The function p(x) = x(x - 5)(x − 2)(x+3) has four zeros. What is the smallest zero?
=
X =
1
1
2

X
3

Answers

Answer: The smallest zero is -3.

Step-by-step explanation: Zeros of a function are the values of input for which the function gives 0 output.

Here, the given function is,

p(x) = x(x-5)(x-2)(x+3)

For finding the zeroes of p(x),

p(x) = 0

⇒ x(x-5)(x-2)(x+3) = 0,

⇒ x = 0 or x - 5 = 0 or x-2=0 or x+3=0

⇒ x = 0 or x = 5 or x = 2 or x = -3

Thus, the zeros of the given function are 0, 5, 2, -3

In which -3 is smallest.

Answer:

x = -3

Step-by-step explanation:

x(x-5)(x-2)(x+3) = 0    means at least one of these terms = 0

so  

                        x = 0       or

x-5 = 0     then x = 5        or

x-2 = 0     then x = 2       or

x+3 = 0     then x= -3

f(x) is our regular graph where the y value is determined by the x value that is plugged in.

f(x + 2) = horizontal shift to the left 2 units

---x, the horizontal axis, is what is being altered here because the change occurs within the parenthesis. We always do the opposite action/move the opposite way when the shift occurs within the parenthesis.

f(x) + 2 = vertical shift up 2 units

---y, the horizontal axis, is what is being altered here because the change occurs outside the parenthesis. We move the function as we would expect to when the shift occurs outside the parenthesis.

Select all ordered paris that satisfy the function,

y = -3x + 9

A. (-2, 15)
B. (1, -6)
C. (3, 0)
D. (6, 1)

Answers

Answer:

(-2,15) (3,0)

Step-by-step explanation:

By substituting the x value in the coordinate (the first number in the bracket) and solving the equation, you must get the y value in the coordinate (second number in the bracket.

So that is to say:

A

y= -3x + 9

y = -3(-2) + 9

y = 6 + 9

y= 15

Also note that B is not one of them, because the y value you get when you substitute the x value in the equation is NOT NEGATIVE 6.

E
D

A 1
B 11
C 14
D 9

Answers

The length of the segment DF is 11 units

How to determine the length of DF?

The given parameters are:

ED = 2y + 12

DF = 3y + 8

EF = 25

The length EF is:

EF =ED + DF

This gives

2y + 12 + 3y + 8 = 25

Evaluate the like terms

5y + 20 = 25

Subtract 20 from both sides

5y = 5

Divide by 5

y = 1

Substitute y = 1 in DF = 3y + 8

DF = 3(1) + 8

Evaluate

DF = 11

Hence, the length of DF is 11 units

2. is this given figure on the side a parallelogram of Not?(prove using the properties of parallelogram)​

Answers

The value of the x and y is 12 and -10 respectively, and the provided figure is a parallelogram because the diagonals bisect each other.

What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

As we know in the parallelogram, the diagonals bisect each other.

Then,

432 = 3x²

x² = 144

x = √144

x = 12

In the parallelogram, the adjacent opposite angles are the same.

∠C+∠B = 240°

= 360 - 240

∠A + ∠D = 120°

∠A = ∠D = 120°/2 = 60

∠D/2 = 60/2 = 3y + 60

3y + 60 = 30

3y = -30

y = -10

From the definition of the parallelogram, the provided figure is a parallelogram.

Thus, the value of the x and y is 12 and -10 respectively and the provided figure is a parallelogram because the diagonals bisect each other.

What is of volume of cylinder?

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

The volume of the cylinder can be given as,

V=(πd^2h)4

Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.

The height of tank is 30 inches and the length of the diameter of the base is 27.5 inches. Thus, the volume of it is,

V=[π(27.5)²(30)] /4

V=17818.72 cubic inches.

One us gallon is equal to approximately 231 cubic inches. Thus, the volume in gallon is,

V=17818.72/231

V=77.12 gallons.

A good rule of thumb is to have about 3 inches of fish per 2 gallons of water. The number of 6 inches cichlids the can put in 77.12 gallons tank is,

V=(77.12 x 3)/(6 x 2)

V=19.28

Thus, the maximum number of African cichlids which can put by Chiletso  in this cylindrical fish tank is 19.

A particular tree falls over in a bonsai forest and is considered to be an average tree (in the middle 20%). If the mean height is 10cm and the standard deviation is 2 between what heights must the tree be?

Answers

Using the normal distribution, it is found that the tree must have heights between 9.49 cm and 10.51 cm.

Normal Probability Distribution

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

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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.

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 10, \sigma = 2[/tex]

Considering the symmetry of the normal distribution, the middle 20% is between the 40th percentile(Z = -0.253) and the 60th percentile(Z = 0.253), hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.253 = \frac{X - 10}{2}[/tex]

X - 10 = -0.253 x 2

X = 9.49.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.253 = \frac{X - 10}{2}[/tex]

X - 10 = 0.253 x 2

X = 10.51.

A surface on which one end or side is at a higher level than another; a rising or falling surface.

The slope of the line tangent to the polar curve;

[tex]\rm r =3sin\theta[/tex]

Step-by-step explanation:

they are counting by 2s      10,12,14,16,18

Hope this helps!

Answer:

18

Step-by-step explanation:

It seems like for this pattern, as the x-value(base value) increases, the corresponding y-value(value changing with the base value) increases by 2 given that the function starts with a y-intercept of 8. So at the value 0, the corresponding number would be 8. So in this case, by creating a function regrading this information we can solve for the corresoponding value of 5: y = 2x + 8

y = 2 * 5 + 8

y = 10 + 8

y = 18

5 = 18

Another way to approach this is just by following the pattern given to us in the description. We see that the pattern starts at 10, and increases by 2 for each increasing base value. Therefore, if 4 = 16, then 16 + 2 = 5, so 5 = 18.

What is the radius of a sphere with a volume of 47270 cm 3 , 47270 cm 3 , to the nearest tenth of a centimeter?

Answers

Mark brainalist if this helped thanks

The volume of a sphere is 47270 cm ^3 to find the radius of the sphere .

We know that the formula of the volume of the sphere is given by volume =4/3 pie r ^3
Where r is the radius of the sphere

Substitute the value to get r , and we get
47270=4/3 x 22/7 x r^3

Transpose the equation, and we get
r^3=47270 x 3/4 x 7/22
r^3 =23635 x 3/2 x 7/22

On further solving , we get
r^3 =496335/44
r^3 =11280.34091
r= 3 cube root 11280.34091
r=22.4271
So the radius of the sphere is 224271 cm
And on rounding it off to the nearest tenth of a centimeter , the radius of the sphere becomes 22.4 cm
So the answer is 22.4 cm
