I was playing my game mom said go feed the dogs i said no the i thought about it and i need to feed them
Answer:
z = 1.00
Explanation:
Given:
Probability of z value = 0.6826
By using standard normal table for z value.
P(-z < Z < z) = 0.6826
P(Z < z) - P(Z < -z) = 0.6826
We know that
P(Z < z) + P(Z < -z) = 1
So,
2P(Z < z) - 1 = 0.6826
2P(Z < z) = 1 + 0.6826
2P(Z < z) = 1.6826
P(Z < z) = 1.6826 / 2
P(Z < z) = 0.8413
So,
P(Z < 1.00) = 0.8413
z = 1.00
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.

The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.
<h3>How to reduce carbon emission</h3>
The burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.
In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.
Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.
By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.
Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.
