Answer:\dfrac{3}{2}

Step-by-step explanation:

Tangent of an angle in right angled triangle is defined as the ratio of opposite side to adjacent side.

In triangle CAB,

Given that CB=1 and AB=2

tan(CAB)=\frac{CB}{AB}=\frac{1}{2}

In triangle BAD,

Given AD=3

tan(BAD)=\frac{BD}{AD}=\frac{BD}{3}

Since,angle BAD is same as angle CAB,their tangents are equal.

\frac{1}{2}=\frac{BD}{3}

So,BD=\frac{3}{2}

-18 = -6n - 6 + 2n Solve for n. ​
vodomira [7]

Answer:

n = 3

Step-by-step explanation:

-18 = -6n - 6 + 2n

-18 = -6n +2n -6 (Combine like terms)

-18= -4n -6

-18+6= -4n -6+6 (Addition Property of Equality)

-12 = -4n

-12/-4 = -4n/-4 (Division Property of Equality)

3=n

The value of 'n' is 3.

A company plans to sell a new type of cleaner for $280 each. The estimated cost, y, of manufacturing the cleaners is a function
Minchanka [31]
Suppose x is sold, $280 each , and y is the total financial cost. The first equation in the system is then certainly y = 280x.

The vertex form  <span>y-k = a(x-h)^2 where (h,k) is the vertex, and y is the y-intercept.

So, plug the values in.
</span><span>11,000-24,000 = a(0-500)^2
-13,000=250,000a
a=-0.052

y-</span><span>24,000 = -0.052(x-500)^2
y= </span><span>-0.052(x-500)^2 + 24,000
This is the second equation in the system.

The answer is then A, which contain the system </span><span>of equations which can be used to determine must be sold for the company to make a profit.</span>

Select the correct location on the table. Consider the following equations. f(x)= (x^2+3x+2)/(x+8) and g(x)= (x-1)/x. Approximat
zhannawk [14.2K]

Answer:

  (b)  -61/16 | -15/4

Step-by-step explanation:

We assume you're using a binary search successive approximation technique that starts with an interval and cuts it in half with each iteration. The final approximation of the solution to the equation will be the midpoint of the interval after it has been cut in half 3 times.

The graph shows the intersection point of the curves lies between x = -4 and x = -3.

If we define h(x) = f(x) -g(x), then our first iteration will evaluate h(-7/2) and determine which end of the interval gets replaced. The attachment shows us that the sign of h(-7/2) is the same as the sign of h(-3), so -7/2 replaces -3 and the interval after the first iteration is [-4, -7/2].

The midpoint of this interval is -15/4. The sign of h(-15/4) is the same as the sign of h(-7/2), so the interval after the second iteration is [-4, -15/4].

The midpoint of this interval is -31/8. The sign of h(-31/8) is the same as the sign of h(-4), so the interval containing the solution after the third iteration is [-31/8, -15/4]. The approximate solution value after 3 iterations is (-31/8 -15/4)/2 = -61/16.
