Answer:
x=3
Step-by-step explanation:
Basically the question is asking what value of x gives the same value for y
(or where do the 2 lines cross)
the input is x=3, the out put is y =-1
The slope is 4/5 assuming time is along the bottom of the graph.
Answer:
The new dimensions of the field will be 44.8 feet by 19.6
Step-by-step explanation:
since the scale factor is 1.4, all the original dimensions are multiplied by 1.4
32 times 1.4 is 44.8 and 14 times 1.4 is 19.6
B is the answer to that question !!!
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)
