john and peter started jogging from the same place at the same time, but in opposite directions along a straight road. After jogging for 3 hours, they were 27 km apart. If john's average speed was 6 km/h, what is peters speed?
Answer: 3km/h
Step-by-step explanation:
Johns average speed was 6km/h, so in 3 hours he traveled 18 km. 27-18=9, so Peter ran 9 km in 3 hours. 9/3 = 3, so his average speed was 3km/h
Answer:
3 km/h
Step-by-step explanation:
Distance = speed x time
The distance apart equals to the sum of the distance that John jogged, and the distance that Peter jogged since they go opposite directions.
Hence,
let v be peter's speed
27 = 6x3 + vx3
27 = 18 + 3v
27-18 = 3v
9 = 3v
v = 9/3
v = 3 km/h

Answer:
A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers

if (14,25) and (9,-10) are two anchor points on a trend line, then find the equation of the line.
y = ?x - ?
Answer:
y= 7x-73
Step-by-step explanation:
the equation form is y=mx+c where m is the slope and c a constant
m= (25-(-10))/14-9 = 35/5 = 7
so y= 7x+c
replace x and y by 14 and 25 respectively
25 = 7*14+c
c= 25-7*14
c = -73
so y= 7x-73

Answer:
(a) y = -3/5 x + 13/5
(b) y = 5/3 x + 1/3
Step-by-step explanation:
(a) The slope of the tangent line is dy/dx. Use implicit differentiation:
x² + y² + 4x + 6y − 21 = 0
2x + 2y dy/dx + 4 + 6 dy/x = 0
2x + 4 + (2y + 6) dy/dx = 0
x + 2 + (y + 3) dy/dx = 0
(y + 3) dy/dx = -(x + 2)
dy/dx = -(x + 2) / (y + 3)
At the point (1, 2), the slope is:
dy/dx = -(1 + 2) / (2 + 3)
dy/dx = -3/5
Using point-slope form of a line:
y − 2 = -3/5 (x − 1)
Simplifying to slope-intercept form:
y − 2 = -3/5 x + 3/5
y = -3/5 x + 13/5
(b) The normal line is perpendicular to the tangent line, so its slope is 5/3. It also passes through the point (1, 2), so point-slope form of the line is:
y − 2 = 5/3 (x − 1)
Simplifying to slope-intercept form:
y − 2 = 5/3 x − 5/3
y = 5/3 x + 1/3
if 2x2 - 7x-15 is a factor of H(x):- 6x3 - 13x2 - ax - b where a and b are constants.
Find the values of a and b.
Find the zeros of H(X)
Answer:
1.) a = 73, b = 60
2.) H(0) = -60
Step-by-step explanation:
Since equation 2x2 - 7x - 15 is a factor of H(x) = 6x3 - 13x2 - ax - b where a and b are constants.
Find the root of 2x^2 - 7x - 15
2x^2 - 10x + 3x - 15 = 0
2x( x - 5 ) + 3( x - 5 ) = 0
2x + 3 = 0 or x - 5 = 0
2x = -3 or x = 5
X = -3/2 or 5
Substitute the two values into the H(x)
When x = - 3/2
6(-3/2)^3 - 13( -3/2 )^2 - a( -3/2 ) - b = 0
6(-27/8) - 13( 9/4 ) + 3a/2 -b = 0
-81/4 - 117/4 + 3a/2 - b = 0
- 198 + 6a - 4b = 0 .... (1)
When x = 5
6( 5 )^3 - 13( 5 )^2 - a(5) - b = 0
6(125) - 13(25) - 5a - b = 0
750 - 325 - 5a - b = 0
425 - 5a - b = 0 ..... ( 2)
Solve equation 1 and 2 simultaneously
Eliminate b
- 198 + 6a - 4b = 0 × 1
425 - 5a - b = 0 × 4
- 198 + 6a - 4b = 0
1700 - 20a - 4b = 0
- 1898 + 26a = 0
26a = 1898
a = 1898/26
a = 73
Substitute a back into equation 1
- 198 + 6(73) - 4b = 0
-198 + 438 - 4b = 0
4b = 240
b = 240/4
b = 60
2.) To Find the zeros of H(X), substitute 0 for x. that is,
H(0) = 6(0)^3 - 13(0)^2 - 73(0) - 60
H(0) = - 60

1. How much is it estimated that the United States population increased from July 1, 2000 to July 1, 2003? From July 1, 2003 to
July 1, 2007?
Answer:
2.92%
3.85%
Step-by-step explanation:
The population in 2000 is 282,194,308. The population in 2003 is 290,447,644. This is an increase of 8,253,336.
290,447,644 - 282,194,308 = 8,253,336
To find the percentage in increase, divide the difference by the original number and multiply by 100%. The population increased by 2.92%.
8,253,336/282,194,308 = 0.0292 × 100% = 2.92%
The population in 2003 is 290,447,644. The population in 2007 is 301,621,157. This is an increase of 11,173,513.
301,621,157 - 290,447,644 = 11,173,513
Divide the difference by the original number and multiply by 100%. The population increased by 3.85%.
11,173,513/290,447,644 = 0.0385 × 100% = 3.85%

A circle has a diameter of 20 mm what is it’s circumference? Use 3.14 for pi and do not round your answer
Answer:
The circumference of the circle is 62.8 mm.
Step-by-step explanation:
We must first know the formula for finding the circumference.
C = dπ
Let's plug in our diameter. We will use 3.14 for pi.
C = (20)(3.14)
Multiply the numbers together.
C = 62.8
So, the circumference of a circle with a diameter of 20 mm is 62.8 mm.
The circumference of a circle with the given diameter is 62.8 mm.
What is circumference of a circle?The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.
Given that, a circle has a diameter of 20 mm
So, radius = Diameter/2 = 10 mm
We know that, the circumference of a circle is of a circle is 2πr.
Now, circumference = 2×3.14×10
= 62.8 mm
Therefore, the circumference of a circle with the given diameter is 62.8 mm.

The length of a rectangle is 2 inches less than three times it’s width.and it’s perimeter is 36 inches .find the width of the rectangle. A. 5 in B .10 in C.4in
Answer:
A
Step-by-step explanation:
Let width =w in
Length = 3w - 2 in
Perimeter of rectangle = 36 inches
2* (length + width ) = 36
2*(3w -2 + w) = 36
2* (4w -2 ) = 36
2*4w - 2*2 = 36
8w - 4 = 36
Add 4 to both sides
8w - 4 + 4 = 36 +4
8w = 40
Divide both sides by 8
8w/8 = 40/8
w = 5
Width = 5 in

A principle of $2400 is invested at 7.5% interest, compounded annually. How many years will it take to accumulate $6000 or more in the account? Write the smallest possible whole number answer.
Step-by-step explanation:To find the interest accumulated over a period of time you use:
A = P [1 + (r/n)]^(nt)
with A = new amount in the account, P = principal, r = percent rate as a decimal, n = how many times you compound during one year, t = time in years.
A = 2000
P = 1500
r = 0.035
n=1
Thus you get:
2000 = 1500 (1+0.035)^t
Divide by 1500:
(4/3) = (1.035)^t
Apply "ln" on both sides:
ln(4/3) = t*ln(1.035)
Calculate the logarithms:
0.28768 = t*0.03440
Divide by 0.03440 on both sides:
t = 8.36 years
So after approximately 8 years and 5 month you will have $2000 or more in the account.
Is the relationship shown by the data linear? If so , model the data with an equation.
The data is linear.
The equation in slope intercept form is y = (-5/4)x - 53/4
The equation in standard form is 5x+4y = -53
========================================================
Explanation:
We know the data is linear because each time x increases by 4, the value of y decreases by 5. The slope is m = (change in y)/(change in x) = -5/4
Use m = -5/4 and one row of x,y values (say x = -9 and y = -2 from the first row) to find the value of b
y = mx+b
-2 = (-5/4)(-9) + b
-2 = 45/4 + b
45/4+b = -2
b = -2 - 45/4
b = -8/4 - 45/4
b = (-8 - 45)/4
b = -53/4
Therefore we go from y = mx+b to y = (-5/4)x - 53/4
We can convert to standard form like so
y = (-5/4)x - 53/4
4y = -5x - 53 ... multiply every term by 4
5x+4y = -53 ... add 5x to both sides
-----------------------
To check the answer, plug in x = -9 and you should get y = -2 as a result
y = (-5/4)x - 53/4
y = (-5/4)*(-9) - 53/4
y = 45/4 - 53/4
y = (45-53)/4
y = -8/4
y = -2
We have confirmed the first row of the table. The other rows will be handled the same way.
