Answer:

10 x 10 x 10

Step-by-step explanation:

Since 10^3 is raised to the power of 3, 10 is multiplied by itself 3 times.

10 x 10 x 10 = $10^3$ = 1,000

Answer:

The airplane reaches its maximum height of 74 feet in 14 seconds.

Step-by-step explanation:

The easiest thing to do here is to plug in the two numbers given in the answer choices. Finding the height at 14 seconds and the height after 74 seconds is straightforward from here.

h (14) = -(14-14)²+ 74

h (14) = 0 + 74

h (14) = 74

h (74) = -(74-14)² + 74

h (74) = -(60)² + 74

h (74) = -3600 + 74

h (74) = -3,526

Now, we know that a height of an airplane won't be negative, as the height below the ground cannot be reached.

because our equation includes -(t-14)², any number greater than 14 will be a larger negative than 0--setting the height to an impossible number.

{However, we add +74 feet, so our t-14 could be any number that is less than 74 when squared (after first subtracting 14 from the number). Numbers like 15, (resulting in subtracting 1 from 74), 16 (resulting in -4 from 74), 17 (74-9), 18 (74-16), 19 (74-25), 20 (74-36), 21 (74-49), 22 (74-64) are still above the minimum input}

{So, our t could be up to 22, and any number above this maximum limit, such as 23, result in a height of 0}

for example: -(23-14)² + 74

-(9)² = -81

-81 + 74 = -7

All numbers below 14, which would end in an eventual negative outcome [ -(x)² = negative if x < 0 ]

are greater than a t of 14.

-(13-14)² = -1

; showing that t = 14 is our maximum height

(remember that if you have -(x)² you get the negative version of x² [pemdas. the negative outside of the parenthesis is equivalent to multiplying the parenthesis by -1. (E)xponents comes before (M)ultiplication].)

X and y<br> are supplementary angles. y<br> measures 142.<br> What is the measure of x?

Nimfa-mama [501]

Answer:

38°

Step-by-step explanation:

y = 142°

x + y = 180°{ being supplementary angles }

x + 142° = 180°

x = 180° - 142°

x = 38°

Hope it will help :)

Can some one pls help asap

leonid [27]

Answer: See the diagram below

==========================================================

Explanation:

She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.

---------------------

For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)

|48-58| = 10
|54-58| = 4
|57-58| = 1
|62-58| = 4
|69-58| = 11

This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.

---------------------

The last thing to do is find the mean of the set {10,4,1,4,11}

add: 10+4+1+4+11 = 30

divide by five: 30/5 = 6

The mean absolute deviation (MAD) is 6

This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.
