Create an inequality:

17+2x>25

(x is the number of goldfish he bought)

Simplify:

2x>8

x>4

Graph is by making a point on the line at 4 with an open circle and include the numbers larger than it (to the right of 4 on the line)

Keep doing 4 over 1000 until the four reaches the 1000. If four does not go into 1000, then reduce the fraction 4/1000.

Which points are exactly 10 units from the point (–8, –2)? Check ALL that apply.

Archy [21]

Answer:

The points that are exactly 10 units from the point (–8, –2) are (2, –2) and (–8, 8).

Step-by-step explanation:

The distance formula is;

d= $\sqrt{( x_{2}-x_{1} )^{2}-(y_{2} -y_{1} )^{2} }$

So for distance between: (–8, –2) and (2, –2) is:

d= $\sqrt{( 2-(-8))^{2}-(-2 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Similarly for distance between: (–8, –2) and (–8, 8) is,

d= $\sqrt{( -8-(-8))^{2}-(8 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

A spherical exercise ball has a maximum diameter of 30 inches when filled with air. The ball was completely empty at the start,

Alex73 [517]

Answer:

A) A(t) = 4500*π - 1600*t

B) A(4) = 7730 in³

C) t = 8,8 sec

Step-by-step explanation:

The volume of the sphere is:

d max = 30 r max = 15 in

V(s) = (4/3)*π*r³ V(s) = (4/3)*π* (15)³

V(s) = 4500*π

A) Amount of air needed to fill the ball A(t)

A(t) = Total max. volume of the sphere - rate of flux of air * time

A(t) = 4500*π - 1600*t in³

B) After 4 minutes

A(4) = 4500*π - 6400

A(4) = 14130 - 6400

A(4) = 7730 in³

C) A(t) = 4500*π - 1600*t

when A(t) = 0 the ball got its maximum volume then:

4500*π - 1600*t = 0

t = 14130/1600

t = 8,8 sec
