Find the value of k for which the equation 2x2 - parenthesis k - 1 parenthesis x plus 80 equals 0 will have real and equal roots?
A quadratic of the form ax² + bx + c = 0 has two equal (real) roots when the determinant of b²-4ac = 0. Thus, for: 2x² - (k - 1)x + 80 = 0 b² - 4ac = (-(k - 1))² - 4×2×80 = 0 → (k - 1)² = 640 → k - 1 = ±√640 → k = 1 ± √640 → k ≈ 26.298 or -24.298
What does 0 degrees k mean?
The "k" is Kelvin, a temperature scale like Fahrenheit or Celsius. "0" Kelvin is absolute zero. For more on Kelvin see: http:/en.wikipedia.org/wiki/Kelvin For more about absolute zero, see: http:/en.wikipedia.org/wiki/Absolute_zero
Solving quadratic equations by factoring?
(k + 1)(k - 5)= 0
How would you write the algebraic expression double k then subtract 5?
If you mean: kk-5 then it can be k^2-5 But if you mean: k+k-5 then it can be 2k-5
What s the value of k when the equation x squared plus 2kx plus 10x plus k squared plus 5 equals 0 has equal roots?
Equation: x^2 +2kx +10x +k^2 +5 = 0 Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0 Multiplying out the brackets: 4k^2 +40K +100 -4k^2 -20 = 0 Collecting like terms: 40k +80 = 0 => 40k = -80 => k = -80/40 Therefore the value of k = -2
Why you can divide 0 by 3 but not 3 by 0?
3*0 = 0 Dividing both sides by 3 gives 0 = 0/3 and therefore 0/3 is defined and is equal to 0. However, there is no number, k, such that k*0 = 3 and so division by 0 is not defined. If there were such a number k, then you could divide both sides by k to give 0 = 3/k. But there is no such k.
What is k minus k?
k - k = 0
What is K mean?
K is a symbol for Kelvin Temperature, which is a measurement of temperature based on the value 0 being the absolute zero. Also potassium has the symbol K in the Periodic Table.
What is K mean scientifically?
K is a symbol for Kelvin Temperature, which is a measurement of temperature based on the value 0 being the absolute zero. Also potassium has the symbol K in the periodic table.
How do you write a C-program for matrix multiplication?
it would have a part in it like this: for (i=0; i<n; ++i) { . for (j=0; j<l; ++j) { . . sum= 0; . . for (k=0; k<m; ++k) { . . . sum += a[i][k] * b[k][j]; . . } . . c[i][j] = sum; . } }
Factor the expression 2 k squared minus k minus 4 equals 0?
2 k^2 - k - 4 = 0 2 (k^2 - (1/2)k - 2) = 0 2 ((k - 1/4)^2 - 1/16 - 2) = 0 2 ((k - 1/4)^2 - 33/16) = 0 2 (k - 1/4 - sqrt(33)/4)(k - 1/4 + sqrt(33)/4) = 0 32 (4k - 1 - sqrt(33))(4k - 1 + sqrt(33)) = 0
What is a C program for square of sum of alternative prime numbers?
#includeint main(){int count,i,j,k,n,*a,sum=0;printf("Enter the value of 'n':");scanf("%d",&n);a=malloc(n*sizeof(int));for(i=1;i
What is 0 degrees in kelvins?
0 deg C = 273.15 K.0 deg F = 255.8 K (approx).
What is k in parenthesis K minus 0 then equals 1?
If you're talking about (K-0)=1, then the answer is most definitely 1.
What is the charge of ClO?
[K]+[Cl]+[O4]=0 [K]+(-1)+(-8)=0 [K]=+9
How do you use a pattern to find the product of a power of 10 and a decimal?
If the power of ten is k, where k is an integer thenif k < 0 then the decimal point moves k places to the left;if k = 0 then the decimal point does not move; andif k > 0 then the decimal point moves k places to the right.
What is 0 Kelvin in degrees Fahrenheit?
0 K is equal to -459.67 °F The theoretical temperature "absolute zero" is 0 K, -273.15 °C, or -459.67 °F. 0°K = -459.67°F = -273.15 °C
