Help me fast PLEASE The equation y = 1.6x represents the number of laps Henry can swim over time, where y is the number of laps

Phoenix [80]

The table is missing though but you may consider the following calculations :

Y = 1.6 x
for x = 1 minutes
Y = 1.6 laps
for x = 2 minutes
Y = 3.2 laps
for x = 3 minutes
Y = 4.8 laps

How do you write 11/ 4 as a percentage?

Ivan

The answer is %225 First, we must convert the given fraction into a decimal number. So use a calculator or long division to convert the given fraction to a decimal number. In this case,

Now just multiply the equivalent decimal by 100 to convert it into a percent. So . Take note that we're simply moving the decimal point two spots to the right.

So the given fraction is equivalent to 275%

Solve the quadratic equation. (x + 6)2 = 49

kykrilka [37]

Answer:

Step-by-step explanation:

To solve, use inverse operations:

$(x+6)^2=49\\\sqrt{(x+6)^2} =\sqrt{49} \\x+6=+/-7$

Now we solve for both +/- 7.

x+6=7

x=1

x+6=-7

x=-13

1) The x-axis represents the energy ( $E$ ), in joules. The y-axis represents the amplitude ( $x$ ), in milimeters.

2) The curve depicts an monotonous decrecent rate of change.

3) The amplitude is directly proportional to the root square of the energy.

<h3>How to analyze a graph relationship between two variables</h3>

In this question we have a relationship between two variables, in which we must apply principles of functional analysis to respond three questions presented in the statement.

Now we proceed to answer the three questions below:

What is on the x-axis? The y-axis? R/ The x-axis represents the energy ( $E$ ), in joules. The y-axis represents the amplitude ( $x$ ), in milimeters.
How would you describe the rate of change of the line? R/ The curve depicts an monotonous decrecent rate of change, that is, the slope converges to zero when the energy tends to infinite.
What does this tell you about the relationship between amplitude and energy? R/ The curve show a strong similarity with a function of the form $x = A\cdot \sqrt{E}$ . Hence, the amplitude is directly proportional to the root square of the energy.
