Answer: I am not really sure but I think its c
Step-by-step explanation:
we can simply get the area of the whole rectangle, that is, the rectangle including the triangle in it, and then get the area of the triangle and subtract it from that of the rectangle, what's leftover, is the part we did not subtract, namely the shaded region.

Describe any patterns observed between buffer capacities and the concentration of acid or base in each buffer solution.
The higher the concentration of species in solution, the higher the buffer capacity.
What is a buffer?A buffer is a substance that mitigates against changes in acidity and alkalinity. The buffer capacity has to do with the greatest amount of acid/base that the buffer can effectively neutralize without a significant change in the pH of the solution.
We must know that the higher the concentration of species in solution, the higher the buffer capacity of the solution for any given ratio of [HA] to [A⁻] concentration.

Wanwan is 1.69 m tall and is flying a kite. She holds the string of the kite just above her head. The string is 80 m long and makes, x°, between 54° and 55° with the horizontal. Assuming that the string is taut, estimate (2 decimal places) the vertical height of the kite from the ground
Since, the kite is taut the vertical height of the kite from the ground is 66.82 meters
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore, the string length is the hypotenuse side. The angle formed is between 54 degree to 55 degrees. Therefore,
sin 54.5 = opposite / hypotenuse
sin 54.5 = h / 80
cross multiply
h = 80 × sin 54.5
h = 80 × 0.81411551835
h = 65.1292414685
Therefore, the vertical height of the ground from the ground is as follows:
vertical height = 65. 13 + 1.69 = 66.82 meters

what the 51st term of -17, -25, -33
Answer:
The 51st term of the arithmetic sequence is - 417
Step-by-step explanation:
The formula for determining the nth term of an arithmetic sequence is expressed as Tn = a + d(n - 1)
Where a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = - 17
d = - 25 - - 17 = - 33 - - 25 = - 8
n = 51
We want to determine the value of the 51st term, T51. Therefore,
T51 = - 17 + - 8(51 - 1)
T51 = - 17 - 400
T51 = - 417

Hey guys I need help with this no links and please explain your work
Answer:
x = 0.17
Step-by-step explanation:
Solve for x:
First, take the ln of both sides:
ln(1/16) = ln(8^(4x-2))
You can now bring down (4x-2) in front of the ln:
ln(1/16) = (4x-2)ln(8)
ln(1/16)/ln(8) = 4x-2
4x = ln(1/16)/ln(8) + 2
x = ln(1/16)/4ln(8) + 1/2
x = 0.17

solve the quadratic figures 3x^2 + x - 5
To solve this quadratic equation we should first see if it is possible to factorise it into two seperate brakets. In this case there are no numbers which multiply to give -5 and add to give 3. Thus we should resort to using the quadratic formula which is used when equations cannot be solved by inspection. The quadratic formula is x=(-b+-(b2-4ac)1/2)/2a. Values for a,b and c can be lifted from the question. ax2+b-c=0 so in this question a=3 b=1 and c=-5. Inputing these into the equation will give two results.
The answers are
x=1.135 or x=-1.468
both of these answers make the original equation true
