Step-by-step explanation:
Hope it's help, study well goodluck
By solving the given Equation (x+8)² - 2 = 0 we get the Value from lesser x = -9.41 and greater x = -6.59
To solve the Equation (x+8)² - 2 = 0 and find the values of x,
Step 1: Expand the equation
(x+8)² - 2 = 0
(x+8)(x+8) - 2 = 0
(x² + 16x + 64) - 2 = 0
x² + 16x + 62 = 0
Step 2: Set the equation equal to zero and rearrange
x² + 16x + 62 = 0
Step 3: Use the quadratic formula
The quadratic formula states that for an equation in the form ax² + bx + c = 0, the solutions for x can be found using the formula:
x = (-b ± √(b² - 4ac)) / (2a)
In our equation, a = 1, b = 16, and c = 62.
Substituting these values into the quadratic formula, we get:
x = (-16 ± √(16² - 4(1)(62))) / (2(1))
x = (-16 ± √(256 - 248)) / 2
x = (-16 ± √8) / 2
Step 4: Simplify the square root
√8 can be simplified as follows:
√8 = √(4 × 2)
= √4 × √2
= 2√2
Substituting this into our equation:
x = (-16 ± 2√2) / 2
Step 5: Simplify further
We can simplify the expression by dividing both the numerator and denominator by 2:
x = -8 ± √2
So the solutions for x are -8 + √2 and -8 - √2.
Rounding to two decimal places, the solutions are approximately:
lesser x = -8 - √2 ≈ -9.41
greater x = -8 + √2 ≈ -6.59
Therefore, the solutions for x, from least to greatest (rounded to two decimal places), are -9.41 and -6.59.

in a hypothesis test, if the computed p-value is less than 0.001, there is very strong evidence to
Answers
Answer: reject the null hypothesis
Explanation:
If the p-value is smaller than the significance level alpha, then we reject the null. You can think of the p-value being the probability that the null is correct. If the p-value is below a certain threshold (the significance level), then we can be fairly confident that rejecting the null is a good decision.
Your teacher or textbook might have brought up the phrase "If the p-value is low, then the null must go" as a way to help remember this rule. If the alpha level isn't stated, then usually it defaults to 0.05
A tortoise moves at a speed of 34 inches in 11 seconds. What is its average speed in feet per hour?
Answers
Answer:
927.3 feet per hour
Step-by-step explanation:
first determine how many seconds are in one hour
there are 60 seconds in one minute and 60 minutes in one hour
so there are 60x60, or 3600 seconds in one hour
now you can create a proportion of inches/seconds = inches/seconds
let 'x' = inches per hour
34/11 = x/3600
cross-multiply to get:
11x = 3600x34
11x = 122,400
x = 122,400/11
x = 11,127.3 inches per hour
to determine how many feet per hour you must divide 11,127.3 inches by 12
this equals 927.3 feet per hour

A painter ordered 3 gallons of red paint for $35 per gallon. He ordered 5 gallons of blue paint for $39 per gallon. What is the total cost of both kinds of paint?
Answers
Answer:
$300 is the total cost for both kinds of paint
Step-by-step explanation:
1) Start by breaking down the problem so it was more simple
- Red paint is $35 per gallon; blue is $39 per gallon
2) Since it is by gallon, you will multiply the number of gallons by the cost for each to get the total cost of each
- 35 * 3 = $105 for 3 gallons of red paint
- 39 * 5 = $195 for 5 gallons of blue paint
3) Total cost together; you will add the total cost of red and blue paint together
- 105 + 195 = $300
