Are the below pairs of lines parallel, perpendicular, or neither?
9x+12y = 8 and 6x+8y = −1

Parallel

Perpendicular

Neither

Answers

Answer 1
They are parallel to eachother

Answer 2
9x + 12y = 8
12y = -9x + 8
y = - 3/4x + 2/3....slope here is -3/4, y int is 2/3

6x + 8y = -1
8y = -6x - 1
y = - 3/4x - 1/8...slope here is -3/4, y int is -1/8

same slope, different y intercepts means parallel lines

Given ONL=MLN, O and M are right angles prove LM=NO

Answers

Final answer:

Using the properties of Isosceles triangles and right-angled triangles, it can be deduced that LM = NO given that angles ONL = MLN and O and M are right angles.

Explanation:

The given question is about proving equivalency of lines in a geometric figure. Given the figure has the angles ONL and MLN that are equal and O and M are right angles. Given these conditions, using the properties of triangles especially the Isosceles Triangle (where two sides are equal), we can conclude that LM = NO.

To prove this assumption, we incorporate the following facts: In an isosceles triangle, the angles opposite to equal sides are equal. Hence, if ONL = MLN, it implies that NO = LM. Additionally, if angles O and M are right angles, it signifies that the triangles formed are right angled triangles. Therefore, using the property of isosceles right angled triangles, the sides opposite to equal angles are equal.

Based on these facts and the properties of geometric concepts [Isosceles Triangle, Pythagorean theorem and right angled triangles], we can confidently conclude that LM = NO. This proves that given the conditions in the problem, the lines LM and NO are equal in length.

Final answer:

Given that ONL=MLN and O and M are right angles, we can say that triangles ONL and MLN are congruent right-angled triangles. Therefore, according to the property of congruent triangles, the sides opposite the equal angles in these triangles (i.e., LM and NO) should also be equal to each other.

Explanation:

The question involves proving the equivalence of two lines in a geometric configuration, LM and NO, where two angles, ONL and MLN, are given as equal and O and M are right angles. This is quite a typical problem in Geometric Proof, an important topic in High School Mathematics.

To solve this, we need to apply the properties of triangles and the concept of congruent triangles. Since ONL and MLN are given as equal angles and O and M are right angles, we know that triangle ONL and MLN are right-angled triangles. In a right-angled triangle, if one angle is equal, then the other angles will be equal because the summing of angles in a triangle is 180 degrees.

Because we have now two right-angled triangles with their respective angles equal (ONL = MLN and NOM = LNM), they must be congruent triangles by the Angle-Angle (AA) criterion for congruency. This implies that the sides opposite the equal angles in these two triangles should also be equal. So, LM = NO in these triangles.

C write function distance that calculates the distance between two points (x1, y1) and (x2, y2). all numbers and return values should be of type double.

Answers

Your question is unclear but here is my try.

Given (0, 5) and (5, 0), find the distance between the two points.

Let (0, 5) and (5, 0) be the two points.

Let d = distance

d = sqrt{(5 - 0)^2 + (0 - 5)^2}

d = sqrt{(5)^2 + (-5)^2}

d = sqrt{25 + 25}

d = sqrt{50}

d = sqrt{25}•sqrt{2}

d = 5•sqrt{2}

1250 is deposited in an account that pays 6.5% annual interst compounded continuosly. what is the balance after 8years?

Answers

This is an exponential growth/decay problem. 

So, we use the formula y=ab^x.
1250 is what you started out with, so it is your initial value. 

We have to change the percentile to a decimal, so we will move the decimal two places to the left, making it 0.065. We see in the problem that the word "compounded" is brought up, implying an increase. Therefore, 0.065 will be added by 1 to get 1.065. You place that value into the parentheses. 

The x represents the amount of time, which is 8 years. 

So, 1250(1.065)^8 = 2,069 (answer was 2068.74 before being rounded).

Find the height of the pole if the shadow of a boy 6 ft. tall is 3 ft. and the shadow of the pole is 2 1/3 yards. 1 yards 4 feet 14 feet

Answers

Hi there! To solve this question, we can write and solve a proportion. We put shadow/height = shadow/x. We do this, because we're looking for the height of the pole and we already know the how big the shadow of the pole is. The yards need to be converted to feet. There are 3 feet in one yard and 3 * 7/3 is 21/3 or 7 in simplest form. The pole casts a shadow 7 feet tall. Plug in the numbers like this: 3/6 = 7/x. Cross multiply the values in order to get 3x = 42. now, you divide each side by 3 to isolate the "x". When you, you get x = 14. There. The height of the pole is 14 feet. The answer is C: 14 feet.

According to a survey, 75% of adults in the united states think the u. s. government system is broken. of these 75%, about 7 out of 10 think that the government can be fixed.
a.find the probability that a randomly selected adult thinks the u. s. government system is broken and thinks the government can be fixed.
b.given that a randomly selected adult thinks the u. s. government system is broken, find the probability that he or she thinks the government cannot be fixed.

Answers

1.       Probability that a randomly selected adult thinks the U.S. government system is broken and can be fixed:

P (A and B) = P (A) * P (B|A) = .75 * .7 = 0.525

2.       Probability that given that a randomly selected adult thinks the U.S. government system, he or she thinks the government cannot be fixed.

P (B|A) = (1 – P (B|A) = 3/10 = 0.3

To calculate the probability that an adult thinks the U.S. government is broken and can be fixed, multiply 75% by 70%, resulting in 52.5%. The probability that an adult thinks the government is broken but can't be fixed is found by subtracting 70% from 100%, yielding 30%.

The subject in question pertains to probability and statistics, which involves calculating the likelihood of certain outcomes based on given data and constructing confidence intervals to understand the population parameters.

Part A:

To find the probability that a randomly selected adult thinks the U.S. government system is broken and thinks the government can be fixed, we multiply the two given probabilities: 75% of adults think the system is broken and, of these, 70% think it can be fixed. Therefore:
0.75 (probability of thinking the system is broken) × 0.70 (probability of thinking it can be fixed given the system is broken) = 0.525 or 52.5%.

Part B:

Given that an adult thinks the government system is broken, to find the probability that they think it cannot be fixed, we subtract the probability that they think it can be fixed from 1:
1 - 0.70 = 0.30 or 30%.

What is an angle?

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

Given that Angle XYZ is congruent to angle AOB, therefore, we can write,

∠XYZ ≅ ∠AOB

Also, it is mentioned that Angle AOB is congruent to angle WYT, Therefore, we can write,

∠AOB ≅ ∠WYT

Now, we can write the two congruency together as,

∠XYZ ≅ ∠AOB ≅ ∠WYT

∠XYZ ≅ ∠WYT

Hence, the correct option is C, ∠XYZ ≅ ∠WYT.

What are the x-intercepts of the graph of the function f(x)=x2-16x+64

Answers

Final answer:

To find the x-intercepts of the function f(x) = x^2 - 16x + 64, we set f(x) to zero and solve for x. The quadratic factors to (x - 8)^2 = 0, revealing that the graph has a single x-intercept at x = 8.

Explanation:

To determine the x-intercepts of the graph of the function f(x) = x^2 - 16x + 64, we need to find the values of x for which f(x) equals zero. This involves solving the quadratic equation, x^2 - 16x + 64 = 0.

One approach is to factor this equation if possible. Another approach is to use the quadratic formula.

The given quadratic equation can be factored as (x - 8)^2 = 0.

Therefore, the only solution to this equation is x = 8, which means the graph of the function touches the x-axis at this point and has a vertex at (8, 0), making the x-intercept of the graph equal to 8.

The factored form indicates that the function has a double root at x = 8, which means the parabola touches and then bounces off the x-axis at this point.

Thus, rather than crossing the x-axis at two distinct points, the parabola has a single x-intercept at x = 8. This is often referred to as a repeated or double root because the solution appears twice when the quadratic is factored.
