The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.

Answers

Answer:

The toy reaches the ground in 10 sec

Step-by-step explanation:

When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,

Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,

the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.

The quadratic formula is as follows:

-b ± √discriminant

t = -------------------------------

which here is:

-50 ± 50.39

t = ------------------------ Since t represents time, only the positive result

-9.8 is relevant here; it is 10.24 sec,

which rounds off to 10 sec

The toy reaches the ground in 10 sec

it reaches the ground in 10 sec

Answers

Answer:

Step-by-step explanation:

First, multiply the 2 factors that add up to 8.

1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.

Divide and multiply 2 by 8 and 1/3. Then, we solve for y.

y = 2/3x - 4

Answers

Answer:

it depends on the work place to play it safe i would choose 12

Step-by-step explanation:

The sample mean is equal to 24 and population mean is equal to 25

What is sample mean?

Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.

Sample mean= sum of the terms/number of the terms

What is population?

The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.

Population mean= sum of the population/ number of the population

From the given question average of entire year is 25.

According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.

According to the sample mean formula,

sample mean= sum of the terms / number of the terms

⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24

Thus the sample mean is equal to 24 and population mean is equal to 25
