atroni [7]

Answer:

0.79 sec

Step-by-step explanation:

Given there is a tool at the top of the building which is dropped by a worker and it follows the following equation at every instant of time .

h(t)=-16t^{2} +h_{0}

where h_{0} =10 feet

We know that this height is measured from the base of the building which means that when the tool reaches the bottom of the building it has h = 0 feet.

Let this be done at time t

h(t) = 0

-16t^{2} +10=0

t^{2} =\frac{10}{16}

t=\frac{\sqrt{10} }{4}

t = 0.79 sec

Therefore the total time taken by the tool to reach the bottom of the building is 0.79 sec.

Write an equation for the statement: A kilogram is equal to approximately 2.2 pounds. A cinder block weighs x pounds. A brick ha
navik [9.2K]

the total mass in kilograms y of the cinder block and brick is  y=0.45x + 0.6 .

<u>Step-by-step explanation:</u>

Here we have , A kilogram is equal to approximately 2.2 pounds. A cinder block weighs x pounds. A brick has a mass of 0.6 kilogram. We need to find What is the total mass in kilograms y of the cinder block and brick . Let's find out :

According to given data in question ,

⇒ 1kg = 2.2pounds

⇒ 1(pounds) = \frac{1}{2.2}kg

A cinder block weighs x pounds and a brick has a mass of 0.6 kilogram . Let total mass in kg of the cinder block and brick is y , i.e.

⇒ y (kg)= x (pounds) + 0.6 kg

⇒ y (kg)= x (\frac{1}{2.2}kg) + 0.6 kg

⇒ y=0.45x + 0.6

Therefore , the total mass in kilograms y of the cinder block and brick is  y=0.45x + 0.6 .
