How far is a football kicked if its y=-0.03x^2+1.53x

weqwewe [10]

The answer is 51 (not sure of the measurement unit). Assuming you mean the football hits the ground when it's kicked and lands somewhere downfield, y would be 0 (y means height from the ground, and if something is on the ground, it has no height. Hence, the 0). Set the equation equal to 0 and factor to solve for x. 0 = -.03x(x-51). 0 = -.03x and x = 0, or 0 = x-51 and x = 51

Starting with 54 and 36, replace the 54 with the greatest common divisor of 54 and 36, obtaining a1, and then replace 36 with th

nalin [4]

Answer:

1 time

Step-by-step explanation:

Given numbers are 54 and 36.

The greatest common divisor of 54 and 36 = 18

So, $a_1 = 18$ .

The least common multiple of 54 and 36 = 108

So, $b_1 = 108$ .

As 54 is replaced by $a_1$ and 36 is replaced by $b_1$ , so after applying the given procedure, the new number is

$(a_1, b_1)=(18, 108)\cdots(i)$

Now, apply the same procedure, to get $a_2$ and $b_2$ .

The greatest common divisor of 18 and 108 = 18

So, $a_2 = 18$ .

The least common multiple of 18 and 108 = 108

So, $b_2 = 108$ .

As $a_1$ is replaced by $a_2$ and $b_1$ is replaced by $b_2$ , so after applying the given procedure, the new number is

$(a_2, b_2)=(18, 108)$ which is the same as in equation (i)

Hence, after applying the procedure 1 time after $(a_1, b_1)$ , the obtained number $(a_2, b_2)$ is the same as $(a_1,b_1)$ .

ANDREA IS A VERY GOOD STUDENT. THE PROBABILITY THAT SHE STUDIES AND PASSES HER MATHEMATICS TEST IS 17/20. IF THE PROBABILITY THA

Eva8 [605]

Let B be the event that Andrea passes her test, and let A be the event
that she studies. We are given that P(A and B) = 17/20, and that P(A) = 15/16. 

Now the probability that Andrea passes her test given that she has studied 
is represented by P(BlA). The formula your teacher gave you can be written as 
P(BlA) = P(A and B) / P(A). 

So P(BlA) = P(A and B) / P(A) = (17/20) / (15/16) = (17/20)*(16/15) = 68/75.

vfiekz [6]

Answer: C. Adult women who are 30 to 70 years of age and live in the United States.

Step-by-step explanation:

The population in the study is the adult women who are 30 to 70 years of age and live in the United States. In statistics, a population is the whole or entire pool of items or event from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, church visits, food consumed or measurements. In the case above the population from which the sample was drawn is the adult women from age 30 to 70 that lived in the United States, no sample was drawn outside this population.
