What is the product

Answer:

$\left[\begin{array}{cc}6&18\\\end{array}\right]$

Step-by-step explanation:

To find the product of the matrices: $\left[\begin{array}{cc}4&2\\\end{array}\right]$ × $\left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]$

Multiply rows of the first matrix by the columns of the second matrix.

(4 × (–2) + 2 × 7 4 × 5 + 2 × (–1))

After simplifying this, we get the product $\left[\begin{array}{cc}6&18\\\end{array}\right]$

Hence, $\left[\begin{array}{cc}4&2\\\end{array}\right]$ × $\left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]$ = $\left[\begin{array}{cc}6&18\\\end{array}\right]$

Solving an Equation for a Given Variable

Reil [10]

Answer:

$a=\frac {f-v}{t}$

Step-by-step explanation:

f=v+at

It requires you to make a the subject of the formula

f-v=at

Dividing both sides by t then

$a=\frac {f-v}{t}$

Therefore, the equivalent for a is $a=\frac {f-v}{t}$
