Answer:
No triangle
Step-by-step explanation:
All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.
I hope this helps!
To solve the question, we will estimate how many times Titicaca was larger than Texcoco. Here we shall use the formula:
(Area of Titicaca)/(Area of Texcoco)
Area of Titicaca=3.232×10^4
Area of Texcoco=2.1×10^3
thus the number of times <span> as great is the area covered by Lake Titicaca as opposed to the Lake that the Aztecs built on
(3.232</span>×10^4<span>)/(2.1</span>×10^3<span>)
=15.391 times</span>
Answer:
-150
Step-by-step explanation:
If you do an= a+(n-1)d a(n) being similar to f(x) just a different variable. Where a(41)= 50+(41-1)(-5) i would say the 41st term in the sequence is -150 because the sequence is going down, I'm not positive, but I know the formula is right. a is the term similarly to f, n is similar to x it is the number of the term, and d is the constant which in this case is -5.
Answer:
Step-by-step explanation:
Since the coefficient of x^2 is positive, this quadratic is a parabola in the shape of a U, hence has a minimum.
We want to end up with the form (x-h)^2 + c. Since (x-h)^2>=0, this form shows that the minimum is achieved when x=h.
Completing the square will put the quadratic in the desired form. Note that:
(x-h)^2=x^2-2hx+h^2
Comparing this with the given form, we must have -8=-2h, or h=4. But we are missing h^2=4^2=16. We can add the missing 16 and subtract it elsewhere without changing the quadratic.
x^2-8x+16 + (16-4) = (x-4)^2 + 12
Now we know that at x=4 the quadratic has a minimum and that the minimum is 12.
we are given
equilateral triangle
we can see that triangle ACD is a right angled triangle
so, we can use Pythagoras theorem for this triangle
hypotenuse=AC
Adjacent=CD
opposite=AD=a
and
now, we can use Pythagoras theorem
and we get
now, we can plug values
now, we can solve for a
so, option-A..........Answer
