Answer:
b = 0.35 ; c = 2.03
Step-by-step explanation:
tan = opposite/hypotenuse
Therefore, tan (10) = b/2
b = 2 tan (10) = about 0.35
Use the Pythagorean theorem to find that c = 2.03
Solve for x.
c=8x+60
Flip the equation.
8x+60=c
Add -60 to both sides.
8x+60+−60=c+−60
8x=c−60
Divide both sides by 8.
8x/8=c−60/8
x=1/8c + −15/2
Answer: The answer is 9 because the equations represent the same expression but just in different forms.
Step-by-step explanation:
Answer:
y will increase by 8
Step-by-step explanation:
y = 8x+2
We increase x by 1
Replace x with x+1
y = 8(x+1) +2
y = 8x+8+2
y = 8x+2 +8
y will increase by 8
Answer:
(9 ^ 3) x 0.04 (4/99)
Step-by-step explanation:
This seems overwhelming, but after simplifying, it will look much easier
Numerator (First Row)
First, we will combine like terms and simplify the top row
(9 ^ <em>x</em> + 1) x 8 - (9 ^ <em>x</em> - 1) x 81
(9 ^ <em>x</em> + 1) - (9 ^ <em>x</em> - 1) x (8 x 81)
(9 ^ 2x) x 648
Denominator (Second Row)
Next, we can combine like terms and simplify the second row
(9 ^ <em>x</em>) x 66 - (9 ^ <em>x</em> - 2) x 243
(9 ^ <em>x</em>) - (9 ^ <em>x</em> - 2) x (66 x 243)
(9 ^ 2x + 2) x 16,038
Simplify
Our expression is now
(9 ^ 2x) x 648
(9 ^ 2x + 2) x 16,038
We can simplify it as
(9 ^ 3) x 0.04 (4/99)
