The sun's mass is about 30 million times greater than the moon. Why does the gravitational pull between earth and the moon affec
lakkis [162]
Even though the mass of the sun is much greater than the mass of the moon, the moon has a greater influence on the tides than the sun. This is because the sun is much farther away from the earth, so its tidal force is only about half that of the moon.

Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the arc length given that r
Komok [63]

Answer:

The required length is 37.68 cm

Step-by-step explanation:

We have given the radius of  which is 3 cm and  \thetawhich is \pi\cdot 4

We will use \pi=3.14

We know the formula for length of arc which is:

length of arc=radius x angle

We will substitute the values given we will get:

length=3(3.14)(4)

length=37.68

Hence, the required length is 37.68 cm

A cube-shaped hole is cut in a rectangular prism as shown below.
IgorC [24]
Surface area of the prism is 2xy+2xz+2yz 
I think, we can cut hole on the face of the prisma 40x30, and size of the whole will be 5X5X5
hole increases surface area. If side of the cube is "a", then a^2 is the area of the one face of the cube.  
when we are doing the hole, we remove 2 faces and add 4 more faces, so 
 2xy+2xz+2yz-2a^2+4a^2=  2xy+2xz+2yz+2a^2
So, 2*5*40+2*5*30+2*40*30+2*5^2=3150 cm^2
 i hope it helps, it is what i can come up with now

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)? f(x) = –3x – 6 f(x) = –3x – 4 f(x
vredina [299]

Answer:

f(x)=-3x+14

Step-by-step explanation:

we have

y+1=-3(x-5)

Isolate the variable y

Distributed right side

y+1=-3x+15

Subtract 1 both sides

y=-3x+15-1

Combine like terms

y=-3x+14

Convert to function notation

Let

f(x)=y

f(x)=-3x+14
