does anyone know how to do this

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

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.

The ordered pair  (3, -1) that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are substitute into the inequality 4x - 3y < 16

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

WE have been given an inequality as 4x - 3y < 16.

Here, we need to get the ordered pair solution to the system of linear equations.

Then Substitute x = 3 and y = -1 into 4x - 3y < 16

4(3) - 3(-1) < 16

12 + 3 < 16

15 < 16

(TRUE)

Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair which makes the inequality true.

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.

Step-by-step explanation:

An absolute value expression being multiplied by a negative number will never have a positive y-value output like 24. You can see this when the equation is graphed.

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.

The vertical distance of the jump is 4.8 feet.

We know that the equation that relates the vertical distance of the jump and the time is:

t = √d/2

In this case, we know that the time is t = 1.09 seconds, replacing that in the equation we get:

1.09 = √d/2

Now we can solve that equation for d.

1.09*2 =  √d

Now we apply an exponent of 2 in both sides to remove the square root:

2.18^2 = d = 4.8 ft

weight of empty canteen + ( 32 - x ) of the water x weight of water

This would be represented by

total weight = 0.25 + 0.065 * (32-x)

We have to open up the expression

weight = 0.25 + 2.08 - 0.065x

When the weight is 0 we would have

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]

Therefore:

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

Considering the definition of an inequality, the interval of hours parked for which Garage A is cheaper than Garage B is 6 hours.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

In this case, you know that:

Being "t" the time parked, in hours. If you want to determinate the interval of hours parked for which Garage A is cheaper than Garage B,  the inequality that expresses the previous relationship is

5 + 3t < 11 + 2t
