The length of a rectangle is the sum of the width and one. The area direct angle 72 units. What’s the length, in units, of the r
insens350 [35]

Answer:

The length of the rectangle is of 9 units.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

Area of a rectangle:

A rectangle has width w and length l. The area is the multiplication of these measures, that is:

A = wl

The length of a rectangle is the sum of the width and one.

This means that l = w+1, or w = l - 1

The area direct angle 72 units. What’s the length, in units, of the rectangle

We want to find the length. So

wl = 72

(l-1)l = 72

l^2 - l - 72 = 0

Quadratic equation with a = 1, b = -1, c = -72. So

\bigtriangleup = (-1)^{2} - 4(1)(-72) = 289

l_{1} = \frac{-(-1) + \sqrt{289}}{2*(1)} = 9

l_{2} = \frac{-(-1) - \sqrt{289}}{2*(1)} = -8

Since the length is a positive measure, the length of the rectangle is of 9 units.

What is the measure of
harina [27]

Answer:

<DAB   = 120

Step-by-step explanation:

7)

<DAB = ?

<DAB + <DCB = 180

so

16x + 8 + 8x + 4 = 180

24x + 12 = 180

24x = 168

x = 7

<DAB  = 16(7) + 8 = 120

Anna [14]

Answer:

Step-by-step explanation:

The pediatrician said that the z-score for the boy's height, relative to other 2-year-olds in the country, was 1.59

He explains to the parents of the boy, that the extreme 5% of cases often require special attention.

(A) Does this child fall into that group?

Yes, this child falls into that group. He is among the extreme 5% of cases at the tail of the distribution.

(B) What do you need to assume about the heights of 2-year-olds, in order to find your answer to part (A)?

Assume that the distribution of heights is skewed, the heights are independent of one another, and the number of heights is very large.
