Multiple RootsStep-by-step explanation:
Step 1: Define
x² = 625
Step 2: Solve for x
Square root both sides: x = ±25Step 3: Check
Plug in x into the original equation to verify it's a solution.
x = -25
Substitute in x: (-25)² = 625Exponents: 625 = 625Here we see that 625 does indeed equal 625.
∴ x = -25 is a solution to the equation.
x = 25
Substitute in x: 25² = 625Exponents: 625 = 625Here we see that 625 does indeed equal 625.
∴ x = 25 is a solution to the equation.

A bucket contains 40 red balls, 25 black balls, and 35 white balls. Two balls are drawn at random. What is the probability that the two balls are black and red?
Answer:
[tex]Probability = \frac{1}{5}[/tex] or [tex]Probability = 0.2[/tex]
Step-by-step explanation:
Given
[tex]Black = 25[/tex]
[tex]White = 35[/tex]
[tex]Red = 40[/tex]
Required
Determine the probability of selecting Black and Red
First, we need to calculate the number of red and black balls
The probability is calculated as thus:
[tex]Probability = P(Black\ and \ Red) \ or\ P(Red\ and \ Black)[/tex]
Convert to mathematical expressions
[tex]Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)][/tex]
Solve for each probaility;
[tex]P(Black) = \frac{Black}{Total} = \frac{25}{100}[/tex]
[tex]P(Red) = \frac{Red}{Total} = \frac{40}{100}[/tex]
So, we have:
[tex]Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)][/tex][tex]Probability = [\frac{25}{100} *\frac{40}{100}] + [\frac{40}{100} *\frac{25}{100}][/tex]
[tex]Probability = [\frac{1000}{10000}] + [\frac{1000}{10000}][/tex]
[tex]Probability = [\frac{1}{10}] + [\frac{1}{10}][/tex]
[tex]Probability = \frac{1+1}{10}[/tex]
[tex]Probability = \frac{2}{10}[/tex]
[tex]Probability = \frac{1}{5}[/tex]
or
[tex]Probability = 0.2[/tex]

Protease is an enzyme that breaks down proteins. What is the end product of this protein breakdown? A. amino acids B. fatty acids C.minerals D.vitamins
Answer:
A protease (also called a peptidase or ) is an enzyme an enzyme that catalyzes (increases the rate of) proteolysis, the breakdown of proteins into smaller polypeptides or single amino acids. They do this by cleaving the peptide bonproteins by hydrolysis, a reaction where water breaks bonds.

If the population of a certain county was 100,000 in 1998 and 110,429 in 2008, and if the formulay = P0ehtapplies to the growth of the county's population, estimate the population of the county in 2023. (P0 is the initial population. Round your value of h to four decimal places. Round your answer to the nearest whole number.)
Answer:
126807 people
Step-by-step explanation:
Given;
P= Poe^ht
Where;
P= population at time t
Po= population at the beginning
h= growth constant
t= time
1998- 2008 is ten years.
110429= 100,000e^10h
1.1 = e^10h
ln(1.1) = lne^10h
0.095 = 10h
h= 0.0095
In 2023, t = 25 years
P= 100,000e^(0.0095 × 25)
P= 126807 people

) Solve for x: –3(4x – 1) = –6(2x + 3)
Answer: there's no solution
Step-by-step explanation:
first, we remove the parenthesis.
-12x + 3 = -12x - 18
then, we cancel equal terms.
3 = -18
that doesn't work, so it makes a false statement.
no solution.

The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually
maintain a speed of three miles per hour while hiking. Write a statement that describes how the distance that you travel is
determined. Then identify the independent and dependent variables of this function.
a The distance traveled is three times the number of hours I have hiked. The independent variable
b. The distance traveled is three times the number of hours I have hiked. The independent variable
c. The hours I have hiked is three times the distance. The independent variable is distance. The
d. The hours I have hiked is three times the distance. The independent variable is hours. The
is hours. The dependent variable is distance.
is distance. The dependent variable is hours.
dependent variable is hours.
dependent variable is distance.
Please select the best answer from the choices provided
Answer:
If hours is represented as h, your distance is therefore 3*h (due to that for every hour, you walk 3 miles. For example, in one hour you'd walk 3 miles, in 2 hours you'd walk 3+3=3*2=6 miles,etc.). If distance is represented by d, we get 3*h=d. Since you have to figure out the distance from the equation (that's the purpose of it!), the distance is the dependent variable. In addition, since you can't have 2 separate variables in one equation, h is the independent variable due to that you have to put a number for h in to figure out the distance
So basically the answer is A.
