Answer:

(h*h)(10) is the same as h(10)*h(10). Let's find the value of h(10) first. To do this, replace every x with 10 like so

Step-by-step explanation:

h(x) = 6-x

h(10) = 6-10

h(10) = -4

So,

h(10)*h(10) = (-4)*(-4)

h(10)*h(10) = 16

The final answer is 16

Answer:

7. A=48

8.B=30

9. C=188

10. D=18

11. X=32

12.Y=40

Step-by-step explanation:

Answer:

7. \(a=48\)

8. \(b=30\)

9. \(c = 188\)

10. \(d = 18\)

11. \(x = 32\)

12. \(y = 40\)

Step-by-step explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

\(\frac{33}{a} = \frac{11}{16}\)

\(11 a = 33(16)\)

\(11a = 528\)

Now we can simplify.

\(a=48\)

So we got the answer for the first one. We can keep doing the same thing for the others.

Step-by-step explanation:

20 lb of a dried fruit and granola blend 50% dried fruit

mixing 20% dried fruit x lbs

60% dried fruit y lbs

x+y=20 so x=20-y

0.2x+0.6y =0.5*20 =10

0.2(20-y) +0.6y=10

4 -0.2y+0.6y =10

0.4y =6

y=15

x=5

the first five terms of the sequence are:

-4/5, -8/5, -12/5, -16/5, -4

To find the first five terms of the sequence with the nth term given by an = -4/5n, we substitute the values of n from 1 to 5 into the nth term expression.

For n = 1:

a1 = -4/5(1) = -4/5

For n = 2:

a2 = -4/5(2) = -8/5

For n = 3:

a3 = -4/5(3) = -12/5

For n = 4:

a4 = -4/5(4) = -16/5

For n = 5:

a5 = -4/5(5) = -20/5 = -4

The exponential function that satisfies the given conditions is\(f(x) = 357e^{(-x)} + 72.\)

The exponential function that satisfies the given conditions is \(f(x) = 357e^{(-x)} + 72\).

This function has a horizontal asymptote at y = 72, indicating that as x approaches infinity, the function approaches a value of 72. The y-intercept is 429, which means that when x = 0, f(x) equals 429.

The function also passes through the point P (1, 645/4), which means that when x = 1, f(x) equals 645/4.

The value of a, which determines the overall scaling of the function, is not explicitly given. However, it can be calculated by substituting the coordinates of point P into the function and solving for a.

By substituting x = 1 and f(x) = 645/4 into the function, we can solve for a and find that a = 5/4.

In summary, the exponential function that satisfies the given conditions is \(f(x) = 357e^{(-x)} + 72\), with a = 5/4.

The operations done first are:

a)  42 (17 – 15) / (3 + 1) – 5 ; (17 -15) or (3 + 1) (parenthesis) are done first

b)  42 (17 – 15) / (3 + 1) – 5 ; 7 × 2 (multiplication) is done first

Step-by-step explanation:

from the mnemonic PEDMAS, the order of operations are: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

hence in the first expression : 42 (17 – 15) / (3 + 1) – 5, the parenthesis (bracket is simplified first as follows:

(17 - 15) = (2) ;  and (3 + 1) = (4) ;  hence the expression will be simplified as follows: 42 (2) / (4) - 5.

Next, since there is no exponent in the expression, Multiplication follows:

42 (2) = 42 × 2 = 84 ; hence he expression becomes: 84 / 4 - 5

Next division follows : 84/4 = 21, therefore the expression becomes

21 - 5.

Finally, subtraction follows : 21 - 5 = 16

b)  5 + 7 x 2 - 9;

first, multiplication is done: 7 × 2 = 14, hence the expression becomes :

5 + 14 - 9.

Next in the order is addition : 5 + 14 = 19, hence, the expression becomes:

19 - 9.

Finally, subtraction follows: 19 - 9 = 10

If someone says they will meet you again in 31 days on a Monday, then that meeting would occur on a week day of Thursday. so, the correct answer is E).

To determine the day of the week that is 31 days from a Monday, we can use the fact that there are seven days in a week. Since 31 is not evenly divisible by 7, we cannot simply add or subtract a certain number of days to find the day of the week.

Instead, we must use modular arithmetic. Specifically, we can take the remainder of 31 divided by 7, which is 3. This means that after 31 days, we will be three days ahead of Monday, so the day will be Thursday. Therefore, the day of the week that is 31 days from a Monday is Thursday.

The expression for the square of the fifth term in the ascending geometric sequence is a1^2 * r^8.

To determine the expression for the square of the fifth term in the ascending geometric sequence, let's denote the common ratio as r and the first term as a1.

The general formula for the nth term of a geometric sequence is given by:

an = a1 * r^(n-1)

In this case, we are interested in the fifth term, so n = 5:

a5 = a1 * r^(5-1)

  = a1 * r^4

To find the square of the fifth term, we square the expression for a5:

(a5)^2 = (a1 * r^4)^2

      = a1^2 * (r^4)^2

      = a1^2 * r^8

Therefore, the expression for the square of the fifth term in the ascending geometric sequence is a1^2 * r^8.

I just use desmos to graph it and find the line of fit.

The probability that a teenager plays varsity sports, given that they play a team sport, is approximately 0.4884 or 48.84%.

To find the probability that a teenager plays varsity sports given that they play a team sport, we can use conditional probability.

Let's denote:

A: Playing varsity sports

B: Playing a team sport

We are given:

P(B) = 43% = 0.43 (Probability of playing a team sport)

P(A) = 21% = 0.21 (Probability of playing varsity sports)

We need to find PA(|B), which represents the probability of playing varsity sports given that the teenager plays a team sport.

The conditional probability formula is:

P(A|B) = P(A ∩ B) / P(B)

P(A ∩ B) represents the probability of both A and B occurring simultaneously.

In this case, the probability of a teenager playing varsity sports and a team sport simultaneously is not given directly. However, we can make an assumption that all teenagers who play varsity sports also play a team sport. Under this assumption, we can say that P(A ∩ B) = P(A) = 0.21.

Now we can calculate P(A|B):

P(A|B) = P(A ∩ B) / P(B)

       = 0.21 / 0.43

      ≈ 0.4884

Therefore, the probability that a teenager plays varsity sports, given that they play a team sport, is approximately 0.4884 or 48.84%.

The classification of the system of linear equations 4x + y = 4 and y = -4x + 4 is: consistent and independent. The Option B is correct.

We have a consistent independent equation when a system of linear equations has exactly one solution. When this occurs, the graphs of the system's lines cross at exactly one point.

For our question, we can start by rearranging the first equation to isolate y:

\(4x + y = 4\\y = -4x + 4\)

We can see that the second equation is already in the form y = mx + b, where m is the slope and b is the y-intercept. So we can identify that the slope of the second equation is -4 and the y-intercept is 4.

Now we can compare the slopes and y-intercepts of the two equations to determine the classification of the system of equations:

In this case, we can see that the slopes of the two equations are different (-4 and 0) and the y-intercepts are the same (4). Therefore, the system is consistent and there is a unique solution. So the classification of the system of linear equations 4x + y = 4 and y = -4x + 4 is: consistent and independent

Carol will need to drive at a speed of approximately 63.4 miles per hour to arrive at the park-and-ride at the same time as Irving.

To find out how fast Carol needs to drive, we need to calculate the distance each person travels and then divide it by the time they spend driving.

First, let's calculate the distance Irving travels. He drives along Highway 42, which is a straight line, and his destination is 119 miles east and 19 miles north of Appletown. Using the Pythagorean theorem, we can find the straight-line distance as follows:

Distance = √(119^2 + 19^2) = √(14161 + 361) = √14522 ≈ 120.4 miles

Next, we calculate the time it takes for Irving to reach the park-and-ride by dividing the distance by his speed:

Time = Distance / Speed = 120.4 miles / 45 mph ≈ 2.67 hours

Now, let's calculate the distance Carol travels. She starts from Coconutville, which is 76 miles east and 49 miles south of Appletown. To reach the park-and-ride, she needs to travel north along Highway 86 and then join Highway 42. This forms a right-angled triangle. We can find the distance Carol travels using the Pythagorean theorem:

Distance = √(76^2 + 49^2) = √(5776 + 2401) = √8177 ≈ 90.4 miles

Since Carol leaves at 9 am and Irving leaves at 7 am, Carol has 2 hours less time to reach the park-and-ride. Therefore, we need to calculate Carol's required speed to cover the distance in this shorter time:

Speed = Distance / Time = 90.4 miles / 2 hours = 45.2 mph

To arrive at the park-and-ride at the same time as Irving, Carol will need to drive at a speed of approximately 63.4 miles per hour.
