From the top of a building 42 feet high, the angle of depression to a car stopped on the ground it is 27°. What is the distance from the car to the base of the building?

Answers

Answer:

[tex]82.43\ \text{feet}[/tex]

Explanation:

Angle of depression = [tex]27^{\circ}[/tex]

b = Height of building = 42 feet

[tex]\theta=90-27=63^{\circ}[/tex]

p = Distance from the car to the base of the building

From the trigonometric identities we get

[tex]\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=42\tan63^{\circ}\\\Rightarrow p=82.43\ \text{feet}[/tex]

The distance from the car to the base of the building is [tex]82.43\ \text{feet}[/tex].

A skateboarder starts from rest and accelerates a distance of 485 m reaching a final velocity of 20.0 m/s. How long does it take?

Answers

Hello, first we have to look at this part; "The skater starts from rest", which means that the initial speed is zero meters per second.

Once we know that the initial velocity is zero, to calculate the time, we apply the following equation:

s = [(Vo + V) / 2] × t

Like Vi value, is zero meters per second, let's do a simplification in the equation:

s = (V / 2) × t

Data:

s = Distance = 485 m

V = Final velocity = 20 m/s

t = Time = ?

Let's replace the equation according our data:

485 m = (20 m/s / 2) × t

Divide the velocity:

485 m = 10 m/s × t

Product's divided:

485 m / 10 m/s = t

Resolve last operation:

t = 48.5 s

Result:

Takes 48.5 seconds to reach that speed.

background information of drought in eastern cape​

Answers

Much of the Eastern Cape province in South Africa has been experiencing a severe drought since 2015. This drought has had major socio-economic effects particularly on the large impoverished rural population as well as on some urban areas where supplied water services have broken down in several cases. The region is influenced by both midlatitude and tropical systems leading to a complex regional meteorology that hitherto has not been much studied compared to other parts of South Africa. Here, the ongoing drought is examined in the context of long-term trends and the interannual rainfall variability of the region. Although the region has experienced drought in all seasons since 2015, focus here is placed on the spring (September–November) which shows the most consistent and robust signal. On average, this season contributes between about 25–35% of the annual rainfall total. Based on CHIRPS data, it is found that this season shows a significant decreasing trend in both rainfall totals as well as the number of rainfall days (but not heavy rainfall days) for spring over most of the province since 1981. On interannual time scales, the results indicate that dry (wet) springs over the Eastern Cape are associated with a cyclonic (anticyclonic) anomaly southeast of South Africa as part of a shift in the zonal wavenumber 3 pattern in the midlatitudes. Over the landmass, a stronger (weaker) Botswana High is also apparent with increased (decreased) subsidence over and near the Eastern Cape which is less (more) favourable for cloud band development and hence reduced (enhanced) rainfall during dry (wet) springs. Analysis of mid-century (2040–2060) CMIP5 rainfall projections suggests that there may be a flattening of the annual cycle over the Eastern Cape with the winter becoming wetter and the summer drier. For the spring season of interest here, the multi-model projections also indicate drying but less pronounced than that projected for the summer.

analyse the impact that the increasing number of social grants may have on the unemployment rate ​

Answers

Answer:

The increasing number of social grants that are being awarded by the government are having a negative impact on the nation's unemployment rate. This is so, fundamentally, because although it is obvious that humanitarianly these social grants are positive for the lives of people in need, on the other hand it relaxes them and removes the imminent need to get a job. Therefore, they tend to slow down the employment of these people, making the decrease in the unemployment rate not so evident.

Social grants is one that has brought reduction in unemployment rate as people can now use money to set up business.

those people who lived under mountain what does that mean for them?

Answers

Hill people, also referred to as mountain people, is a general term for people who live in the hills and mountains. This includes all rugged land above 300 metres (980 ft) and all land (including plateaus) above 2,500 metres (8,200 ft) elevation. The climate is generally harsh, with steep temperature drops between day and night. High winds, runoff from melting snow and rain cause high levels of erosion and thin, immature soils. Climate change is likely to place considerable stress on the mountain environment and the people who live there.

People have used or lived in the mountains for thousands of years, first as hunter-gatherers and later as farmers and pastoralists. The isolated communities are often culturally and linguistically diverse. Today about 720 million people, or 12% of the world's population, live in mountain regions, many of them economically and politically marginalized. The mountain residents have adapted to the conditions, but in the developing world they often suffer from food insecurity and poor health. They depend on crops, livestock and forest products, and tend to be poor. In the developed world the mountain people are generally prosperous, and the mountains may be used for tourism and outdoor recreation. Mining is also widespread and dates back to the pre-Christian era.

In parts of the developing world the mountain communities depend on remittances from young men who have gone to work in the lowlands or overseas. Although 70% of mountain people live in rural areas, the rest live in cities, including large cities such as Mexico City, with a population of around 21 million. The cities attract temporary or permanent migrants from the rural areas. The smaller cities are more connected to the mountain culture and economy than the larger ones.
