<u>Solution-</u>
In order to get A'B'C' from ABC we have to do two steps,
they are
1- First we need to rotate the triangle around its own vertex C (-1 , 3)
2- Then moving the triangle 4 units downwards we will get the desired triangle.
After doing the first step the new co-ordinates of A,B,C will be,
(-2 , 4),(2 , 1) and (-1 , 3)
Then moving the triangle 4 units downward (i.e subtracting from y co-ordinate as we are moving in -ve y direction), the co-ordinates will be,
A' = (-2 , -3)
B' = (2 , -3)
C' = (-1 , -1)
I think the difference is 4x^2+x+1
Hope this helps
The circumference would be 30 ft, which comes from 6 people have 5ft of space each. 6 x 5 = 30. Which means the diameter is 9.55414013; Circumference divided by pi is the diameter. Once you divide the diameter by 2 for the radius, you get 4.777 which can be used to find the area of the table top. Area is pi x radius x radius = 3.14 x 4.777 x 4.777 =71.654 ft^2
Answer:
i think the answer is c but im not sure
Step-by-step explanation:
The jar has 138 grams of zinc.
<u>Solution:</u>
Given that , In a certain chemical reaction, the ratio of zinc to copper is 3 to 16.
A jar of the chemical contains 736 grams of copper.
We have to find how many grams of zinc does it contain
Let "n" be the grams of zinc needed for 736 grams of copper
Now, we know that,
16 grams of copper ⇒ 3 grams of zinc
Then, 736 grams of copper ⇒ n grams of zinc
So, by criss cross multiplication,
16n = 3 x 736
16n = 2208
n = 138
Hence, the jar has 138 grams of zinc.
