Answer:
Find x;
tg 45º= x/7
x=7*tg45º
x=7*1=7
Answer= x=7
Find y;
Cos 45º=7/y
y=7/ Cos45º
y=7/(√2/2)=14/√2=14√2/2=7√2
Answer= 7√2≈9.9.

Answer:
y = -x/4 + 7/2
Step-by-step explanation:
Find the slope
( -2 , 4) ( 6 , 2)
m = (y2 - y1)/(x2 - x1)
x1 = -2
y1 = 4
x2 = 6
y2 = 2
m = ( 2 - 4)/( 6 -(-2)
m = ( 2 -4)/(6 +2)
= -2/8
= -1/4
Using point slope form equation
y - y1 = m( x - x1)
Using the second point
( 6 , 2)
x1= 6
y1=2
m = -1/4
y - 2 = -1/4(x - 6)
y - 2 = -(x - 6)/4
Open the bracket with -
y - 2 = (-x + 6)/4
y = ( -x + 6)/4 + 2
LCM = 4
y =( -x + 6 + 8)/4
y = (-x + 14)/4
Rearrange using slope intercept form
y = mx + c.
y = -x/4 + 14/4
We can break 14/4 by dividing by 2
y = -x/4 + 7/2
Answer:
a. 9 ft
b. 90 ° right angled
c. Right angle
d. 90°
e, Right angle
f. Angles on a straight line
g. 18 spots
Step-by-step explanation:
Here we have maximization question;
a. The separation distance of the dividing lines in a parking lot need to be far apart enough as to accommodate a vehicle with room to open the doors, therefore, it should be between 8.5 to 10 ft wide which gives a mean parking space width of approximately 9 ft
b. The angle of lines of the parking lot to the curb that will accommodate the most cars is 90°, because it reduces the width occupied by a car
c. The angle is right angled
d. Since the adjacent angle + calculated angle = angles on a straight line = 180 °
Therefore, adjacent angle = 90°
e. The angle is right angled
f. Angles on a straight line
g. The number of spots will be 162/9 = 18 spots.
