Answer:

One: x =  3/32

Two: y =  3/10

Step-by-step explanation:

One

y = k*x

1/4 = k* 1/8                    Multiply both sides by 8

8(1/4) = 8*k*(1/8)

8/4 = k

k = 2

=======================

3/16 = 2*x                      Divide by 2

3/32 = x

Two

y = 2/5

x = 1/3

2/5 = k * 1/3                   Multiply both sides by 5

2 = 5*k * 1/3

2 = 5/3 * k                     Multiply both sides by 3

6 = 5 * k                        Divide both sides by 5

6/5 = k

y = 6/5 * x

x = 1/4

y = 6/5 * 1/4

y = 6/20 = 3/10

Given a quadratic function in vertex form:
Alja [10]

Answer:

See below

Step-by-step explanation:

<u>Part A</u>

A vertical stretch takes place when a\cdot f(x) given that  |a| > 1

<u>Part B</u>

A vertical compression takes place when a\cdot f(x) given that 0 < |a| < 1

<u>Part C</u>

A vertical stretch is different than a horizontal compression:

  • In a vertical stretch, the input stays the same, but the output is multiplied by the scale factor
  • In a horizontal compression, the output stays the same, but the input is multiplied by the scale factor

<u>Part D</u>

A reflection across the x-axis means that the output, our y-variable, is the opposite sign. This means that all values of a must be negative such that a\cdot f(x) as mentioned in parts A and B. Also, in part C, since our scale factor is negative, the output is the only one being multiplied by the scale factor.

Each of the statements contains a blunder. In each case, choose the statement that correctly explains the blunder. (a) "There is
Vikki [24]

Answer:

Correlation requires both variables to be quantitative.

Step-by-step explanation:

The correlation coefficient measures the strength of relationship between two quantitative variables. In the given scenario correlation between sex of American workers and their income is computed and indicated that there is a high correlation between them. The sex of American worker is a categorical variable or a qualitative variable while income of American worker is a quantitative variable. The correlation between a quantitative variable and a qualitative variable can't be computed. So, the statement explains the blunder in the given scenario is "Correlation requires both variables to be quantitative".

Please can you help me I don't understand
Alexxx [7]
I will show you how to do the first one.....we are finding the GCF...the largest number that goes into each number (same for variables)

1.)  20yx , 80x³  ( factor each number and variable)

20  =  2, 4, 5, 10, 20
y    =  y
x     =  x
80  =  2, 4, 5, 8, 10, 16, 20, 40, 80
x³  =  x, x, x

what is the largest number that 20 and 80 have in common?    20...
how about the variables?    x

so, the Greatest Common Factor (GCF is 20x)

Simplify this expression: cos t(sec t − cos t)
Nostrana [21]
\cos t \, (\sec t - \cos t)
= \cos t \, (\frac{1}{\cos t} - \cos t)
= 1 - \cos^2 t
= \bf sin^2 t
