Answer:

Step-by-step explanation:

x-intercept: Set y = 0 and solve for x:

0 = mx + b, or mx = -b, or x = -b/m. x-intercept is then (-b/m, 0)

y-intercept: Set x = 0 and solve for y: y = m(0) + b, or y = b. y-intercept is then

(0, b).

Vaselesa [24]

Answer:

14.6°C

Step-by-step explanation:

Method 1

Higher value - lower value

12.2°C - (-2.4°C) *two negatives make a positive

12.2 + 2.4

14.6°C

Method 2

-2.4°C to 0°C = 2.4 increase (+2.4°C)

0°C to 12.2°C = 12.2 increase (+12.2°C)

Total change = 12.2 + 2.4= 14.6°C

cylinder:

V = πr²h

V = 3.14(2)² * 3

V = 3.14(4) * 3

V = 3.14(12)

V = 37.7m³

rectangular prism:

V = lwh

V = (2.4)(9)(5)

V = 108m³

the entirety of the sculpture:

V = volume of cylinder + volume of rectangular prism

V = 37.7 + 108

V = 145.7m³
