ANSWER:

STEP-BY-STEP EXPLANATION:

We have two toppings, the first is the ice cream container where there are two options and the second is the ice cream flavor where there are a total of three options.

Therefore, the number of possible ways to order ice cream would be:

$\begin{gathered} p=2\cdot3 \\ \\ p=6 \end{gathered}$

There are a total of 6 ways to order an ice cream

What basic trigonometric identity would you use to verify that sin x +1/ sin x=1 +csc x

SVETLANKA909090 [29]

Answer: The correct option is (c). $\csc x=\dfrac{1}{\sin x}.$

Step-by-step explanation: We are given to select the correct basic identity that we will use to verify the following:

$\dfrac{\sin x+1}{\sin x}=1+\csc x.$

We have

$\dfrac{1+\sin x}{\sin x}\\\\\\=\dfrac{1}{\sin x}+\dfrac{\sin x}{\sin x}\\\\\\=1+\dfrac{1}{\sin x}.$

In order to verify the given trigonometric equation, we must have

$1+\dfrac{1}{\sin x}=1+\csc x\\\\\\\Rightarrow \dfrac{1}{\sin x}=\csc x\\\\\\\Rightarrow \csc x=\dfrac{1}{\sin x}.$

Thus, the required identity that we will use is

$\csc x=\dfrac{1}{\sin x}.$

Option (c) is CORRECT.

Find the sum of all multiples of 4 between 25 and 100

Mademuasel [1]

Answer:

Sum of all multiples of 4 between 25 and 100 is 1116.

Step-by-step explanation:

Multiples of 4 between 25 and 100 = 28,32,36,40..............,96

let's check the series whether it is an arithmetic progression

a1 = 28 , a2 = 32 , a3 = 36 , a4 = 40

Common difference (d)=a2-a1=32-28 = 4

=a3-a2=36-32 = 4

=a4-a3=40-36 = 4

Common difference exists then the series of numbers is an Arithmetic progression.

To find number of terms :

a(a1) = 28 , d = 4 , l( last term ) = 96

l = a + (n-1)d

96 = 28 + (n-1)4

96 - 28 = (n-1)4

68 = (n-1)4

68/4 = (n-1)

17 = n - 1

17 + 1 = n

18 = n

Sum of all terms:

a = 28 , d = 4 , n = 18 , l = 96

Sn = n/2 ( a + l )

S18 = 18 / 2 (28 + 96)

S18 = 9 (124)

S18 = 1116

Therefore,Sum of all multiples of 4 between 25 and 100 is 1116.

NOTE:

Here 100 is also a multiple of 4 but question is asked between 25 and 100 so 100 is not considered in multiples.
