Mosquito = 2.5 x 10⁻⁶

Housefly = 2 x 10⁻⁵

Let's find their ratio: Mosquito/Housefly = (2.5x10⁻⁶)/(2 x 10⁻⁵)

M/H =(2.5/2) x (10⁻⁶/10⁻⁵)
M/H = (5/4) x (10⁽⁻⁶⁺⁵⁾
M/H  = (5/4) x 10⁻¹
M/H = (5/4) x (1/10)
M/H = 5/40
M/H = 1/8 OR 8 M  = 1 H , SO the housefly is 8 times the weight of the mosquito

Answer:

Step-by-step explanation:

The slope of the line in question is the same as the slope of the line parallel to it. Using y = mx + b, where m is the slope, we find the slope of our line is -3.

Using the pt-slope form, y - y1 = m( x - x1), we get y - (-1) = -3( x - 2) or y + 1 = -3x + 6. Which leads us to y = -3x + 5. QED

What is the length of the major axis of the conic section shown below?
sveticcg [70]

\dfrac{(x-2)^2}{49}+\dfrac{(y+5)^2}{36}=1

The equation of a elipse:

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1

The length of the major axis is equal 2a if a > b or 2b if b > a.

We have

a^2=49\to a=\sqrt{49}=7\\\\b^2=36\to b=\sqrt{36}=6\\\\a > b

therefore the length of the major axis is equal 2 · 7 = 14.
