The illustration below is a graph of the polynomial function P(x). The graph crosses the x-axis 2 times and touches the x-axis o

nce at the point (4, 0).
Part A: Use the key features of the graph to explain that the degree of the polynomial cannot be odd.

Part B: How many unique zeros does this polynomial have?

The polynomial graph crosses the x-axis at two points and touches x-axis at one point. It indicates the graph has four roots:

x=-1.5
x=-2
x=4
x=4

The last two roots have equal value as the graph touches the x-axis (not crosses it)

The graph has three unique roots

Determine the area under the standard normal curve that lies to the left of (a) Z=081. (b) Z=0.43. (c) Z= -0.33. and (d) Z= 1.04
nasty-shy [4]

Using the normal distribution, the areas to the left are given as follows:

a) 0.7910.

b) 0.6664.

c) 0.3707.

d) 0.8508.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X, and is also the area to the left of Z.

Hence:

  • The area to the left of Z = 0.81 is of 0.7910.
  • The area to the left of Z = 0.43 is of 0.6664.
  • The area to the left of Z = -0.33 is of 0.3707.
  • The area to the left of Z = 1.04 is of 0.8508.

Anybody know the answer ?
algol [13]
C=2πr
 We have 3/4 of circumference
 (3π/2)*2π=3/4.
 and it is equal 5π/2.
(3/4)*C=(3/4)*2πr
5π/2 = 6πr/4
5/2=6r/4
r=(5/2)*(4/6)=(5*4)/(2*6)=5/3
r=5/3
