Answer: 21.4
Step-by-step explanation:
Area of a triangle = (1.7 * 2)/2=1.7 m2
Area of a rectangle = 3 * 2 = 6 m2
3 * 6 = 18 m2 2 * 1.7 = 3.4 m2
the total area is 18 + 3.4 = 21.4 m2
Answer:
14
Step-by-step explanation:
Total number of chips = 500
Percentage of green chips = 28%
P(green chips) = 0.28
Expected number of green chips from a simple of 50
Sample size, n = 50
p of green chips = 0.28
Recall:
Mean, m = n*p
Expected number of green chips = 50 * 0.28 = 14
14 green chips
Congruent means the same or identical
so if you have two right angle they are both congruent to each other
Answer: True
The given quadratic function is:

The zeros of the quadratic functions also known as its roots can be found using the quadratic formula.
According to the quadratic formula:

here,
b = coefficient of x-term
a = coefficient of x²-term
c = costant term
For given function:
a = 2
b = 8
c = - 3
Using these values in the formula, we get:

Thus, these values of x are the zeros of the given quadratic function f(x)=2x²+8x-3
