(7)-0, at the points x 71, 72, 73, 74, and 7.5 use euler's method with step size 0.1 to approximate the solution to the initial value pro oblemy - 2x+y the approximate solution to y'=2x-y? .y(7)=0, at the point x = 71 is (round to five decimal places as needed.)

2.68

Step-by-step explanation:

We are given that

h=0.1

y'=2x-y

y(7)=0,f(x,y)=2x-y

We have to find the approximate solution to the initial problem at x=7.1

Substitute the value then, we get

Substitute the values then, we get

Hence, the approximation solution to the initial problem at x=7.1 is =2.68

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
