A parking space shaped like a parallelogram has a base of 17 feet and a hight is 9 feet. A car parked in the space is 16 feet lo
wariber [46]

Answer:

57 ft²

Step-by-step explanation:

Lol I always found the area formula for a parallelogram to be interesting- it's like a rectangle, just the base times the height.

So to find this, you would subtract the area of the parallelogram by the area covered by the car.

(17ft · 9ft) - (16ft ·6ft) = 153ft² - 96ft²

= 57 ft²

Lol don't forget the units! A few of my teachers have been really picky about it, where if you don't include units, the entire answer is wrong : ( but either way, it's a good habit to pick up!

Which of the following sets of values correctly completes the t-chart for the equation y = 2x2 - 1.
natali 33 [55]

Answer:

The sets of values that correctly completes the t-chart are:

7, -1, 7

Hence, option B is true.

Step-by-step explanation:

Given the equation

y = 2x² - 1

FOR x = -2

substitute x = -2 in the equation

y = 2x² - 1

y = 2(-2)² - 1

y = 8 - 1

y = 7

FOR x = 0

substitute x = 0 in the equation

y = 2x² - 1

y = 2(0)² - 1

y = -1

FOR x = 2

substitute x = 2 in the equation

y = 2x² - 1

y = 2(2)² - 1

y = 8 - 1

y = 7

Thus, the t-chart becomes:

x              y

-2            7

0             -1

2              7

Thus, the sets of values that correctly completes the t-chart are:

7, -1, 7

Hence, option B is true.
