The top of an electricity pole is supported by a rope of length 5 feet from the base of the pole. If the rope is one foot longer than the height of the pole, i.Draw a diagram to illustrate the statement aboveii.Find the height of the electricity pole iii.The length of the rope.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
The top of an electricity pole is supported by a rope of length 5 feet from the base of the pole. If the rope is one foot longer than the height of the pole,
i.Draw a diagram to illustrate the statement aboveii.Find the height of the electricity pole
iii.The length of the rope.
b)Throwing a rock upward from 160 feet above the ocean, the functionh(t)=−16t2+48t+160models the height(h)of the rock above the ocean as a function of time(t). Find:i.the zeros of this function which tell us when the rock will hit the oceanii.when the rock will be 160 feet above the ocean
