Answer:

It will take 10^3 days for the comet to reach earth.

Step-by-step explanation:

10^8 = 100,000,000

10^5 = 100,000

100,000,000/100,000 = 1,000

1,000 is equal to 10^3

makkiz [27]

Answer:

-2, -1

Step-by-step explanation:

the x same cause if you reflect across the x-axis so you move on the y-axis. and reflect means the same distance from the point you reflect (that it was 1 cause it was 1 point above the x-axis) just negative so -1 now. if the original point was -2,-1 so the answer was -2,1.

A satellite dish is shaped like a paraboloid of revolution. The signals that emanate from a satellite strike the surface of the
antiseptic1488 [7]

Answer:

c = 9 feet

Step-by-step explanation:

In this situation, one is to find the 'c' : that is, the distance between the vertex and the focus.

Given that, the equation for a vertical parabola:

y = (1/4c)(x-h)^2 + k

Supposing we place our parabola at the center, our equation becomes:

y = (1/4c)x^2

.

The problem gives us a point on the parabola: (12,4)

Then insert it in and solve for 'c':

y = (1/4c)x^2

4 = (1/4c)12^2

4 = (1/4c)144

4 = (1/c)36

4c = 36

c = 36/4

c = 9 feet

Vilka [71]

Check the picture below.

let's firstly convert the mixed fractions to improper fractions and then subtract.

\stackrel{mixed}{42\frac{1}{2}}\implies \cfrac{42\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{85}{2}} ~\hfill \stackrel{mixed}{67\frac{3}{7}}\implies \cfrac{67\cdot 7+3}{7}\implies \stackrel{improper}{\cfrac{472}{7}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{472}{7}~~ - ~~\cfrac{85}{2}\implies \cfrac{(2)472~~ - ~~(7)85}{\underset{\textit{using this LCD}}{14}}\implies \cfrac{944~~ - ~~595}{14}\implies \cfrac{349}{14}\implies 24\frac{13}{14}

One of the sides of a parallelogram is 4.2 cm and the altitude to that side is 3.6 cm. Find the perimeter of the parallelogram i
adelina 88 [10]
The product of side length and altitude is area. The area remains the same regardless of how you measure it.

From the first side and altitude,
.. area = side*altitude = (4.2 cm)*(3.6 cm) = 15.12 cm^2
From the second side and altitude
.. area = side*altitude
.. 15.12 cm^2 = side*(2.4 cm)
.. side = (15.12 cm^2)/(2.4 cm) = 6.3 cm

The perimeter is the sum of the measures of all sides. Opposite sides are of equal measure.
.. perimeter = 2*(4.2 cm +6.3 cm) = 21.0 cm
