During a solar eclipse, what is causing the earth’s view of the sun to be darkened?

2 answers:

8 0

A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface.

If g is an increasing function such that g(2)=8 and g'(2)=5 calculate (g^-1)'(8)

9966 [12]

The inverse of a function is the reflection of it across the line y=x. If (2, 8) is on the graph of g(x), then (8, 2) is on the graph of its inverse. If the slope of g(2) is 5, then the slope of (g^-1)(8) is 1/5, the reciprocal of g'(2).

... (g^-1)(8) = 1/5

For the triangle shown below, complete the following table.

dem82 [27]

Answer:

Step-by-step explanation:

In the given triangle

With reference angle A

perpendicular (P) = 3

hypotenuse (h) = 5

So sin A = p/h = 3/5

and

With reference angle C

perpendicular (p)= 4

hypotenuse (h) = 5

Sin C = p/h = 4/5

hope it helps :)

Which equation is rewritten in vertex form

ser-zykov [4K]

Answer:

Option (2)

Step-by-step explanation:

Given expression is, y = (x + 3)² + (x + 4)²

By solving this expression,

y = x² + 6x + 9 + x² + 8x + 16

y = 2x² + 14x + 25

y = (2x² + 14x) + 25

y = 2(x² + 7x) + 25

y = 2[x² + 2(3.5x) + (3.5)² - (3.5)²] + 25

y = 2[x² + 2(3.5x) + (3.5)²] - 2(3.5)² + 25

y = 2(x + 3.5)² - 24.5 + 25

y = 2(x + 3.5)² + 0.5

$y=(x+\frac{7}{2})^2+\frac{1}{2}$

Therefore, Option (2) will be the vertex form.
