raketka [301]

Answer:

63j

Step-by-step explanation:

Multiply 2j by 9 and 5j by 9. This gets you to 18j+45j. Then, add these since they are like terms: 63j.

Identify the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector &lt;−6, 3&gt;.
jarptica [38.1K]

Answer:

P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)

Step-by-step explanation:

The translation vector, ⟨−6,3⟩, can be used to derive a rule for the translation of the coordinates: (x,y)→(x−6,y+3).

Apply the rule to translate each of the three preimage vertices to the image vertices.

P(−4,−5)→P'(−10,−2)

L(1,−7)→L'(−5,−4)

K(−9,8)→K'(−15,11)

Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.

Enrollment in a school has grown exponentially since the school opened. A graph depicting this growth is shown. Determine the pe
Yanka [14]

Answer:

4.6%

Step-by-step explanation:

Let the horizontal axis be represented by x and the vertical axis be represented by f(x) or y

The general exponential function is of the form:

f(x) = a(b)^{x}

Here,

a = value at the starting of the graph

b = growth factor

In order to find the percentage rate of growth, we need to find the value of b, the growth factor. From the graph we can see two points on the graph: (20, 80) and (25, 100). This means for x = 20, value of f(x) is 80. Using this point in the function equation, we get:

80 = a(b)^{20}                             Equation 1

Using the second point (25, 100) in the function equation, we get:

100 = a(b)^{25}                             Equation 2

Dividing Equation 2 by Equation 1, we get:

\frac{100}{80}=\frac{ab^{25}}{ab^{20}}\\\\ 1.25=b^{5}\\\\ b=1.046

Using the value of b, the function equation becomes:

f(x) = a(1.046)^{x}

This means, after every year, the number of enrollments is 1.046 times the previous year. Or in other words, the number of enrollment is 0.046 times more the previous year. This shows the number of enrollments grow by 0.046 every year which is equal to 4.6%

Thus, the percentage rate of growth is 4.6%
