Answer:

x=6

Step-by-step explanation:

log(5x+10)-log(4x+12)=1-2log(3)

log(5x+10/4x+12)=1-2log(3)

log(5x+10/4x+12)=log(10)+log(3^-2)

log(5x+10/4x+12)=log(10×3^-2)

log(5x+10/4x+12)=log(10×1/9)

log(5x+10/4x+12)=log(10/9)

5x+10/4x+12=10/9

Tyler incorrectly says that the constant term of (x + 4)(x - 4) is zero.
a. What is the correct constant term?
b. What is Tyler's mistake? Explain your reasoning.

Answers

Answer:

a. -16 is the constant

b.if you expand the equation it would be x^2-16, and the constant is -16

Solving the expression (x + 4)(x - 4) ; the constant term in the expression is - 16 and not 0

To solve, we need to expand the expression : (x+4)(x-4)

Expanding the expression :

(x + 4)(x - 4)

Opening the bracket :

x² - 4x + 4x - 16

x² - 16

The constant term in the expression, is - 16 as it is the value without a variable.

Therefore, Tyler's mistake is incorrectly stating that the constant value is 0 instead of - 16

Answers

Answer:

B

Step-by-step explanation:

residual is the given - predicted

residual 1: -0.42

residual 2: 0.35

so on and so forth

B matches up with the first two coordinates

The residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

The residual = actual—predicted

We have given:

X         Given     Predicted     Residual value

1            0.7           0.28             0.42

2           2.3           1.95              0.35

3            4.1            4.18             -0.08

4           7.2           6.41              0.79

5            8             8.65            -0.65

Thus, the residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.

General admission to Paul’s Pumpkin Patch is $8.00. For children to ride the various rides, they must use tickets that cost $1.00 each. The number of tickets needed for each ride varies. The function for this situation is P(x) = x + 8, where P(x) represents total cost as a function of the number of tickets, x. What is the domain for visiting and riding rides at Paul’s Pumpkin Patch?
A. P(x) ≥ $8.00
B. x is all real numbers
C. x ≥ 0, where x is non-negative
D. x ≥ 0, x is an integer

Answers

Given:

Total cost P(x) as a function of the number of tickets, x is

[tex]P(x)=x+8[/tex]

To find:

The domain for visiting and riding rides at Paul’s Pumpkin Patch.

Solution:

Domain is the set of input values.

Here, domain is x and it represents the number of tickets.

We know that, number of tickets cannot be negative or decimal or fraction vales. So, x must be non-negative and integer value.

Domain = x ≥ 0, x is an integer

Therefore, the correct option is D.

pool is 16 feet, what is its width?

Answers

Answer:

8.75 feet

Step-by-step explanation:

Use the area formula, A = lw, where l is the length and w is the width

Plug in the area and length, and solve for w:

A = lw

140 = 16w

8.75 = w

So, the width is 8.75 feet

Answer:

8.75 ft

Step-by-step explanation:

Use the area formula, A = lw, where l is the length and w is the width

Plug in the area and length, and solve for w:

A = lw

140 = 16w

8.75 = w

So, the width is 8.75 feet
