Answer:

6.25

Step-by-step explanation:

V=lwh /3

To account for the 2/3 slant, add 1

2.5X2.5X3/3 = 6.25

If this is incorrect, I'm sorry. But this seemed to be the most plausible answer based on how far away the other numbers are and how it matches perfectly with the answer choice

Answer:

Step-by-step explanation:

height of pyramid = √(10²-(5/2)²) = √93.75

volume of pyramid = ⅓b²h = ⅓·5²√93.75 ≅ 80.69 in³

lateral area = 2×5×10 = 100 in²

base area = 5² = 25 in²

surface area = 100+25 = 125 in²

Vector v has a direction of (-4,27) find the direction angle for v

mixas84 [53]

$\bf \begin{array}{lclll}
\ \textless \ &-4&,&27\ \textgreater \ \\
&\uparrow &&\uparrow \\
&a&&b
\end{array}\qquad tan(\theta)=\cfrac{b}{a}\implies \measuredangle \theta=tan^{-1}\left( \frac{b}{a} \right)
\\\\\\
\measuredangle \theta=tan^{-1}\left( \frac{27}{-4} \right)$
