42.09$ would be the correct answer, you just multiple 3.45 and 12.2 to get this answer
The height of the triangle is 11.3 in. The correct option is C. 11.3 in
<h3>Calculating height of triangle </h3>
From the question, we are to determine the height of the given triangle
The height of the given triangle is x in.
Now, we will determine the value of x
In the diagram, we can observe that the height divides the triangle into two equal halves
Thus,
By the<em> Pythagorean theorem</em>, we can write that
12² = x² + 4²
144 = x² + 16
144 - 16 = x²
∴ x² = 144 - 16
x² = 128
x = √128
x = 11.3
Hence, the height of the triangle is 11.3 in. The correct option is C. 11.3 in

Answer:
D: 0 and 1
Step-by-step explanation:
Function is defined by;
f(x) = 3x^(5) - 5x⁴
Now, an inflection point will be a point on the graph where the inflection or concavity changes.
Thus, let's find the derivatives until we get there;
f'(x) = 15x⁴ - 20x³
f''(x) = 60x³ - 60x²
So factorizing gives;
f''(x) = 60x²(x - 1)
At f''(x) = 0, we have; x = 0 or x = 1
Thus, the x coordinates of points of inflection are 0 & 1
I hope this helps you
x=-10 f (-10)=(-10)^4
f (-10)=10000
Answer:
Just guest: 38
Step-by-step explanation:
6÷4 = 1,5
So to make 6 to 4 we have: 6÷1,5 = 4
Similar to x: 57÷1,5 = 38
