Answer:
-3 1/2 or -3.5
Step-by-step explanation:
* means multiply
just put 3 where the x is
so
f(x) = -2 ( 1 - 1/4 x )
f( -3) = -2 ( 1 - 1/4 * -3 )
f( -3) = -2 ( 1 3/4 )
f( -3) = - 3 1/2
A farmer is building a fence to enclose a rectangular area against an existing wall, shown in the figure below. Three of the sides will require fencing and the fourth wall already exists. If the farmer has 176 feet of fencing,
what is the largest area the farmer can enclose?
Answer: 46 ft by 92 ft
Step-by-step explanation:
The largest area is enclosed when half the fence is used parallel to the wall and the other half is used for the two ends of the fenced area perpendicular to the wall. Half the fence is 184 ft/2 = 92 ft. Half that is used for each end of the enclosure.

Solve the system of equations using determinants.
3x + 5y = 27
2x - y = -8
Find the values of determinants D, Dx and Dy
D=?
Dx=?
Dy=?
By simplificatiοn, the values οf the determinants are D = -13, Dx = -11, Dy = -60
What is a determinant οf a matrix?A determinant is a scalar value assοciated with a square matrix. The determinant οf a matrix can be used tο determine whether a matrix is invertible (i.e., has an inverse matrix) and whether a system οf linear equatiοns has a unique sοlutiοn, nο sοlutiοn, οr infinitely many sοlutiοns.
For a 2x2 matrix A = \(\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]\), the determinant is calculated as det(A) = ad - bc
To solve the system of equations using determinants, we need to set up the following matrix:
\(\left[\begin{array}{ccc}3&5\\2&-1\\\end{array}\right]\)
The determinant οf this matrix (D) is fοund by using the fοrmula:
D = (3)(-1) - (5)(2) = -13
Tο find the value οf Dx, we replace the x-cοefficients in the matrix with the cοnstants frοm the equatiοns:
\(\left[\begin{array}{ccc}27&5\\-8&-1\\\end{array}\right]\)
Then, we find the determinant οf this matrix:
Dx = (27)(-1) - (5)(-8) = -11
Tο find the value οf Dy, we replace the y-cοefficients in the matrix with the cοnstants frοm the equatiοns:
\(\left[\begin{array}{ccc}3&27\\2&-8\\\end{array}\right]\)
Then, we find the determinant οf this matrix:
Dy = (3)(-8) - (27)(2) = -60
Therefore, the values οf the determinants are:
D = -13
Dx = -11
Dy = -60

DeAndre rented a truck for one day there was a base fee of $19.99 and there was an additional charge of $.92 for each mile driven DeAndre had to pay $205.83 when he rented the truck for how many miles did he drive the truck
Total miles driven by DeAndre on the rented truck is 2020 miles .
What is rented object?
A car/truck rental, hire car/truck , or car hire agency is a company that rents automobiles to the general public for short periods of time, typically ranging from a few hours to a few weeks.
Main body:
According to question:
Base fee for truck rent = $19.99
Additional charge for each mile = $0.92
Total he had to pay = $205.83
Let the total no. of miles driven = x
The equation becomes ⇒
Total paid = base fee + no. of miles * rent for each mile
205.83 = 19.99 + 0.92*x
205.83 - 19.99 = 0.92 x
185.84 = 0.92 x
x= 185.84/ 0.92
x = 2020 miles
Hence the total miles driven by DeAndre are 2020 miles.

Comparing Marbles:
Red balloons float purple marbles at a ratio of 12: 4.
Red balloons float green marbles at a ratio of 15: 6.
Which is heavier: a purple marble or a green marble?
The marble that is heavier based on the ratio is purple marble.
What is ratio?Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).
This indicates that you're dividing information A by B. For instance, the ratio will be 5/10 if A is 5 and B is 10.
Red balloons float purple marbles at a ratio of 12: 4. This will be:
= 12/4
= 3
Red balloons float green marbles at a ratio of 15: 6. This will be:
= 15/6
= 2.5
In this case, the purple marble is heavier as 3 is more than 2.5.

In the whole number 70,819 the place value of the digit 1 is
Step-by-step explanation:
a number is a sequence of digits with every position being multiplied by increasing powers of 10.
and the whole number is then the sum of of these little multiplications.
the first position left of the decimal point is for 10⁰ (1). the second position is 10¹ (10). the third position for 10² (100). and so on.
the given number is therefore just the short version of
7×10⁴ + 0×10³ + 8×10² + 1×10¹ + 9×10⁰
and therefore, the digit 1 in this number has the value 1×10¹ = 10, which is also the place value, 10¹ = 10.

Take a strip of paper, put two half twists in it, and glue the ends together. Now cut it lengthwise while hugging the right edge. What do you get?
The answer of the given question based on graphing and crafting is you will create a Mobius strip , and when we cut it into lengthwise you will get a single, longer Mobius strip.
What is Mobius strip?A Möbius strip is a one-sided surface with only one boundary component. It is named after the German mathematician August Ferdinand Mobius who discovered it in 1858.
A Mobius strip can be created by taking rectangular strip of paper, giving it half-twist, and then connecting two ends of strip together to form loop. The resulting loop will have interesting property of being non-orientable, which means that it only has one side.
If you take a strip of paper, put two half-twists in it, and glue the ends together, you will create a Mobius strip.
When you cut a Mobius strip length wise down the middle while hugging the right edge, you will get a single, longer Mobius strip that has two full twists instead of the original two half twists. This is because cutting down the middle of the Mobius strip results in flipping one of the twists, which combines with the original twist to create a double twist.

Rewrite y=2(1.06)9t in the form y=a(1+r)t or y=a(1−r)t to determine whether it represents exponential growth or exponential decay. Round a and r to the nearest hundredth if necessary.
The function is an exponential growth function
How to determine the type of the functionThe function is given as
y=2(1.06)^9
We can begin by rewriting the given equation as:
y = 2 * 1.06t
So, we have
y = 2 * (1 + 0.06)^t
Now we can see that the equation is in the form y = a*b^t,
where a = 2 and b = 1.06^9
This equation represents exponential growth because the base of the exponent, b = 1.06, is greater than 1.
We can re-write it in the form y = a(1+r)t,
we can find the value of r by subtracting 1 from 1.06 which is 0.06 and the value of a is 2.
so we have y = 2(1+0.06)^t
So, the equation represents exponential growth with a = 2 and r = 0.06

The slope of a line is determined by its steepness.
The formula for calculating slope is expressed as;
\(\frac{\triangle y}{\triangle x} = \frac{y_2-y_1}{x_2-x_1}\)
For the first graph, we can assume the coordinates (-1, 0) and (0, -2), the \(\frac{\triangle y}{\triangle x} = \frac{-2-0_1}{0-(-1)}\\\frac{\triangle y}{\triangle x} = \frac{-2}{1}\\\frac{\triangle y}{\triangle x} = -2\\\\\)
Since the slope is -2 which is a negative value, hence the slope of LlNE 1 is negative
For the vertical line, since the line is parallel to the y axis and the change in the x-value is zero, hence the slope of LINE 2 will be UNDEFINED
For the THIRD graph, we can assume the coordinates (2, 0) and (0, -2), the \(\frac{\triangle y}{\triangle x} = \frac{-2-0}{0-2}\\\frac{\triangle y}{\triangle x} = \frac{-2}{-2}\\\frac{\triangle y}{\triangle x} = 1\\\\\)
Since the slope is 1 which is a negative value, hence the slope of LlNE 3 is positive
For the horizontal line (fourth graph), since the line is parallel to the x-axis and the change in the y-value is zero, hence the slope of LINE 4 will be ZERO

In this triangle, the product of sin B and tan C is , and the product of sin C and tan B is .
The product of sin B and tan C is c/a.
The product of sin C and tan B is b/a.
Given is a right triangle, ABC, we need to find the product of sin B and tan C and the product of sin C and tan B,
So, we know,
Sine = Opposite ÷ Hypotenuse.
Cosine = Adjacent ÷ Hypotenuse.
Tangent = Opposite ÷ Adjacent.
Therefore,
Sin B = b/a
Tan C = c/b
Sin B x Tan C = b/a x c/b = c/a
And,
Sin C = c/a
Tan B = b/c
Sin C x Tan B = c/a x b/c = b/a
Hence the products are c/a and b/a.
