What is 4xy + x + 2xy

Consider figures 1 and 2 shown on the coordinate plane. Figure 1 has been transformed to produce figure 2. Graph shows 2 quadril

zvonat [6]

Using translation concepts, it is found that this transformation can be described as a reflection across the x-axis.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, considering the vertices of quadrilateral 1 and quadrilateral 2, the transformation from quadrilateral 1 to quadrilateral 2 has the following format:

(x,y) -> (x, -y).

Which means that it can be described as a reflection across the x-axis.

PLEASE HELP!! A car manufacturer does performance tests on its cars. During one test, a car starts from rest, and accelerates at

slega [8]

Answer:

0 ≤ t ≤ 25
16.348 seconds
310.0 meters

Step-by-step explanation:

a) Since these are production vehicles, we don't expect their top speed to be more than about 70 m/s, so the distance functions probably lose their validity after t = 25. Of course, t < 0 has no meaning in this case, so the suitable domain is about ...

0 ≤ t ≤ 25

Note that the domain for the second car would be 3 ≤ t ≤ 25.

__

b) The graph of this system shows the cars will both have driven the same distance after 16.348 seconds.

__

c) At that time, the cars will have driven 310.0 meters.

_____

<em>Non-graphical solution</em>

If you like, you can solve the equation for t:

d1 = d2

1.16t^2 = 1.74(t -3)^2

0 = 0.58t^2 -10.44t +15.66

t = (10.44 +√(10.44^2 -4(0.58)(15.66)))/(2(0.58)) = (10.44+8.524)/1.16

t = 16.348 . . . . time in seconds the cars are at the same distance

That distance is found using either equation for distance:

1.16t^2 = 1.16(16.348^2) = 310.036 . . . meters

The perimeter of the triangle shown is 30 inches. What is the length of the longest side of the triangle

Simora [160]

Answer:

The length of the longest side of the triangle is 13 inches

Step-by-step explanation:

step 1

Find the value of x

we know that

The perimeter of triangle is equal to the sum of its three length sides

so

$P=x+(2x+3)+(4x-8)$

$P=(7x-5) \ in$

we have

$P=30\ in$

substitute

$30=(7x-5)$

solve for x

$7x=30+5\\7x=35\\x=5$

step 2

Find the length of the longest side of the triangle

Remember that in a right triangle, the longest side is the hypotenuse

so

(2x+3) is the longest side

substitute the value of x

$2(5)+3=13\ in$

Answer:

Just because Michelle checked out 20% of her borrowed books were fictions does not mean Michael had more books. For example, Michelle could have borrowed 100 books, which would result into her borrowing 20 fiction books while Michael could have borrowed just 1 fiction book with a 100% of his borrowed books being a fiction book.

Step-by-step explanation:

Just because Michelle checked out 20% of her borrowed books were fictions does not mean Michael had more books. For example, Michelle could have borrowed 100 books, which would result into her borrowing 20 fiction books while Michael could have borrowed just 1 fiction book with a 100% of his borrowed books being a fiction book.

In other words, percentage is just the simplied ratio of something. Percentage cannot account for the original value and its original value cannot be assumed that it is small just because the percentage is small.
