I think it’s b I’m currently learning the same thing in my class

Answer:

The answer is A. 2.0

Step-by-step explanation:

One of the angles is a right angle, because x is the tangent of that circle. The other radius is 1.5, since all radius are equal to each other. Then you use the Pythagorean theorem (a²+b²=c²). C is always the hypotenuse. The hypotenuse in this triangle is the 1.5 + 1 line. A and b can be changed within each other. I put A = 1.5, B = x, and C = 2.5. My equation was 1.5²+x²=2.5². Remember the formula can also be x²+1.5²=2.5² as well. Then you solve the equation you just made. You multiply everything by each other, because of the ² (I forgot the name of it, hehehe). You will get 2.25+x²=6.25. Then you subtract 2.25 to both side. x²= 4. Then you square root both sides to make x by itself. x=2. That's how you get 2 as your answer

Answer:

Step-by-step explanation:

t(1) = 4

t(n) = -4 * t(n - 1)

common ratio: -4

t(1) = -4 * t(0)

4 = -4 * t(0)

t(0) = -1

t(n) = -4n * -1

t(1) = -4 (1) * -1

= 4

t(n) = -4n * -1

t(6) = -4*6 * -1

t(6) = 24

I think the answer is most likely 80

8 times because you take 4 times 2 and get 8

Reasoning:

There are 2 outcomes if you flip only one coin (H or T).

There are 2^2 = 2*2 = 4 outcomes if you flip two coins (HH, HT, TH, TT).

There are 2^3 = 2*2*2 = 8 outcomes if you flip three coins.

There are 2^4 = 2*2*2*2 = 16 outcomes if you flip four coins.

Answer:

C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.

Step-by-step explanation:

The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept.

In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.

In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.

To solve the equations graphically, graph them and find the point where they intersect.

Final answer:

To find the probability that the red die shows an even number or the green die shows an even number, we can use the concept of probability of a union of two events. The probability is 3/4.

Explanation:

To find the probability that the red die shows an even number or the green die shows an even number, we can use the concept of probability of a union of two events. Let's denote the event that the red die shows an even number as E and the event that the green die shows an even number as F.

Since each die has 6 equally likely outcomes, the probability of rolling an even number on the red die is P(E) = 3/6 = 1/2, and the probability of rolling an even number on the green die is P(F) = 3/6 = 1/2.

To find the probability of the union of two events (E or F), we add the probabilities of E and F and subtract the probability of their intersection (E and F) to avoid double-counting. In this case, the intersection is the event that both dice roll an even number, which has a probability of P(E and F) = (1/2) × (1/2) = 1/4.

Therefore, the probability that the red die shows an even number or the green die shows an even number is P(E or F) = P(E) + P(F) - P(E and F) = 1/2 + 1/2 - 1/4 = 3/4.

Answer:

y = 15x + 20

Step-by-step explanation:

He charges a flat rate of $20, so any total for hours worked will have an additional $20 added to it.  

The 15x represents his earnings per hour.  He makes 15 per every hour worked, x represents the number of hours worked

Again, scale factor is 12 / 4 = 3.

So Perimeter = 16 * 3 = 48.

The perimeter of the larger flag, which is a square with each side measuring 8 inches, is 32 inches. This is calculated by multiplying the side length by 4, as a square has four sides.

To find the perimeter of the larger flag, which resembles a larger square, you need to know the length of one of its sides. Since the problem states that the dimensions are twice that of a smaller square, first, determine the side length of the smaller square. If the side length of the larger square is 8 inches, obtained by scaling up the smaller square's side length by a factor of 2 (4 inches x 2 = 8 inches), you can find the perimeter by multiplying the side length of the larger square by 4 (since a square has four sides).

The calculation for the perimeter of the larger square is as follows: 8 inches x 4 = 32 inches. Therefore, the perimeter of the larger flag is 32 inches.

Step-by-step explanation:

First we have to find percent change by doing change/original

To find change: 45000-18000=27000

Now divide by original. 27000/18000=1.5

The change was 150 percent. Now we multiply 45000 by 150 percent to get the projected population for 2015.

45000*1.5=67500 people

Projected population for 2015 using exponential growth model is 112,500, calculated with initial population of 18,000 and growth rate.

To determine the projected population for 2015 using an exponential growth model, we need to identify the growth rate and use it to extrapolate the population.

The exponential growth model can be represented as:

[tex]\[ P(t) = P_0 \times e^{rt} \][/tex]

Where:

- [tex]\( P(t) \)[/tex] is the population at time [tex]\( t \)[/tex]

- [tex]\( P_0 \)[/tex] is the initial population (in 2005)

- [tex]\( r \)[/tex] is the growth rate

- [tex]\( t \)[/tex] is the time in years since the initial population was measured

First, we need to find the growth rate [tex](\( r \))[/tex]. We can use the data provided from 2005 to 2010:

[tex]\[ P_0 = 18000 \][/tex]

[tex]\[ P(5) = 45000 \][/tex]

Using these values in the formula:

[tex]\[ 45000 = 18000 \times e^{5r} \][/tex]

Now, let's solve for [tex]\( r \)[/tex]:

[tex]\[ \frac{45000}{18000} = e^{5r} \][/tex]

[tex]\[ 2.5 = e^{5r} \][/tex]

Taking the natural logarithm of both sides:

[tex]\[ \ln(2.5) = 5r \][/tex]

Now, divide by 5:

[tex]\[ r = \frac{\ln(2.5)}{5} \][/tex]

Now, we have the growth rate [tex]\( r \)[/tex]. We can use this rate to project the population for 2015 [tex](\( t = 10 \) years)[/tex]:

[tex]\[ P(10) = 18000 \times e^{\frac{\ln(2.5)}{5} \times 10} \][/tex]

Now, calculate this:

[tex]\[ P(10) = 18000 \times e^{\ln(2.5) \times 2} \][/tex]

[tex]\[ P(10) = 18000 \times e^{\ln(2.5^2)} \][/tex]

[tex]\[ P(10) = 18000 \times e^{\ln(6.25)} \][/tex]

[tex]\[ P(10) = 18000 \times 6.25 \][/tex]

[tex]\[ P(10) = 112500 \][/tex]

So, the projected population for 2015 is 112,500.

Answer:

[tex]40 +20 = 72 -12\\\\60 = 60[/tex]

Step-by-step explanation:

If we have an expression in the following way:

[tex]c(a + b)[/tex]

So the distributive property says that:

[tex]c(a + b) = ca + cb[/tex]

In this case we have the expression:

[tex]4(10 + 5) = 6(12-2)[/tex]

Therefore we can rewrite it as:

[tex]4 * 10 + 4 * 5 = 6 * 12 -2 * 6[/tex]

Then we have left:

[tex]40 +20 = 72 -12\\\\60 = 60[/tex]

4*10+4*5=6*12-6*2

40+20=72-12

60=60

Answer: 60=60

Answer:

y-7 = 4(x--9)

y-7 = 4(x+9)

Hey there!

The first thing we should do is to make the fractions have a common denominator.

The least common multiple of 4 and 6 is 12, which we can find by taking the multiples of both and finding the smallest one they have in common.

What we should do it multiply both sides of the equation by 12, which eliminates both fractions.

We now have:

9x - 60 = 10

The results of the equation without fraction is 118x = 175

Given the equation

[tex]\frac{3}{5} x - 5 = \frac{5}{6}\\[/tex]

Step 1: Add 5 to both sides of the equation:

[tex]\frac{3}{5} x - 5 +5= \frac{5}{6} + 5\\\frac{3}{5} x= \frac{5}{6} + 5\\[/tex]

Multiply through by 30:

[tex]\frac{3}{5} x \times 30= (\frac{5}{6} \times 30 )+( 5 \times 30)\\(3x \times 6) = (5\times 5) + 150\\18x = 25 + 150\\18x = 175[/tex]

Hence the result of the equation without fraction is 118x = 175

Answer: 26.8 feet

Step-by-step explanation:

In the figure attached you can see two right triangles  triangle ABD and a triangle ACD.

You are located at point B and the other person at point C.

The approximate height of the lifeguard station is x.

Keep on mind that:

[tex]tan\alpha=\frac{opposite}{adjacent}[/tex]

Therefore:

For the triangle ABD:

[tex]tan(36\°)=\frac{x}{DC+11}[/tex]    [EQUATION 1]

For the triangle ACD:

[tex]tan(46\°)=\frac{x}{DC}[/tex]    [EQUATION 2]

Solve from DC from [EQUATION 2]:

[tex]DC=\frac{x}{tan(46\°)}[/tex]

Substitute into [EQUATION 1] and solve for x:

[tex]tan(36\°)=\frac{x}{(\frac{x}{tan(46\°)}+11)}\\tan(36\°)(\frac{x}{tan(46\°)}+11)=x\\11*tan(36\°)=x-\frac{xtan(36\°)}{tan(46\°)}\\7.991=0.298x[/tex]

[tex]x=26.81ft[/tex]≈26.8ft
