I don’t understand the question above... pls give step by step explanation...
kirill115 [55]

Answer:

This is a linear function because the power of x is 1. Because of the +40 it's not a proportional relationship (they are in the form y = kx but the given equation is not) so the answer is the second option.

Find a rectangular equation. X = 3tan t, Y = 2sec t, for in (−π /2 , π /2 )
anzhelika [568]

Answer:

Step-by-step explanation:

x= 3tan(t) \rightarrow tan(t) = \frac{x}{3} \rightarrow tan^2(t) = \frac{x^2}{9}

y= 2sec(t) \rightarrow sec(t) = \frac{y}{2} \rightarrow sec^2(t) = \frac{y^2}{4}

sec^2(t) -tan^2(t) =1

\frac{y^2}{4} -\frac{x^2}{9} =1

is the rectangular equation of the parameter functions.

also, it is a hyperbola. The condition -\pi/2 < t limit x from 0 to infinitive

Any nonzero integer divided by 0 equals 0. True or false? Justify your answer.
Vanyuwa [196]
It is false. Although integers above 0 divided by 0 is 0, negative numbers can also be integers (-1,-3,-10, etc.), and when they are divided by zero, they are undefined. That means that it is not really a number.

A garden hose having an internal diameter of 0.740 in. ( 1.8796 cm ) is connected to a lawn sprinkler that consists merely of an
lara31 [8.8K]

Answer:

It will leave the sprinkler at speed of v_2=613.87m/sec

Step-by-step explanation:

We have given internal diameter of the garden hose d_1=0.740in=1.8796cm

So radius r_1=\frac{d_1}{2}=\frac{1.8796}{2}=0.9398cm

So area A_1=\pi r_1^2=3.14\times 0.9398^2=2.7733cm^2

Water in the hose has a speed of 4 ft/sec

So v_1=4ft/sec=121.92cm/sec(As\ 1ft/sec\ =30.48cm/sec)

Number of holes n = 36

Diameter of each hole d_2=0.1397cm

So radius r_2=0.0698cm

So area A_2=\pi r^2=3.14\times 0.0698^2=0.0153cm^2

From continuity equation

A_1v_1=nA_2v_2

2.7733\times 121.92=36\times 0.0153\times v_2

v_2=613.87m/sec
