Answer:

$log_{3}4 +6log_{3} {x}+log_{3} y$

Step-by-step explanation:

Mistake $6log_3(4xy)$

Correct expansion would be as given below:

$log_{3}(4 {x}^{6}y ) \\ \\ = log_{3}4 +log_{3} {x}^{6} +log_{3} y \\ \\ = log_{3}4 +6log_{3} {x}+log_{3} y \\$

Answer:

y = 21

Step-by-step explanation:

In straightforward fashion, we can find the midpoints of the two segments, and set the distance between them equal to 10.

M = midpoint of AB

M = (A+B)/2 = ((-1, 0) +(-3, 6))/2 = (-4, 6)/2 = (-2, 3)

N = midpoint of CD

N = (C+D)/2 = ((3, 1) +(5, y))/2 = (8, 1+y)/2 = (4, (1+y)/2)

Then the distance MN is given by the distance formula.

|N-M| = 10 = √((4 -(-2))² +((1+y)/2 -3)²) . . . . . distance formula*

100 = 36 +((1+y)/2 -3)² . . . . . square both sides

64 = ((1 +y)/2 -3)² . . . . . . . . . subtract 36

8 = (1 +y)/2 -3 . . . . . . . . . . . . (positive) square root

11 = 1+y/2 . . . . . . . . add 3

22 = 1+y . . . . . . . . . multiply by 2

21 = y . . . . . . . . . . . subtract 1

_____

* The distance formula is an application of the Pythagorean theorem. Basically, the differences of x- and y-coordinates are taken to be the legs of a right triangle. They length of the hypotenuse is the distance between the two points.

d² = (x2 -x1)² +(y2 -y1)² . . . . . . . from the Pythagorean theorem

d = √((x2 -x1)² +(y2 -y1)²) . . . . . the usual distance formula

PLEASE ANSWER ILL GIVE YOU BRIANLIEST

MariettaO [177]

Answer:

y-intercept = -2

x-intercept = -4

Step-by-step explanation:

y-intercept is the point where x = 0. Hence,

y-intercept = -2

x-intercept us the point where y = 0. Hence,

x-intercept = -4

$\rule[225]{225}{2}$

Hope this helped!

A two-pound bag of assorted candy contained 100 caramels, 83 mint patties, 93 chocolate squares, 80 nut clusters, and 79 peanut

faltersainse [42]

Answer:

The degree measure of the slice representing the mint patties rounded to the nearest degree is 69°.

Step-by-step explanation:

Consider the provided information.

A two-pound bag of assorted candy contained 100 caramels,

83 mint patties,

93 chocolate squares,

80 nut clusters,

79 peanut butter taffy pieces.

Now find the degree measure of the slice representing the mint patties rounded to the nearest degree as shown:

$\frac{83}{100+83+93+80+79} \times 360^0$

$\frac{83}{435} \times 360^0$

$68.69\approx69^0$

Hence, the degree measure of the slice representing the mint patties rounded to the nearest degree is 69°.
