Answer:
-4
Step-by-step explanation:
g(x) = -x - 3
To find g(1), replace x with 1 in the expression and evaluate it.
g(1) = -1 - 3
g(1) = -4
140
The area is lengthX width so (7+7)(5+5) which is just 14 x 10
Answer:
3 grams
Step-by-step explanation:
We are going to take the mass of a bunch of little strips below the triangle "roof." To do this, we must figure out what formula for the mass we'll use, in this case, we'll use:
Mass of strip = denisty * area = (1+x)*y*deltax grams
now, because the "roof" of the triangle contains two different integrals (it completely changes direction), we will use TWO integrals!
**pretend ∈ is the sum symbol
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral -1 to 0 of (1+x)*3*(x+1) = 3 * integral -1 to 0 of (x^2 + 2x + 1) = 3 * 1/3 = 1
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral 0 to 1 of (1+x)*3*(-x+1) = 3 * integral 0 to 1 of (-x^2 + 1) = 3 * 2/3 = 2
Total mass = mass left + mass right = 1 + 2 = 3 grams
Answer:
pethagoru
8^2 + 6^2= 100
pethagorus theory is a^2+b^2=c^2.
a^2 = base
b^2= side
c^2= hypotenuse
