82°
Step-by-step explanation:
The acute angles in a right triangle are complementary. The other one is ...
90° -8° = 82°
Answer:

Step-by-step explanation:
We want to model the position of the submarine as a function of time.
Notice that we have a constant amount. The initial depth: 750 meters
Then we have a factor that varies over time. Every hour the submarine ascends 50 meters. therefore as t increases the depth y(t) of the submarine decreases. Then the factor is:
-50t.
Where t represents the time in hours.
Then the equation that represents the new position of the submarine in relation to the level of the sea:

Since 216 is the cube of 6, 64 is the cube of 4 and x^3 is the cube of x, we have

so the expression is the sum of the cubes of 6x and 4

Question 1:
Add the following:
(i) 3x and 7x
(ii) −5xy and 9xy
ANSWER:
We have
(i) 3x + 7x = (3 + 7)x = 10x
(ii) -5xy + 9xy = ( -5 + 9)xy = 4xy
Answer:
15 feets, 11.25 inches
Step-by-step explanation:
Given that:
Scale = 1 : 48
Thus means that the model is 1/48 the actual size of the jet
Length of fighter jet = 63feets, 9 inches
Converting the entire length to inches
1 feet = 12 inches
63 feets = (12 * 63) = 756
Lenght of jet = (756 + 9) = 765 inches
1/48 * 765 = 15.9375 ; 15 feets, 11.25 inches
Hence, length of model = 15 feets, 11.25 inches
