Hello : 
q(r)=3<span>√(r²-16)
q  exist : r² - 16 </span><span>≥ 0
r² </span><span>≥ 16
</span>√r² ≥ √16
but :  √16 = 4    and  √r² = <span>|r |
</span>|r | ≥ 4
r ≤ 4 or  r  ≥ 4 
the domain is :  ] -∞, 4] ∪  [,4 , + ∞ [

Please help I don’t wanna add a bunch of points Bc nobody is helping me I’m just wasting them.
Ede4ka [16]

Answer:Cross multiply and solve for x.

x/6 = 5/1.25

let the height of building be h ft

h/6 = 60/15

h = 6(60/15) = 24

the building is 24 ft high

Step-by-step explanation:

Well first let’s covert the ft to in- 5ft is 60 in and 6ft is 72 in. Then we want to set up 2 fractions based on height and shadow, so we have 60/15=x/72 (we put x because that’s what we’re trying to find). Then we do cross multiplication so now we have 15x=4320. We divide 15, so now we have 4320/15=288. So the building is 288 in tall or 24ft tall! Glad to help! :)

grandymaker [24]

Answer: D


Step-by-step explanation:


Isosceles Triangle has 3 sides, that has 2 sides of equal length.

Equilateral Triangle has 3 sides, that has 3 sides all of equal length.

If you have heard of the Hypotenuse, it has 3 sides of all different lengths maybe that's what this? But, the answer would indeed be D. Form Neither an equilateral nor an isosceles triangle.



 Happy Mathing!!

Write an equation in slope-intercept form of the line shown.
tankabanditka [31]

Answer:

y = 3/4x - 2

Step-by-step explanation:

slope intercept form: y = mx + b

y-intercept(when x= 0) is given by b

slope is given by m

lets find the slope using the two given points, (4,1) and (8,4)

m = y2-y1 / x2-x1

m = 4 - 1 / 8 - 4

m = 3/4

Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).

1 = 3/4(4) - b

1 = 3 - b

b = -2

now you have m and b so you can finish writing your equation.

y = mx + b

y = 3/4x - 2

Write how many hundred thousands, ten thousands, and thousands there are in the numbers of acres of Land Big Bend National Park
sveta [45]

To solve this problem, we must remember our place values. 100,000 represents hundred thousands, 10,000 represents ten thousands, and 1,000 represents thousands similarly to how 100 represents hundreds, 10 represents tens, and 1 represents ones. Using this knowledge, we know that the number 8 is in the hundred thousands place, the number 0 is in the ten thousands place, and the number 1 is in the thousands place.

This means that there are 8 hundred thousands, 0 ten thousands, and 1 thousand in the number of acres of land the National Park owns.

Hope this helps!
