Hi there!

When writing a number in scientific notation we have to think about the following. Any number in scientific notation is written the following way.

$a \times 10 {}^{b}$

With a representing any number between 1 and 10 and b representing an integer. Therefore:

$44.5 = 4.45 \times {10}^{1}$

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: $\displaystyle k = 6$

You make blueberry mufﬁns and banana bread for a bake sale. One batch of blueberry mufﬁns requires m cups of ﬂour, and one batch

natali 33 [55]

The expression that represents the total amount of ﬂour (in cups) you need is Am+Bn. The correct option is D.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given that one batch of blueberry mufﬁns requires m cups of ﬂour and You make A batch of blueberry mufﬁns. Therefore, the total flour required for making A batch of blueberry muffins is,

Number of flour = A × m = Am

Also, Given that one batch of banana bread requires n cups of ﬂour and You make B batch of banana bread. Therefore, the total flour required for making B batch of banana bread is,

Number of flour = B × n = Bn

Now, the expression that represents the total amount of ﬂour (in cups) you need in total is,

The total amount of flour = Am + Bn

Hence, the expression that represents the total amount of ﬂour (in cups) you need is Am+Bn.
