Given that sin θ = 3/4 and θ is in Quadrant II:
Find cos θ.

Answers

this is for the Sin

*Remember that sin = opposite / hypotenuse*

a² + b² = c² (where a and b are legs and c is the hypotenuse)

From the picture, you can see:

a = 3

c = 4

Plug these into the equation and solve for b.

* a² + b² = c² *

step 1: 3² + b² = 4²

step 2: 9 + b² = 16

step 3: b² = 16 - 9

step 4: b² = 7

step 5: √(b²) = √7

step 6: b = ± √7

FOR COS:

From the picture,  you can see that if θ is in quadrant II, b has to be negative.

b = -√7 = adjacent

Remember that cos θ = adjacent / hypotenuse.

cos θ = adjacent / hypotenuse

cos θ = (-√7 / 4)

select all the figures with 180° rotation symmetry.

A. image A: right, isosceles triangle

B. Image B: rectangle

C. Image C: square

D. Image D: regular pentagon

E. Image E: regular hexagon

plz help me

Answers

Answer: B, C and E

Explanation

A figure with a rotation symmetry will look the same, when rotated. The figures with [tex]180^o[/tex] rotation symmetry are:

B: rectangle

C: square  

E: regular hexagon

For a shape to have a [tex]180^o[/tex] rotation symmetry, the following must be true.

The shape must have an even number of sides (4,6...)The shape must have equal and parallel opposite sides.

Options (a) and (d) do not meet any of the above conditions.

However, the stated conditions are true for options (b), (c) and (e); because they have parallel & equal opposite sides; and they have an even number of sides.

Hence, the rectangle, the square and the regular hexagon have a [tex]180^o[/tex] rotation symmetry

See attachment for an illustration of rotation symmetry.

Find an equation of a line that is parallel to y = 5x + 9 and passes through
the point (3, 11).

Answers

Answer:

y = 5x - 4

Step-by-step explanation:

The equation y = 5x + 9 currently does not pass through the point (3, 11). It asks us to create the equation of a line parallel to y = 5x + 9. So all we have to change is the 9, where the line passes through the y-coordinate. The slope, 5x, has to stay the same, otherwise, the new line will not be parallel to  y = 5x + 9.

The line has to pass through to point (3, 11). The 3, stands for the x value, and 11 the y value. If we start at the y value of -4, that means the very next point would be (1, 1), and the next one, (2, 6), and the final one, (3, 11). This is because we know the slope of the line is 5x, that means for every 1 gained x value, the y value gains 5 values.

So, the equation of the new line would be this:

y = 5x - 4

Find the sum and the product of the roots of the equation: x^2+35x−51=0

what is the product of them?

Answers

Answer:

(a)

[tex]Sum = -35[/tex]

[tex]Product = -51[/tex]

(b)

[tex]Product = 1785[/tex]

Step-by-step explanation:

Given

[tex]x^2 + 35x - 51 = 0[/tex]

Required

(a) Determine the sum and product of the equation

(b) Determine the products of the (a)

Solving (a)

The general form of a quadratic equation is:

[tex]ax^2 + bx + c = 0[/tex]

Where

[tex]Sum = -\frac{b}{a}[/tex]

[tex]Product = \frac{c}{a}[/tex]

By comparison of [tex]ax^2 + bx + c = 0[/tex] tp [tex]x^2 + 35x - 51 = 0[/tex]

[tex]a = 1[/tex]

[tex]b = 35[/tex]

[tex]c = -51[/tex]

So:

[tex]Sum = -\frac{b}{a}[/tex]

[tex]Sum = -\frac{35}{1}[/tex]

[tex]Sum = -35[/tex]

[tex]Product = \frac{c}{a}[/tex]

[tex]Product = \frac{-51}{1}[/tex]

[tex]Product = -51[/tex]

Solving (b)

From (a) above, we have:

[tex]Sum = -35[/tex]

[tex]Product = -51[/tex]

Their product is:

[tex]Product = -35 * -51[/tex]

[tex]Product = 1785[/tex]
