Answer:

5, -5

Step-by-step explanation:

We have the problem x^2+5=30

Same to both sides

x^2=25

And 25 is a perfect square, x = 5

BUUUUUUUT..........

x could also equal to -5 because no numbers that are squared can be negative

Confused?

Squaring a number means doing the number multiplied by itself

A negative multiplied by a negative equals a positive

A positive multiplied by a positive equals a positive

Under no circumstances can something squared be a negative number

-5*-5 also equals 25.

So those are your two numbers

x=2645/5832 hope that helped

Step-by-step explanation:

Answer:

Median is 10 and mean is 13.5

a. The input range where there may be significant errors in evaluation is when x is very large or very small.

b. The input range where there may be significant errors in evaluation is when x is very close to multiples of π.

For a, In these cases, significant figures may be lost in the subtraction of two nearly equal numbers (√x and -√x, and 1/x and -1/x). To avoid this error, we can simplify the expression to 0.

For b, This is because the sine function has a maximum error of 1 in the vicinity of these points, which can cause cancellation errors in the subtraction of 1 and sin x. To avoid this error, we can use the identity:

This expression avoids subtraction and reduces error using the more stable cosine function.

Using the exponential growth formulas, we get the population at 10 years would be 2593.

What is exponential growth?

A process called exponential growth sees a rise in quantity over time. It happens when the derivative of a quantity's instantaneous rate of change with respect to time is equal to the original quantity.

Given Initial population is Pt= 1725.

The doubling time of the population is D=17

Now we need to find the population at time t=10

Using the formula,

\(P_{t}=P_{0} (2)^{\frac{t}{D} } \\P_{t}=1725 (2)^{\frac{10}{17} } \\P_{t}=1725 (2)^{0.588}\\P_{t}=1725 \space\ . \space\ 1.503\\P_{t}=2593\)

Hence the population of the island in 10  years would be 2593.

Answer:

\(\huge{\boxed{\boxed{\tt { ⎆ \ Pythagorean \ Theorem :-}}}} \ \)

\(a {}^{2} + b {}^{2} = c {}^{2} \)

This is the formula for the pythagorean theorem i.e, one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

Answer:

\(a^2+b^2=c^2\) is the formula for the Pythagorean Theorem

Step-by-step explanation:.

The Pythagorean Theorem, also referred to as the ‘Pythagoras theorem,’ is arguably the most famous formula in mathematics that defines the relationships between the sides of a right triangle. This mathematical law states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.

Step-by-step explanation:

The store owner needs to mix 35 pounds of back tea.

Let's Assume

considering the weighted average of the prices of the individual teas.

The total cost of the oolong tea = 35 * 2.40 = $84.

cost of x pounds of black tea is y dollars

To find the total cost of the mixture, we add the cost of the black tea to the cost of the oolong tea:

The total weight of the mixture is the sum of the weights of the oolong tea and the black tea:

Total cost / Total weight = $2.10

Substituting the values, we get:

($84 + y) / (35 + x) = $2.10

($84 + 1.80x) / (35 + x) = $2.10

To solve for x, we can multiply both sides of the equation by (35 + x):

$84 + 1.80x = $2.10(35 + x)

$84 + 1.80x = $73.50 + $2.10x

$1.80x - $2.10x = $73.50 - $84

-0.30x = -$10.50

Dividing both sides by -0.30, we have:

x = -$10.50 / -0.30

x = 35

Therefore, the store owner needs to mix 35 pounds of black tea .

Answer:

16

Explanation:

The segment with a length equal to 12 is tangent to the circle, It means that it forms an angle of 90 degrees with the line of the missing length.

So, the formed triangle is a right triangle and we can apply the Pythagorean theorem to solve the question.

Then, since 20 is the hypotenuse of the triangle, we get that the missing side can be calculated as:

So, solving the expression, we get:

Therefore, the segment length is 16.

Miguel served 23 orders, Ahmad served 46 orders, and Jane served 15 orders at the school cafeteria on Monday.

To solve this problem, let's assign variables to represent the number of orders served by each person. Let's say Miguel served x orders.
According to the information given, Ahmad served 2 times as many orders as Miguel, so Ahmad served 2x orders.
Jane served 8 fewer orders than Miguel, so Jane served (x - 8) orders.
The total number of orders served by all three is 84, so we can set up the equation:
x + 2x + (x - 8) = 84
Simplifying the equation, we have:
4x - 8 = 84
Adding 8 to both sides of the equation:
4x = 92
Dividing both sides by 4:
x = 23

Now we can find the number of orders served by each person:

Miguel served 23 orders.
Ahmad served 2 * 23 = 46 orders.
Jane served 23 - 8 = 15 orders.

In conclusion, Miguel served 23 orders, Ahmad served 46 orders, and Jane served 15 orders at the school cafeteria on Monday.

71 + x = 180

x = 180 -71

Just write down exactly what it says!

The perimeter of a rectangle is 68 inches

68

The perimeter equals twice the length of L inches

68 = (2 × L)

Plus twice the width of 9 inches.

68 = (2 × L) + (2 × 9)

Now just clean up the equation.

68 = 2L + (2 × 9)

68 = 2L + 2(9)

The ratio by mass of copper to zinc in the alloy is 3:1.

To find the ratio by mass of copper to zinc in the alloy, we need to first calculate the total mass of the alloy. We can do this by adding the mass of copper and zinc:

Total mass of alloy = 13.5 g + 4.5 g = 18 g

Now we can find the ratio of copper to zinc by dividing the mass of copper by the mass of zinc:

Ratio of copper to zinc = 13.5 g / 4.5 g = 3:1

Therefore, the ratio by mass of copper to zinc in the alloy is 3:1.

Step-by-step explanation:

The power series representation for the function f(x) = x sin(4x) can be found as follows:

Firstly, we can find the power series representation of sin(4x) using the formula for the sine function:$

$\sin x = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!}x^{2n+1}$$

Substitute 4x for x to obtain:$$\sin 4x

= \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!}(4x)^{2n+1}

= \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!}4^{2n+1}x^{2n+1}$$

Multiplying this power series by x gives:

$$x\sin 4x

= \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!}4^{2n+1}x^{2n+2}$$

Therefore, the power series representation for the function

f(x) = x sin(4x) is:$$f(x)

= x\sin 4x

= \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!}4^{2n+1}x^{2n+2}$$

Therefore, the power series representation for the function f(x) = x sin(4x) is:$$f(x) = x\sin 4x = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n+1)!}4^{2n+1}x^{2n+2}$$
