(sin30° + cos30°) – (sin 60° + cos60°)​

Mathematics
1 answer:
Darya [45]2 years ago
8 0

Answer:

0

Step-by-step explanation:

Sin 30° = ½

Cos 30° = √3/2

Sin 60° = √3/2

Cos 60° = ½

Therefore,

(½ + √3/2) - (√3/2 + ½)

\frac{1 +  \sqrt[]{3} }{2}  -  \frac{ \sqrt{3 + 1} }{ 2 }

\frac{1 +  \sqrt{3}  -  \sqrt{3}  -  1}{2}

\frac{0 - 0}{2}

Answer: 0

Harman [31]

Answer:

y = 4/3x - 2, B is your answer

Step-by-step explanation:

Y intercept is the number next to slope(b).

The co efficient of x will be your slope so therefore the co efficient of x will be 4/3

y is always there because it will always be the dependent variable on the left side.

Find the total area of the entire figure. *
bonufazy [111]

Answer:

392.5 in²

Step-by-step explanation:

This figure is consists of a trapezium and a rectangle.

So, to find the total area of the figure you have to find the area of the trapezium and the rectangle separately  and add them together.

Let us find now.

<u>Area of the Trapezium</u>

Area = \frac{1}{2} × ( sum of the parallel sides ) × height

Area = \frac{1}{2} × (  9 + 20 ) × 5

Area = \frac{1}{2} × 29 × 5

Area = \frac{1}{2} × 145

Area = 72.5 in²

<u>Area of the rectangle</u>

Area = Length × Width

Area = 20 × 16

Area = 320 in²

<u>Total area of the figure</u>

Total area = Area of the trapezium + Area of the rectangle

Total area = 72.5 in² + 320 in²

Total area = 392.5 in²

Hope this helps you :-)

Let me know if you have any other questions :-)

If a line with a slope of -2 crosses the y-axis at (0,3). What is the equation of the line?
baherus [9]
It technically would be y=3x-3 in the y=mx+b formula, but it could also be rewritten 3x-y=3. Hope this helps!
