Radius of a sphere that has a surface area 12.56in2 use 3.14

enot [183]

$\bf \textit{surface area of a sphere}\\\\
A=4\pi r^2\qquad 
\begin{cases}
r=radius\\
-----\\
A=12.56
\end{cases}\implies 12.56=4\pi r^2
\\\\\\
\cfrac{12.56}{4\pi }=r^2\implies \sqrt{\cfrac{12.56}{4\pi }}=r$

4sinθ – 1 = - 3 for 0<θ< 360

EastWind [94]

Answer:

$\theta = 210^\circ$ or $\theta = 330^\circ$

Step-by-step explanation:

$4 \sin \theta - 1 = -3$

$4 \sin \theta = -2$

$\sin \theta = \dfrac{-2}{4}$

$\sin \theta = -0.5$

For sin θ = 0.5, the reference angle is θ = 30 deg.

$\sin 30^\circ = 0.5$

$\theta = 210^\circ$ or $\theta = 330^\circ$

How is the pythogorean theorem used to determine the distance formula

Fiesta28 [93]

Answer:

The distance formula uses the coordinates of points and the Pythagorean Theorem to calculate the distance between points. If A and B form the hypotenuse of a right triangle, then the length of AB can be found using this formula, leg2 + leg2 = hypotenuse2 (or you can use A squared + B squared = C squared)

Am not a real genius but I hope that answers your question! ^w^

If R= {(1,2), (3,4), (5,6), (8,9)} find the domain and range of R a. Find value of X and Y.

podryga [215]

<h2>The Domain and Range of a Set of Ordered Pairs</h2><h3>Answer:</h3>

Domain: $x \in \{ 1, 3, 5, 8 \}$

Range: $y \in \{ 2, 4, 6, 9 \}$

<h3>Step-by-step explanation:</h3>

We are given the set of ordered pairs: $R$ . The Domain is just the set containing all the $x$ values of each ordered pair of $R$ . Recall that in the ordered pair $(a,b)$ , $a$ is the $x$ value. In set $R$ , we can see that the $x$ values are $\{ 1, 3, 5, 8 \}$ .

For the Range, it is just the set containing all the $y$ values of each ordered pair of $R$ . Recall that in the ordered pair $(a,b)$ , $b$ is the $y$ value. In set $R$ , we can see that the $y$ values are $\{ 2, 4, 6, 9 \}$ .
