Answer:

[tex]y=\sin \left(x\right)x^2+c_1x^2[/tex]

Step-by-step explanation:

Substitute dy/dx with y

[tex]y'\:-\left(\frac{2}{x}\right)y=x^2\cos \left(x\right)[/tex]

Step-by-step explanation:

66-95-99.7 rule

standard deviation is 10. meaning that it'll deviate twice meaning you use the 95%

95% of 200 is 190, so 190 students had scores between 40 and 80

Answer:

I think that the answer is

-g + 12

I used a math check calculator and it said that the above is the answer

Answer:

(1) 56 miles/hour

Step-by-step explanation:

We need to find the average rate of change from t = 2 to t = 9.

At t = 2 hours, d = 106 miles.

At t = 9 hours, d = 498 miles.

The average rate of change in function f(x) from x = a to x = b is

[f(b) - f(a)]/(b - a)

average rate of change from t = 2 to t = 9 =

(498 - 106)/(9 - 2) = 392/7 = 56

Answer: (1) 56 miles/hour

Answer:

Linear function: y = 24x + 25

Step-by-step explanation:

24 hours = 1 day

30 days = 1 month

0.15 x 24 = 6

30 x 6 = 180

180 + 25 = 205

Linear function: y = 24x + 25

Hope this helps! :)

Answer:

There are two, the first one is 4 and the second is 132

Step-by-step explanation:

36 divided by 3 is 12, so 48 divided by 12 would give us the answer 4. In the last one, you multiply 11 by 12 instead.

Step-by-step explanation:

the second one is 132 uuwwuu

Answer:

Coordinates of point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

Step-by-step explanation:

Given the point C

A dilation with a scale factor of 5 means the size of the coordinates of the image of point P will be 5 times larger than than the original coordinates of point C.

Thus, the rule of dilation by a scale factor 5 is:

(x, y)  →  (5x, 5y)

C(2, 1)  →  (5x, 5y) = (5(2), 5(1)) = C'(10, 5)

Therefore, coordinates of the point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

Answer:

.

Step-by-step explanation:

Answer: Yes

Step-by-step explanation: We're going to have to substitute

in the coordinates of that ordered pair into the equation.

I am going to substitute in the x and substitute in the y.

So it's really 5(2) + 3(-3) = 1.

From here it should be pretty straightforward,

all we are doing is evaluating the statement.

Simplifying on the left we have 10 + -9 = 1 or 1 = 1.

Now we know that the ordered pair (2, -3) satisfies this equation.

Answer:

288

Step-by-step explanation:

Evaluate Using the Given Value

2 (a (2b + 3c)) for a = 8 , b = 3 , and c = 4

Replace the variable a with 8 in the e xpression.

2 ((8) (2b + 3c))

Replace the variable b with 3 in the expression.

2 ((8) (2 (3) + 3c))

Replace the variable c with 4 in the expression.

2 ((8) (2 (3) + 3 (4)))

Simplify each term.

Multiply 2 by 3.

2 (8 (6 + 3 (4)))

 Multiply 3 by 4.

2 (8 (6 + 12))

Simplify the expression. Tap for fewer steps...

Add 6 and 12.

2 (8 ⋅ 18)

 Multiply 8 by 18.

2 ⋅ 144

 Multiply 2 by 144.

Answer: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer: PLEASE READ: The coefficients of (x + y)n are given by the nth row of Pascal's triangle. To generate Pascal's triangle, add adjacent terms on a row to determine the term directly below them. Each row is a "palindrome"- that is, it is the same if read from left to right or from right to left.
