Step-by-step explanation:
3c³ - 7d
= 3(-4)³ - 7(6)
= 3(-64) - 42
= -234.

Step-by-step explanation:
Answer: 69
Step-by-step explanation: The hypotenuse of the atom and it’s vastly large core equals the square root of 420 divides by 5.4 which equals 69.
The circumference of the circle is C. 61.38 cm
Answer:
<em>41.8°, 138.2° and 401.8°</em>
Step-by-step explanation:
Given the expression;

Let P = sinx
The expression becomes;
3P²+4P - 4 = 0
Factorize
3P²+6P-2P - 4 = 0
3P(P+2)-2(P+2) = 0
3P-2 = 0 and P+2 = 0
P = 2/3 and -2
When P = 2/3
sinx = 2/3
x = arcsin 2/3
x = arcsin 0.6667
x = 41.8 degrees
Also if P = -2
sinx = -2
x = arcsin (-2)
x will not exist in this case
To get other values of x
sin is positive in the second quadrant
x = 180 - 41.8
x = 138.2°
x = 360+41.8
x = 401.8°
<em>Hence the values of x within the interval are 41.8°, 138.2° and 401.8°</em>
