A number N divides each of 17 and 30 with the same remainder in each case. What is the largest value N can have?
The equivalence of the remainder following the division of 17 and 30 by N indicates that the largest value N can have is 30
What is remainder in a division operation?The remainder term in a division of one value by a second value is the value which is less than the divisor, remaining after the divisor divides the dividend by a number of times indicated by the quotient.
The remainder following the division of 17 and 30 by the number N are the same.
Let R represent the remainder following the division of the integers 17 and 30 and let b represent the number of times N divides 30 than 17. Using the long division formula, we get;
17/N = Q + R/17
30/N = b·Q + R/17
30/N - 17/N = 13/N
The substitution property indicates that we get the following equation;
30/N - 17/N = b·Q + R/17 - (Q + R/17) = b·Q - Q
30/N - 17/N = b·Q - Q
13/N = b·Q - Q = (b - 1)·Q
13/N = (b - 1)·Q
The fraction 13/N which is equivalent to the product of (b - 1) and Q indicates that N is a factor of 13
13 is a prime number, therefore, the factors of 13 are 13 and N

a cypress beam found in the tomb of sneferu in egypt contained 55% of the amount of carbon-14 found in living cypress wood. estimate the age of the tomb given that carbon-14 has a half-life of 5730 years.
The estimated age of the tomb of Sneferu is 8,330 years.
The age of the tomb can be estimated using the carbon-14 decay equation, which states that the amount of carbon-14 remaining after time t (in years) is equal to the initial amount of carbon-14 multiplied by 0.5^(t/5730).The decay equation for carbon-14 is A = A₀e⁻kt, where A₀ is the original amount of carbon-14, A is the amount of carbon-14 at time t, k is the decay constant, and t is the amount of time that has passed.
We can rearrange the equation to solve for t: t = -ln(A/A₀)/k. In this equation, A is the amount of carbon-14 found in the cypress beam, and A₀ is the amount of carbon-14 found in living cypress wood.
In this case, the initial amount of carbon-14 was 100%, and the remaining amount was 55%. Solving for t, we get t = (ln(55%)/ln(0.5))*5730 = 8,330 years.
Therefore, the estimated age of the tomb of Sneferu is 8,330 years.

what is the equation of the line that passes through the point (−1,1)(−1,1) and has a slope of 5?
Answer:
The equation of a line can be represented in the slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept.
Given that the line has a slope of 5 and passes through the point (-1,1) we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1)
The point (-1,1) can be plugged into the equation:
y - 1 = 5(x + 1)
By simplifying and re-arranging the equation, we get:
y = 5x + 6
So the equation of the line that passes through the point (-1,1) and has a slope of 5 is: y = 5x + 6
Answer:
y = 5x+6
Step-by-step explanation:
Using the slope-intercept form of a line
y = mx+b where m is the slope and b is the y-intercept
y = 5x+b
Substitute the point into the line.
1 = 5(-1) +b
1+5 = b
6=b
The equation is
y = 5x+6

The line of linear equation y = 8x - 48 is much steeper than the line of linear equation y = -x - 4-.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The table of input and output values are given for the function.
The slope-intercept form of an equation/function is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
[16 - 32]/[8 - 10]
(-16)/(-2)
8
So, the slope point is obtained as m = 8.
The equation becomes - y = 8x + b
To find the value of b substitute the values of x and y in the equation -
32 = 8(10) + b
32 = 80 + b
b = 32 - 80
b = -48
So, the value for b is -48.
Now, the equation becomes -
y = 8x - 48
A graph has been plotted for the equation.
Similarly, the points for a line is given as (-6,2) and (-9,5).
The slope-intercept form of an equation/function is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
[5 - 2]/[-9 - (-6)]
(3)/(-9 + 6)
3/-3
-1
So, the slope point is obtained as m = -1.
The equation becomes - y = -x + b
To find the value of b substitute the values of x and y in the equation -
2 = -(-6) + b
2 = 6 + b
b = 2 - 6
b = -4
So, the value for b is -4.
Now, the equation becomes -
y = -x - 4
A graph has been plotted for the equation.
It is known that the larger the slope the steeper the line.
In the graph also it can be seen that the graph of line y = 8x - 48 is much steeper.
Therefore, the slope of line y = 8x - 48 is more steeper.

Answer:
Step-by-step explanation:
The result of 20 · 34 is 680, and the result of 20 ÷ 34 is approximately 0.588235294117647. Therefore, 20 · 34 is greater than 20 ÷ 34.The symbol "·" is used for multiplication, and the symbol "÷" is used for division. When we multiply 20 and 34, we are finding the total value of 20 items that are each worth 34. While when we divide 20 by 34, we are finding out how many times 34 can fit into 20, which is less than one.In short, Multiplication gives a bigger value than division, that's why 20*34 is greater than 20/34.

______
680
34 x 20 = 680
Now, divide 20 by 34
20/34 = 10/17
10/17 is less than 1, while 680 is much greater than 1.
680 > 10/17
20 x 34 is greater than 20 divided by 34

If u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), use Formula 5 of this theorem to find d/dt [u (t) x v (t). (3t sin(3 t) - cos(3 t) + 3cos(6 t), 3t- 3 sin(6 t), 3 t sin(3 t) - cos(3 t)
If u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), the derivative of cross product d/dt [u (t) x v (t)] is (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t)).
Formula 5 of the cross product theorem states that the derivative of the cross product of two vectors u and v is equal to the cross product of the derivatives of u and v:
d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt)
Where u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), we can find the derivatives as follows:
du/dt = (d(sin 3t)/dt, d(cos 3t)/dt, dt/dt)
= (3 cos 3t, -3 sin 3t, 1)
dv/dt = (dt/dt, d( cos 3t) /dt, d( sin 3t)/dt)
= (1, -3 sin 3t, 3 cos 3t)
Now, we can substitute these derivatives into the formula to find d/dt [u (t) x v (t)]:
d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt) = (3 cos 3t, -3 sin 3t, 1) x (t, cos 3t, sin 3t) + (sin 3t, cos 3t, t) x (1, -3 sin 3t, 3 cos 3t)
= (-3sin²3t - cos3t, t - 3cos3tsin3t, 3cos²3t + 3tsin3t) + (3cos²3t + 3tsin3t, t - 3cos3tsin3t, -3sin²3t - cos3t)
= (3cos²3t + 3tsin3t - 3sin²3t - cos3t, 2t - 6cos3tsin3t, 3cos²3t + 3tsin3t - 3sin²3t - cos3t)
= (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t))
The cross product of two vectors is a vector, and the result of the above calculation will be a vector that describes the rate of change of the cross product u(t) x v(t).
