Answer 1

Answer: #2:

Square root of 135 is approximately 11.61895, so it's closest to 11 and 12.

#3:

Square root of 200 is approximately 14.1421356, so it's closest to 14 and 15.

#4:

Square root of 192 is approximately 13.8564065, so it's closest to 13 and 14.

#5:

Square root of 37 is approximately 6.08276253, so it's closest to 6 and 7.

Answer 2

Answer: √135 = 11,61895003862225, so two whole numbers closest to that are 11and 12

√200 = 14,14213562373095, so two whole numbers closest to that are 14 and 15

√192 = 13,85640646055102, so two whole numbers closest to that are 13 and 14

√37 = 6,08276253029822, so two whole numbers closest to that are 6 and 7

Simplifying 14x + -21xy

Factor out the Greatest Common Factor (GCF), '7x'. 7x(2 + -3y)

Final result:
7x(2 + -3y)

that is the answer on how to do it

You need to find the common number/letter in order to factorise and it should be like this:

Please help!!!!!!!!!!If f(x) varies directly with x2 and f(x)=10 when x=−4 , what is the value of f(x) when x = 3?
−14.4

−5.625

5.625

14.4

Answers

Answer:

Step-by-step explanation:

First thing, let's call f(x) "y". So y varies directly with x^2 looks like this:

y = kx^2

k is our constant of variation. We need to solve for k before we can find what we are asked to find.

Filling in:

10 = k(-4)^2 and

10 = 16 k so

k = 5/8 (reduced)

Now we will use that value of k along with the given of x = 3 to find y:

y = (5/8)(3)^2 and

y = (5/8)(9)

y = 45/8 which simplifies to

y = 5.625

Final answer:

The function f(x) varies directly with x2. First, find the constant of variation, then use this constant to find the value of the function at the desired x value. The value of f(x) when x = 3 is 5.625.

Explanation:

The phrase 'f(x) varies directly with x2' implies that there is a linear relationship between f(x) and x2. That is to say, the formula will be something like f(x) = kx2 where k is the constant of variation. We can solve for k using the given condition f(x) = 10 when x = -4. By substituting these values into the equation, we get 10 = k(-4)2, which simplifies to 10 = 16k. Solving for k, we find k = 10 / 16 = 0.625.

To find the value of f(x) when x = 3, we substitute x = 3 into the formula f(x) = 0.625x2, which results in f(3) = 0.625 * 9 = 5.625.
