Answer:
The value of h'(7) = 44 .
Step-by-step explanation:
Given:
f'(7)=9 and g(7)= 5
We have to find : h'(7)
Also,
⇔ 
...equation (i)
Plugging the value of 'x' = 7 in equation (i) the equation can be re-framed as:
⇔ 
⇔
Now plugging the value of f'=(7)=9 and g(7)=5 in the above equation:
⇔ 
⇔ 
⇔ 
So the value of h=(7) = 44 .
You would use Pythagorean theorem to help u out if u have 2 sides u should be able to do it.
Let
A (-4,35)
B (-3,20)
C (-2,10)
D (-1,5)
E (0,8)
F (1,10)
G (2,15)
H (3,30)
I (4,48)
using a graph tool
case a) y=2.23x²+1.62x+5.26
see the attached figure N 1
case b) y=4.63x²+0.84x+4.14
see the attached figure N 2
case c) y=0.98x²+3.06x+6.02
see the attached figure N 3
case d) y=3.72x²+2.94x+3.21

therefore
the answer iscase a) y=2.23x²+1.62x+5.26
B is the right answer because you can set up a ratio like this:
If you solve for A, then you get:
Hopefully this makes sense. Also, in the textbox,
∠A = 45°
and your answer's B.
Answer:
A store pays $10 for a bracelet and the markup is 115% of customer
markup percentage is 115% = 1.15
markup amount = cost price * markup percentage
= 10 * 1.15 = 11.5
price with markup price = 10 + 11.5 = 21.5
Now we apply sales tax for the price
sales tax of 5.5 % = 0.055
Tax amount = price with markup * tax percentage
= 21.5 * 0.055= 1.1825
the total cost of the bracelet = Price + tax amount
=21.5 + 1.1825 = 22.6825
$22.68 is the total cost of the bracelet
