dolphi86 [110]
Part a:-

7.15 rands = 1 dollar

So we are going to MULTIPLY to find out how many rands there are going to be.

1000 × 7.15 = <span>7150

<span>So, 7150 rands is your answer. 

Part b:-

To do this first we will DIVIDE. 

6274 </span></span>÷ 7.15 ≈ <span>877.482.......

So, 6274 rands is ABOUT $878.

Par a:- 7150 rands

Part b:- about $878.

Hope I helped ya!!!!!</span>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 1 - x² + x³

f(-1) is <em>x</em> = -1 for the function f(x)

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function f(x)]:                                                                           f(-1) = 1 - (-1)² + (-1)³
  2. Exponents:                                                                                                        f(-1) = 1 - 1 - 1
  3. Subtract:                                                                                                            f(-1) = -1

Pls, help with this question
nikklg [1K]

Answer:

m\text{ arc BC} =32\\m\angle 2=16\\m\angle3=74\\m\angle4=74\\m\angle5=16

Step-by-step explanation:

Arc BC is the intercepted arc for the central angle COB, so its measure is the <u>same</u> as the central angle.

Angle 2 is an inscribed angle, so its measure is <u>half</u> the measure of the intercepted arc BC.

Angles 3 and 4 are congruent inside an isosceles triangle (OB = OC, both radii), and the sum of all angles in triangle COB is 180 degrees, so

180 - 32 = 148 (sum of angles 3 and 4)

Each of angles 3 and 4 measure half that remaining 148 degrees.

Angle 5 is one of two congruent angles in an isosceles triangle AOC (OA = OC) so its measure is that of angle 2.
