Sum of two digit number is9.When we interchange the digits it is found that the resulting new number becomes twice the other num

ruslelena [56]

Answer:

4 and 5

Step-by-step explanation:

Let the numbers be x and y

If their sum is 9, hence;

x + y = 9 ....1

When reversed

10y+x = 2(10x+y)

10y+x = 20x + 2y

10y - 2y = 20x - x

8y = 19x

y = 10x/8 ...2

Substitute equation 2 into 1;

From 1;

x+y = 9

x +(10x/8) = 9

18x/8 = 9

18x = 72

x = 72/18

x = 4

Since x+y =9

y = 9-x

y =9-4

y = 5

Hence the numbers are 4 and 5

What are the exact solutions of x^2 = 5x + 2?

aleksandrvk [35]

Move everybody to one side
minus 5x+2 both sides
x^2-5x-2=0
use quadratic formula where
if you have
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

1x^2-5x-2=0
a=1
b=-5
c=-2

x= $\frac{-(-5)+/- \sqrt{(-5)^{2}-4(1)(-2)} }{2(1)}$
x= $\frac{5+/- \sqrt{25+8} }{2}$
x= $\frac{5+/- \sqrt{33} }{2}$

aprox
x=5.372281323 or -0.3722813233

cupoosta [38]

Answer:

$7821.74

Step-by-step explanation:

Eva invests $6400 in a new savings account which earns 3.4% annual interest, compounded continuously.

We have to find the value of her investment after 6 years,

Now, using the formula for the compound interest we can get the value of her investment.

So, it will be $V = 6400 (1 + \frac{3.4}{100} )^{6} = 7821.74$ Dollars (Approximate)
