The vertex for f(x)=(x+1)^2-2 would represent a minimum because the coefficient of the binomial (x+1) squared term is positive (understood to be in front of the parenthesis). Think about the Vertex From: y=a(x-h)^2+k where "a" is the coefficient of the binomial and(h, k) is the vertex. If "a" is positive the parabola opens up U (Making the vertex the lowest point of the graph). If "a" is negative the parabola opens down N (making the vertex the highest point of the graph)

Therefore:

The vertex of f(x) is a minimum because a=1.

The vertex of g(x) is a maximum because a=-1.

These equations are already in vertex form. So, we can easily find the vertex of each equation.

f(x) = -(x-1)^2 - 2

Vertex: (1,-2)

The vertex in this equation is the maximum because it faces down (a=-1).

g(x) = (x+2)^2 + 1

Vertex: (-2,1)

The vertex in this equation is the minimum because it faces up (a=1).

Tthe area of a circle increases at a rate of 5 cm^2/s.
abruzzese [7]

Answer:

(a) 0.198 cm/s (b) 1 cm/s

Step-by-step explanation:

It is given that,

The rate of change of area of a cicle, \dfrac{dA}{dt}=5\ cm^2/s

(a) The area of a circle is given by :

A=\pi r^2

Differentiate both sides,

\dfrac{dA}{dt}=2\pi r\dfrac{dr}{dt}\\\\\text{Put the value of dA/dt and r = 4 cm}\\\\\dfrac{dr}{dt}=\dfrac{dA/dt}{2\pi r}\\\\\dfrac{dr}{dt}=\dfrac{5}{2\pi \times 4}\\\\\dfrac{dr}{dt}=0.198\ cm/s

(b) Circumference, C=2\pi r = 5 cm

\dfrac{dA}{dt}=2\pi r\dfrac{dr}{dt}\\\\\dfrac{dr}{dt}=\dfrac{dA/dt}{2\pi r}\\\\\dfrac{dr}{dt}=\dfrac{5}{5}\\\\\dfrac{dr}{dt}=1\ cm/s

Hence,

(a) 0.198 cm/s (b) 1 cm/s

Match the type of sequence to the appropriate example
notsponge [240]

Step-by-step explanation:

1)

Considering the sequence

2, 9, 16, 23,...

This sequence is an arithmetic sequence as the common difference between consecutive terms is constant.

i.e. d = 9-2 = 7, d = 16-9 = 7, d = 23-16 = 7

2)

Considering the sequence

3, 15, 75, 375,...

This sequence is geometric sequence as the common ratio between consecutive terms is constant.

i.e. r = 15/3 = 5, r = 75/15 = 5

3)

Considering the sequence

0,4,4,8,...

This sequence is not in arithmetic sequence as the common difference is not same.

This sequence is also not in geometric sequence as the common ratio is not same.

As the 2nd and 3rd term is repeating, it means the next term i.e. 5th would be 8 as the 4th term is 8.

So, it will be a recursive sequence.

4)

y=(1.1)^{x}

As the base of this exponential function is greater than 1.

i.e. base>1 because 1.1 > 1.

Therefore, this function will have exponential growth.

5)

y=(\frac{1}{4})^{x}

As the base of this exponential function is less than 1. i.e. base because 1/4 < 1.

Therefore, this function will have exponential decay.

Keywords: exponential decay, exponential growth, arithmetic sequence, geometric sequence, recursive sequence
