Evaluate cos0 if sin0= 5/3​

Mathematics
1 answer:
Vladimir79 [104]3 years ago
5 0

Answer:

cos0 = 4/3

Step-by-step explanation:

If sin0 = 5/3 then cos0 = 4/3

Sin is opposite/hypotenuse or 5/3.

Cos is adjacent/hypotenuse or 4/3

I found 4 because of Pythagorean Theorem on the triangle, which is known as a 345 triangle.

What is the radius of the following circle?
Y_Kistochka [10]

Answer:

The radius is: 1

Step-by-step explanation:

The equation of a circle in center-radius form is:

(x - h)^2 + (y - k)^2 = r^2

Where the center is at the point (h, k) and the radius is "r".

Given the equation of the circle:

x^2+y^2=1

You can identify that:

r^2=1

Then, solving for "r", you get that the radius of the circle is:

r=\sqrt{1}\\\\r=1

Solve for x. 4(7x−3)−6=6−4(3x−7) Enter your answer in the box.
olasank [31]

4(7x−3)−6=6−4(3x−7)

Distributive property

28x - 12 - 6 = 6 - 12x + 28

28x - 18 = -12x + 34

28x + 12x = 34 + 18

40x = 52

   x = 52/40

   x = 13/10

or

   x = 1 3/10 (mixed number:  1 and 3/10)

Write the equation of line in slope-intercept form. Line parallel to y=0.5x+3 that passes through the point (−9,12)
Sliva [168]

A line parallel to the given one will have the same slope, 0.5. For the purpose here, it is convenient to start with a point-slope form of the equation, then simplify. For slope m and point (h, k), the equation of the line can be written as

... y = m(x -h) +k

We have m=0.5, (h, k) = (-9, 12), so the equation is ...

... y = 0.5(x +9) +12

... y = 0.5x +16.5

Use calculations and words to show<br>this quadrilateral meets the<br>definition of a kite.❤​
Y_Kistochka [10]

Answer:

Step-by-step explanation:

A kite is a quadrilateral that has only one line of symmetry, and bisecting diagonals.

From the graph,

AB = 6 units

BC = 8 units

CD = 8 units

AD = 6 units

i. Has exactly one pair of congruent sides. Examples are; AB = AD and BC = CD.

ii. The diagonals are perpendicular. AC is at right angle to DB.

iii. The diagonals bisect each other. AC bisects DB, or vice versa.

Therefore, quadrilateral ABCD is a kite.
