Answer:
C) 147 ft²
Step-by-step explanation:
Bottom rectangle:
A = bh
A = 14(7)
A = 98
Top rectangle:
A = bh
A = 7(7)
A = 49
Combined:
98 + 49
147
Answer:
P(7, -7)
Step-by-step explanation:
Xp = 6+ ⅓(9-6)= 6+ ⅓(3)=6+1 =7
Yp = -10 + ⅓(-1+10)= -10+⅓(9)= -10+3=-7
=> P (7, -7)
Answer: OPTION D.
Step-by-step explanation:
The missing figure is attached.
As you can observe in the figure AC and BD intersect each other at the point O. Then, you can identify that:
Subsitute values:
Solve for "x":
Therefore:
They are 360 degrees in a circle. Then:
Substituting values and solving for arc BC, you get:
The coefficient of x in the equation of the given line, 3, is its slope. The slope of the perpendicular line is the negatve reciprocal of that, -1/3. You now have the slope and a point on the perpendicular line, so you can write its equation using the point-slope form:
y = m(x -x₁) +y₁
where m is the slope and (x₁, y₁) is the point.
An equation for your perpendicular line is
y = (-1/3)(x -(-1)) -3
y = (-1/3)x -10/3
The slope-intercept form of the equation of the perpendicular line is ...
y = (-1/3)x -10/3
