[tex] \\ \sf16 {x}^{0} + 2 {x}^{2} \times {y}^{ - 1} [/tex]

Now putting the values of x and y.

[tex] \\ \sf16 \times {2}^{0} + 2 \times {2}^{2} \times {4}^{ - 1} [/tex]

[tex] \\ \sf = 16 \times 1 + 2 \times 4 \times \frac{1}{ {4}}[/tex]

[tex] \\ \sf = 16 + 2[/tex]

[tex] \\ \sf = 18[/tex]

Note:

•If the power of a number is 0 then it's value will be 1.

•If the power of a number is negative then reciprocal the number to make the power positive.

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.

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]

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].

Answer:

150 Miles

Step-by-step explanation:

30 * 5miles = 150

Answer:

y = 3

Step-by-step explanation:

If the line needs to be parallel to the x axis, it must be Horizontal. The formula for lines like this is y= mx+c with m being the gradient. With a horizontal line, the gradient is 0 and therefore we get y=c.

To find c, we need to find the y intersect which is where the line passes through the y axis. Since it is horizontal and passes through the dot, we can find that c = 3 as the dot is at 3 on the vertical axis.

From this, we can see that the equation is y = 3.

Answer:

3

Step-by-step explanation:

the x-axis is horizontal and the numbers above and below it are 4 and 2 and the dot was right on the line so it was 3

90-80 x 2-2 = 0

Step-by-step explanation:

Firstly. subtract 80 from 90 to get 10.

90-80= 10

Then subtract 2 from 2, to get 0.

2-2=0

Lastly, for your answer multiply 10 by 0 to get 0.

Answer:

0.05 in decimal form or 1/20

Step-by-step explanation:

Since there are 20 blocks, we are going to divide 1 by 20.

Result: 00.5

To get it in fraction form we are going to multiply 1/4 by 1/5 and get 1/ 20 because 4 x 5 = 20. There is no way to simplify this.

Therefore, your answer would be 1/20.

Answer:

Step-by-step explanation:

you have to split it up mostly

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

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.
