Answer:

√97

Step-by-step explanation:
The formula is: d=√(x²-x¹)²+(y²-y¹)²

√(-9 - -5)^2 + (9 - 0)^2
√(-4)2 + (9)2
√97
It cannot be simplified any further.

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 $\frac{x_{1}-x_{2}}{2} = \frac{1-0}{2}=\frac{1}{2}$

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

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

An outside thermometer reads -5 degrees at 8:00 a.m. By 12:30 p.m. the temperature outside has increased by 11 degrees. At 12:30

Lesechka [4]

Answer:

73 degrees.

Step-by-step explanation:

So, let's see the information provided in the question.

At 8 AM, the thermometer was reading -5 degrees.

At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.

Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.

So, we know the outside temperature at 12:30 PM is +6 degrees.

11 times 6 = 66 degrees.

Then we add the additional 7 degrees, to get a total of 73 degrees.

seropon [69]

Answer:

-2a^4+8a^3-6a^2

Step-by-step explanation:

2a^2(a-1)(3-a)

2a^2(-a^2 +3a-3+a)

2a^2(-a^2+4a-3)

-2a^4+8a^3-6a^2

Bumek [7]

Answer:

28.125

Step-by-step explanation:

A bar weights 3 ounces, she has a box of 150 so you multiply

150 times 3 = 450

well one pound equals 16 ounces, so you divide

450 divide by 16 = 28.125
