out, you can see that total fence equation will be:

2L + 4W = 1200

Simplify, divide by 2

L + 2W = 600

L = (600-2W)

:

Area;

A = L*W

Substitute (600-2W) for L:

A = (600-2W)*W

A = -2W^2 + 600W; a quadratic equation

 

:

The dimension that will produce the greatest area will be the "axis of symmetry

which is: x = %28-b%29%2F%282a%29

:

In this equation a=-2, b=600

W = %28-600%29%2F%282%2A-2%29

W = %28-600%29%2F%28-4%29

W = +150 ft is the width

:

Find the length

L = 600 - 2(150)

L = 300 ft is the length

:

We can say the a field 300 by 150 gives he greatest area

:

This illustrated on a graph where y axis is the area and x axis is the width:
