Step-by-step explanation:

After 3 months there's $150, and after 6 months there's 300. When averaged out (150/3 and 300/6), both equal 50, meaning the constant rate of change is $50 a month.

Answer: The length of AC to one decimal place in the trapezium is 18.1 cm

Step-by-step explanation: Using Pythagoras theorem, we can find the length AC

Pythagoras theorem

c² = a² + b²

Therefore, draw a line from the point B to the line AD and call it line BX.

BX ║ CD

Therefore,

16² - 7² = BX²

256  - 49 = BX²

BX² = 207

BX = √207

BX = 14.3874945699

BX = 14.4 cm

Therefore,

11² + 14.4² = AC²

121 + 207.36 = AC²

AC = √328.36

AC = 18.120706388

AC = 18.1 cm

Step-by-step explanation:

The t-value is often used instead of the z-value in statistical tests because the assumptions of the z-value are violated when the sample size is 30 or less.

The t-value is preferred over the z-value in certain scenarios due to the violation of assumptions associated with the z-value when the sample size is small (30 or less). The z-value assumes that the population standard deviation is known, which is often not the case in practice. In situations where the population standard deviation is unknown, the t-value is used because it relies on the sample standard deviation instead. By using the t-value, we account for the uncertainty associated with estimating the population standard deviation from the sample.

Additionally, the t-value is easier to calculate and interpret compared to the z-value. The t-distribution has a wider range of degrees of freedom, allowing for more flexibility in analyzing data. Moreover, the t-value is more widely known among statisticians and is readily available in statistical software packages, making it a convenient choice for conducting hypothesis tests and confidence intervals.

Overall, the t-value is preferred over the z-value when the assumptions of the z-value are violated or when the population standard deviation is unknown.

The perimeter of the isosceles triangle will be P(x) = x√2 + 2x.

A polygon with three sides is known as a triangle. The angles of a triangle add up to form 180° and the sum of all sides of a triangle is known as the perimeter. In an isosceles triangle, the two sides are equal and their opposite angle too. In an isosceles triangle, the hypotenuse side of the triangle can be written as h(x) = x√2. The combined length comes out to be  L(x) = 2x. Using this information the perimeter of the triangle comes out to be,

P(x) = h(x) + L(x).

P(x) =  x√2 + 2x

Hence the perimeter of the triangle comes out to be P(x) =  x√2 + 2x

If we pay 12.5 percent for 10 years, our monthly payment for a $6000 loan will be about (C) $55.58.

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it.

A % is a number that has neither dimensions nor a defined unit of measurement.

To calculate the percentage, we must divide the value by the entire amount and then multiply the result by 100.

So, if the interest rate is 12.5%, our total loan payment would be:

112.5/100 × 6,000 = $6,750.

The monthly payment would be if there was no buildup and other agreement in payment:

6750/12*10

6750/120

$56.25

Therefore, if we pay 12.5% for 10 years, our monthly payment for a $6000 loan will be about (C) $55.58.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The explanation is attached below.

The linear relationship between time and distance can be considered proportional. The constant of proportionality in this case is 4.

In a proportional relationship, the ratio between the two quantities remains constant. Here, as time increases by 2 hours, the distance also increases by 8 miles. Let's calculate the ratio of distance to time for each pair of values:

For the first pair (2 hours, 8 miles):

Ratio = distance / time = 8 miles / 2 hours = 4 miles/hour

For the second pair (4 hours, 16 miles):

Ratio = distance / time = 16 miles / 4 hours = 4 miles/hour

For the third pair (6 hours, 24 miles):

Ratio = distance / time = 24 miles / 6 hours = 4 miles/hour

For the fourth pair (8 hours, 32 miles):

Ratio = distance / time = 32 miles / 8 hours = 4 miles/hour

As we can see, the ratio of distance to time remains constant at 4 miles per hour for all the pairs. This indicates a proportional relationship between time and distance.

Therefore, the linear relationship is also proportional, and the constant of proportionality is 4.

Because 45 is the largest number.

ఊhe directional derivative of f at the point (1, 2, 2) in the direction of the vector v = (1/5√2)i + (1/5√2)j is 2√2.

To find the directional derivative of the function f(x, y, z) = 2z^2x + y^3 at the point (1, 2, 2) in the direction of the vector v = (1/5√2)i + (1/5√2)j, we can use the formula for the directional derivative:

D_v(f) = ∇f · v

where ∇f is the gradient of f.

Taking the partial derivatives of f with respect to each variable, we have:

∂f/∂x = 2z^2

∂f/∂y = 3y^2

∂f/∂z = 4xz

Evaluating these partial derivatives at the point (1, 2, 2), we get:

∂f/∂x = 2(2)^2 = 8

∂f/∂y = 3(2)^2 = 12

∂f/∂z = 4(1)(2) = 8

Therefore, the gradient ∇f at (1, 2, 2) is given by ∇f = 8i + 12j + 8k.

Substituting the values into the directional derivative formula, we have:

D_v(f) = ∇f · v = (8i + 12j + 8k) · (1/5√2)i + (1/5√2)j

= 8(1/5√2) + 12(1/5√2) + 8(0)

= (8/5√2) + (12/5√2)

= (8 + 12)/(5√2)

= 20/(5√2)

= 4/√2

= 4√2/2

= 2√2

Hence, the directional derivative of f at the point (1, 2, 2) in the direction of the vector v = (1/5√2)i + (1/5√2)j is 2√2.

Therefore, the equation for the ellipse is: 16x^2 + 12.25y^2 = 16.

To find the equation for an ellipse with its center at the origin, a horizontal major axis of length 8, and a minor axis of length 7, we can use the standard form of the equation for an ellipse:

(x^2 / a^2) + (y^2 / b^2) = 1

Where 'a' represents the semi-major axis and 'b' represents the semi-minor axis.

In this case, since the major axis is horizontal and has a length of 8, the value of 'a' is half of the major axis length, which is 8/2 = 4.

Similarly, the value of 'b' is half of the minor axis length, which is 7/2 = 3.5.

Plugging these values into the equation, we get:

(x^2 / 4^2) + (y^2 / 3.5^2) = 1

Simplifying, we have:

(x^2 / 16) + (y^2 / 12.25) = 1

Answer: D, 36in.

Step-by-step explanation:

The height of the monster on the 40-inch TV screen will be 8 inches, which is larger than its height on Hunter's tablet.

First, we need to find out the scale of the monster on Hunter's tablet, which can be calculated as follows

Screen aspect ratio = 8/6 = 4/3

Height of monster on tablet = 5 inches

Width of monster on tablet = (4/3) x 5 = 6.67 inches (because the aspect ratio is 4:3, the width of the monster is 4/3 times its height)

Next, we need to find out the height of the monster on the 40-inch TV screen, which has the same 4:3 aspect ratio as the tablet screen. We can do this by using a proportion

Tablet screen height, Tablet screen width = TV screen height : TV screen width

Substituting the values we know, we get,

6 inches : 8 inches = TV screen height : 10.67 inches (because 40 inches is 4/3 times the width of the TV screen)

Solving for TV screen height, we get,

TV screen height = (6/8) x 10.67 = 8 inches

Answer:

x - 2y + 1 = 0

Step-by-step explanation:

Given

y - 2 = \(\frac{1}{2}\) (x - 3) ← multiply through by 2 to clear the fraction

2y - 4 = x - 3 ( subtract 2y from both sides )

- 4 = x - 2y - 3 ( add 4 to both sides )

0 = x - 2y + 1, that is

x - 2y + 1 = 0 ← in general form

The angle between the vectors can be found using the dot product. The formula is θ= |A| =√(x12 + y12 + z12) The angle between the vectors -2i + 3j + k and i + 2j - 4k is approximately 137.8 degrees.

v1 • v2 = (-2i + 3j + k) • (i + 2j - 4k)

= -2 - 6 + 1 = -7

|v1| = \(\sqrt{((-2)^2 + 3^2 + 1^2)}\)

=\(\sqrt{(4 + 9 + 1)}\)

=\(\sqrt{14}\)

|v2| = \(\sqrt{((1)^2 + 2^2 + (-4)^2)}\)

= \(\sqrt{(1 + 4 + 16) }\)

= (\(\sqrt{21}\)

θ= |A| (-7/\(\sqrt{14}\)\(\sqrt{21}\))

=  |A| (-7/21*14)

=  |A|(-7/294)

= 137.8 degrees

The angle between two vectors can be found using the dot product formula. This formula isθ= |A| =√(x12 + y12 + z12). In the case of the vectors -2i + 3j + k and i + 2j - 4k, this formula can be used to find the angle between them. The dot product of the two vectors is -2 - 6 + 1 = -7. The magnitude of the first vector, |v1|, can be found using the Pythagorean theorem, which is

\(\sqrt{((-2)^2 + 3^2 + 1^2)}\)

= \(\sqrt{(4 + 9 + 1)}\)

= \(\sqrt{14}\).

The magnitude of the second vector, |v2|, can be found using the Pythagorean theorem, which is

\(\sqrt{((1)^2 + 2^2 + (-4)^2)}\)

= \(\sqrt{(1 + 4 + 16)}\)

= \(\sqrt{21}\)

Once the dot product and magnitudes are known, the angle between the two vectors can be found using the formula .Therefore, the angle between the two vectors is approximately 137.8 degrees.

a) The estimated sales (in $1000) decrease by $8.

b) The point estimate for sales (in dollars) when the advertising expenditure is $10,000 is $40,500.

a) The estimated slope coefficient for price in the regression equation ŷ = 60 - 8x is -8. This means that for every one-unit increase in price, the estimated sales (in $1000) decrease by $8. In other words, the regression suggests that there is a negative relationship between price and sales, where higher prices are associated with lower sales.

b) In the regression equation ŷ = 500 + 4x, the coefficient of the advertising variable is 4. If the advertising expenditure is $10,000 (which can be written as 100 × 100), we can substitute this value into the regression equation:

ŷ = 500 + 4(100 × 100)

ŷ = 500 + 4(10,000)

ŷ = 500 + 40,000

ŷ = 40,500

Therefore, the point estimate for sales (in dollars) when the advertising expenditure is $10,000 is $40,500.
