Answer:
the distance between them is decreasing at a rate of 2 mph.
Step-by-step explanation:
List all given rates and the unknown rate.
Write the formula that relates the variables in the problem: x, y, and s.
There’s a right triangle in the diagram, so you use the Pythagorean Theorem:
For this problem, x and y are the legs of the right triangle, and s is the hypotenuse, so
Differentiate with respect to t.
Use the Pythagorean Theorem again to solve for s.
x = 0.4
y = 0.3
You can reject the negative answer because s obviously has a positive length. So s = 0.5.
Now you’ve got everything you need to substitute into the differentiation result and solve for ds/dt.
This negative answer means that the distance, s, is decreasing. Thus, when car A is 3 blocks north of the intersection and car B is 4 blocks east of the intersection, the distance between them is decreasing at a rate of 2 mph.
Answer:
Step-by-step explanation:
We can simplify this inequality by isolating x on one side.
.
Let's add 36 to both sides.
Hope this helped!
Just for an example, lets say you'd have to solve 35 ÷ 7.
First, the first number always goes inside the┌ (I'll call it "the house") The first number, of course, is 35 in this case.
Second, the second number goes on the outside of "the house" on the left. Of course, the 7 is the second number in this case.
Third, now that you've set up the problem, now you can solve it!
Compare the number on the outside of the house to the first digit on the inside of the house. In this case, that's 7 and 3. Since 7 doesn't go into 3, you move on to the next number that's inside the house, 5. In other words, now you're comparing 7 to 35.
7 goes into 35 5 times, so now you'd put a 5 on top of the house above the 5 in 35!
35 ÷ 7 = 5!
• I hope this was helpful! Sorry it was long, but I was just trying to thoroughly explain it! •
The answer is x=-14
Here's why:
7 times -2= -14
(A negative times a positive equals a negative)
-14 divided by 7=-2
(A negative divided by a positive equals a negative)
-14/7=-2
X=-14
