What is the combined length of all the buttons longer than 1 inch?
Leya [2.2K]
Combined means to add so you are going to add anything over 1 because it says longer than 1

1 1/4  has 2 marks so you add 1 1/4 + 1 1/4 = 
they have like denominators so you can add them together

1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2 

so your answer is 2 1/2

Consider the differential equation y'' − y' − 30y = 0. Verify that the functions e−5x and e6x form a fundamental set of solution
Alex Ar [27]

Answer:

Step-by-step explanation:

We have to take the derivatives for both functions and replace in the differential equation. Hence

for y=e^{-5x}:

y(x)=e^{-5x}\\y'(x)=-5e^{-5x}\\y''(x)=25e^{-5x}\\

for y=e^{6x}:

y(x)=e^{6x}\\y'(x)=6e^{6x}\\y''(x)=36e^{6x}\\

Now we replace in the differential equation  y'' − y' − 30y = 0

for y=e^{-5x}:

25e^{-5x}+5e^{-5x}-30e^{-5x}=0\\25+5-30=0

for y=e^{6x}:

36e^{6x}-6e^{6x}-30=0\\36-6+30=0

Now, to know if both function are linearly independent we calculate the Wronskian

W(f,g)=fg'-f'g

W(e^{-5x},e^{6x})=(e^{-5x})(6e^{6x})-(-5e^{-5x})(e^{6x})\neq 0

I hope this is useful for you

Best regard

Find the area of the polygon.<br> A) 96 cm2 <br> B) 192 cm2 <br> C) 208 cm2 <br> D) 224 cm2
chubhunter [2.5K]

Answer:

208 cm2 (C)

Step-by-step explanation:

16*6=96

The area of the LEFT polygon is 96 according to length times width.

Since the entire length is 14 and the rectangle alone has a length of 6, 14-6=8 which then you multiply by 14 to get your area of the RIGHT polygon.

8*14= 112

When you add both area values together you get the area of the entire polygon.

96+112=208
