Answer:
Option (2) and Option (4)
Step-by-step explanation:
From the picture attached,
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC =
=
=
= 12
Now, Sinθ =
=
Cosθ =
=
tanθ =
=
Therefore, Option (2) and Option (4) are the correct options.

Answer:
so b=-9 while c=12.
Step-by-step explanation:
If you have x-intercepts 1 and -4, then that means f(1)=0 and f(-4)=0.
You are given
So you have the system of equations to solve:
Evaluating the exponents:
Doing a little bit of multiplying:
Let's add 3 on both sides of equation 1 and 48 on both sides of equation 2:
Subtracting the equations will eliminate c.
Let's do that:
Divide both sides by 5:
Simplify:
If b=-9 and b+c=3 then -9+c=3 implies c=9+3=12.
so b=-9 while c=12.
Answer:
fourth time ...
same problem...
the red line crosses a corner of a box at (4,20) and (2,10)
20/4 = 5
and
10/2 = 5
the slope , constant, gradient for this relationship is "5"
Step-by-step explanation:
The answer is [-1,26]. The range between 4 and 9 is 5, and the range between 8 and -10 is 18, so you'd apply this to [4, 8] in order to find the other endpoint.
