Answer:

$\displaystyle y = -4 - x \\ -1 = m$

Step-by-step explanation:

$\displaystyle \frac{-3y}{-3} = \frac{12 + 3x}{-3} \\ \\ y = -x - 4$

* In the Slope-Intercept Formula [y = mx + b], b represents the y-intercept, and the rate of change [slope] is represented by m.

I am joyous to assist you anytime.

Step-by-step explanation:

-3y=12+3x

-y=4+x

y=-4-x and m which is the gradient is the coefficient of x which is -1, therefore m=-1

Step-by-step explanation:

You have a half sphere and a cylinder.

Trick question! Note that the diameter of the cylinder is in meters, while the height is given in centimeters.

For cylinder:

radius r = 5 m

height h = 6 cm = 0.06 m

volume = πr²h = π(5²)(0.06) = 1.5π m³

For sphere:

radius r = 5 m

volume of sphere = (4/3)πr³

volume of half sphere = (2/3)πr³ = (2/3)π5³ = (250/3)π m³

Total volume = 1.5π + 250π/3 ≅ 266.5 m³

in a AP the first term is 8,nth term is 33 and sum to first n terms is 123.Find n and common difference

allsm [11]

I believe there is no such AP...

Recursively, this sequence is supposed to be given by

$\begin{cases}a_1=8\\a_k=a_{k-1}+d&\text{for }k>1\end{cases}$

so that

$a_k=a_{k-1}+d=a_{k-2}+2d=\cdots=a_1+(k-1)d$

$a_n=a_1+(n-1)d$

$33=8+(n-1)d$

$21=(n-1)d$

$n$ has to be an integer, which means there are 4 possible cases.

Case 1: $n-1=1$ and $d=21$ . But

$\displaystyle\sum_{k=1}^2(8+21(k-1))=37\neq123$

Case 2: $n-1=21$ and $d=1$ . But

$\displaystyle\sum_{k=1}^{22}(8+1(k-1))=407\neq123$

Case 3: $n-1=3$ and $d=7$ . But

$\displaystyle\sum_{k=1}^4(8+7(k-1))=74\neq123$

Case 4: $n-1=7$ and $d=3$ . But

$\displaystyle\sum_{k=1}^8(8+3(k-1))=148\neq123$
