there is no triangle drawn
Answer: the height of the flagpole is 21 ft
Step-by-step explanation:
Since the angle of elevation to the top of the flagpole is 40°, a right angle triangle is formed. The height of the flagpole represents the opposite side of the right angle triangle. Your distance from the base of the flagpole represents the adjacent side of the right angle triangle. Therefore, to determine the height of the flagpole, x ,we would apply the tangent trigonometric ratio which is expressed as
Tan θ = opposite side/adjacent side
Tan 40 = x/25
x = 25tan40 = 25 × 0.8391
x = 20.98
x = 21.0 ft to the nearest tenth.
Answer:
x=8
Step-by-step explanation:
normally it would be 2x-1=
x+9 so now we have to combine the x into one fraction which will be 2x-1=
+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=
+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped
Answer:
See below in bold.
Step-by-step explanation:
A. (x + 7)^2 + (y - 7)^2 = 10.
This is the equation of a circle.
It is NOT a function
One to many correspondence.
B. y = x^2 + 2x - 3
This is a parabola which opens upwards.
It is a function.
For 2 values of x ( except at the vertex) there is one value of y so it is
many to one correspondence.
Answer:
x = 9.5
x = 9 1/2
x = 19/2
All answers are the same, just different ways of denoting it.
Step-by-step explanation:
-4 + 5x - 7 = 10 + 3x - 2
Simplify both sides, by combining like terms
-4 + 5x - 7 = 10 + 3x - 2
-11 + 5x = 8 + 3x
Inverse operations
-11 + 5x = 8 + 3x
+11 +11
5x = 19 + 3x
-3x -3x
2x = 19
/2 /2
x = 9.5
