What is the range of y = log Subscript 8 Baseline x?
jeka94

The range of y =\log_8(x) is the set of all real values

<h3>How to determine the range?</h3>

The function is given as:

y =\log_8(x)

The above function is a parent logarithmic function.

The parent logarithmic function have a range of the set of all real values

Hence, the range of y =\log_8(x) is the set of all real values

If you vertically compress the square root parent function f(x) = ^x, by 1/2 of a unit what is the equation of the new function
Naddik [55]

Answer:

The equation of the new function is g(x) = \frac{\sqrt{x}}{2}

Step-by-step explanation:

Suppose we have a function f(x).

a*f(x), a > 1, is vertically stretching f(x) a units. Otherwise, if a < 1, we are vertically compressing f(x) by a units.

f(x - a) is shifting f(x) a units to the right.

f(x + a) is shifting f(x) a units to the left

In this question:

f(x) = \sqrt{x}

Vertically compressing by 1/2:

This is the same as multiplying the function by 1/2. So

\frac{1}{2} \times \sqrt{x} = \frac{\sqrt{x}}{2}

The equation of the new function is g(x) = \frac{\sqrt{x}}{2}

The average weight of full-grown beef cows is 1,470 pounds with a standard deviation of 230 pounds. if the weights are normally
creativ13 [48]

Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. \mu= 1470 ,  \sigma = 230, x=1750

The relationship between z score, mean and standard deviation is given by

x = \mu+z\sigma

So the z value according to this is given by the formula

1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile

A merchant mixed 15 Ib of a cinnamon tea with 10 Ib of spice tea. The 25-pound mixture sells for $65. A second mixture included
sertanlavr [38]

Answer:

Step-by-step explanation:

12 x + 4 y = 42 .............1

16 x + 8 y = 64 .............2

Eliminate y

multiply (1)by -2

Multiply (2) by 1

-24 x -8 y = -84

16 x 8 y = 64

Add the two equations

-8 x = -20
