A rectangular shelf with an area equal to x^2-16x+60 square units could have which possible dimensions for length and width

kenny6666 [7]

Answer:

Step-by-step explanation:

x²-16x+60

=x²-6x-10x+60

=x(x-6)-10(x-6)

=(x-6)(x-10)

so dimensions are x-6 and x-10.

Answer:

y - 3 = (1/2)(x - 4)

Step-by-step explanation:

The graph is hard to read, but we can make assumptions about the x- and y-values shown. The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3). Let's try finding the equation of the line using this assumed data:

The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.

We need the slope of the line. Recall that m = rise/run. Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2. Thus, the slope is m = rise/run = 2/4, or 1/2.

Substituting the known values into the point-slope equation y - k = m(x - h), we get:

y - 3 = (1/2)(x - 4)

Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (-5, -2) and point (8, -3) rounded

Dennis_Churaev [7]

Option D: 13 units is the distance between the two points

Explanation:

Given that the points are $(-5,-2)$ and $(8,-3)$

We need to find the distance between the two points.

The distance between the two points can be determined using the distance formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let us substitute the points $(-5,-2)$ and $(8,-3)$ in the above formula, we get,

$d=\sqrt{(8-(-5))^2+(-3-(-2))^2}$

Simplifying the terms within the bracket, we have,

$d=\sqrt{(8+5)^2+(-3+2)^2}$

Adding the terms within the bracket, we get,

$d=\sqrt{(13)^2+(-1)^2}$

Squaring the terms, we have,

$d=\sqrt{169+1}$

Adding, we get,

$d=\sqrt{170}$

Simplifying, we have,

$d=13.04$

Rounding off to the nearest tenth, we get,

$d=13.0 \ units$

Hence, the distance between the two points is 13 units.

Therefore, Option D is the correct answer.

What is the area of this trapezoid?

slamgirl [31]

Area of rectangle in the middle = 12 * 9 = 108
Area of left triangle = .5 * 2 * 9 = 9
Area of right side triangle = .5 * 5 * 9 = 22.5

Total area = 108 + 9 + 22.5 = 139.5 square inches
