Positionx (m)
9966 [12]

Answer:

A. 3.0 m/s

Step-by-step explanation:

Based on the graph,

velocity = Area of the graph

v =  \frac{y1 - y2}{x1 - x2}

(y : position and x : time)

Let y1 = 2m and y2 = 14m,

t1 = 0s and t2 = 4s

v = (14 - 2)m/(4-0)s

= 12m/4s

= 3.0 m/s

Let n = the number. A number exceeds 45 inequality
blondinia [14]
  This translates to "a number" is greater than 45. All you have to do now is translate these words into an algebraic statement. Basically, you replace "a number" with the variable which it is defined for, and you use the "greater than" symbol to show that the variable is greater than the value of 45.

Answer:

.85

Step-by-step explanation:

Compound interest formula

PV(1+\frac{i}{n})^{nt}

Melanie:

3800(1+\frac{.02}{4})^{(6*4)\\}\\=3800(1+.005)^{24}\\3800*1.1272=4283.21

Sebastian:

3800(1+\frac{.02}{12})^{12*6}\\3800(1.0017)^{72}\\3800*1.1274=4284.06

4824.06-4283.21= .85

an air conditioner can cool a room that has a volume of up to 3,600 cubic feet. a room shaped like a rectangular prism is 15 fee
valentinak56 [21]

The length of the air conditioner is 24 feet.

Volume = 3600 feet ³

Width = 15 feet

Height = 10 feet

Length = Unknown

Therefore, the value of the length will be calculated thus:

Volume = Length × Width × Height

3600 = Length × 15 × 10

Length = 3600 / (15 × 10)

Length = 3600 / 150

Length = 24

The length is 24 feet
