Answer:

Slope: -1.4

y = -1.4x - 0.49

Step-by-step explanation:

Slope: dy/dx = 2x

x = -0.7

dy/dx = -1.4

Equation of tangent:

y = mx + c

y = -1.4x + c

When x = -0.7, y = 0.49

0.49 = (-1.4)(-0.7) + c

c = -0.49

y = -1.4x - 0.49

If A and B are nonzero integers with the same signs is the product negative or postitive
melisa1 [442]
Remember.

positive number x positive number = positive number
positive number x negative number = negative number
negative number x positive number = negative number
negative number x negative number = positive number

So if both numbers have the same sign, either both positive or both negative, then the product will be positive.

navik [9.2K]

Answer:

22.6 inches

Step-by-step explanation:

The circumference of a circle is given by

C = pi *d

The diameter is 7.2 inches

Approximating pi by 3.14

C = 3.14 * 7.2

C = 22.608

Rounding to the nearest tenth

C = 22.6
