Answer:

$y+5.6 = -2.9 (x + 1.2)$

Step-by-step explanation:

Equation of straight line in point slope form is given as

$y -y_1 = m(x- x_1)$ -------------(1)

Here

$m =-2.9$ and $(x_1, y_1) = (-1.2, -5.6)$

Substituting values in equation (1)

$y+5.6 = -2.9 (x + 1.2)$

Ken went to the store for his mother. He spent $2.37 on groceries. In addition, his mother said he could spend $0.35 on candy. W

Sladkaya [172]

Ken spent $2.37 on groceries and $0.35 on candy, and paid for them with a 5 dollar bill.

To find how much money Ken spent, we add up how much he spent on groceries and candy

Total amount spent = 2.37+0.35= $2.72

Since he paid with a 5 dollar bill, we need to subtract it from how much he spent to find the change

Change = 5 - 2.72 = $2.28

Ken got $2.28 in change.

Use sigma notation to represent the sum of a geometric series with a first term of 3 and a common ratio of . A. B. C. D.

maksim [4K]

Answer:

$\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}]$

Step-by-step explanation:

A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

The first term is denoted by a and the common ratio is denoted by r.

A geometric sequence has the form:

a, ar, ar², ar³, . . .

The nth term of a geometric sequence is $ar^{n-1}$

Therefore the sum of the first n terms is:

$\Sigma_{k=1}^{n}(ar^{k-1})$

Given a geometric series with a first term of 3 and a common ratio of 10/9, the sum of the first n terms is:

$\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}]$

Which of the following is equivalent to f(x)?

Fynjy0 [20]

Answer:

D. $x^{-3/2}$

Step-by-step explanation:

<u>Given function:</u>

$f(x) = \frac{1}{x\sqrt{x} }$

<u>Equivalent expression is:</u>

$\frac{1}{x\sqrt{x} } = x^{-1}x^{-1/2} = x^{-1 - 1/2} = x^{-3/2}$

Correct choice is D
