**Answer:-8.5714285714 × 10-1**

**Step-by-step explanation:**

**-101/119=-0.85714285714**

remember Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.

so -0.85714285714 in standard form is -8.5714285714 × 10-1

**Answer:**

4. dy/dx = -2

8. dy/dx = 1/2 x^(-3/2)

10/ dy/dr = 4 pi r^2

**Step-by-step explanation:**

4. y = -2x+7

dy/dx = -2(1)

dy/dx = -2

8. y = 4 - x^-1/2

dy/dx = - (-1/2x^ (-1/2-1)

dy/dx = 1/2 x^(-3/2)

10. y = 4/3 pi r^3

dy/dr = 4/3 pi (3r^2)

dy/dr = 4 pi r^2

If it's just **1.1 <= 1.21** then its deemed true

But since there's no identified **x** I'll list 2 possible solutions.

**1) 1.1x ≤ 1.21**

**Divide 1.1 from both sides.**

**x ≤ 1.1**

I don't know how to graph on a computer, sorry.

**2) 1.1 ≤ 1.21x**

**Divide 1.21 from both sides.**

**x ≥ 0.91 (Approx.)**

Again, don't know how to graph on a computer.
