Answer:
(a) check the explanation
(b) the possible values of b is 6i or -29
Explanation:
Given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
(a)
factor of the given function = 2x + b
then, 2x + b = 0
x = -b/2
substitute the value of b into the given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
[tex]16(\frac{-b}{2} )^4 -4(\frac{-b}{2})^3-4b^2(\frac{-b}{2})^2 +7b(\frac{-b}{2})+18=0\\\\b^4+\frac{b^3}{2} -b^4-\frac{7b^2}{2} +18=0\\\\\frac{b^3}{2} -\frac{7b^2}{2} +18=0\\\\multiply\ through \ by \ "2"\\\\b^3-7b^2+36 =0 \ (shown)[/tex]
(b)
b³ - 7b² + 36 = 0
b²(b - 7) + 36 = 0
b²(b - 7) = -36
b² = -36 or b - 7 = -36
b = √(-36) or b = -36 + 7
b = √(-1) x √(36) or b = -29
b = 6i or -29
The process of nomadic hunter gatherers becoming sedentary farmers.
Answer:
It took climate change, fertile river valleys, domestication of crops and animals so that the hunter-gatherers became sedentary farmers.
Explanation:
Initially, all humans were hunter-gatherers. This was due to multiple reasons, with one the biggest one probably being the climate which was not enabling good conditions for the hunter-gatherers to transform their lifestyle. All other conditions needed were stopped because of the climate conditions, so humans had to do what they could to survive in those conditions.
About 10 years ago though the bad climate conditions ended, or rather the Ice Age ended. This resulted in a much warmer climate, which in turn created much more water bodies like rivers and lakes, much more vegetation, and they contributed to the creation of much more fertile soil.
With these conditions in place, the humans quickly saw that there is huge potential in some plants and animals, so they started to farm them, select the ones with the best characteristics, and gradually producing enough food for themselves. With the food problem solved, humans didn't have the need to wonder around all the time, so they started abandoning the hunter-gatherer lifestyle and started settling in one place.

Why is aq. Na2CO, basic?
Answer:
Basicity is due to the increase in OH− ions. So, the more Na+ is hydrolysed more OH− are produced, hence aqueous solution of Na2CO3 is basic in nature.

A. Pilots use this projection type.
B. The equator usually serves as the central point.
C. Latitude lines connect at a central point.
D. Conic projections are the most distorted type.
Answer:
the anser is A Pilots use this projection type.
Explanation:
hehe
The statement that can be considered as a feature of a conic projection as regards this question is :A. Pilots use this projection type.
Conic projection can be regarded as map projection whereby there is a projection of an area of the earth on to a cone, and in this case the vertex is been placed above one of the poles.Conic projection are been utilized in mid-latitude zones having an (east–west) orientation. It is been used by a pilot.
Therefore, option A is correct.

The wind around a surface low pressure in the Northern Hemisphere blows __. a. counterclockwise perpendicular to isobars.b. clockwise perpendicular to isotherms.
Answer:
a. counterclockwise perpendicular to isobars
Explanation:
Due to the Coriolis force that shifts the air in such a way that it follows the pressure contours thereby making the air or wind blow in a counter-clockwise direction in the Northern Hemisphere around low pressure and move out around high pressure in a clockwise direction.
Hence, it can be concluded that The wind around a surface with low pressure in the Northern Hemisphere blows "counterclockwise perpendicular to isobars."

Solve for the value of p.
|(3p+1)°
(p+7)
Answer:
P=43
Explanation:
As, the both angles are linear, so if we add them, we will get 180°.
So, p+7 + 3p+1 = 4p + 8
So, 4p + 8 = 180
So, 4p = 180 - 8
4p = 172
P= 172/4
P = 43
So p+7 + 3p+7 = 43 + 7 + ( 3x43 + 1) = 180
Therefore, p = 43
Find the measure of the missing angles.

1. A 15 minute quadrangle map of a region within the United States with a longitude of 76'00'00" in the right corner of the map, will read what longitude in the left corner? Refer to your lab instructions. 2. A 15 minute quadrangle map of a region within the United States with a latitude of 43 15'00" in the top corner of the map, will read what latitude in the bottom corner? 3. A fractional scale of 1:24,000 means that 1 inch-feet. 4. A fractional scale of 1:24,000 means that 1 footkilometers.
Answer:
Following are the solution to the given points:
Explanation:
15-minute charts display a latitude and longitude zone of 15 minutes. It was a collection of graphs designed to chart the whole US area on the very same scale.
In point 1:
In the United States, the American Government raises the worth through North to South (from the right of the map towards the left).
Therefore, the left portion's latitude value: =76°00’00”+0°15’00”=76°15’00”
In point 2:
That value of altitude increases to the top of the map.
That latitude meaning at bottom of a map:
=43°15’00” - 0°15’00”=43°00’00”
In point 3:
In this floor as per the scale from 1 inch mostly on map.
Thus 1"=24000"=2000 ft
In point 4:
The map depicts 24000 ft at the floor in conjunction with the scale 1 foot. Consequently, 1 foot=24000ft=7,3152 km

Which of the following accounts for why some American manufacturing companies have located factories in Mexico?
Abundant capital resources,
A supply of inexpensive labor
Favorable climate conditions,
Political stability in the region
The correct answer is B. A supply of inexpensive labor
Explanation:
Manufacturing most products in Mexico is cheaper than doing this in the U.S. The main reason for this is that in Mexico labor (workers needed for production) is cheaper than in the U.S. This factor is related to the fact the currency in Mexico has less value than the currency in the U.S. and the social, economic, cultural conditions are different. Besides this, production can be easily controlled in Mexico because this borders the U.S. According to this, one factor that makes some American companies locate factories in Mexico is the supply of inexpensive labor.
