C) A manufacturer is making 100 times as many bows as Tess to sell in stores nationwide.
Luda [366]

1. Tess is making 12 bows.

2. 100 time as 12 bows = 100 × 12 = 1200 bows

3. In exponent form ; 12 × 10²

Given :  Number of bows Tess makes = 100 times as the of x

Let the number of bows Tess makes be x

Thus the number of bows Tess is making is 12.

100 times as many means the number which we have calculated should be multiplied by 100.

thus the number as w2e have found out is 12

so multiplied by 100 will give us 1200

Exponential form means that the given number should be expressed in the form of 10.

As the number which is given to us is 1200n

thus in exponential form we can write it as 12 multiplied by 10 raise to the power as the number of zeros of present.

Here then number of number of zeros is 2

thus 10 raised to the power 2.

Find the discriminant of the equation. x2 + 3x - 4 = 0
ivann1987 [24]

Please use " ^ " to indicate exponentiation: x^2 + 3x - 4 = 0

Here, a = 1, b = 3 and c = -4.

The formula for the discriminant is b^2 - 4(a)(c).

Substituting the given values of a, b and c, we get:

(3)^2 - 4(1)(-4)

Evaluating this, we get 9 + 16 = 25.

The discriminant is 25.

-3 plus or minus √25

Taking this further, x = ------------------------------------

2

-3 plus or minus 5

or: x = -------------------------------- => {-4, 1} (solutions)

Help pleaseeeeeeeeee
sergij07 [2.7K]

9514 1404 393

Answer:

  47 -6√10

Step-by-step explanation:

As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.

  (a -b)² = a² - 2ab + b²

  (√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²

  = 2 - 6√10 + 3²(5)

  = 47 -6√10

__

<em>Check</em>

  √2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals

  (√2-3√5)² ≈ 28.02633

  47 -6√10 ≈ 28.02633
