Answer:
77 feet
Step-by-step explanation:
ratio
3:7=33:x
33/3=11
7*11=77
77 feet
We know that
If the scalar product of two vectors<span> is zero, both vectors are </span><span>orthogonal
</span><span>A. (-2,5)
</span>(-2,5)*(1,5)-------> -2*1+5*5=23-----------> <span>are not orthogonal
</span><span>B. (10,-2)
</span>(10,-2)*(1,5)-------> 10*1-2*5=0-----------> are orthogonal
<span>C. (-1,-5)
</span>(-1,-5)*(1,5)-------> -1*1-5*5=-26-----------> are not orthogonal
<span>D. (-5,1)
</span>(-5,1)*(1,5)-------> -5*1+1*5=0-----------> are orthogonal
the answer is
B. (10,-2) and D. (-5,1) are orthogonal to (1,5)
Answer:
acute and isosceles
Step-by-step explanation:
acute because all angles less than 90
isosceles because 2 sides are equal length
This would be 400%. To get a percent you multiply the number by 100. For example, .62 x 100 equals 62%.
Answer:
3v + 5u
Step-by-step explanation:
Write z = y^3 x^5 in terms of u and v.
Take the natural log (ln) of both sides. Then:
ln z = 3 ln y + 5 ln x
Substituting u for ln x and v for ln y, we get:
ln z = 3v + 5u (answer)
