Answer:3x^2+8x-16
Step-by-step explanation:
Answer:
X = 7.2
Step-by-step explanation:
Hello
For the triangle of right side, using Pytagoras:
(2.5)^2 + b^2 = 6^2
6.25 + b^2 = 36
b^2 = 36 - 6.25
b^2 = 29.75
b = 5.45
Now we can to find X using again Pytagoras:
3^2 + (5.45)^2 = x^2
9 + 29.75 = x^2
38.75 = x^2
X = 7.2
Best regards
Answer:
a) 16.66%
b) 5%
Step-by-step explanation:
a)
Since the teacher assumes each of the three possibilities are equally likely, then he assumes 33.33% to each one.
In this case the probability that you traveled to school that day by car would be
50% of 33.33% = (0.5)(0.3333) = 0.1666 = 16.66%
b)
In this case, the teacher would assume
90% ride on bicycle
0% take the bus
10% travel by car
So, in this case the probability would be
50% of 10% = (0.5)(0.1) = 0.05 = 5%
Answer:
Step-by-step explanation:
f(x) = (1/2) *6^x = 2^-1 * 2^x *3^x
y= 2^ (x-1) * 3^x
Domain represents all values that x can have and is all real numbers
Range all values that y can have and is y > 0 ( all real numbers that are positive)
The y-intercept is the point where the graph intersects the y-axis so x=0 there
y = 2^(0-1) *3^0 = 1/2 *1 = 1/2
the asymptote is at y= 0
Answer:
Step-by-step explanation:
1) 5
2) -3, which becomes 3
3) it would land at either 3, or -3
4) 7 or -7
5) if it is to the left, that means it is negative. there fore, your answer is -4
