Answer:

(2,6)

Step-by-step explanation:

The options of the questions are

(0,1) (1,3) (2,6) (3,27)

and the given function is $y=3^x$

we know that

If a ordered pair lie on the graph of the given equation, then the ordered pair must satisfy the given equation

Verify each ordered pair

case 1) (0,1)

substitute the value of x and the value of y in the linear equation and then compare the results

$1=3^0$

$1=1$ ----> is true

The ordered pair lie on the graph of the given equation

case 2) (1,3)

substitute the value of x and the value of y in the linear equation and then compare the results

$3=3^1$

$3=3$ ----> is true

The ordered pair lie on the graph of the given equation

case 3) (2,6)

substitute the value of x and the value of y in the linear equation and then compare the results

$6=3^2$

$6=9$ ----> is not true

The ordered pair not lie on the graph of the given equation

case 4) (3,27)

substitute the value of x and the value of y in the linear equation and then compare the results

$27=3^3$

$27=27$ ----> is true

The ordered pair lie on the graph of the given equation

Leonardo da vinci took out A simple interest loan at 12.75% interest for 12 months. His previous balance is % 942.36. What is hi

makkiz [27]

Answer:

A = 2,384.1708

Step-by-step explanation:

A = P(1 + rt)

P = 942.36

r = 12.75%

t = 12 months

A = 942.36(1 + 12.75/100(12))

A = 942.36(2.53)

A = 2,384.1708

Please help math middle school level

pychu [463]

Answer:

7 yd

Step-by-step explanation:

You are finding the perimeter. Your answer should include yd (yd² is for area, yd³ is for 3d images).

Note that the two lines segments (? & 9) is parallel to the other line segment (16). Find the ?:

? + 9 = 16

? + 9 (-9) = 16 (-9)

? = 16 - 9

? = 7

7 yd is your answer

The temperature at a point (x, y, z) is given by T(x, y, z) = 300e−x2 − 3y2 − 7z2 where T is measured in °C and x, y, z in meter

Elenna [48]

Answer:

Rate of change $24^{\circ}$ C per meter.

Step-by-step explanation:

Given,

$T(x,y,z)=300e-x_{2}-3y_{2}-7z_{2}$

Then,

$T_{x_2}=-1, T_{y_2}=-3, T_{z_2}=-7$

Change of temperature at the point say, $(x,y,z)=(2,-1,3)$ along the direction say, $(u,v,w)=(6,-4,6)$ is,

$\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}$

$=(6\times -1)+((-4)\times (-3))+(3\times 6)$

= $24$

Hence the rate of change of temperature is $24^{\circ}$ C per meter.

What is the value of x ?

4vir4ik [10]

Answer:

What is the value of x?

Whenever we have a problem to solve we assume the unknown quantity(or value to be identified) as x. This is just a convention followed in algebra by using a variable to denote the unknown quantity and then arrive at the solution.

What is the value of X?

What's the value of X?

X + X = X, what is the value of X?

What is the value of x ? How can I find it?

Do you know the value of x?

Value of X can be any numerical value or anything but depends solely on your question .But I find no question ok lets take an example .

If an equation is given ,

X+2=4

=> X=4–2

=>X=2

We X's value as 2 .

Now another ,

X + Y = 5 , 2X + 5Y = 10

Now taking first equation

X = 5-Y ………………………..(1)

Now taking second equation

X= 10–5Y/2…………………(2)

Now,

2(5-Y) = 10–5Y

=> 10–2Y = 10–5Y

=> 2Y = 5Y

Y has no value here because this equation not correctly represented .

Hence ,

We conclude the value of X varies with equation .

Thank You ,
