Find the circumference of the circle and show work

expeople1 [14]

Answer:

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Circumference of a circle is given by

$C = 2\pi \: r$

Given - Diameter of circle = 10 yards

$radius = \frac{diameter}{2} = \frac{10}{2} \\ \\ \implies \: 5 \: yards$

now ,

substituting the value of r in the formula of circumference ~

$C = 2 \times \frac{22}{7} \times 5 \\ \\ \implies \: C = \frac{220}{7} \\ \\ \implies \: C = 31.43 \: yards \: (approx.)$

hope helpful :D

The graph of f(x), shown below has the same shape as the graph has the same shape as the graph of g(x)=x^4-X^2 which contains th

Alenkasestr [34]

First of all it is always a good idea to graph a question like this one. Here are the three graphs

y = x^4 - x^2 Color: Red This is the base graph
y = x^4 - x^2 - 4 Color Blue This has - 4 added to it.
y = x^4 - x^2 + 4 Color Green This has 4 added to the base graph

Which one is correct? The red and blue one are not. The graph you want is plotted upward from the base graph. The base graph (red nothing added to it) is not right because it has points on the x axis. The graph you want does not.

The same is true of the blue graph. It cuts the x axis. That only leaves the green one.

Answer: C

Howard’s uncle gave him $885 for his tenth birthday. The money was invested in a savings account with interest compounded at 12%

Stella [2.4K]

Principal Amount = P = $885
Amount Accumulated = A = $3500
Interest rate = r = 12% = 0.12
Compounding period in a year = n = 2
Time in years = t = ?

The formula for compounding is:

$A=P(1+ \frac{r}{n})^{t*n}$

Using the values, we get:

$3500=885(1+ \frac{0.12}{2})^{2*t} \\ \\ 
 \frac{3500}{885} =(1.06)^{2t} \\ \\ 
log(\frac{3500}{885})=log((1.06)^{2t}) \\ \\ 
log(\frac{3500}{885})=2tlog(1.06) \\ \\ 
t= \frac{log(\frac{3500}{885})}{2log(1.06)} \\ \\ \\ 
t=11.80$

This means, it will take him 11.8 or approximately 12 years
