Answer:
-1/3
Step-by-step explanation:
Take the ratio of the corresponding sides to get the scale factor so for this equation let's use the hypotenuse.
The length of the hypotenuse of the larger triangle is 12 units and the smaller triangle's hypotenuse is 4 so 4/12 is the scale factor.
However 4/12 can be simplified down to 1/3.
Since the smaller triangle has been flipped upside down the scale factor is negative so the final answer is -1/3
16*X² +81
The answer is 3
(4x+9i)(4x−9i) = (4x+9i)*4x -9i((4x+9i)) = 16x2 +36i -36i -81i2 = 16x² -81(-1)
= 16x² +81
Answer:
Relative minima at 
, and relative maxima DNE.
Step-by-step explanation:
The given function is f(x) = x (x + 7) ...... (1)
We have to calculate the relative maxima and relative minima at point (x, y).
Rearranging the function given above we get.
⇒ 
Now, this is an equation of parabola having vertex at and the axis is parallel to positive Y-axis.
Therefore, the function(1) has a relative minima at , and the relative maxima DNE. (Answer)
Answer:
56 m²
16 m²
88 m²
Step-by-step explanation:
The formula for the area of a rectangle is:
A=L×W (area=length × width)
A=7×8
A=56m²
The formula for the area of triangle is:
1/2×b×h (1/2 × base × height)
A=1/2×4×8
A=2×8
A=16m²
For the total area you will now add the area of each shape. We will multiply triangle area by 2 because there is 2 triangles.
A=56+2(16)
A=56+32
A=88m²
Answer:
1 ton is equal to 2000 lbs
To find how many lbs is 3 tons, multiply 2000 by 3
2000 times 3 is 6000
So, 3 T = 6000 lbs
