The San Francisco half-marathon is a 13.6-mile race that travels up and down the hills of San Francisco. One street, Folsom Street, has a slope that can be represented by the function 2y=4x+7. Another street, Divisadero Street, has a slope that can be represented by the function 5y = 2x +9.
Which of these hills would you rather run-up? Why? Use evidence to support your answer.
Answer:
Step-by-step explanation:
Ok, from what I just reviewed, once you get the equation into the form of y = mx + b, the m is the slope of a line.
So take the first street, Folsom
2y = 4x + 7
y = 2x + 7/2
the slope is 2.
The second street, Divisadero
5y = 2x + 9
y = 2/5x + 9/5
the slope is 2/5.
So whether we're talking about 2/5 of an inch, 2/5 of a foot, or 2/5 of a mile, 2/5 is less than 2, so I would rather go up the less steep road...Divisadero.

What function represents the pattern shown in the table?
Given:
The table of values of an exponential function.
To find:
The function for the given table of values.
Solution:
The general exponential function is:
[tex]y=ab^x[/tex] ...(i)
Where, a is the initial value and b is growth factor.
From the given table it is clear that the function passes through the points (1,9) and (2,36). It means the function must be true for these two points.
[tex]9=ab^1[/tex] ...(ii)
[tex]36=ab^2[/tex] ...(iii)
On dividing (iii) by (ii), we get
[tex]\dfrac{36}{9}=\dfrac{ab^2}{ab}[/tex]
[tex]4=b[/tex]
Putting [tex]b=4[/tex] in (ii), we get
[tex]9=a(4)^1[/tex]
[tex]\dfrac{9}{4}=a[/tex]
Putting [tex]a=\dfrac{9}{4},b=4[/tex] in (i), we get
[tex]y=\dfrac{9}{4}(4)^x[/tex]
[tex]y=9(4)^{x-1}[/tex]
The function notation with variable n is:
[tex]f(n)=9(4)^{n-1}[/tex]
Therefore, the correct option is D.

Step-by-step explanation:
The diameter of a circle is 4cm. Find it area to nearewt tenth.
Answer:
12.6cm
Step-by-step explanation:
12.6 cm²
Area formula: (A = πr²)
If the diameter is 4 cm.. then that would mean the radius is 2 cm because the radius is half of the diameter. So, we already know the radius.. we just have to find the circumference.
Circumference formula: (C = πd) or (C = 2πr)
Finding the circumference : 3.14 × 4 = 12.56 cm
So, we now have the radius and circumference.
Radius = 2 cm
Circumference = 12.56 cm
Finding the Area : 3.14 × 2 × 2 = 12.56 cm²
So, 12.56 rounded to the nearest tenth is 12.6 cm².

which group has a larger median number of bones discovered?
Answer:
Group A has a larger median
Step-by-step explanation:
Group A : 0,1,2,3,3,3,4,4,5,5,7,7,8,9,9
Group B : 0,1,1,1,1,2,2,2,3,3,3,5,,6,6,7,8,8,9,9,9
You cross the first number out then you cross the last number. You continue that pattern until you have one or two digits left. If you have two digits left, you add them then divide by two. That the median. But, if you only have one digit, that number is the median.

A line passes through the point (3,3) and is parallel to the line given by the equation Y=-2/3x - 2
What is the equation of the line?
A. Y=3/2x
B. Y=-2/3x+5
C. Y=2/3x-5
D. Y=-3/2x+1
Answer:
B. [tex]y=-\frac{2}{3}x+5[/tex]
Step-by-step explanation:
Equation of a line: y=mx+b (Where m is the slope and b is the y- intercept)
Parallel lines have the same slope.
So that means that the line will have the slope [tex]-\frac{2}{3}[/tex].
So we can write the equation of the line as y= -2/3x+b
Since it goes through the point (3,3) we can plug in 3 for x and y by doing:
[tex]y=-\frac{2}{3} x+b\\3=-\frac{2}{3} (3)+b\\3=-2+b\\b=5[/tex]
Now we know the y intercept (b) we can write the equation of the line.
[tex]y=-\frac{2}{3}x+5[/tex]
The equation of the line would be equal to y= -2/3x + 5
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
The Equation of a line: y=mx+b
Where m is the slope and b is the y- intercept
Since Parallel lines have the same slope.
So we can write the equation of the line as;
y= -2/3x+b
Since it goes through the point (3,3) we can plug in 3 for x and y
y= -2/3x+b
3 = -2 + b
b = 5
Now we know the y intercept (b) we can write the equation of the line.
y= -2/3x + 5

The volume of this cylinder is 16,328 cubic millimeters. What is the height?
Answer: 13
Step-by-step explanation:
Answer:
Step-by-step explanation:
Givens
r = 20 mm
Volume = 16328
h = ?
Formula
V = pi * r^2 * h
Solution
16328 = 3.14 * 20^2 * h
16328 = 3.14 * 400 * h
h = 16328/(3.14 * 400)
h = 16328 / 1256
h = 13

write 0.001574 in scientific notation
Answer: 1.574 × 10-3
Step-by-step explanation:
To convert 0.001574 into scientific notation, follow these steps:
Move the decimal 3 times to right in the number so that the resulting number, m = 1.574, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -3
Write in the scientific notation form, m × 10n
= 1.574 × 10-3
Answer:
0.001574 in scientific notation is 1.574 × 10^-3
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.001574 into scientific notation, follow these steps:
Move the decimal 3 times to right in the number so that the resulting number, m = 1.574, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -3
Write in the scientific notation form, m × 10n
= 1.574 × 10^-3
Therefore, the decimal number 0.001574 written in scientific notation is 1.574 × 10^-3 and it has 4 significant figures.

Where x is the number of weeks.
To find:
The population after 4 weeks.
Solution:
The population of insect after x weeks is given by:
[tex]f(x)=10(2)^x[/tex]
We need to find the population after 4 weeks.
After substituting [tex]x=4[/tex], we get

Lauren studies for 3 \frac{1}{3} 3 1 hours. She took a break every \frac{2}{3 } 3 2 hour. HOW MANY breaks did she take?
Answer: 5 times
Step-by-step explanation:
Your question isn't well written but let me rewrite it based on what I believe that you wrote.
Lauren studies for 3 1/3 hours. She took a break every 2/3 hour. How many breaks did she take?
To solve the question, we have to divide the number if hours used in studying by the interval used in taking a break. This will be:
= 3 1/3 ÷ 2/3
= 10/3 / 2/3
= 10/3 × 3/2
= 5
She took a break 5 times

A circular pizza has a diameter of 16 inches. Each slice of pizza has a central of angle 45°. What is the area of each slice of pizza?
A. 3.1 in²
B. 6.13 in²
C.25.1 in²
D. 100.5 in²
Answer:
First, let's find the area of the whole pizza:
Area of circle = pi x r^2
r = 16 / 2
r = 8
Area of pizza = pi x 8^2 = 64pi
Now 45 degrees is 1/8 of the whole pizza (it is one-eighth of 360 degrees), and so a slice is proportional to the fraction of the area:
64pi / 8 = 8pi
The area of each slice is then 8pi in.^2

How many 2-liter bottles of soda will you need to fill ten 500 milliliter containers?
Answer:
2.5 bottles
Step-by-step explanation:
10 * 500 ml = 5000 ml
5000 ml = 5 l
5/2 = 2.5
2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.
How many milliliters in 1 liter?A liter is a cubic meter unit of volume which is equal to 1000 cubic centimeters.
1 liter = 1000 milliliters
Ten 500 milliliter containers
10 × 500 ml = 5000 ml
5000 ml = 5 l
