[5 2 1]
Answer:
Step-by-step explanation:
For the multiplication of two matrices, number of columns in 1st matrix should be equal to the number of rows of the 2nd matrix.
In the given question,
1st matrix → [tex]\begin{bmatrix}2 & 8 & 1\\ 0 & 5 & -2\end{bmatrix}[/tex]
Number of columns in this matrix = 3
2nd matrix → [5 2 1]
Number of rows in this matrix = 1
Therefore, number of columns in 1st matrix are not equal to the number of rows in the 2nd matrix.
Therefore, multiplication of matrices given in the picture is "Impossible".

Answer: 127 11/12
Step-by-step explanation:
1. 1/2 + 3/4 = 2/3
Change 1/2 by by multiplying by 2 to get a common denominator of fourths.
2/4 + 3/4 = 2/3?
5/4 = 2/3?
no
2. 5/8 - 1/4
Change 1/4 by by multiplying by 2 to get a common denominator of eighths.
5/8 - 2/8 = 3/8?
3/8 = 3/8 ?
yes
3/8 x 10 = 30/8
3. 4/5 +7/10 = 1 1/2
Change 4/5 by multiplying by 2 to get a common denominator tenths.
8/10 + 7/10 = 1 1/2?
15 /10 = 1 1/2?
yes
1 1/2 x 10 = 25
4. 2 1/3 - 1 5/6 = 1/6
Change 1/3 by multiplying by 2 to get a common denominator sixths.
2 2/6 - 1 5/6 = 1/6?
3/6 = 1/6
no
100 -2/3 - 1/6 + 30/8 + 25
multiply the thirds by 8. Sixths by 4. Eighths by 3 to get a common denomonator of 24ths.
100 - 16/24 - 4/24 + 90/ 24 + 25 = 125 70/24

All exponential functions can be written in many forms. Write the function f(t)=110(1.35)^{\frac{t}{40}}f(t)=110(1.35) 40 t in the form f(t)=ae^{kt}f(t)=ae kt . Round all coefficients to four decimal places.
Step-by-step explanation:
Given - f(t)=110(1.35)^{\frac{t}{40}}
To find - Write the function in the form f(t)=ae^{kt}. Round all coefficients
to four decimal places.
Proof -
Given that , the function is f(t)=110(1.35)^{\frac{t}{40}}
Now,
We can write it in the form of [tex]f(t) = 110(1.35)^{\frac{t}{40} }[/tex]
By comparing with the form [tex]f(t) = ae^{kt}[/tex] , we get
a = 110.0000
k = [tex]\frac{1}{40}[/tex] = 0.0250

x=−4, y=−6
The variables x and y vary inversely. Use the given values to write an equation relating x and y. Then find y when x=−3.
x=−4, y=−6
Answer:
xy-3x=40, x=5
x(y-3)=40
y-3=(40/x)
y=(40/x)+3
y=(40/5)+3
y=8+3
y=11
If the variables x and y vary inversely then when x=-3 and y =-8
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Since x and y vary inversely, we can write the equation:
x y = k, where k is a constant of variation.
Using the given values, we can find k:
(-4)(-6) = k
k = 24
So the equation relating x and y is:
x y = 24
To find y when x = -3, we substitute x = -3 into the equation and solve for y:
(-3) y = 24
y = -8
Therefore, when x = -3, y = -8.

Kenny buys a new drill for $129.90 plus 9.5% sales tax. How much does Kenny pay in total?Round the answer to the nearest cent.
Answer:
Kenny pays $142.24 in total.
Step-by-step explanation:
In order to find the total amount that Kenny pays, you have to calculate the 9.5% of the price of the drill as this is the sales tax and then, you have to add that amount to the price:
$129.90*9.5%=$12.34
$129.90+$12.34=$142.24
According to this, the answer is that Kenny pays $142.24 in total.

Find the indicated term of each sequence by repeatedly multiplying the first term by the common ratio. Enter your answer to 5 decimal places if necessary. Use a calculator.
−30, 6, −1.2, ...; 5th term
The 5th term of the sequence is
Answer:
-0.048
Step-by-step explanation:
-30 * -1/5 = 6
6 * -1/5 = -1.2
(Remember -30 is first term so we subtract 1 from 5 in the exponent)
-30 * (-1/5)^4 = -0.048

If y is directly proportional to Vx, and y = 25 when x = 3, find x when
y = 100
9514 1404 393
Answer:
x = 48
Step-by-step explanation:
It looks like your proportion is ...
y = k√x
Then k can be found as ...
k = y/√x = 25/√3
__
For y = 100, the value of x can be found from ...
100 = (25/√3)√x
4√3 = √x . . . . . . . . . . multiply by √3/25
48 = x . . . . . . . . . . . . . square both sides

Raul is cutting boards for a project. He has a board that measures 8 feet and is cutting it into 3/4 foot pieces. How many whole pieces of 3/4 foot will he be able to cut?
Answer:
10
Step-by-step explanation:
1 board = 3/4 foot = 0.75 of a foot
x boards = 8 feet
1/x = 0.75 / 8 feet Cross multiply
0.75 x = 8 Divide both sides by 0.75
x = 8/0.75
x = 10 2/3 boards.
We are told to throw the fractional board away so Raul will get 10 pieces from an 8 foot piece of lumber.
Which property is shown In the matrix addition above?
A. Inverse Property
B. Identity Property
C. Commutative Property
D. Associative Property
Answer :
Identity Property.
Step-by-step explanation:
Two matices are given to us , which are ,
Let A = [tex]\left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] [/tex] .
Let B = [tex]\left[\begin{array}{ccc} 0 & 0& 0 \\ 0 & 0 & 0 \end{array} \right] [/tex] .
Here since all the elements of Matrix B are 0 , its a null matrix . Hence adding any matrix to it will give the same matrix which is added . This property is called as Identity Property .
Adding both A and B ,
[tex]\implies A + B = \left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] + \left[\begin{array}{ccc} 0 & 0& 0 \\ 0 & 0 & 0 \end{array} \right] [/tex]
[tex]\implies A + B = \left[ \begin{array}{ccc} ( 6+0) & (-8+0) & (1+0) \\ (0+0) & (-2+0) & (-19 + 0 ) \end{array}\right] [/tex]
[tex]\red{\implies A + B = \left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] }[/tex]

A motorist drives 146km at a certain speed. She then increase this speed of by 19km/hr and take the same time to travel the next 16km. Find her speed for both part of the journey. Pleaseeeeeeeeeeee helpppppppppppp
Step-by-step explanation:
A motorist drives 146km at a certain average speed she then increases the speed by 9km/h and takes the same time to travel the next 164km.
find her speeds for both parts of the journey.
:
let s = his original speed
then
(s+9) = the increased speed
:
Write a time equation; time = dist/speed
146%2Fs = 164%2F%28%28s%2B9%29%29
cross multiply
164s = 146(s+9)
164s = 146s + 1314
164s - 146s = 1314
18s = 1314
s = 1314/18
s = 73 km/h is his original speed

What is division?The division is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
A recipe uses 350 grams of rice, The recipe serves 4 people,
Calculate the quantity of rice for serving one person as shown below,
The quantity of rice for one people = Total quantity of rice / total number of people
The quantity of rice for one people = 350 / 4
Calculate the quantity of rice for 10 people as shown below,
The quantity of rice for 10 people = 350 / 4 × 10
The quantity of rice for 10 people = 3500 / 4
The quantity of rice for 10 people = 875
