5 0

so 3 tenths is 0.3 and 5 tenths is 0.5 but if you need to add them you would get 0.8

Daisy is building a rectangular pen for her chickens along one wall in her back yard. She needs to build a fence

frosja888 [35]

Answer:

Daisy has one side of the rectangular pen along the wall, so she needs one width, w, and two lengths, 2ℓ. She has at most 125 feet of fencing materials to build the fence for her pen

1 second/24 frames

so if he started with 0 frames

time s = (1/24) (additional f)

but he already had at least 250 frames

time s = (1/24)( f-250) or maybe less time if he had more than 250

24 s </= f - 250

f >/= 24 s + 250

The moon is a sphere with radius of 959 km. Determine an equation for the ellipse if the distance of the satellite from the surf

Sergeeva-Olga [200]

Answer:

$\frac{x^2}{1316^2}+\frac{y^2}{1669^2}=1$

Step-by-step explanation:

An ellipse is the locus of a point such that its distances from two fixed points, called foci, have a sum that is equal to a positive constant.

The equation of an ellipse with a center at the origin and the x axis as the minor axis is given by:

$\frac{x^2}{b^2}+\frac{y^2}{a^2} =1 \\\\where\ a>b$

Since the distance of the satellite from the surface of the moon varies from 357 km to 710 km, hence:

b = 357 km + 959 km = 1316 km

a = 710 km + 959 km = 1669 km

Therefore the equation of the ellipse is:

$\frac{x^2}{1316^2}+\frac{y^2}{1669^2}=1$

In the diagram, CD = 15 and CF = 39. If line DF is tangent to point C, then DF = ?

Neko [114]

I hope this helps you

DF^2+DC^2=FC^2

DF^2+15^2=39^2

DF^2=39^2-15^2

DF^2=24.54

DF=36
