The height will approximately be 3 to 3.6 feet

A reasonable estimate could be any number that makes sense. Say the average elementary student is 4' 10" then a reasonable estimate could be 3' to 3' 6" because the desk would be about a 1' 6" shorter than the person.

At which values of X does the function F(x) have a vertical asymptote check all apply F(x) =3/(x+2) (x-7)

finlep [7]

Answer:

When x = -2 or when x = 7

Step-by-step explanation:

x+2 is a factor in the denominator. If x = -2, the factor becomes zero.

x-7 is a factor in the denominator. If x = 7, the factor becomes zero.

We can't have zero as a factor in a denominator because division by zero is not defined. It doesn't have any meaning.

Help !! Please I can’t find the answer

SVETLANKA909090 [29]

Answer:

$\large\boxed{r^2=(x+5)^2+(y-4)^2}$

Step-by-step explanation:

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have diameter endpoints.

Half the length of the diameter is the length of the radius.

The center of the diameter is the center of the circle.

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the given points (-8, 2) and (-2, 6):

$d=\sqrt{(6-2)^2+(-2-(-8))^2}=\sqrt{4^2+6^2}=\sqrt{16+36}=\sqrt{52}$

The radius:

$r=\dfrac{d}{2}\to r=\dfrac{\sqrt{52}}{2}$

The formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

Substitute:

$x=\dfrac{-8+(-2)}{2}=\dfrac{-10}{2}=-5\\\\y=\dfrac{2+6}{2}=\dfrac{8}{2}=4$

$(-5,\ 4)\to h=-5,\ k=4$

Finally:

$(x-(-5))^2+(y-4)^2=\left(\dfrac{\sqrt{52}}{2}\right)^2\\\\(x+5)^2+(y-4)^2=\dfrac{52}{4}\\\\(x+5)^2+(y-4)^2=13$

The image below shows the graph of a sound recorded on an oscilloscope. What are the period and the amplitude? (Each unit on the

Serhud [2]

Remember that the period of a sinusoidal function is the vertical distance between the t-axis and one of the extreme points. From the graph we can infer that the period of the function is 4.5.

Also, the amplitude is the distance between two consecutive maximum or two consecutive minimum points. From the graph we can infer that the amplitude of the function is 0.05 seconds.

We can conclude that the correct answer is: 0.05 seconds; 4.5
