Use the graph below to determine a1 and d for the sequence.

1 answer:

4 0

A1 would be the first y value, which is 3 and d is the ratio ( distance between each y value) which is 3 ( add 3 to the y value to get the next one)

The answer is a1= 2, d = 3

Answer:

The answer to number 3 would be 6 on the number line, open circle, and then a line dashed to 42, and 4 on the number line, closed circle, and a closed line to 7.

The answer to number 4 would be -8 on the number line, open circle, and then a line dashed to 2, and 9, open circle closed line to 81.

If f(x) = startfraction 7 over x endfraction, then what is the slope of f(x) at x = 5? round your answer to 3 decimal places.

Flura [38]

The slope of the function to 3 dp is 0.280

<h3>Slope of a function</h3>

Slope is also known as the gradient of a function

Given the function $f(x) =\frac{7}{x}$

Taking the derivative of the function will give:

$f'(x)=-\frac{7}{x^2}$

Substitute x = 5 into the equation to have:

$f'(x)=-\frac{7}{5^2}$

$f'(x) = -\frac{7}{25}$

Hence the slope of the function to 3 dp is 0.280

Solve 5y'' + 3y' – 2y = 0, y(0) = 0, y'(O) = 2.8 y(t) =( Preview

Karolina [17]

Answer:

$y=\frac{4}{5}e^{t}-\frac{4}{5}e^{-\frac{2}{5}t}$

Step-by-step explanation:

The given equation 5y'' + 3y' - 2y =0 can be written as

$(5D^{2}+3D-2)y(t)=0$

Solving for complementary function we have Roots of $(5D^{2}+3D-2)$ as follows

$(5D^{2}+5D-2D-2)$

$5D(D+1)-2(D+1)=0\\\\(5D-2)(D+1)=0\\\\\therefore D=-1\\D=+2/5$

Thus the complementary function becomes

y= $y=c_{1}e^{m_{1}t}+c_{2}e^{m_{2}t}$

where

$m_{1},m_{2}$ are calculated roots

thus solution becomes

$y=c_{1}e^{-t}+c_{2}e^{\frac{2}{5}t}$

Now to solve for the coefficients we use the given boundary conditions

$y(0)=0\\\\\therefore c_{1}+c_{2}=0\\\\y'(0)=-c_{1}+\frac{2}{5}c_{2}=2.8\\\\\therefore c_{2}+\frac{2}{5}c_{2}=2.8\\\\c_{2}=2\\\\\therefore c_{1}=-2}$

hence the solution becomes

$y=-2e^-{t}+2e^{\frac{2}{5}t}$

Nina is 10 years younger than Deepak. Deepak is 3 times as old as Nina. Which system of equations can be used to find d, Deepak'

kifflom [539]

The answer is A. Deepak is 10 years older than Nina, so it cancels out B and D. And Deepak is 3 times Nina's age, not the other way around.
