Hello!!! Princess Sakura here ^^

Step-by-step explanation:

In all of these I just plugged in for x

Checking choice (1):

[tex]2x+1>15\\2(9)+1>15\\18+1 >15\\19>15[/tex]

This is true so it's not the right answer.

________________________________________________________

Checking choice (2):

[tex]2x+1>15\\2(7)+1>15\\14+1>15\\15>15[/tex]

This is false so this is the answer.

But we'll just check the others just in case.

_________________________________________________________

Checking choice (3):

[tex]2x+1>15\\2(10)+1>15\\20+1>15\\21>15[/tex]

This is true so it can't be the answer.

_________________________________________________________

Checking choice (4):

[tex]2x+1>15\\2(15)+1>15\\30+1>15\\31>15[/tex]

This is true so it can't be the answer.

Now we found out that the answer is Choice 2.

Answer:

(1,7)

Step-by-step explanation:

in order for something to be a function, each x value can only have one y value (vertical line test). because all of the other answers use x values that were previously assigned a y value, (1,7) is the only one that works.

Answer:

53m

Step-by-step explanation:

Let x = the width

Let y = the length

5x + 3 = y

2x + 2y = 126

Plug in 5x + 3 for y in the second equation

2x + 2(5x + 3) = 126

Distribute the 2

2x + 10x + 6 = 126

Combine like terms

12x + 6 = 126

Subtract 6 from both sides

12x = 120

Divide both sides by 12

[tex] \frac{12x}{12} = \frac{120}{12} [/tex]

x = 10

Remember x = width. You are looking for length.

y = 5x + 3

y = 5(10) + 3

y = 50 + 3

y = 53

Answer:

A

Step-by-step explanation:

Answer:

It's A 30%

Step-by-step explanation:

Answer:

y=1600

x=2400

Step-by-step explanation:

x+y=4000

solve for a variable

x=4000-y

plug this into .06x+.11y=320 (the interest from account 1 + account 2 must equal 320)

.06(4000-y)+.11y=320

240-.06y+.11y=320

minus 240 both sides

-.06y+.11y=80

combine terms

.05y=80

divide by .05

y=1600

to find x you subtract 1600 from 4000 to get 2400

remember, your equation must be x+y=4000

x+1600=4000

-1600

x=2400

Tanya has 26 quarters and 18 dimes.

Given that Tanya has 44 quarters and dimes which worth $8.30, we need to find the number of each coin type,

To find the same we will use the concept of system of Linear equations,

Let's solve this problem step by step.

Let's assume Tanya has x quarters and y dimes.

The value of x quarters is 25x cents.

The value of y dimes is 10y cents.

According to the given information, the total value of the quarters and dimes is $8.30, which is equivalent to 830 cents. So we have the equation:

25x + 10y = 830 ...........(Equation 1)

Tanya has 44 coins in total:

x + y = 44 ...........(Equation 2)

Now, we can solve this system of equations (Equation 1 and Equation 2) to find the values of x and y.

Multiplying Equation 2 by 25, we get:

25x + 25y = 1100 ...........(Equation 3)

Subtracting Equation 3 from Equation 1, we eliminate the x term:

25x + 10y - (25x + 25y) = 830 - 1100

-15y = -270

Dividing both sides by -15, we get:

y = (-270)/(-15) = 18

Substituting the value of y back into Equation 2, we can find x:

x + 18 = 44

x = 44 - 18 = 26

Therefore, Tanya has 26 quarters and 18 dimes.

Answer:

The value is  [tex]n_2 = 260[/tex]

Step-by-step explanation:

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the width of  a confidence interval is dependent on the margin of error which is mathematically represented as

      [tex]E = Z_{\frac{\alpha }{2} } * \frac{ \sigma}{\sqrt{n} }[/tex]

Here [tex]\sigma[/tex] is the standard deviation  

Let assume that [tex]\sigma[/tex] and  [tex]Z_{\frac{\alpha }{2} } [/tex] are constant for the width of the confidence interval when the sample size is  n =65 and now that it has been divided to two

=>  [tex]E = \frac{ K }{\sqrt{n} }[/tex]

Here  K is a constant  

=>   [tex]E * \sqrt{n} = K[/tex]

=>    [tex]E_1 * \sqrt{n}_1 = E_2 * \sqrt{n}_2[/tex]

Now let [tex]E_1 \ and \ n_1[/tex] be the margin of error and sample size before the reduction

  So [tex]n_1 = 65[/tex]

and let [tex]E_2 \ and \ n_2[/tex] be the margin of error and sample size after the reduction  

    So  [tex]E_2 = \frac{1}{2} E_1[/tex]

=>   [tex]E_1 * \sqrt{65} = \frac{E_1}{2} * \sqrt{n}_2[/tex]

=>   [tex]\sqrt{65} = \frac{1}{2} * \sqrt{n}_2[/tex]

=>   [tex]n_2 = 260[/tex]

The new function after the transformation becomes as y = eˣ⁻⁷ + 5. The correct option is (d).

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is  f(x + a).

And, for up and down shift it is a + f(x) and a - f(x) respectively.

Given that,

The graph of y = eˣ is translated 7 units to the right and 5 units upward.

According to the rule of transformation for a graph, when a function is shifted righwards, it becomes as f(x - a) and when it is shifted upwards it becomes a + f(x).

Apply the above mentioned rule for the given function to obtain,

y = eˣ⁻⁷ + 5

Hence, the function resulting after being shifted 7 units rightwards and 5 units upwards is y = eˣ⁻⁷ + 5.

Answer:

Step-by-step explanation:

Solve equation [2] for the variable  x  

 [2]    3x = 2y - 6

 [2]    x = 2y/3 - 2

Plug this in for variable  x  in equation [1]

  [1]    5•(2y/3-2) + 6y = -10

  [1]    28y/3 = 0

  [1]    28y = 0

Solve equation [1] for the variable  y  

  [1]    28y = 0  

  [1]    y = 0  

By now we know this much :

   x = 2y/3-2

   y = 0

Use the  y  value to solve for  x

Answer:

48 meters

Step-by-step explanation:

First, use trigonometric ratios formula to find the distance of each of them from the tower. The difference between their distance from the tower will give you the distance they stood apart from each other.

Distance of the first person from the Tower with am angle of elevation of 25°:

Height of the tower = 30 meters (opposite side)

Distance from the tower = x (adjacent side)

[tex] tan(25) = \frac{opp}{adjacent} [/tex]

[tex] tan(25) = \frac{30}{x} [/tex]

Multiply both sides by x

[tex] tan(25)*x = 30 [/tex]

Divide both sides by tan(25)

[tex] x = \frac{30}{tan(25)} [/tex]

[tex] x = 64 m [/tex] (nearest whole number)

Distance of the second person from the Tower with am angle of elevation of 15°:

Height of the tower = 30 meters (opposite side)

Distance from the tower = x (adjacent side)

[tex] tan(15) = \frac{opp}{adjacent} [/tex]

[tex] tan(15) = \frac{30}{x} [/tex]

Multiply both sides by x

[tex] tan(15)*x = 30 [/tex]

Divide both sides by tan(15)

[tex] x = \frac{30}{tan(15)} [/tex]

[tex] x = 112 m [/tex] (nearest whole number)

Distance between both of them = 112 - 64 = 48 meters

A 6-ft-tall person walks away from a 11-ft lamppost at a constant rate of 3.3 ft/sec. What is the rate that the tip of the person's shadow moves away from the lamppost when the person is 11 ft away from the lampost?

Answer:

7.26ft/s

Step-by-step explanation:

A 6-ft-tall person walks away from a 11-ft lamppost at a constant rate of 3.3 ft/sec. What is the rate that the tip of the person's shadow moves away from the lamppost when the person is 11 ft away from the lampost?

Let x = distance of person to the tip of the lamp post

= 6/x = 11/d

Cross Multiply

6d = 11 x....... Equation 1

The constant rate of the person = 3.3 ft/s

= Distance of the person to the pole = Speed × time

= 3.3 × t

d = 3.3t

x = d - 3.3t

Substitute d - 3.3t for x in Equation 1

6d = 11x

6d = 11(d - 3.3t)

6d = 11d - 36.3t

36.3t = 11d - 6d

36.3t = 5d

d = 36.3/5

d = 7.26 ft/s
