Answer attached
Step-by-step explanation:
ST
3*-2 + 4*-4 = -22 3*0 + 4*5 = 20
-1*-2 + -2*-4 = 10 -1*0 + -2*5 = -10
try TS by yourself
the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].
Given that,
[tex]S=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex] and [tex]T=\left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]
What is the product of two matrix?The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.
Now, [tex]ST=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right] \times \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]
[tex]ST=\left[\begin{array}{cc}(-6-16)&(0+20)\\(2+8)&(0-10)\end{array}\right][/tex]
[tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex]
[tex]TS= \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right]\times \left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex]
[tex]TS=\left[\begin{array}{cc}(-6-0)&(-8-0)\\(-12-5)&(-16-10)\end{array}\right][/tex]
[tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex]
Therefore, the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].

How much force is needed to push a 10kg ball to an acceleration of 0.8 m/s2?
Answer:
Mass of the object (m)= 10kg
Acceleration of the object (a)= 2m/s^2
Force acting on the object (F)= ?
Solution
F = m × a
F = 10 × 2
F= 20N
The force acting on the object is 20N.
Step-by-step explanation:
8N of force is needed to push a 10kg ball to an acceleration of 0.8 m/s²
What is Force?Force is an influence that can change the motion of an object.
Given,
Mass of the object (m)= 10kg
Acceleration of the object (a)= 0.8m/s²
We need to find Force acting on the object (F)= ?
Force=Mass ×Acceleration
F = m × a
Plug in the values of mass and acceleration
F =10 × 0.8
F= 8N
Hence, The force acting on the object is 8N.

The length of the subway is 113 miles. if 4.1 inches represents 677 miles, what is the length of the subway on the map? Round your answer to the nearest
hundredth if needed.
Answer:
0.68 inches (nearest hundredth)
Step-by-step explanation:
First, find the length on the map that represents 1 mile of the subway.
677 miles ----- 4.1 inches
1 mile ----- 4.1 ÷ 677= 0.0060561 inches (5 s.f.)
Multiply both sides by 113:
113 miles ----- 113(0.0060561)= 0.68 inches (nearest hundredth)
Thus, the length of the subway on the map is 0.68 inches.

2, 4, 5, 7, 10452.16 rounded to the nearest tenth
Answer: 452.2
Step by Step Explanation: Find the number in the tenth place 1 and look one place to the right for the rounding digit 6 round up if this number is greater than or equal to 5 and round down if it is less than 5
.
Rounding 452.16 to the nearest tenth gives us: 452.1.
Given that we need to round 452.16 to the nearest tenth,
We look at the digit in the hundredth place, which is the second decimal place, and round 452.16 to the nearest tenth.
One is the digit at the hundredth position.
We round down because 1 is less than 5, therefore.
Simply drop all the digits following the tenths place and leave the tenths place digit alone if you want to round down.
Rounding 452.16 to the nearest tenth, we obtain: 452.1.
Hence rounding 452.16 to the nearest tenth gives us: 452.1.
