The length of a rectangle with area 38 in2 depends on its width. Write the formula that describes the length of the rectangle as
Ostrovityanka [42]

Answer:

L = 38/W

Step-by-step explanation:

The area of a rectangle is computed by multiplying length by width. For length L and width W in inches, your rectangle has area ...

A = LW

38 = LW

Then the length can be found by dividing the equation by W:

L = 38/W

What is the solution of 4|x – 9| + 6 > 42?
OlgaM077 [116]

Answer:

Choice B is correct answer.

Step-by-step explanation:

We have given an inequality.

4|x – 9| + 6 > 42

We have to find the solution of given inequality.

Adding -6 to both sides of above inequality, we have

4|x – 9| + 6 -6 > 42-6

4|x – 9| + 0 > 36

4|x – 9|  > 36

Dividing above inequality by 4 , we have

4|x – 9|  > 36

(4|x – 9|) / 4  > 36 / 4

|x – 9|  > 9

Applying absolute value property, we have

-9 > x-9 > 9

Adding 9 to both sides of above equation, we have

-9+9 > x-9+9 > 9+9

0 > x > 18

Hence, we can write above inequality as:

x < 0 or x > 18 which is the answer.

If m ≤ f(x) ≤ M for a ≤ x ≤ b, where m is the absolute minimum and M is the absolute maximum of f on the interval [a, b], then
agasfer [191]

Answer:

smaller value is 1.2

larger value is 6

Step-by-step explanation:

f(x)=\frac{3}{1+x^{2} }

when x=a=0, one has

f(0)=\frac{3}{1+0^{2} } \\f(0)=3

now, when x=b=2, one has

f(2)=\frac{3}{1+2^{2} } \\f(2)=\frac{3}{5}

Therefore, the absolute minumun is

m=\frac{3}{5}

and the absolute maximun is

M=3

The approximation to the integral is

\frac{3}{5}(2-0)\leq \int\limits^2_0 {f(x)} \, dx  \leq 3(2-0)

hence

\frac{3}{5}(2)\leq \int\limits^2_0 {f(x)} \, dx  \leq 3(2)\\\frac{6}{5} \leq \int\limits^2_0 {f(x)} \, dx  \leq 6\\1.2 \leq \int\limits^2_0 {f(x)} \, dx  \leq 6

A value to describe the steepness of a strainght line
marta [7]
That depends if the line is vertical or horizontal. If the line is vertical, the slope (steepness) of the line is undefined (this is because the x values across the entire line are the same). If the line is horizontal, the slope of the line is 0 (this is because the y values will always subtract to equal 0 when you use the form y1 - y2/x1 - x2 to find slope).

Hope this helps.

Ivenika [448]

Answer:

Your answer is 15

Step-by-step explanation:

1) 6 + 4 = 10

2) -4 + -1 = -5

3) now add

4) 10 + -5 + 15

5) it's 15 because the bigger is positive.
