The dimension that maximize the are of the pen is 45 ft by 90 ft.

where

l = length

w= width

Therefore,

perimeter of a rectangle = 2(l + w)

The barn is occupying one part of the rectangle . Therefore,

perimeter = 2l + w

180 = 2l + w

w  = 180 - 2l

area = lw

Therefore,

area = l(180 - 2l)

area = 180l - 2l²

To maximize area

l = -b / 2a

l = - (180) / 2 × -2

l = -180 / -4

l = 45 ft

Therefore,

w = 180 - 2(45)

w = 180 - 90

w = 90 ft

Simple interest formula:

Total = start x ( 1 + rate x time )

Total = 14,000 x ( 1 + (0.015 x3))

Total = 14,000 x 1.045

Total = 14,630

Answer:

The area of the triangle RST is the amount of space on the triangle RST

The area of the triangle RST is 127135 square cm

The given parameters are:

r = 690 cm, s = 410 cm and ∠T=64°.

Using the sine function, the area of ΔRST is calculated as:

[tex]A = 0.5rs\sin(T)[/tex]

Subsitute known values

A = 0.5 * 690 * 410 * sin(64 degrees)

Evaluate the sine ratio

A = 0.5 * 690 * 410 * 0.8988

Evaluate the product

A = 127135.26

Approximate

A = 127135

Hence, the area of the triangle RST is 127135 square cm

Number of incorrect answers Rashida got = 12

Number of correct answers Rashida got = 18

Given :-

Points for each correct answer =

Points for each incorrect answer =

[tex] = \frac{ - 1}{ \: \: \: 2} [/tex]

Points Rashida will get for her correct answers :-

[tex] = 2 \frac{1}{4} \times 18[/tex]

[tex] = \frac{(4 \times 2+ 1)}{4} \times 18[/tex]

[tex] = \frac{9}{4} \times 18[/tex]

[tex] = \frac{ - 12}{ \: \: \: \: \: 2} [/tex]

[tex] = - 6 \: points[/tex]

So , Rashida gets 40.5 points for her correct answer and -6 points for her incorrect answer .

Rashida's total score :-

[tex] = 40.5 + ( - 6)[/tex]

[tex] = 34.5 \: points[/tex]

Therefore , Rashida gets 34.5 points as her total score .

The overall score of Rashida will be 34.5 for the given exam.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Number of correct answers = 18

Points of correct answer = 2 1/4 = 9/4

Scores of correct answer = 18 × 9/4 = 40.5

Number of incorrect answers = 18

Scores of incorrect answer = 12 × (-1/2) = -6

Total score = 40.5 - 6 = 34.5

Hence "The overall score of Rashida will be 34.5 for the given exam".

Answer: 40

Step-by-step explanation:

The concentration of pineapple when 2 gallons of pineapple juice are added to 6 gallons of the other juice is; 8.24

The function is a type of relation, or rule, that maps one input to a specific single output.

Given that the functions that model the concentration of apple juice in the drink after x gallons of the 20% drink are added to 2 gallons of pure juice.

f(x)=(2)(1.0)+x(0.2)²+x

If the concentration of apple when 2 gallons of apple juice are added to 6 gallons of the other juice;

f(6) = (2)(1.0)+ 6(0.2)²+ 6

f(6) = 2.0 + 6.24

f(6) = 8.24

Hence the concentration of pineapple when 2 gallons of pineapple juice are added to 6 gallons of the other juice is; 8.24

The slope is -5/4 and the equation of the line in point-slope form is       y-5 = -5/4(x+4) + c.

The slope or gradient of a line is a number that describes both the direction X and Y and the steepness of the line. It is the ratio of the vertical change to the horizontal change between any two distinct points on a line.

For the given situation,

The points are  (x1,y1) is (−4,5) and (x2,y2) is (0,0)

The formula of slope is

The approximate value of q in the logarithmic equation is 0.585.

The given logarithmic equation is  [tex]\rm q+log_2(6)=2q+2[/tex]

It is required to find the value of  'q'.

What is Logarithm?

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b=c\\\rm log_ac=b[/tex]

We have a logarithmic equation:

[tex]\rm q+log_2(6)=2q+2[/tex]

After simplification the above equation we get;

[tex]\rm q+log_2(6)=2q+2\\\rm q-2q=-log_2(6)+2\\\rm -q=-log_2(6)+2\\[/tex].....(1)

From the logarithmic table, we get the value of  [tex]\rm log_2(6)[/tex]

[tex]\rm log_2(6)=2.5849[/tex]  

Putting this value in equation (1), we get:

[tex]\rm -q=-log_2(6)+2\\\rm -q=-2.5849+2\\\rm -q=-0.5849\\\rm q=0.5849 \approx 0.585\\[/tex]

Thus, the approximate value of q in the logarithmic equation is 0.585.

Step-by-step explanation:

The table which most likely relates the height h(t), in meters, over time, t, in seconds  is: Option D:

If the height function is function of time 't', and the object's height is measured from the ground level and object never goes inside ground, then that means height can never be negative. It will always assume non-negative values.

There are three equations of motion that can be used when motion of the object is under constant acceleration and on a straight path.

They are listed below as:

[tex]v = u + at\\\\s = ut + \dfrac{1}{2} at^2\\\\v^2 = u^2 + 2as[/tex]

where the symbols have following meanings:

All the tables given except the last table have negative height values. That shows that if those negative valued tables are true, then the ball went inside ground.

Since no such event of ball going inside the ground is specified in the considered situation, thus, only the last table is valid here in terms of sign of height.

The last table is:

       t (in seconds)            h(t) (in meters)

       0                                180

       2                                160.4
       4                                101.6
       6                                3.6

Checking the truthfulness of the last table by using law of motion in straight path:

u = initial velocity of ball = 0

a = gravitational acceleration = -g ≈ -9.8 m/s sq.

Now, height of ball at time t = initial height of ball - distance it traveled from starting point in direction of reaching ground.

Thus, h(t) = 180 - |s| (assuming first value is true in the table)

where |s| = non-negative value of s

[tex]s= ut + (1/2)at^2\\s = 0t + (1/2)(-9.8)t^2\\\\|s| = 4.9t^2 \: \rm m/s^2[/tex]

Thus, h(t) = 180 - 5t² m/s sq.

[tex]h(2) = 180 - 4.9(2)^2 = 160.4\\h(4) = 180 - 4.9(4)^2 = 101.6\\h(6) = 180 - 4.9(6)^2 = 3.6\\[/tex]

Thus, the table which most likely relates the height h(t), in meters, over time, t, in seconds  is: Option D:

The choices that contain equivalent statements are:

a) ln 3x = 6 → 3x = e⁶

c) log 4x = 8 → 4x = 10⁸

e) 5.6554 = 10ˣ → log 5.6554 = x

To determine which choices contain equivalent statements, let's analyze each option one by one:

a) ln 3x = 6 → 3x = e⁶

This statement is true. It represents the inverse relationship between the natural logarithm (ln) and the exponential function with base e. Taking the exponential of both sides of the equation allows us to isolate the variable.

b) log 3x = 9 → 9x = 10³

This statement is not true. It seems to confuse the base of the logarithm. If the logarithm is not specified with a base, it is usually assumed to be base 10 (log base 10). In this case, the correct equivalent statement would be 3x = 10⁹.

c) log 4x = 8 → 4x = 10⁸

This statement is true. Similar to the previous option, assuming a base 10 logarithm (log base 10), the equivalent statement would be 4x = 10⁸.

d) 0.577 = e⁵ˣ → ln 5 = x / 0.577

This statement is not true. The equation given at the beginning, 0.577 = e⁵ˣ, cannot be transformed into the second equation using the properties of logarithms or exponentials. The two statements are unrelated.

e) 5.6554 = 10ˣ → log 5.6554 = x

This statement is true. It correctly represents the relationship between the logarithm and exponential functions. By taking the logarithm (base 10) of both sides of the equation, we can solve for x.

In summary, the choices that contain equivalent statements are:

a) ln 3x = 6 → 3x = e⁶

c) log 4x = 8 → 4x = 10⁸

e) 5.6554 = 10ˣ → log 5.6554 = x
