{-4 1/2,-1,3/4,3.5,13,24 5/8 } Are these all integers

Mathematics
1 answer:
dlinn [17]2 years ago
8 0

Answer: No, not all of those numbers are integers.

Step-by-step explanation:

{-4\frac{1}{2}, -1, \frac{3}{4}, 3.5, 13, 24\frac{5}{8} }

Integers are whole numbers (including zero) that are positive or negative. Integers cannot have fractions or decimals.

Therefore, only -1 and 13 are integers, and {-4\frac{1}{2}, \frac{3}{4}, 3.5, 24\frac{5}{8} } are not integers.

How many complex zeros does the polynomial function have? <br><br> F(x)=2x^4 +5x^3 - x^2 +6x-1
klio [65]

Answer:

Two complex roots.

Step-by-step explanation:

F(x)=2x^4 +5x^3 - x^2 +6x-1

is a polynomial in x of degree 4.

Hence F(x) has 4 roots.  There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.

Use remainder theorem to find the roots of the polynomial.

F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0

There is a change of sign in F from 0 to 1

Thus there is a real root between 0 and 1.

Similarly by trial and error let us find other real root.

F(-3) = -1 and F(-4) = 94

SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.

Other two roots are complex roots since no other place F changes its sign

You can get the max points i can give for this :)
andriy [413]

Answer:

{a}^{2}  +  {b}^{2}  =  {c}^{2} \\  {a}^{2}   +  {9}^{2}  =  {17}^{2}  \\  {a}^{2} =  289 - 81 \\  {a}^{2}  = 208 \\ a = 14.42cm

Answer:

Right triangles:

5) 0.75, 1, 1.25

6) 18, 80,82

Not right triangles:

1) 5,5,√50

2) 6.5, 3.2, 7.8

3) √2, √3, 4

4) 12, 13, 20

Step-by-step explanation:

Right triangles: (for right triangles the Pythagorean theorem is true)

6) 18² + 80²  = 82²

6724=6724

5) 0.75² + 1² = 1.25²

1.5625 =1.5625

Not right triangles:

1) 5² + 5² ≠(√50)²

1250≠ 50

2) 6.5² + 3.2² ≠ 7.8²

52.49≠60.84

3) (√2)² +(√3)² ≠ 4²

5≠ 16

4) 12² + 13² ≠ 20²

313 ≠ 400
