Answer:

a = 1√6

b = -2

Step-by-step explanation:

Hello,

To solve this trigonometric problem, we need to convert this values into fractions

a).

Sin45° = 1/√2

cos30° = √3/2

Sin60° = √3/2

Sin45° / (cos30° + sin60°) = [(1/√2) ÷ (√3/2 + √3/2)]

(1/√2) ÷ (√3/2 + √3/2)

Add √3/2 + √3/2

1/√2 ÷ 2√3/2

1/√2 × 2/2√3

2/2√(2×3)

2/2√6

1/√6

b

Cos 180° = -1

Sin150° = ½

Tan135° = -1

2cos180° - 2sin150° - tan135°

(2 × -1) - (2×½) - (-1)

-2 - 1 + 1 = -2

V125BC [204]

A cone that is sliced through the vertex would make the shape of a triangle.

You are told the h eight is 10 cm and the radius is 4 cm.

The radius would be half the base, so the base would be 4 * 2 =8 cm.

The area of the triangle is found by multiplying the base by the height, then dividing by two.

Area = 8 x 10 = 80

80 / 2 = 40 square centimeters.

I need help with this someone very smart at math this algebra 2
Mrac [35]

Answer:

value if a =

\frac{5}{4}

Step-by-step explanation:

here's the solution :-

=》

\frac{ 2(\sqrt{m})  {}^{3} }{ \sqrt[4]{m} }

=》

\frac{2(m {}^{ \frac{1}{2}} ) {}^{3} }{ {m}^{ \frac{1}{4} } }

=》

\frac{2 {m}^{ \frac{3}{2} }} { {m}^{ \frac{1}{4} } }

=》

2m {}^{ \frac{3}{2}  -  \frac{1}{4} }

=》

2m {}^{ \frac{6 - 1}{4} }

=》

2m {}^{ \frac{5}{4} }

so, a = 5/4

Graph y = 3x - 3 and label the x- and y-intercepts. My answer: (0,3)
Lesechka [4]
The slope-intercept form of the linear function is y = m x + b , where m is the slope and b is y-intercept.
Here we have: y = 3 x - 3
a ) When y = 0
0 = 3 x - 3
- 3 x  = - 3
x = ( - 3 ) : ( - 3 ) 
x = 1
When x = 0
y = 3 * 0 - 3 
y = - 3
So x - intercept is ( 1, 0 ) and y-intercept is ( 0, - 3 ).
b ) The slope:
m = ( y2 - y1) / ( x2 - x1 ) = 
= ( - 3 - 3 ) / ( 5- 7 ) = ( - 6 ) /( - 2 ) = 6 / 2 = 3
Answer: The slope m = 3 .
