Step-by-step explanation:
since the other angles are equal to each other, both triangles, TQR and TSR, are identical. they are just oriented differently.
but that also means that both angles, Q and S, are identical too.
so,
2x² = 3x² - 64
64 = x²
x = 8
and therefore, both angles are 128°.
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)

(2^2 * 2^3) / (2^4) =
2^5 / 2^4 =
2^1 <== answer is B
** when multiplying exponents with the same base, keep the base and add the exponents. 2^2 * 2^3 = 2^(2 + 3) = 2^5
** when dividing exponents with the same base, keep the base and subtract the exponents. 2^5 / 2^4 = 2^(5 - 4) = 2^1
Answer:
w² - 2w + 4
Step-by-step explanation:
(w² - 4w + 14) - (2w + 10) = w² - 2w + 4
Answer/Step-by-step explanation:
Total Distance = 3Ft
a) Determine the amplitude and period of a sinusoidal function that models the bobbing buoy.
Amplitude = 3/2 = 1.5 period = 10 second
No ph. Shift
b) Write an equation of a function that models the buoy with x=0 at its highest point.
y= 1.5 cos ( )
