First let’s find the equation:
a = (42-21)/(26-13)
a= 21/13
y-y1 = a(x-x1)
y-21=(21/13)(x-13)
y-21=(21/13)x - 21
y=(21/13)x-21+21
y=(21/13)x

Now we will find the other point:
X = 2 >> y =(21/13)*2 = 3.23 (not)
X = 3 >> y =(21/13)*3 = 4.84 (not)
X = 4 >> y =(21/13)*4 = 6.46 (not)

X = 5 >> y =(21/13)*5 = 8.07 (yes) find the answer

Given that cos(30°) = cos(45°)cos(15°) + sin(45°)sin(15°), it follows that cos(30°) =

mario62 [17]

Answer:

$cos(30\°) = cos(45\°-15\°)$

Step-by-step explanation:

To solve this problem you must know the formula of subtraction of angles for the function cosx.

The formula is:

$cos(h-d) = cos(h)cos(d) + sin(h)sin(d)$

We can write 30° as: 45° - 15°

Then:

$cos(30\°) = cos(45\°-15\°)$

Using the formula for subtraction of angles we have:

$cos(45\°-15\°) = cos(45\°)cos(15\°) + sin(45\°)sin(15\°)$

Notice that we have achieved the expression shown in the statement

Finally:

$cos(30\°) = cos(45\°-15\°)$

Answer:

Step-by-step explanation:

First, substitute in 12 for x

2.4(12 ÷ 1/4)

Distribute 2.4 within the parenthesis

2.4 x 12 = 28.8

2.4 x 1/4 or 2.4 x 0.25 = 0.6

28.8 ÷ 0.6
