Answer:

[tex]x=6,50[/tex]

Step-by-step explanation:

The revenue from their ticket sales is a function of the ticket price, x , and can be modeled with [tex](x-6)(250-5x)[/tex]

To find the two ticket prices at which the band would make no money at all, solve the following equation:

[tex](x-6)(250-5x)=0\\x-6=0\,,\,250-5x=0\\x=6\,,\,5x=250\\\\x=6\,,\,x=\frac{250}{5}\\\\x=6,50[/tex]

The two ticket prices at which the band would make no money at all is 6, 50.

Since the revenue from their ticket sales is a function of the ticket price, x , and can be modeled with (x - 6)(250 - 5x).

So here it can be like

(x - 6) (250 - 5x) = 0

x - 6 = 0, 250 - 5x = 0

x = 6, 5x = 250

x = 5, x = 50

hence, The two ticket prices at which the band would make no money at all is 6, 50.

Step-by-step explanation:

So, a line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length. The length of a line segment can be measured either in metric units such as millimeters, centimeters, or customary units like feet or inches.

 74/5 milliliters of sand accumulate in the bag from time t=0 to time t=2.

Given that:

The rate at which sand is poured is r(t)

The function r(t) is defined as;

r(t) = 15t -[tex]2t^2[/tex]

The accumulation in the bag from time t=0 to time t=2 is calculated as:

 r = [tex]\int_0^2 ( 15t -2t^2) dt[/tex]

Using the limits:

    =[tex][\dfrac{15t^2}{2} - \dfrac{2t^3}{3}]_0^2[/tex]

 =[tex]\dfrac{15(2) ^2}{2} - \dfrac{2(2)^3}{3} - (0-0)[/tex]

[tex]30 - \dfrac{16}{3}[/tex]

= [tex]\dfrac{74}{3}[/tex]

  Thus, [tex]\dfrac{74}{3}[/tex] milliliters of sand accumulate in the bag from time t=0 to time t=2.

Answer:

y = 20 [tex]4^{x}[/tex]

Step-by-step explanation:

Use the points to find the values of a and b

Using (0, 20 ) , then

20 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then

20 = a

y = 20[tex]b^{x}[/tex]

Using (3, 1280 ) , then

1280 = 20 b³ ( divide both sides by 20 )

64 = b³ ( take the cube root of both sides )

[tex]\sqrt[3]{64}[/tex] = b , that is

4 = b

Then exponential function is

Answer:

35 degrees

Step-by-step explanation:

for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?​

Let the given expression be equal to 1, hence;

csc (2x+30°)= cos (3y-15°) = 1

csc (2x+30°) = 1

1/sin(2x+30) = 1

1 = sin(2x+30)

sin(2x+30) = 1

2x+30 = arcsin(1)

2x+30 = 90

2x = 90-30

2x = 60

x = 60/2

x = 30 degrees

Get the value of y;

cos (3y-15°) = 1

3y - 15 = arccos (1)

3y - 15= 0

3y = 0+15

3y = 15

y = 15/3

y = 5

Sum of x and y;

x+y = 30 + 5

x+y = 35degrees

Hence the sum of x and y is 35 degrees

[tex]\begin{array}{cc}{Loaves} & {Banana} & {1} & {2\frac{1}{2}} & {2} & {5} & {4} & {10} \ \end{array}[/tex]

Step-by-step explanation:

Given

See attachment for number line

Required

Complete the table

From the number line;

[tex]0\ loaf = 0\ banana[/tex]

[tex]1\ loaf = 2\frac{1}{2}\ banana[/tex]

Multiply by 2 to get the equivalent of 5 bananas

[tex]2 * 1\ loaf = 2\frac{1}{2}\ banana * 2[/tex]

[tex]2 \ loaf = 5\ banana[/tex]

Multiply by 4 to get the equivalent of 4 loaves

[tex]1\ loaf = 2\frac{1}{2}\ banana[/tex]

[tex]4 * 1\ loaf = 2\frac{1}{2}\ banana * 4[/tex]

[tex]4 \ loaf = 10\ banana[/tex]

So, the complete table is:

[tex]\begin{array}{cc}{Loaves} & {Banana} & {1} & {2\frac{1}{2}} & {2} & {5} & {4} & {10} \ \end{array}[/tex]

Answer:

The two numbers are 6 and 19

Step-by-step explanation:

Assume that the two numbers are x and y

We are given that:

The sum of the two numbers is 25

This means that:

x + y = 25 ..........................> equation 1

We are also given that:

One number is twice the other plus 7

This means that:

x = 2y + 7 ..........................> equation 2

Substitute with equation 2 in equation 1 and solve for y:

2y + 7 + y = 25

3y + 7 = 25

3y = 18

y = 6

Now, substitute with the value of y in equation 2 to get x as follows:

x = 2y + 7

x = 2(6) + 7

x = 12 + 7

x = 19

Based on the above, we can conclude that the two numbers are:

6 and 19

Hope this helps :)

x+y=25 => x=-y+25

x= 2y+7

x=-y+25

x=2y+7

subtract the first equation from the 2nd

0=3y-18

y=6

x=19

Answer:

15 years old

Step-by-step explanation:

bailey is 12, and cala is 6

6 + 9 = 15

12+ 3 = 15

The age of antoine should be considered as the 15 years old when balley is twice to cala. And, to understand the calculations check below.

Since

Bailey is twice as old as Cala. Antoine is 9 years older than Cala and ​3 years older than Bailey.

So based on this, we can say that

Here we assume Cala age be x

So, Bailey age be 2x

Now Antoine age be 9 + x

And, 3 + 2x

So,

9 - x = 3 - 2x

9 - 3 = x

x = 6

So here Cala age be 6

Bailey age be 12

So ,here the Antoine age be

= 9 + 6
