horizontal stretch
Step-by-step explanation:
By looking at the attached image, you can easily determine what does what by comparing the functions to the graph.
Ok so the answer in here is <span>60 grams of the alloy with 10% of titanium needed and 40 grams of the alloy with 25% of titanium are needed.
Let me explain it to you
</span>let x = grams of alloy A and y = grams of alloy B.
x + y = 100
which is
mass of A + mass of B = 100
and
0.15x + 0.20y = 0.17*100
which is
fractionA*massA + fractionB*massB = fractionTotal*massTotal
<span>0.15(100 - y) + 0.20y = 17
15 - 0.15y + 0.20y = 17
0.05y = 2
y = 40 grams
x = 100 - y = 60 grams</span>

Answer: True</h3>
A negative velocity means the object is going the opposite way of the positive direction. So a negative x component velocity is pointing the opposite way (left) of the positive direction (right). You can think of it as the cart is backing up as it faces the positive direction.
