Rounded to one decimal place means to round to the nearest tenth (i.e. to the nearest 0.1)

4.25 (rounded to the nearest tenth) = <u><em>4.3</em></u>

The answer is 4.3 because you round up since 5 is in the hundredths place

Which of the following is false for the hyperbola (x+5)^2/4^2 - (y-2)^2/3^2=1
disa [49]

Answer:

C)One of the vertices is (-10,2)

Step-by-step explanation:

Given the hyperbola: \dfrac{(x+5)^2}{4^2} -\dfrac{ (y-2)^2}{3^2} =1

The standard equation for a hyperbola with a horizontal transverse axis is:

\dfrac{(x-h)^2}{a^2} -\dfrac{ (y-k)^2}{b^2} =1 where the center is at (h, k).

For our given hyperbola, the center (h,k)=(-5,2)

Now:

c^2=a^2+b^2\\c^2=4^2+3^2\\c^2=25\\c=5

Since the center is at (-5,2), its foci (-c,0) and (c,0) are:

(-5-5,2) and (-5+5,2)= (-10,2) and (0,2)

Similarly, since the center is at (-5,2), its vertices, (-a,0) and (a,0) are:

(-5-4,2) and (-5+4,2)= (−9,2), (−1,2).

Therefore, the odd option is C.

The required linear equation is given by y=10x + 15

The data collected by Harvard Business School plots the linear relationship of business startup success vs. Time.

<h3>What is Statistic?</h3>

The statistic is the study of mathematics which deal with relations between comprehensive data.

As clearly, points represents on graph startup success vs Time
part of a straight line
so we take two points on graph at (1,25), (2,35)
now equation of line

 y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)
= y-25=\frac{35-25}{2-1} (x-1)
y=10x+15

Thus, The required expression is given by y=10x + 15 which show the relation ship between startup success Vs time
