$1. \: = > 4( - 7) \\ = 4 \times - 7 \\ = - 28$

$3. \: = > 9( - 12) \\ = 9 \times - 12 \\ = - 108$

$4. \: = > - 6( - 8.75) \\ = 6 \times 8.75 \\ = 52.5$

$5. = > 27( - 3) \\ = 27 \times - 3 \\ = - 81$

$7. \: = > - 55(0) \\ - 55 \times 0 \\ = 0$

$8. \: = > ( - 7)( - 7.25) \\ = 7 \times 7.25 \\ = 50.75$

$11. \: = > ( - 1) {}^{4} \\ = 1 {}^{4} \\ = 1$

$13. = > 42 \div ( - 7) \\ = - (42 \div 7) \\ = - 6$

$15. = > - 9 \div 3 \\ = - (9 \div 3) \\ = - 3$

What is the effect on the graph of the linear parent function, f(x) = x, when f(x) is replaced by f(x + 5)?

dedylja [7]

Answer:

D) The graph of the line shifts horizontally left 5 units.

Adding a number, n, inside of the parenthesis with x would move the parent function n units to the left.

A large washer has an outer radius of 10mm and a hole with a diameter of 14mm. What is the area of the washer? (Use π =3.14)

padilas [110]

Answer:

160.14 mm^2

Step-by-step explanation:

Area of a circle = pi r^2

subtract the area of the smaller circle from the larger

note that the smaller radius = 7 mm

pi ( 10^2 - 7^2 ) =

3.14 ( 51) = 160.14 mm^2

10. Given matrices A, B, and C below, perform the indicated operations if possible. If the operation is not possible, explain wh

Artemon [7]

Answer(a):

Order of matrix A = 3x3 {because number of rows=3, number of columns=3}

Order of matrix B = 3x3

Order of matrix C = 1x3

3A will be of order 3x3 because multiply by scalar doesn't change the order. Which is same as the order of matrix B.

So 3A+B is possible.

We simply multiply all elements of A with 3 and add them with corresponding elements of B.

$3\begin{bmatrix}2 & -1& 0\\ 0 & 5& 0.3\\ 1 & 4&10 \end{bmatrix}+\begin{bmatrix}5 & 0& 2\\ 1 & -3& 9\\ 2 & 0& 4\end{bmatrix}= \begin{bmatrix}11 & -3& 2\\ 1 & 12& 9.9\\ 5 & 12& 34\end{bmatrix}$

Answer(b):

2B will be of order 3x3 because multiply by scalar doesn't change the order. Which is NOT same as the order of matrix C.

So 2B+C is NOT possible.

Answer(c):

CA is possible only if

number of columns of C = number of columns of A

3=3

which is true hence CA is possible.

$\begin{bmatrix}1 &3 &5 \end{bmatrix}*\begin{bmatrix}2 & -1& 0\\ 0 & 5& 0.3\\ 1 & 4&10 \end{bmatrix}=\begin{bmatrix}1*2+3*0+5*1 & 1*-1+3*5+5*4 & 1*0+3*0.3+5*10\end{bmatrix}$

= $\begin{bmatrix}7 & 34& 50.9\end{bmatrix}$
