Step-by-step explanation:
Answer:
22.50m
Step-by-step explanation:
With the ground, the horizontal ground distance is the adjacent side, so by SOHCAHTOA, the ratio used is cosine, i.e.
Ground distance
= hypotenuse * cos(50°)
= 35 cos(50°)
= 35*0.64279
= 22.50m
Answer:
We just figure out what 3/4 of 20 is and it is 15 so 15 pens!
Step-by-step explanation:
The denominator cannot be zero, so
is not in the domain of 
.
is defined only for 
, and we have
so there is no issue here.
By the same token, we need to have
Taking all the exclusions together, we find the domain of is the set
or equivalently, the interval 
.
In the first equation, moving 2x over gives "y = -2x-11". Placing this into the second equation gives "3x - 4(-2x-11) = 11", or "3x+8x+44 = 11", which can be reduced to "11x= -33" or "x = -3". Replacing the "x" with -3 in the first equation gives "-6 + y = -11" or "y = -5". This gives a solution of (-3, -5), or answer C.
