Answer:

We see that it is always possible to write both M and N as the products of the same prime factors, albeit with different exponents. Some of the exponents will need to be zero.

Now, both GCD(M, N) and LCM(M, N) are products of the same prime factors where the exponents in G are the least of the corresponding two, whilst in L they are the largest:

GCD(M, N) = p min(a, α) q min(b, β)· ... · r min(c, γ),

LCM(M, N) = p max(a, α) q max(b, β)· ... · r max(c, γ).

Now, (2) thus insures that (1) holds. To continue the example:

GCD(12, 10) = 213050 = 2,

LCM(12, 10) = 223151 = 60.

Naturally, 12×10 = 2×60.

harkovskaia [24]

Answer:

b. More than half of all people prefer texting.

Step-by-step explanation:

According to the survey 56% of the respondents prefer texting over making call. This means the value of sample proportion p is:

Sample proportion = p = 56% = 0.56

The margin of error with 95% confidence interval is 3 percent points i.e.

Margin of error = M.E = 0.03

The true value of the population proportion can be expressed as the following confidence interval:

From p - M.E to p + M.E

Lower Limit = p - M.E = 0.56 - 0.03 = 0.53 = 53%

Upper Limit = p + M.E = 0.56 + 0.03 = 0.59 = 59%

From here we can see that the lower and upper limit of confidence interval are above 50%. Based on these calculations the following claim can be supported:

b. More than half of all people prefer texting.

What is the volume of the composite figure shown? (Use 3.14 for π.)
Nimfa-mama [501]
The\ volume\ of\ the\ cone:V_1=\frac{1}{3}\pi r^2 H\\(r-a\ radius;\ H-height)\\------------------\\r=7ft;\ H=7ft\\\\V_1=\frac{1}{3}\pi\cdot7^2\cdot7=\frac{1}{3}\pi\cdot343=\frac{343}{3}\pi\ (ft^2)\\-------------------\\The\ volume\ of\ the\ cylinder:V_2=\pi r^2 H\\(r-a\ radius;\ H-height)\\-------------------\\r=7ft;\ H=6ft\\\\V_2=\pi\cdot7^2\cdot6=294\pi\ (ft^3)\\------------------------\\The\ volume\ of\ the\ composite\ figure: V_F=V_1+V_2

V_F=\frac{343}{3}\pi+294\pi=\frac{343}{3}\pi+\frac{294\cdot3}{3}\pi=\frac{343}{3}\pi+\frac{882}{3}\pi=\boxed{\frac{1225}{3}\pi\ (ft^3)}\\\\\approx\frac{1225}{3}\cdot3.14}=\frac{3846.5}{3}\approx\boxed{1,282.17\ (ft^3)}\leftarrow answer

25POINTS!!!
Anastasy [175]

i. Let t be the line tangent at point J. We know that a tangent line at a  point on a circle, is perpendicular to the diameter comprising that certain point.

So t is perpendicular to JL


let l be the tangent line through L. Then l is perpendicular to JL

 

ii. So t and l are 2 different lines, both perpendicular to line JL.


2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.


Remark. Draw a picture to check the steps

8. Find the value of k, if (1-1) is a solution of the equation 3x-ky =8. Also, find the coordinates of
Yakvenalex [24]

Answer:

k = 5 and (6,2).

Step-by-step explanation:

Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.

Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.

So, 3(1) - k(-1) = 8

⇒ 3 + k = 8

⇒ k = 5 (Answer)

Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)

Now, putting x = 6 , then from equation (1) we get y = 2

Therefore, (6,2) is also a point on the graph of equation (1). (Answer)
