Answer:
I(x) = 12x² + 8x + 5
Step-by-step explanation:
* Lets talk about the solution
- P(x) is a quadratic function represented graphically by a parabola
- The general form of the quadratic function is f(x) = ax² + bx + c,
where a is the coefficient of x² and b is the coefficient of x and c is
the y-intercept
- To find I(x) from P(x) change each x in P by 2x
∵ P(x) is dilated to I(x) by change x by 2x
∵ I(x) = P(2x)
∵ P(x) = 3x² + 4x + 5
∴ I(x) = 3(2x)² + 4(2x) + 5 ⇒ simplify
∵ (2x)² = (2)² × (x)² = 4 × x² = 4x²
∵ 4(2x) = 8x
∴ I(x) = 3(4x²) + 8x + 5
∵ 3(4x²) = 12x²
∴ I(x) = 12x² + 8x + 5
Not sure if this is accurate but i multiplied everything to get 243/2, 121.5, or 121 1/2
Answer: 16
Step-by-step explanation: we will do PEMDAS for this. first 6-3= 3 this makes the equation 4+8/2*3
next, 8/2 because of pemdas. this is 4. this makes the equation 4+4*3. nest do 4*3. this is 12. then just add 4 to make 16.
Answer:
x= -4
graph with a closed circle over the intended number
Step-by-step explanation:
These inequalities are basically the same steps as equation.
Step 1: subtract 7 from the 19 on the other side of the equation, this equals 12
Step 2: divide -3 by 12 this equals -4
For these equations, you have to inverse the operations (i.e + to -). that is why you subtract and divide. (-3x) is the same as multiplication. The coefficient and variable are being multiplied.
If you know the cone volume and the cone radius, then
height = 3*Volume / PI * r^2
answer is D
