The speed of an object can be found by taking the distance it travels and dividing it by the time it takes to travel that distance. An object travels 100 feet in 2.5 seconds let the speed, S, be measured in feet per second. True or false: the equation
Answer:
True the speed S in in Feet/secondStep-by-step explanation:
In this problem we are required to solve for the speed of an object.
given that the expression to solve for the speed is expressed as
speed= distance/time
given data
distance=100 feet
time=2.5 seconds
substituting our given data into the expression we can solve for speed as
speed (S)=100/2.5
S= 40feet/seconds
upon substituting our data the speed S was found to be 40feet/s
True the speed S in in Feet/second

Write an equation for the line that passes through the points (3,5) and (-2, 1).
All work must be shown for full credit. Be sure to include slope calculation.
Answer:
[tex]\displaystyle y=\frac{4}{5}x+\frac{13}{5}[/tex]
Step-by-step explanation:
The equation of the line in slope-intercept form is:
y=mx+b
Where m the slope of the line and b the y-intercept.
When two points are given, it's convenient to calculate the slope first.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (3,5) and (-2,1):
[tex]\displaystyle m=\frac{1-5}{-2-3}=\frac{4}{5}[/tex]
The equation is now:
[tex]\displaystyle y=\frac{4}{5}x+b[/tex]
To calculate b, we use any of the given points and solve for b. Use (3,5):
[tex]\displaystyle 5=\frac{4}{5}3+b[/tex]
Operate:
[tex]\displaystyle 5=\frac{12}{5}+b[/tex]
Solve:
[tex]\displaystyle b=5-\frac{12}{5}=\frac{13}{5}[/tex]
The required equation of the line is:
[tex]\boxed{\displaystyle y=\frac{4}{5}x+\frac{13}{5}}[/tex]
A table of equivalent ratios is shown. One value is missing from the table.
Which value is missing from the table?

What is the minimum value of F(x)= 10x^{2} -6x-3
3/10 or -39/10
Answer: 3/10
Step-by-step explanation:
Take the derivative of [tex]10x^2-6x-3[/tex] to get [tex]20x-6[/tex]. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.
Now do:
[tex]20x-6=0\\20x=6\\x=\frac{6}{20} = \frac{3}{10}[/tex]
There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.
Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value

Jackie plays football for the New England Patriots. During the second quarter, Jackie carried the ball 2 times. He gained four yards during the first carry and lost seven yards during the second. HOw many total yards did he gain during the second quarter?
Answer:
Actually he lost 3 yards.
It means he gained -3 yards.
Step-by-step explanation:
During second quarter, Jackie carried the ball 2 times. He gained 4 yards during first carry.
He lost 7 on second carry.
He gained = 4-7 =-3 yards
What is the value of x? What is the value of y?
Answer:
x = 45/2y = 10Step-by-step explanation:
Both angles that have the "x" variable are the same and both angles that the "y" are the same since they are congruent meaning they are the same angle measure.
Solve for x.
6x - 5 = 8x - 50
~Add 5 to both sides
6x = 8x - 45
~Subtract 8 to both sides
-2x = -45
~Divide -2 to both sides
x = 45/2
Solve for y.
2y + 30 = 3y + 20
~Subtract 30 to both sides
2y = 3y - 10
~Subtract 3y to both sides
-y = -10
~Divide -1 to both sides
y = 10
Best of Luck!

which elephants weight 2.85 tons when rounded to the nearest hundredth? Is it
tiny: 2.805 tons

fanny: 2.849 tons
Those are the 4 chooses and I am confused on it
The elephant that weigh 2.85 tons after rounding up is [tex](fanny: 2.849 tons)[/tex]
We are required to round to nearest hundredth so that the elephant could have a weight of 2.85 tons.First option [tex]:2.805 tons[/tex]if we round this up starting from right hand side, if we round the 5 up then it will become 1 then we have [tex]2.81 tons[/tex]Second option: 2.861 tonsIf we round up, then since 1 is not up to 5 so it becomes zero, then we have[tex]2.86 tons[/tex]Third option: 2.842 tons If we round up, then since 2 is not up to 5 so it becomes zero, then we have[tex]2.84 tons[/tex]Fourth option:2.849 tonsif we round 9 up, it will become 1, then we will add it to 4, then we have [tex]2.45 ton.[/tex]Therefore, Fourth option is correct.
