<dpb because they’re vertical angles (they’re directly across from each other)

Answer: The required angle that is always congruent to angle APC is angle BPD.

Step-by-step explanation: Given that in the diagram shown, the lines AB and CD intersect each other at the point P.

We are to name the angle that is always congruent to angle APC.

We know that

when two straight line intersect each other, we get two pairs of vertically opposite angles.

The two angles in each pair of vertically opposite angles are congruent to each other.

So, here the lines AB and CD are intersecting at the point P and the two pairs of vertically opposite angles are

(∠APC and ∠BPD) and (∠BPC and ∠APD).

Therefore, we get

∠APC ≅ ∠BPD and ∠BPC ≅ ∠APD.

Thus, the required angle that is always congruent to angle APC is angle BPD.

The total revenue R earned (in dollars) from producing a gift box of candles is given by R(p)=-10p^2+800p, where p is the price

kherson [118]

A.) R(20) = -10(20)^2 + 800(20) = -10(400) + 16000 = -4000 + 16000 = $12,000

R(25) = -10(25)^2 + 800(25) = -10(625) + 20000 = -6250 + 20000 = $13,750

R(30) = -10(30)^2 + 800(30) = -10(900) + 24000 = -9000 + 24000 = $15,000

b.) For maximum revenue, dR/dp = 0
dR/dp = -20p + 800 = 0
20p = 800
p = 40

Therefore, the maximum revenue will be recorded when the price is set at $40.

Creating an Exponential Model

belka [17]

Answer:

P = $300

r = 0.15

n = 12

$544.61 (to the nearest cent)

$P(1+r)^t$

$524.70 (to the nearest cent)

Step-by-step explanation:

P = principal amount = $300

r = annual interest rate in decimal form = 15% = 15/100 = 0.15

n = number of times interest is compounded per unit t = 12

How much she'll owe in 4 years

P = 300

r = 0.15

n = 12

t = 4

$P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}$

= $544.61 (to the nearest cent)

Yearly compounding interest rate

$P(1+r)^t$

How much she'll owe in 4 years at yearly compounding interest

$P(1+r)^t=300(1+0.15)^4$

= $524.70 (to the nearest cent)

I need some help with my answer! Most helpful gets brainliest!

If f(x) is given with points (0,5) and (4,3), it can be easily plotted in a coordinate system (see .jpeg image in attachment).If g(x) is a function defined by text:

Kyle started the summer having read 3 books but plans to read 6 books per month over the summer.Then, g(x) is given with:

g(x) = 6*x+3 (3 books read already, and 6 books will be read each month).h(x) is already given with:

h(x)=3*x+4

These all three functions are plotted in coordinate system and it can be seen that the lowest y-intercept has function g(x), and it is the value of 3 on y-axis. Others have 4 (h(x)) and 5 (f(x)).
