Answer:

SA = 31.714 km²

Step-by-step explanation:

SA = πr² + πrl

SA = 3.14(1)² + 3.14(1)(9.1)

SA = 3.14 + 28.574

SA = 31.714 km²

Find a,b,c and d?..........
cupoosta [38]

9514 1404 393

Answer:

  a = 6, b = 12, c = 6, d = 6√3

Step-by-step explanation:

The two triangles are the "special" triangles.

The 45-45-90 triangle has side lengths in the ratios 1 : 1 : √2.

The 30-60-90 triangle has side lengths in the ratios 1 : √3 : 2.

Then ...

  c : a : 6√2 = 1 : 1 : √2   ⇒   c = a = 6

and ...

  a : d : b = 1 : √3 : 2   ⇒   d = 6√3 and b = 12 . . . (since a=6)

The lengths are ...

  a = 6, b = 12, c = 6, d = 6√3

What is the midpoint of a segment with These endpoints (-12,-3) and (3,-8)
Savatey [412]

Answer:

(\frac{-9}{2},\frac{11}{2})

Step-by-step explanation:

you have to use the midpoint formula which is

(\frac{x1+x2}{2},\frac{y1+y2}{2})

so you plug your numbers in

(\frac{-12+3}{2},\frac{-3+-8}{2})

Add the tops

(\frac{-9}{2} ,\frac{-11}{2} )

if possible simplify

and that is your answer

Suppose that det(a) = a b c d e f g h i = 2 and find the determinant of the given matrix. a b c −4d −4e −4f a + g b + h c + i
zhuklara [117]
I'll go out on a limb and suppose you're given the matrix

\mathbf A=\begin{bmatrix}a&b&c\\d&e&f\\g&h&i\end{bmatrix}

and you're asked to find the determinant of \mathbf B, where

\mathbf B=\begin{bmatrix}a&b&c\\-4d&-4e&-4f\\a+g&b+h&c+i\end{bmatrix}

and given that \det\mathbf A=2.

There are two properties of the determinant that come into play here:

(1) Whenever a single row/column is scaled by a constant k, then the determinant of the matrix is scaled by that same constant;

(2) Adding/subtracting rows does not change the value of the determinant.

Taken together, we have that

\det\mathbf B=-4\det\mathbf A=-8
