Final answer:
0.64 is a finite decimal with zero repeating digits as it does not have digits that continue infinitely after the decimal.
Explanation:
The number 0.64 is a decimal that has two digits after the decimal point. These digits (6 and 4) do not repeat infinitely, making them non-repeating decimal digits. Therefore, there are zero repeating digits in 0.64. A repeating decimal would have one or more digits after the decimal point that continue infinitely, often denoted by a bar over the repeating digits. Since 0.64 does not exhibit this pattern, it is a finite decimal.

Solve this question using simultaneous equations.
To cover a distance of 10 km, Jacob runs some of the way at 15 km/h, and walks the rest of the way at 5 km/h. His total journey time is 1 hour. How far did Jacob run?
Answer: Jacob ran for half an hour, and walked for the remaining half an hour. 15 km/hr x 0.5 hr = 7.5 km running, and 5km/ hr x 0.5 hr=2.5 km walking
Step-by-step explanation:
Let x hours be the time Jacob ran, and therefore for 1-x hours he walked.
time x speed= distance
we get, 15x + 5*(1-x)=10
15x+5-5x=10,
10x=5,
x=0.5 hours.
Average speed was 10km/h.
HOPE THIS HELPS.
Jacob ran 7.5 km at a speed of 15 km/h. By setting up a system of simultaneous equations, we found the distances for both running and walking that add up to the total distance of 10 km, while also fulfilling the constraint of a 1-hour total journey time.
To solve this problem with simultaneous equations, let's define two variables for the two different parts of the journey: x for the distance Jacob runs at 15 km/h and y for the distance he walks at 5 km/h. We know that Jacob covers a total distance of 10 km and the total time taken for the journey is 1 hour.
Set up the equations:
Equation for the distance: x + y = 10
Equation for the time: (x/15) + (y/5) = 1 (Since time is distance divided by speed)
Solve these equations simultaneously.
Multiply the second equation by 15 to clear the denominators: x + 3y = 15
Subtract the first equation from this new equation to solve for y: 2y = 5, so y = 2.5 km.
Substitute y back into the first equation to find x: x = 10 - 2.5, so x = 7.5 km.
Jacob ran 7.5 km at 15 km/h.
Check the answer:
Is 7.5 km in 1 hour at 15 km/h reasonable? Yes, because 15 km/h means he would run 15 km in 1 hour, so running for less than an hour for 7.5 km is plausible.

The given line segment has a midpoint at (3, 1).
What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?
y = x
y = x – 2
y = 3x
y = 3x − 8
Answer:
y = 1/3 x.
Step-by-step explanation:
The slope of the given line is
(4 - (-2) / 2 - 4)
= -3.
So the slope of the line perpendicular to it = -1 / (-3) = 1/3.
This line also passes through the point (3, 1) so its equation is ( by the point-slope form):
y - 1 = 1/3(x - 3)
y - 1 = 1/3x - 1
y = 1/3 x (answer).
Answer: The answer is y= x/3
Step-by-step explanation:
Given points =(2,4) and (4,-2) whose mid point is (3,1)
Let the points be named as A(2,4) and B(4,-2) and mid point as C(3,1)
So slope of AB = [tex]\frac{4-(-2)}{2-4}[/tex]
=[tex]\frac{6}{-2}[/tex]
= -3
We know that Product of Slope of perpendicular lines = -1
Now slope of the line perpendicular to AB × slope of AB = -1
-3 × m2 =-1
i.e. m2 =[tex]\frac{1}{3}[/tex]
Now equation of perpendicular bisector of AB passing through C(3,1) is
[tex]y -1 =\frac{1}{3}(x-3)\\[/tex]
[tex]y= 1+\frac{1}{3}x -1[/tex]
[tex]y=\frac{1}{3}x[/tex]
Hence the equation of line is y =x/3
Solve the equation 2 = -6 – 20x for x.

C. 2/5
D. 5/2
Answer: - 2/5
Step-by-step explanation: Isolate the vcariable by divding each side by factors that don't contain the variable.
Exact Form: x = - 2/5
Deciaml form: x = -0.4
Hope this helps! :) ~Zane
Hello there! B. -2/5.
To solve for x, you want to get x alone and isolate all other terms.
2 = -6 – 20x - Start by adding 6 to both sides of the equation.
2+6 = -6+6 – 20x ⇒ 8 = -20x
8 = -20x - Next, divide both sides of the equation by -20..
8/-20 = -20/-20x ⇒ -8/20 = x
Now, we have -8/20 as our value for x. The last step is to simplify. Since 8 and 20 are both divisible by 4, divide both sides of the fraction by 4.
x = -2/5. This is your final answer. I hope this helps and have a great day! ~ saturns

Find the average rate of change between f(-7) and f(-1) in the function f(x)=x^2+2x -8
Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here [ a, b ] = [ - 7, - 1 ]
f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9
f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27
Hence
average rate of change = [tex]\frac{-9-27}{-1-(-7)}[/tex] = [tex]\frac{-36}{6}[/tex] = - 6

the drop downs for the first four are either 50
100
200
300
And the last two are either
faster than
slower than
the same speed as
Answer:
See explanation
Step-by-step explanation:
Car A: Started at 0 and ended at 300, thus, car A travels 300 miles.
It travels 6 hours, so car A speed is [tex]\frac{300}{6}=50[/tex] mph.
Car B: Started at 100 and ended at 300, thus, car B travels 300-100=200 miles.
It travels 5 hours, so car B speed is [tex]\frac{200}{5}=40[/tex] mph.
Since 50>40, car A traveled faster than car B.
The graph for the car A is steeper than the graph for the car B.

How do I do this question?
Check the picture below.
now, based on the provided information, we know the hexagon and triangle are regular polygons, equal sides and equal angles, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.
now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.
if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a full revolution will be 360°, so the remaining angle in green there must be 360° - 120° - 136° = 104°, and her twin at vertex J is also 104°.

Suppose that F(x) =x^3 and G(x) =-5x^3. Which statement best compares the graph of g(x) with the graph of f(x)?
The statement that best compares the graph of g(x) = -5x³ with the graph of f(x) = x³ is that the graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."
Option D is the correct answer.
We have,
Reflection across the x-axis:
The negative coefficient of -5 in g(x) reflects the graph across the x-axis compared to f(x).
This means that the points on the graph of g(x) will have the same
x-coordinates as the corresponding points on the graph of f(x) but will have opposite y-coordinates.
Vertical stretching by a factor of 5:
The absolute value of the coefficient (-5) in g(x) indicates that the graph is vertically stretched by a factor of 5 compared to f(x).
This means that for any given x-value, the corresponding y-value on the graph of g(x) will be five times larger (or smaller, depending on the sign) than the corresponding y-value on the graph of f(x).
Thus,
The graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."

Putting money in a bank and earning interest
Step-by-step explanation:
This problem can be used in real life to describe when you put money in a bank, in this case, it could be two dollars, and leave it there for x amount of years, then taking it out after an amount of years and checking what you have. Since this is a linear equation, your money doesn't go up exponentially. It'll keep going up the same rate for the whole time until you decide to take it out. Here's an example of what it'll look like, if it helps:
Before interest: You put in $2First year: You have $5.18 in the bankSecond year: $8.36Third year: $11.54Your money keeps going up. Hope this helps!
Final answer:
A real world situation for the function f(x) = 3(1.06x) + 2 could be a situation where a person is investing money in a savings account. The function represents the balance in the account after a certain amount of time (x years) with an interest rate of 6%.
Explanation:
A real world situation for the function f(x) = 3(1.06x) + 2 could be a situation where a person is investing money in a savings account. Let's say the initial amount of money deposited in the account is $2. The function represents the balance in the account after a certain amount of time (x years) with an interest rate of 6%. The key features of the function are:
3: This represents the multiplier of the initial investment, indicating that the account balance increases by three times the amount of the initial investment.
1.06: This represents the growth factor due to the 6% interest rate. It is multiplied by the current balance each year.
2: This represents the $2 initial deposit in the account.
