I am very stuck with this

Bingel [31]

Answer:

see explanation

Step-by-step explanation:

To multiply the vector by a scalar, multiply each of the elements by the scalar.

To add 3 vectors add the corresponding elements of each vector

2a + 3b + 4c

= 2 $\left[\begin{array}{ccc}2\\3\\\end{array}\right]$ + 3 $\left[\begin{array}{ccc}-4\\1\\\end{array}\right]$ + 4 $\left[\begin{array}{ccc}3\\2\\\end{array}\right]$

= $\left[\begin{array}{ccc}4\\6\\\end{array}\right]$ + $\left[\begin{array}{ccc}-12\\3\\\end{array}\right]$ + $\left[\begin{array}{ccc}12\\8\\\end{array}\right]$

= $\left[\begin{array}{ccc}4-12+12\\6+3+8\\\end{array}\right]$

= $\left[\begin{array}{ccc}4\\17\\\end{array}\right]$

Please Help!!<br> f(x) = square root of x plus 7 ; g(x) = 8x -11 <br> Find f(g(x))

Sonja [21]

I'm not sure if you mean ( $\sqrt{x + 7}$ ) or ( $\sqrt{x} + 7$ ) I solved it both ways .

$f(x) = \sqrt{x + 7} \\ \\ f( \: g(x) \: ) = \sqrt{(8x - 11)+ 7} \\ = \sqrt{8x - 11 + 7} \\ = \sqrt{8x - 4} \\ = 2 \sqrt{2x - 1}$

____o_____o______

$f(x) = \sqrt{x} + 7 \\ \\ f( \: g(x) \: ) = \sqrt{(8x - 11)} + 7 \\ = \sqrt{8x - 11} + 7\\$

I hope I helped you^_^

Misha increased her test score from 60% to 80%.. What was the approximate percent increase of Misha's test score?. 25%. 33%. 66%

Anvisha [2.4K]

we know that

Using the original score as the basis

If Misha increased her test score from $60$ % to $80$ %

then

the increase variation is equal to

$80$ %- $60$ %= $20$ %

to find the approximate percent increase of Misha's test score we apply a rule of three

if $60$ %--------------> represents $100$ %

$20$ %----------------->x

$x=20*100/60$

$x=33.33$ %

therefore

the answer is

the approximate percent increase of Misha's test score is $33$ %
