Answer:

3.56 cm.

Step-by-step explanation:

1/3 π r^2 h = V

1/3 π (5.13)^2 h  = 98

h = 98 / (1/3 π (5.13)^2)

=  98 / 27.55899

= 3.556.

5n + 34 = -2 ( 1 - 7n)<br>this is due by midnight.<br><br>NO LINKS PLEASE!
kodGreya [7K]

Answer :

n = 4

Step-by-step explanation:

5n + 34 = -2(1-7n)

first distribute

5n + 34 = -2(1) -2(-7n)

5n + 34 = -2+14n

-5n

+2

then get all of n to the same side

36 = 9n

isolate the variable

36/9 = 9n/9

4 = n

S , U , N are collinear. Select the point that satisfies the definition of betweenness if NU + US = NS .
Arturiano [62]
Given that the line segments NU and US can also be written as line segment NS then Point U would satisfy the Definition of Betweenness. 

This simply means that Point U lies between Points N and S along the same line.

Please help I will give out brainliest
Licemer1 [7]

Answer:

Step-by-step explanation:

Our function is : 3x²-3x-1

  • 3x²-3x+2=2
  • 3x²-3x-1+3=2
  • 3x²-3x-1= -1
  • the number that gives us -1 is 1 (from the graph)

so x is 1

  • 3x²-3x-1= x+1  ⇒3x²-4x-2 = 0
  • Δ(the dicriminant)= (-4)²-4*3*(-2)= 16+24 =40
  • two solution x and y
  • x= (4-√40)/6 and y= (4+√40)/6
  • x= -0.38 and y = 1.7
  • so the estimations are -0.38 and 1.7
