Answer:

<em>y</em> = $1 + $2<em>x</em>

Step-by-step explanation:

The one dollar represents the amount of the party alone. The two dollars multiplied by the x gets you how much money will be spent towards guests altogether. Adding these gets you the total cost. (FYI - I put the dollar sign, but you may not need it.)

Use Euler’s method with two steps to estimate y(1) if y(x) is the solution to dy dx = x + y, y(0) = 1. Write your answer in the
tresset_1 [31]

Answer:

1.5

Step-by-step explanation:

The Euler's method is a common approximation method for the solution of differential equations. It can be used to obtain an approximate value of a given function. The Euler's formula is:

y_{n} = y_{n-1} + hF(_{x_{n-1},y_{n-1}})

Therefore, n =1 will give:

y_{1} = y_{0} + hF(x_{0},y_{0})

h is the step size and it is equivalent to \frac{x_{1}-x_{2}}{2} = \frac{1-0}{2}=\frac{1}{2}

F(x_{0},y_{0}) = x_{0} + y_{0} = 0 + 1 = 1

y_{1} = 1 + (0.5)(0+1) = 1 + (0.5)(1) = 1 + 0.5 = 1.5

HELP ASAP <br><br> What is the value of x?<br> O x = 55°<br> O x = 60°<br> O x = 70°<br> O x = 110°
valina [46]

Answer:

the answer is the answer the answer is x=55 degrees because the angle sum for a triangle is 180 degrees and because we are told angle A and angle C are congruent that means you can simply take 180 - 70 to get 110 and i simply divided that by 2 and got 55 degrees

The measure of angle A is 4 degrees greater than the measure of angle B. The two angles are complementary. Find the measure for
Elenna [48]
Sorry but i only know the answer for the 1st question.
--------------------------
If the angles are complementary they measure 90°.
1st find half of 90
which is 45.
Find 4 more than 45.
which is 49°
then subtract 90-49=41
so the measurement of the 2 angles are
49 and 41
Hope it helps!!
