Answer:

to convert a fraction to a decimal, divide the numerator by the denominator.

Hope this helps.

Answer:

S' (1,-2)

S'' (0,0)

Step-by-step explanation:

The coordinates of the image after a reflection across y=-1 followed by a translation <2,-1> is S' (1,-2) and S'' (0,0).

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that,

S(1,0)

If it is reflected across y=-1 followed by a translation <2,-1>.

The coordinates of the image will be S' (1,-2) and S'' (0,0).

Thus,the coordinates of the image after a reflection across y=-1 followed by a translation <2,-1> is S' (1,-2) and S'' (0,0).

U do 11.4/2 then u add that number to 11.4 and get your answer

Answer:

Step-by-step explanation:

Given that :

Summit of Mount Washington = 6288 ft

Location of Carter notch = elevation of 3288 ft

The change in elevation will be :

A reduction in elevation from the summit of Mount Washington to Carter Notch

(6288ft - 3288ft) = 3000ft

Since it is a reduction from the initial elevation point or height, Then the change in elevation will be negative ;

= - 3000ft

We want to find the change in elevation of Sylvie and Bono. The point that represents the change in elevation is the point -3000.

To get the change in elevation we just need to compute:

Final elevation - Initial elevation

We know that the initial elevation is:

initial elevation = 6,288 ft

The final elevation is at an elevation of 3,288 ft, then we have:

final elevation = 3,288 ft

So the change in elevation is just:

3,288 ft - 6,288 ft = -3,000 ft

So the point that represents the change in elevation in feet is the point -3000.

Answer:

The answer would be A/B=H

Step-by-step explanation:

To get rid of the B that is connected to the H, you would do the opposite of what they used. Meaning since the two were multiplied you would divide them. So, you would take your b and divide it on both sides of the equal sign. B and B cancels each other out so you are left with A/B which equals H.

Answer:

Step-by-step explanation:

because putting values

x=1 in y=4x+9

we get y=4+9=13

The area of the region under the parabola y = 5x - x^2, where 1 ≤ x ≤ 4, is 14.33 square units.

To find the area under the parabola, we need to integrate the equation y = 5x - x^2 with respect to x over the given interval [1, 4]. The integral represents the area between the curve and the x-axis.

Integrating y = 5x - x^2 gives us the antiderivative F(x) = (5/2)x^2 - (1/3)x^3 + C, where C is the constant of integration. To find the definite integral over the interval [1, 4], we evaluate F(4) - F(1).

F(4) = (5/2)(4)^2 - (1/3)(4)^3 + C = 40 - (64/3) + C

F(1) = (5/2)(1)^2 - (1/3)(1)^3 + C = 5 - (1/3) + C

Substituting these values into the definite integral expression, we have:

Area = F(4) - F(1) = (40 - (64/3) + C) - (5 - (1/3) + C)

= 14.33

The area of the region under the parabola y = 5x - x^2, where 1 ≤ x ≤ 4, is approximately 14.33 square units.

Answer:

x > -100/9

Step-by-step explanation:

1. -45x +310 <810

2. look for like terms and isolate them .

3. -45x+310-310< -810 -310

4.; -45x < 500

5. x > -100/9

NB: The inequality sign changes when dividing by negative number or term.

The correct answer is: c) 1/3, 5/3 The cosine function has a period of 2π, meaning it repeats every 2π radians.

To find the solutions for x in the equation 12cos(2x) + 10 = 16, we can solve it algebraically. Let's begin:

12cos(2x) + 10 = 16

Subtract 10 from both sides:

12cos(2x) = 6

Divide both sides by 12:

cos(2x) = 1/2

Now, we want to find the two smallest positive solutions for cos(2x) = 1/2. The cosine function has a period of 2π, meaning it repeats every 2π radians. We are looking for solutions in the range of 0 to 2π.

The cosine function has values of 1/2 at two specific angles: π/3 and 5π/3.

So, we can set up the following equations:

2x = π/3 and 2x = 5π/3

Solving for x in each equation:

For 2x = π/3:

x = π/6

For 2x = 5π/3:

x = 5π/6

Thus, the two smallest positive solutions for x in the equation 12cos(2x) + 10 = 16 are x = π/6 and x = 5π/6.

Therefore, the correct answer is:

c) 1/3, 5/3

To find the volume of the right regular triangular pyramid, where x = 30 cm and h = 27 cm, the exact answer is 900π cm³, and the approximation to the nearest hundredth is 3507.39 cm³.

The volume of a pyramid can be calculated using the formula:
Volume = (1/3) * Base Area * height
In the case of a right regular triangular pyramid, the base is a regular triangle, so the base area can be found using the formula for the area of an equilateral triangle:
Base Area = (sqrt(3)/4) * x²
Given that x = 30 cm, we can calculate the base area as:
Base Area = (sqrt(3)/4) * 30²
Base Area = (sqrt(3)/4) * 900
Base Area = (900/4) * sqrt(3)
Base Area = 225 * sqrt(3)
The volume can now be calculated by substituting the values of the base area and height into the volume formula:
Volume = (1/3) * (225 * sqrt(3)) * 27
Volume = 675 * sqrt(3) * 27
Volume = 18225 * sqrt(3) cm³
Approximating to the nearest hundredth, we find that the volume is approximately 3507.39 cm³.

The expected value for X is 1.56.

Expected value is the mean value that we would expect if we conducted the same experiment many times and recorded the result of each trial. This formula is used to calculate the expected value for X.

This formula is used to calculate the expected value for X:E(X) = Σ [ xi * P(xi) ] where xi represents the value of X, and P(xi) is the probability of X taking the value xi.

The value of xi is multiplied by its corresponding probability and then summed over all the values of X.

This gives the expected value of X. Now, let us use the formula to calculate the expected value of X:

E(X) = (0 * 0.10) + (1 * 0.05) + (2 * 0.02) + (1 * 0.12) + (0 * 0.10) + (2 * 0.10) + (3 * 0.16) + (0 * 0.06) + (1 * 0.11) + (2 * 0.28)E(X) = 0 + 0.05 + 0.04 + 0.12 + 0 + 0.20 + 0.48 + 0 + 0.11 + 0.56E(X) = 1.56

Answer:

[tex]7:4:2[/tex]

Step-by-step explanation:

Assign variables for the 3 numbers. Let the first number be x, the second number be y, and the third number be z.

"The sum of the 3 numbers is 145", therefore:

"Seven times the second number is twice the first number":

"Twice the second number is six times the third number":

We can solve for x, y and z using this system of equations. Let's solve for y in the first equation by putting the other variables in terms of y in Equations II and III.

Solve for x in [tex]\text{Equation II}[/tex]:

Solve for z in [tex]\text{Equation III}[/tex]:

Substitute these values into [tex]\text{Equation I}[/tex] to solve for y.

Combine like terms using common denominators. The least common denominator is 6. Multiply [tex]\frac{7}{2} y[/tex] by [tex]\frac{3}{3}[/tex], multiply [tex]y[/tex] by [tex]\frac{6}{6}[/tex], and multiply [tex]\frac{1}{3} y[/tex] by [tex]\frac{2}{2}[/tex] to make all of the denominators = 6.

Add the fractions together.

Solve for y by multiplying both sides by [tex]\frac{6}{29}[/tex].

We have found that y = 30. Now we can use this known value in order to solve for both x and z in Equations II and III.

[tex]\text{Equation II}:[/tex]

[tex]\text{Equation III}:[/tex]

We have found that x = 105, y = 30, and z = 10. Now we can write the new ratio of these 3 numbers:

"Write the new ratio of the three numbers if the second number doubles and the third number is increased by one less than one fifth of the first number":

The question asks for the new ratio once we evaluate these expressions. The variable x is the only one that stays the same at the end: 105.

Our final numbers are x = 105, y = 60, and z = 30. We can create the ratio between these numbers by fully simplifying them. Right now we have [tex]x:y:z=105:60:30[/tex]. Start by dividing all of the numbers by 5.

We get [tex]21:12:6[/tex]. This ratio can be simplified further by dividing all of the numbers by 3. We then get the ratio of: [tex]7:4:2[/tex].

This ratio cannot be simplified any further, therefore, it is the new ratio of the three numbers.

d) Rolling an even number that is less than 2 is not a valid outcome when rolling a die.therefore, option d) is correct.

The outcome that is not possible is (d) rolling an even number that is less than 2 on a die.

A standard die has six sides numbered from 1 to 6, and all the even numbers on a standard die are 2, 4, and 6.

The statement "rolling an even number that is less than 2" contradicts the fact that the lowest even number on a die is 2.

Thus, it is not possible to roll an even number that is less than 2 on a standard die, making it an invalid outcome.
