Identify the hyperbolas (represented by equations) whose centers are at (2, 1)

Answers

Answer 1
When the transverse axis is horizontal, a hyperbola centered at (h,k) has formula (x-h)^2/a^2-(y-k)^2/b^2=1. Plug in h=2, k=1, the formula is (x-2)^2/a^2-(y-1)^2/b^2=1 for some a,b. If the transverse axis is vertical, the formula is (y-h)^2/a^2-(x-k)^2/b^2=1, and (y-2)^2/a^2-(x-1)^2/b^2=1 in our case.

PLEASE PLEEEASE HELP ME IM BEGGING YOU WITH ALL MY HEART YOU GET 20 POINTS Solve for m:(m-4)^3 = (1/8)^-1

Answers

You can simplify the right side. Then, you need to take cube roots.
  (m -4)³ = 1/(1/8) . . . rule of exponents
  (m -4)³ = 8 . . . . . . .simplify
  m -4 = ∛8 . . . . . . . take cube roots
  m -4 = 2 . . . . . . . . use your calculator or knowledge to find ∛8
  m = 6 . . . . . . . . . . add 4

The solution is m = 6.

_____
If you subtract the right side, you get a function of m that is zero when m has the right value. This graph shows that value is m = 6.
Your answer will be m=6. All you have to do is just take the square root of both sides and solve. Take the cubed root for each side of the equation t and set up an equation for m. then remove the perfect root factor, m-4 under the radical to solve for m. remove the negative exponent by writing (1/8)^-1 as 8. simplify the right side move all terms not containing m to the right side of the equation. since -4 does not contain  the variable to solve for, move it to the right side by adding 4 to both sides. then add 4+2 to get 6.

the sum od the squares of two consecutive even integers is 164. Find the integers.

Answers

Let x be the smaller integer, then x+2 is the larger integer.
We're given 
x^2+(x+2)^2=164
Expand and simplify
2x^2+4x+4=164
x^2+2x-80=0
(x-8)(x+10)=0
=> x=-10 or x=8.

Therefore the integers are{8,10} or {-10,-8}.
Note: question asks for integers, so negative integers count.

The consecutive even integers whose squares sum to 164 are [tex]\(8\) and \(10\) or \(-10\) and \(-8\).[/tex]

Let the two consecutive even integers be  [tex]\( x \) and \( x + 2 \).[/tex]

The sum of their squares is given by:

[tex]\[ x^2 + (x + 2)^2 = 164 \][/tex]

Expanding and simplifying this equation:

[tex]\[ x^2 + (x^2 + 4x + 4) = 164 \]\[ 2x^2 + 4x + 4 = 164 \]\[ 2x^2 + 4x + 4 - 164 = 0 \]\[ 2x^2 + 4x - 160 = 0 \]\[ x^2 + 2x - 80 = 0 \][/tex]

Now, solve the quadratic equation [tex]\( x^2 + 2x - 80 = 0 \).[/tex]  We use the quadratic formula  [tex]\( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \),[/tex]  where [tex]\( a = 1 \), \( b = 2 \), and \( c = -80 \).[/tex]

[tex]\[ x = \frac{-2 \pm \sqrt{2^2 - 4 \cdot 1 \cdot (-80)}}{2 \cdot 1} \]\[ x = \frac{-2 \pm \sqrt{4 + 320}}{2} \]\[ x = \frac{-2 \pm \sqrt{324}}{2} \]\[ x = \frac{-2 \pm 18}{2} \][/tex]

This gives us two solutions:

[tex]\[ x = \frac{-2 + 18}{2} = \frac{16}{2} = 8 \]\[ x = \frac{-2 - 18}{2} = \frac{-20}{2} = -10 \][/tex]

So, the two pairs of consecutive even integers are  [tex]\( 8 \) and \( 10 \), or \( -10 \) and \( -8 \).[/tex]

Therefore, the integers are [tex]\( 8 \) and \( 10 \), or \( -10 \) and \( -8 \).[/tex]

Area of a square with sides of length 1/3 yard .
how did you get 1/9

Answers

You are correct.  The area of a square with side lengths of 1/3 yard is 1/9 yd^2.

To get this answer, you muse use the formula for finding the area of a square, which is s^2, where s represents the value of a side length.

The value of the side length in this case is 1/3 yard, so we should substitute that value in for s.

When we do this, we get the following:

A = (1/3 yd)^2 = 1/9 yard^2

Therefore, your answer is 1/9 yd^2.

Answers

Solution: The missing reason in Step 8 is substitution of [tex]x=c\cos (A)[/tex].

Explanation:

The given steps are used to prove the formula for law of cosines.

From step 5 it is noticed that our equation is

[tex]a^2=b^2-2bx+c^2[/tex]      ..... (1)

From step 7 it is noticed that the value of [tex]x[/tex] is [tex]c\cos (A)[/tex].

So by substituting [tex]c\cos (A)[/tex] for [tex]x[/tex] in equation (1) we get the equation of step 8, i.e.,

[tex]a^2=b^2-2bc\cos (A)+c^2[/tex]

Hence, the missing reason in Step 8 is substitution of [tex]x=c\cos (A)[/tex].



Final answer:

The missing reason in Step 8 of the proof for the Law of Cosines is substitution, where x is replaced with cc cos(A) in the expression.

Explanation:

The missing reason in Step 8 of the proof that shows how the Law of Cosines is derived, a2 = b2 + c2 – 2bc cos(A), is the substitution property. In Step 7, we established that c cos(A) is equal to x. Thus, for Step 8, when we replace x with cc cos(A) in the expression b2 – 2bx + c2, we effectively utilize substitution to arrive at the expression a2 = b2 – 2bccos(A) + c2.

Find the area enclosed between f(x)=0.3x2+7 and g(x)=x from x=−4 to x=8.

Answers

First, we sketch a picture to get a sense of the problem. g(x)=x is a diagonal line through (0,0) with slope = = 1. Since we are interested in the area between x = -4 and x = 8, we find the points on the line at these values. These are (-4, -4) and (8,8).

f(x) is a parabola. It's lowest point occurs when x = 0. It is the point (0,7). At x = -4 and x=8 it has the values 11.8 and 26.2 respectively. That is, it contains the points (-4, 11.8) and (8,26.2).

From these we make a rough sketch (see attachment). This is a sketch and mine is very incorrect when it comes to scale but what matters here is which of the curves is on top, which is below and whether they intersect anywhere in the interval, so my rough sketch is good enough. From the sketch we see that f(x) is always above (greater than) g(x).

To find the area between the curves over the given interval we integrate their difference and since f(x) is strictly greater than g(x) we subtract as follows: f(x) - g(x). The limits of integration are the values -4 and 8 (the x-values between which we are looking for the area.

Now let's integrate:
[tex] \int\limits^{8}_ {-4}f(x)-g(x) \, dx = \int\limits^{8}_ {-4}.3 x^{2} +7-x \, dx [/tex]
The integral yields: [tex] [tex](\frac{.3 (8)^{3} }{3} +7(8)- \frac{ (8)^{2} }{2}) -(\frac{.3 (-4)^{3} }{3} +7(-4)- \frac{ (-4)^{2} }{2}) = 117.6[/tex] [/tex]
We evaluate this for 8 and for -4 subtracting the second FROM the first to get:


Final answer:

To find the area enclosed between two functions, we calculate the definite integral of the absolute difference between the functions over the given interval. The area is equal to the integral of ∣f(x) - g(x)∣, split into two parts where g(x) ≥ f(x) and g(x) < f(x), then added together. The enclosed area for the given functions is 82.26 square units.

Explanation:

To find the area enclosed between the functions f(x) = 0.3x^2+7 and g(x) = x from x = -4 to x = 8, we need to calculate the definite integral of the absolute difference between the two functions over the given interval.

The area is equal to the integral of ∣f(x) - g(x)∣ from x = -4 to x = 8. We can split the integral into two parts where g(x) ≥ f(x) and g(x) < f(x), then evaluate each separately. Finally, we add the two areas together.

The area of a rectangular field is 8624 yd^2. If the length of the field is 98 yards, what is its width

Answers

Final answer:

The width of the rectangular field is 88 yards.

Explanation:

To find the width of the rectangular field, we can use the formula for the area of a rectangle: Area = length x width.

In this case, the area is given as 8624 yd² and the length is given as 98 yards. So, we can rearrange the formula to solve for the width: width = Area / length.

Plugging in the values, we have width = 8624 yd² / 98 yds. Dividing these values gives us the width of the field: width = 88 yards.

Your parents have decided to buy a new Toyota 4Runner for 25,635. According to the dealer, the car will depreciate in value approximately $3,000 per year. Write and solve a linear equation to find how many years it will be until the car is worth $3,135

Answers

Let the value of the car be represented by V and the amount of years by y. 
This gives us the following formula:
V = 25,635 - 3000y
(This is because we start with a value of $25,635 and the value decreases by $3,000 every year 'y')

Now, we want to know when the car is worth $3,135, so we know V = 3,135
Now we can make up our equation:
25,365 - 3,000y = 3,135

Collecting terms gives us:
-3,000y = -22,500

Finally we divide by -3,000 to find 'y'
y = -22,500 / -3,000 = 7.5

Hence, the car will be worth $3,135 after 7.5 years.

Jude's interest rate will be 3% for the principal of $1800 on an investment.

What is the simple interest?

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100.

To find Jude's interest rate, we need to set up an equation using the information given. Let R be the interest rate.

The interest earned is equal to the principal times the interest rate, so the equation is:

Interest = Principal × Rate

Substituting the given values, we have:

54 = 1800 × R

Dividing both sides by 1800 gives:

R = 54 / 1800

R = 0.03, or 3%.

Therefore, for an investment of $1800, the interest rate will be 3%.

In MNO NM=3 cm NO=4cm and MO=5 cm list the angels in order from smallest to largest

Answers

Try this explanation:
1. rule: the angle opposite the longest side is the largest, the angle opposite the smallest side it the smallest angle.
2. using the rule: NM<NO<MO, it means that ∠O<∠M<∠N.

The triangle is a right triangle as the sides follow the Pythagorean theorem. The angles opposite the sides are 90° (largest), 53.13°, and 36.87° (smallest), listed from largest to smallest based on side lengths.

The student's question involves a triangle with sides of lengths 3 cm, 4 cm, and 5 cm and asks for the angles to be listed from smallest to largest. Since these side lengths satisfy the Pythagorean theorem (32 + 42 = 52), the triangle is a right triangle, with the right angle opposite the longest side, MO. Using the properties of a right triangle, we can determine that the smallest angle is opposite the shortest side, NM, and the next larger angle is opposite the intermediate side, NO.

To find the actual angle measurements, we would typically use trigonometric ratios such as sine, cosine, or tangent. However, since this is a 3-4-5 triangle, we already know that the angles are 90° for the right angle, and 36.87° and 53.13° for the other two angles, respectively. Thus, the angle opposite NM (3 cm) is the smallest, the angle opposite NO (4 cm) is larger, and the angle opposite MO (5 cm) is the largest, at 90 degrees.

The angle measurements in a right triangle will always follow this pattern based on the lengths of the sides, making it a straightforward matter to list them from smallest to largest.

Three consecutive odd integers whose sum is 243

Answers

Final answer:

The three consecutive odd integers whose sum is 243 are 79, 81, and 83. The integers were found using the algebraic expression for consecutive odd numbers and solving for the sum equal to 243.

Explanation:

To find three consecutive odd integers whose sum is 243, we can represent the first of these integers as 'n', the second as 'n + 2', and the third as 'n + 4', since each consecutive odd integer is 2 more than the previous one. The equation we would use to portray their sum is:

n + (n + 2) + (n + 4) = 243

Simplifying the equation, we combine like terms:

3n + 6 = 243

Next, we subtract 6 from both sides to isolate the 3n term:

3n = 243 - 6

3n = 237

Now we divide by 3 to solve for n:
