Write a directed number suggested by the following :
A 14 degrees below zero

B altitude 200 metres

Answer:  [tex]\text{y} \ge 2[/tex]

Reason:

The lowest point on the graph occurs when y = 2. This is a closed endpoint so it's included with the graph. So either y = 2 or y > 2, both of which combine to get the answer shown above.

The values of k for which the line y = 2x + k + 2 cuts the curve y = 2x² + (k + 2) + 8 at two distinct points are; k > -12 or k < 4

We are given the equation of the line as;

y = 2x + k + 2

Equation of the curve is;

y = 2x² + (k + 2) + 8

Now, to find the the values of k for which the line y = 2x + k + 2 cuts the curve y = 2x² + (k + 2) + 8 at two distinct points, we will just equate both equations to get;

2x + k + 2 =  2x² + (k + 2) + 8

2x + k + 2 =  2x² + kx + 2x + 8

2x² + kx + (-k + 6) = 0

Now, Two distinct solutions is the same as having a positive discriminant.

b² - 4ac > 0

k² - 4(2 * (-k + 6)) > 0

k²  + 8k - 48 > 0

Solving using quadratic equation calculator gives;

k > -12 or k < 4

The equation that can be used to get the number of men if the total number of people who attended was 2400 is x + 3x + x + 240 = 2400.

It should be noted that from the information given, in the health camp the number of children was three times the number of men and the number of men was 240 less than the number of women.

Number of men = x

Number of children = 3x

Number of women = x + 240

Total number of people = 2400

The appropriate equation will be:

x + 3x + x + 240 = 2400

5x + 240 = 2400

Collect like terms

5x = 2400 - 240

5x = 2160

Divide

x = 2160 / 5

x =432

Therefore, the total number of men is 432 men.

7-(-4) is 4 units from 7 in the negative direction. See the explanation and the linear scale attached.

The direction being referred to is the direction of the number on a numerical scale or Linear Scale.

In the attached linear scale, we can see that the arrow stops at 11. This is arrived at by expanding the bracket:

7 - (-4)

the subtraction signs cancel out each other creating a positive sign. Hence we have:

7 + 4

= 11.

Hence, 11 is 4 units away from 7 in the negative direction. That is going toward zero is negative or a reduction hence, to get to 7 you need to go toward the negative section of the scale.

2 teaspoon of cinnamon need if he uses 3 cups of yogurt

By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other. There are two different categories for ratios. The first is a part to part ratio, whereas the second is a part to whole ratio. The relationship between two separate entities or organizations is shown by the part-to-part ratio. For instance, a class has a 12:15 boy-to-girl ratio, whereas the part-to-whole ratio describes how one group compares to another. For instance, five people enjoy reading books out of every ten persons. Since the ratio of the component to the total is 5:10, 5 out of every 10 persons enjoy reading.

Using the expected value of a discrete distribution, the correct option is given as follows:

E(penny) = 1.75 and E(nickel) = 1.5, so she should play with the pennies.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

When 3 coins are tossed, the probabilities are given as follows:

Hence the distribution for the penny points is:

The expected value for the penny points is:

-2 x 0.25 + 3 x 0.75 = 1.75.

When 2 coins are tossed, the probabilities are given as follows:

Hence the distribution for the nickel points is:

The expected value of nickel points is:

E(X) = -2 x 0.5 + 5 x 0.5 = 1.5.

Due to the higher expected value, she should play with the pennies and the third option is correct.

The quadratic function in the standard form containing the point (-7, 5) and vertex (1, 9) is y = (-1/16)(x - 1)² + 9.

The vertex form of a quadratic function with vertex (h, k) is written as

y = a(x - h)² + k, where (x, y) denotes a point on the parabola. Real integers a, h, and k are also included.

Given:

Point (x, y) = (-7, 5)  

Vertex (h,k) = (1, 9)

The general equation of quadratic function in vertex form is:

 y = a(x - h)² + k

To solve for a, substitute the given point (x,y) = (-7,5) into the equation.

5 = a(-7 - 1)² + 9

a(-8)² = -4

a = -4 /64

a = -1/16

Therefore, the required quadratic function is,

 y = (-1/16)(x - 1)² + 9

Step-by-step explanation:

For the function x³ - 6x² + 11x - 6, we have that:

a) The x-intercepts are: x = 1, x = 2, x = 3.

b) The y-intercept is of y = -6, while the end behavior is that it decreases to the left and increases to the right.

The function is given as follows:

f(x) =  x³ - 6x² + 11x - 6

x - 3 is a factor of the function, meaning that x = 3 is a x-intercept and the function can be written as follows:

x³ - 6x² + 11x - 6 = (x - 3)(ax² + bx + c)

Then we have to build a system of equations to find the coefficients as follows:

x³ - 6x² + 11x - 6 = ax³ + (b - 3a)x² + (c - 3b)x - 3c.

Then the coefficients are given as follows:

Then the factor is given by:

x² - 3x + 2.

Hence the other intercepts of the polynomial are found when:

x² - 3x + 2 = 0

(x - 2)(x - 1) = 0.

x - 2 = 0 -> x = 2.

x - 1 = 0 -> x = 1.

The y-intercept is the value of f(x) when x = 0, that is, f(0), hence:

f(0) = 0³ - 6(0)² + 11(0) - 6 = -6.

For the end behavior, we need to find the limits as x goes to infinity, hence:

When the limit goes to infinity, we consider only the term with the highest exponent of the polynomial.

The fraction of hour that remained is 1/2 hour.

It is given in the question that three students were scheduled to give book reports in 1 hour.

After the first report, 2/3 hour remained. The next report took 1/6 hour.

We have to find the fraction of hour that remained.

We know that,

Total time for reports = time taken for first report + time taken for second report + time remained for third report

Hence, we can write,

Time taken for first report =  1-2/3 = 1/3 hour

Time taken for second report = 1/6 hour

1 = 1/3 + 1/6 + time remained for third report

1 = 2/6 + 1/6 + time remained for third report

1 = 3/6 + time remained for third report

1-3/6 = time remained for third report

Answer:

Step-by-step explanation:

I may have made a mistake somewhere along the way but if not then it is 51 gallons.

The way i did this was to multiply 20 minutes by 3 to equal an hour, then multiply that by 24 to equal a day, then multiply that by 365 to equal a year.

That gives you the numbers you need to multiply the ounce by. So first multiply 1/4 by 3 to get 3/4. Next you multiply 3/4 by 24 to get 72/4 or 18. Then you multiply 18 by 365 to get 6570 ounces in a year. Finally you translate that to gallons and you get 51.328125, which rounds down to 51.

Here, ‘a’ is the vertical side i.e. wall

‘b’ is the base side i.e. bottom = 5 m

‘c’ is the hypotenuse i.e. the ladder = 10 m

If b = 5 m, c = 10 m

Then, a2 = c2 - b2 = (10 x 10) - (5 x 5) = 75

a = √75 = 8.66 m

The the top of the ladder is at 8.66 m.
