How many types of symmetry are there?

PtichkaEL [24]

Answer:

a) C = 250 + 1.25n

b) 1800

c) 300

Step-by-step explanation:

a) To write the equation for these problems, let's establish the constant, $250, since we are given that $250 is a FIXED cost, meaning no matter how many brochures we print, we will have to pay $250. Then, we have to pay $1.25 for each brochure, so for n amount of brochures, so we have 1.25*n. Putting it together, we have the fixed cost + the cost of producing n brochures, C = 250 + 1.25C

b) The cost of printing 2500 brochures can be found by pluggin number into the equation above. C = 250 + 1.25*2500 = $1800

c) This is the opposite question, since 625 is the final cost, we plug it into the final cost, 625 = 250 + 1.25*n. Solving gives n = 300

Can someone help me with some algebra?

★ Oblique Asymptote ★

$f(x) = \frac{x {}^{2} + 5x + 6}{x - 4} \\ f(x) = (x - 4)(x + 9) + 42 \\$
Hence , oblique Asymptote is obtained simultaneously by the Quotient of the function obtained ,
HENCE , oblique Asymptote is
$y = x + 9$

(Mhanifa) please solve this question thank you!

ivanzaharov [21]

Answer:

Option A

Step-by-step explanation:

A'B' is 1/2 times the AB as the scale factor is 1/2.

<u>Find the length of AB using distance formula.</u>

AB = $\sqrt{(4 - 2)^2 + (4-0)^2} = \sqrt{20} = 2\sqrt{5}$

A'B' = 1/2*2 $\sqrt{5} = \sqrt{5}$

Correct choice is A

CD is perpendicular to AB and passes through point C5, 12).

Aleksandr-060686 [28]

Answer:

x intercept of CD = 17

Step-by-step explanation:

We are given a line AB with its end coordinates. and Another line segment CD which is perpendicular to AB. We have the coordinates of C , and we are asked to find the x intercept of line CD.

For that we need to find the equation of CD

we have coordinates of C , and hence if we have slope of CD we can find equation of CD

Slope of CD can be determine with the help of slope of AB as CD⊥ AB

So, the slope of CD $mCD = -\frac{1}{mAB}$
