A sequence is defined by the recursive formula f(n+1)=f(n)-2. If f(1)=18, what is f(5)?

N76 [4]

Answer:

$f(5)=10$

Step-by-step explanation:

A sequence is defined by the recursive formula $f(n+1)=f(n)-2$

If $f(1)=18,$ then

for $n=1: f(2)=f(1+1)=f(1)-2=18-2=16$

for $n=2: f(3)=f(2+1)=f(2)-2=16-2=14$

for $n=3: f(4)=f(3+1)=f(3)-2=14-2=12$

for $n=4: f(5)=f(4+1)=f(4)-2=12-2=10$

Values of k for which the quadratic equation 2x - kx + k 0 has equal roots is

WARRIOR [948]

Answer:

The answer is D.

Step-by-step explanation:

We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :

$D = {b}^{2} - 4ac$

$let \: D = 0 ,a = 2,b = k,c = k$

$0 = {k}^{2} - 4(2)(k)$

${k}^{2} - 8k = 0$

$k(k - 8) = 0$

$k = 0$

$k - 8 = 0$

$k = 8$

How do you find out the percentage of 55% of 140

qwelly [4]

I just found 10% of it, which is 14, then found 5% of it through the previous work, which is 7

then i multiplied 7 by 11, because 55/5 is 11, so 55% of 140 is 77
