Answer:

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION BELOW;

A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week. She noticed that when she reduces the price such that she earns $1 less in profit from each bouquet, she then sells three more bouquets per week. The relationship between her weekly profit, P(x), after x one-dollar decreases is shown in the graph below.

CHECK THE ATTACHMENT FOR THE GRAPH

EXPLANATION;

FIRST QUESTION:

From the graph maximum profit is the value gotten where p(X) has maximum value, and the maximum value is observed at y- axis at P(X)to be 675.

Thefore, maximum profit the florist will earn from celebration bouquet is $675.

SECOND QUESTION:

Break even is the exact point that profit p(x) is observed as zero.

Checking the given g graph the point where there is zero value of p(X) is observed at x=20 and x= -10 but we can only pick the positive value which is x=20

Therefore, the florist will break even after 20 one- dollar decreases

THIRD QUESTION;

The interval of number of one dollar decreases can be observed at the point where we have the value of P(x) been more than zero, looking at the given graph, the P(x) has its value greater than zero at the interval 0 to 20.Therefore, it can be concluded that the interval of number of one dollar decreases for which the florist makes a profit from celebration bouquet is (0, 20)

Answer:

$32.96

Step-by-step explanation:

38.50 (20%) + 7.70

38.50 - 7.70 = 30.80

:Before tax:

$30.80

30.80(7%) = $2.16

30.80 + 2.16 = 32.96

What is the length of the missing leg <br> 15 and 9 meters

Brilliant_brown [7]

Answer: 12

Step-by-step explanation: I assume you are talking about a triangle in which the Hypotenuse is 15 and leg A is 9

in this case we have to use a reverse pythagorean theorem

the original one is a^ + b^ = c^ then reverse it to get c^ - a ^ = b^

we know that C is 15 and A is 9 so substitute

15^ - 9^ = b^

15 ^ = 225 and 9^ = 81 so substitute again

225 - 81 = b^ then subtract

144 = b^ you know that the square root of 144 is 12 because 12 x 12 = 144

so 12 is the last side

hope this helps mark me brainliest if it did

How tooo do thissss?

exis [7]

Step-by-step explanation:

m/s² = m/s / s

this is the slope of the line in the graph.

t = 2, that means it is in the first segment of 0 - 6 seconds

the slope in this segment is

(25-15)m/s / (6-0)s

10m/s / 6s = 10/6 m/s² = 5/4 m/s² = 1.25 m/s² ≈ 1.3 m/s²

the same thing for t = 12 in the third segment.

the acceleration or slope is negative here, but that's called here a "forbidden word", and is therefore also a positive number.

in that this segment the slope is

(0-25)m/s / (16-11)s

-25m/s / 5s = -5 m/s²

and so, the answer is 5 m/s².

for the total distance we need to calculate the area under the lines.

the line functions in the 3 segments are :

s(t) = 5/4 t + 15

s(t) = 25

s(t) = -5t + 25

the third one is simplified by moving it from the 11 to 16 seconds interval to a 0 to 5 seconds interval. this creates the same area under that line.

the area under the first line is the integral of the line function between 0 and 6.

that is

[5/8 t² + 15t] between 0 and 6.

and that is

5/8 × 36 + 90 - 5/8 × 0 - 15×0 = 45/4 + 90

= 45/4 + 360/4 = 405/4 = 101.25m

the area under the second segment is simply the area of the rectangle 5×25 = 125m

and the area under the third segment is the integral of the line function between 0 and 5 (remember, we shifted from 11 to 16 to the interval 0 to 5).

that is

[-2.5t² + 25t] in the interval 0 to 5.

and that is

-2.5×25 + 25×5 - -2.5×0 - 25×0 = -62.5 + 125 = 62.5m

as a control check this area is also the area of a right-angled triangle with legs of 5 and 25

the area is 25×5/2 = 125/2 = 62.5

so, it is correct.

the total area under the lines is therefore

101.25 + 125 + 62.5 = 288.75 m ≈ 288.8 m

the average speed is now simply

288.75 m / 16 s = 288.75/16 m/s = 18.046875 m/s ≈

≈ 18 m/s

but if we used the already rounded result of the total distance of 288.8 m, then we would get

288.8 / 16 = 18.05 m/s ≈ 18.1 m/s

which of the following are NOT trigonometric identities, Check all that apply a.) sec^(2) x - tan^(2) x=1 b) sec^(2) x+csc^(2) x

Anit [1.1K]

By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are

sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1

So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .

So the correct options are

b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1
