Answer:

domain is [-3,3] & range is [-3,3]

Step-by-step explanation:

When given a graph of a circle and ask to solve range and domain....

First: <u>find the four points</u> of the circle:

(-3,0);(3,0);(0,-3);(0,3) . <em> **Best to plot these points on this graph to understand where the points are and what we are looking at.</em>

Second: Look for <u>range(vertical directions/left and right) and domain(horizontal direction/up and down)</u>.

domain: x-values, first coordinate (-3,0) & (3,0)

range: y-values, second coordinate (0,-3);(0,3)

Third: take what you know and solve domain and range*include bracket to show domain and range

domain is [-3,3] & range is [-3,3]

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola y=2−x2. What are the dimensions of su

Paul [167]

Answer:

Step-by-step explanation:

Given that a rectangle is inscribed with its base on the x-axis and its upper corners on the parabola

$y=2-x^2$

the parabola is open down with vertex at (0,2)

We can find that the rectangle also will be symmetrical about y axis.

Let the vertices on x axis by (p,0) and (-p,0)

Then other two vertices would be (p,2-p^2) (-p,2-p^2) because the vertices lie on the parabola and satisfy the parabola equation

Now width = $2-p^2$

Area = l*w = $2(2p-p^3)$

Use derivative test

I derivative = $2(2-3p^2)$

II derivative = $-12p$

Equate I derivative to 0 and consider positive value only since we want maximum

p = $\sqrt{\frac{2}{3} }$

Thus width= $\sqrt{\frac{2}{3} }$

Length = $2\sqrt{\frac{2}{3} }$

Width = $2-2/3 = 4/3$

) Una compañía invierte $15,000 al 8% y $22,000 al 9%. ¿A qué tasa debe invertir

Anna35 [415]

Usando proporciones, hay que los $12,000 restantes deben ser investidos a una tasa de 11%.

<h3>¿Qué es una proporción?</h3>

Una proporción es una fracción de la cantidad total.

De las dos primeras inversiones, el ingreso es dado por:

0.08 x 15000 = $1,200.

0.09 x 22000 = $1,980

T = 1200 + 1980 = $3,180

Por la tercera inversión, busca-se un retorno de 4500 - 3180 = $1,320.

De esa forma, la tasa x es la seguiente:

12000x = 1320

x = 1320/12000

x = 0.11.

Los $12,000 restantes deben ser investidos a una tasa de 11%.
