A baby monitor picks up signals within a 50 meter radius. How many square meters of coverage does the baby monitor provide?

The factored forms are [tex]\((p + 4c)(p - 4c - 1)\)[/tex] for the first expression and [tex]\(-(x - 7)(y - 7)\)[/tex] for the second expression.

Let's factor the given expressions:

1. [tex]\(p^2 - 16c^2 - p - 4c\)[/tex]:

  To factor this quadratic expression, we can use the difference of squares formula, [tex]\(a^2 - b^2 = (a + b)(a - b)\)[/tex]. In this case, [tex]\(p^2 - 16c^2\)[/tex] is a difference of squares, so we can factor it as [tex]\((p + 4c)(p - 4c)\)[/tex]. The remaining terms are [tex]\( - p - 4c\)[/tex], and thus, the factored form is [tex]\((p + 4c)(p - 4c) - (p + 4c)\)[/tex]. Factoring out the common factor of -1 from the last two terms gives us the final factored expression: [tex]\((p + 4c)(p - 4c - 1)\)[/tex].

2. [tex]\(x^2 - 7x + 7y - y^2\)[/tex]:

  This expression is a quadratic trinomial, and to factor it, we need to find two binomials whose product equals the given expression. The expression can be rewritten as [tex]\(x^2 - 7x - y^2 + 7y\)[/tex]. Now, we can group the terms as [tex]\((x^2 - 7x) - (y^2 - 7y)\)[/tex]. Factoring out \(x\) from the first group and y from the second group, we get [tex]\(x(x - 7) - y(y - 7)\)[/tex]. Now, we notice that both terms have a common factor of -1, so we can factor that out to obtain the final result: [tex]\(-(x - 7)(y - 7)\)[/tex].

To find the value of x for which WXYZ must be a parallelogram, set up an equation by equating the lengths of opposite sides. Solve the equation to find the value of x.

To find the value of x for which WXYZ must be a parallelogram, we first need to understand the properties of parallelograms. One important property is that opposite sides are equal in length. Given that WZ = XY, we can set up an equation: 4x + 20 = x + 26. By solving this equation, we can find the value of x.

4x + 20 = x + 26

Subtracting x from both sides, we get:

3x + 20 = 26

Subtracting 20 from both sides, we get:

3x = 6

Dividing both sides by 3, we get:

x = 2

Answer:           Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same.

Step-by-step explanation :   For example, think about the fraction 1/2. It means half of something. You can also say that 6/12 is half, and that 50/100 is half. They represent the same part of the whole. These equivalent fractions contain different numbers but they mean the same thing: 1/2 = 6/12 = 50/100

Multiply both the numerator and denominator of a fraction by the same whole number. As long as you multiply both top and bottom of the fraction by the same number, you won't change the value of the fraction, and you'll create an equivalent fraction.

The slope-intercept form is y = 2x-3.

Step-by-step explanation:

Given,

Comparing the given equation with general equation, it can be determined that :

m = 2 and c = 7 (y-intercept).

The given line passes through the point (3,3) which is equal to (x1,y1)

Therefore, x1=3 and y1=3.

Answer: 1) 1 1/2, 2 1/4, and 4

Step-by-step explanation: 1) We know that the equation would be the cups of flour being multiplied by the batches. Like, 5 times 3/4 would equal 15/4 which would simplify to 3 3/4.

                 So, to find the first missing number, we do 2 x 3/4, which equals 6/4( 1 1/2).

                The next missing number would be 3, because we're going in order-- like 1, 2, 3, 4. So we do 3 x 3/4.

               We then don't have a number for batches this time. So we still do, 3/4 x 3 but this time we cross out both the 3 on the top and we're left with 4, our answer.

                The equation for this is 3/4 x b. (Did this help..?)

Answer:

7.071 cm

Step-by-step explanation:

Final answer:

To find the length AG in the cuboid ABCDEFGH, use the three-dimensional Pythagorean theorem twice. First finding the diagonal AC (which is equal to 5 cm), and then using it to find AG. The length AG, to three significant figures, is approximately 7.07 cm.

Explanation:

The length AG of a cuboid ABCDEFGH can be found by using the Pythagorean theorem in three dimensions. This theorem is an extension of the traditional Pythagorean theorem used in two dimensions. For the given cuboid, we start by using the Pythagorean theorem on triangle ABC to find the diagonal AC. The formula for the Pythagorean theorem is:

c2 = a2 + b2

Where c is the diagonal and a and b are the sides of the right triangle:

AC2 = AB2 + BC2

Plugging in the given values, we have:

AC2 = 32 + 42 = 9 + 16 = 25

So, AC = 5 cm.

Now, to find AG, we use the diagonal AC and side CG in another application of the Pythagorean theorem for the right triangle ACG:

AG2 = AC2 + CG2

AG2 = 52 + 52 = 25 + 25 = 50

AG = √50 ≈ 7.071 approximately.

Therefore, the length AG, expressed to three significant figures, is approximately 7.07 cm.

Here is the graph for the equation

Given function to be graphed is,

f(x) = (x - 2)(x - 6)

We will convert the equation of the function into the vertex form,

(x - 2)(x - 6) = x(x - 6) - 2(x - 6)

                  = x² - 6x - 2x + 12

                  = x² - 8x + 12

                  = x² - 2(4x) + 16 - 4

            f(x) = (x - 4)²- 4

By comparing this equation with the vertex form of the equation of a parabola,

g(x) = a(x - h)² + k

Here, (h, k) is the vertex of the parabola.

Therefore, vertex of the function 'f' will be (4, 4).

Now we will find the x-intercepts and y-intercept of the function.

For x-intercept, put f(x) = 0

0 = (x - 4)²- 4

(x - 4) = ±2

x = 4 ± 2

x = 2, 6

Therefore, x-intercepts of the function are (2, 0) and (6, 0).

For y-intercept, put x = 0

f(0) = (0 - 2)(0 - 6)

f(0) = 12

Therefore, y-intercept of the function is (0, 12).

By plotting these ordered pairs and joining them by a curve we can get the graph of the parabola.

Answer:

10.92m

Step-by-step explanation:

See attached picture for more illustration

Using SOH CAH TOA,

Tan 20° = opposite / adjacent

Tan 20° = x / 30

x = 30 * tan20

x = 10.919m = 10.92m

The height of the tree is 10.92m

Final answer:

The height of the cat in the tree is 10.44m

Explanation:

The question involves finding the height of a cat caught in a tree using trigonometry, specifically the tangent function. If the firefighter is standing 30m from the base of the tree and the angle to the cat is 20 minutes (which should be converted to degrees for typical trigonometric calculations), we can calculate the height of the cat in the tree. First, we need to convert the angle from minutes to degrees. Since 1 degree = 60 minutes, 20 minutes is equal to 20/60 degrees or approximately 0.33 degrees.

To find the height of the cat, we can use the tangent function (tan) in trigonometry, which is the ratio of the opposite side (the height of the cat in the tree, which we're trying to find) to the adjacent side (the distance from the firefighter to the base of the tree). Thus, the formula becomes height = tan(angle) × distance.

Using the formula:

distance = 30m

angle = 0.33 degrees

height = tan(0.33 degrees) × 30

Tan(20') x Distance

Calculating: Height = Tan(20') x 30m = 10.44m

Answer:

682,500 people

Step-by-step explanation:

so just find how many people per year it grows by then add that number 15 times to 300,000

so 8.5% of 300,000 is 25,500 people

now multiply that by 15 to get 382,500

add that to 300,000

Final answer:

Using the exponential growth formula, the population of a city with an initial population of 300,000 and an annual growth rate of 8.5% will be approximately 962,100 after 15 years.

Explanation:

To calculate the future population of a city with an initial population of 300,000 people and an annual growth rate of 8.5% over 15 years, we use the formula for exponential growth:

P = P_0 (1 + r)[tex]^{t}[/tex]

where:

P is the future population,

P_0 is the initial population (300,000),

r is the annual growth rate (expressed as a decimal, so 8.5% becomes 0.085), and

t is the number of years (15).

Substituting the values we get:

P = 300,000 (1 + 0.085)¹⁵

Calculating this, we find:

P = 300,000 (1.085)¹⁵

P = 300,000 (3.207)

P ≈ 962,100

Therefore, after 15 years, the population is expected to be approximately 962,100, rounding to the nearest whole number.
