Which equation describes a line graphed above?

Answer:

yes, it is true because a supplimentary angle is 180 degrees and if their is an acute angle then it is less than 90 degrees which means you subtract that by 180 and you get a number over 90 and an obtuse angle is over 90 which means the other side of the acute angle is obtuse. And the suppliment to an acute angle is always over 90 degrees

Answer:

R(t)=10+0.50t

Step-by-step explanation:

Let t be the number of years.

We have been given that When Joseph first starts working at a grocery store, his hourly rate is $10.

 For each year he works at the grocery store, his hourly rate increases by $0.50.

So the hourly rates after t years will be 10 plus 0.50t.We can represent this information in an equation as: R(t)=10+0.50t

Therefore, the function  R(t)=10+0.50t represents Joseph's hourly rates after t years.

Answer:

x = 6

Step-by-step explanation:

If A, B and C lies on a straight line in order, then;

AB+BC = AC

x+12+2x-4 = 26

x+2x+12-4 =26

3x+8 = 26

3x = 26-8

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

Answer:

12 times

Step-by-step explanation:

1 quart = 32 ounces

3 quart = x

x = 3 × 32 ounces

x = 96 ounces

The number of times of he need to fill an 8-ounce measuring cup to fill the pot is calculated as:

= 96 ounces/8 ounces measuring cup

= 12 times

Therefore, Alan needs to fill an 8 ounce measuring cup 12 times in order to fill the pot of soup.

The ratio 40 minutes to 70 minutes can be written as 4/7 in lowest terms.

To understand how we arrived at the fraction 4/7, let's break down the process of simplifying the given ratio.

Step 1: Write the ratio as a fraction

The ratio 40 minutes to 70 minutes can be expressed as a fraction: 40/70.

Step 2: Find the greatest common divisor (GCD)

To simplify the fraction, we need to determine the GCD of the numerator (40) and the denominator (70). The GCD is the largest number that evenly divides both numbers. In this case, the GCD of 40 and 70 is 10.

Step 3: Divide by the GCD

We divide both the numerator and denominator of the fraction by the GCD (10). Dividing 40 by 10 gives us 4, and dividing 70 by 10 gives us 7.

Therefore, the simplified fraction is 4/7, which represents the ratio of 40 minutes to 70 minutes in its lowest terms.

Simplifying fractions is a fundamental concept in mathematics that involves reducing fractions to their simplest form. By dividing both the numerator and denominator by their GCD, we eliminate any common factors and obtain a fraction that cannot be further simplified.

This process allows us to express ratios and proportions in their most concise and understandable form.

Step-by-step explanation:

The area of the rectangle in terms of b is 11b - b², and the perimeter is always 22, regardless of the value of b.

A rectangle is a four-sided flat shape with opposite sides that are equal in length and parallel to each other. It has four right angles (90-degree angles) at each corner. The two sides that are parallel to each other are called the length, and the other two sides are called the width.

The area of a rectangle is found by multiplying its length and width, and its perimeter is the sum of the lengths of all four sides. Rectangles are common in everyday life and can be found in many different contexts, such as books, doors, windows, and electronic screens.

According to given information,

Let's assume that the length of the rectangle is 'l' and the width is 'b'.

The area of a rectangle is given by the formula A = lb, where A is the area, l is the length, and b is the width.

The perimeter of a rectangle is given by the formula P = 2(l + b), where P is the perimeter, l is the length, and b is the width.

So, the area of the rectangle is:

A = lb = 28

And the perimeter of the rectangle is:

P = 2(l + b) = 40

P = (l+b) = 20

l= 20 -b

Now, we can substitute l = 20 - b into these formulas:

A = (20 - b)b

P = 2(20 - b + b)

Simplifying, we get:

A = 40b - b²

P= 40

So, the area of the rectangle in terms of b is 11b - b², and the perimeter is always 22, regardless of the value of b.

The length of the rectangle is 10 cm and breadth of the rectangle is 4 cm.

What is rectangle?

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

The longer parallel sides are called length(l) and two shorter sides are called breadth(b).

Perimeter of a rectangle is 2(l+b).

Area of rectangle is l*b.

2(l+b)=28

L+b=28/2=14

L=14-b .....eq(1)

L*b=40

(14-b)b=40

14b-b^2=40

b^2-14b+40=0

b^2-10b-4b+40=0

b(b-10)-4(b-10)=0

(b-10)(b-4)=0

Either b=10 or b=4

If b=10 then l =4 but length can't be shorter than the breadth so b=4cm and l=10 cm is the answer.

The required equation for the length of the candle is L = 9-0.75t.

Given that a 9-inch candle burns at the rate of 0.75 in per hour we need to determine the equation for the length L of the candle when it burns for t hours,

So, if the candle is burning at the rate of 0.75 in per hour so after burning for t hour the length decreases by 0.75t, from the original length i.e 9 in

So, we can write the equation as =

L = 9-0.75t

Hence the required equation for the length of the candle is L = 9-0.75t.

The function f(x, y) satisfies the conditions that its limit approaches zero as x approaches zero along two different paths: y = x and y = x^2. This implies that as x approaches zero, the function f(x, y) must approach zero regardless of whether y varies linearly or quadratically with x.

The given conditions state that the limit of f(x, y) as x approaches zero along the path y = x is zero. This means that as x gets arbitrarily close to zero, the function f(x, y) approaches zero when y varies linearly with x. Similarly, the second condition states that the limit of f(x, y) as x approaches zero along the path y = x^2 is also zero. This implies that when y varies quadratically with x, the function f(x, y) still approaches zero as x approaches zero. Therefore, the function f(x, y) must satisfy both conditions by converging to zero as x approaches zero along both paths.

Answer:

Step-by-step explanation:

To find the indefinite integral ∫(x^6) dx by making a change of variables, we can let u = x^7. Then, we can express dx in terms of du using differentiation.

Differentiating both sides of the equation u = x^7 with respect to x, we get:

du/dx = 7x^6

dx = du / 7x^6

Substituting dx in terms of du in the integral, we have:

∫(x^6) dx = ∫(x^6) (du / 7x^6)

Simplifying the expression, the x^6 terms cancel out:

∫(x^6) dx = ∫(1 / 7) du

Now we can integrate with respect to u:

∫(1 / 7) du = (1/7) ∫ du

The indefinite integral of du is simply u, so we have:

(1/7) ∫ du = (1/7) u + c

Finally, substituting u back in terms of x, we get:

(1/7) u + c = (1/7) (x^7) + c

Therefore, the indefinite integral of x^6 dx, with the change of variables, is (1/7) (x^7) + c, where c represents the constant of integration.

The option that would decrease the margin of error is B. increasing the sample size.

The margin of error is a statistic that expresses the amount of random sampling error in survey results. The greater the margin of error, the less confident one should be that a poll result will accurately reflect the results of a population census.

Because the sample size is in the denominator of the margin of error calculation, increasing the sample size reduces the margin of error. Furthermore, by expressing a value in a range, the margin of error assists researchers in determining its accuracy.

The margin of error for a 99% confidence interval estimate is approximately 0.0838 or 8.38%.

To calculate the margin of error for a 99% confidence interval estimate, we can use the formula:

Margin of Error = Z * sqrt(p_hat * (1 - p_hat) / n)

Where:

Z is the z-value corresponding to the desired confidence level (99% confidence level corresponds to a z-value of approximately 2.576).

p_hat is the sample proportion (percentage of apples with bruises), which is calculated as the number of apples with bruises divided by the total sample size.

n is the sample size.

Given:

Sample size (n) = 100

Number of apples with bruises = 12

Calculating the sample proportion:

p_hat = 12 / 100 = 0.12

Using the z-value for a 99% confidence level (z = 2.576), we can calculate the margin of error:

Margin of Error = 2.576 * sqrt(0.12 * (1 - 0.12) / 100)

Calculating the margin of error:

Margin of Error = 2.576 * sqrt(0.12 * 0.88 / 100)

Margin of Error = 2.576 * sqrt(0.1056 / 100)

Margin of Error = 2.576 * sqrt(0.001056)

Margin of Error ≈ 2.576 * 0.0325

Margin of Error ≈ 0.0838

Therefore, the margin of error for a 99% confidence interval estimate is approximately 0.0838 or 8.38%.
