Find the quotient to -3/4divided by 5/8 show work

Mathematics

Anika [276]3 years ago

The answer to your question would be shown in steps. The decimal form is -1.2. You need to do a formula called "Keep, Change, Switch," which -3/4 is kept, division is turned into multiplication, and 5/8 is switched to make 8/5. Now we do the math, so we multiply -3 by 8 and 4 by 5, giving us from a fraction, -24/20, but you can simplify that, giving us the fraction, -1' 1/5 (I put ' as in that any number to the left of ' is a whole number, not a fraction for a numerator or denominator.

Hope this helped!

Find the roots of the equation x^3-3x^2+x+5
leonid [27]
First observe that x=-1 is a root of the equation. Use long division to divide x^3-3x^2+x+5 by x+1, we find that (x^3-3x^2+x+5)/(x+1)=(x^2-4x+5). Now we need to find the roots of x^2-4x+5.
x^2-4x+5=0, 
x^2-4x+4=-1,
(x-2)^2=i,
x-2=i or -1,
x=2+i or 2-i. 
The three roots are 2+i, 2-i, -1.

a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches. Find the angle between the diagonal of the box
ANTONII [103]

Answer:

0.7246 radians

Step-by-step explanation:

According to the Question,

Given that, a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches

  • The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:

d = √{ (12)² +(15)² }  = √(144+225) = √369inches

  • The tangent of the angle is the ratio of the height of the box to this length

 Tan∅ = 17/√369

Taking the Tan^{-1} , we have

∅ = Tan^{-1}(17/√369) ≈ 0.7246 radians

Help math plz! Giving brainlist :D
adoni [48]
No, there is not common ratio...

0.972  (common ratio is 0.3...10.8*.3*.3)

you can use the geometric mean to find this center value easily...

(18*8)^(1/2)=12
