Answer:
The tall of the flag pole is 51 ft answer (A)
Step-by-step explanation:
∵ The tall of the man = 6 ft
∵ The his shadow = 10 ft
∵ The shadow of the flag pole = 85 ft
∵ Tall of the man/tall of the flag = shadow of the man/shadow
of the flag
∴ 6/x = 10/85 ⇒ where x is the tall of the flag
∴ x = (6 × 85) ÷ 10 = 510 ÷ 10 = 51 ft
∴ The tall of the flag pole is 51 ft
Answer:
Two imaginary solutions.
Step-by-step explanation:
In order to simplify the equation, we square root both sides. As the argument (value in the root) is negative, and we know that the square root function's domain is only positive numbers, we would have two imaginary solutions.
This would be positive/negative .
Another way to visualize this is by looking at the parabola's graph. Through algebraic manipulation, we know that the parabola is z^2 + 45. This parabola never crosses the x-axis. Therefore there are two solutions that are imaginary.

Answer:
C(-3,3)
Step-by-step explanation:
Given
A = (7,-1)
B = (2,1)
AB:AC = 1:2
Required
Determine the coordinates of C
Since, B is between A and C; we need to determine ratio BC as follows;
Convert to division
<em>AC = AB + BC;</em>
Cross Multiply
Divide both sides by BC
Rewrite as
Write as ratio
Next is to determine the coordinates of C as follows;
Because B is between both points. we have:
Where
So; we're solving for x2 and y2
Where
Solving for x2;
Cross Multiply
Solving for y2;
Cross Multiply
<em>Hence, the coordinates of C are: C(-3,3)</em>
First write it out:
3y = -1/2x + 2
y = -x + 9
now sub in the y
3(-x+9)= -1/2x + 2
and solve.. [ill do it for you :)]
-3x + 27 = -1/2x + 2
now just simplify
27=2.5x + 2
-2 - 2
25 = 2.5x
25/2.5= 10
10=x... now for the y :/ but dont worry its simple just sub in the x which is 10 to the equation that seems the simplest which is the second one.
y = -(10) + 9
-10 + 9 = -1
x=10 y = -1
