Sad is sad, it's that feeling of loneliness mixed with bitterness, it just makes you unhappy.
Step-by-step explanation:
Sad is blue or unhappy, this can be caused by well loneliness and stress, and other stuff.
Answer:
4.5
Step-by-step explanation:
To find the instantaneous rate of chance, take the derivative:
Remember to use power rule:
To differentiate -2/x, think of it as:
Then, substitute 2 for x:
X² + 2x = 24
Organizing:
x² + 2x - 24 = 0
<<<< (<em>Quadratic </em><span><span><em>equation</em>)
</span>
</span><span>Delta:
</span>Δ = b²<span> - 4.a.c </span>
Δ = 2²<span> - 4 * 1 * -24 </span>
<span>Δ = 4 - 4 * 1 * -24 </span>
Δ = 100
<span>Bhaskara:
</span><span>x = (-b +- √Δ)/2*a
</span>
x' = (-2 + √100)/2*1
x' = 8 / 2
x' = 4
x'' = (-2 - √100)/2*1
x'' = -12 / 2
x'' = -6
Result: x = 4 or<span> x = - 6 .

Good studies! :)
Let x = 78.3
y = 87.2
σₓ = 5.6 and σ₍y₎ = 6.3
number of pieces n = 50
z = z-score value =1.96 in this case
<span> A 100(1-α)%
confidence interval for the difference in large sample means is:
(x – y) ± z x </span>√( σₓ² / n+ σ₍y₎²<span>/n)
by putting the values,
=(78.3-87.2) </span>± 1.96 x √(5.6² /50 + 6.3² /50)<span>
</span><span>= -8.9 ± 2.34
</span><span>= [-11.24, -6.56]</span>
For this case, the first thing you should know is that there are two possible cases:
Case 1:
If 0 <k <1 then there is a reduction of the orignal figure.
Case 2:
If k> 1 then there is an expansion of the originial figure.
Therefore, in this case, the scale factor that represents a reduction is given by:
k = 3/4 = 0.75 (0 <k <1)
Answer:
the dilation that would represent a reduction is:
C. k = 3/4
