1 answer:
GrogVix [38]3 years ago

Answer:

DB = 6

Step-by-step explanation:

See the attached figure to the question.

Since O is the center of the given circle, so AB and CD are diameters of the circle.

Hence, AO = CO = OD = OB = radius of the circle = 6

In Δ OAC, we have AO = OC. Hence, ∠ A = ∠C = 60° {Given that ∠OAC = 60°}

So, ∠ AOC will automatically become 60°. {As the sum of all the angles of a triangle is 180°}

So, Δ AOC is equilateral triangle.

Now, ∠ AOC = ∠ BOD = 60°  {Since, they are vertically opposite angles}

Now, in Δ BOD, we have DO = OB. Hence, ∠ D = ∠ B = 60° {As the sum of all the angles of a triangle is 180°}

So, Δ BOD is also an equilateral triangle.

So, DB = BO = DO = 6. (Answer)

Drag each tile to the correct box consider the given functions f,g and h place the tiles in order from least to greatest accordi
Alja [10]

Answer:

Step-by-step explanation:

By definition, the average rate of change of a function f over an interval [a,b] is given by

\dfrac{f(b)-f(a)}{b-a}

compute the quantity

\dfrac{f(3)-f(0)}{3}

for all the three function

Average rate of change of f:

We will simply use the table to check the values for f(3) and f(0):

\dfrac{f(3)-f(0)}{3}=\dfrac{10-1}{3} = 3

Average rate of change of g:

We will use the graph to to check the values for g(3) and g(0):

\dfrac{g(3)-g(0)}{3}=\dfrac{8-1}{3} = \dfrac{7}{3}

Average rate of change of h:

We can plug the values in the equation to get h(3) and h(0):

h(3)=3^2+3-6=9+3-6=6,\quad h(0)=0^2+0-6=-6

And so the average rate of change is

\dfrac{h(3)-h(0)}{3}=\dfrac{6-(-6)}{3} = 4

There are 12-thirty second ads and 24-fifteen second ads. how many ads are there in minutes
MA_775_DIABLO [31]

Let's find the total number of seconds these adds take up:

t = 12(30) + 24(15)\\t = 720


Now let's convert this to minutes.

m = 720/60\\m = 12


There are a total of 12 minutes worth of ads.

Quincy uses the quadratic formula to solve for the values of x in a quadratic equation. He finds the solution, in simplest radic
julsineya [31]

Since the value of the discriminant (-19) < 0, no real solution(s)/root(s) exist for the equation. Thus, we can choose the first option:

"Zero, because the discriminant is negative".

A quadratic equation is a polynomial of degree 2, in a single variable x.

The standard form of a quadratic equation is ax² + bx + c = 0.

The quadratic formula is used to find the solution(s)/root(s) of this equation.

The quadratic formula is:

x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}

In this formula, b^2-4ac is called the discriminant (D).

The solution(s)/root(s) of the equation, depends on this discriminant value as follows:

  • When D > 0, the roots of the equation are real and distinct.
  • When D = 0, the roots of the equation are real and equal.
  • When D < 0, then no real roots exist.

In the question, we are given that the simplest form of Quincy's equation in the radical form was,

x = \frac{-3 \pm \sqrt{-19} }{2}.

Comparing this to the quadratic formula,

x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}

we get the discriminant (D) = -19.

Since the value of the discriminant (-19) < 0, no real solution(s)/root(s) exist for the equation. Thus, we can choose the <u>first option</u>:

"Zero, because the discriminant is negative".

Cindy made a triangular shaped sculpture with an area of 63 square inches. The height of the sculpture is 9 inches. What is the
jeyben [28]
Area=base times height times 1/2
63=area
9=height
63=bsae times 9 times 1/2
multiply both sides by 2 to get rid of 1/2
126=base times 9
divide both sides by 9
14=base

base legnth=14 inches
