If u(x)= x^5-x^4+x^2 and v(x)= -x^2, which expression is equivalent to (u/v)(x)? Ox^3-x^2 O -x^3+x^2 O-x^3+x^2-1 Ox^3-x^2+1​
djverab [1.8K]

Answer:

  • C. -x^3 + x^2 - 1

Step-by-step explanation:

<u>Given</u>

  • u(x) = x^5 - x^4 + x^2 and v(x) = -x^2

<u>(u/v)(x) = </u>

  • (x^5 - x^4 + x^2) /(- x^2) =
  • - (x^3 - x^2 + 1) =
  • -x^3 + x^2 - 1

Correct option is C

I’m stuck, need help!!
grigory [225]

Answer:

Step-by-step explanation:

A + B + C = 180

x + x - 24 + 68 = 180

2x - 24 + 68 = 180

2x + 44 = 180

2x = 180 - 44

2x = 136

x = 68

A = 68

B = 44

C = 68

Choose the regular polygon that has interior angles with a sum of 900 degrees.
svlad2 [7]
A triangle has 3 sides, the total interior angels sum to 180 degrees.
A square has 4 sides, the total interior angels sum to 360 degrees.
A pentagon has 5 sides, the total interior angels sum to 540 degrees.
Do you see a trend?
Answer:
The (s) sum of interior angles equals the (n) number of sides, minus 2, times 180.
This is written as
s = (n - 2) * 180

If we put in 900 for s, we get
900 = (n - 2) * 180

5  = n - 2
n = 7
A polygon with 7 sides is called a Heptagon.

What is the volume of a rectangular prism with the dimensions: base 3 1 2 cm, height 1 1 2 cm, and length 5 1 2 cm?
aleksandrvk [35]

Answer:

The volume of a rectangular prism is 28\frac{7}{8}\ cm^{3}

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

V=BHL

Convert the given dimensions to an improper fractions

B=3\frac{1}{2}\ cm=\frac{3*2+1}{2}=\frac{7}{2}\ cm

H=1\frac{1}{2}\ cm=\frac{1*2+1}{2}=\frac{3}{2}\ cm

L=5\frac{1}{2}\ cm=\frac{5*2+1}{2}=\frac{11}{2}\ cm

substitute in the formula

V=(\frac{7}{2})(\frac{3}{2})(\frac{11}{2})=\frac{231}{8}\ cm^{3}

Convert to mixed number

\frac{231}{8}=\frac{224}{8}+\frac{7}{8}=28\frac{7}{8}\ cm^{3}
