To find the midpoint, we first add the points of the x values (-1 and 3), which is 2. Divide that by 2 to get 1 as our x value. Repeat for the y values to get (8+4)/2=6 and our midpoint is (1, 6)
Answer:
a) 55 degrees
b) 350 ft.
Step-by-step explanation:
a- the sum of angles of triangle=180
( since it is right angle , one angle is 90 degrees), x be the acute angle
x+35+90=180
x=180-125
x=55 degrees
b) tan 35= height of a tree/ length of a shadow
height of a tree=tan35*500=350.103≅350 ft ( rounded to nearest tens)
c) hypotenuse²=350.1²+500²
c=√350.1²+500²
c=610.385 ft
d) no because the distance is more than 500
The answer is 3.
You're welcome
Answer:
The coordinates are (-7sqrt(3)/2, 7/2).
Step-by-step explanation:
The rectangular coordinates from polar coordinates is found by:
x = r*cos(theta)
y = r*sin(theta)
Substituting the given values, we get:
x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2
y = 7*sin(150 deg) = 7*(1/2) = 7/2
The coordinates are (-7sqrt(3)/2, 7/2).
I hope this helps! :)
Answer:
an = 0.5^n−1
Step-by-step explanation:
Use the formula :
a_n = a_1r^n−1
To identify the geometric sequence.
an = 0.5^n−1
