SVEN [57.7K]

<u><em>Answer:</em></u>

Radius of the ball is approximately 6.5 cm to the nearest tenth

<u><em>Explanation:</em></u>

The ball has the shape of a sphere

<u>Surface area of a sphere can be calculated using the following rule:</u>

Surface area of sphere = 4πr² square units

<u>In the given problem, we have:</u>

Surface area of the ball = 531 cm²

<u>Substitute with the area in the above equation and solve for the radius as follows:</u>

531 = 4\pi r^2\\ r^2=\frac{531}{4\pi } = 42.255 \\ \\ r=\sqrt{42.255}=6.5004 cm which is approximately 6.5 cm to the nearest tenth

Hope this helps :)

X&lt;= -2 on a number line
ruslelena [56]

Answer:

x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.

Step-by-step explanation:

Given the inequality expression

x ≤ -2

The inequality symbol ' ≤ ' means 'less than or equal to'.

Thus,

x ≤ -2 means x is less than or equal to -2.

In other words,

x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.

Find the functions y-intercept algebraically
grigory [225]
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve y. Hope this helped! :)
