Solve the System of these Equations

Answer:

[tex]f^{-1}[/tex] (59) = 20

Step-by-step explanation:

[tex]f^{-1}[/tex] (x) is the inverse of f(x)

to find the inverse function, let f(x) = y and rearrange to make x the subject.

y = 3x - 1 ( add 1 to both sides )

y + 1 = 3x ( divide both sides by 3 )

[tex]\frac{y+1}{3}[/tex] = x

change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then

[tex]f^{-1}[/tex] (x) = [tex]\frac{x+1}{3}[/tex] , then

[tex]f^{-1}[/tex] (59) = [tex]\frac{59+1}{3}[/tex] = [tex]\frac{60}{3}[/tex] = 20

System of equation consists of two or more equations with unknow variables. A possible step used in eliminating the y-term is (y + z  6) *5

System of equation consists of two or more equatons with unknow variables.

Given the system of equations

y + z = 6

5y + 9z =1

In order to eliminate the variable "y", we will multiply equation 1 by 5 and subtract from equation 2;

5y + 5z = 30

5y + 9z = 1

Subtract

5z - 9z = 30 - 1

-4z =29

This leaves only the variable "z" eliminating variable. "y"

2)  32.2 in (nearest tenth)

Step-by-step explanation:

Pythagoras’ Theorem

[tex]\sf a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

Substituting these values into the formula and solving for c:

[tex]\implies \sf 16^2+28^2=c^2[/tex]

[tex]\implies \sf 256+784=c^2[/tex]

[tex]\implies \sf c^2=1040[/tex]

[tex]\implies \sf c=\pm\sqrt{1040}[/tex]

[tex]\implies \sf c=\pm 32.2\:in\:(nearest\:tenth)[/tex]

As distance is positive, c = 32.2 in (nearest tenth)

Step-by-step explanation :

Here, A right angled triangle is given with the measure of two sides and we are to find the measure of the third side.

We'll find the measure of third side with the help of the Pythagorean theorem,

[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}} \\ \\ [/tex]

Here,

The exponential function is given by f(x) = 2ˣ and the  value of f(6) is 64

An equation is an expression that shows the relationship  between two or more numbers and variables.

An exponential funtion is in the form y = abˣ

At point (0, 1):

1 = ab⁰

a = 1

At point (2, 4):

4 = 1(b)²

b = 2

Hence:

f(x) = 2ˣ

Hence f(6):

f(6) = 2⁶ = 64

The exponential function is given by f(x) = 2ˣ and the  value of f(6) is 64

The minimum number of calories the group is expected to consume during the entire trip from current location to southpole and back to camp is 375 kilo calories.

Pythagoras theorem says that in a right angle triangle the square of hypotenuse side is equal to the sum of square of other two legs of right angle triangle.

There are total 5 miles in one block and current location to the South Pole there are 5 blocks on map. Thus, the total distance from current location to the South Pole is,

[tex]x=5\times5\\x=25\rm\; miles[/tex]

There are total 12 blocks from current location to the camp on map. Thus, the total distance from current location to the camp is,

[tex]y=12\times5\\y=60\rm\; miles[/tex]

The shortest distance from South Pole to camp is,

[tex]z=\sqrt{25^2+60^2}\\z=\sqrt{4225}\\z=65\rm\; miles[/tex]

Total distance group travel from if it wants to travel from its current location on the map to the South Pole, and then directly back to base camp, passing through their current location is,

[tex]n=65+60\\n=125\rm\; miles[/tex]

The group travel an average of 10 miles per day. Thus, number of days to cover distance,

[tex]\dfrac{125}{10}=12.5\rm\; days[/tex]

There are total 5 people in group and they consume each person needs 6000 calories per day. Thus, total calories,

[tex]C=12.5\times6000\times5\\C=375000 \rm\;C\\C=375 \rm\; kC[/tex]

Thus, the minimum number of calories the group is expected to consume during the entire trip from current location to southpole and back to camp is 375 kilo calories.

Answer:

1/343    = .00291545

Step-by-step explanation:

= 1/(7*7*7) =

The value of the exponential equation is A = ( 1/343 ) = ( 1/7 )³

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 1/7 ) x ( 1/7 ) x ( 1/7 )   be equation (1)

On simplifying the equation , we get

A = ( 1/7 )³

Now , on further simplification , we get

A = ( 1/343 )

And , the value of A = 0.002915

Hence , the exponential equation is A = ( 1/7)³

Answer:

The time it takes the ball to hit the ground is 3.05secs

step - by - step explanation:

In order to find height from where ball is dropped, you have to find height or h(t) when time or t is zero.So plug in t=0 into your quadratic equation:h(0) = -16.1(0^2) + 150h(0) = 0 +150h(0) = 150 ft is the height from where ball is dropped. When ball hits the ground, the height is zero. So plug in h(t) = 0 and solve for t.0 = -16.1t^2 + 15016.1 t^2 = 150t^2 = 150/16.1t = sqrt(150/16.1)t = ± 3.05Since time cannot be negative, your answer is positive solution i.e. t = 3.05

Answer:

Jacob should work minimum of 14 hours washings cars to meet his requirement.

Step-by-step explanation:

Let the number of hours of washing cars be 'x'.

Let the number of hours of landscaping be 'y'.

Given:

Cost for Per hour for washing cars = $10

Cost for per hour Landscaping = $8

Total number of hours of working

Amount to be earned this weekend

So we can say that;

Also,

Amount to be earned this weekend should be greater than or equal to sum of Cost for Per hour for washing cars multiplied by number of hours of washing cars and Cost for per hour Landscaping multiplied by number of hours of landscaping.

framing in equation form we get;

Now Number of hours he worked for landscaping

So we get;

Subtracting both side by 32 we get;

Dividing both side by 10.

Hence Jacob should work minimum of 14 hours washings cars to meet his requirement.
