Answer:
Below in bold.
Step-by-step explanation:
(a) Using the Pythagoras theorem:
30^2 = 21^2 + p^2
p^2 = 30^2 - 21^2 = 459
p = √459
= 21.4 cm to nearest tenth.
(b) cos P = 21/30 = 0.70
m < P = 45.57 degrees to nearest hundredth.
Answer:
6
Step-by-step explanation:
The opposite of -3 is 3. Opposite numbers are numbers that when added, sum to 0. The distance between 3 and -3 is |3 - (-3)| = |3 + 3| = |6| = 6.
8 + 0.15m = 22 + 0.10m
0.15m - 0.10m = 22 - 8
0.05m = 14
m = 14/0.05
m = 280
Answer: <em><u>280 minutes</u></em>
Since there are decimals you could round the decimals to the nearest tenth.
The other x-intercept is (2,0)
