I'm pretty sure it's A
Explanation:
I did a few quick Google searches on ap classes because I myself do not take them a I read that most colleges do take ap classes as credit. it's no guaranteed however as it says many, not all. and for C I looked it up and I'm assuming they can be taken anywhere. take what I say with a grain of salt though because like I said I just googled it, hope it helps though.
The ball’s speed and direction at the lowest point of trajectory are; 3.1 m/s and swing to the same angle on the other side
<h3>What is the speed at the lowest point?</h3>
We will assume that all of the motion will transfer to Kinetic Energy at the lowest point. Now, the difference in height will be;
Δh = (130 – 130*cos °5) = 0.49 cm
The change in PE is;
ΔP.E = mgΔh
ΔP.E = 9.8m/s² × 0.75kg × 0.049 m
ΔP.E = 0.36015 J
Formula for kinetic energy is;
K.E = ¹/₂*m*v²
From conservation of energy;
K.E = P.E
Thus;
¹/₂* 0.075 * v² = 0.36015
v = √[(0.36015 * 2)/0.075]
v = 3.1 m/s
Thus, the pendulum will swing to the same angle on the other side.

What is the function of DNA polymerase?The main function of DNA polymerase is to synthesize DNA from deoxyribonucleotides, the building blocks of DNA. The DNA copies are created by the pairing of nucleotides to bases present on each strand of the original DNA molecule.
I'm not sure what is not a function of dna polymerase but I know what is
Answer:
1. Work questions out of order.
2.Tailor your strategy to each section of the ACT.
3.Build the right ACT prep plan for you
Answer:
P=380 ft.
Explanation:
Area=length x width
Perimeter= 2*length + 2*width
Width= 4*length + 8
A=5472 ft²
5472= l * (4l +8) (plug in values)
5472 = 4l² +8l (simplify)
4l² + 8l - 5472 = 0 (subtract 5472)
4(l² + 2l -1368) = 0 (factor out a 4)
4(l +38)(l-36)=0 (factor)
l=36 ft. (-38 is extraneous because it is negative)
5472=38*w
w=152 ft.
P=2(38) + 2(152)
P= 380 ft.
