Answer:

y = 4x + 3 is in what is called "slope-intercept" form or "y=mx+b" form which is the easiest form for graphing. The "3" is called the "y-intercept" and is where the line crosses the y axis.

The answer for your question is :

y = 4x + 3 is in what is called "slope - intercept" form or "y = mx + b" form which is the easiest form for graphing. The "3" is called the "y intercept" and is where the line crosses the y axis.

Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (4, −5, 2) and parallel

Nataliya [291]

Answer:

Step-by-step explanation:

From the given information, the symmetric equations for the line pass through(4, -5, 2) i.e ( $x_o, y_o, z_o$ ) and are parallel to $\dfrac{x+5}{1} = \dfrac{y}{2}= \dfrac{z-3}{1}$

The parallel vector to the line i + zj+k = ai + bj + ck

Hence, the equation for the line is :

$x = x_o + at \\ \\ x = y_o + bt \\ \\ x = z_o + ct$

x = 4 + t

y = -5 + 2t

z = 2 + t

Thus, x, y, z = ( 4+t, -5+2t, 2+t )

The symmetric equation can now be as follows:

$\begin {vmatrix} x = 4+ t \\ \\ \dfrac{x-4}{1} = t \begin {vmatirx} \end {vmatrix}$ $\begin {vmatrix} y = - 5+2t \\ \\ \dfrac{y+5}{2} =t \end {vmatrix}$ $\begin {vmatrix} z =2+t \\ \\ \dfrac{z-2}{1} =t \end {vmatrix}$

∴

$\dfrac{x-4}{1}= \dfrac{y+5}{2}=\dfrac{z-2}{1}$

The owner of a large restaurant is considering a new “no tipping” policy and wants to survey a sample of employees. The policy w

Stolb23 [73]

A) The strata to be used in this survey by the employer is; Type of Staff

B) Stratified Random Sampling will be preferred because the opinions of the staffs on the tipping policy may be the same within each type but differ across the different types of staffs.

A stratified random sampling is a type of sampling that divides a population into groups known as strata.

Now, from the question, we see that after adding a 20% to the cost of food and beverages, that the additional revenue will be distributed equally among the kitchen and server staffs.

This means the strata here will be the type of staff because the opinions of the staffs on the tipping policy may be the within each type but differ across both types of staffs.

Without using a calculator determine the number of real zeros of the function f(x) = x^3 + 4x^2 + x -6

hodyreva [135]

Try this:
x³+4x²+x-6=0
1) To re-write the equation into form:
1*x³+4*x²+1*x-6=0, the note 1+4+1=6, it means x=1
2) to re-write the equation into form:
(x-1)(x²+5x+6)=0
(x-1)(x+2)(x+3)=0
3)
$\left[\begin{array}{ccc}x-1=0\\x+2=0\\x+3=0\end{array}\right \ \ \textless \ =\ \textgreater \ \left[\begin{array}{ccc}x=1\\x=-2\\x=-3\end{array}\right$
Answer: -3;-2;1.
