Answer:
y = 7/5x - 14 3/5
Step-by-step explanation:
Point-slope form:
y + 9 = 7/5(x - 4)
y + 9 = 7/5x - 28/5
y = 7/5x - 14 3/5
For this question, we need the formula τ = F x d<span>, and just plug the numbers in.
</span>
Given the formula <span>τ = F x d</span>
Where τ = torque,
F = force applied, &
d = distance from the axis / hinge,
<span>τ = 300 c 0.8 = 240Nm</span>
Disregard the weight of the door or if there's any friction at the hinge. None of this will change the torque applied.
Answer:
The tree is 17.5 ft tall
Step-by-step explanation:
We can use proportions to solve this.
Notice that Emily (5 feet tall) and her shadow (8 feet long) constitute the two legs of a right angle triangle (see attached image).
The nearby tree (unknown height H), will also cast a shadow (28 ft long) with the same inclination as Emily does due to the unique position of the sun relative to them.
Then we can use the proportion associated with the sides of similar triangles:

Then, we can solve for H in the equation:

The correct answer is C. One solution
To find the cost per week, divide the total cost by how many weeks you are signing up for.
Total cost / number of weeks = cost per week
$325 / 13 weeks = $25 per week
The cost per week is $25 for swimming lessons.
