Answer:

1.87500

Step-by-step explanation:

Given:

The function is

[tex]f(x)=(x+3)^2(x-5)^6[/tex]

To find:

The zeros of the given function.

Solution:

The general form of polynomial is

[tex]P(x)=a(x-c_1)^{m_1}(x-c_2)^{m_2}...(x-c_n)^{m_n}[/tex]       ...(i)

where, a is a constant, [tex]c_1,c_2,...,c_n[/tex] are zeros of respective multiplicities [tex]m_1,m_2,...,m_n[/tex].

We have,

[tex]f(x)=(x+3)^2(x-5)^6[/tex]

On comparing this with (i), we get

[tex]c_1=-3,m_1=2[/tex]

[tex]c_2=5,m_2=6[/tex]

It means, -3 is a zero with multiplicity 2 and 5 is a zero with multiplicity 6.

Therefore, the correct option is B.

Step-by-step explanation:

because we can also find out the value of x in second equation like this

3x=21

x=21/3

x=7

Answer:

We conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.

Step-by-step explanation:

Given the first equation

solving the equation

3x-5 = 16

adding 5 to both sides

3x-5+5 = 16+5

3x = 21        ∵ 3x = 21 is the 2nd equation      

divide bothe sides by 3

3x/3 = 21/3

x = 7

Please notice that when simplifying 3x-5 = 16, the moment we reach 3x=21, we can determine that it represents the same equation.

In other words, whatever the value of x we will get, it will satisfy both equations.

Therefore, we conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.

Verification:

Consider the 2nd equation

3x = 21

Put x = 7

3(7) = 21

21 = 21

Thus, it has been validated that when we conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.

Answer:

Cost = Rs. 6095.95

Step-by-step explanation:

We are given the perimeter as 440m.

Mow,perimeter of a circle is also called circumference.

Formula for circumference of a circle is;

C = 2πR

Thus:

2πR = 440

R = 440/2π

R = 70 m

We are told that A path 1.4m runs inside the park. Thus radius of smaller circle: r = 70 - 1.4 = 68.6 m

Area of larger circle: A1 = πR² = π(70²)

A1 = 4900π

Area of smaller circle: A2 = πr² = π(68.6²)

A2 = 4705.96π

Area of path = A1 - A2

Area of path = 4900π - 4705.96π

Area of path = 194.04π Sq.m

We want to find the cost of gravelling the path at the rate of Rs.100 per square meter.

Thus;

Cost = 100 × 194.04π

Cost = Rs. 6095.95

Answer:

[tex]75^{\circ}\text{F}[/tex]

Step-by-step explanation:

Last Wednesday it was 90 degrees Fahrenheit.

Today it is 15 degrees Fahrenheit colder than it was last Wednesday.

So, today's temperature will be the difference of the temperatures of last Wednesday's and today's temperature. We have to find the difference as it is colder today means it is a lower temperature than last Wednesday's.

[tex]90-15=75^{\circ}\text{F}[/tex]

Today's temperature is [tex]75^{\circ}\text{F}[/tex]

Answer:

they give you two points... so use the point slope formula with one on the points

y - y1 = m ( x - x1)

Step-by-step explanation:

find the slope m  

m = y2 -y1 / x2-x1

from the given.. x1=2  and y1 = -5

x2 = 3  and y2 = -1     then,

m = -1 -( -5) / 3 - 2

m = 4/1

m = 4

now plug in to the point slope formula  either of the points... I'll use the 1st point

y - 2 = 4(x -(-5))

y -2 = 4(x +5)

y -2 = 4x +20

y = 4x +22

Answer:

10.5 Inches of snow after 6 hours

Step-by-step explanation:

First you would divide

7/4=1.75

Then you would multiply by 6

1.75*6=10.5

10.5 inches of snow would be the total

Hope this helped! :D

The amount of snowfall in 6 hours, if the amount of snowfall is directly proportional to the time, is 10.5 inches.

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.

Given:

In a winter storm, the amount of snowfall is directly proportional to the time,

After 4 hours, a total of 7 inches of snow had fallen,

Calculate the amount of snowfall in one hour as shown below,

amount of snowfall in one hour  =  7 / 4

Calculate the amount of snowfall that occurs in 6 hours,

Amount of snowfall in 6 hours  =  7 / 4 × 6

Amount of snowfall in 6 hours  =  10.5 inches

Answer:

The height of the mother is 147.25cm

Step-by-step explanation:

The height of the new-born panda is 15.5 centimeters.

Let the height of the mother be = x

We know from the problem that the mother is 9.5 times taller than the baby.

We can get the height of the mother by multiplying the height of the baby by 9.5.

i.e x = 9.5 X 15.5 = 147.25cm

Step-by-step explanation:

well I don't know what the answer choices are but here's some information that could help.

all of the angles in a triangle have to add up to 180°

and isosceles triangles have at least two sides that are congruent. This also means that at least two angles have to be congruent

based on this there could be two angles that measure 50° and the last angle would measure 80°

or one angle could measure 50° and the other two angles each measure 65 degrees

Answer:

(x,y)=(-1,1)

Step-by-step explanation:

Given that,

3x + 5y = 2   .....(1)

6x - 10y = -16  ....(2)

Finding the value of x from equation (1).

[tex]x=\dfrac{2-5y}{3}[/tex]

Put the value of x in equation (2)

[tex]6(\dfrac{2-5y}{3}) - 10y = -16\\\\2(2-5y)-10y=-16\\\\4-10y-10y=-16\\\\-20y=-16-4\\\\y=1[/tex]

Put the value of y in equation (1) :

[tex]3x + 5(1) = 2\\\\3x=2-5\\\\3x=-3\\\\x=-1[/tex]

So, the solution of the equations is (-1,1).

Part (a)

Work Shown:

[tex]3\left(\frac{x}{7}+2\right) = 6\\\\\frac{x}{7}+2 = \frac{6}{3}\\\\\frac{x}{7}+2 = 2\\\\\frac{x}{7} = 2-2\\\\\frac{x}{7} = 0\\\\x = 7*0\\\\x = 0\\\\[/tex]

In step 2, I divided both sides by 3. In step 4, I subtracted 2 from both sides. In step 6, I multiplied both sides by 7.

[tex]2\left(\frac{5x}{3}-1\right) = 8\\\\\frac{5x}{3}-1 = \frac{8}{2}\\\\\frac{5x}{3}-1 = 4\\\\\frac{5x}{3} = 4+1\\\\\frac{5x}{3} = 5\\\\5x = 3*5\\\\5x = 15\\\\x = \frac{15}{5}\\\\x = 3\\\\[/tex]
