How do you solve k equals log4 91.8?
k=log4 91.8 4^k=91.8 -- b/c of log rules-- log 4^k=log 91.8 -- b/c of log rules-- k*log 4=log91.8 --> divide by log 4 k=log 91.8/log 4 k= 3.260
If y varies inversely as the square of x and y equals 4 when x equals 3 find y when x is 2?
y varies as 1/x^(2) y = k X 1/^(2) y = k/x^(2) k = y x^(2) When y = 4 & x = 3 Then k = 4(3^(2)) k = 4(9) k = 36 (The constant of proportionality Hence the general equation is y = 36/x^(2) When x = 2 y = 36/2^(2) y = 36 /4 y = 9 The answer!!!!!
If y varies inversely as x and y equals 12 when x equals 6 what is k the variation constant?
If y and x are related inversely, then the equation for y can be said to be:y = k/xTo find the constant k, substitute 12 for y and 6 for x (a pair of values that are known to satisfy the equation).y = k/x12 = k/612 X 6 = k72 = kThe value of the variation constant k is 72.
What is the value of k in the equation 8-4k equals 40?
8-4k = 40 (4k-8) - 8 = 40-8 4k = 32 4k/4 = 32/4 k =8
If x varies jointly as y and the square as z and x equals 40 when y equals 20 and z equals 2 find x when y equals 30 and z equals 3?
As x ∝ yz2 then x = kyz2 where k is a constant. Substituting the given figures, 40 = k*20*22 = 80k Then k = ½ and the formula is, x = ½yz2 So, x = ½ * 30 *32 = 135
What is k times 4 equals 48?
k * 4 = 48 k = 48/4 k = 12 so 12 * 4 = 48
12-4 plus k equals 85?
12 - 4 + k = 85 8 + k = 85 k = 77
If k over 3 plus k over 4 equals 1 what is k?
K/3 + k/4 = 1 LCD=12 *divide lcd by denominator* K(4) + K(3) = 12(1) 4k + 3k = 12 7k = 12 k=12/7
Negative 6 over 5 K equals 12?
The answer to negative 6 over 5K equals 12 is k equals -10.
Why must k be less than twelve for 6 x k equals 12?
k = 2 and 2 < 12
How do you write it in numbers k is a function of n and 7 times n equals k?
k = f(n) = 7n
What is k in the problem 25k plus 12 equals negative 13?
k = -1
What is the answer to 4k-3 equals 3k plus 4?
Take 3k from both sides to get k-3 equals 4, so k is 7
If A is inversely proportional to the cube of B and A equals 28.5 when B equals negative 4 write A as a power function of B?
You have:A = K / B^3The given data gives value for K :K = ( A ) ( B )^3K = ( 28.5 ) ( - 4 )^3 = - 1824A = ( - 1824 ) / B^3Answer : A = ( - 1824 ) / ( B )^3 = ( -1824 ) ( B )^( -3 )
30.92 k and omega and omega equals?
12
K-32 equals 16-2 plus 4 what is k?
50
What is negative -k plus negative -k if k equals 2?
neg(-k) + neg(-k) = k + k = 2k = 4
