Answer:
[tex]h'(x) = -x + 5[/tex]
Step-by-step explanation:
Given
[tex]h(x) = -x+ 5[/tex]
Required
Determine the inverse
[tex]h(x) = -x+ 5[/tex]
Replace h(x) with y
[tex]y = -x+ 5[/tex]
Swap positions of x and y
[tex]x = -y+ 5[/tex]
Make y the subject
[tex]y = -x + 5[/tex]
Replace y with h'(x)
[tex]h'(x) = -x + 5[/tex]
An airplane takes off 200 yards in front of a 60 foot building. At what angle of elevation must the plane
take off in order to avoid crashing into the building?
Answer:
16.69°
Step-by-step explanation:
Given that,
Height of the building, h = 60 foot
Distance from the base of the building, b = 60 foot
We need to find the angle of elevation must the plane takes off in order to avoid crashing into the building. So,
[tex]\tan\theta=\dfrac{60}{200}\\\\\theta=\tan^{-1}\dfrac{60}{200}\\\\=16.69^{\circ}[/tex]
So, the required angle is 16.69°.

Olivia writes an expression that is the sum of three terms.
The first term is the product of 2 and the sum of 4 and n.
The second term is 3 squared times n.
The third term is the product of 4 and 2 less than n.
The expression is equal to 30.
What is n?
Answer:
n= 2
2 x 6= 12
9x2=18
4x0=0
12+18+0=30

Solve |3x – 2| = |x + 1| Question 12 options: A) x = 3∕2 or x = 1∕4 B) No solutions C) x = 3 or x = –4 D) x = 1∕4
Answer:
x = 3/2
Step-by-step explanation:
Step (1) :
We should put like term togther:
3x - x = 2 +1
2x = 3
Step (2) :
Divide bothe side by 2:
2x/2 = 3/2
x = 3/2

Michela is training for a race. She runs 5 miles in 52 minutes. Her goal is to run 6 miles in 1 hour. By how many minutes per mile must Michela decrease the rate to meet her goal? explain your reasoning.
Answer:
.4
Step-by-step explanation:
52/ /4= 10.4
60/6=10
10.4-10=.4
Michela needs to increase her speed by 0.23 miles/hour to attain her goal.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
She runs 5 miles in 52 minutes.
5 miles in (52/60) hour
In 1 hour → 5(60/52) = 300/52 = 5.769
Her goal was 6 miles in 1 hour.
5.769 + x = 6
x = 0.23 miles/hour
Hence "Michela needs to increase her speed by 0.23 miles/hour to attain her goal".

9514 1404 393
Answer:
x ≈ 7.00
y ≈ 12.21
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships ...
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
Translated to the figure at hand, these are ...
cos(35°) = 10/y ⇒ y = 10/cos(35°) ≈ 12.21
tan(35°) = x/10 ⇒ x = 10·tan(35°) ≈ 7.00

Answer:
20
Step-by-step explanation:
The two angles shown are complementary. The corner angles in a rectangle are right angles: 90°.
(4x -12) +(x +2) = 90
5x = 100 . . . . . . collect terms, add 10
x = 20 . . . . . . . . divide by 5
A right triangle is shown with an angle that measures 60 degrees. The leg adjacent to the 60 degree angle is labeled 5. The leg opposite of the 60 degree angle is labeled x. The hypotenuse is labeled 10. Find the value of x. If your answer is not an integer, leave it in simplest radical form. The diagram is not drawn to scale.

what is the recursive formula of the geometric sequence 1/2,3/4,9/8,27/16
Answer:
Step-by-step explanation:
A recursive geometric formula has the pattern:
[tex]A_n=A_{n-1}*r[/tex] where r is the common ratio. Before we write the formula, we need to find the value for r. This r value has to be the same between each consecutive number in the series. Because it's geometric, r is multiplied in (whereas it's added in if the sequence is arithmetic). To get from 1/2 to 3/4 we find the r value in this way:
[tex]\frac{x}{2}=\frac{3}{4}[/tex] where x/2 is the same as 1/2 x. Cross multiply to get 4x = 6 and x = 3/2. That means that if r is 3/2, then we can multiply every term in that sequence by 3/2 to get to the next term in line. 3/4 times 32 is 9/8. Therefore, r = 3/2 and the formula will be:
[tex]A_n=A_{n-1}*\frac{3}{2}[/tex]
