Can someone tell me how do I solve this. how is the result 2.40

liubo4ka [24]

Step-by-step explanation:

<u>Properties used</u>

logₐ a = 1
log aᵇ = b log a
log ab = log a + log b

See the steps below

- log (4*10⁻³) =
- (log 4 + log 10⁻³) = (log 4 ≈ 0.6 rounded)
- (0.6 - 3*log 10) =
- (0.6 - 3*1) =
- (0.6 - 3) =
- (- 2.4) =
2.4

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hu

notsponge [240]

The monthly cost for 17 hundred of cubic feet is $52.13.

<h3>What is a linear equation?</h3>

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the bill paid for x HCF of water.

The slope is 1.45, hence m = 1.45.

The monthly cost for 13 HCF is $46.33, hence:

46.33 = 1.45(13) + b

b = 27.48

y = 1.45x + 27.48

For 17 HCF:

y = 1.45(17) + 27.48 = 52.13

The monthly cost for 17 hundred of cubic feet is $52.13.

List possible rational zeroes of the function. 3x^5-8x^4+6x^2+7x-12.

spayn [35]

First list all the positive and negative factors of the constant term in the expression: ±(1,2,3,4,6,12) these will be the values for "p"

Second list all the positive and negative factors of the leading coefficient:
±(1,3) these will be the values for "q"

Now list all the possible values of $\frac{p}{q}$ these will be the possible rational zeros of the polynomial function:
±( $\frac{1}{1} , \frac{1}{3} , \frac{2}{1} , \frac{2}{3} , \frac{3}{1} , \frac{3}{3}, \frac{4}{1} , \frac{4}{3} , \frac{6}{1} , \frac{6}{3} , \frac{12}{1} , \frac{12}{3}$ )

these can be reduced to the following list:
±(1, $\frac{1}{3}$ , 2, $\frac{2}{3}$ , 3, 4, $\frac{4}{3}$ , 6, 12

This list represents the possible rational zeros of the function. You can then use synthetic division to narrow down the actual roots of the function.
