Answer:

Step-by-step explanation:

The required inequality x + m ≤ 510, and the distance is 316 miles.

Inequity occurs when two phrases are joined by a sign such as "not equal to," "more than," or "less than." The inequality illustrates the larger than and less than the relationship between variables and numbers.

Given that Mr. Estrada's car can only drive 510 miles on a full tank of petrol. He drove the car 194 miles after filling up the tank with gasoline.

Let,

x miles = distance already traveled

m miles = distance miles can travel with remaining gas

510 = max. miles can travel on a full tank

As per the given question,

The inequality will be written as,

x + m ≤ 510

194 + m ≤ 510

m ≤ 510 - 194

Apply the subtraction operation, and we get

m ≤ 316

Therefore, the required inequality x + m ≤ 510, and the distance is 316 miles.

Answer:

Option (1)

Step-by-step explanation:

The given expression is,

\(\frac{x^{2}-19x+90}{x^{2}+19x+90}\) ÷ \(\frac{x^{2}-2x-80}{x^{2}-x-72}\)

Now we will factor each polynomial separately and substitute the factors in the expression.

x² - 19x + 90 = x² - 10x - 9x + 90

                    = x(x - 10) - 9(x - 10)

                    = (x - 10)(x - 9)

x² - 2x - 80 = x² - 10x + 8x - 80

                  = x(x - 10) + 8(x - 10)

                  = (x + 8)(x - 10)

x²- x - 72 = x² - 9x + 8x - 72

               = x(x - 9) + 8(x - 9)

               = (x + 8)(x - 9)

x² + 19x + 90 = x² + 10x + 9x + 90

                      = x(x + 10) + 9(x + 10)

                      = (x + 9)(x + 10)

Now by substituting these factors in the given expression

\(\frac{(x - 10)(x - 9)}{(x + 10)(x + 9)}\) ÷ \(\frac{(x + 8)(x - 10)}{(x + 8)(x - 9)}\) = \(\frac{(x - 10)(x - 9)}{(x + 10)(x + 9)}\) ÷ \(\frac{(x - 10)}{(x - 9)}\)

                                     = \(\frac{(x - 10)(x - 9)}{(x + 10)(x + 9)}\) × \(\frac{(x - 9)}{(x - 10)}\)

                                     = \(\frac{(x - 9)^2}{(x + 10)(x + 9)}\)

Therefore, Option (1) will be the answer.

The probability that the sample mean will be greater than 57.95 is 0.0495.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. This is the basic probability theory, which is also used in the probability distribution.

To solve this question, we need to know the concepts of the normal probability distribution and of the central limit theorem.

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z=\dfrac{X-\mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The Central Limit Theorem establishes that, for a random variable X, with mean \(\mu\) and standard deviation \(\sigma\), a large sample size can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(\frac{\sigma}{\sqrt{\text{n}} }\).

In this problem, we have that:

The probability that the sample mean will be greater than 57.95

This is 1 subtracted by the p-value of Z when X = 57.95. So

\(Z=\dfrac{X-\mu}{\sigma}\)

By the Central Limit Theorem

\(Z=\dfrac{X-\mu}{\text{s}}\)

\(Z=\dfrac{57.95-53}{3}\)

\(Z=1.65\)

\(Z=1.65\) has a p-value of 0.9505.

Therefore, the probability that the sample mean will be greater than 57.95 is 1-0.9505 = 0.0495

Answer:

\(h>11\)

Step-by-step explanation:

We have the inequality:

\(-2(h-5)<-12\)

Solve. Divide both sides by -2. Since we are dividing by a negative, we must flip the inequality sign. Thus:

\(h-5>6\)

Add 5 to both sides:

\(h>11\)

Therefore, our solution is all numbers greater than 11 .

This means that if we substitute any number greater than 11 into our original inequality, the inequality will be true.

The speed of the 10 g bullet was approximately 1.732 m/s. This can be answered by the concept of conservation of momentum.

To find the speed of the 10 g bullet, we can use the conservation of momentum and the potential energy stored in the spring. The initial momentum of the bullet-block system is equal to the final momentum after the bullet embeds itself in the block, and the potential energy in the spring equals the initial kinetic energy of the bullet-block system.

1. Convert the bullet mass to kg: 10 g = 0.01 kg
2. Convert the compression of the spring to meters: 45 cm = 0.45 m

First, find the potential energy stored in the spring when it is compressed by 0.45 m:
PE_spring = 0.5 × k × x²
PE_spring = 0.5 × 55 N/m × (0.45 m)²
PE_spring = 6.06875 J

Now, equate the potential energy to the initial kinetic energy of the bullet-block system:
KE_initial = PE_spring

Since KE = 0.5 × m × v², we can write:
0.5 × (0.01 kg + 2.0 kg) × v² = 6.06875 J

Solve for v (bullet's speed):
v^2 = (6.06875 J) / (0.5 × (0.01 kg + 2.0 kg))
v^2 = 2.9971
v = 1.732 m/s

So, the speed of the 10 g bullet was approximately 1.732 m/s.

The cost of painting the inside of the open rectangular box at ₦90 per square meter is ₦216.

We have,

To find the cost of painting the inside of the open rectangular box, we need to calculate the surface area of the box and then multiply it by the cost per square meter.

So,

Given the dimensions provided,

Length = 1m

Width = 70cm = 0.7m

Depth = 50cm = 0.5m

To calculate the surface area, we need to consider the four inner faces of the box: the bottom, the front, the back, and the sides.

The area of the bottom face: Length * Width = 1m x 0.7m = 0.7m²

The area of the front face: Length * Depth = 1m x 0.5m = 0.5m²

The area of the back face (same as the front): 0.5m²

The area of the left side face: Width * Depth = 0.7m x 0.5m = 0.35m²

The area of the right side face (same as the left): 0.35m²

To find the total surface area, we sum up all these areas:

Total surface area = bottom + front + back + left + right

= 0.7m² + 0.5m² + 0.5m² + 0.35m² + 0.35m²

= 2.4m²

Now, we can calculate the cost by multiplying the surface area by the cost per square meter:

Cost = Total surface area x Cost per square meter

= 2.4m² x ₦90/m²

= ₦216

Therefore,

The cost of painting the inside of the open rectangular box at ₦90 per square meter is ₦216.

Question 3: True

Question 4: False

Question 5: True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c.

This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

Question 3: If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c.

True

When the derivative of a function, f'(x), is negative at a point c, it indicates that the function is decreasing at that point. Additionally, if the second derivative, f''(x), exists and is negative at x = c, it implies that the graph of f(x) is concave down at that point.

Question 4: A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0.

False

A local extreme point of a polynomial function can occur when f'(x) = 0, but it is not the only condition. A local extreme point can also occur when f'(x) does not exist (such as at a sharp corner or cusp) or when f'(x) is undefined. Therefore, f'(x) being equal to zero is not the sole requirement for a local extreme point to exist.

Question 5: If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = c.

True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c. This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

The parametric equations for the line of intersection are:

x(t) = (-57/10) - (31/10)t, y(t) = t, z(t) = (5/2)t + 17/2, where the parameter t can take any real value.

To find the parametric equations for the line of intersection between the planes, we can solve the system of equations formed by the two planes:

Plane 1: 5x + 3y + 5z = -19 ...(1)

Plane 2: 2z - 5y = 17 ...(2)

To begin, let's solve Equation (2) for z in terms of y:

2z - 5y = 17

2z = 5y + 17

z = (5/2)y + 17/2

Now, we can substitute this expression for z in Equation (1):

5x + 3y + 5((5/2)y + 17/2) = -19

5x + 3y + (25/2)y + (85/2) = -19

5x + (31/2)y + 85/2 = -19

5x + (31/2)y = -19 - 85/2

5x + (31/2)y = -57/2

To obtain the parametric equations, we can choose a parameter t and express x and y in terms of it. Let's set t = y:

5x + (31/2)t = -57/2

Now, we can solve for x:

5x = (-57/2) - (31/2)t

x = (-57/10) - (31/10)t

Therefore, the parametric equations for the line of intersection are:

x(t) = (-57/10) - (31/10)t

y(t) = t

z(t) = (5/2)t + 17/2

The parameter t can take any real value, and it represents points on the line of intersection between the two planes.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is primarily concerned with the study of the six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent, which are defined as ratios of the sides of a right-angled triangle.

We can use the coordinates of the given point to determine the trigonometric ratios of the angle that it lies on.

Let r be the distance from the origin to the point (48, 20), which is given by the Pythagorean theorem:

\(r = \sqrt{(48^2 + 20^2)} = \sqrt{(2304 + 400)} = \sqrt{(2704)} = 52\)

We can then use the coordinates of the point and the value of r to determine the trigonometric ratios:

sin θ = y/r = 20/52 = 5/13

cos θ = x/r = 48/52 = 12/13

tan θ = y/x = 20/48 = 5/12

csc θ = r/y = 52/20 = 13/5

sec θ = r/x = 52/48 = 13/12

cot θ = x/y = 48/20 = 12/5

Therefore, the exact values of the trigonometric ratios are:

sin θ = 5/13

The significance level, account for multiple testing, and recognize the limitations and context when interpreting p-values.

The p-value is a crucial concept in statistical hypothesis testing. It refers to the probability of observing a test statistic as extreme as or more extreme than the one observed, given that the null hypothesis is true.

In other words, it is the probability of obtaining the observed result by chance, assuming that there is no true effect.
There are several key guidelines that researchers need to keep in mind when interpreting p-values.

This threshold should not be taken as a hard-and-fast rule and other factors such as the study design sample size and effect size should also be considered.
Secondly, the p-value alone cannot determine the validity or importance of a research finding.

It is just one piece of evidence that needs to be considered along with other factors, such as the magnitude of the effect, the precision of the estimates, the plausibility of alternative explanations, and the practical implications of the findings.
Thirdly, the p-value can be influenced by various factors, such as the choice of statistical test, the assumptions made about the data, and the presence of outliers or influential observations.

Therefore,

Researchers should always report the assumptions and limitations of their analyses and consider conducting sensitivity analyses to test the robustness of their results.
In summary,

A parking sign is in the shape of a square. The area in square centimeters, is given by the equation: l^(2)=400 The length, l, of one side of the sign is  20 centimeters.

The equation l^2 = 400 represents the relationship between the length of one side of the square (l) and its area. To find the length of one side, we need to solve for l. In this case, we can take the square root of both sides of the equation to isolate l.

Taking the square root of 400, we get l = √400 = 20.

Therefore, the length of one side of the parking sign is 20 centimeters.

By substituting the value of l back into the equation, we can verify that it satisfies the equation: (20)^2 = 400, which is true.

The type of loan that Brady most likely getting  is option (a) conventional loan

Conventional loans are typically not guaranteed or insured by the government and often require a higher down payment compared to government-backed loans such as FHA or VA loans. The down payment requirement of $5,250, which is 3.5% of the purchase price, is lower than the typical down payment requirement for a conventional loan, which is usually around 5% to 20% of the purchase price.

ARM (Adjustable Rate Mortgage) loans have interest rates that can change over time, which can make them riskier for borrowers. FHA (Federal Housing Administration) loans are government-backed loans that typically require a lower down payment than conventional loans, but they also require mortgage insurance premiums.

VA (Veterans Affairs) loans are available only to veterans and offer favorable terms such as no down payment requirement, but not everyone is eligible for them. Fixed-rate loans have a fixed interest rate for the life of the loan, but the down payment amount does not indicate the loan type.
