Solve x2+8x-10=0 by completing the square. What are the solutions? *answer choices are in the picture
Answer:
Last option
Step-by-step explanation:
Step 1: Write out equation
x² + 8x - 10 = 0
Step 2: Add 10 to both sides
x² + 8x = 10
Step 3: Complete the Square
x² + 8x + 16 = 10 + 16
(x + 4)² = 26
Step 4: Square root both sides
x + 4 = ±√26
Step 5: Subtract 4 on both sides
x = -4 ± √26

8 x 10^4 is how many times as large as 4 x 10^-5
Answer:
2 x 10^9
Step-by-step explanation:
There 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.
For example 4/2 = 2
We have to determine 8 × 10⁴ is how many times as large as 4 × 10⁻⁵
Apply the division operation to get
⇒ 8 × 10⁴ ÷ 4 × 10⁻⁵
⇒ (8 × 10⁴) / (4 × 10⁻⁵)
Reduce the term of the numerator
⇒ ( 10⁴) / (10⁻⁵)
⇒ ( 10⁴) × (10⁵)
⇒ ( 10⁴⁺⁵)
⇒ 10⁹
Hence, there 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.

Answer:
[tex]\huge\boxed{\text{(A)}\ 0.36}[/tex]
Step-by-step explanation:
This sequence will have a pattern. Our goal is to try and find this pattern.
Our first two numbers are -45 and 9. The first relationship between these numbers that pops into my mind is 5. [tex]9 \cdot 5 = 45[/tex]. However, we go from -45 to 9. This means we have to divide by -5. [tex]-45 \div -5 = 9[/tex]
Let's check this actually is what the sequence is. It would be true if [tex]9 \div -5 = -1.8[/tex].
[tex]9 \div -5 = -1.8[/tex]
So -5 is the divisor.
To find the next term in the sequence, we divide -1.8 by -5.
[tex]-1.8 \div -5 = 0.36[/tex]

Savannah can run 1/2 mile in 300 seconds. What is
Savannah's unit rate?
10 mile per minute
2 1/2 mile per minutes
2/5 mile per minutes
1/10 mile per minute
The required unit rate of the Savannah run is given as 1/10 mile per minute. Option D is correct.
What is the unit rate?A unit rate is a rate in which the second term is 1. In other words, a unit rate is a rate that compares two quantities, with the second quantity being expressed as 1. Unit rates are often used to express a rate per unit of measurements, such as price per item, speed per hour, or cost per pound.
here,
As given in the question Savannah can run 1/2 mile in 300 seconds to evaluate the unit rate we must convert the time given second in minutes by dividing it by 60,
300 seconds = 300/60 = 5 minutes
Now,
Unit rate = 1/2 mile: 5 minutes
Unite rate = 1/10 mile per minute
Thus, the required unit rate of the Savannah run is given as 1/10 mile per minute. Option D is correct.

Answer:

Step-by-step explanation:
Three girls-- Kali, Annie, and Xiaoling -- go on a trip with their youth orchestra. The three girls share the cost of the hotel. The bill comes to $295.48. It includes $13.25 for some food that Annie orders and $14.00 for cleaning Xiaoling's uniform. What is the dollar amount of each girl's share of the hotel bill?
Answer:
About $107.57
Step-by-step explanation:
if you add up the bill cost and the 13.25 for the food and 14.00 for cleaning Xialing's uniform its $322.73 divide that between the 3 girls and you get about 107.57
Each girl would pay Kali = $89.41
Annie = $102.66
Xiaoling = $103.41
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
Foe example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Total bill amount = $295.48
Now, the amount excluding the amount of food ordered by Annie
= 295.48 - 13.25
= $282.23
and, the amount excluding Cleaning amount
= 282. 23 - 14
= $268.23
So, Each Girl would pay
Kali = $ 268.23 / 3 = $89.41
Annie = 89.41 + 13.25 = $102.66
Xiaoling = 89.41 + 14 = $103.41

Which equation would you use to find x?
Write the equation g(x) of the transformation of the parent graph f(x) = |x| stretched horizontally by a factor of 3.
Answer:
g(x) = |1/3x|
Step-by-step explanation:
f(x) = |x|
y = f(Cx) 0 < C < 1 stretches it in the x-direction
g(x) = |1/3x|
We can start with: f(x) = |x|
0 < c < 1 means x-direction stretch
y = f(cx)
3 unit horizontal stretch
After: g(x) = |1/3x|
Best of Luck!
