Answer:

In the given expression the coefficient of x is 3

Step-by-step explanation:

Given that Jill simplified the expression shown

4x-2y-x+5y-8

we have to find the coefficient of the x-term of the fully simplified expression.

Expression:

4x-2y-x+5y-8

Combining like terms, we get

4x-x-2y+5y-8

3x+3y-8

Hence, in the above expression the coefficient of x is 3

Find the maxmium area of a rectangular plot of land which can be enclosed by rope of length 60 metres​
mario62 [17]

Answer:

225 m²

Step-by-step explanation:

If W is the width of the rectangle, and L is the length, then:

60 = 2W + 2L

A = WL

Use the first equation to solve for one of the variables:

30 = W + L

L = 30 − W

Substitute into the second equation:

A = W (30 − W)

A = 30W − W²

This is a parabola, so we can find the vertex using the formula x = -b/(2a).

W = -30 / (2 × -1)

W = 15

Or, we can use calculus:

dA/dW = 30 − 2W

0 = 30 − 2W

W = 15

Solving for L:

L = 30 − W

L = 15

So the maximum area is:

A = WL

A = (15)(15)

A = 225

NEED HELP ASAP PLEASE

Answers:

  • interest = $75
  • balance at maturity = $3075

=============================================================

Explanation:

The simple interest formula is

i = p*r*t

where in this case,

  • p = 3000 = principal (amount deposited)
  • r = 0.10 = annual interest rate in decimal form
  • t = 3/12 = 0.25 = number of years

So,

i = p*r*t

i = 3000*0.10*0.25

i = 75 is the amount of interest earned

This adds onto the initial deposit to get the final balance when the CD matures (ie when you're able to withdraw the money without penalties)

The balance at maturity is p+i = 3000+75 = 3075 dollars

---------------

In short, you deposit $3000 into the CD and have to wait 3 months for the amount to update to $3075.

1.901 x 10^-7 in standard notation
WITCHER [35]

Answer:

In standard form, it would be 0.0000001901!

Step-by-step explanation:

As you can see, if the exponent is negative, the answer would be a decimal so moving the decimal place 7 times to the left, that would be your answer.
