Answer:

i think it is the second one

Step-by-step explanation:

Exhaust all normal steps of factoring before deciding that you have a prime polynomial on your hands. Look for two numbers whose product is 8 and sum is 2. Check for the 2 and 4 when both are either plus or both are minus, for 8.

The height of the water in an above ground pool is 3

Firdavs [7]

It will take 6 minutes to drain the pool.

<h2>Explanation:</h2>

As the problem states the height of the water in an above ground pool is 3ft. In other word:

3 ft is our starting point.

The pool needs to be drained at a Rate of Change of 1/2 inches per minutes. In other words:

The rate of change is constant, so we'll have a line with slope -1/2.

Therefore, we can write an equation as:

$h=3-\frac{1}{2}t \\ \\ \\ h:Height \\ \\ t:time \\ \\ \\ The \ slope \ is \ negative \ because \ the \ pool \ needs \ to \ be \ drained$

To drain the pool implies that we don't have any water in the pool, in other words this is true if and only if:

$h=0$

So:

$h=3-\frac{1}{2}t \\ \\0=3-\frac{1}{2}t \\ \\ \\ Solving \ for \ t: \\ \\ \frac{1}{2}t=3 \\ \\ t=6$

So, it will take 6 minutes to drain the pool.

What is the value of x that will make each of the two ratios proportional?

PilotLPTM [1.2K]

Answer:

a=7, b=14

Step-by-step explanation:

a. 2/6=x/21

cross multiply=

2×21=x×6

then solve

42=6x

divide both sides by 6

x=42/6=7

b. 150/84=25/x

cross multiply=

84×25=150×x

then solve

2100=150x

divide both sides by 150

x=2100/150=14

What can you say about the end behavior of the function f(x)=-4x^6+6x^2-52

shepuryov [24]

Answer:

As x gets smaller, pointing to negative infinity, the value of f decreses, pointing to negative infinity.

As x gets increases, pointing to positve infinity, the value of f decreses, pointing to negative infinity.

Step-by-step explanation:

To find the end behaviour of a function f(x), we calculate these following limits:

$\lim_{x \to +\infty} f(x)$

And

$\lim_{x \to -\infty} f(x)$

In this question:

$f(x) = -4x^{6} + 6x^{2} - 52$

At negative infinity:

$\lim_{x \to -\infty} f(x) = \lim_{x \to -\infty} -4x^{6} + 6x^{2} - 52$

When the variable points to infinity, we only consider the term with the highest exponent. So

$\lim_{x \to -\infty} -4x^{6} + 6x^{2} - 52 = \lim_{x \to -\infty} -4x^{6} = -4*(-\infty)^{6} = -(\infty) = -\infty$

So as x gets smaller, pointing to negative infinity, the value of f decreses, pointing to negative infinity.

Positive infinity:

$\lim_{x \to \infty} f(x) = \lim_{x \to \infty} -4x^{6} + 6x^{2} - 52 = \lim_{x \to \infty} -4x^{6} = -4*(\infty)^{6} = -(\infty) = -\infty$

So as x gets increases, pointing to positve infinity, the value of f decreses, pointing to negative infinity.

Write 3^-4 as a fraction

Ad libitum [116K]

Answer: 1/3^4 or 1 over 3 fourths beacuse you need to just flip it to get the exponent to be positive. 3^-4 is basically 3^-4 over 1.

How do you solve 5x + 7 = 2x + 1

quester [9]

Answer:

x = -2

Step-by-step explanation:

5x + 7 = 2x + 1

subtract both sides by 2x

3x + 7 = 1

subtract both side by 7

3x = -6

divide both sides by 3

x = -2
