What is the rate of change between the interval x= pi and x= 3pi/2
Romashka [77]

Answer:

\frac{6}{\pi } or 1.9099

Step-by-step explanation:

Look for y values at each of those given values of "x" and apply the slope formula.  When x = pi. y = -1 so the coordinate is (\pi,-1).  When x = 3pi/2, y = 2 so the coordinate is (\frac{3\pi }{2},2)

Plug those values into the slope formula:

\frac{2-(-1)}{\frac{3\pi }{2}-\pi}

You need a common denominator of pi:

\frac{3}{\frac{3\pi-2\pi}{2} }=\frac{3}{\frac{\pi }{2} }

Do the math on that to get a slope of \frac{6}{\pi } =1.9099

Which of these are the intercepts of the graph of y=3x-12
lutik1710 [3]
<span>The equation of the linear function is given in the form of a directional
</span><span>equation consists of solid :
1.współczynniki a and b .
2. The variables x and y

</span>y=  3x - 12
y = ax + b 
a = 3      (<span>the slope of the tangent to the x-axis)
</span>b = - 12  (<span>intersection of the axis y)
</span>we look for the point ( 0 , -12 ) because b = -12

A. (4, 0) ,(0, -12)
B.(12 ,0), (0,4)
C.(3, 0), (0, 4)
D.(4, 0), (0, 3)
E.(-4, 0), (0, -12)

<span>fit and answers a,e

Cual es la factorizacion prima del 20​
Verizon [17]

Answer:

Sí, 2 • 10 = 20. Luego factoriza 10, que también es divisible entre 2 (2 • 5 = 10). Ambos factores son primos, por lo que puedes detenerte. La factorización prima de 20 es 2 • 2 • 5, la cual puedes escribir usando la notación exponencial como 22 • 5.

Step-by-step explanation:  

espero que esto ayude ;)
