1.4565 x 10^4

1.905 x 10^7

Step-by-step explanation:

-Start with 2500-

1000 is 10^3.

so, 2.5 x 10^3 = 2500

Please right an equation that is perpendicular in slope intercept form <br> (3,-4); y=1/3x-5

kozerog [31]

Answer:

y=-3x+5

Step-by-step explanation:

So, with perpendicular equations, you flip the slope, so 1/3 becomes 3/1, and make it negative, and if it is already negative, you make it positive. So, since we have the slope, move on to the b=y-mx, so b=-4-(3)(-3), multiply to get b=-4-(-9), which makes our y-int 5.

Which function has a range of {y|y ≤ 5}? f(x) = (x – 4)2 5 f(x) = –(x – 4)2 5 f(x) = (x – 5)2 4 f(x) = –(x – 5)2 4

Lorico [155]

The function range of {y|y ≤ 5} is f(x)=-(x-4)^4+5.

Since the range has less than a sign, this means that the parabola is

facing downwards and it means that a is negative.

The range is given by

${y|y \leq k}$
