A box weighing 8 newtons requires a force of 2 newtons to push it along the floor. ... A force of 30 N is executed to raise a rock weighing 90 N. The actual ...
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
the question has a slope of 1/3x with a y intercept of 2,
Thus, once the line reaches 9 in its y value, the x value would be 15
Answer:
y = 3x -4
Step-by-step explanation:
point slope form:
y - y1 = m(x-x1)
y-(-5) = 3(x-(-3))
y+5 = 3x + 9
y = 3x -4

see the attached figure to better understand the problem
we have that

Step 1
<u>Find the value of AC</u>
we know that
in the right triangle ABC

substitute the values in the formula

Step 2
<u>Find the value of BC</u>
we know that
in the right triangle ABC
Applying the Pythagorean Theorem

substitute the values

Step 3
<u>Find the value of BD</u>
we know that
in the right triangle BCD
Applying the Pythagorean Theorem

substitute the values


therefore
<u>the answer is</u>
the length of BD is 11.93 units
