Answer:

1, -4, 2 + 5i, 2 - 5i

Step-by-step explanation:

First, I factor x^2 + 3x - 4

==> I get: (x - 1) (x +4)

Then, I factor (x^2 - 4x + 29)

==> And I get (2 + 5i) (2 - 5i)

You can use the quadratic formula to factor or use the "X" to solve them.

Hope this help!

Applying the factor theorem, it is found that the roots of the equation are:

[tex]x = 1, x = -4, x = 2 + 5i, x = 2 - 5i[/tex]

The factor theorem states that if [tex]x_1, x_2, ..., x_n[/tex] are roots of a polynomial, it can be written as:

[tex](x - x_1)(x - x_2)...(x - x_n)[/tex]

In this problem:

[tex](x^2 + 3x - 4)(x^2 - 4x + 29) = 0[/tex]

Thus, the roots are the values of x for which either:

[tex]x^2 + 3x - 4 = 0[/tex]

Or

[tex]x^2 - 4x + 29 = 0[/tex]

First, [tex]x^2 + 3x - 4 = 0[/tex]

Which is a quadratic equation with [tex]a = 1, b = 3, c = -4[/tex], thus:

[tex]\Delta = 3^{2} - 4(1)(-4) = 25[/tex]

[tex]x_{1} = \frac{-3 + \sqrt{25}}{2} = 1[/tex]

[tex]x_{2} = \frac{-3 - \sqrt{25}}{2} = -4[/tex]  

Thus, [tex]x = 1[/tex] and [tex]x = -4[/tex] are roots.

Then, we solve [tex]x^2 - 4x + 29 = 0[/tex].

The coefficients are [tex]a = 1, b = -4, c = 29[/tex], so:

[tex]\Delta = (-4)^{2} - 4(1)(29) = -100[/tex]

[tex]x_{1} = \frac{-(-4) + \sqrt{100}}{2} = 2 + 5i[/tex]

[tex]x_{2} = \frac{-(-4) - \sqrt{100}}{2} = 2 - 5i[/tex]

Thus, [tex]x = 2 + 5i[/tex] and [tex]x = 2 - 5i[/tex] are also roots.

Final answer:

The smallest power of 10 that exceeds 999,999,999,991 is 10¹² because 999,999,999,991 is just one less than 1,000,000,000,000, which can be expressed as 10¹² in exponential form.

Explanation:

The question asks for the smallest power of 10 that would exceed 999,999,999,991. Understanding how to convert numbers into their exponential form plays a crucial role here. For a power of 10, the exponent tells you how many zeros you'd add to the digit 1 to express that number in long form. For example, 10² is 100, which is a 1 followed by 2 zeros. In the case of 999,999,999,991, we need to find a power of 10 that is just larger than this number.

Observing the number 999,999,999,991, it is just one less than 1,000,000,000,000. If we were to express 1,000,000,000,000 in exponential form, it would be 10¹², because it is a 1 followed by 12 zeros. Therefore, the smallest power of 10 that exceeds 999,999,999,991 is 10¹². This example illustrates how understanding integer powers and exponential notation is essential in solving problems of this nature effectively.

ANSWER

[tex]7.26451[/tex] correct  to 3 decimal places is [tex]7.265[/tex]

EXPLANATION

We start counting from the first number after the decimal point.

So starting from 2, we count 3 decimal places to the right and land on 4.

Next, we check to see if the number after 4, is greater or equal 5, then we round up, else we round down.

Since that number is 5, it is greater than or equal to 5.

Therefore we round up to obtain [tex]7.265[/tex]

7.264 51 correct to 3 decimal places is 7.265.

What is means to write a number to three decimal places is that after the decimal point, there should be three numbers. It means that the number should be rounded off to the nearest thousandth.

In order to round off to 3 decimal places take the following steps:

Examine the number in the ten thousandth place:

The number in the ten thousandth place is 5, so the number in the thousandth place increases by 1. The number becomes 7.265.

Answer:

Rate of Pratap in still water is 4.5 miles/hour and rate of current is 0.5 miles/hour.

Step-by-step explanation:

Pratap Puri rowed 10 miles down a river in 2 ​hours, but the return trip took him 2.5 hours.

We know that, [tex]Speed = \frac{Distance}{Time}[/tex]

So, the speed of Pratap with the current will be:  [tex](\frac{10}{2})miles/hour = 5[/tex] miles/hour

and the speed of Pratap against the current will be:  [tex](\frac{10}{2.5})miles/hour = 4[/tex] miles/hour.

Suppose, the rate of Pratap in still water is [tex]x[/tex] and the rate of current is [tex]y[/tex].

So, the equations will be........

[tex]x+y= 5 .............................. (1)\\ \\ x-y=4 .............................. (2)[/tex]

Adding equation (1) and (2) , we will get......

[tex]2x=9\\ \\ x=\frac{9}{2}= 4.5[/tex]

Now, plugging this [tex]x=4.5[/tex] into equation (1), we will get.....

[tex]4.5+y=5\\ \\ y=5-4.5 =0.5[/tex]

Thus, Pratap can row at 4.5 miles per hour in still water and the rate of the current is 0.5 miles/hour.

Pratap's rowing speed in still water is 4.5 miles per hour, and the speed of the current is 0.5 miles per hour.

First, we need to understand that Pratap's velocity, or speed, is the sum of his own rowing speed and the speed of the current when he rows downstream, and the difference of his speed and the current when he rows upstream. To find these speeds, we can use the formula for speed, which is distance/time.

When Pratap is rowing downstream (with the current), he covers 10 miles in 2 hours, giving a speed of 10/2 = 5 miles per hour. When rowing upstream (against the current), he covers the same distance in 2.5 hours, giving a speed of 10/2.5 = 4 miles per hour.

Now, if we add these two speeds together and divide by 2, we get the rowing speed of Pratap in still water (since half the time he gets an assist from the current, and half the time he is fighting against it). This is (5+4)/2 = 4.5 miles per hour.

The speed of the current would be the difference between Pratap's rowing speed and the overall speed when he is rowing downstream, which is 5 - 4.5 = "0.5 miles per hour".

Because they want you to round to the nearest 10th and 0 is the ground.

Answer:

Option B. 0.6 seconds

Step-by-step explanation:

As given in the table at time t = 0 the maximum height of the penny is 2 meters.

In simpler way we can say the penny has been throw from a height of 2 meters.

Now this process can be represented by the equation of motion

[tex]h=ut+\frac{1}{2}gt^{2}[/tex]

For free fall u = 0

So [tex]h=\frac{1}{2}gt^{2}[/tex]

where h = 2 meters

and g = 9.81 m/sec²

By putting these values in the equation

[tex]2=\frac{1}{2}(9.81)(t)^{2}=4.905t^{2}[/tex]

[tex]t^{2}=\frac{2}{4.905}=0.4077[/tex]

t = √0.4077 = 0.6385 seconds

or t = 0.6 seconds

Answer is option B. 0.6 seconds

The pen should be built with dimensions of 9 meters by 6 meters, with the wall forming one of the 9-meter sides.

To find the dimensions of the pen that will give the maximum area, we can use the fact that for a given perimeter, a square has the maximum area. Since one side of the pen is formed by a wall, we have 36 meters of fencing for the other three sides. Let's denote the length of the pen as [tex]\( l \)[/tex] and the width. The perimeter  of the three sides that need fencing is given by:

[tex]\[ P = l + 2w \][/tex]

 We know that the total length of the fencing available for these three sides is 36 meters, so:

 [tex]\[ l + 2w = 36 \][/tex]

To maximize the area, we want [tex]\( l \)[/tex] to be as close to [tex]\( w \)[/tex] as possible, which means we want to divide the 36 meters of fencing equally among the three sides. If we let \( w = w \), then the equation becomes:

[tex]\[ l + 2l = 36 \][/tex]

[tex]\[ 3l = 36 \][/tex]

[tex]\[ l = \frac{36}{3} \][/tex]

[tex]\[ l = 12 \][/tex]

However, this would mean that there is no fencing left for the width, as all 36 meters would be used for the length. To avoid this, we need to distribute the fencing so that two of the sides (the widths) are equal and the remaining side (the length) is the third side. To find the maximum area, we set [tex]\( l = 2w \)[/tex], which gives us:

[tex]\[ 2w + 2w = 36 \][/tex]

[tex]\[ 4w = 36 \][/tex]

[tex]\[ w = \frac{36}{4} \][/tex]

[tex]\[ w = 9 \][/tex]

 Now, we can find the length [tex]\( l \):[/tex]

[tex]\[ l = 2w \][/tex]

[tex]\[ l = 2 \times 9 \][/tex]

[tex]\[ l = 18 \][/tex]

However, since we initially assumed[tex]\( l = 2w \)[/tex] to find the width, we need to adjust the length to account for the actual fencing used. We have two widths and one length, so the correct equation is:

[tex]\[ l + 2w = 36 \][/tex]

[tex]\[ 18 + 2 \times 9 = 36 \][/tex]

[tex]\[ 18 + 18 = 36 \][/tex]

[tex]\[ 36 = 36 \][/tex]

Therefore, the dimensions of the pen are 9 meters by 6 meters, with the wall forming the side of 18 meters.

 The final answer is that the pen should be built with dimensions of 9 meters by 6 meters, with the wall forming one of the 9-meter sides.

Pq Slope * Vt Slope should equal -1

4 * -1/4 = -1 Yes they are perpendicular.

The slope for the first equation is 4, and after transforming the second equation into slope-intercept form the slope is -0.25. Since these slopes are negative reciprocals of each other, the lines pq and vt are perpendicular.

The given equations are y=4x+3 (equation of line pq), and 2x+8y=6 (equation of line vt). To find out if these lines are perpendicular, we need to rewrite the second equation in slope-intercept form (y=mx+b). You can achieve this by isolating y.

Here are the steps:

At this point, you can see that the slope of this line is -0.25.

Line pq has a slope of 4, and line vt has a slope of -0.25. Two lines are perpendicular if their slopes are negative reciprocals of each other. The negative reciprocal of 4 is -0.25, so we can conclude that lines pq and vt are perpendicular.

Final answer:

When considering that yards vary directly as feet and 2 feet represent 30 yards, we determine that 3 feet represent 45 yards by setting up a direct variation proportion.

Explanation:

In the problem where yards vary directly as feet, we are given that 2 feet represent 30 yards. To find out how many yards represent 3 feet, we need to set up a proportion based on the given information that 1 yard equals 3 feet. Using the direct variation, we can create the equation: 2 feet / 30 yards = 3 feet / x yards, where x represents the unknown number of yards.

If we simplify the first ratio, 2 feet is to 30 yards as 1 foot is to 15 yards, since dividing both sides by 2 gives us: 1 foot / 15 yards. Therefore, we can continue the proportion as: 1 foot / 15 yards = 3 feet / x yards.

Now, let's solve for x by multiplying both sides of the equation by the denominator on the right side (x yards) to eliminate the fraction: 1 foot / 15 yards = 3/x, which simplifies to x = 3 * 15. After performing the multiplication, we get x = 45 yards. Therefore, 3 feet represent 45 yards on the drawing scale.
