Answer:

10 calories per minute

Step-by-step explanation:

We do not have much information to go on such as the speed that Tai is biking or his/her weight. Regardless we can use the data gathered by the University of Harvard which after a study came up with the following results. Their results showed that if an individual bikes at a speed of 13 mph and are around 155 pounds they will burn calories at a rate of 10 calories per minute. Therefore we can assume that Tai is burning roughly 10 calories per minute. This rate increases if the person bikes at a faster speed or weighs more as they are exerting more energy.

Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2

vladimir2022 [97]

ANSWER

$x=-0.62$ or $x=1.62$

EXPLANATION

For $-x^2+y=1$

We make y the subject to obtain,

$y=x^2+1$

We can easily graph this function, because we just have to transform the graph of $y=x^2$ by shifting the intercept up to $1$ .

As for the straight line, $-x+y=2$ ,

We find the intercepts as follows,

When $y=0,x=-2$ .

When $x=0,y=2$ .

We plot the points $(-2,0)$ and

$(0,2)$ .

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be

$x=-0.62$ or $x=1.62$

The population of a city (in millions) at time t (in years) is P(t)=2.6 e 0.005t , where t=0 is the year 2000. When will the pop

lora16 [44]

Answer:

year 2139

Step-by-step explanation:

The population will double when the factor e^(.005t) is 2.

e^(.005t) = 2

.005t = ln(2)

t = ln(2)/0.005 = 138.6

The population will be double its size at t=0 when t=138.6. That is the population will be about 5.2 million in the year 2139.
