Find the area and the circumference of a circle with diameter 7 cm.
Use the value 3.14 for it, and do not round your answers. Be sure to include the correct units in your answers.
cm
Area:
7 cm
Circumference:
Х
Answer:
area = 38.465^2 cm
circumference = 21.98 cm
Step-by-step explanation:
area =
divide the diameter by itself and multiply radius by itself and multiply by 3.14
7/2 = 3.5 | (3.5)^2 = 12.25 | (12.25) (31.4) = 38.465^2 cm
circumference =
multiply the diameter by 3.14
(7) (3.14) | 21.98

Mikayla borrowed $ 40 from her mom . The function y = - 8x + 401 represents her outstanding balance y after x weekly payments, find the zero of the function.
Answer:
[tex]\frac{401}{8}[/tex]
Step-by-step explanation:
[tex]\sf{y\:can\:also\:be\:refered\:to\:as\:f(x)}[/tex]
[tex]\sf{Zeros\: are\: also\: called\: roots.}[/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].
[tex]y = - 8x + 401\\\\0 = - 8x + 401\\[/tex]
[tex]-8x+401=0\\\\-8x+401-401=0-401\\\\-8x=-401\\\\\frac{-8x}{-8}=\frac{-401}{-8}\\\\x=\frac{401}{8}[/tex]
[tex]\sf{Therefore,\: the\: zero\: of\: this\: function\: is\: \frac{401}{8}[/tex]
[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]
Your answer is essentially correct. Either what you submitted doesn't have enough precision or you're expected to give an exact answer (-√5/8).

find the horizontal and vertical asymptotes of the graph of the function f(x) = 2x^2+1/3x-5
Answer:
HA= None VA= 5/3
Step-by-step explanation:
The HA is none because the bottom part is missing x squared so you add x squared and it will be 2/0 which means it's not possible which means HA= none. VA is 5/3 because you set the denominator to 0 so you add 5 then divide by 3 so the answer for VA is 5/3
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

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

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)

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%.
