It's urgent please help! find the perimeter of the triangle with vertices listed (-5,2), (3,2), (1,6)
Answer:
19.68
Explanation:
Given:
Vertices : (-5,2), (3,2), (1,6)
To get the length of each side, we need to
Length = √(x2 - x1)^2 + (y2 - y1)^2
calculate the distance between the points ;
Taking, (-5,2), (3,2)
L1 = √(3 -(-5))^2+ (2 -2)^2
L1 =√(3 + 5)^2 + 0^2
L1 = √8^2 = √64 = 8
Taking L2 ; (3,2), (1,6)
L2 = √(1 -3)^2 + (6 - 2)^2
L2 = √ (-2)^2 + 4^2
L2 = √ 4 + 16
L2 = √20 = 4.47
Taking L3 ; (-5,2), (1,6)
L3 = √(1 - (-5))^2 + (6 - 2)^2
L3 = √(1 + 5)^2 + (6 - 2)^2
L3 = √6^2 + 4^2
L3 = √36 + 16 = √52
L3 = 7.21
Therefore, perimeter = L1 + L2 + L3
8 + 4.47 + 7.21 = 19.68
Which statement regarding vessel maintenance is true
Answer:
When removing oxidation (white powder spots) on vessel, use a non-phosphate detergent
Explanation:
Vessel maintenance is usually important to prevent any form of rusting as the vessels are made with metals which produce brown Iron oxide when exposed to moist air which are conditions of the water bodies.
It should be noted that when removing oxidation (white powder spots) on vessel, use a non-phosphate detergent. This form of detergent is usually very efficient and harmless to the organisms in the water bodies.
What are index fossiles and how can they be used to correlate rock layers found large distances apart?
Answer:
Ammonites, trilobites, and graptolites are often used as index fossils. Microfossils, which are fossils of microscopic organisms, are also useful index fossils.
Explanation:
Which of the following is true about how education and fertility rates are
generally globally related?
Check all that apply
A. More education generally means more children per family
B. Less education means less opportunity, and thus fewer children
C. Educated women are more likely to pursue business
opportunities
D. Educated women tend to have fewer children
Education and reproductive rates have a negative relationship. Generally speaking, educated women have fewer children than uneducated women. Thus, option D is correct.
What is the fertility rate?The number of live births to women of a certain age throughout the year expressed as a percentage of the average yearly population of women of that age is known as the fertility rate at that age.
The fertility rate and education have a negative relationship. Women with more education tend to have fewer children than those without education.
Economic development can be seen as both a cause and a result of lower fertility rates: Positive effects of increased education on women's fertility are passed on to future generations due to lower fertility.
