Answer:

65 and 25

Step-by-step explanation:

90=(5x+10)+(6x-41)

121=11x

11=x

Going back to the angles:

5(11)+10

=55+10

=65 this is the first angle

6(11)-41

=66-41

25 this is the second angle

some kids like to ride their bikes to and from school let d be the distance in miles from a kid home to school write 2 expressio
Nesterboy [21]
Expression 1;  If your friend bikes 1.5 miles home from school each day for 4 weeks, they bike a total of - miles in that time period. The math I did was multiply 5 by 4 to get 20 school days in 4 weeks, and multiplied 1.5 by 20 to get 30 miles biked in 4 weeks.
Expression 2;  If you bike 3.25 miles home from school each day, using the same math shown in the previous expression, substituting 1.5 for 3.25. Using that math, you would bike 65 miles in 4 weeks.

Sarcastic conclusion;  You and your friend both get quite the leg day just to get home from school!

Question 3
wariber [46]

Answer:

Incorrect

The correct answer is 1/6

Step-by-step explanation:

Freddy is incorrect. You are not supposed to subract the denominators. When you are solving the equation you have to find a common denominator. You can only subtract the numerator, and the denominator is the same.

Find the LCM. The LCM in this case is 6.

\frac{3}{6} -\frac{2}{6}

Remember, only subtract the numerators. The denominator will still be 6.

\frac{1}{6}

1/6 is the correct answer. I hope this helps you!

The formula κ​(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a​ twice-differentiable plane curve as a function of x. Use thi
Katyanochek1 [597]

Answer:

K(x) =  \frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }    ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = -5x^2

first Determine the value of F'(x)

F'(x) = \frac{d(-5x^2)}{dy}

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = \frac{d(-10x)}{dy}

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x)  = \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }

 K(x) =  \frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }    ( curvature function)
