Bob runs four laps. The average speed for the first lap is 12 km/h, the average speed for the second lap is 10km/h, the average speed for the third lap is 8km/h and the average speed for the last lap is 6km/h. What is average speed for the four laps
Answer:
The average speed for the four laps is 9 km/h.
Step-by-step explanation:
The average speed of the four laps can be calculated as follows:
[tex] \overline{v_{T}} = \frac{\overline{v_{1}} + \overline{v_{2}} + \overline{v_{3}} + \overline{v_{4}}}{4} [/tex]
Where:
[tex]\overline{v_{1}}[/tex]: is the average speed for the first lap
[tex]\overline{v_{2}}[/tex]: is the average speed for the second lap
[tex]\overline{v_{3}}[/tex]: is the average speed for the third lap
[tex]\overline{v_{4}}[/tex]: is the average speed for the fourth lap
Hence, the average speed for the four laps is:
[tex] \overline{v_{T}} = \frac{12 km/h + 10 km/h + 8 km/h + 6 km/h}{4} [/tex]
[tex] \overline{v_{T}} = 9 km/h [/tex]
Therefore, the average speed for the four laps is 9 km/h.
I hope it helps you!
Use the diagram to find the angle measures of the triangle. Recall that the sum of the angle measures of a triangle is 180°
x°=
(x+5)°=
5X°=
Answer:
[tex] \boxed{ \bold{ \sf{x = 25°}}}[/tex]
[tex] \boxed{ \bold{ \sf{(x + 5) = 30°}}}[/tex]
[tex] \boxed{ \bold{ \sf{5x = 125°}}}[/tex]
Step-by-step explanation:
We know that sum of angle of triangle adds up to 180°
Finding the value of x
[tex] \sf{5x + x + x + 5 = 180°}[/tex]
Collect like terms
⇒[tex] \sf{7x + 5 = 180}[/tex]
Move 5 to right hand side and change its sign
⇒[tex] \sf{7x = 180 - 5}[/tex]
Subtract 5 from 180
⇒[tex] \sf{7x = 175}[/tex]
Divide both sides of the equation by 7
⇒[tex] \sf{ \frac{7x}{7} = \frac{175}{7} }[/tex]
Calculate
⇒[tex] \sf{x = 25°}[/tex]
Finding the value of ( x + 5 )°
[tex] \sf{x + 5}[/tex]
plug the value of x
⇒[tex] \sf{25 + 5}[/tex]
Add the numbers
⇒[tex] \sf{30°}[/tex]
Finding the value of 5x
[tex] \sf{5 \times 25}[/tex]
Multiply the numbers
⇒[tex] \sf{125°}[/tex]
Hope I helped!
Best regards!!
Answer:
x° = 25°
(x + 5)° = 30°
5x° = 125°
Step-by-step explanation:
total angle inside the triangle = 180 = x + (x+5) + 5x
180 = x + x + 5 + 5x
group like terms
7x + 5 = 180
subtract 5 each sides
7x = 175
x = 175/7
x = 25°
solve for : (x + 5)°
(x + 5)° = 25 + 5
(x + 5)° = 30°
solve for 5x°
5x° = 5 * 25
5x° = 125
check
180 = x + (x+5) + 5x
180 = 25 + (25+5) + (5*25)
180 = 25 + 30 + 125
180 = 180
Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5). What are the coordinates after the two transformations: Reflection over the y-axis and rotation at 180 degrees around the origin
Answer:
R''(2,-3), S''(-2,-1) and T'(-1,-5).
Step-by-step explanation:
The given vertices of triangle are R(2, 3), S(-2, 1), and T(-1, 5).
Reflection over the y-axis:
[tex](x,y)\to (-x,y)[/tex]
Using this rule, the vertices after reflection are
[tex]R(2,3)\to R'(-2,3)[/tex]
[tex]S(-2,1)\to S'(2,1)[/tex]
[tex]T(-1,5)\to T'(1,5)[/tex]
Rotation at 180 degrees around the origin.
[tex](x,y)\to (-x,-y)[/tex]
Using this rule, the vertices after reflection are
[tex]R'(-2,3)\to R''(2,-3)[/tex]
[tex]S'(2,1)\to S''(-2,-1)[/tex]
[tex]T'(1,5)\to T''(-1,-5)[/tex]
Therefore, the coordinates of vertices after the two transformations are R''(2,-3), S''(-2,-1) and T'(-1,-5).

It studies layers of organisational behavior in the level of individual players in an organisation, work group of individual players in an organization, and the nature of interaction between organizations on the larger scale. One of the perspective of study of organizational behavior is to study people as resources.
Find the equation of the line parallel to y= -5x-3 that passes through the point ( -5, -4). If possible, write the equation in slope-intercept form.
Answer:
y = -5x - 29
Step-by-step explanation:
y-intercept form is y = mx +b,
m is slope, for parallel line slope is the same, so m= -5
y = -5x + b
To find b, we need to use the point (-5, - 4).
- 4 = -5*(-5) + b
- 4 = 25 + b
b = - 29
y = -5x - 29
Prove the following using a direct proof:
The sum of the squares of 4 consecutive integers is an even integer.
It is proven that "the sum of the squares of four consecutive integers is an even integer" is the solution part.
To prove that the sum of the squares of four consecutive integers is an even integer, we need to show that it can be expressed as twice another integer.
Let's assume the four consecutive integers are n, n+1, n+2, and n+3.
The sum of their squares can be expressed as:
[tex]n^2 + (n+1)^2 + (n+2)^2 + (n+3)^2[/tex]
Expanding the squares, we have:
[tex]n^2 + (n^2 + 2n + 1) + (n^2 + 4n + 4) + (n^2 + 6n + 9)[/tex]
Combining like terms, we simplify this expression to:
[tex]4n^2 + 12n + 14[/tex]
Now, let's consider this expression [tex]4n^2 + 12n + 14[/tex].
We can factor out 2 from each term, resulting in:
[tex]2(2n^2 + 6n + 7)[/tex]
Since [tex]2n^2 + 6n + 7[/tex] is an integer, let's denote it as k, where k is an integer.
Therefore, the expression becomes:
2k.
We have successfully expressed the sum of the squares of four consecutive integers as twice another integer (2k), which proves that it is an even integer.
Hence, the sum of the squares of four consecutive integers is an even integer.

Find the limit. Use l'Hospital's Rule if appropriate. If there is a more elementary method, consider using it. lim x→1 3x x − 1 − 3 ln(x)
Answer:
3/2Step-by-step explanation:
Given the limit of a function expressed as [tex]\lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})[/tex], we are to evaluate it. To evaluate it, we will simply substitute x = 1 into the function since the variable x tends to 1.
[tex]\lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})\\\\= (\dfrac{3(1)}{1-1} - \dfrac{3}{ln1})\\\\= \dfrac{3}{0} - \dfrac{3}{0}\\\\= \infty - \infty (ind)[/tex]
Since we got an indeterminate function, we will find the LCM of the function and solve again.
[tex]= \lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})\\\\= \lim_{x \to 1} \dfrac{3xlnx-3(x-1)}{(x-1)lnx}\\\\\\= \dfrac{3(1)ln(1)-3(1-1)}{(1-1)ln1}\\\\= \frac{3(0)-3(0)}{0(0)} \\\\= \frac{0}{0} (ind)[/tex]
Applying L'hospital rule;
[tex]\frac{x}{y} = \lim_{x \to 1} \dfrac{d/dx(3xlnx-3(x-1))}{d/dx((x-1)lnx)}\\\\= \lim_{x \to 1} \dfrac{3x(\frac{1}{x})+ 3lnx-3)}{(x-1)\frac{1}{x} +lnx}\\\\= \lim_{x \to 1} \dfrac{3 + 3lnx-3}{(x-1)\frac{1}{x} +lnx}\\\\= \frac{3ln1}{(1-1)\frac{1}{1} +ln1}\\\\= \frac{0}{0} (ind)[/tex]
Applying L'hospital rule again;
[tex]= \lim_{x \to 1} \dfrac{\frac{d}{dx} (3lnx)}{\frac{d}{dx} ((x-1)\frac{1}{x} +lnx)}\\\\= \lim_{x \to 1} \dfrac{\frac{3}{x} }{(x-1)\frac{-1}{x^2} + \frac{1}{x} +\frac{1}{x} }\\\\= \dfrac{\frac{3}{1} }{(1-1)\frac{-1}{1^2} + \frac{1}{1} +\frac{1}{1} }\\\\= \frac{3}{0(-1)+2}\\ \\= \frac{3}{2-0}\\ \\= 3/2[/tex]
Hence the limit of the function is 3/2.

Graph the equation.
y= 1/8(x-6)(x+2)
Answer:
see below
Step-by-step explanation:
See the attachment.
The graph will have x-intercepts where the factors are zero, at x=6 and x=-2. The y-intercept will be the value when x=0: (1/8)(-6)(2) = -1.5.
The axis of symmetry is halfway between the zeros, so is x = (6-2)/2 = 2.
The minimum value of the function is at x=2, so is ...
y = (1/8)(2 -6)(2 +2) = 1/8(-16) = -2
Other y-values can be found by substituting other x-values in the equation and evaluating it. Rather than go to that trouble, I prefer to use a graphing calculator.

a. 676 9
b. 7.99
c. 0.73
d. 8.457
The answer is 0.73 because in 0.975 the value of digit 7 is 7/100 ,10 times of 7/100 is 7/10 and the value of 7 in 0.73 is 7/10 ;.tenth value.
The value of each digit in a number is known as the place value. The number is 0.73. The correct option is C.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10The value of digit 7 in the number 0.975 is hundredth. Therefore, the digit 7 in the number 0.975 is equal to 7/100.
Now, if the number is 10 times as great as digit 7 in 0.975. Therefore,
7/100 x 10 = 7/10 = 0.7
Thus, the number in which digit 7 have a value that is 10 times as great as the digit 7 in the number 0.975 is the number that is at the first place after the decimal.
Hence, the number is 0.73.
