Answer: 15 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation to the sun, , the opposite side (x) is the height of the tree, and the adjacent side is the length of the shadow.
Replacing with the values given:
Tan 31 = x /25
Tan 31 (25) =x
x = 15 feet
Feel free to ask for more if needed or if you did not understand something.
Answer:
20mph
Step-by-step explanation:
because when you divide the 280 it goes by 20 mph to get to 280 miles by quarters but in 20s
-1/3
Use the formula m = y2-y1/ x2 - x1.
Substitute the x and y values and you'll get -1/3
Answer:
m = 60/6
60 = 6 x m
Step-by-step explanation:
Answer:
(0,0)
Step-by-step explanation:
Let's put this in standard form in our minds.
Standard form of a circle is (x-h)^2 + (y-k)^2 = r^2.
(h,k) is the center, and r is the radius.
x^2 + y^2 = 121
(x-0)^2 + (y-0)^2 = 121
We can just think about this like they have a secret 0 as the h and k! The center is just (0,0). Good luck in your math class:)
