Answer:

f(-2) = 2

Step-by-step explanation:

I'm assuming "-6x2" is actually "6x^2"

f(x) = -6x^2 - 5x + 4

Plug in -2 for the x's

f(-2) = -6(-2)^2 - 5(-2) +4

f(-2) = -6(2) - 5(-2) + 4

f(-2) = -12 + 10 + 4

f(-2) = -12 + 14

f(-2) = 2

Final answer:

To find the width of a rectangular state park with an area of 84 square miles where the length is 2 miles longer than twice the width, we set up a quadratic equation and solve for the width. The width of the park is 6 miles.

Explanation:

The question involves solving a quadratic equation to find the width of a rectangular state park where the length is 2 miles longer than twice its width, and the area is 84 square miles. To solve this problem, let's let w represent the width of the park.

According to the problem, the length l can be expressed as:

l = 2w + 2

The area A of a rectangle is given by the formula:

A = l × w

Substituting the given area and the expression for the length, we have:

84 = (w)(2w + 2)

Which simplifies to:

84 = 2w² + 2w

And further simplifies to:

0 = 2w² + 2w - 84

Dividing the entire equation by 2 to simplify:

0 = w² + w - 42

Now, we solve this quadratic equation for w, the width of the park. Using the quadratic formula or factoring (if possible), we find the positive value of w, which could be the width of the park since a width can't be negative:

w = 6

So, the width of the park is 6 miles.

Answer:

W= 2.1

Step-by-step explanation:

The solution to the equation 1.5 = 0.6( w + 0.4 ) is w = 2.1.

Given the equation in the question:

1.5 = 0.6( w + 0.4 )

To solve the equation 1.5 = 0.6(w + 0.4) for "w," first apply distributive property:

1.5 = 0.6( w + 0.4 )

Distribute 0.6 on the right side of the equation:

1.5 = 0.6(w) + 0.6(0.4)

Simplifying, we get:

1.5 = 0.6w + 0.24

Subtract 0.24 from both sides of the equation:

1.5 - 0.24 = 0.6w + 0.24 - 0.24

1.5 - 0.24 = 0.6w

1.26 = 0.6w

0.6w = 1.26

To solve for "w", divide both sides by 0.6:

0.6w / 0.6 = 1.26 / 0.6

w = 1.26 / 0.6

w = 2.1

Therefore, the value of w is 2.1.

Answer:

The measure of the arc CD = 64°

Step-by-step explanation:

It is required to find the measure of the arc CD in degrees.

So, as shown at the graph

BE and AD are are diameters of circle P

And ∠APE is a right angle ⇒ ∠APE = 90°

So, BE⊥AD

And so, ∠BPE = 90° ⇒(1)

But it is given: ∠BPE = (33k-9)° ⇒(2)

From (1) and (2)

∴ 33k - 9 = 90

∴ 33k = 90 + 9 = 99

∴ k = 99/33 = 3

The measure of the arc CD = ∠CPD = 20k + 4

By substitution with k

∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°

Answer:

$225 of birthday money

Step-by-step explanation:

he spent 20 percent (1/5) of the money on dog treats, and the remaining 80 percent (4/5) went to 3 different charities. If $60 dollars were given to each charity, that means a total of $180 dollars was given to charity. if 4/5 of the money is equal to $180, we can divide 180 by 4 to get $45 dollars. this means that 1/5 of the birthday money would be equal to $45 dollars. so to find 5/5, or 100% of the money, simply multiply $45 by the denominator, 5, to get the answer. the total birthday money received was $225 dollars, and $45 dollars of that was used for dog treats.

The amount of money Mr. Thompson received for his birthday, work backwards from how much he donated to charities after spending 1/5 on dog treats, resulting in $300.

To find out how much money Mr. Thompson received for his birthday, we will work backwards from the information given.

Let's assume he received x amount of money for his birthday.

He spent 1/5 of it on dog treats, so he spent (1/5)x on dog treats.

The remainder after buying the dog treats is (4/5)x.

Since he divided this among 3 charities, each charity received $60, so [tex](\frac{4}{5} )x = 3*60.[/tex]

Solving this equation, we find x = $300.

Hence, Mr. Thompson received $300 for his birthday.

Answer:

First, you know that a triangle has 180° total. So, you take 180-38-25 and that equals 117. So the corner inside the triangle is 117. So a straight line is also equal to 180. You take 180-117 and that is 63. 4x+3 = 63. You subtract 3 from both sides and get 4x = 60. To get x by itself you divide by 4 and x = 15.

Answer:

you could graph y = 1.5x and y=60, then the intersection at (40,60) represents the solution of the equation.

The 1 copy makes the cost equivalent in two options and the cost of 1 copy is $41.

Step-by-step explanation:

The given information are that,

Elsa could use a printer in which it cost a $38 setup fee and $3 for each copy.

Elsa could go to a supply store in which it cost $36 up-front fee and $5 for each copy.

To find the same amount for certain number of copies in both the cases :

Let us assume that the number of copies be 'x'.

In the first case, the total cost will be = setup fee + cost for x copies.

⇒ Total cost = 38 + 3x

In the second case, the total cost will be = up-front fee + cost for x copies.

⇒ Total cost = 36 + 5x

To find the x value :

Equating the total cost of both the cases, we get

⇒ 38 + 3x = 36 + 5x

⇒ 38-36 = 5x-3x

⇒ 2 = 2x

⇒ x = 1 copy

Therefore, taking 1 copy make the two options equivalent in terms of cost.

The cost of 1 copy = 38+ 3(1) = 41 dollars.

Therefore, it would cost $41 for 1 copy.

5.728 rounds up to 6 because it is greater than 5.50 and 2.317 rounds down to 2 since it is less than 2.5. 6 - 2 = 4.

Final answer:

To estimate the difference between 5.758 and 2.317, you round 5.758 up to 6 and 2.317 down to 2, and then subtract to get an estimated difference of 4.

Explanation:

The student is asking how to estimate the difference between two numbers by rounding them to the nearest whole number before subtracting.

To estimate the difference between 5.758 and 2.317, we first round each number to the nearest whole number:

5.758 rounds up to 6 because the first digit after the decimal (7) is greater than 5.

2.317 rounds down to 2 because the first digit after the decimal (3) is less than 5.

After rounding the numbers, we perform the subtraction:

6 - 2 = 4

Therefore, the estimated difference is 4.

Compound interest is the concept discussed in this question. It refers to the interest calculated on both the initial principal amount and any accumulated interest from previous periods.

Explanation:

The subject of this question is Mathematics. Specifically, it relates to the concept of compound interest. Compound interest is the interest that is calculated on both the initial principal amount and any accumulated interest from previous periods. In this case, Angela is choosing between having $1,000 now or investing it in a savings account to have $1,050 a year from now. The $50 earned is the result of the interest earned on the initial $1,000.

Answer:

B: M

C: Side AB is 20ft

C: Perimeter = 96ft

Perimeter is 2l+2w in the case of a rectangle, so you would write:

2(4x - 4.25) + 2(7x +7)

Answer: The expression can be written as Perimeter = 22x + 5.5

Step-by-step explanation: The perimeter of a rectangle is given as 2(L + W), where L is the length and W is the width. In the question, the length L has been given as 7x + 7 while the width W has been given as 4x - 4.25.

Inserting the values of the length and the width, the perimeter can now be properly written as,

Perimeter = 2(L + W)

Perimeter = 2( {7x + 7} + {4x - 4.25} )

By collecting like terms we now have

Perimeter = 2(11x + 2.75)

Perimeter = 22x + 5.5

Answer:

23

Step-by-step explanation:

Sum of angles = (n - 2) x 180

3780 = (n - 2) x 180             Divide both sides by 180

21 = n - 2

+ 2     + 2                              Add 2 to both sides

23 = n

The shape has 23 sides.

If this answer is correct, please make me Brainliest!

The polygon having the sum of the interior angles 3780° have 23 sides.

The inner of the two angles formed where two sides of a polygon come together is called the interior angle.

Given that, the sum of the interior angles of a polygon is 3780, we need to find the number of sides of the polygon,

We know that,

The formula for calculating the sum of interior angles is (n-2) × 180° where is the number of sides.

Therefore,

3780° = (n-2)×180°

n-2 = 3780° / 180°

n-2 = 21

n = 21+2

n = 23

Hence, the polygon having the sum of the interior angles 3780° have 23 sides.
