Answer:
[tex]2[/tex] would be the slope of a line that goes between [tex](-4,\, -8)[/tex] and [tex](3,\, 6)[/tex].
Step-by-step explanation:
Given a line that goes through two points, [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] ([tex]x_{0} \ne x_{1}[/tex],) the slope of this line would be equal to the "rise over run" between these two points.
"Rise" refers to the change in the [tex]y[/tex]-coordinate between the two points, [tex](y_{1} - y_{0})[/tex]. Similarly, "run" refers to the change in the [tex]x[/tex]-coordinate, [tex](x_{1} - x_{0})[/tex].
[tex]\begin{aligned} \text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}}\end{aligned}[/tex].
For [tex](-4,\, -8)[/tex], the [tex]x[/tex]-coordinate is [tex]x_{0} = (-4)[/tex] and the [tex]y[/tex]-coordinate is [tex]y_{0} = -8[/tex].
For [tex](3,\, 6)[/tex], the [tex]x[/tex]-coordinate is [tex]x_{1} = 3[/tex] and the [tex]y[/tex]-coordinate is [tex]y_{1} = 6[/tex].
The "rise" between these two points would be [tex]y_{1} - y_{0} = 6 - (-8) = 14[/tex].
The "run" between these two points would be [tex]x_{1} - x_{0} = 3 - (-4) = 7[/tex].
Thus, the slope of a line that goes through the two points would be:
[tex]\begin{aligned} \text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}} \\ &= \frac{14}{7} \\ &= 2\end{aligned}[/tex].

Weight of cats, in pounds: 9, 11, 11, 12, 14, 14, 15, 15, 16, 17, 18, 18, 20, 22
Lowest value: 9
Highest value: 22
Spread: 9 = 1, 11 = 2, 12 = 1, 14 = 2, 15 = 2, 16 = 1, 17 = 1, 18 = 2, 20 = 1, 22 = 1
Center value: (15 + 15)/2 = 30/2 = 15
There are about 1.61 kilometers in 1 mile. Let x represent the distance measured in kilometers and y represent the same distance measured in miles. Write two equations that relate a distance measured in kilometers and the same distance measured in miles.
kilometers = miles * 1.61
Miles = kilometers / 1.61
Now replace miles with y and kilometers with x
x = 1.61y
y = x/1.61
A wedding ring costs £13000. Work out the price after a 11% price increase
Answer:
Step-by-step explanation:
Increased price = 11% of £ 13000
= 0.11 * 13000
= 1430
Price after increase = 13000 + 1430 = £ 14,430
[tex] \frac{dh}{dt} = - \sqrt{5h} [/tex]
Determine
[tex] \frac{ {d}^{2}h }{d {t}^{2} } [/tex]
at h=16
I have attempted this and keep on getting about -0.28, but that is not an option.
If
[tex]\dfrac{dh}{dt} = -\sqrt{5h} = -\sqrt{5} \cdot h^{\frac12}[/tex]
then its derivative, using the power rule, is
[tex]\dfrac{d^2h}{dt^2} = -\sqrt{5} \cdot \dfrac12 h^{1-\frac12} = -\dfrac{\sqrt5}2 h^{-\frac12} = -\dfrac{\sqrt5}{2\sqrt h} = -\sqrt{\dfrac{5}{4h}}[/tex]
At h = 16, the second derivative has a value of
[tex]-\sqrt{\dfrac{5}{4\cdot16}} = -\sqrt{\dfrac{5}{64}} = -\dfrac{\sqrt5}{8} \approx -0.279508[/tex]

Nigerian Savings Bank pays interest at 9½% per annum compounded yearly. What is the amount if a person saves:
a N 5000 for 2 years
b N10 000 for 4 years
c N28 000 for 3 years?
Answer:
a) N5995.13
b) N14376.61
c) N36762.11
Step-by-step explanation:
For repetitive calculations, I like to use a spreadsheet or graphing calculator. __
The formula for the amount is ...
A = P(1 +r)^t . . . . . . where principal P is invested for t years at rate r compounded annually
a)The principal being invested is P = 5000. The interest rate is r = 9.5% = 0.095, and the time is t = 2 years. Putting these values into the formula gives ...
A = 5000(1 +0.095)^2
= 5000(1.199025) = 5995.125
This rounds to an account balance after 2 years of N5995.13.
The calculations for the other amounts and time periods are done the same way, but for different values of P and t. You can do these calculations by hand, but it is generally much easier to use a calculator, spreadsheet, or other tool.
The attachment shows use of a tool that lets a function be defined that takes P and t as arguments. It is shown as being evaluated for the different values of P and t in this problem.
b)A = N10,000(1 +0.095)^4 = N10,000(1.43766095) = N14376.6095
This rounds to an account balance after 4 years of N14376.61.
c)A = N28000(1.095)^3 ≈ N36762.11

Which rational number also belongs to the set of whole numbers?
Answer:
Answer: A) 15
A natural number is basically a counting number {1, 2, 3, 4, 5, ...} so any positive whole number. That is why 15 is the answer. Choices B and D are fractional values, so we can rule them out. We can rule out choice C because this value is negative.

At Kenner Country Club, 45% of the members swim. If 3 people are selected at random, what is the probability that all three will say they swim at the club?
Step-by-step explanation:
so, we pick the first one. the probability this person swims is 0.45.
if yes, then we pick the second one. this one has also a probability of swimming of 0.45.
combined with the probability of the first one being a swimmer this is now 0.45×0.45.
the same with the third pick.
and we have the probability that all 3 swim of
0.45×0.45×0.45 = 0.45³ = 0.091125
that is rounded about 0.09 or 9%.
How do you graph y = -x/5 +4
Answer:
So starting from (0,4) you will go down 1 space and move 5 spaces to the left and you will end up at (5,3)
Step-by-step explanation:
You will start with the y-intercept which is (0,4)
Because [tex]\frac{-x}{5} =\frac{-1}{5}[/tex]
[tex]\frac{-1}{5}[/tex] = slope which is rise/run
So starting from (0,4) you will go down 1 space and move 5 spaces to the left and you will end up at (5,3)
You will repeat this step for every new point you come across

Step-by-step explanation:
[tex]\sf{y\:can\:also\:be\:refered\:to\:as\:f(x)}[/tex]

The roots (zeros) are the [tex]x[/tex] values where the graph intersects the [tex]x[/tex]-axis. To find the roots (zeros), replace [tex]y[/tex] with 0 and solve for [tex]x[/tex].
