Well to solve this, there is a very easy way of doing it.

you can divide 18 divided by 2 which equals 9

so the 50% of 18 is 9

a way to check this if it's true is to do 9+9=18

The linear regression line for Tampa Tribune Database is y=8x+367. In approximately what year is the Tampa Tribune expecting to

lakkis [162]

The Tampa Tribune expecting to add 700 new pictures per year to their database in 2041

<h3>The linear equation of the graph</h3>

The equation of the line of best fit is given as:

$y = 8x + 367$

When the number of pictures added is 700, we have:

y = 700

Substitute 700 for y in $y = 8x + 367$

$700 = 8x + 367$

Subtract 367 from both sides of the equation

$333= 8x$

Rewrite the above equation as:

$8x = 333$

Divide both sides by 8

$x = 41.625$

Remove decimal (do not approximate)

$x = 41$

This means that:

$Year = 2000 +41$

$Year = 2041$

Hence, the Tampa Tribune expecting to add 700 new pictures per year to their database in 2041

Can someone answer this plz (-2z^2-14)-(-12z^2)

Orlov [11]

Answer:

$\large\boxed{(-2z^2-14)-(-12z^2)=10z^2-14}$

Step-by-step explanation:

$(-2z^2-14)-(-12z^2)=-2z^2-14+12z^2\qquad\text{combine like terms}\\\\=(-2z^2+12z^2)-14=10z^2-14$

It is a six-digit

KonstantinChe [14]

Ok, the first clue is it has six digit and the second clue is it’s a whole number!
So we know it lies between 99999 and 1000000
3rd clue tells it has only 3 different digits and 4th clue tells us each are used twice!
Moving on, 5th clue says none of its digits are even! 6th speaks none are divisible be 3
So the possibilities for digits are 1, 5, 7
And it’s greater than 600000, then the 1st digit must be 7! It is divisible be 5, so last digit must be 5!
7th clue states that It’s tenth digit is same as hundred-thousand! Means the tenth digit is 7
Let’s see what we got!
{7xxx75}
Clue no 8 as you can see says that it’s thousands digit is same as unit digit
So the number now is {7x5x75}
9th clue says it’s hundreds digit is different from tens digit meaning the hundreds digit is either 1 or 7 and we used 7 two times, so it’s 1 and clue 10 says it’s ten thousands digit is 1 so the number that’s playing hide ‘n seek or most probably riddle game is 715175!

[someone help] The speed of the object 7 seconds after it is dropped is ___m/sec

nadezda [96]

9514 1404 393

Answer:

68.6 m/s

Step-by-step explanation:

The speed at a given time is the derivative of the height at that time.

dh/dt = -9.8t

At t=7, the speed is ...

-9.8(7) = -68.6 . . . . . meters per second (downward)

The speed is 68.6 meters per second.

_____

<em>Additional comment</em>

Height is considered to be positive in the up direction, so velocity and acceleration are also positive in the up direction. The derivative of height will be the velocity. Its negative sign in this case indicates the object is moving in the downward direction. The speed is the magnitude (absolute value) of the velocity.
