(4x^5 + 3x^2 – x^4) +(6x^2 - 2x^5)

Mathematics
2 answers:
Monica [59]3 years ago
5 0

Answer:

The simplified equation is as follows 2x^5 -x^4 + 9x^2

Step-by-step explanation:

Remove the parentheses around each equation and pair like exponents together

4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2

Then combine the like terms

2x^5 - x^4 + 9x^2

It is in that order due to the proper form being to go from the highest to lowest exponents in an answer

7. The points P(2, -3), Q(3, -2) and R(8, z) are
Hatshy [7]

Answer:

z = 3

Step-by-step explanation:

Since the points are collinear then the slopes between the points are equal.

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = P (2, - 3) and (x₂, y₂ ) = Q (3, - 2)

m = \frac{-2+3}{3-2} = 1

Repeat with

(x₁, y₁ ) = Q (3, - 2) and (x₂, y₂ ) = R (8, z )

m = \frac{z+2}{8-3} = \frac{z+2}{5} , then

\frac{z+2}{5} = 1 ( multiply both sides by 5 )

z + 2 = 5 ( subtract 2 from both sides )

z = 3

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = 3x2 − 2x + 1, [0, 2] Yes, it do
expeople1 [14]

Answer:

Yes , function is continuous in [0,2] and is differentiable (0,2) since polynomial function are continuous and differentiable

Step-by-step explanation:

We are given the Function

f(x) =3x^2 -2x +1

The two basic hypothesis of the mean valued theorem are

  • The function should be continuous in [0,2]
  • The function should be differentiable in (1,2)

upon checking the condition stated above on the given function

f(x) is continuous in the interval [0,2] as the functions is quadratic and we  can conclude that from its graph

also the f(x) is differentiable in (0,2)

f'(x) = 6x - 2

Now the function satisfies both the conditions

so applying MVT

6x-2 = f(2) - f(0) / 2-0

6x-2 = 9 - 1 /2

6x-2 = 4

6x=6

x=1

so this is the tangent line for this given function.

I have a box of chocolates with white, milk and dark chocolate in. The ratio of white to not white is 3:4. The ratio of not dark
Scrat [10]

white : milk : dark

w : m : d

The ratio of white to not white is 3:4

w : (m+d) = 3:4

The ratio of not dark to dark is 17:4.

(w+m) : d = 17:4

---------

We treat the colons as fraction bars and cross multiply.

4w = 3(m+d) = 3m + 3d

4w + 4m = 17 d

Subtracting,

4m = 17d - (3m+3d) = 14d - 3m

7m = 14 d

m/d = 14/7

m:d = 2:1

Since w:(m+d)=3:4 let's make m+d a multiple of 4.

m:d = 8:4

w : (m+d) = 3:4 = 9:12

w:m:d = 9:8:4

Answer: 9:8:4

Check:

white to non white 9 to 8+4=12 = 3:4, good

non dark to dark (9+8):4=17:4, good
