The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.

<h3>How to find the numeric value of an expression?</h3>


The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.

For this problem, the expression is given by:

d² + 3a + 6 + a

We want to find the numeric value when a = 2 and d = 5, hence:

5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.

Find the circumference of a circle whose area is 24 pi ft ^2
lianna [129]
\bf \textit{area of a circle}\\\\&#10;A=\pi r^2~~&#10;\begin{cases}&#10;r=radius\\&#10;-----\\&#10;A=24\pi &#10;\end{cases}\implies 24\pi =\pi r^2\implies \cfrac{24\pi }{\pi }=r^2&#10;\\\\\\&#10;24=r^2\implies \boxed{\sqrt{24}=r}\\\\&#10;-------------------------------\\\\&#10;\textit{circumference of a circle}\\\\&#10;C=2\pi r\qquad \qquad \implies C=2\pi\left( \boxed{\sqrt{24}} \right)~~&#10;\begin{cases}&#10;24=2\cdot 2\cdot 2\cdot 3\\&#10;\qquad 2^2\cdot 6&#10;\end{cases}&#10;\\\\\\&#10;C=2\pi \sqrt{2^2\cdot 6}\implies C=2\pi (2\sqrt{6})\implies C=4\sqrt{6}~\pi

The y intercept is what the y value is when x is 0.

Set X to 0 and solve:

-2/9(0) + 1/3

0 + 1/3 = 1/3

The y-intercept is 1/3

\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Given :}}} \\

  • Mass (M) of space shuttle = 1.0 × 105 kg.
  • Altitude (r) = 200.0 km

\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: To \: \:   Find  :}}} \\

  • The force of gravity that the space shuttle experiences = ?

\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Solution :}}} \\ \\

\purple{\maltese}\large\underline{\underline{\sf\:\: using \: formula :}} \\ \\

\bigstar \: \underline{ \boxed{\sf { \pink{g = \frac{G \: M}{{r }^{2} }}}}} \\  \\

\\ ❒\:  \: \underline{\textbf {Putting values \: in \: the \: \: given \: formula :}} \\

\sf \implies \: g = \frac{G \: M}{{r }^{2} }  \\

\sf \implies \: g = \frac{6.67×10^{-11} × 1.0×10^5}{(2×10^5)^{2} }  \\

\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}}\\

\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}} \\

\sf \implies \: g =1.6675×10^{-6-10}\\

\sf \implies \: g =1.6675×10^{-16}\: Newton\\\\

\:\:\:\:\:\:\:\qquad\rule{150pt}{2pt} \\\\

Henceforth, the force of gravity experienced by the shuttle is <u>1.6675×10^N</u>
