Answer: \((x-3)^2+(y+4)^2=64\)

Step-by-step explanation:

The equation of a circle is \((x-h)^2+(y-k)^2=r^2\). h and k are the points of the center corresponding with x and y respectively. r is radius. All we have to do is plug the values in.

\((x-3)^2+(y-(-4))^2=8^2\)

With our values plugged in, we can now simplify.

\((x-3)^2+(y+4)^2=64\)

Therefore, our final equation is \((x-3)^2+(y+4)^2=64\).

According to the Pythagorean theorem, The Answer is Yes the third side is greater than 1 foot.

A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

p=1 foot

b=1 foot

\(h^{2} = p ^{2} + b ^{2}\)

\(h=\sqrt {1^{2}+1^{2}}\\=\sqrt 2\\=1.41\\\)

Answer:

130° and 310°

Step-by-step explanation:

the bearing of A from B is the measure of the clockwise angle from a north line at B to A

the angle at B and A are same- side interior angles and sum to 180°

angle at B = 180° - 50° = 130°

the bearing of A from B is then 130°

the bearing of B from A is the measure of the clockwise angle from the north line at A to B

the complete angle about A = 360° then clockwise angle from north line at A to B is

360° - 50° = 310°

the bearing of B from A is 310°

Step-by-step explanation:

1. Based on the given information, set up a proportion;

Given;

1/6 of a bottle was filled in 1/4 minute

Equation;

1/6 : 1/4

2. Solve the equation;

1/6 : 1/4

Multiply both sides by 6, to make it such that the whole bottle is filled,

1/6 : 1/4

Based on the information in the triangle, the measure of ZDEB is 54°.

A triangle is a polygon with three sides and three angles. It is one of the basic shapes in geometry. Triangles are commonly represented by drawing three line segments that connect three non-collinear points. The points where the line segments intersect are called the vertices of the triangle, and the line segments themselves are the sides of the triangle.

The sum of the measures of the angles of a triangle is 180 degrees. Therefore,

mZAEC + m/AED + mZDEB = 180

(2x+4) + (5x+1) + mZDEB = 180

7x+5 = 180

7x = 175

x = 25

mZDEB = 2x+4 = 2(25)+4 = 54 degrees

Hence, the answer is 54

Answer:

f⁻¹(7) = 1

Step-by-step explanation:

Step 1: Write out function

f(x) = 3x + 4

Step 2: Find f⁻¹(x) (or known as inverse f(x))

y = 3x + 4

x = 3y + 4

-3y + x = 4

-3y = 4 - x

y = -4/3 + x/3

Step 3: Plug in 7 into inverse f(x)

f⁻¹(7) = 7/3 - 4/3

f⁻¹(7) = 3/3

f⁻¹(7) = 1

Answer: Guy above me is right

Step-by-step explanation:

Answer:

I. 60%

II. 75.4 kg

Step-by-step explanation:

We will use the z-scores and the standard normal distribution to answer this questions.

We have a normal distribution with mean 69 kg and variance 25 kg^2 (therefore, standard deviation of 5 kg).

I. What percentage of adult male in Boston weigh more than 72 kg?

We calculate the z-score for 72 kg and then calculate the associated probability:

\(z=\dfrac{X-\mu}{\sigma}=\dfrac{72-69}{5}=\dfrac{3}{5}=0.6\\\\\\P(X>72)=P(z>0.6)=0.274\)

II.  What must an adult male weigh in order to be among the heaviest 10% of the population?

We have to calculate tha z-score that satisfies:

\(P(z>z^*)=0.1\)

This happens for z=1.28 (see attachment).

Then, we can calculate the weight using this transformation:

\(X=\mu+z^*\cdot\sigma=69+1.28\cdot 5=69+6.4=75.4\)

Answer:

2.4 and 177.6

Step-by-step explanation:

Let Angle 1 be x

This means Angle 2 is x+175.2

Since supplementary angles add up to 180 we can write the following equation:

x+x+175.2=180

2x+175.2=180

Subtract 175.2 from both sides

2x=4.8

Divide 2 by both sides

x=2.4

Angle 1 is 2.4

Angle 2 is 2.4+175.2=177.6

The function that expresses the accumulated capital as a function of time (in years) as compound interest is \(A(t) = 120,000(1 + 0.03)^t\).

We have,

The formula to calculate the accumulated capital over time with compound interest is:

\(A = P(1 + r/n)^{nt}\)

Where:

A: accumulated capital after time t

P: initial principal or investment

r: annual interest rate as a decimal

n: number of times interest is compounded per year

t: time in years

In this case,

P = 120,000 soles, r = 0.03 (3% as a decimal), n = 1 (compounded annually). Therefore,

The function that expresses the accumulated capital as a function of time (in years) is:

\(A(t) = 120,000(1 + 0.03)^t\)

Simplifying the expression, we have:

\(A(t) = 120,000(1.03)^t\)

So, for example,

If the money is kept in the bank for 5 years, the accumulated capital will be:

\(A(5) = 120,000(1.03)^5\)

= 141,158.38 soles

Thus,

The function that expresses the accumulated capital as a function of time (in years) is:

\(A(t) = 120,000(1 + 0.03)^t\)

Here it is given that the function f(x) can serve as a probability distribution of the discrete random variable X when f(x) = c(x² + 4), for x = 0, 1 ,2

We have to find the value of c

Since f(x) represents the probability distribution x = 0, 1 ,2

So we have f(0)+f(1)+f(2)=1

c(0²+4)+c(1²+4)+c(2²+4)=1

\( t = 4x \)

Step-by-step explanation:

We are given that in 1 month, Jessica takes 4 business trips. Take 4 as our coefficient or constant.

Let t be the total number of business trips Jessica has taken.

For 1 month, 4 trips are taken.

For x months, total business trips taken will be expressed as,

\( t = 4x \)

Let's say for example, we have 5 months in a row, i.e. x = 5. Total business trips taken by Jessica can be gotten by simply plugging in the value of x.

\( t = 4(5) = 20 trips \)

In 5 months in a row, Jessica takes 20 business trips.

\(w^2 - 6w + 4\) is a polynomial that represents how much more profit is earned by selling w apple trees than w pear trees.
