Since the sales price is 65%, the amount you save would be 35%. 35% of $25 is $8.75.

Find the minimum or maximum of the function. Describe the domain/range in interval notation y=6x^2-1
Margarita [4]

max is at vertex

in form y=ax^2+bx+c

the x value of the vertex is \frac{-b}{2a}

given, y=6x^2-1

a=6, b=0

the x value of the vertex is -0/(2*6)=0

the y value is y=6(0)^2-1=0-1=-1

so vertex is at (0,-1)

since the value of a is positive, the parabola opens up and the vertex is a minimum value of the function

therefore that value is the smallest value the function can be



domain=numbesr you can use for x

range=numbesr you get out of inputting the domain


domain=all real numbers

range is {y | y≥-1} since y=-1 is the minimum

\sum\limits_{k=1}^{\infty}420\left(\dfrac{1}{6}\right)^{k-1}

The infinite geometric series is converges if |r| < 1.

We have r=1/6 < 1, therefore our infinite geometric series is converges.

The sum S of an infinite geometric series with |r| < 1 is given by the formula :

S=\dfrac{a_1}{1-r}

We have:

a_1=420\left(\dfrac{1}{6}\right)^{1-1}=420\left(\dfrac{1}{6}\right)^0=420\\\\r=\dfrac{1}{6}

substitute:

S=\dfrac{420}{1-\frac{1}{6}}=\dfrac{420}{\frac{5}{6}}=420\cdot\dfrac{6}{5}=84\cdot6=504

Answer: d. Converges, 504.

B(n)=1 (-2)^n-1<br> What is the 4th term in the sequence
Vera_Pavlovna [14]

Answer:

The 4th term in the sequence is -8.

Step-by-step explanation:

The nth term of the sequence B is given by:

B(n) = (-2)^{n-1}

So the fourth term will be given by:

B when n = 4, that is, B(4).

B(4) = (-2)^{4-1} = (-2)^{3} = -8

The 4th term in the sequence is -8.
