Hello,
Let's x the side of the triangle:
x²-x²/4=7²
==>3/4x²=49
==>x=14/√3
Area= 14/√3 * 7/2 =49√3 /3≈28,29016...
The answer is 0.375 miles
Answer:
v = -3i - 2j
Step-by-step explanation:
Vector given two points:
Given two points, a vector is the subtraction of the terminal point by the initial point.
In this question:
Initial point: (-1, 4)
Terminal point: (-4, 2)
So
v = (-4,2) - (-1, 4) = (-4 - (-1), 2 - 4) = (-3,-2)
The vector is v = (-3,-2)
In component form:
xvalue is i, yvalue j. So
v = -3i - 2j
Answer:
37

Unfortunately, you haven't shared the instructions for this problem. My guess is that you are to evaluate <span>P(x)= x^3+4x^2-8x-6 for x = a = -2.
If that's the case, then
P(-2) = (-2)^3 + 4(-2)^2 - 8(-2) - 6. This simplifies to:
= -8 + 16 + 16 - 6 = 18 (answer)</span>
