Factor 3x^2 minus 12x minus 36 Completely

Solve the formula C = πd for d

REY [17]

Answer:

$d = \frac{C}{\pi}$

Step-by-step explanation:

$C= \pi d\\$

Isolate d ; Divide both sides of the equation by $\pi$

$\frac{C}{\pi} = \frac{\pi d}{\pi }$

Simplify

$\frac{C}{\pi} = d\\\\d = \frac{C}{\pi}$

Note; Another formula for d(diameter) =

$2\times radius$

Answer:

-infinity

Step-by-step explanation:

plug in numbers for x that is on the right side of the graph and you will see a trend that the larger x is the bigger y is(technically smaller because y would be negative due to the negative sign outside the square root) as x approaches inifity y approaches negative infinity.

Question 18

ira [324]

Answer:

The function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Step-by-step explanation:

Given the sequence

$95, 80, 65, 50, ...$

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$80-95=-15,\:\quad \:65-80=-15,\:\quad \:50-65=-15$

As the difference is the same, so

$d = -15$

as

$a_1=95$

Thus, substituting $d = -15$ , $a_1=95$ in the nth term of an arithmetic sequence

$a_n=a_1+\left(n-1\right)d$

$a_n=-15\left(n-1\right)+95$

$a_n=-15n+110$

Therefore, the function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Compound interest formula

A=11700\hspace{35px}P=6900\hspace{35px}t=12\hspace{35px}n=365

A=11700P=6900t=12n=365

Given values
