I want to solve this equation (x+2)^2

1 answer:

7 0

Okay, so powers are multiplied out of parenthesis.

Every number of a variable has 1 power.

x^2 + 2^2

x^2+4

I hope this helped!

Answer:

she added 7/12

hope it helps

Step-by-step explanation:

so 4/12 is 1/3 she reached 2/3 so she would be at 8/12. take away 1/12 cause she started with that so you get 7/12.

Point A is located at (4, 7). It will be translated 5 units right and 3 units down. Write the rule and give the location of poin

Anarel [89]

Answer:

The rule of translation is $A(x',y') = A(x,y) + (5,-3)$ .

The translated vector is $A(x',y') = (9, 4)$ .

Step-by-step explanation:

Let supposed that translation to the right is in the +x direction and translation downwards in the -y direction.

We procced to translate the operation into mathematic terms. A translation consists in a vectorial sum on a given vector. That is:

$A(x',y') = A(x,y) + U(x,y)$ (Eq. 1)

Where:

$A(x,y)$ - Original vector, dimensionless.

$U(x,y)$ - Translation vector, dimensionless.

$A(x',y')$ - Translated vector, dimensionless.

If we know that $U(x, y) = (5, -3)$ , then the rule of translation is described by:

$A(x',y') = A(x,y) + (5,-3)$ (Eq. 2)

If $A(x, y) = (4,7)$ , then the new location of A is:

$A(x',y') = (4,7)+(5,-3)$

$A(x',y') = (9, 4)$

The translated vector is $A(x',y') = (9, 4)$ .

The value in dollars, v(x), of a certain truck after x years is represented by the equation v(x) = 32,500(0.92)x. To the nearest

max2010maxim [7]

Answer:

The value of the truck is worth $27,508 after two years.

Step-by-step explanation:

We are given the following in the question:

$v(x) = 32,500(0.92)^x$

where v(x) is the value of truck in dollars after x years.

We have to estimate the value of truck after 2 years.

We put x = 2 in the equation.

$v(2) = 32500(0.92)^2\\v(2) = 27508$

Thus, the value of the truck is worth $27,508 after two years.
