Hi there!

7/9 is equal to 0.77777 (repeating over and over again)
This fraction cannot be simplified any lower than what it is.
But yes, the decimal number of this is 0.77778 (rounded off this answer would be 0.7778.)

Hope this helps!

Which is traveling faster, a car whose velocity vector is 201 + 25), or a car whose velocity vector is 30i, assuming that the un
ioda

Answer with explanation:

For any object having the velocity vector as

\overrightarrow{v}=v_x\widehat{i}+v_y\widehat{j}+v_z\widehat{k}

the magnitude of velocity is given by

|v|=\sqrt{v_x^2+v_y^2+v_z^2}

For car 1 the velocity vector is

\overrightarrow{v}_1=20\widehat{i}+25\widehat{j}

Therefore

|v_1|=\sqrt{20^2+25^2}\\\\\therefore v_1=32.0156units

Similarly for car 2 we have

\overrightarrow{v}_2=30\widehat{i}

Therefore

|v_2|=\sqrt{30^2}\\\\\therefore v_2=30.0units

Comparing both the values we find that car 1 has the greater speed.

Determine the equation of the inverse of y=1/4x^3-2
dedylja [7]

<u>Answer</u>


y⁻¹ = ∛(4x+8)



<u>Explanation</u>

y=(1/4)x³ - 2.

To find the inverse of this equation, you first make x the subject of the formular.

y=(1/4)x³ - 2

Multiply both sides by 4;

4y = x³ - 8

Add 8 on both sides of the equation;

4y + 8 = x³

x³ = 4y + 8

Apply the cube root on both sides to get the value of x;

x = ∛(4y+8)


The inverse of y=(1/4)x³ - 2 is;

y⁻¹ = ∛(4x+8)

Plsss help (Cuz i'm dumb:D) Calculate the surface area of the prism below, shape below
marin [14]
Surface area of the the rectangles:
8 * 5 + 8 * 4 + 8 * 3 = 96

Surface area of the two triangles:
Use bh/2 base time height over 2
(4 * 3)/2 = 6
There are 2 triangles, 2 * 6 = 12

12 + 96 = 108
