The defining characteristic of any geometric sequence is the common ratio, which is the constant found when dividing any term by the term preceding it.

C. He showed that f(n)/(f(n-1) was a constant ratio.

Tessa bought stock in a restaurant for $173.00. Her stock is now worth $242.20. What is the percentage increase of the value of

frozen [14]

Answer:

The percentage increase in Tessa's stock is 40%

Step-by-step explanation:

Given that:

Previous worth = $173

Worth now = $242.20

We have to find percentage increase which can be known by subtracting previous worth from present worth and multiplying it by 100:

Percentage increase = $242.20 - $173 = $69.2

Percentage increase = $69.2/173 *100

Percentage increase = 40%

The area of triangle formed by points of intersection of parabola y=a(x−1)(x−4) with the coordinate axes is 3. Find a if it is k

n200080 [17]

Answer:

The value of a will be $a=-\frac{1}{2}$

Step-by-step explanation:

Start by graphing the parabola and the three points of the triangle. These points are at intersections of y=a(x-1)(x-4) and the axes

so the y = 0 points are (1,0) and (4,0).

The x = 0 intersection is when y=a(-1)(-4) or (0,4a)

The base and height of this triangle are

The base would be the distance between the y=0 intersections and the height would be the y value of the other vertex.

Hence, base=3 units and height = 4a units. Thus, area can be calculated as

$A = \frac{1}{2}\times b\times h =\frac{1}{2}\times 3\times 4a = 3$

$a=\frac{1}{2}$

∵ the parabola opens downward therefore a will be negative.

hence, $a=-\frac{1}{2}$

What is x? answer fast please!

Sindrei [870]

Answer:

$\Huge \boxed{{x=15\°}}$

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

We can create an equation.

x + 165 = 180

Solve for x.

Subtract 165 from both sides.

x + 165 - 165 = 180 - 165

Simplify the equation.

x = 15
