side of the triangle =s
s²=(6√3)²+(s/2)²
solve for s
P=3s-The altitude divides the equilateral triangle into two 30-60-90 triangles.
The sides of the 30-60-90 t
Write an equation for a horizontal line that includes the point (2,-3)-The equation of a horizontal line is y = (number).
In this case the y coordinate of (2, -3) is -3.
So the equation must be y = -3
How do you solve the following limits algebrically?
Lim X----->0(-1/(3+x)+1/3)/ (x)
Lim h----->0((x+h)^2+(x+h))-(X^2+x)/h-to solve algebraically, simplify the fractions first
1) [ -1/(3+x)+(1/3)]/

How do you find the inverse of 4e^kt=y?
Thank you for your time-Let f(t) = y and g(y) = t
ie g is inverse of f
y = 4e^(kt)
y/4 = e^(kt)
ln (y/4) = kt
t = (1/k) ln (y/4)
g(y) = (1/k) ln (y/4)
g(t) = (1
To find circumference and area knowing that the radius is 5.2, you have to use the formula of circumference and area of a circle. For circumference, you plug 5.2 as r in C=2(pi)(r), which would be C=2
About to start school, forgot how to do this:
8mn-10n+12m-15-factor by grouping...
8mn - 10n + 12m - 15
(8mn - 10n) + (12m - 15)
pull out the GCF of each pair
2n(4m - 5) + 3(4m - 5)
pull out the c
Like when we cut a cake in half its not possible for us to cut it literally down to the atomic level in half is it? so when we say we are going to cut a cake in half we are making an approximation are
How do I do this?
i have a right triangle the is angle a, b, and c.
The hypotenuse is 25, the opposite is 7, and the adjacent is 24.
Secant is the opposite of cosine so on my calculator i put in cos^-
These are questions from my summer math assignment that I am having problems with. I have looked around online and in notes and cant figure out how to find the domain of each of these functions. Pleas
Find the value of rs/t+st/r+tr/s where r,s, and t are the roots of the equation x^3-5x^2+6x-9=0.I think it has something to do with Vietas formulas, but I cant easily manipulate the product or some to
The Parabola P has equation y =- x ^ 2 +2 x-3 and the function f has the rule f (x) = 2x ^ 2-8x + ka) Determine the intersection between P and f
b) Determine k so that the graphs of f and P has exactl
When you are finding the domain of a function that is a fraction such as (x-2)/(x+4), do you have to do anything with the top of the fraction or can you just ignore it since you can have anything but
f(x)=x^2+2x+1
g(x)= 3x+3
Could you show me how to do this? thanks!-Just set them equal then solve the resulting equation:
x² + 2x + 1 = 3x + 3
x² - x - 2 = 0
(x + 1)(x - 2) = 0
x + 1 = 0 OR x - 2 = 0
Evaluate the function at the given value of the independent variable and simplify.
f(x) = 7x - 2; f(0)
FIVE STARS TO FIRST BEST ANSWER (:-f(0) = 7(0) - 2
= 0 - 2
= -2
just replace x with 0.-If f(
