17.64 to the nearest whole number is 18

The reason why is because the number after the point is bigger than five.

Also if the number after the point is 5 and above it can be rounded.

But if it is below five it cannot be rounded.

Answer: 18

1.) Simplify the expression.

miss Akunina [59]

Answer:

$sin ( u +\frac{\pi}{2} ) = cos (u)$

Step-by-step explanation:

Let us use the identity

sin(A+B)= cos(A) sin(B)+cos (B) sin(A) to simplify the given expression

Then

$sin(u + \frac{\pi}{2})= \cos \left(u\right)\sin \left(\frac{\pi }{2}\right)+\cos \left(\frac{\pi }{2}\right)\sin \left(u\right)$ --------------------(1)

Here

$cos (\frac{\pi}{2}) = 0\\$ ---------------------(2)

$sin(\frac{\pi}{2})= 1$ ---------------------(3)

Substituting the values in (1)

$sin(u + \frac{\pi}{2})= \cos \left(u\right)(1)+(0)\sin \left(u\right)$

$sin(u + \frac{\pi}{2})= \cos \left(u\right) + 0$

$sin(u + \frac{\pi}{2})= \cos \left(u\right)$

How are natural numbers, whole numbers and integers used in everyday life?

Nezavi [6.7K]

Natural numbers: Counting things! You look around your room and see an electronic device, then another, then another! You just counted to 3 using the natural numbers.

Whole numbers! You try to look for electronic devices and realise that they’re all gone. You have zero electronic devices, and you just used whole numbers.

You go online to find where your electronic devices went, and realise they were taken because you’re in debt to the bank so they took some of your stuff. You’re in negative numbers, and now you’ve used integers.

Maurinko [17]

Answer:

Php 770.00

Step-by-step explanation:

The cost of labor is ...

(hours) × (hourly rate)

= (3 h) × (Php 150.00/h) = Php 450.00

The total cost is ...

total cost = cost of labor + cost of parts

= (Php 450.00) + (Php 320.00) = Php 770.00

Randolf owes Mr. Solidarios Php 770.00 for the repair.
