One quart is approximately equal to 0.95 liter. To convert quarts to liters, which operation should you use?
Butoxors [25]

Answer:

the operation we use to convert quarts to liters : multiply  

Step-by-step explanation:

One quart is approximately equal to 0.95 liter

Here quart is the larger unit and liter is the smaller unit

To convert larger unit to smaller unit we multiply

given that 1 quart = 0.95 liter

2 quart = 2 times 0.95

3 quart = 3 times 0.05

so to convert quart of liter we multiply

the operation we use to convert quarts to liters we multiply by 0.95

Suppose an astronaut can jump vertically with an initial velocity of 5 m/s. The time that it takes him to touch the ground is gi
Vitek1552 [10]

Answer:

t=1.020s

Step-by-step explanation:

Given Equation:

5t-0.5at^{2} =0

Actually the given equation is the 2nd equation of motion

i.e. S =V_{i} t+0.5at^{2}

where S=0 because the astronaut jumps on the earth

and initial velocity V_{i}=5

to find time t, put the given value of a=9.8m/s^{2} in the given equation, we get

5t-0.5(9.8)t^{2} =0\\t(5-4.9t)=0\\ \ dividing\ both\ sides\ by\ t\ we \ get\\ 5-4.9t=0\\4.9t=5\\t=\frac{5}{4.9}\\ t=1.020s

it will take t=1.020s to reach the ground if he jumps on the Earth

Analyze a graph In Exercise,analyze and sketch the graph of the function.Label any relative extrema, points of inflation,and asy
ZanzabumX [31]

Answer:

Step-by-step explanation:

Given is a function f(x)

f(x) = e^x -e^{-\frac{{x}}{2}

We have to analyse and sketch the graph

X intercept : Put y =0, we get x=0

Y intercept: Put x =0 , we get y =0

No exception for x or y and hence set of all real numbers is domain and range.

f'(x) = (e^x +1/2 e^{-\frac{{x}}{2})

f' becomes 0 not at finite points

So relative extreme

Graph is sketched and attached
