Answer:
126 units
Step-by-step explanation:
the lateral area of a regular pyramid with a square base of 126 units has a slant height of 9 units and base side lengths of 7 units.
For
the derivative is negative.
For
the derivative is positive.
Therefore at
there's a minimum.
Answer:
a
Step-by-step explanation:
Here the NULL hypothesis will be difference in weeks at which baby is delivered is zero between groups of women who were exposed to air pollution and group of women who were not exposed to air pollution
The cosine of an acute angle in a right triangle <span> is the ratio of the length of the adjacent side to the length of the hypotenuse.
</span>If cos(x)=1/2, then:
the adjacent side = 1
the hypotenuse = 2
<span>By the Pythagorean theorem:
</span>the opposite side = √(2² - 1²) = √(4-1) = √3
The sine<span> of an angle is the ratio of the length of the opposite </span>side<span> to the length of the hypotenuse, so:
</span>sin(x) = opposite/hypotenuse = √3/2
The tangent<span> of an angle is the ratio of the length of the opposite side to the length of the adjacent side:
</span>
tan(x) = opposite/adjacent =√3/1 = √3
