Here, volume of two shapes doesn't relate with each other, so if one has double dimensions than the other, then it's volume won't be exactly double than the other, 'cause they formula's are very different. 

 Volume of a Cylinder = πr²h
v = π(4)²(6)
v = 96π

Volume of a cone = 1/3 πr²h
v = 1/3 π (8)²(12)
v = 256π

So, Ratio = 256π/96π = 128/48 = 64/24 = 32/12 = 16/6 = 8/3 [ Not 2 ]

In short, She is Incorrect!

Hope this helps!

Which of the following is a function equivalent to f(x) = 3(1.7)4x? (5 points) f(x) = 25.06x f(x) = 3(8.35)x f(x) = 3(8.25x) f(x
denis23 [38]

Answer:


Step-by-step explanation:

Given:  f(x) = 3(1.7)4x

This can also be looked at as:  f(x) = 3 × 1.7 × 4 × x

You can multiply the three values four different ways and they will all be equivalent.

f(x) = (3 × 1.7) × 4 × x = 5.1(4)x

f(x) = 3 × (1.7 × 4) × x = 3(6.8)x

f(x) = 1.7 × (3 × 4) × x = 1.7(12)x

f(x) = 3 × 1.7 × 4 × x = 20.4x

The function A(b) relates the area of a trapezoid with a given height of 10 and
Natali [406]

Answer:

B(a)=\frac{a}{5} -7

Step-by-step explanation:

The input it taken as the unknown base value, while the output here is the area of the trapezoid. b is therefore the base value, and A( b ) is the area of the trapezoid. Let's formulate the equation for the area of the trapezoid, and isolate the area of the trapezoid. To find the inverse of this function, switch y ( this is A( b ) ) and b, solving for y once more, y ➡ y ⁻ ¹.

y = height * ( ( unknown base value ( b ) + 7 ) / 2 ),

y = 10 * ( ( b + 7 ) / 2 )

Now switch the positions of y and b -

b = 10 * ( ( y + 7 ) / 2 ) or b=\frac{\left(y+7\right)\cdot \:10}{2} - now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a,

y+7=\frac{a}{5},

y^{-1}=\frac{a}{5}-7 = B(a)

Therefore the equation that represents the inverse function will be the following : B(a) = a / 5 - 7
