Step-by-step explanation:

$(7x)^x=7^{7^7}$

<u>log both sides:</u>

$log_7(7x)^x=log_7(7^{7^7})$
$xlog_7(7x)=7^7$
$x(1 +log_7x) = 7*7^6$
$x(1 +log_7x) = 7^6(1+6)$
$x(1 +log_7x) = 7^6(1+log_77^6)$

<u>Compare both sides to get:</u>

$x=7^6$

$x=117649$

GarryVolchara [31]

Bought : $65

60% Mark up.

60% of 65

(60/100) * 65

0.6 * 65

39.

Since this is a markup, the selling price = 65 + 39 = 104

Hence Selling Price = $104

Find the coordinates of the image of a triangle with vertices A(0, – 3), B(3, 0), and

lora16 [44]

Answer:

A'(-3,0), B'(0,-3) and C'(4,7)

Step-by-step explanation:

We are given that the vertices of triangle are A(0,-3), B(3,0) and C(-7,4).

We have to find the coordinates of the image of triangle under a rotation of 90° clockwise about the origin.

90° clockwise about the origin

Rule: $(x,y)\rightarrow (y,-x)$

Using the rule

The coordinates of A'

$A(0,-3)\rightarrow A'(-3,0)$

The coordinates of B'

$B(3,0)\rightarrow B'(0,-3)$

The coordinates of C'

$C(-7,4)\rightarrow C'(4,7)$

Hence, the vertices of image of triangle is given by

A'(-3,0), B'(0,-3) and C'(4,7)
