Write the equation of the graph in factored form. remember to include the y or f(x)

Answer:

b because it just is

Step-by-step explanation:

Answer:  19 people will be represented by an angle 152 degrees.

Step-by-step explanation:

Set up a  proportional relationship to solve for this

[tex]\frac{360}{152} = \frac{45}{y}[/tex]        Cross multiply

360y = 6840   Divide both sides by 360

y =  19

Answer:

change the expression to y

Step-by-step explanation:

[tex]x + 3y = 9[/tex]

[tex]3y = - x + 9[/tex]

[tex]y = \frac{ - 1}{3} x + \frac{9}{3} [/tex]

the gradient is the coefficient of x,

[tex] - \frac{1}{3} [/tex]

3.2d

4. 68x³

9514 1404 393

Answer:

Step-by-step explanation:

Factoring out the greatest common factor in each case, we can simplify the process of finding the non-zero solution. The solutions are the values of the variable that make the factors be zero.

1) 7x^2 +2x = 0 = (x)(7x +2)   ⇒   x = 0; x = -2/7

__

2) 5b^2 -10b = 0 = (5b)(b -2)   ⇒   b = 0; b = 2

__

3) 3d^2 -d = 0 = d(3d -1)   ⇒   d = 0; d = 1/3

__

4) 17x^2 +51x = 0 = 17x(x +3)   ⇒   x = 0; x = -3

Answer:

[tex]x>-11[/tex]

Step-by-step explanation:

[tex]10+2x>-12[/tex]

Subtract both sides by 10

[tex]10+2x-10>-12-10\\2x>-22[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}>\frac{-22}{2} \\x>-11[/tex]

Answer:

Step-by-step explanation:

100 = -16t^2 + 92t

16t^2-92t + 100 = 0

4t^2 - 23t + 25 = 0

t = [23 ±√(23^2-4(4)(25))]/[2(8)] ≈ 1.5, 4.3

The rocket has altitude of 100 ft at 1.5 sec and 4.3 sec.

:::::

0 = 16t^2-92t = t(16t-92)

t = 0, 5.75

Rocket is in the air for 5.75 seconds

Answer: 62.4$

Step-by-step explanation: 20% of 52 is 10.4

Answer:

55%

Step-by-step explanation:

1/4 - Micah will only have a 25% chance of selecting a blue pencil.

1/5 - Micah will only have a 20% chance of selecting a red pencil.

Answer:

1/3

Step-by-step explanation:

2/6

1/3

Answer:

Probability of any one face to turn up is 1/6,

The probability of any above 3 is 3/6,

The probability of even number is also 3/6

So the probability of either above three or even outcome is 1/6(3/6 + 3/6)=1/6, since both events are independent of the any face event and both events are mutually exclusive.

NB:If the two events are not mutually exclusive, then

P(A) is the total event, P(B) the probability of any face above 3 and P(C) probability of any face an even number, then the Bayesian prediction formula is P(B|C) the probability of the event B occuring while C occurs is equal to (PC|P(B))/(P(B)+P(C), where P(C|B) is probability of C occuring at B.

So P(B|C)=(1/3 * 1/3)/(1/3 + 1/3) =(1/9)/(2/3) = 3/18= 1/6.

Answer:

Y = -1/2x + 7/2

Step-by-step explanation:

slope = -1/2

Answer:

Step-by-step explanation:

outer area=

first need to find the circumference of outer diameter

= π×4.8

= 15.079644.... cm

to find the outer curved area you would then do

= 77×15.079644

(ii) =1161.13264 cm²

inner curve area

circumference= π×4

=12.5663706.... cm

77×12.5663706

(i) =967.610537 cm²

total surface area=

as the outer and inner curved areas are already found only the top and bottom surfaces need to be

= area of larger circle

=π×4.8²

=72.382294.... cm²

smaller circle

=π×4²

=50.2654824.... cm²

72.382...-50.265

=22.1168116 x 2

=44.2336232 cm²

total surface area

(iii)= 2172.9768 cm²

(round this to however many decimals you need)

I hope this is understandable and useful!

Answer:

14. She deposited $15.50 into her bank.

15. The width would be 900.

Step-by-step explanation:

14. 245.60 + x = 261.10

x = 15.50

245.60 + 15.50 = 261.10.

She deposited $15.50 into her bank and resulted in her new bank balance appearing as $261.10.

15. Width is 900 cm

Length is 12 cm.

A = L X W = 108

A = L * 3/4L

108 = 3/4L2

Divide both sides by 3/4: multiply both sides by the inverse of 3/4 or 4/3.  

(4/3)*108 = L2

144 = L2

√144 = L

12 = L

W = 3/4*12

W = 9

Before we finish:

A = 108 = 9 x 12 = 108

W/L = 3/4 = 9/12 = 3/4

The width of the rectangle would be 3/4.

Step-by-step explanation:

y = 4x+3

2x-3y = 21

2x -3(4x+3) = 21

2x -12x -9 = 21

-10x = 21 + 9

-10x = 30

x = -3

Answer:

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

There are various types of sampling used by researchers and these are;

1. Random sampling.

2. Systematic sampling.

3. Stratified sampling.

4. Cluster sampling.

5. Opportunity or convenience sampling.

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.

For example, John a psychologist standing on the street requesting that passersby join in his research study.

Answer:

We conclude that the solution is:

Step-by-step explanation:

Given the equation

[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]

Expand 12(x + 8):  12x + 96

[tex]12x+96=11x-5[/tex]

Subtract 96 from both sides

[tex]12x+96-96=11x-5-96[/tex]

Simplify

[tex]12x=11x-101[/tex]

Subtract 11x from both sides

[tex]12x-11x=11x-101-11x[/tex]

Simplify

[tex]x=-101[/tex]

Therefore, we conclude that the solution is:

Answer:

8

Step-by-step explanation:

78 - 6 = 72 (Since the number falls short by six)

72 ÷ 9 = 8 (Number times 9 that equals 72)

Expert Answer:

Since the numbers are in the ratio 3:4 then let the numbers be 3x and 4x.

Thus the H.C.F. of the two numbers = x.

But the H.C.F is given as 4.

So, x = 4.

So, the numbers are,I

3x = 3 x 4 =12

And

4x = 4 x 4 = 16

We know,

H.C.F x L.C.M = Product of the two numbers

4 x L.C.M = 12 x 16

L.C.M = 48

Thus, the L.C.M of 12 and 16 , 48
