In the formula, l = a + (n - 1)d make d as the subject. Find d when l = 10, a = 2, n = 5.

coldgirl [10]

<h3>Given:-</h3>

I = a + (n - 1)d [Given formula]

Find d when I = 10, a = 2, n = 5

<h2>Solution:-</h2>

I = a + (n - 1)d [Given]

Putting the value of I = 10, a = 2, n = 5 we get,

10 = 2 + (5 - 1)d

10 = 2 + 4d

10 - 2 = 4d

8 = 4d

d = $\frac{8}{4}$

d = 2

<h3>Value of d is 2. [Answer]</h3>

Quadrilateral HIJK has sides measuring 12 cm, 26 cm, 14 cm, and 30 cm. Which could be the side lengths of a dilation of HIJK wit

matrenka [14]

Answer:

Step-by-step explanation:

The quadrilateral HIJK has sides measuring 12 cm, 26 cm, 14 cm, and 30 cm.

When HIJK is dilated with a scale factor of 1.5, the side lengths becomes:

12 X 1.5 =18 cm

26 X 1.5 =39 cm

14 X 1.5 =21 cm

30 X 1.5 =45 cm

A dilation of HIJK with a scale factor of 1.5 will give us the side lengths:

18cm, 39cm, 21cm and 45cm.

The correct option is C.

The function f(x) = 20(3)^x represents the growth of a fish population every year in a local lake. Jesse wants to manipulate the

valentina_108 [34]

We need the exponents law

$a^{bx}=(a^b)^x$
So if
a=3
b=1/2

then
$3^{1/2*x}=(3^{1/2})^x$
where x represent every half a year.
