Answer:
Step-by-step explanation:
We have been given that a square pyramid has a base with a side length of 7.5 feet and lateral faces with heights of 16 feet. We are asked to find the surface area of the square pyramid.
We will use surface area of square pyramid to solve our given problem as:
, where,
a = Length of each side of base,
h = Height of lateral face.
Upon substituting our given values in above formula, we will get:
Therefore, the surface area of the given square prism would be 592.50 square feet.
Just simplify the given equation
y = 7.2 + 4(x-2)
y = 7.2 + 4x - 8
y = 4x - 0.8
Now they want to know the answer if X = 2
y = 4(2) - 0.8
y = 8 - 0.8
y = 7.2
Answer:
1. Not rhombus
2. Rhombus
3. Rhombus
Step-by-step explanation:
The little lines you see represent the size. So if you see one line on all sides, its a rhombus. If you see 1 line on one side, 2 lines on two sides, and 3 on the last side, it is not a rhombus.
Look for the lines.
By changing the sign of x coordinates the point would be reflected along "y" axis.
Step-by-step explanation:
Let us plot a hypothetical point (x, y) where both x and y are positive integer. Since both the number sets are positive integer, hence the points lie in 1st quadrant.
Now we change the sign of the x coordinates i.e. x=-x
The new coordinates are (-x, y)
since x is negative and y is positive hence this set would lie in 2nd quadrant.
Comparing the above two pointset (x, y) and (-x, y)
We find that 2nd set is the reflection of the 1st set along y axis (“y” remains constant and sign of “x” coordinates change)
Hence if the original point is in 1st quadrant then the after changing the sign points would lie in 2nd quadrant and vice-versa.
Similarly, if both the values of “x” and “y” are negative i.e. points lie in 3rd quadrant, then the points would lie in 4th quadrant after changing and vice-versa
Well first round to the nearest whole then add then subtract then you will get your answer
