Answer:

Thus last month Calvin made $414.90 from all the paintings sold at the art shows.

Step-by-step explanation:

Let us first analyse the given information in the question:

→ Small paints (lets call them $s$ ) sell for $25.80 Per Painting, thus:

$25.80s$ gives as the profit for $s$ number paints sold.

→ Large paints (lets call them $l$ ) sell for $56.25 Per Painting, thus:

$56.25l$ gives as the profit for $l$ number paints sold.

We also know last month he sold six large paintings and three small paintings thus from our variables above we can say:

$s=3\\l=6$ Eqn(1).

Thus the total profit of all paintings sold would be:

$PROFIT= 25.80s+56.25l$ which by pluggin in Eqn(1) values gives

$PROFIT=25.80*3+56.25*6\\PROFIT=414.90$

Thus last month Calvin made $414.90 from all the paintings sold at the art shows.

1.) Evaluate the indicated function, where f(x) = x2 − 8x + 3and g(x) = 7x − 5.

noname [10]

Answer:

1) (f + g) (5) = 18, 2) (f + g) (1/2) = - 13/4, 3) (f - g) (-1) = 14, 4) (f * g) (7) = 456, 5) (f/g) (- 2) = - 3/4, 6) (g ○ f)(x) = 6 x - 23, (f ○ g)(x) = 6 x - 6, 7) $(g \circ f) (x) = \frac{9}{x} - 24$ , $(f \circ g) (x) = \frac{1}{x - 2} + 5$ , 8) (f ○ g)(5) = 3

Step-by-step explanation:

1) $(f + g) (x) = x^{2}-8\cdot x + 3 + 7 \cdot x - 5\\(f + g) (x) = x^{2} - x - 2\\(f + g) (5) = 18$

2) $(f + g) (x) = x^{2} - 7 \cdot x + 4 + 6 \cdot x - 7\\(f + g) (x) = x^{2} - x - 3\\(f + g) (\frac{1}{2} ) = - \frac{13}{4}$

3) $(f - g) (x) = x^{2} - 3 \cdot x + 4 - 4 \cdot x + 2\\(f - g) (x) = x^{2} - 7 \cdot x + 6\\(f - g) (-1) = 14$

4) $(f \cdot g) (x) = (x^{2}-4\cdot x + 3) \cdot (3\cdot x - 2)\\(f \cdot g) (7) = 456$

5) $(f / g) (x) = \frac{x^{2}-3\cdot x + 2}{4 \cdot x - 8} \\(f / g) (-2) = - \frac{3}{4}$

6) $(g \circ f) (x) = 3 \cdot (2 \cdot x - 8) + 1\\(g \circ f) (x) = 6 \cdot x - 23\\(f \circ g) (x) = 2 \cdot (3 \cdot x + 1) - 8\\(f \circ g) (x) = 6 \cdot x - 6$

7) $(g \circ f) (x) = 3 \cdot (\frac{3}{x} - 6) - 6\\(g \circ f) (x) = \frac{9}{x} - 24\\(f \circ g) (x) = \frac{3}{3 \cdot x - 6} + 5\\(f \circ g) (x) = \frac{1}{x - 2} + 5$

8) $(f \circ g) (x) = 2 \cdot (x^{2} - 5 \cdot x) + 3\\(f \circ g) (x) = 2 \cdot x ^{2} - 10 \cdot x + 3\\(f \circ g) (5) = 3$

1. the shape is a parallelogram. what is the measure of KL?

aleksklad [387]

Answer:

1. KL = 29

2. angle J = 127 degree

3. angle of K = 53 degrees

Step-by-step explanation:

SInce it is a parrallelograme, one thing that will help you is to remember that opposits are the same.

1. KL = JM since they are opposite => KL = 29

2. angle J = angle L since they are opposite => angle J = 127 degrees

3. Since we know that angle J and L are both equal to 127 degree and since the sum of the angles of a parralelogram is 360 degrees, so the sum of the angles of K and M is: 360 - 127 - 127 = 106 degrees.

Since K's and M's angles are equale => 106 / 2 = 53 degrees.
