Answer:
B)
Step-by-step explanation:
1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.
2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: , where a = height, b = base, and c= hypotenuse.
(Simplify both sides of the equation)
(Subtract 4 from both sides)
(Take square root of both sides
3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.
Answer:
Options (E) and (G).
Step-by-step explanation:
From the data given in the table,
There is a common difference of $100 in every successive term of the amount of money.
Therefore, graph of the given table will represents a linear graph.
There are two points (5, 1200) and (6, 1300) lying on the graph.
Let the equation of the line is,
If A = Amount of money
n = Number of months
where 'n' = slope of the line
Slope =
=
= 100
Equation of the line passing through (6, 1300) and slope = 100
A - 1200 = 100(m - 5)
A = 100(m - 5) + 1200
A = 100m - 500 + 1200
A = 100m + 700
Therefore, Options (E) and (G) are the correct options.
