Answer: The parking lot in the drawing is 36 centimeters.
Step-by-step explanation:
Given: Actual width of parking lot = 54 meters
The scale she used was 2 centimeters : 3 meters.
i.e. 3 actual meters = 2 centimeters on drawing
⇒ 1 actual meter =
centimeters on drawing
⇒ 54 actual meters =
centimeters on drawing
⇒ 54 actual meters = 36 centimeters
Hence, the parking lot in the drawing is 36 centimeters.
Answer:
B.6
Step-by-step explanation:
Lisa was 48 inches tall when she was younger. She grew 2 1/2 inches per year. Lisa
is now 63 inches tall. How many years did Lisa grow for?
a. 5
b. 6
c. 7
d. 8
2 1/2=5/2
48+(5/2*5)=48+12.5=60.5
48+(5/2*6)=48+15=63
therefore it is answer b
y = -x² - 2x + 3
y - 3 = -x² - 2x + 3 - 3
y - 3 = -x² - 2x
y - 3 - 1 = -x² - 2x - 1
y - 4 = -(x²) - (2x) - (1)
y - 4 = -(x² + 2x + 1)
y - 4 = -(x² + x + x + 1)
y - 4 = -(x(x) + x(1) + 1(x) + 1(1))
y - 4 = -(x(x + 1) + 1(x + 1))
y - 4 = -(x + 1)(x + 1)
y - 4 = -(x + 1)²
y - 4 + 4 = -(x + 1)² + 4
y = -(x + 1)² + 4
(3,4)(5,16)
slope = (16 - 4) / (5 - 3) = 12/2 = 6
y = mx + b
slope(m) = 6
use either of ur points (3,4)...x = 3 and y = 4
sub and find b, the y int
4 = 6(3) + b
4 = 18 + b
4 - 18 = b
-14 = b
so ur equation is : y = 6x - 14
