Romashka [77]3 years ago

Answer:

\frac{4\sqrt{7}}{7} \text{ and } \frac{3\sqrt{7}}{7}

Step-by-step explanation:

if \sec x = \frac{4}{3}, then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.

The other leg (specifically the opposite one) will be equal to \sqrt{16-9} = \sqrt{7} by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = \frac{4}{\sqrt{7}}=\frac{4\sqrt{7}}{7}.

cot(x) is defined as adjacent over opposite, which is equal to \frac{3}{\sqrt{7}}=\frac{3\sqrt{7}}{7}

That means that the first option, the leftmost one, is correct.

The distance d in miles that can be covered by a rabbit in X hours is given in the equation y = 30 x The distance covered by a b
AveGali [126]

Answer:

Rabbit is faster than bear.

Step-by-step explanation:

Speed of rabbit or bear is determined by their rate of change of their distances with time.

The distance covered by rabbit in x hours is given as:

y=30x

The above equation is of the form y=mx, where, m is the rate of change of y with x.

Therefore, the rate of change of rabbit's distance with time is 30 mi/h.

Now, from the graph, the slope is given as the rise over run.

Rise is 50 miles and run is 2 miles.

So, rate of change of bear's distance with time is, m_b=\frac{50}{2}=25\ mi/h

Now, 30 is greater than 25. So, rabbit is faster than bear.

The motion of an object was recorded by measuring the velocity of the object in meters per second at various times, as shown in
LekaFEV [45]

The regression equation that represents the relationship between velocity and time is:

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v), that is, time and velocity, are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.
