Answer:

r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}

Step-by-step explanation:

25= r•r•8 ⇔ 25/8 = r²

then

r^{2} =(\frac{5}{2\sqrt{2} } )^{2} \\\\Then\\\\r = \frac{5}{2\sqrt{2} } \\Or\\r = -\frac{5}{2\sqrt{2}}

Answer:

Step-by-step explanation:

We have f(x) and g(x). We are to evaluate each of these functions at the domain values given (1, 2, 3, 4, 5, and 6) and see where the output is the same.

f(1)=-(1)^2+4(1)+12 and f(1) = 15

f(2)=-(2)^2+4(2)+12 and f(2) = 16

f(3)=-(3)^2+4(3)+12 and f(3) = 15

f(4)=-(4)^2+4(4)+12 and f(4) = 12

f(5)=-(5)^2+4(5)+12 and f(5) = 7

f(6)=-(6)^2+4(6)+12 and f(6) = 0

Now for g(x) at each of these domain values:

g(1) = 1 + 2 and g(1) = 3

g(2) = 2 + 2 and g(2) = 4

g(3) = 3 + 2 and g(3) = 5

g(4) = 4 = 2 and g(4) = 6

g(5) = 5 + 2 and g(5) = 7

g(6) = 6 + 2 and g(6) = 8

It looks like the outputs are the same at f(5) and g(5). Actually, the domains are the same as well! f(5) = g(5)

You open a book to two facing pages. The product of the two pages is 600. Find the page numbers.
Ivan
To find this, use an equation with x to represent the smaller page number as your variable. set up the equation x(x+1) = 600. distribute the x to get x^2 + x = 600. subtract 600 from both sides so you have x^2 + x - 600 = 0. factor to get (x+24)*(x+25) = 0. so the two pages are 24 and 25
