Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 0)

m = $\frac{0-6}{6-0}$ = $\frac{-6}{6}$ = - 1

Note the line crosses the y- axis at (0, 6 ) ⇒ c = 6

y = - x + 6 or y = 6 - x ⇒ B

Find the 10th and nth term of each G.P.:5,25,125,.....

RUDIKE [14]

Answer:

The $n^{th}$ of the sequence

$t_{n} = ar^{n-1}$

The $10^{th}$ of the sequence

$t_{10} = 5(5)^{10-1} = 9,765,625$

Step-by-step explanation:

Explanation:-

Given that the geometric sequence

5, 25 , 125 ,....

First-term a= 5

Difference $r = \frac{25}{5} =5$

The $n^{th}$ of the sequence

$t_{n} = ar^{n-1}$

The $10^{th}$ of the sequence

$t_{10} = 5(5)^{10-1} = 9,765,625$

Jamie has a half-sheet cake. If she has six friends, how much will each one get?

sesenic [268]

Answer:

<h2>The answer is </h2><h2>B. 1/12</h2>

Step-by-step explanation:

step one:

From the problem state, we can actually conclude that Jamie wants to share the half sheet of cake among her 6 friends

step two:

we can express this problem mathematically as

$=\frac{1}{\frac{2}{6} }$

we can inverse the denominator and use a multiplication sign instead

$\\\\= \frac{1}{2}*\frac{1}{6}$

multiplying both denominators we have

$\\\\= \frac{1}{12}$

The answer is B 1/12

The number y of hits a new website receives each month can be modeled by y = 4070ekt, where t represents the number of months th

makvit [3.9K]

Answer:

k = 0.2645

Step-by-step explanation:

Given model:

y = 4070 $e^{kt}$

y = no. of hits website received = 9000 (in 3rd month)

t= no. of months website has been operational = 3

put in the above equation:

9000 = 4070 $e^{3k}$

$\frac{9000}{4070}$ = $e^{3k}$

$\frac{900}{407}$ = $e^{3k}$

Taking natural logarithm on both sides, we get:

$ln\frac{900}{407}$ = $ln(e^{3k})$

$ln\frac{900}{407}$ = 3k lne

lne=1

$ln \frac{900}{407}$ = 3k

or k = $\frac{1}{3}$ $ln\frac{900}{(407)}$

k = $\frac{1}{3}$ (0.7936)

k = 0.2645
