4 0

Answer:

1) n^2 – 3 n + 8   4^2 – 3*4 + 8 = 12    

2)    (x^2 – 4 y) / 2      (16 + 12) / 2 = 14

3) 4 * |-7 – 2| = 4 * 9 = 36     Abs -9 = 9  

4) 19 – x^2 = 19 – 25 = -6     (-5)^2 = 25

5) S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38

6) 4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) =  - 20      (-2)^3 = -8

Solve 3 -x = 243 -5 1/5 5
Paraphin [41]

Answer:

x=-243

Step-by-step explanation:

The equation is

-3^{-5}=\frac{1}{x}

Solve for x

we know that

-3^{-5}=-\frac{1}{3^{5}}=-\frac{1}{243}

substitute

-\frac{1}{243}=\frac{1}{x}

so

x=-243

A coin is tossed three times. what is the probability of getting two heads and one tail?
Lera25 [3.4K]
If the order doesn't matter, then the probability is 37.5%
If it has to be head head tail, then the probability is 12.5%

If the order doesn't matter, the possible outcomes that have two heads and one tail are HHT, HTH, and THH. Since these all have a probability of 12.5% of occuring, the probability of any of them occuring is 37.5%

Somebody, please help
SashulF [63]
F(x) can be written as:
f(x) = Asin(2x); where A is the amplitude and the period of the function is half that of a normal sin function.
f(π/4) = 4
4 = Asin(2(π/4))
4 = Asin(π/2)
A = 4
Amplitude of g(x) = 1/2 * amplitude of f(x)
A for g(x) = 2
g(x) = 2sin(x)
