Answer:
40°
Step-by-step explanation:
The side adjacent to the angle of interest and the hypotenuse are given, so the cosine relation is relevant.
Cos = Adjacent/Hypotenuse
cos(?) = 46/60
? = arccos(46/60) ≈ 39.9445°
? ≈ 40°

Answer: 62.8
Step-by-step explanation:
2 x 3.14 x 10
Answer:
Step-by-step explanation:
A is a quadratic. Quadratics are not linear. It contains an x^2 term.
B isn't really a true value for a solution to a linear equation because there are x's on both sides of the equation. They can be divided out leaving you with 12 = 17.
C is linear It has 1 solution The answer to C is 3.64
D is linear it has 1 solution The answer to D is 5/12
Both C and D have only 1 solution each. That is one of the characteristics of linear equations.
Answer:
Smax = 676 ft
the maximum altitude (height) the rocket will attain during its flight is 676 ft
Step-by-step explanation:
Given;
The height function S(t) of the rocket as;
S(t) = -16t2 + 208t
The maximum altitude Smax, will occur at dS/dt = 0
differentiating S(t);
dS/dt = -32t + 208 = 0
-32t +208 = 0
32t = 208
t = 208/32
t = 6.5 seconds.
The maximum altitude Smax is;
Substituting t = 6.5 s
Smax = -16(6.5)^2 + 208(6.5)
Smax = 676 ft
the maximum altitude (height) the rocket will attain during its flight is 676 ft
