Answer:

They Would be if they Have a pattern from left to right such as +2 or -5.

Step-by-step explanation:

If an example is counting up from 15 to 31 and 0 to 8 the pattern is Adding Two. So if the numbers decrease or increase in a certain way, then you can find out what it is and thn bam, your answer to the question.

Answer:

Sample Response: No. The last ratio is not written with the values in the same position as the others. It should be 50

10

to be consistent. If the ratio were written this way, then the ratios would all be equivalent . The relationship is proportional.

!!please help me quick!!<br> find the equation of the line.<br> y=__x+__
alexdok [17]
Y= 3x + 3. Use rise (how many it goes up or down) and divide it by run (how many it goes left or right) that number is your slope (aka M/ the number that goes with x. The number without the x attached is just where the line crosses the y axis

Can you please help me with solving this math problem. 1/4 (x+2)=5/6
Verdich [7]

So firstly, multiply both sides by 4 (the reciprocal of 1/4): x+2=\frac{20}{6}=3\frac{2}{6}

Next, subtract both sides by 2 and your answer will be: x=1\frac{2}{6}

Compare 4.6, 2.8..., square root 17, 3.9..., square root 8
Basile [38]
1. Square root 17= 289, Square root 8= 64.
289 = 289.00 \:  \: 64 = 64.00
4.6 > 2.8
289.00 > 64.00
289.00 > 4.6
4.6 > 3.9
2.8 < 3.9
Least to greatest:
2.8, 3.9, 4.6, 64.00, 289.00

The quadratic function h(t)=-16.1t^2 + 150 models a balls height, in feet, over time, in seconds, after it is dropped from a 15
katrin [286]
<h2>Hello!</h2>

The answer is: The first graphic representation.

<h2>Why?</h2>

We are given a quadratic equation, meaning that it could be two possible solutions for the exercise, however, we are talking about time, so we have to consider only the obtained positive values.

Let's make the equation equal to 0 in order to find the values of "t"

h(t)=-16.1t^2 + 150\\0=-16.1t^2 + 150\\16.1t^2=150\\t^2=\frac{150}{16.1}=9.32\\t=+-\sqrt{9.32}=+-3.05\\t1=3.05\\t2=-305

So, discarding the negative value, we can use the possitive value to find the correct graphic representation.

To find the correct graphic representation we must take into consideration the following:

- We must remember that the sign of the coefficient of the quadratic term (t^2) will define if the parabola opens downward or upward.

From the given quadratic (or parabola) equation we have:

a=-1\\b=0\\c=150

So, since the coefficient of the quadratic term is negative, the parabola opens downward.

- Since we are looking for a graphic that represents the change in height over time, we need to look for a graphic that shows only positive values for the x-axis (time)

- We are looking for a parabola which y-axis intercept is equal to 150.

Therefore, the graphic representation of the quadratic function that models a ball's height over time is the first graphic representation.

Have a nice day!

In 1934 there was an extreme drought and the Great Plains and the number 1,934 is the value of the nine and the hundredth place
WARRIOR [948]

It should be noted that No. the value of the 9 in the hundred place is not ten times the value of 3 in the tens place.

<h3>How to illustrate the information?</h3>

It should be noted that the value of 3 in 1934 is 30 and the value of 9 is 900.

1934 = 1000 + 900 + 30 + 4

Therefore the value of 9 will be:

= 30 × 3

Therefore, the the value of the 9 in the hundred place is 30 times the value of 3 in the tens place.
