Answer:
247.21
Step-by-step explanation:
equation for height : c= a2 + b2
4.82 + 9.32
≈10.46566
equation for surface area: A=5
/4tan(54°)a2+5a
/2h2+(atan(54°)
/2)2
5
/4·tan(54°)·72+5·7
/2·7.972+(7·tan(54°)
/2)2
≈247.21018
round to nearest hundredth: 247.21
Subtract the amount she has saved from the price of the laptop:
849 - 232 = 617
Now divide the amount she still needs by the amount she saves per week:
617 / 28 = 22.04
Because the answer has a number to the right of the decimal, she will need to save for 23 full weeks to have enough money.
If she saves for 22 weeks, she would be $1 short:
22 x 28 = 616 + 232 = 848
Answer in simplified expression: 5a+4
Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72
Hope this helped :)
The inverse function of f(x) is 
and the domain is x > 6
<h3>How to determine the inverse function?</h3>
The function is given as:
f(x) = x^2 + 6
Rewrite as:
y = x^2 + 6
Swap x and y
x = y^2 + 6
Subtract 6 from both sides
y^2 = x - 6
Take the square root
Rewrite as:
Hence, the inverse function of f(x) is and the domain is x > 6
