Step-by-step explanation: Add them all to get 3 3/4. subtract that from 4 1/2.
Answer:
$3743.43
Step-by-step explanation:
The amount is given by the formula ...
A = Pe^(rt)
where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...
A = $1600·e^(0.0425·20) = $1600·e^0.85
≈ $1600·2.33964685 ≈ $3743.43
The amount in the account will be $3743.43.
Answer:
<h3>explicit formula- a(n)=6+4(n-1)</h3><h3>recursive formula- a(n)=a(n)-1 +4; a(1)=6</h3>
Step-by-step explanation:
The roots are 1 +√7 and 1 -√7.
<h3>What is Quadratic equation?</h3>
A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0
Given equation:
y= x²+2x-6
First,
Half the coefficient of x and add and subtract the square of (b/2)
y= x²+2x-6+(1)²-(1)²
y= x²+2x+(1)² -6 -(1)²
y= (x+1)² -7
Now, equate y=0
(x+1)² -7 =0
(x+1)² = 7
x+1= ±√7
x=1 ±√7
Hence, the roots are 1 +√7 and 1 -√7.
