Hi. I need help with these questions (see image)
Please show workings.
Answer:
see explanation
Step-by-step explanation:
Using the chain rule
Given
y = f(g(x)), then
[tex]\frac{dy}{dx}[/tex] = f'(g(x)) × g'(x) ← chain rule
and the standard derivatives
[tex]\frac{d}{dx}[/tex] ([tex]log_{a}[/tex] x ) = [tex]\frac{1}{xlna}[/tex] , [tex]\frac{d}{dx}[/tex](lnx) = [tex]\frac{1}{x}[/tex]
(a)
Given
y = [tex]log_{a}[/tex][tex]\sqrt{(1+x)}[/tex]
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{d}{dx}[/tex] ([tex](1+x)^{\frac{1}{2} }[/tex]
= [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{1}{2}[/tex] [tex](1+x)^{-\frac{1}{2} }[/tex] × [tex]\frac{d}{dx}[/tex] (1 + x)
= [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{1}{2\sqrt{(1+x)} }[/tex] × 1
= [tex]\frac{1}{2lna(1+x)}[/tex]
= [tex]\frac{1}{(1+x)lna^2}[/tex]
(b)
Given
y = ln sinx
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{sinx}[/tex] × [tex]\frac{d}{dx}[/tex](sinx)
= [tex]\frac{1}{sinx}[/tex] × cosx
= [tex]\frac{cosx}{sinx}[/tex]
= cotx
Rewrite the problem using fewer words. Leave out information that you do not need to solve the problem. Then solve the problem. For a science project, you record the high temperature each day. The high temperature on Day 1 was 6°less than on Day 4 and 4°less than on Day 10. The high temperature on Day 10 was 62°F. What was the high temperature on Day 1?
Answer:
Each day, you record the high temperature* (you don't necessarily need to say that it is for a science project). On Day 1, it was 4* less than Day 10**. It hit 62* F on Day 10. What was the high temperature on Day 1?
Because we know that on Day 1, the temperature was 4* less than on Day 10, and the high temperature on Day 10 was 62*, the high temperature on Day 1 was therefore 58*. Because 62 - 4 = 58.
Step-by-step explanation:
*You don't necessarily need to say that it was for a science project.
**The information for Day 4 is irrelevant too because we are not given the temperature for Day 4, therefore it does not help us find the answer.

1 1/2-2/6= 1 1/6
Step-by-step explanation:
1. 4/5 × 3 = 12/15
2/3 × 5 = 10/15
12/15 + 10/15 = 22/15= 1 7/15

Jack wants to know how much water a sphere can hold with a radius of 8 cm. Find the volume. Use 3.14
for pi.
a
2144.7 cm
b
254 cm
С
83.6 cm
d
2220 cm
Answer:
a
Step-by-step explanation:
Volume of water in sphere is 2,143.57 cm³
Given that;Radius of sphere = 8 cm
Value of π = 3.14
Find:Volume of water in sphere
Computation:Volume of sphere = (4/3)πr³
Volume of water in sphere = (4/3)(3.14)(8)³
Volume of water in sphere = (4/3)(3.14)(512)
Volume of water in sphere = 2,143.57 cm³
So, Option "A" is the correct answer to the following question.

A $280 suit is marked down by 30%. Find the sale price.
The sale price is $
The sale price of suit will be $196.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
A $280 suit is marked down by 30%.
Now,
Since, A $280 suit is marked down by 30%.
Hence, The sale price = $280 - 30% of 280
= $280 - 30/100 × 280
= $280 - $84
= $196
Thus, The sale price of suit = $196.

In Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day. At that rate, how much
would a $14 wool blanket cost five days later?
Hint: Use the following equation to calculate future price: Future price = (current price) * (inflation rate)^t where t the number of days
in the future.
Instructions: Round your response to one decimal place.
_million?
Five days later the wool blanket would cost $ 1,400,000.
Given that in Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day, to determine, at that rate, how much would a $ 14 wool blanket cost five days later, the following calculation must be performed:
Future price = (current price) * (inflation rate) ^ number of days
X = 14 x 10 ^ 5
X = 14 x 100,000
X = 1,400,000
Therefore, five days later the wool blanket would cost $ 1,400,000.
