Step-by-step explanation:

Step 1: Define

Identify

Continuous at x = 2

$\displaystyle f(x) = \left \{ {{2x^2 \ if \ x < 2} \atop {x + k \ if \ x \geq 2}} \right.$

Step 2: Solve for k

Definition of Continuity: $\displaystyle \lim_{x \to 2^+} 2x^2 = \lim_{x \to 2^-} x + k$
Evaluate limits: $\displaystyle 2(2)^2 = 2 + k$
Evaluate exponents: $\displaystyle 2(4) = 2 + k$
Multiply: $\displaystyle 8 = 2 + k$
[Subtraction Property of Equality] Subtract 2 on both sides: $\displaystyle 6 = k$
Rewrite: $\displaystyle k = 6$

Arrange these numbers in increasing order: 216,000,000, 2.2 × 10 to the 3rd power, 3.1 × 10 to the 7th power, 310,000

ziro4ka [17]

216,000,000
2.2 × 10 to the 3rd power = 2.2 * 10^3 = 2,200
3.1 × 10 to the 7th power = 3.1 * 10^7 = 31,000,000
310,000

Increasing order:
2,200 , 310,000 , 216,000,000 , 31,000,000

So increasing order with original numbers:
2.2 × 10 to the 3rd power, 310,000, 216,000,000, 3.1 × 10 to the 7th power

M∠A = 40º

denis23 [38]

180-40=140. 140/5 = 28

x= 28

angle B: 5(28) = 140
140 + 40 = 180

180=180
