How is multiplying exponents (x^2*x^4) different from raising a power to a power((x^2)^4)? Ty =)

Contact [7]

Answer:

When your multiplying exponents in the same parenthasis like x^2*x^4, you'll add the exponents so it will be x^6. If it is outside the parenthasis like (x^2)^4 you'll multiply the exponents so it will be x^8. good luck! :)

Nathan has just bought a new car. He models the value, V, in dollars, of the car after t years as V(t) = 21,000(0.861)t. Based o

UkoKoshka [18]

Answer:

13.9%

Step-by-step explanation:

The value of car is modeled as:

$V(t)=21,000(0.861)t$

Here we can see that, each year Nathan has considered 0.861 of the previous year value or we can say that Nathan has considered 86.1% of the previous year value. So,

$100-86.1=13.9$

We subtract the percentage value considered from 100 to find out the percentage decrease in the value of the car.

The value of new car is decreasing by 13.9% each year.

Solve the system of equations by graphing where f(x)=5-2x and g(x)=(2/3)x-2. What is the value of x? 0 1 2 3 4

vfiekz [6]

Answer:

The graph is uploaded in the attachment.

The value of x is 2.625.

Step-by-step explanation:

let us plot f(x), g(x) on y-axis

so, f(x)=y and g(x)=y.

the first equation can be written as y=5-2x

the general equation of a straight is y=mx+c

( where m is the slope and c is the y-intercept )

now comparing given equation with the general equation mentioned above, the slope of first line is -2 and its y-intercept is 5

the slope of second equation i.e, y=(2/3)x-2 is 2/3 and its y-intercept is -2.

now plot the graph using above information.

(y-intercept is the the coordinate of a point where the line intersects y-axis)

(slope is the angle made by the line with the x-axis)

by seeing the graph, the value of x is 2.625.
