I’m thinking of three consecutive odd integers. When I add the larger two the result is nine less than three times the smallest of them. What are the three consecutive odd integers?

The value of CosA is 0.8191

Step-by-step explanation:

Given SinA= 0.5736

We know that [tex]SinA^{2} + CosA^{2} = 1[/tex]

Replacing value of SinA,

[tex](0.5736)^{2} + CosA^{2} = 1[/tex]

[tex](0.3290) + CosA^{2} = 1[/tex]

[tex] CosA^{2} = 1-0.3290[/tex]

[tex] CosA^{2} = 0.6709 [/tex]

[tex] CosA = 0.8191 [/tex]

The value of CosA is 0.8191

Answer:

-12 feet per second

Step-by-step explanation:

average rate of change over [0.75, 1.25] = [tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex]

f(1.25) - f(0.75) = 4 - 10 = -6

1.25 - 0.75 = 0.5

[tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex] = [tex]\frac{-6}{0.5}[/tex] = -12

The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

We have,

To find the average rate of change of the function f(t) over the interval [0.75, 1.25], you can use the following formula:

Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)

Calculate f(1.25):

f(1.25) = -16(1.25)^2 + 20(1.25) + 4

Calculate f(0.75):

f(0.75) = -16(0.75)^2 + 20(0.75) + 4

Plug these values into the formula:

Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)

Calculate the numerator:

Average Rate of Change = [(-16(1.25)^2 + 20(1.25) + 4) - (-16(0.75)^2 + 20(0.75) + 4)] / (1.25 - 0.75)

Simplify the numerator:

Average Rate of Change = [-25 + 25 + 4 - (-9 + 15 + 4)] / (1.25 - 0.75)

Further, simplify:

Average Rate of Change = (4 - (-9 + 15 + 4)) / (1.25 - 0.75)

Continue simplifying:

Average Rate of Change = (4 - 10) / (1.25 - 0.75)

Calculate the final result:

Average Rate of Change = (-6) / (0.5)

Average Rate of Change = -12 feet per second

Thus,

The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

Answer:

A. x + 4

Step-by-step explanation:

f(x) = 4x⁴ − 21x³ − 46x² + 219x + 180

Plug in the zero of each binomial.  If it's also a zero of f(x), then that binomial is a factor of f(x).

f(-4) = 936

f(-3) = 0

f(5) = 0

f(-3/4) = 0

The binomial (x + 4) is not the factor of the polynomial. Then the correct option is A.

The algebraic factors with exactly two terms are known as binomial components. Although binomials are simple to solve and their roots are identical to those of polynomials, binomial factors are intriguing.

The polynomial is given below.

⇒ 4x⁴ – 21x³ – 46x² + 219x + 180

Let's check all the factors.

If the factor does not satisfy the polynomial, then the binomial is a factor of the polynomial.

For x + 4 = 0, then we have

The value of the polynomial at x = -4, will be

⇒ 4(-4)⁴ – 21(-4)³ – 46(-4)² + 219(-4) + 180

⇒ 4(256) – 21(-64) – 46(16) + 219(-4) + 180

⇒ 1024 + 1344 – 736 – 876 + 180

⇒ 2548 – 1612

⇒ 936

Thus, the binomial (x + 4) is not the factor of the polynomial.

Then the correct option is A.

By proving that triangles DEA and EFB are congruent due to the Side-Angle-Side postulate and demonstrating that AE is parallel to FB as well as AD parallel to BC, we can conclude that EABC is a parallelogram.

To prove that quadrilateral EABC is a parallelogram, we can use the properties of triangles and the definition of a parallelogram. According to the given information, E is the midpoint of DA and F is the midpoint of DB. Additionally, we know that E, F, and C are collinear and that FC is congruent to EF.

Leveraging these pieces of information, we observe that triangle DEA is congruent to triangle EFB because they have a side (EF or DE), an angle (at point E, since DE is an extension of EF), and another side (EA or FB, which are halves of DA and DB, respectively) in common (Side-Angle-Side postulate).

Since the two triangles are congruent, angle DEA is congruent to angle EFB, and angle DAE is congruent to angle FEB. These congruent angles imply that line AE is parallel to line BF. Since E and F are midpoints, AE is half of DA and BF is half of DB. If we continue the line AE to meet CD at point A and the line BF to meet CD at point B, EA will be parallel to FB, and AD will be parallel to BC, meeting the definition of a parallelogram.

EABC is a parallelogram because opposite sides are parallel and equal due to the Midpoint Theorem.

Given:

E - midpoint of DA

F - midpoint of DB

E, F, C collinear, FC ≅ EF

To Prove: EABC is a parallelogram.

Proof:

1. By the Midpoint Theorem, EF || AB and EF = 1/2 * AB. (Midpoint Theorem)

2. Since E, F, C are collinear and FC ≅ EF, EC bisects EF at C. Therefore, AB || EC. (Definition of a parallelogram)

3. Since E is the midpoint of DA and C is the midpoint of EF, EC = 1/2 * DA. Since DA = AB, EC = 1/2 * AB. Similarly, EF = 1/2 * AB. Hence, EC = EF. Therefore, EA || BC. (Midpoint Theorem)

4. Since E is the midpoint of DA and C is the midpoint of EF, EC = 1/2 * DA. Since DA = BC, EC = 1/2 * BC. Similarly, EF = 1/2 * BC. Hence, EC = EF. Therefore, EB ≅ AC. (Midpoint Theorem)

Therefore, EABC is a parallelogram.

Step-by-step explanation:

Given: Three boards with measurement  24, 36, and 42 inches.

For the longest length of board we have to find out the H.C.F.

And for H.C.F. we will find out the factors,

[tex]24=2\times2\times2\times3\\36=2\times2\times3\times3\\42=2\times3\times7[/tex]

Here 2 and 3 is the common factor of given length of boards.

So the H.C.F. is 6.

Hence the longest length of board that carpenter can cut is 6 inches.

Answer:

The exponential function is [tex]C(t)=y(b)^t\ Or\ C(t)=1800(1.15)^1[/tex]

Step-by-step explanation:

Given

[tex]t[/tex] be the number of hours.

[tex]y[/tex] number of bacteria cells.

And we know that an exponential function is [tex]C(t)=y(b)^t[/tex],where [tex]b[/tex] is a positive real number, and in which the argument [tex]t[/tex] occurs as an exponent

The petri dish has [tex]1800[/tex] bacteria cells we can say that [tex]y=1800[/tex]

In the equation as [tex]C[/tex] is function of  time and [tex](t)[/tex] will vary as [tex]1,2,3[/tex] for respective hours.

To find the value of [tex]b[/tex] we have to understand that it is dependent on percent increase if there is increment of [tex]15\%[/tex] then [tex]b=1+15\%=1+\frac{15}{100}=1+0.15=1.15[/tex]

So the exponential function will be [tex]C(t)=y(b)^t[/tex] ,plugging the values it will be equivalent to [tex]C(t)=1800(1+0.15)^1[/tex]

Check:

[tex]15\% of 1800 =0.15\times 1800=270[/tex]

So in first hour the cells will increased by a quantity of [tex]270[/tex] cells.

The number of cells after an hour in the petri dish [tex]=(1800+270)=2070[/tex]

That can also be from the formula.

[tex]C(t)=1800(1.15)^1=2070[/tex]

So the exponential function is [tex]C(t)=y(b)^t\ Or\ C(t)=1800(1.15)^1[/tex]

[tex]y[/tex] will increase exponentially as the value of [tex]t[/tex] increase.

Final answer:

The exponential function to represent the growth of bacteria cells, y, after t hours with an initial amount of 1800 cells and a 15% hourly growth rate is y = 1800(1 + 0.15)^t.

Explanation:

To write an exponential function showing the relationship between the number of bacteria cells, y, and the time in hours, t, we begin by using the initial value of 1800 bacteria cells and apply a 15% increase each hour. The exponential growth formula is given by y = P(1 + r)^t, where P is the initial amount, r is the growth rate (expressed as a decimal), and t is the time.

Since the growth rate is 15%, we convert this to a decimal by dividing by 100, resulting in 0.15. The formula to model this bacterial growth would be y = 1800(1 + 0.15)^t. Therefore, for any given number of hours t, you can calculate the number of bacteria cells y.

Time = t = 2 hours and 15 minutes

Converting time into fraction

Time = 2.25 hours

We know that

[tex]s = \frac{d}{t}\\d = s * t\\d = 55 * 2.25\\d = 123.75\ miles[/tex]

So the distance is 123.75 miles

The car travels 25 miles per gallon

We have to calculate the total number of gallon first

So,

So the total amount is:

[tex]2.75*4.95\\= 13.6125\ dollars[/tex]

Total amount is $13.6125. Dividing it by total distance will give us the cost of each mile

So,[tex]Cost\ of\ mile = \frac{Total\ amount}{Distance}\\= \frac{13.6125}{123.75}\\=0.11\ dollars[/tex]

Hence,

Dustin spends $13.6125 on going to work daily. It is 0.11 dollars per mile

Leo has 2574 red marbles.

Let's say that the number of blue marbles Leo has is x. According to the given information, Leo has 9 times as many red marbles as blue marbles. So the number of red marbles Leo has is 9x.

It is also given that he has 2288 more red marbles than blue marbles, which means 9x = x + 2288.

Simplifying the equation, we can subtract x from both sides: 8x = 2288. Dividing both sides by 8, we find that x = 286.

Therefore, Leo has 9 times 286 red marbles, which equals 2574 red marbles.

Final answer:

The price of the less expensive piece of equipment is $1575. This was calculated by setting up an equation based on the total cost and the difference in price between the two pieces of equipment and then solving for the unknown price.

Explanation:

To find the price of the less expensive piece of equipment, we will first assign variables to the two pieces of equipment. Let's call the cost of the less expensive piece of equipment x dollars. Since the other piece cost $850 more, the cost of the second piece would then be x + $850. We are given that the total cost of both pieces is $4000, so we can set up the following equation to represent this relationship:

x + (x + $850) = $4000

To solve for x, we combine like terms and get:

2x + $850 = $4000

Subtracting $850 from both sides gives us:

2x = $3150

Dividing both sides by 2, we find the value of x:

x = $1575

Therefore, the price of the less expensive piece of equipment is $1575.
