Answer:

4 cones

24 cones

Step-by-step explanation:

1. If order doesn't matter, we usually use combinations. In this case, we have 4 different flavors, and we're just choosing 3 of them:

4C3 = $\frac{4!}{3! * 1!}$ = 4 cones

2. If order does matter, we use permutations. In this case, we have 4 flavors and we want 3 from them:

4P3 = 4 * 3 * 2 = 24 cones

Y ≥ -3x + 2

It will be good to draw a graph and read the solution from the graph

y = -3x + 2

for x = 0 → y = -3 · 0 + 2 = 2 → (0, 2)
for x = 2 → y = -3 · 2 + 2 = -6 + 2 = -4 → (2, -4)

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,
