If the function h(t) = tan(5t +4 ) using chain rule we found values h'(1)= 6.02 and h"(1) = -27.24
What is chain rule for differentiation?Chain rule for differentiation states that the differentiation of the composition of two functions f, g
(fоg)' = f'(g(x))* g'(x) , where ' represents first derivative with respect to independent variable x .
For three functions : x, y, t
(x(y(z(t))))' = x'(y(z(t)))*(y'(z(t)))*z'(t)
Given h(x) = tan(5t+4)
Let f(t) = tan t and g(t) = 5t+4
f'(t) = sec² t and g'(t) = 5
Then h(t) = fоg(t)
Using chain rule of differentiation:
h'(t) = (fоg(t))' = f'(g(t))* g'(t) = sec²(5t+4) *(5) = 5 sec²(5t+4)
let x(t) = 5t², y(t) = sec(t), z(t) = 5t+4
x'(t) = 10t , y'(t) = sect tan t , z'(t) =5
(x(y(z(t))))' = x'(y(z(t)))*(y'(z(t)))*z'(t)
h"(t) =(x(y(z(t))))'= 10 sec(5x+4) * sec(5t+4)tan(5t+4)*5
h"(t) = 50sec²(5t+4)tan(5t+4)
The value of h'(t) at t =1
h'(1 ) = 5 sec²(5(1)+4)= 5 sec²(9) =6.02
h"(1) = 50sec²(5(1)+4)tan(5(1)+4) = 50sec²(9)tan(9) = -27.24
Therefore, the values h'(1 ) = 6.02 and h"(1) = -27.24

A process produces a certain part with a mean diameter of 3 inches and a standard deviation of 0.05 inches. The lower and upper engineering specification limits are 1.80 inches and 3.05 inches. What is the Cp (measure of potential capability)
Answers
Answer:
The correct answer is 4.167
Step-by-step explanation:
According to the given scenario, the calculation of the Cp i.e. measure of potential capability is as follows;
= (USL - LSL) ÷ 6 × standard deviation
= (3.05 inches - 1.80 inches) ÷ 6 × 0.05
= 1.25 ÷ 0.3
= 4.167
hence, the calculation of the Cp i.e. measure of potential capability is 4.167

Suppose lines EF and GH are reflected over the line y = x to form the lines JK and LM. Which statement would be true about the lines?
A.
Line JK and line LM will be parallel.
B.
Line JK and line LM will be perpendicular.
C.
The slope of line JK will be the same as the slope of line EF.
D.
The slope of line LM will be the negative reciprocal of the slope of line GH.
Answers
Answer:
A.
Step-by-step explanation:
I believe the answer is A. (Line JK and line LM will be parallel) because lines EF and GH are parallel. Therefore if the are just reflected, the new set of lines will also be parallel.
EF: (-9,1) (-4,9)
[tex]\frac{1-9}{-9+4}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6
GH: (-5,-2) (0,6)
[tex]\frac{-2 - 6}{-5-0}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6

5. Find JK to the nearest whole number.
A
Answers
Answer:
JK ≈ 63 units
Step-by-step explanation:
Using the sine ratio in the right triangle
sin44° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{90}[/tex] ( multiply both sides by 90 )
90 × sin44° = JK , that is
JK ≈ 63 ( to the nearest whole number )
Answer:
Sin(x) = Opposite ÷ Hypotenuse
Sin(44) = JK ÷ 90
0.6946583705 = JK ÷ 90
0.6946583705 × 90 = JK
JK = 62.5192533413
Rounding JK to the nearest whole number:
JK = 63

where RS = 6y + 2, ST = 2y + 7, and RT = 13y - 21.
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete but a possibility is that the given parameters are points on a straight line.
I'll answer base on that assumption.
[tex]RS = 6y + 2[/tex]
[tex]ST =2y + 7[/tex]
[tex]RT =13y -21[/tex]
To solve for y, we have that:
[tex]RT = RS + ST[/tex]
This gives:
[tex]13y - 21 = 6y + 2 + 2y + 7[/tex]
Collect Like Terms
[tex]13y - 6y - 2y = 21 +2+7[/tex]
[tex]5y = 30[/tex]
Divide both sides by 5
[tex]y = 6[/tex]
To get the measure of each line. Substitute 6 for y in
[tex]RS = 6y + 2[/tex]
[tex]ST =2y + 7[/tex]
[tex]RT =13y -21[/tex]
[tex]RS = 6 * 6 + 2 = 36 + 2 = 38[/tex]
[tex]ST = 2*6 + 7 = 12 +7 = 19[/tex]
[tex]RT = 13*6 - 21 = 78 - 21 = 57[/tex]
Joshua drove his car a distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answers
Answer:
6 liters of gasoline
Step-by-step explanation:
Since, 1 km = 0.6214 miles
Therefore, 100 km = 0.6214 × 100 = 62.14 miles
∵ For 431.8 miles of driving Joshua required amount of gasoline = 10.4 gallons
∴ For 1 mile of driving gasoline required = [tex]\frac{10.4}{431.8}[/tex] gallons
∴ Gasoline required to drive 62.14 miles = [tex]\frac{10.4}{431.8}\times 62.14[/tex] gallons
= 1.4967
≈ 1.5 gallons
∵ 1 gallon of gasoline = 3.8 liters
∴ 1.5 gallons of gasoline = 3.8×1.5
= 5.7
≈ 6 liters
The number of liters of fuel should be 6 liters.
Calculation of number of liters:Since distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol).
So,
Since, 1 km = 0.6214 miles
Now
100 km = 0.6214 × 100 = 62.14 miles
The number of liters should be
[tex]= 10.4 \div 431.8 \times 62.14 \times 3.8[/tex]
= 6 liters

The only decimal that contains a digit that represents ten times the value of the digit to its' right is; 33.458
How to Interpret Decimals?From the question, we want to find the digit that represents ten times the value of the digit to its' right.
Now, when it comes to decimals, there is the whole number part which is the left side of the decimal while there is a fraction part which is the right side of the decimal.
Now, the decimal values given are;
36.295
33.458
37.889
Let us analyze each of them;
1) 36.295 = 30 + 6 + 2/10 + 9/100 + 5/1000
We can see that there is no number that is ten times the number to it's immediate right.
2) 33.458 = 30 + 3 + 4/10 + 5/100 + 8/1000
We can see that 30 is ten times the number to it's immediate right which is 3.
3) 37.889 = 30 + 7 + 8/10 + 8/100 + 9/1000
We can see that there is no number that is ten times the number to it's immediate right.
