Y - (-1) = ⁻⁵/₇[x - (-4)]
y + 1 = ⁻⁵/₇(x + 4)
y + 1 = ⁻⁵/₇(x) - ⁵/₇(4)
y + 1 = ⁻⁵/₇x - 2⁶/₇
- 1 - 1
y = ⁻⁵/₇x - 3⁶/₇

Please at least help me with one of them cause I have no idea

Answer:

Solving $v = \frac{4}{3}\pi r^3$ for r gives us: $r=\sqrt[3]{\frac{3v}{4\pi}}$

Solving $a_{ave} = \frac{v_2-v_1}{t_2-t_1}$ for v2 gives us: $v_2 = (t_2-t_1)a_{ave}+v_1$

Step-by-step explanation:

Solving an equation for a variable or constant means that we have to isolate the value on one side of the equation or write the whole equation in terms of that variable or constant.

Now,

Solving $v = \frac{4}{3}\pi r^3$ for r

$v = \frac{4}{3}\pi r^3$

Multiplying whole equation by 3/4

$\frac{3}{4}.v = \frac{3}{4}.\frac{4}{3} \pi r^3$

$\frac{3}{4}v = \pi r^3$

Dividing by Pi on both sides

$\frac{3v}{4\pi} = \frac{\pi r^3}{\pi}\\\frac{3v}{4\pi} = r^3$

Taking cube root on both sides

$\sqrt[3]{r^3} = \sqrt[3]{\frac{3v}{4\pi}} \\r = \sqrt[3]{\frac{3v}{4\pi}}$

Now

Solving $a_{ave} = \frac{v_2-v_1}{t_2-t_1}$ for v2

Multiplying both sides by (t2-t1)

$(t_2-t_1)a_{ave} = \frac{v_2-v_1}{t_2-t_1}(t_2-t_1)\\(t_2-t_1)a_{ave} = v_2-v_1$

Adding v1 on both sides

$(t_2-t_1)a_{ave}+v_1 = v_2-v_1+v_1\\(t_2-t_1)a_{ave}+v_1 = v_2$

Hence,

Solving $v = \frac{4}{3}\pi r^3$ for r gives us: $r=\sqrt[3]{\frac{3v}{4\pi}}$

Solving $a_{ave} = \frac{v_2-v_1}{t_2-t_1}$ for v2 gives us: $v_2 = (t_2-t_1)a_{ave}+v_1$

Find the unknown side length, x. Write your answer in simple

Bumek [7]

Answer:

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 32² = 48²

x² + 1024 = 2304 ( subtract 1024 from both sides )

x² = 1280 ( take the square root of both sides )

x = $\sqrt{1280}$

= $\sqrt{256(5)}$

= $\sqrt{256}$ × $\sqrt{5}$

= 16 $\sqrt{5}$ → C

Which expression is equivalent to<br> %?

olganol [36]

Answer:

$x^{\frac{2}{3} }$

Step-by-step explanation:

⇒ $x^({\frac{4+2}{3}) } ^{\frac{1}{3} }$

⇒ $(x^{\frac{6}{3} })$

⇒ $(x^{2} )\frac{1}{3}$

⇒ $x^{\frac{2}{3} }$
