If f(x)= 10 sin(x) – 3 then f (30%) = ?

marissa [1.9K]

Answer:

The value of f(30) is equal to 2.

Step-by-step explanation:

The given expression is :

$f(x)= 10 \sin(x) - 3$

We need to find the value of f(30)

Put x = 30 in above expression.

So,

$f(x)= 10 \sin(30) - 3\\\\=10\times \dfrac{1}{2}-3\\\\=5-3\\\\=2$

Hence, the value of f(30) is equal to 2.

Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Ha

Masteriza [31]

Answer:

The ages of the four siblings are: 5, 7, 9 and 11 years old.

Step-by-step explanation:

The computation of the age of the four siblings is shown below:

Given that

n = 4

a1 =? a2 =? a3 =? a4 =?

a4 = a1 + 6 years

S4 = 32

Based on the above information

As we know that

Sn = (a1 + a4) × n ÷ 2

S4 = (a1 + a4) × 4 ÷ 2

32 = (a1 + a1 +6) × 2

16 = 2a1 + 6

2a1 = 10

a1 = 10 ÷ 2

= 5

So, a4 = a1 +6

= 5 +6

= 11

a4 = a1 + (4-1) × d

11 = 5 + 3 × d

d = 6 ÷ 3

= 2

So,

a2 = a1 + d

= 5 + 2

= 7

a3 = a2 + d

= 7 + 2

= 9

Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

List the components in the proportion relationship used to find missing value in scale drawing?

Phoenix [80]

<h2>Explanation:</h2><h2></h2>

When we have relationships between two variables and their ratios are equivalent, we call this as proportional relationship. A scale drawing is a model that has been reduced or enlarged from its original size. Suppose you have a horse that measures 1,5m high by 2m long and want to draw a reduced model by a scale factor of 1:10, then your drawing will measure:

$Height=1.5(1/10)=0.15m \\ \\ Length=2(1/10)=0.2m$

So the components are:

Measurements of the original object
Measurements of the drawing
Scale factor

Jan is saving for a skateboard. She has saved $30 already, which is 20% of the total price. How much does the skateboard cost

White raven [17]

She has $30=20% of the total price so basically add 80% to 30. The total amount the skateboard costs is $150.00 she still needs $120.00 more
