[-b + √(b² -4ac)]/2a

a = 2, b = 8, c = 5

Substituting the values into the expression

[-b + √(b² -4ac)]/2a

= [-8 + √((8)² - 4(2)(5))]/2(2)

= [-8 + √(64 - 40)]/4

= [-8 + √(24)]/4

= [-8 + 2√6]/4

= -2 + 1/2(√6)

= -0.775

≈ -0.8

28.

S = 2πrh + 2πr²

r = 2.3, h = 7.1 (Take π = 3.14)

Thus,

S = 2(3.14)(2.3)(7.2) + 2(3.14)(2.3)²

S = 103.9968 + 33.2212

S = 137.218

S ≈ 137.22

29.

V = 4/3 πr³

r = 2.3(Take π = 3.14)

V = 4/3 × 3.14 × (2.3)³

V = 50.939

V ≈ 50.94

Hence, the value of V is 50.94

The average rate of change of f(x) from x = -3 to x = 6 is 7.

What is meant by average?

The term "average" is used to describe a number that represents the central or typical value in a set of data. There are several different types of averages, including the mean, median, and mode.

To find the average rate of change of a function, we need to compute the difference between the function values at the two given points, and then divide by the difference in the input values.

For the function [tex]f(x) = x^2 + 4x - 15[/tex], the value of the function at [tex]x = -3[/tex] is:

[tex]f(-3) = (-3)^2 + 4(-3) -15 = 9 - 12 - 15 = -18[/tex]

The value of the function at [tex]x = 6[/tex] is:

[tex]f(6) = 6^2 + 4(6) - 15 = 36 + 24 - 15 = 45[/tex]

The difference in the function values is:

[tex]f(6) - f(-3) = 45 - (-18) = 63[/tex]

The difference in the input values is:

6 - (-3) = 9

Therefore, the average rate of change of f(x) from x = -3 to x = 6 is:

average rate of change = [tex](f(6) - f(-3)) / (6 - (-3)) = 63 / 9 = 7[/tex]

So, the average rate of change of f(x) from x = -3 to x = 6 is 7.

Your longitude in DMS is 135 degree. So the option D is correct.

This is because there are 12 hours left in the local time ( i.e. 12 hours noontime or mid-day).

As UT (or GMT) time is 9 p.m., there are 9 hours between GMT time and local time.

9 hours = 9 × 60 minutes = 540 minutes

Now, we know that:

Every four minutes, the Earth turns one degree.

Thus, 1-degree longitude difference = 4 minutes

Or, 4 minutes of time difference = 1 degree of longitude

Or, 1 minute of time difference = 1/4 degree of longitude

Or, 540 minutes of time difference = (1/4) × 540 degrees of longitude

540 minutes of time difference = 135 degrees of longitude

Also, we can infer that the current location is in the Western hemisphere because we know that it is 9 hours behind GMT (or UT) time.

Hence, the longitude of the current location = 135⁰

The car was travelling with the speed of 183.5 mph when the brakes were applied.

The pace at which an object travels a certain distance can be described using the speed formula. The distance that a body travels in a certain amount of time is a common way to measure speed. M/s is the SI unit of speed. We will learn more about the speed formula and its uses in this section.

Let's continue and investigate the speed formula in this part in more detail. Speed can be expressed in a variety of ways, including m/s, km/hr, miles/hr, etc. [LT-1] is the dimensional formula for speed. A body's speed may be defined as how quickly it is going. The equation for a given body's speed may be written as,

Speed = Distance ÷ Time

We have the equation,

[tex]s=\frac{\sqrt{d} }{0.04}[/tex]

we have the value of d as 54

putting the value pf d in the equation we get,

Step-by-step explanation:

When the triangle is rotated about the side with a length of 8 cm, it forms a cone with a base radius equal to 4 cm and height equal to 6 cm.

Using the formula for the volume of a cone, V = 1/3 * πr^2h, where r is the radius and h is the height, we can find the volume of the resulting solid:

V = 1/3 * π * 4^2 * 6

V ≈ 100.53 cubic centimeters

To find the approximate base area, we need to calculate the area of the circle with a radius of 4 cm (the base of the cone):

A = πr^2

A ≈ 50.27 sq. cm

Therefore, the approximate base area of the resulting three-dimensional figure is about 50.27 sq. cm.

So, the closest option available in the given choices is 38 sq. cm, but the correct answer based on calculations is approximately 50.27 sq. cm.

Step-by-step explanation:

The probability that the second crayon drawn is blue and the first crayon drawn is blue is 1/28.

To solve this problem, we can use the conditional probability formula:

P(A and B) = P(B|A) * P(A)

where:

P(A and B) is the probability that both events A and B occur

P(B|A) is the probability of event B given that event A has already occurred

P(A) is the probability of event A occurring

In this case, we want to find the probability of selecting a blue crayon on the second draw given that the first crayon selected was blue. So we have:

P(the second crayon is blue and the first crayon is blue) = P(blue on the second draw | blue on the first draw) * P(blue on the first draw)

To find each of these probabilities, we can start by calculating the total number of possible outcomes:

Total number of outcomes = 8 crayons in the box

Next, we need to find the probability of selecting a blue crayon on the first draw:

P(blue on the first draw) = 2/8 = 1/4

After the first blue crayon has been set aside, there are only 7 crayons left in the box, so the probability of selecting a blue crayon on the second draw given that the first crayon was blue is:

P(blue on the second draw | blue on the first draw) = 1/7

Putting it all together:

P(the second crayon is blue and the first crayon is blue) = P(blue on the second draw | blue on the first draw) * P(blue on the first draw)

= (1/7) * (1/4)

= 1/28

Therefore, the probability that the second crayon drawn is blue and the first crayon drawn is blue is 1/28.

The function f(x) = x² - 7 is an example of a function that is neither even nor odd, as it does not exhibit either type of symmetry.

To determine whether a function is even, odd, or neither, we need to examine its algebraic form and look for a particular type of symmetry.

Let's apply this concept to the given function, f(x) = x² - 7. To determine whether f(x) is even or odd, we need to evaluate f(-x) and compare it to f(x).

f(-x) = (-x)² - 7 // substitute -x for x

= x² - 7 // simplify

Comparing f(-x) to f(x), we can see that they are not equal:

f(-x) = x² - 7

f(x) = x² - 7

Since f(-x) is not equal to f(x), the function is not even. To determine whether it is odd, we need to evaluate f(-x) + f(x) and see if the result is zero.

f(-x) + f(x) = (x² - 7) + (x² - 7) // substitute -x for x in the second term

= 2x² - 14

Since f(-x) + f(x) is not equal to zero for all values of x, the function is not odd either.

Therefore, we can conclude that the given function, f(x) = x² - 7, is neither even nor odd.

In a right triangle, one of the angles measures 90 degrees, and the other two angles are acute angles that add up to 90 degrees. Let's call the measures of the two acute angles x and y.

We know that x and y differ by 22 degrees. So we can set up an equation:

x - y = 22

We also know that x + y = 90, since the two acute angles add up to 90 degrees.

Now we can solve this system of equations for x and y. One way to do this is to add the two equations together, which eliminates y:

x - y + x + y = 22 + 90

2x = 112

x = 56

Now we can substitute x = 56 into one of the equations to find y:

x + y = 90

56 + y = 90

y = 34

Therefore, the measures of the two acute angles of the right triangle are 56 degrees and 34 degrees.

If Atharv has 10 nickels and dimes in his pocket, and they have a combined value of 70 cents, then he has 1 nickels and 4 dimes.

Let x be the number of nickels and y be the number of dimes. A nickel is worth 5 cents, and a dime is worth 10 cents. Therefore, we can write two equations:

x + y = 10 (since he has 10 coins in total)

5x + 10y = 70 (since the combined value of the coins is 70 cents)

We can simplify the second equation by dividing both sides by 5:

x + 2y = 14

Now we can use the first equation to solve for one of the variables in terms of the other. Let's solve for x:

x + y = 10x = 10 - y

Now we can substitute this expression for x into the second equation:

x + 2y = 14(10 - y) + 2y = 14
