Answer: -8.93
Step-by-step explanation:
Given the function:
N(X) = 90(0.86)^x+ 69
X in the interval [0, 6]
For X = 0
N(0) = 90(0.86)^0 + 69
90 + 69 = 159
For X = 6
N(6) = 90(0.86)^6 + 69
90(0.404567235136) + 69
= 105.41105116224
Therefore, average change of change in temperature ;
(temp 2 - temp 1) / ( time 2 - time)
(105.41105116224 - 159) / (6 - 0)
= - 53.58894883776 / 6
= - 8.93149147296
= - 8.93
Answer:
Step-by-step explanation:
<span>Equation: P% * X = Y
</span>
P% = Y/X
P% = 34/675
P = 0.0504
Convert decimal to percent:
P% = 0.0504 * 100 = 5.04%
Answer:
about 4.4593 m²
Step-by-step explanation:
A foot is defined as 0.3048 meters, so the countertop has an area of ...
(16 ft)·(0.3048 m/ft) × (3 ft)·(0.3048 m/ft) = 48 ft² × 0.09290304 m²/ft²
= 4.45934592 m²
≈ 4.4593 m²
The countertop is a little less than 4.46 square meters in area.
