Answer:
D) Prime
Note that a number whose square root is to be found should not contain a negative sign and if necessary the negative sign should be replaced with "I" which means prime
Step-by-step explanation:
A good look at the photo attached will provide the necessary explanation
$5.12
Each pie requires 1/2 a cup of lemon juice, you make 2 pies so you need a cup of lemon juice. There are 16 tbsp to a cup, each lemon has 2 tbsps of juice, so you’ll need 8 lemons. Each lemon cost $0.64
8*0.64= $5.12

Answer:
Step-by-step explanation:
Decay is defined by the function as,
f(t) = ![(1-\frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=%281-%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
Here, r = rate of decay
t = duration of decay Or time (In years)
n = Number of times of decay in a year
Decay every 2 years over a period of t years,
f(t) = ![(1-\frac{r}{\frac{1}{2}})^{\frac{1}{2}\times t}](https://tex.z-dn.net/?f=%281-%5Cfrac%7Br%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20t%7D)
= ![(1-2r)^\frac{t}{2}](https://tex.z-dn.net/?f=%281-2r%29%5E%5Cfrac%7Bt%7D%7B2%7D)
Therefore,
will be the answer.
Decay 2 times a year over a period of t years,
f(t) = ![(1-\frac{r}{2})^{2t}](https://tex.z-dn.net/?f=%281-%5Cfrac%7Br%7D%7B2%7D%29%5E%7B2t%7D)
Therefore,
will be the answer.
Decay once per year over a period of t years,
f(t) = ![(1-\frac{r}{1})^t](https://tex.z-dn.net/?f=%281-%5Cfrac%7Br%7D%7B1%7D%29%5Et)
=
Therefore,
will be the answer.
Answer:
y + 5 = -2(x - 7)
Step-by-step explanation:
The slope of the line y = (1/2)x + 4 is 1/2. Any line perpendicular to this one will have a slope which is the negative reciprocal of 1/2: -2.
Using the point-slope form, the desired equation is:
y + 5 = -2(x - 7)
