The limit is equivalent to the value of the derivative of \cos x at x=\dfrac\pi2. (See definition of derivative)

(\cos x)'=-\sin x\implies (\cos x)'\bigg|_{x=\pi/2}=-\sin\dfrac\pi2=-1

Lindsey found a cupcake and weighed it on a digital scale. The cupcake weight 0.35 lb. what is the weight of the Rock in expande
SVEN [57.7K]

The weight of the cupcake in an expanded form is 3.5 * 10⁻¹ lb

<h3>How to determine the weight?</h3>

The weight is given as:

Weight = 0.35 lb

Remove the unit

Weight = 0.35

Multiply the weight by 1

Weight = 0.35 * 1

Express 1 as 10/10

Weight = 0.35 * 10/10

Evaluate the product

Weight = 3.5 * 1/10

Express 1/10 as an exponent

Weight = 3.5 * 10⁻¹

Return the unit

Weight = 3.5 * 10⁻¹ lb

Hence, the weight in expanded form is 3.5 * 10⁻¹ lb

Given the diagram, a supplement to ∠ABC could be<br><br> ∠BDC<br> ∠DAB<br> ∠ADC<br> ∠BAC
Zina [86]

Answer:

Supplement to ∠ABC: ∠DAB acts as a possible supplement

Step-by-step explanation:

There are two approaches to this problem:

1. We can identify an angle by it's measure such that it adds to 180° when added to the m∠ABC

2. As this shape is a quadrilateral, we can tell that two adjacent angles are supplementary to one another, and thus can be identified as the supplement to ∠ABC

For the simplicity, lets take the second method into consideration. We see that ∠ABC is adjacent to the two angles - ∠BCD, ∠BAD. These angles can be rewritten as such: ∠DCB, ∠DAB. And, as we can see from the options, ∠DAB is one of them that may act as a supplement. Shall we check?

The m∠ABC is 110° (degrees) so that it's claimed supplement, ∠DAB should be 70° as to satisfy the first condition of adding to 180°. And, we can see from the diagram that 40° + 30° = 70° so that both "approaches" are met!
