In any given week, salesman A earns $65 per sale, so his paycheck amounts to $p_A(s)=65s$ (where $0\le s\le20$ ).

Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns $p_B(s)=45s+300$ .

Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is $p_C(s)=900$ .

Find the x- intercept and y- intercept of a straight line 6x+5y=30

EleoNora [17]

Answer:

x-intercept = 30/6 = 5

y-intercept = 30/5 = 6/1 = 6.00000

Step-by-step explanation:

calculate the Y-intercept:

Notice that when x = 0 the value of y is 6/1 so this line "cuts" the y axis at y=6.00000

y-intercept = 30/5 = 6/1 = 6.00000

Calculate the X-Intercept :

When y = 0 the value of x is 5/1 Our line therefore "cuts" the x axis at x= 5.00000

x-intercept = 30/6 = 5

Find all points on the curve that have the given slope.x = 2cost, y= 8sint, slope =-1

tatuchka [14]

Answer:

$t_{1} = 0.422\pi \pm \pi\cdot i$ , $\forall \,i \in \mathbb{N}_{O}$

$t_{2} = 1.422\pi \pm \pi\cdot i$ , $\forall \,i \in \mathbb{N}_{O}$

Step-by-step explanation:

In the case of parametric equations, the slope of the curve is equal to:

$\frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

Where $\frac{dx}{dt}$ and $\frac{dy}{dt}$ are the first derivatives of $x$ and $y$ regarding $t$ . Let be $x(t) =2\cdot \cos t$ and $y(t) = 8\cdot \sin t$ , their first derivatives are found:
