On a coordinate plane, an exponential function has a horizontal asymptote of y = 0. The function curves up into the first quadra

aleksandr82 [10.1K]

Answer:

The graph will show an initial value that is lower on the y-axis

Step-by-step explanation:

The exponential function has the next general form:

$y = ab^x$

where a is the initial amount and b is the base.

If the a value in the function is decreased, but remains greater than 0, the y-intercept of the curve decrease.

Samuel bought 4 rolls of tape to seal boxes. Each roll contains 32.9 meters of tape. He uses 1 1/5 meters of this tape to seal e

Anestetic [448]

Answer:

109.33 boxes

Step-by-step explanation:

The first step is to calculate the total number of tape

= 32.9 × 4

= 131.6 m

Therefore the total number of boxes that Samuel will use to seal the boxes can be calculated as follows

= 131.6/ 1 1/5

= 131.6 ÷ 6/5

= 131.6 × 5/6

= 658/6

= 109.33 boxes

The estimate regression equation for a model involving two independent variables and 10 observations follows.

True [87]

Answer:

a) $b_1 = 0.5906\\b_2 = 0.4980$

b) y = 289.815

Step-by-step explanation:

We are given the following information:

The estimate regression equation for a model involving two independent variables and 10 observations follows:

$y = 29.1270 + 0.5906x_1 + 0.4980x_2$

where $x_1, x_2$ are the two independent variable and y is the dependent variable.

a) The regression line is of the form:

$y = b_0 + b_1x_1 + b_2x_2\\\text{where } b_0 \text{ is the y-intercept and }b_1, b_2\text{ are the coefficients of} x_1, x_2\text{ respectively}$

Comparing, we get,

$b_1 = 0.5906\\b_2 = 0.4980$

These are the coefficients of $x_1, x_2$ respectively, and helps us to know the the significance of the independent variable in predicting the independent variable.

b) We have to estimate y when

$x_1 = 180 \text{ and } x_2 = 310\\y = 29.1270 + 0.5906x_1 + 0.4980x_2\\\text{Putting values}\\y = 29.1270 + 0.5906(180) + 0.4980(320)\\y = 289.815$
