(Refer to both images for all answers)

Answer:

34

Step-by-step explanation:

The value of the function f(x) = g(x) is [tex]x^2 -8x + 15 = 0[/tex]

Data;

Solving the function above by substitution method, we just need to substitute the values where required and solve.

[tex]f(x) = g(x)[/tex]

Substituting the value,

[tex]x^2 - 7x + 13 = x - 2\\x^2 -7x - x + 13 + 2 = 0\\x^2 -8x + 15 = 0[/tex]

The value of the function f(x) = g(x) is [tex]x^2 -8x + 15 = 0[/tex]

Answer:

The correct option is;

R0, 180°

Step-by-step explanation:

The coordinates of ΔXYZ are given as follows;

X(-2, 2), Y(1, 2), Z(0, 4)

The coordinates of ΔX'Y'Z' are given as follows;

X'(2, -2), Y'(-1, -1), Z'(0, -4)

Whereby, the coordinates of the point Y' is (-1, -2), we have the rule that describe the transformation of ΔXYZ to ΔX'Y'Z', given as follows

Coordinates of the preimage = (x, y)

Coordinates of the image = (-x, -y)

Which is in accordance with the transformation by rotation 180° about the origin.

Answer:

Option (2)

Step-by-step explanation:

From the given set of numbers we have to arrange them in the increasing order.

{[tex]\sqrt{72},9.25,\sqrt{83},\pi^2,8.7[/tex]}

Since, [tex]\sqrt{72}=8.49[/tex]

[tex]\sqrt{83}=9.11[/tex]

[tex]\pi ^2[/tex] = 9.87

Therefore, set of numbers will be in the form of,

{8.49, 9.25, 9.11, 9.87, 8.7}

Now arranging these numbers in the increasing order,

8.49 < 8.7 < 9.11 < 9.25 < 9.87

Therefore, numbers in the increasing order will be,

{[tex]\sqrt{72},8.7,\sqrt{83},9.25,\pi ^{2}[/tex]}

The distance of Saturn from the sun is 9.5 astronomical units.

Orbital period p of a planet and the planet’s distance from the sun, a in astronomical units are related by:

[tex]p = a^{3/2}[/tex]

The orbital period is the time a given astronomical object takes to complete one orbit around the sun.

Given that Saturn's orbital period is 29.5 years.

So, [tex]29.5 = a^{3/2}[/tex]

[tex]a = 29.5^{2/3}[/tex]

a = 9.5 au

Therefore, the distance of Saturn from the sun is 9.5 astronomical units.

The key used is "Evenly"

Step-by-step explanation:

Lisa owes $500 for a car payment.

Her mother and sister would be willing to split the car payment Evenly and pay it for her.

So, they each pay towards the payment = [tex]\frac{500}{2}[/tex] =250

So, each pay $250.

Question: jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar

Find: how much money she has in her coin jar

Solution: let's make an equation for this problem

She has 4 more dimes than nikels:y= x+4 Let's use this value for y in the next equation:

she has 18 nickels and 36-18= 18 dimes

The required Jasmine has 16 nickles and 20 dimes which constitute  $2.80 in her coin jar.

Let's use the given information to set up a system of equations to solve for the number of nickels (x) and dimes (y) in Jasmine's coin jar.

We are given that Jasmine has a total of 36 coins in her jar, so we have the equation:

x + y = 36 -- Equation 1

We are also given that Jasmine has four more dimes than nickels, which can be expressed as:

y = x + 4 -- Equation 2

Now, let's solve this system of equations. We can substitute Equation 2 into Equation 1 to eliminate y:

x + (x + 4) = 36

2x = 36 - 4

x = 16

Now that we have the value of x, we can substitute it back into Equation 2 to find y:

y = x + 4

y = 16 + 4

y = 20

Therefore, Jasmine has 16 nickels (x) and 20 dimes (y) in her coin jar.

To find the total amount of money she has, we need to calculate the value of the nickels and dimes separately:

Value of nickels = 0.05 * 16 = $0.80

Value of dimes = 0.10 * 20 = $2.00

The total amount of money in her coin jar is:

$0.80 + $2.00 = $2.80

Jasmine has $2.80 in her coin jar.

Step-by-step explanation:

Given the following question:

[tex]\frac{2}{3} y=\frac{1}{4}[/tex]

To find the answer we need to isolate the variable, in order to do that we need to use inverse of operations on this problem.

[tex]\frac{2}{3} y=\frac{1}{4}[/tex]
[tex]3\times\frac{2}{3} =2[/tex]
[tex]\frac{1\times3}{4} =\frac{3}{4}[/tex]

We know that revenue= production=break even point

given that the expression for cost of production is

z=120+4x---------------1 cost of production

where x is the number of items produced

also the selling price per item is $5

The revenue generated from the production of x items is(let the revenue be y)

y=5x------------2 revenue equation

break-even is when y=z

120+4x=5x

solving for x we have

120=5x-4x

120=x

x=120items
