Answer:

The domain is a set/group of x-values. The range is a set/group of y-values. The first option is not true because there are x-values which are greater than 0 (right side of graph). The second option is not true because the set of y-value stops before it hits the y=0. The third option is not true because there are no y-values which are less than 0 (bottom of graph). The fourth option is correct because the x-values stretch from -infinity on the left side of the graph to positive infinity of the right side of the graph.

Solve for c.<br> -c/2+43 = 50

noname [10]

$\huge\text{Hey there!}$

$\mathsf{-\dfrac{c}{2}+43=50}$

$\large\text{SUBTRACT 43 to BOTH SIDES}$

$\mathsf{-\dfrac{c}{2}+43-43=50-43}$

$\large\textsf{CANCEL out: 43 - 43 because that gives you 0}$

$\large\textsf{KEEP: 50 - 43 because it helps solve for the c-value}$

$\mathsf{50 - 43 = \bf 7}$

$\large\text{NEW EQUATION: }\mathsf{-\dfrac{c}{2}=7}$

$\large\textsf{MULTIPLY }\mathsf{\dfrac{2}{-1}}\large\textsf{ to BOTH SIDES}$

$\mathsf{\dfrac{2}{-1}\times-\dfrac{c}{2}= \dfrac{2}{-1}\times7}$

$\large\textsf{CANCEL out: your RIGHT SIDE of the equation because that gives}\\\large\textsf{you 1}$

$\large\textsf{KEEP: }\mathsf{\dfrac{2}{-1}\times7}\large\textsf{ because that helps solve for the c-value}$

$\uparrow\large\text{SIMPLIFY THE EQUATION ABOVE \& YOU HAVE YOUR}\\\large\text{C-VALUE}\uparrow$

$\boxed{\boxed{\large\text{ANSWER: \huge\bf c = -14}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

I need help ASAP plzzzzzzzzzzzzz

n200080 [17]

Answer:

3/4

Step-by-step explanation:

Let's say that r is the radius of the large circle or the diameter of the small circle.

Area of the big circle is $\pi r^{2}$ .

Area of the small circle is $\pi \frac{r}{2} ^{2} = \pi \frac{r^{2}}{4}$ .

The ratio of these 2 circles is 1/4 (calculation in the comments).

So the shaded part represent 1 - 1/4 = 3/4.

Felipe Rivera's savings account has a balance of 2163 After 3yrs what will the amount of interest be at 4% compounded quarterly

kiruha [24]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$2163\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &3 \end{cases} \\\\\\ A=2163\left(1+\frac{0.04}{4}\right)^{4\cdot 3}\implies A=2163(1.01)^{12}\implies A\approx 2437.3225$
