What is the value of log625^5? A: -4 B:-1/4 C:1/4 D:4

shtirl [24]

Answer:

The value of $log_{625}(5)$ is $\frac{1}{4}$

Step-by-step explanation:

We want to evaluate $log_{625}(5)$ .

The base of this logarithm is $625$ and the number is $5$ .

We need to express the number $5$ as the base $625$ raised to a certain index.

This implies that, $log_{625}(5)=log_{625}(625^{\frac{1}{4}})$

Recall now that,

$log_a(m^n)=nlog_a(m)$ .

We apply this property to obtain,

$log_{625}(5)=\frac{1}{4}log_{625}(625)$

Recall again that,

$log_a(a)=1,a\ne0\:or\:1$ .This implies that,

$log_{625}(5)=\frac{1}{4}(1)$

$log_{625}(5)=\frac{1}{4}$

The correct answer is C.

The points , (−15,1) and , (−7,r) lie on a line with slope 5/4. Find the missing coordinate r. Click image to enlarge

Nadya [2.5K]

The missing coordinate r is 11.

Solution:

Given points are (–15, 1) and (–7, r).

$x_{1}=-15, x_{2}=-7, y_{1}=1 \text { and } y_{2}=7$

Slope (m) = $\frac{5}{4}$

<u>To find the missing coordinate r:</u>

Slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute the given values in the formula.

$$\frac{5}{4}=\frac{r-1}{-7-(-15)}$

$$\frac{5}{4}=\frac{r-1}{-7+15}$

$$\frac{5}{4}=\frac{r-1}{8}$

Do cross multiplication.

$8 \times 5=4(r-1)$

40 = 4r – 4

Add 4 on both side of the equation.

44 = 4r

Divide by 4 on both side of the equation.

11 = r

⇒ r = 11

Hence the missing coordinate r is 11.

How much money does a newspaper delivery person get per year?

Vadim26 [7]

That depends on numerous factors, including how many papers must be delivered every day, and how many days/weeks/months per year are involved. Strictly as a guess: you'd probably earn between $8 and $16 per hour. If you were to deliver papers for 2 hours each day, that'd come to $112-$224 per 7-day week. And so on. Ask for specifics applying to your city / delivery area.
