Answer:

Option B is the correct answer.

Step-by-step explanation:

\(f(x)=27\bigg(\frac{1}{3}\bigg)^x\) matches the table.

• When x = 0

\(\implies f(x)=27\bigg(\frac{1}{3}\bigg)^0= 27*1=27\)

•When x = 1

\(\implies f(x)=27\bigg(\frac{1}{3}\bigg)^1= 27*\frac{1}{3}=9\)

•When x = 2

\(\implies f(x)=27\bigg(\frac{1}{3}\bigg)^2= 27*\frac{1}{9}=3\)

•When x = 3

\(\implies f(x)=27\bigg(\frac{1}{3}\bigg)^3= 27*\frac{1}{27}=1\)

•When x = 4

\(\implies f(x)=27\bigg(\frac{1}{3}\bigg)^4= 27*\frac{1}{81}=\frac{1}{3}\)

Answer:

i) x = 0.25 and 1.25

ii) x = -0.5 and 1.5

Step-by-step explanation:

Given that y = 4x² - 4x - 1. So for question 1, you can let y = 0, then see which x-value did the curve touches 0 at y-axis.

Same for question 2.

The northerly component of the wind blowing at 15 m/s from the South East is approximately 10.605 m/s.

To determine the northerly component of a wind blowing from the South East, we need to consider the direction from which the wind is coming and its magnitude.

A wind blowing from the South East means it is coming from the South East direction towards the opposite direction, which is the North West. Since the wind is coming from the South East, we can say it has a southeasterly direction.

To find the northerly component, we need to break down the wind vector into its north and east components. The northerly component represents the part of the wind that is directed towards the north.

If we assume that the wind is blowing at an angle of 45 degrees with respect to the North, we can use trigonometry to find the components. Since the wind is blowing at 15 m/s, we can consider it as the hypotenuse of a right triangle.

The northerly component can be found using the sine of the angle:

Northerly Component = Wind Speed * sin(Angle)

Northerly Component = 15 m/s * sin(45°)

Using the value of sin(45°) (which is √2 / 2 ≈ 0.707), we can calculate the northerly component:

Northerly Component ≈ 15 m/s * 0.707

Northerly Component ≈ 10.605 m/s

Answer:

anta did not add 12 to both sides correctly

Step-by-step explanation:

because -34 +12=22

Answer:

C. Anita did not add 12 to both sides correctly

Step-by-step explanation:

when moving a number to the other side of the equal sign, the sign of the number changes

originally 12 is negative 12 because of the subtraction sign. when flipped over the equal sign, it turns into a positive.

so instead of -34-12

it would be -34+12

Answer:

\(y=-\frac{4}{3} x-\frac{14}{3}\)

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form:

\(y=mx+b\) where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

Parallel lines will always have the same slope. Therefore, this line will have the same slope as the given line \(y=-\frac{4}{3} x+ \frac{7}{3}\).

Plug in \(-\frac{4}{3}\) as the slope

\(y=-\frac{4}{3} x+b\)

2) Determine the y-intercept (b)

To find the y-intercept, plug the given point (-5,2) into the equation and solve for b.

\(2=-\frac{4}{3}(-5)+b\\2=\frac{20}{3}+b\)

Subtract both sides by \(\frac{20}{3}\)

\(2-\frac{20}{3} = \frac{20}{3}+b-\frac{20}{3}\\\frac{6}{3} -\frac{20}{3}=b\\-\frac{14}{3} = b\)

Therefore, the y-intercept is \(-\frac{14}{3}\).

3) Plug the y-intercept back into our original equation

\(y=-\frac{4}{3} x-\frac{14}{3}\)

Answer:

56 mins

Step-by-step explanation:

Number of gallons of water in the pool per minute;

750 divided by 35 = 150/7

Let the time needed to fill a 1,200 gallon pool be t.

t x 150/7 = 1,200

t x 21.42857142857143... = 1,200

t = 1,200/21.42857142857143

t = 56 mins

The value of \(f\) is \(0\), by using the concept of slope of a line.

The equation to find the slope of a line is given by:

\(\(\text{slope} = \frac{{y_2 - y_1}}{{x_2 - x_1}}\)\)

Given that the slope is -8 and the points (-7, f) and (-6, -8) lie on the line, we can substitute the coordinates into the equation:

\(\(-8 = \frac{{-8 - f}}{{-6 - (-7)}}\)\)

Simplifying the equation:

\(\(-8 = \frac{{-8 - f}}{{1}}\)\)

Multiply both sides by 1:

\(\(-8 = -8 - f\)\)

Rearranging the equation:

\(\(-8 + 8 = -f\)\(0 = -f\)\)

The concept used in this problem is finding the slope of a line using two given points. The slope represents the rate of change of the line, indicating how much the line rises or falls for each unit of horizontal distance.

By substituting the coordinates of the two given points (-7, f) and (-6, -8) into the formula, we can calculate the slope.

Thus, the value of \(f\) is \(0\).

As a result, the distance between Sally's house and the restaurant is shorter than that between Ben's house and it. 250 miles minus 100 miles equals 150 miles. The response is D. 150 miles.

Distance is still a unit used to define how far apart two places or objects are from one another. It is a score that expresses the separation that two things or places are from one another. In mathematics, the separation between two objects is typically calculated using a metric or range function, which gives the distance a numerical value. The most typical euclidean distance is the Distance measure, which calculates the separation of two points in a 2- or 3 space along a straight line. The concept of distance is crucial to many mathematical fields, physics, and architecture.
