The equation representing when the two planes would be at the same altitude is 9x=486

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

From (a) we get that: Altitude of Plane A = 990-18x

Altitude of Plane B = 1476-27x

make 890 - 18x = 1476-27x

-18x+27 x = 1476-890

9x=486

X= 54

so pass 54 seconds will the two plane at the same altitude.

P(A) and P(B) are not independent events.

Event A is said to be independent of event B if the probability of occurrence of one of them is not affected by the occurrence of the other.

 P(A∩B) = P(A)*P(B) for independent events, which is given 0.25 but P(A∩B) = P(A)*P(B) = 0.46*0.57 = 0.26, data does not match.

P(A) = 0.46 and P(B) = 0.57

For A and B to be independent

P (A and B) = 0.46*0.57 = 0.26         [ does not match with given data that is 0.25]

P (A, not B) =0.46*(1-0.57) = 0.19                                                        

P (B, not B) =0.57*(1-0.46) = 0.30

P (not A, not B) = (1-0.46) *(1-0.57) = 0.23

To check if they are independent, sum of all values should be equal to 1

0.57+0.19+0.30+0.23 = 0.98 which is not equal to one.

Therefore P(A) and P(B) are not independent events.

If the total time to travel downstream and return upstream to the starting point is 6 hours. If the total distance downstream and back is 30 miles, the speed of the river (current speed) is 6.

Time = Distance/speed

Time taken to row upstream:

(30/2) /(9 - x)

15/(9-x)

Time taken to row downstream:

15/(9 + x)

Total time spent is 6 hours hence,

15/(9- x) + 15/(9 + x) = 6

Cross multiplying

15(9 + x) + 15(9 - x) = 6(9+ x)(9 - x)

= 135 + 15x + 135- 15x =6(81 -9x + 9x - x²)

=270 = 6(81 - x²)

270/6 = 81- x²

45 = 81- x²

x² = 81- 45

x²= 36

x =√36

The total weight of 4 packets will be equal to 5 and 1 / 2 pounds.

We are given that:

The total number of packages = 4

Weight of each of the package is given as 1 and 3 / 8 pounds

Weight of 1 package = 1 and 3 / 8 pounds.

Weight of 1 package = 11 / 3 pounds

Now, we need to calculate the total weight of 4 packets.

We will do this my multiplying 4 with the weight of each packet.

So, we get that:

Total weight of 4 packets = 4 × 11 / 8 pounds.

Total weight of 4 packets = 11 / 2 pounds

Total weight of 4 packets = 5 and 1 / 2 pounds.

Therefore, the total weight of 4 packets will be equal to 5 and 1 / 2 pounds.

0 steps to reach floor 0.

a.

floor 0 to floor 1 = floor 0 + 14 = 0 + 14 = 14

floor 1 to floor 2 = floor 1 + 14 = 14 + 14 = 28

floor 2 to floor 3 = floor 2 + 14 = 28 + 14 = 42

floor 3 to floor 4 = floor 3 + 14 = 42 + 14 = 56

floor 4 to floor 5 = floor 4 + 14 = 56 + 14 = 70

b.

when we look at the calculation for the stairs to floor 1, then we see

floor 1 = floor 0 + 14 = 0 + 14 = 14

and for floor 2

floor 2 = floor 1 + 14 = floor 0 + 14 + 14 = 0 + 14 + 14 = 28

and for floor 3

floor 3 = floor 2 + 14 = floor 0 + 14 + 14 + 14 = 42

and so on.

we see

floor n = s(n) = s(0) + 14×n = 0 + 14×n = 14n

s(n) = 14n

Answer:

 2 touchdowns, 3 field goals

Step-by-step explanation:

The number of touchdowns cannot be more than 3, so it is relatively easy to find the solution by trial and error.

 23 is not divisible by 3, so 0 touchdowns is not a solution

 23 -7 = 16 is not divisible by 3, so 1 touchdown is not a solution

 23 -14 = 9 is divisible by 3, so 2 touchdowns and 3 field goals is a solution

 21 -21 = 2 is not divisible by 3, so there is only one solution.

Answer:

1 touchdown and 3 field goals

A permutation is an orderly arrangement of the items or numbers. Combinations are a means to choose items or numbers from a collection or set of items without regard for the items' chronological sequence.

We will solve it using permutations and combinations

a. The number is ²⁵P₄=  25! / (25 - 4)!

25! / 21! = 25 × 24 × 23 × 22 = 303600 ways.

b. The number is ²⁵C₄= 25! / 4! . (25 - 4)!

The types of trigonometric identities include;

From the diagram shown, we can see that;

The opposite side of the angle is 2

The hypotenuse side of the angle is 10

The trigonometric identity in this case is sine

sin θ = opposite/ hypotenuse

Substitute the values

sin θ = 2/ 10

sin θ = 0. 2

Step-by-step explanation:

Given function:

[tex]f(x)=x^3+12x^2-27x+11[/tex]

Differentiate the function:

[tex]\implies f'(x)=3 \cdot x^{3-1}+2 \cdot 12x^{2-1}-27x^{1-1}+0[/tex]

[tex]\implies f'(x)=3x^2+24x-27[/tex]

Find the critical points of the function by setting the derivative to zero and solving for x:

[tex]\implies f'(x)=0[/tex]

[tex]\implies 3x^2+24x-27=0[/tex]

[tex]\implies 3(x^2+8x-9)=0[/tex]

[tex]\implies x^2+8x-9=0[/tex]

[tex]\implies x^2+9x-x-9=0[/tex]

[tex]\implies x(x+9)-1(x+9)=0[/tex]

[tex]\implies (x-1)(x+9)=0[/tex]

[tex]\implies x-1=0 \implies x=1[/tex]

[tex]\implies x+9=0 \implies x=-9[/tex]

Therefore, the critical points are x = 1 and x = -9.

Evaluate the function at the endpoints of each interval as well as the critical points if the critical points fall within the given interval.  The largest and smallest values of the function are the absolute extrema.

Part (a)

Given interval = [-10, 0].

One of the critical points is included in the interval.

Evaluate the function at the endpoints and critical point:

[tex]f(-10)=(-10)^3+12(-10)^2-27(-10)+11=481[/tex]

[tex]f(0)=(0)^3+12(0)^2-27(0)+11=11[/tex]

[tex]f(-9)=(-9)^3+12(-9)^2-27(-9)+11=497[/tex]

Therefore:

Part (b)

Given interval = [-7, 2].

One of the critical points is included in the interval.

Evaluate the function at the endpoints and critical point:

[tex]f(-7)=(-7)^3+12(-7)^2-27(-7)+11=445[/tex]

[tex]f(2)=(2)^3+12(2)^2-27(2)+11=13[/tex]

[tex]f(1)=(1)^3+12(1)^2-27(1)+11=-3[/tex]

Therefore:

Part (c)

Given interval = [-10, 2].

Both of the critical points are included in the interval.

Evaluate the function at the endpoints and critical points:

[tex]f(-10)=(-10)^3+12(-10)^2-27(-10)+11=481[/tex]

[tex]f(2)=(2)^3+12(2)^2-27(2)+11=13[/tex]

[tex]f(-9)=(-9)^3+12(-9)^2-27(-9)+11=497[/tex]

[tex]f(1)=(1)^3+12(1)^2-27(1)+11=-3[/tex]

The nth term of the sequence is Tn = 3888^n - 1

From the given sequence, we have that;

a = 648

r = 6
