Answer: We can use the Pythagorean theorem to solve for the length of the wire. Let's call the length of the wire "x". Then:

x^2 = 26^2 + 8^2

x^2 = 676 + 64

x^2 = 740

x = sqrt(740)

x ≈ 27.2

Therefore, the length of the wire to the nearest tenth of a meter is 27.2 meters.

same slopes: 2. different y-intercepts: (0,-2) and (0,-1.5)

Step-by-step explanation:

First, lets convert both of those to slope intercept form: y = mx + b, where m is the slope and b is the y-intercept.

4x-2y=4 simplifies to -2y=-4x+4, which is y=2x-2

-4x+2y=-3 simplifies to 2y=4x-3, which is y=2x-1.5

this means that they have the same slopes, 2.

they have different y-intercepts. the first one's is (0,-2) and the second one's is (0,-1.5)

If you know your turning point form (vertex form) of a quadratic (y = a(x - h)2 + k), k is the y value, so k = -2

In mathematics, an inequality is a non-equal connection that exists between expressions or values. As a result, imbalance relates to inequality. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two points are not equal, the not equal sign is commonly used (). Different inequalities, no matter how small or large, are utilized to calculate contrast values. Many simple inequalities can be solved by modifying its two sides until only the variables remain. But a few factors contribute to inequality: Negative values are divided or added on both sides. Trade off the left and right.

Mrs. A always grills more onions than peppers, so the number of onions grilled (38) must be greater than the number of peppers grilled (38). (x). As a result, the inequality can be used to represent this relationship:

d. The binomial distribution is a discrete probability distribution and the normal distribution is a continuous probability distribution.

What is binomial distribution?

In probability theory and statistics, the binomial distribution is the discrete probability distribution that gives only two possible results in an experiment, either Success or Failure. For example, if we toss a coin, there could be only two possible outcomes: heads or tails, and if any test is taken, then there could be only two results: pass or fail. This distribution is also called a binomial probability distribution.

The binomial distribution is a discrete probability distribution that models the number of successes in a fixed number of independent trials, where each trial can result in only two outcomes (success or failure), and the probability of success is constant. Examples of situations that can be modeled by a binomial distribution include flipping a coin a fixed number of times or counting the number of defective items in a batch of products.

The normal distribution, on the other hand, is a continuous probability distribution that is often used to model naturally occurring phenomena, such as heights, weights, and test scores. The normal distribution is characterized by a bell-shaped curve, and it is used because many phenomena in nature follow a normal distribution pattern.

So, the binomial and normal distributions are both widely used in probability and statistics, but they are fundamentally different types of distributions.

Answer: 1.465 : 1

Step-by-step explanation:

Slope of the line segment:

m = (5 - 3)/(4 - (-2)) = 2/6 = 1/3

The equation of the line which the line segment lies on is found by:

(y - 3)/(x - (-2)) = 1/3

(y - 3)/(x + 2) = 1/3

(y - 3)/(x + 2) * (x + 2) = 1/3 * (x + 2)

y - 3 = (x + 2)/3 = 1/3 x + 2/3

y = 1/3 x + 11/3

The equation of the line given:

4x + 5y = 21

5y = -4x + 21

y = -4/5 * x + 21/5

Set them equal to each other and solve for x to find their intersection:

1/3 x + 11/3 = -4/5 * x + 21/5

15(1/3 x + 11/3) = 15(-4/5 * x + 21/5)

5 x + 55 = -12 x + 63

17x = 8

x = 8/17

y = 1/3 (8/17) + 11/3 = 8/51 + 181/51 = 189/51

Point (8/17, 189/51)

Distance from right end of segment to intersection:

s = SQRT((4 - 8/17)^2 + (5 - 189/51)^2) = SQRT((60/17)^2 + (66/51)^2) = 3.759

length of segment = SQRT((5–3)^2 + (4 - (-2))^2) = SQRT(4 + 36) = SQRT(40) = 6.324

Distance from the left end to interseciton:

6.324 - 3.759 = 2.555

Ratio of right end to left end:

3.759/2.565 = 1.465

Answer:

The height is 9.73 cm.

Step-by-step explanation:

We can start by finding the radius of the cylinder:

r = d/2 = 4/2 = 2 cm

Then, we can use the formula for the surface area of a cylinder to solve for the height:

SA = 2πrh + 2πr²

130 = 2π(2)(h) + 2π(2)²

130 = 4πh + 8π

122 = 4πh

h ≈ 9.73 cm (rounded to the nearest hundredth)

So the height of the can is approximately 9.73 cm.

We may conclude after answering the provided question that angles NM = 10 + 6 = 16 (as seen in the figure) m JML = 60 - x m KML = 120 m

An angle is a form in Euclidean geometry that is made up of two rays that meet at a point in the centre known as the angle's vertex. Two rays may combine to form an angle in the plane where they are situated. When two planes intersect, an angle is generated. They are referred to as dihedral angles. An angle in plane geometry is a potential configuration of two radiations or lines that represent a termination. The word "angle" comes from the Latin word "angulus," which meaning "horn." The vertex is the place where the two rays, also known as the angle's sides, meet.

Let x be the angle JML measurement. Next, using the angle connections we discovered earlier:

m LKN = x m KML = m LMN = 180 minus x (since they form a linear pair with angle JML)

180 - x - (180 - m LKN) m JML

JML m = LKN m - x

JML = 60 - x KML = m LMN = 180 - 60 = 120 F

JMN = JML (alternative interior angles) KMN = KML (alternate interior angles) m JMN + KMN + m N = 180 (angles in a triangle)

m JMN = 60 x m KMN = 120 60 x + 120 + m N = 180 m N = x

As a result, we have:

LK + KL = NM (segment addition postulate)

NM = 10 + 6 = 16 (as seen in the figure) m JML = 60 - x m KML = 120 m

The manager predicts that Carlos and Jacob need to work 35 hours each to earn the same amount of money.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

We can solve the equation 2,000x + 6,000 = 3,500x - 39,000 as follows:

2,000x + 6,000 = 3,500x - 39,000

Subtracting 2,000x from both sides, we get:

6,000 = 1,500x - 39,000

Adding 39,000 to both sides, we get:

45,000 = 1,500x

Dividing both sides by 1,500, we get:

x = 30

Therefore, the solution to the equation 2,000x + 6,000 = 3,500x - 39,000 is x = 30.

To find the actual number of hours that Carlos and Jacob need to work to earn the same amount of money, we can plug in x = 35 into both of their income expressions and set them equal to each other:

2,000(35) + 6,000 = 3,500(35) - 39,000

Simplifying, we get:

76,000 = 76,000

This means they will earn the same amount of money if they each work 35 hours per week.

Therefore, the manager predicts that Carlos and Jacob need to work 35 hours each to earn the same amount of money.

The average rate of change of the quadratic function f(x) on the interval [0, 15] is equal to 23.

In Mathematics, the average rate of change of a function f(x) on a closed interval [a, b] can be determined by using this mathematical equation (formula):

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f(x) over the interval [0, 15]:

a = 0; f(a) = -x² + 8x + 20

f(0) = -0² + 8(0) + 20

f(0) = 20

b = 9; f(b) = 365

f(15) = -15² + 8(15) + 20

f(15) = 365

By substituting the parameters into the average rate of change formula, we have the following;

Average rate of change = (365 - 20)/(15 - 0)

b. Total revenue is maximized at q ≈ 1354.00.

The demand function is: q = 40,600 - 9p^2

a. To find the elasticity of demand, we need to differentiate the demand function with respect to p and then multiply by p/q:

dq/dp = -18p

(p/q) * (dq/dp) = (-18p/q)

Then, we can substitute p = 2000 and q = 22,400 (the values given in a previous question) into this expression:

E = (-18(2000)/22400) = -1.607

b. Total revenue is maximized where the demand is unit elastic (E = -1). We can set the expression for E equal to -1 and solve for p to find the corresponding value of q:

-1 = (-18p/q)

q = 18p

Substituting the demand function into this expression and simplifying, we get:

q = 40,600 - 9p² = 18p

Rearranging and solving for p, we get:

9p² + 18p - 40,600 = 0

Using the quadratic formula, we get:

p = (-18 ± √(18² - 4(9)(-40,600)))/(2(9)) ≈ 75.22 or -227.22

Since the price must be positive, the only valid solution is p ≈ 75.22. Substituting this back into the demand function, we get:
