Step-by-step explanation:

if x is equal to - 1

Then

2x² + 5x + 6

= 2* ( -1)² + 5 * (- 1) + 6

= 2 - 5 + 6

= 8 - 5

A stock has had returns of 7 percent, 25 percent, 17 percent, −13 percent, 25 percent, and −6 percent over the last six years. W
Tems11 [23]

Answer: Geometric average return would be 0.10% and arithmetic average return would be 9.17%.

Step-by-step explanation:

Since we have given that

Returns are as follows:

7%, 25%, 175, -13%, 25% and -6%.

Geometric return is given by

\sqrt[6]{(1+0.07)(1+0.25)(1+0.17)(1-0.13)(1+0.25)(1-0.06)}-1\\\\=\sqrt[6]{(1.17)(1.25)(1.17)(0.87)(1.25)(0.94)}-1\\\\=0.097\%=0.10\%

Arithmetic average return would be

\dfrac{7+25+17-13+25-6}{6}=9.17\%

Hence, geometric average return would be 0.10% and arithmetic average return would be 9.17%.

If the parallelogram floor needs a base of 16 feet,what will the height of the floor be
nydimaria [60]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete because the area of the parallelogram is missing. However, the following will guide you in answering the question</em>

Given

Base = 16\ ft

Required

Determine the Height

Area of a Parallelogram is:

Area = Base * Height

Make Height the subject

Height = \frac{Area}{Base}

Substitute 16 for Base

Height = \frac{Area}{16}

This implies that you divide the value of area by 16 to get the height of the parallelogram.

Take for instance;

Area = 64ft\²

The height would be

Height = \frac{64}{16}

Height = 4\ ft

Or

Area = 80ft\²

The height would be

Height = \frac{80}{16}

Height = 5\ ft
