Answer:

2204.4

Step-by-step explanation:

Okay so we want to always use order of operations: PEMDAS

Sop first we do what is in the parenthesis. 19*92 is 1748.

Now, going from left to right, we do multiplication and division. 76*32 is 2432. Then we divide that by 5 to get 486.4. And the last bit is 15*2 which is 30.

Your equation now is 486.4+1748-30.

The final answer is 2204.4

Answer:

2204.04

Step-by-step explanation:

Follow PEMDAS:

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

----------------------------------------------------------------------------

Since 19 and 92 are in parenthesis, we do those two first.

(19*92)

1,748

76 * 32 / 5 + 1,748 - 15 * 2

Next is multiply.

76 * 32

2,432

2,432 / 5 + 1,748 - 15 * 2

-15 * 2

-30

2,432 / 5 + 1,748 - 30

Now is dividing.

2,432 / 5

486.4

486.4 + 1,748 - 30

Now you add and subtract (left to right).

486.4 + 1,748

2234.4

2234.4 - 30

2204.4

Kaylis [27]

Answer:

f(1/3) = 9

Step-by-step explanation:

f(x)=1/x+2/x

Combine terms

f(x) = 3/x

f(1/3) = 3 / (1/3)

f(1/3) = 9

Please help i think the answer is c but im not sure
katrin2010 [14]

Answer:

It's C

Step-by-step explanation:

Because the angle measurements are the same on rectangles and they have the same side lengths but the one on the right is a smaller rectangle which its only half the side of the bigger one.

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto
ruslelena [56]
X(u, v) = (2(v - c) / (d - c) + 1)cos(pi * (u - a) / (2b - 2a))
y(u, v) = (2(v - c) / (d - c) + 1)sin(pi * (u - a) / (2b - 2a))

As v ranges from c to d, 2(v - c) / (d - c) + 1 will range from 1 to 3, which is the perfect range for the radius. As u ranges from a to b, pi * (u - a) / (2b - 2a) will range from 0 to pi/2, which is the perfect range for the angle. So, this maps the rectangle to R.

If b (middle term) is negative and c (last term is positive) then what do you know about the two factors? ex. 2x^2-7x+6
seraphim [82]

Answer:

  signs of the constants in the binomial factors are negative

Step-by-step explanation:

Assuming the first term (a) is positive, the fact that c is negative means the constants in the binomial factors have the same sign. The negative b means that sign is negative.

  2x^2 -7x +6 = (x -2)(2x -3)

__

<em>Further comment</em>

c is the product of the constants in the binomial factors so will be positive when both those constants have the same sign.

b is the sum of the constants in the binomial factors. If both factors have the same sign (c > 0), then those constants have the same sign as b.

In this analysis, "a" is assumed to be positive. If it is not, then the same analysis can be done after reversing all of the signs.
