Answer:

Step-by-step explanation:

To write y as a function of x using the given functions, we can substitute the value of "a" in the first equation with the expression "-5x + 1" from the second equation.

Given:

y = -3a + 3

a = -5x + 1

Substituting the value of "a" in the first equation:

y = -3(-5x + 1) + 3

Now, let's simplify this expression:

y = 15x - 3 + 3

y = 15x

Therefore, y can be expressed as a function of x as:

y = 15x

Karen should buy 93 inches of ribbon.

From the question, we have the following parameters that can be used in our computation:

Bows = 15

Length of bows = 6.2 inches

This means that

Length of ribbon/Number of bows = Length of bows

Substitute the known values in the above equation, so, we have the following representation

Length of ribbon/15 = 6.2

Multiply both sides by 15

Length of ribbon = 93

Hence, the length is 93 inches

Answer:

S(t) = 78000000*e^0.333t

Step-by-step explanation:

Given the following :

Sales in 1992 = $78 million

Sales in 1997 = $412 million

Exponential function that models the sales in millions of dollars as a function of years t since 1992.

S(t) = So*e^kt

S(t) = sales in t years ; So = Initial or starting sales

Find k :

S(t) = sales in 1997 = $412,000,000

So = sales in 1992 = $78,000,000

t = 1997 - 1992 = 5

412,000,000 = 78,000,000 × e^k5

412,000,000 = 78,000,000 × e^5k

412,000,000/ 78,000,000 = e^5k

5.2820512 = e^5k

In(5.2820512) = In(e^5k)

1.6643145 = 5k

k = 1.6643145 / 5

k = 0.3328629

k = 0.333 ( to 3 decimal places)

Hence,

S(t) = 78000000*e^0.333t

Answer:

answer: negative five eighths

The solution to the expression one half cubed − 6 ÷ square root of 64 is A. negative five-eighths.

Given a fractional expression:

One half cubed − 6 ÷ square root of 64

It is required to find the value of the expression.

This can be numerically written as:

\((\frac{1}{2} )^3-6\div\sqrt{64}\)

It is known that:

\(\sqrt{64}=8\)

So, the expression can be written as:

\((\frac{1}{2} )^3-6\div8\)

Now, \((\frac{1}{2} )^3=\frac{1}{2^3}\)

                \(=\frac{1}{8}\)

So, the expression becomes:

\((\frac{1}{8} )-6\div8\)

Using the BODMAS rule, division has to be done first before subtraction.

So, the expression becomes:

\((\frac{1}{8} )-\frac{6}{8}=-\frac{5}{8}\)

Hence, the correct option is A. negative five-eighths.

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42

A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.

The six o'clock position on the Ferris wheel is level with the loading platform.

The wheel completes 1 full revolution in 2 minutes.

We have to find how many minutes of the ride are spent higher than 26 meters above the ground.

So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters

So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)

Also, the height of a person at the lowest point = 4 - 15 = -11 meters

Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.

So, the total distance travelled will be = 19 + 11 = 30 meters.

Also, we are given that the wheel completes 1 full revolution in 2 minutes.

We need to calculate the time spent higher than 26 meters above the ground.

So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.

This angle can be calculated as follows:

Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees

Angle = 30 / (pi * 30) * 360 degrees

Angle = 360 degrees / pi

= 114.59 degrees

So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.

Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.

This can be calculated as follows:

Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken

Time = (180 - 114.59) / 360 * 2 minutes

Time = 0.42 minutes

Answer:

Cost for each pound of jelly beans:  $2.75

Cost for each pound of almonds:  $3.75

Step-by-step explanation:

Let J be the cost of one pound of jelly beans.

Let A be the cost of one pound of almonds.

Using the given information, we can create a system of equations.

Given 3 pounds of jelly beans and 5 pounds of almonds cost $27:

\(\implies 3J + 5A = 27\)

Given 9 pounds of jelly beans and 7 pounds of almonds cost $51:

\(\implies 9J + 7A = 51\)

Therefore, the system of equations is:

\(\begin{cases}3J+5A=27\\9J+7A=51\end{cases}\)

To solve the system of equations, multiply the first equation by 3 to create a third equation:

\(3J \cdot 3+5A \cdot 3=27 \cdot 3\)

\(9J+15A=81\)

Subtract the second equation from the third equation to eliminate the J term.

\(\begin{array}{crcrcl}&9J & + & 15A & = & 81\\\vphantom{\dfrac12}- & (9J & + & 7A & = & 51)\\\cline{2-6}\vphantom{\dfrac12} &&&8A&=&30\end{array}\)

Solve the equation for A by dividing both sides by 8:

\(\dfrac{8A}{8}=\dfrac{30}{8}\)

\(A=3.75\)

Therefore, the cost of one pound of almonds is $3.75.

Now that we know the cost of one pound of almonds, we can substitute this value into one of the original equations to solve for J.

Using the first equation:

\(3J+5(3.75)=27\)

\(3J+18.75=27\)

\(3J+18.75-18/75=27-18.75\)

\(3J=8.25\)

\(\dfrac{3J}{3}=\dfrac{8.25}{3}\)

\(J=2.75\)

Therefore, the cost of one pound of jelly beans is $2.75.

the correct option is D:

" The inverse relation must pass the vertical line test."

Remember that a relation is only a function if each value in the domain is only mapped into a single value in the range.

All functions need to pass what is called the "vertical line test" this means that if you draw a vertical line on the graph of the function, the vertical line can intersect the graph at most one time. If the vertical line intercepts the graph two or more times, then it is not a function.

From this we conclude that the correct option is D:

" The inverse relation must pass the vertical line test."

Taking logs of both sides:

ln (0.3. e^3x) = ln 27

ln (0.3) + ln e^3x = ln 27

ln e^3x = ln 27 - ln(0.3)

We cannot find the lengths of sides a and c or the measure of angle B in this case.

Trigοnοmetry is a branch οf mathematics that deals with the relatiοnships between the sides and angles οf triangles.

We can use the Law οf Sines tο find the lengths οf sides a and c and the measure οf angle B in the triangle given the side length b = 9 and the angle A = 73°. The Law οf Sines states that:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the side lengths of the triangle, and A, B, and C are the angles opposite those sides.

We are given b = 9 and A = 73°. Let's find B first:

a/sin(73°) = 9/sin(B)

sin(B) = (9 sin(73°))/a

B = arcsin((9 sin(73°))/a)

Now, we can find a and c using the Law of Sines:

a/sin(73°) = 9/sin(B)

a = (9 sin(73°))/sin(B)

c/sin(C) = 9/sin(B)

c = (9 sin(C))/sin(B)

Note that we still need to find sin(C) to calculate c. To do this, we use the fact that the sum of angles in a triangle is 180°:

C = 180° - A - B

C = 180° - 73° - B

C = 107° - B

sin(C) = sin(107° - B)

Now we can substitute into the expressions we found for a and c to get:

a = (9 sin(73°))/sin(B)

c = (9 sin(107° - B))/sin(B)

We can solve for B by using the fact that the sum of the angles in a triangle is 180°:

A + B + C = 180°

73° + B + (107° - B) = 180°

B = 180° - 73° - 107°

B = 180° - 180°

B = 0°

This is not a valid solution for B, which means that the triangle cannot exist with the given values of b and A.

Hence, we cannot find the lengths of sides a and c or the measure of angle B in this case.
