Answer: To find the inverse, interchange the variables and solve for y.
Step-by-step explanation:
f-^1 (x)= - 5x/3
Answer:
Angle 2 = 105
Step-by-step explanation:
Since these angles are cut by a transversal the angle from above is congruent to angle #2. You can say the theorem that is used to make these two congruent is the Alternate exterior angles theorem which states this.
Hope this helped!
Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:
[Differentiate both sides w.r.t. t]
Put
Also, 
i.e. height is maximum at t=7.
Maximum height = 
Hence, the maximum height the rocket reaches = 245 feet.
I would say about 40 kilometers it’s ifs 20 around her neighborhood that 20+20=40 and walking tha rest made the question easier but yea 40
Answer: s, v, w, & x = 13 y = 20 z = 20 + 13√3
<u>Step-by-step explanation:</u>
First, you need to understand the side lengths of each special triangle in the drawing.
A 45°- 45°- 90° triangle has corresponding sides of a - a - a√2
A 30°- 60°- 90° triangle has corresponding sides of b - b√3 - 2b
The hypotenuse of the 45-45-90 triangle is 13√2, so its legs are 13.
So A F = 13 → s = 13 and w = 13
FB = 13 → x = 13
EC = 13 → v = 13
Since the x-value of C is 20, then the x-value of E is also 20 → y = 20
ED is opposite of the 60° angle of the 30-60-90 triangle so ED is EC√3. Since EC = 13, then ED = 13√3.
AE + ED = AD
20 + 13√3 = AD → z = 20 + 13√3
