S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Answer: The answer is the first choice.
Explanation:
Because you must find the sin of the x values in the table.
Sin(7pi/6) = -1/2
Sin(5pi/4) = -sqrt 2/2
Sin(4pi/3) = -sqrt 3/2
<span>26 black cards of out 52
probability that a black card is chosen first = 26/52 = 1/2
</span>there are 13 heart
with replaced
The probability of then drawing a heart is 13/52 = 1/4 then
<span>the probability that a black card is chosen first and a heart is chosen second
= </span>(1/2)(1/4) = 1/8
answer
1/8
The first base matches the second height
The second base matches the first height
The third base matches the third height
<h3>Base and height of a triangle </h3>
From the question, we are to match the base to the corresponding height
In a triangle, the height of the triangle is perpendicular to the base.
Applying this in the given diagram,
The first base matches the second height
The second base matches the first height
The third base matches the third height

Yes. This is true because 4 subtracted from 8 is 8-4=4. The value you get from subtracting 4 from 8 equals the same value you would get if you were to take the value of 2 and square it. Both equal 4.
