Using algebra, we can conclude that, if Jamie only works 10 hours during the week, he will not be able to meet his goal of earning at least $279, because the total pay he will earn, which is $232.50, is less than the amount he wants to earn.

The method to use to solve this problem would be algebra. We will use variables to represent the number of hours that Jamie works during the week and on the weekend, and we used equations to express the relationship between the total pay Jamie earns and the number of hours he works.

Let's first find out how many hours Jamie works during the week and on the weekend.

Let's say Jamie works x hours during the week. Then, he works 2x hours on the weekend.

The total amount of money Jamie earns is given by:

Total pay = Pay for week hours + Pay for weekend hours

Pay for week hours = $7.75 per hour * x hours

Pay for weekend hours = $7.75 per hour * 2x hours = $15.50 per hour * x hours

Total pay = $7.75x + $15.50x = $23.25x

Now let's substitute x = 10, since Jamie wants to work 10 hours during the week, to see if he can meet his goal of earning at least $279:

Total pay = $23.25 * 10 = $232.50

Since $232.50 is less than $279, Jamie will not meet his goal by working 10 hours during the week alone. He will need to work more hours during the week and/or on the weekend to reach his goal.

Lesley has 5/9 of the counters that Adam initially had.

An element of a number or any number of equal parts is represented by a fraction. There is a fraction with an upper value (numerator) and a lower value (denominator) (lower value).

Ten of the 18 counters that Adam had were given to Lesley. Lesley currently possesses 10 counters.

We must divide Lesley's total number of counters by Adam's starting total number of counters in order to determine the proportion of the 18 counters that Lesley has:

Lesley has 10/18 counters, which is her percentage.

By dividing the numerator and denominator by their 2 greatest common factor, we may simplify this fraction:

Lesley has a fraction of the counters she needs: (10 ÷ 2) / (18 ÷ 2) = 5/9

The result of sin (A - B) is 21/221.

To evaluate sin (A - B), we can use the formula:

sin (A - B) = sin A * cos B - cos A * sin B.

We are given that sin A = 12/13 and cos B = 8/17. We need to find cos A and sin B to use the formula.

Since A is in Quadrant II, cos A is negative. We can use the Pythagorean identity, sin²A + cos²A = 1, to find cos A:

cos²A = 1 - sin²A
cos²A = 1 - (12/13)²
cos²A = 1 - 144/169
cos²A = 25/169
cosA = -5/13

Similarly, since B is in Quadrant IV, sin B is negative. We can use the Pythagorean identity to find sin B:

sin²B = 1 - cos²B
sin²B = 1 - (8/17)²
sin²B = 1 - 64/289
sin²B = 225/289
sinB = -15/17

Now we can plug in the values into the formula:

sin (A-B) = (12/13)*(8/17) - (-5/13)*(-15/17)
sin (A-B) = 96/221 - 75/221

Answer:

∠BCA 57 degrees

Step-by-step explanation:

∠ABC + (5x + 12) = 180

=> ∠ABC = 180 - (5x + 12)

∠BAC + (9x + 1) = 180

=> ∠BAC = 180 - (9x + 1)

∠BCA + (10x - 37) = 180

=> ∠BCA = 180 - (10x - 37)

∠ABC + ∠BAC + ∠BCA = 180

Substitute to find x

[180 - (5x + 12)] + [180 - (9x + 1)] + [180 - (10x - 37)] = 180

180 + 180 + 180 - 5x - 9x - 10x - 12 - 1 + 37 = 180

564 - 24x = 180

24x = 564 - 180

24x = 384

x = 384/24 = 16

Substitue x = 16

∠BCA = 180 - (10x - 37)

∠BCA = 180 - 10(16) + 37 = 57

Answer:

m∠BCA = 57°

Step-by-step explanation:

To find the measure of angle BCA we must first find the value of x.

The diagram gives expressions for the exterior angles of the triangle.

The exterior angles of a triangle sum to 360°. Therefore, to calculate the value of x, equate the sum of the exterior angles to 360° and solve for x.

⇒ (9x + 1)° + (5x + 12)° + (10x - 37)° = 360°

⇒ 9x + 1 + 5x + 12 + 10x - 37 = 360

⇒ 9x + 5x + 10x + 1 + 12 - 37 = 360

⇒ 24x - 24 = 360

⇒ 24x - 24 + 24 = 360 + 24

⇒ 24x = 384

⇒ 24x ÷ 24 = 384 ÷ 24

⇒ x = 16

Each interior and exterior angle of a triangle form a linear pair.

As the sum of angles of a linear pair is always equal to 180°, to find the measure of angle BCA, equate the sum of ∠BCA and its exterior angle to 180°:

⇒ (10x - 37)° + m∠BCA = 180°

Substitute the found value of x and solve for the angle:

⇒ (10(16) - 37)° + m∠BCA = 180°

⇒ (160 - 37)° + m∠BCA = 180°

⇒ 123° + m∠BCA = 180°

⇒ 123° + m∠BCA - 123° = 180° - 123°

⇒ m∠BCA = 57°

Therefore, the measure of angle BCA is 57°.

angle 1 will be 32

y = -2x + 14

To reflect the equation y = 4 across the y-axis, we need to change the sign of the x-term. Since there is no x-term in the original equation, we can simply add a negative x-term to get the reflected equation: y = -x + 4.

Next, to translate the equation to the right 3 units, we need to subtract 3 from the x-term. This gives us the translated equation: y = -(x - 3) + 4.

Finally, to vertically stretch the equation by a factor of 2, we need to multiply the entire equation by 2. This gives us the final transformed equation: y = 2(-x + 3) + 8.

In summary, the equation y = 4 reflected across the y-axis, translated to the right 3 units, and vertically stretched by a factor of 2 is y = -2x + 14.

The eigen values of the matrix A are 2, -2, and 7, and the corresponding eigen vectors are [1,1,2], [1,-2,0], and [2,1,1].

To find the eigen values and eigen vectors of the matrix A=([2,2,0],[2,1,1],[-7,2,-3]), we first need to find the characteristic equation of the matrix. This is done by finding the determinant of (A-λI), where λ is the eigenvalue and I is the identity matrix.

The characteristic equation is:
|A-λI| = |[2-λ,2,0],[2,1-λ,1],[-7,2,-3-λ]| = 0

Expanding the determinant, we get:
(2-λ)((1-λ)(-3-λ)-2) - 2(2(-3-λ)+7) + 0 = 0

Simplifying the equation, we get:
-λ³ + 6λ² - 5λ - 14 = 0

The eigen values are the roots of this equation. We can use the rational root theorem to find the possible rational roots of the equation, which are ±1, ±2, ±7, and ±14. By testing these values, we find that the eigen values are λ=2, λ=-2, and λ=7.

Now, we can find the eigen vectors by plugging the eigen values back into the equation (A-λI)v=0, where v is the eigen vector.

For λ=2, we get:
([2-2,2,0],[2,1-2,1],[-7,2,-3-2])v = 0
([0,2,0],[2,-1,1],[-7,2,-5])v = 0

The eigen vector for λ=2 is v = [1,1,2].

For λ=-2, we get:
([2+2,2,0],[2,1+2,1],[-7,2,-3+2])v = 0
([4,2,0],[2,3,1],[-7,2,-1])v = 0

The eigen vector for λ=-2 is v = [1,-2,0].

For λ=7, we get:
([2-7,2,0],[2,1-7,1],[-7,2,-3-7])v = 0
([-5,2,0],[2,-6,1],[-7,2,-10])v = 0

The constant of proportionality for the Amador family is obtained as k = 7.50.

The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.

If the cost t varies directly with the number of thousand cubic feet of natural gas g used, we can write -

t = kg

where k is the constant of proportionality, which represents the cost per thousand cubic feet of natural gas.

Since the Amador family pays $7.50 per thousand cubic feet of natural gas, we have -

k = 7.50

Therefore, the equation relating the total cost t to the number of thousand cubic feet of natural gas g used is -

t = 7.50g

This means that for every thousand cubic feet of natural gas used, the cost is $7.50.

If the Amador family uses 10,000 cubic feet of natural gas, the total cost would be -

t = 7.50(10) = $75

If they use 20,000 cubic feet of natural gas, the total cost would be -

t = 7.50(20) = $150

Therefore, the COP value is k = 7.50.

The distance between the stop signs is 0.375 miles or roughly 0.6 kilometers.

distance between stop signs = 3 miles / 8

= 0.375 miles

While distance and displacement appear to have the same meaning, they actually have very different definitions and implications. Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."

Distance is the sum of an object's movements, regardless of direction. The distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

The scalar quantity known as distance measures "how much ground an object has traversed" while moving.

From the question:

We can use the following calculation to calculate the separation between the stop signs:

distance between stop signs = total distance/number of intervals

There are 8 spaces between the stop signs and a total distance of 3 miles in this instance. As a result, we can determine the separation between the stop signs as:

distance between stop signs = 3 miles / 8

= 0.375 miles

As a result, there are 0.375 miles (or 0.6 kilometers) between each stop sign.

Starting with a $500 investment, you would have approximately $6,795.70 after 40 years if the investment increases exponentially by about 15% every 2 years.

Algebraic expression can be defined as combination of variables and constants.

To find the future amount of the investment after 40 years, we can use the formula for compound interest:

Future Amount = Present Value x (1 + Interest Rate/Compounding Frequency)^(Compounding Frequency x Time)

In this case, the present value (PV) is $500, the interest rate (r) is 15%,

the compounding frequency (n) is 1 (since the interest is compounded every 2 years).

The time (t) is 40 years.

Plugging in the values, we get:

Future Amount = [tex]500 \times (1 + 0.15/1)^{(1 \times 40/2)}[/tex]

Future Amount = [tex]500 \times (1.15)^{20}[/tex]
