The measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a  length of an arc of a circle of radius 7 is approximately 10.99 cm.

The radius r = 7 cm

The arc length l = 10.99 cm

We know,

l = rθ

θ is the central angle.

θ = l/r  = 10.99/7 = 1.57 radians

To convert 1.57 radians into the degree multiply it by 180/π

θ = 89.95 degree

Thus, the measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

From factoring, the given equation can be rearranged as  [tex]x=\frac{3n}{p}[/tex].

In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization.  One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.

For solving this question, the given equation should be rewritten  using the variables n and p in different sides. After that, you should  factor out a common term.

[tex]12n + 3px = 7px\\ \\ 12n=7px-3px\\ \\ 12n=4px\\ \\ x=\frac{12n}{4p} =\frac{4*3n}{4p}=\frac{3n}{p}\\ \\ x=\frac{3n}{p}[/tex]

A linear function is modeled by:

y = mx + b

In which:

Each of the stocks can be modeled by these following functions:

They will be equal when:

S1(t) = S2(t).

Hence:

39.63 + 0.3t = 24.45 + 0.8t

0.5t = 15.18

The decreasing of the prices and increasing of buying are correlated with the human behavior.

Demand graph is the curve in the study of economics which tells us about the number of units purchased or the demand of the product with respect to the price.

The demand line slopes downward means the price is decreasing and more people are buying it.

The increase in the buying of the goods on decreasing prices is affected by human behavior as when the price decrease , the middle class people have a tendency to buy more quantity and

even there is need to satisfy unsatisfied wants , If a product was costlier before and the prices have decrease then to satisfy the wants , the people buy it ,

Hence decreasing of the prices and increasing of buying are correlated with the human behavior.

Answer:

51°

Step-by-step explanation:

the given angle of 102° is the arc angle between the 2 segment end points on the circle arc.

and this arc angle is always a seen from the center of the circle.

by moving the reference point back (to the other side of the circle) to the circle arc that angle is cut in half.

you could move that point to anywhere on the arc of the circle outside of the 2 endpoints, and the angle stays always the same.

FYI - now, if you move that point into the top half-circle between the 2 end points, the perspective flips around, and that angle becomes half of the 360-102 = 258° arc angle.

The term best describes point X is option A. Centroid.

The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).

here, we have,

If the surface is plane triangle approximately and mass is uniformly distributed, then its center of mass will lie on the centroid of that triangle.

we have,

If the triangle has its vertices as (x1, y1) (x2,y2) (x3,y3)  

then the coordinates of the centroid of that triangle is given by:

Answer:

  68

Step-by-step explanation:

Any function is evaluated by putting the argument value where the variable is, then doing the arithmetic. When the argument is another function value, that function value is evaluated first.

__

The "o" in (fog) is a stand-in for the "ring operator" (∘) which is the operator used to signify a composition. A composition is evaluated right-to-left. That means (f∘g)(x) ≡ f(g(x)). The value of g(x) is found first, and is operated on by the function f.

Writing the composition in the form f(g(x)) lets you identify the layers of parentheses. As with any expression evaluation, the Order of Operations applies. It tells you to evaluate the expression in the innermost parentheses and work your way out.

To evaluate (f∘g)(-2) = f(g(-2)), we must first evaluate g(-2). That is ...

  g(x) = 5x +4

  g(-2) = 5(-2) +4 = -10 +4 = -6 . . . . . put -2 where x is, do the math

Now that we know g(-2) = -6, we know this expression is ...

  f(-6) = 8 -10(-6) = 8 +60 = 68 . . . . . substitute for x in 8-10x

Then the value we're looking for is ...

  (f∘g)(-2) = 68

8/4 = 2

Each term is obtained by multiplying the previous one by 2.

This is a geometric sequence with common ratio r = 2

the nth term

= a1r^(n-1)    where a1 = the first term

= 2(2)^(n-1).

[tex] a_{n} = 2_{n}[/tex]

Step-by-step explanation:

[tex]a_{1} = 2[/tex]

[tex]d = a_{2} - a_{1}[/tex]

[tex] = 4 - 2 = > 2[/tex]

Getting the nth term

[tex]a_{n} = a_{1} + (n - 1)d[/tex]

[tex] a_{n} = 2 + (n - 1)2[/tex]

[tex] a_{n} = 2 + (2n - 2)[/tex]

transfer the equation into slope intercept form. subtract 4x from each side getting 8y=-4x+30 then divide by 8.

The equation that represent the graph is  y = (1/2)eˣ , Option B is the correct answer.

An exponential function is what is denoted as y = eˣ

The graph has to be studied and the equation has to be determined.

To determine we will consider x = 0 for all the equation ,. which will give the y intercept , which is below 1 so Option C and D are stroked out.

Now we plot the graph for equation A and B

It can be easily understood from the graph that at x =0 , y = 0.5

Therefore , the equation that represent the graph is

y = (1/2)eˣ

The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and its angles.

__

The geometry of this problem can be modeled by a right triangle, so these relations apply. We are given an angle and adjacent side, and asked for the opposite side, so the relation of interest is ...

  Tan = Opposite/Adjacent

Using the given values, we have ...

  tan(24°) = AC/AB = (tree height)/(distance from tree)

  tan(24°) = AC/(22 m)

Multiplying by 22 m gives ...

  tree height = AC = (22 m)·tan(24°) ≈ 9.79503 m

The height of the tree is about 9.80 meters.
