Answer:

Step-by-step explanation:

Brayden's car travels 37.1 miles per gallon.

Dylan's car travels 48.4 miles/(2 gallons) = 24.2 miles per gallon.

37.1 - 24.2 = 12.9

Dylan's car gets 12.9 miles per gallon less than Brayden's car.

Given the preimage and image, find the dilation scale factor

77julia77 [94]

Given:

The preimage and image of a triangle in the given figure.

To find:

The dilation scale factor.

Solution:

From the given figure it is clear that the vertices of the triangle ABC are A(-2,-2), B(-1,2) and C(2,1).

The vertices of the triangle A'B'C' are A'(-4,-4), B'(-2,4) and C'(4,2).

If a figure is dilated by factor K with (0,0) as the center of dilation, then

$(x,y)\to (kx,ky)$

Let the scale factor be K, then the image of point A is:

$A(-2,-2)\to A'(k(-2),k(-2))$

$A(-2,-2)\to A'(-2k,-2k)$

From the given figure it is clear that the image of point A is A'(-4,-4).

$A'(-2k,-2k)=A'(-4,-4)$

On comparing both sides, we get

$-2k=-4$

$k=\dfrac{-4}{-2}$

$k=2$

Therefore, the dilation scale factor is 2.

1. We can conclude that the result of the division is $x-13$ with a remainder of $4x-9$ , or in other notation: $x-13+ \frac{4x-9}{x^2+3}$ . Check the steps in the first image.

3. We can conclude that the result of the division is $x^{2} +6x+3$ with a remainder of 2, or in other notation: $x^{2}+6x+3+ \frac{2}{x-1}$ . Check the steps in the firts image.

5. We can conclude that the result of the division is $x+1$ with a remainder of 5, or in other notation: $x+1+ \frac{5}{x-4}$ . Check the steps in the first image.

7. To check if $x+4$ is a factor of $x^{3}+3x^{2}-10x-24$ , we are going to perform long division. If the result of the long division has no remainder, $x+4$ is a factor of $x^{3}+3x^{2}-10x-24$ .
Since the result of the long division has no remainder, we can conclude that $x+4$ is a factor of $x^{3}+3x^{2}-10x-24$ . Check the steps in the second image.

9. To check if $x-3$ is a factor of $x^{3}+3x^{2}-10x-24$ , we are going to perform long division. If the result of the long division has no remainder, $x-4$ is a factor of $x^{3}+3x^{2}-10x-24$ .
Since the result of the long division has no remainder, we can conclude that $x-4$ is a factor of $x^{3}+3x^{2}-10x-24$ . Check the steps in the third image.

10. We can conclude that the result of the synthetic division is $-2x^{2}+9x+5$ . Check the steps in the fourth image.

Find other values of a, b, and c so that log(a) + log(b) + log(c) = log(a + b + c).

yanalaym [24]

Step-by-step explanation:

Given :

log(a) + log(b) + log(c) = log(a + b + c)

We know that by property

log(a) + log(b) + log(c) = log(abc)

Therefore,

log(abc) = log(a + b + c)

Thus,

(abc) = (a + b + c)

Thus when a = b = c = 0,

then (abc) = (a + b + c)

0 = 0

and when a = 1, b = 2, c = 3,

then (abc) = (a + b + c)

(1 x 2 x 3 ) = (1 + 2 + 3)

6 = 6
