Si estas haciendo una linea recta vas a necesitar dos puntos. Los encuentras poniendo un numero por x en la formula para que te de un numero, y. Y te va dar (x, y). Lo haces otravez con otro valor de x y ese te va dar (x2, y2). Y luego los conectas con una linea.

What is the area of a semi circle that has a diameter of 1 1/2?

SVEN [57.7K]

Answer:

$A=0.8836$

Step-by-step explanation:

Area of circle:

$\pi r^2$

By using the area of a circle, we can get the area of a semicircle:

$\frac{\pi r^2}{2}$

Let's convert the mixed fraction to an improper fraction and then a decimal:

$1\frac{1}{2}$ = $\frac{3}{2}$ = $1.5$

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

$\frac{1.5}{2} =0.75$

Now we have the radius, so we can plug in our values and find the area:

$\frac{\pi0.75^2}{2} = 0.88357293$

$A=0.88357293$

Food costs are expected to rise 6% each month for the next year. Which series correctly depicts the cost (to the nearest cent) f

alexira [117]

For this case we have the following equation:
y = 150 * (1.06) ^ t
For the first month we have:
y = 150 * (1.06) ^ 1
y = 159 $
For the second month we have:
y = 150 * (1.06) ^ 2
y = 168.54 $
For the third month we have:
y = 150 * (1.06) ^ 1
y = 178.65 $
Answer:
d. $ 159.00 + $ 168.54 + $ 178.65
