Answer:

Option 3rd is correct

Write the function in standard form.

Step-by-step explanation:

The standard form of the quadratic equation is given by:

y=Ax^2+Bx+C

As per the statement:

Given the function:

f(x) = 6x^2+5-42x

We have to find the first step writing f(x) vertex form.

Firstly, write the given function in standard form

by definition we have;

f(x) = 6x^2-42x+5

Therefore, the first step writing f(x) vertex form is, Write the function in standard form.

21. Carrie withdraws $10 from her account each day for 7 days.
Fiesta28 [93]

Answer:

a.70. b.50

Step-by-step explanation:

  • If Cartie takes $10 from her account for 7 days she would have taken $70 out.

7 \times 10 = 70

  • Next we look at the net problem it is asking us how much is left we already know from the equation above that we need to subtract 70 from 120
  • 70 - 120 = 50
  • We now have both answers A. being that she would have taken $70 in total out of her account and B. being that she would have $50 left in her account.

The formula for the nth term of an arithmetic sequence can be found using the formula a Subscript n Baseline = a Subscript 1 Bas
Gnoma [55]

The equation of nth term will be written as for n as will be (\rm a_n - a₁ + d) / d. Then the correct option is D.

The missing options are attached to the picture given below.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The formula for the nth term of an arithmetic sequence can be found using the formula given below.

\rm a_n = a_1 + (n-1)d

Then arrange the equation for n, we have

\begin{aligned} \rm a_n - a_1 & \rm = nd - d\\\\\rm a_n - a_1 + d & \rm =nd\\\\\rm n & \rm = \dfrac{a_n - a_1 + d}{d}  \end{aligned}

Then the correct option is D.
