The answer you are looking for is -11/10 or - 1 1/10.

To find this answer you must first make the denominators the same. To do this, multiply 2/5 by 2/2 to get 4/10. Finally, subtract the two fractions, keeping in mind the denominators stay the same. -7/10 - 4/10 = -11/10 or - 1 1/10.

I hope this helps!

The vertex of this parabola is at (2.-3). When the yvalue is -2, the xvalue is 5. What is the coefficient of the squared term in
tatiyna

Answer:

The coefficient of squared term is 1/9

Step-by-step explanation:

The vertex of parabola is (2.-3)

We know the vertex form of a standard parabola

y=a(x-h)^2+k,\text{ where (h,k) is vertex}

Plugging values of h and k, h= 2, k = -3

y=a(x-2)^2-3

Now, x=5, y=-2

-2=a(5-2)^2-3

-2=9a-3

9a=1

a=\frac{1}{9}

Thus, the coefficient of squared term is 1/9

MARCELLA LANDON WINS THIRD PRIZE IN THE CLEARINGHOUSE SWEEPSTAKES AND
Triss [41]

The amount of money in the account after 10 years is $278,814.10.

<h3>What will be the value of the account after 10 years?</h3>

The first step is to determine the amount she has left to invest.

Amount invested = amount won - amount spent on vacation

$250,000 - $10,000 = $240,000

The second step is to determine the future value of the account. The formula for calculating future value:

FV = P (1 + r)^nm

  • FV = Future value
  • P = Present value
  • R = interest rate = 1/5/12 = 0.125%
  • m = number of compounding =12
  • N = number of years

240,000 x 1.00125^(12 x10) = $278,814.10
