Step-by-step explanation:

To find m, we need to divide 2/5 from both sides of the equation given.

<u>Divide:</u>

<u /> $\frac{2/5}{2/5} x=\frac{17/4}{2/5}$

<u>Solving Dividing:</u>

2/5 cancels out.

$\frac{17}{4} \div \frac{2}{5} =\frac{17}{4} \times\frac{5}{2} =85/8$

<u>Equation:</u>

$x=\frac{85}{8}$

$x =10.625, or: 10\frac{5}{8}$

Find an for the arithmetic series with s16 = -288 And a1 =-21

Maru [420]

If $d$ is the common difference between terms in the sequence $\{a_n\}$ , then

$a_1=-21$
$a_2=a_1+d=-21+d$
$a_3=a_2+d=-21+2d$
...
$a_n=a_{n-1}+d=\cdots=-21+(n-1)d$

You're told that $S_{16}=-288$ (the sum of the first 16 terms in the sequence, presumably). Well, we know that

$S_{16}=\displaystyle\sum_{n=1}^{16}a_n=\sum_{n=1}^{16}(-21+(n-1)d)$
$S_{16}=\displaystyle(-21-d)\sum_{n=1}^{16}1+d\sum_{n=1}^{16}n$

Recall that

$\displaystyle\sum_{n=1}^kn=\frac{k(k+1)}2$

so that we have

$-288=16(-21-d)+\dfrac{16(16+1)}2d\implies d=\dfrac25$

So we get

$\begin{cases}a_1=-21\\\\a_n=-21+\dfrac25(n-1)\end{cases}$

The value of (fg)(x)= 3x³+ x²

<h3>What is function?</h3>

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given:

f(x) = -3x+1

g(x) = $x^{2}$

Now, (fg)(x)

=f(x) * g(x)

= (-3x+1) * ( $x^{2}$ )

=-3x³+ x²

Hence, (fg)(x)= 3x³+ x²

Linda walked 3/4 of the length of the Tremont Trail before stopping for a rest. How far had Linda walked on the trail? Tremont T

Afina-wow [57]

Answer:

2 5/8 miles or 2.625 miles

Step-by-step explanation:

We are told in the question that

Linda walked 3/4 of the length of the Tremont Trail before stopping for a rest.

From the question, the length of the Tremont Trail = 3 1/2 miles

Hence, the distance (how far )Linda has walked =

3/4 of 3 1/2 miles

= 3/4 × 3 1/2 miles

= 3/4 × 7/2 miles

= 21/8 miles

= 2 5/8 miles or 2.625 miles

Therefore, Linda had walked 2 5/8 miles or 2.625 miles on the Tremont trail
