Answer:

[tex](x,f(x)) = (-1,8)[/tex] -- Another point

[tex]a = 8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = a|x|[/tex]

[tex](x,f(x)) = (1,8)[/tex]

Solving (a): Another point

Substitute 1 for x and 8 for f(x) in [tex]f(x) = a|x|[/tex]

[tex]8 = a|1|[/tex]

Remove absolute bracket

[tex]8 = a*1[/tex]

[tex]8 = a[/tex]

[tex]a = 8[/tex]

Substitute 8 for a in [tex]f(x) = a|x|[/tex]

[tex]f(x) = 8|x|[/tex]

Let x = -1

[tex]f(x) = 8|-1|[/tex]

Remove absolute bracket

[tex]f(x) = 8*1[/tex]

[tex]f(x) = 8[/tex]

So, another point is:

[tex](x,f(x)) = (-1,8)[/tex]

Solving (b): The value of a

This has been solved in (a) above

[tex]a = 8[/tex]

What is a teansvarsal?

A transversal is a line that intersects two lines at two different points.

When a transversal intersects two lines at two different points two pairs of interior and exterior angles are formed.

If a transversal intersects two lines that are parallel to each other then the pair of corresponding and alternate angles are of the same measure.

We know adjacent angles share a common side.

In the given diagram ∠PSL is adjacent to ∠KRL because these two angles share a common side which is Line LM.

Write an expression illustrating the total vertical distance the dolphin traveled from the spot it was first sighted, according to the observations. Simplify the expression to find the total vertical distance the dolphin traveled.

Answers

Answer:

hello your question lacks some information hence I will provide a more general answer

answer :

The expression is ;  D = a + ar

Step-by-step explanation:

An expression illustrating the total vertical distance travelled by a body from rest ( "spot it was first sighted" ) as quoted in the question. can be written as

D = a + ar

where D = Total vertical distance travelled

           a = start term ( initial height )

           r = common ratio

Assume the probability is 1/2 that a child born at any time is a boy and births are independent. What is the probability of the event that if a family has 4 children, they are all boys? Please help!!!!!!!!! :(

Answers

There are only 23=823=8 possible ways to arrange the genders boy/girl, with repetition. Since the probability of boy and girl are equal, the probability of each of these arrangements are also equal. We can therefore count the number of possible "good" answers, and divide by 8.

There are 3 possible ways to have 1 boy, that being "first/second/third child is boy", so the probability of exactly 1 boy is indeed 3838.

Having at most 2 girls is the opposite of having three girls, so since there are only one way of having three girls, there must be 8−1=78−1=7 ways of having at most two girls, so the probability of at most two girls is indeed 78

ok for the first one. since 24/4 is 6 the first answer is correct but since each walk is $6 and 5 walks would get her $30. both answers are correct

then for the second one, you would start with 3 miles per 1 hour (because 6/2 is 3) and then the answer would be 9 miles in 3 hours because if she did 6 miles in 2 hours, 6+3 would be nine. so the last one is correct
