Answer:

53092.92 square inches

Step-by-step explanation:

Surface Area of a Sphere = 4πr2

Radius = ½D = 130÷2 = 65

4 × 3.14 × 65² = 53092.92

If −5e^x^2 y=x and y(−5)=0, find y′(−5) by implicit differentiation

xenn [34]

Differentiate:
-5×2(xe^x^2)y-5e^x^2dy/dx=1
-5e^x^2(2xy+y´)=1
When x=-5, y=0:
-5e²⁵y´=1, so y´(-5)=-eˉ²⁵/5

Can someone please explain y=mx+b

lana [24]

$y=mx+b$ is slope-intercept form, which is a way of writing an equation for a line.

In this equation, $m$ represents the slope and $b$ represents the y-intercept.

$x$ and $y$ are the coordinates of a point on the resulting line.

Here are some examples:

$y=3x+2$

$y=-2x-4$

$y=8x-1$

$y=-7x+5$
