for what values of a, b and c is f(x)=ax square + bx + c a constant, a linear or a quadratic equation?​

Answer:

\(y=|x-(-2)|+2\)

Step-by-step explanation:

Hope this is helpful.

The required absolute function is given as y = |x - 2| + 2.

Given that,
From the graph, y = |x - h| + k, values of h and k is to be determined,

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
In the graph and function, h represents the shift on the x-axis, which 2 units left so the value of h is 2, while k is given the shift of the function over the y-axis which 2 units up means that k = 2

Thus, The required absolute function is given as y = |x - 2| + 2.

y = ((10/4)x) - 1

Answer:

{x,y} = {25/9,23/9}

Step-by-step explanation:

// Solve equation [2] for the variable  x  

 [2]    x = -4y + 13

// Plug this in for variable  x  in equation [1]

  [1]    5•(-4y+13) + 2y = 19

  [1]     - 18y = -46

// Solve equation [1] for the variable  y  

  [1]    18y = 46  

  [1]    y = 23/9  

// By now we know this much :

   x = -4y+13

   y = 23/9

// Use the  y  value to solve for  x

Answer:

Four percent

Step-by-step explanation:

(a) The distribution of x is  x ~ N\((33, 10^2)\)

(b)  The probability that the percent of fat calories a person consumes is more than 6 is  P(z > - 2.7)

The lower quartile is the point that separates the lower 25% of the data from the rest. While the upper quartile separates the lower 75% (or upper 25%) from the rest of the data. The lower and upper quartiles are respectively known as the first and third quartiles.

Calories that a person each day is normally distributed.

Population mean, μ = 33

Population standard deviation, σ = 10

If "x" represent the percent of fat calories then the z - scores for "x" can be given as:

z = x - μ / σ

(a) The distribution of "x" will be normal with the mean equal to 33 and standard deviation equal to 10. It can be written as x ~ N\((33, 10^2)\)

(b) The probability that the percent of fat calories a person consumes is more than 6:

P(x > 6) = P \((z > \frac{6 - 33}{10} )\\\)

            = P(z > - 2.7)

The rate of change is $2.33 per visitor

Rate of change refers to how quickly something changes over time. For example, acceleration is the rate of change of velocity with time.

Velocity is also the rate of change in position with time.

Rate of change means difference or changes with time.

It cost $31 for 3 visitor. This means that the cost per visitor is $31/3 = $10.33

It cost $80 for 10 visitor. This means that the cost for one visitor is 80/10 = $8

The rate of change is the difference in rate. This means that rate of change = $10.33 - $8

= $2.33/visitor

Step-by-step explanation:

The minimum wage set by the government at $7.50 per hour does not result in a pay cut for unskilled workers, as it is below the equilibrium wage of $8.00 per hour.

The wage rate remains unchanged, and the labor market remains in balance.

The statement is false.

False.

The equilibrium wage in the market for unskilled labor is $8.00 per hour, which means that the market naturally sets the wage rate at this level, based on the forces of supply and demand.

The government then sets a minimum wage at $7.50 per hour.

Since the minimum wage is below the equilibrium wage, it does not directly impact the wage rate for unskilled workers.
The equilibrium wage represents the point at which the supply of labor (the number of workers willing to work at a given wage) equals the demand for labor (the number of workers that employers are willing to hire at a given wage).

In this case, both workers and employers are satisfied with the $8.00 per hour wage, and the labor market is balanced.
The government sets a minimum wage below the equilibrium wage, it essentially sets a wage floor that is not binding. Employers are still willing to pay the equilibrium wage of $8.00 per hour, and workers are still willing to accept this wage.

The wage for unskilled workers remains at $8.00 per hour, and there is no pay cut of 50 cents per hour.

Answer:70%

Step-by-step explanation:

A sample size of 1024 is needed so that a 90% confidence interval will specify the mean to within ±0.5.

The margin of error for a confidence interval is calculated using the following formula:

ME = z * SE

where:

ME is the margin of error

z is the z-score for the desired confidence level

SE is the standard error of the mean

In this case, we want the margin of error to be 0.5, and the confidence level is 90%. The z-score for a 90% confidence interval is 1.645. The standard error of the mean is calculated using the following formula:

SE = σ / √n

where:

σ is the population standard deviation

n is the sample size

We are not given the population standard deviation, so we will assume it is known and equal to 1. This is a conservative assumption, as it will result in a larger sample size being required.

Plugging in the values for ME, z, and σ, we get the following equation for n:

0.5 = 1.645 * 1 / √n

Solving for n, we get the following:

n = (1.645 * 1)^2 / 0.5^2 = 1024

Therefore, a sample size of 1024 is needed so that a 90% confidence interval will specify the mean to within ±0.5.

Step-by-step explanation:

The radius of the circle = RO=MO (since NA=PA). Therefore PO=1/2 MO=1/2*10=5 ft

Given that,NA = PA and MO ⊥ NA, RO ⊥ PA and MO = 10 ft. 5 ft. 10 ft.Since MO ⊥ NA and RO ⊥ PA,

Therefore MO and RO are the heights of ∆NMA and ∆PRA respectively.And, NA = PA => ∆NMA ≅ ∆PRA

Therefore, AM = AR ...(1)Also, from the question,

MO = 10 ft.

=> Area of ∆NMA = (1/2) * NA * MO = (1/2) * NA * 10 ft. = 5NA ...(2)Similarly, RO = 10 ft.

=> Area of ∆PRA = (1/2) * PA * RO = (1/2) * PA * 10 ft. = 5PA ...(3)Now, from (1), AM = ARAnd, from (2) and (3), 5NA = 5PA

=> NA = PAAnd, AM = AR => 2AM = NA + PA = 2NA => AM = NA = 10 ft.

OA = ON + NA = 10 + 10 = 20 ft. Hence, the answer is 5fts

Step-by-step explanation:

The expression \(-2\vec C+6\vec D\) in the ordered pair notation is (16,-16).

The vector components of a vector are represented as the ordered pair of its x and y components.

For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is \(a \vec i+b \vec j\).

Now the vector C has its x- component = -2

y- component of C = -1

Therefore, ordered pair notation of C = (-2, -1)

x- component of D = 2

y-component of D = -3

Therefore, ordered pair notation of D = (2,-3)

So the expression  \(-2\vec C+6\vec D\) = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

= (16, -16)  in the ordered pair notation.

Answer:

84°

Step-by-step explanation:

angles in a quadrilateral add to 360°. 360-(114+76)=5x =170°. 170°/5 = 32°. x=32°

angles on a straight line add to 180°.

2x = 64°. 180-64=116°. y=116°.

y-x = 116-32 = 84°

Answer:

\(78\)

Step-by-step explanation:

The inner angles of a quadrilateral all add up to 360. This means we can write the following

\(114 + 76 + 3x + 2x = 360\\190 + 5x = 360\\5x = 170\\x = 34\)

Now that we have x we can find y. Notice that y and 2x are on the same line. Any line cutting another straight line will create two angles that add up to 180.

Therefore we can write

\(2x + y = 180\\2(34) + y = 180\\y = 112\)

Finally computing y - x

\(y - x = 112 - 34 = 78\)

A woman has invested $20 000 as a fixed deposit in a bank for 3 years. The interest rate is 5% per annum, calculated on a yearly basis. The woman needs to find the compound interest received for the period of 3 years.

Principal (P) = $20 000, Rate of Interest (R) = 5%, Time period (t) = 3 years, and compound interest.

We know that the compound interest is calculated as: Compound Interest (CI) = P [(1 + R/100) t - 1]

Using the given values, we have: CI = $20 000 [(1 + 5/100)3 - 1]CI = $20 000 [(1.05)3 - 1]CI = $20 000 [1.157625 - 1]CI = $20 000 [0.157625]CI = $3,152.5

Answer:

\(w=-1/5\text{ or } 3\)

Step-by-step explanation:

We have the equation:

\(-2|5w-7|+9=-7\)

Let's first isolate the absolute value. Subtract 9 from both sides:

\(-2|5w-7|=-16\)

Divide both sides by -2:

\(|5w-7|=8\)

Now, we can split them into two cases. By the definition of absolute value:

\(5w-7=8\text{ or } -(5w-7)=8\)

Let's do each case individually.

Case 1:

We have:

\(5w-7=8\)

Add 7 to both sides:

\(5w=15\)

Divide both sides by 5:

\(w=3\)

Case 2:

We have:

\(-(5w-7)=8\)

Divide both sides by -1:

\(5w-7=-8\)

Add 7 to both sides:

\(5w=-1\)

Divide both sides by 5:

\(w=-1/5\)

So, our answers are:

\(w=-1/5\text{ or } 3\)
