Answer:

Let a(x) represent the remaining balance on Hillary's gift card after buying x applications on her phone.

Given ⇒⇒⇒ a(x)=50-1.25xConsidering that x represents the number of apps bought on her phone

∴ a(12) = 50 - 1.25 * 12 = 35

This means her initial total funds were $50

She bought 12 apps costing a total of 12 *1.25 = 15. Thus, she spent $15

Her remaining balance on the gift card = 50 - 15 = 35

The final answer is:

a(12) =35.

This indicates that after acquiring 12 apps, Hillary retains $35

Answer: \frac{1}{36}\pi L

Step-by-step explanation:

The volume of a cylinder is calculated using the formula:

V=\pi r^2h

In which "r" represents the radius and "h" is the height.

Convert inches to feet. Given that 1\ ft=12\ in, the result is:

(2\ in)(\frac{1\ ft}{12\ in})=\frac{1}{6}\ ft

Therefore, you can determine:

r=\frac{1}{6}\\\\h=L

After substituting these values into the formula and simplifying, the result is:

V=\pi(\frac{1}{6})^2L\\\\V=\frac{1}{36}\pi L

Consequently, the equation representing the volume of L feet of drainage tubing, in cubic feet, is:

\frac{1}{36}\pi L

Find the cube root of 10 upto 5 signaficant figures by newton raphson method
AnnZ [12381]

Answer: The cube root of 10 is 2.1544, using an initial value of -0.003723.

Step-by-step explanation: The Newton-Raphson method is utilized for root finding, and its formula is NR: X=Xo-(f(x)/f'(x)). Before applying this formula, the derivative of the equation must be determined. Given that X =10, this method was implemented to identify the best root to ascertain the cube root of 10 to 5 significant figures. Utilizing software like Excel for quicker iteration calculations is advisable. The found root in this instance was -0.003723.
