Answer:
This question is incomplete, it lacks the diagram illustrating the circle and the options. The diagram has been attached. These are the options:
a. 10 pie cm2
b. 16 pie cm2
c. 356 pie cm2
d. 676 pie cm2
The answer is D
Step-by-step explanation:
The area of a circle is calculated by using the formula: πr^2, where r is the radius
According to the diagram in the attachment consisting of two circles; a small circle of radius GY=10cm and a large circle of radius YX=16cm.
Hence, Marco wants to create a new circle by using a radius GX i.e. the length of the line GX, which can be derived by adding GY + YX i.e. 10cm + 16cm = 26cm.
Therefore, GX is 26cm, meaning the radius of Marco's new circle will be 26cm.
To find the area of this new circle, we use the formula: πr^2, where r = radius = 26cm
Hence, Area = π × 26^2
26^2 = 26 × 26 = 676
π × 676
= 676π
Area of new circle= 676π squarecentimetres(cm2)

1. a. Pretty much, you just have to rearrange it so that the highest power is in the front. So, here's your answer:
b. It's a 4th-degree polynomial. A degree means that "what's the highest power?"
c. It's a trinomial. It has 3 terms, hence it's a trinomial.
2. a. Since it's an odd power and a negative coefficient, it will be:
x→∞, f(x)→-∞
x→-∞, f(x)→∞
b. The degree is even and the coefficient is negative, so it will be:
x→∞, f(x)→-∞
x→-∞, f(x)→-∞
3. a. This basically means that if you solve for x, you should get -2, 1, and 2. So, to do this, you can just write it in factored form and multiply inwards using any method of your choice (remember that in the parentheses, you should get the above value if you solve for x):
If you multiply it out, you get (also your answer):
4. The zeros are at x = 3, 2 and -7. Multiplicity of 3 is 1, for 2 it's 2, and for -7 it's 3.
Hope this helps!
