Any three points define a plane so a 3 legged tripod will always be stable. that's also the reason milk stools have only 3 legs.

(30 POINTS AND BRAINLIEST) Show all work to solve 3x^2 + 5x − 2 = 0.
Dahasolnce [82]

Answer:

The answer to your question is:    (x + 2)(3x - 1) = 0

x1 = -2

x2 = 1/3

Step-by-step explanation:

                                           3x² + 5x − 2 = 0

Multiply 3 x -2 = -6

Find two numbers that added = +5 and multiply -6

These numbers are +6  and -1

Then:

                                           3x² + 6x -1x − 2 = 0

Factorize                           3x (x + 2) - 1(x + 2) = 0

Factorize again                (x + 2)(3x - 1) = 0

Finally

                         x + 2 = 0               3x - 1 = 0

                         x = -2                     x = 1/3

Can someone explain how the answer to #14 is 7/8 in;0.875 in.
Tamiku [17]

Of the 16 small intervals indicated from 0 to 1 inch, the ant spans 14 of them, so

\dfrac{14}{16} = \dfrac{7}{8} \textrm{ inches} = 0.875 \textrm{ in}

How is 7/8 equal to 0.875?

Since 125(8)=1000 and 125(7)=875 we know

\dfrac{7}{8} = \dfrac{7 \cdot 125}{8 \cdot 125} = \dfrac{875}{1000} = 0.875

How many solutions does this quadratic equation have?<br> 6p^2-7p+5=0
KatRina [158]

Answer:

It has no real solution.

Step-by-step explanation:

6p^2 − 7p + 5 = 0

For this equation: a = 6, b = -7, c = 5

6p^2+ −7p + 5 = 0

Step 1: Use quadratic formula with a=6, b=-7, c=5.

p = -b ± √b^2 - 4ac/2a

p = -(-7) ± √(-7)^2 - 4(6)(5)/2(6)

p = 7 ± √-71/12

What is the algorithm for the inverse of f (x)?<br>​
Juli2301 [7.4K]

Answer:

What is an inverse?

Recall that a number multiplied by its inverse equals 1. From basic arithmetic we know that:

The inverse of a number A is 1/A since A * 1/A = 1 (e.g. the inverse of 5 is 1/5)

All real numbers other than 0 have an inverse

Multiplying a number by the inverse of A is equivalent to dividing by A (e.g. 10/5 is the same as 10* 1/5)

What is a modular inverse?

In modular arithmetic we do not have a division operation. However, we do have modular inverses.

The modular inverse of A (mod C) is A^-1

(A * A^-1) ≡ 1 (mod C) or equivalently (A * A^-1) mod C = 1

Only the numbers coprime to C (numbers that share no prime factors with C) have a modular inverse (mod C)

Step-by-step explanation:
