Your two equations for this question would be:

n + d = 234
5n +10d = 16.10

So with that you must take your two equations and make them equal to eachother.

Hope this helped :)

Jerry climbed 210 feet in elevation. he want down 300 feet. what integer represents his toal changes in elevation.
babymother [125]

For every action you want to record the "Distance", you do not want to find the displacement. 210 feet + 300 feet = 510 feet. His total distance traveled is 510 feet

Displacement however would be -90 = 210 - 300 because he is now -90 feet from where he begun. The reason the 90 is negative is because he is lower now than he was before because the downward movement was greater than the upward movement.

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?
zhuklara [117]

Answer:

f(-2) = 0

Step-by-step explanation:

Given that:

f(x) = bx^2 + 32

f(2) = b(2)^2 + 32

f(2) = 4b + 32

f(2) = 4b = -32

f(2) = b = -32/4

f(2) = b = -8

Thus;

f(-2) = -8(-2)^2 + 32

f(-2) = -8(4) + 32

f(-2) = -32 + 32

f(-2) = 0

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.
