Answer:

Step-by-step explanation:

This is a piecewise function.

Since the value being asked to evaluate is -6, choose the part of the function that is applicable.

You would focus on $x\geq -6$ since you were given a -6 to evaluate.

Then use the expression that describes the function at that location.

$x^{2} - 1$

Plug in your value of -6

$(-6)^{2}-1\\ 36-1\\35$

Divide 40x/64y by 5x/8y.

Lemur [1.5K]

Answer:

The correct answer option is C. 1.

Step-by-step explanation:

We are to divide $\frac { 4 0 x } { 6 4 y }$ by $\frac { 5 x } { 8 y }$ .

Rewriting them as a fraction in whole:

$\frac { \frac { 4 0 x } { 6 4 y } } {\frac { 5 x } { 8 y } }$

Changing the division into multiplication by taking the reciprocal of the fraction in the denominator to get:

$\frac { 4 0 x } { 6 4 y }$ × $\frac{8y}{5x}$

Cancelling out the like terms to get:

The following scatter plot represents the number of views a video gets each day.

N76 [4]

Answer:

y = 1.0535(4.9512)^x

It can be considered a viral video

Step-by-step explanation:

Using the exponential regression calculator, the regression model obtained is :

y = 1.0535(4.9512)^x

Using the model, we can determine if a video can be considered viral ;

Number of days, x = 10

y = 1.0535(4.9512)^10

y = 1.0535(8853290.1338)

y = 9,326,941.15

Hence, video will receive way over 3 million reviews, a review of about 9,326,941, hence, it can be considered a viral video.
