Answer:
D. [tex]g(x)=(x+4)^{2}-3[/tex]
Step-by-step explanation:
g(x) is a translated function. Compared to the parent function, f(x)=[tex]x^{2}[/tex], it has been shifted 4 left and 3 down. The rule for quadratic functions is [tex]y=a(x-h)^{2} +k[/tex], where h is the x-translation (horizontal) and k is the y-translation (vertical). In g(x) h=-4 and k=-3. While it might seem like h is positive, remember that since in rule it is being subtracted it must be negative.

Answers
Answer:
212.6 units²
Step-by-step explanation:
Area of the figure = area of rectangle + area of semicircle
✔️Area of rectangle = length * width
Length = 13
Width = 6*2 = 12
Area of rectangle = 156 units²
✔️Area of semicircle = ½(πr²)
r = 6
Area of semicircle = ½(π*6²) = ½(π*36) = 56.55 units²
✔️Area of the figure = 156 + 56.55 = 212.55 ≈ 212.6 units² (to nearest tenth)

suppose you fill the cone with water and empty the water into the cylinder. how many times will you empty the water from the cone into the cylinder.
A. 3 TIMES B. 6 TIMES C.9 TIMES
Answers
=========================================================
Explanation:
Recall that from a previous screenshot you posted, that
[tex]\text{Volume of Cone} = \frac{1}{3}*\left(\text{Volume of Cylinder}\right)[/tex]
If we multiply both sides by 3 and swap both sides, then we end up with
[tex]\text{Volume of Cylinder} = 3*\left(\text{Volume of Cone}\right)[/tex]
So that's why we need 3 cups of water, if each cup is the cone in the diagram. Keep in mind that the height of the cylinder and the cone must be same. The two radius values must be the same as well. You don't need to have r = h be true.

Answers
7,150,000
The population of Georgia is 10,500,000.
The population of Virginia is 30% less than that.
So the population of Virginia is 10,500,000 - 30% which equals 7,150,000
