Write a story about elevation that this expression could represent: 56 + (-56)
The correct statement that represents the expression is:
An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0mGiven the expression 56 + (-56).
We can see that this is an inverse rule where a value and its negative are added together.Let us assume the values are distance covered by an object.
The correct statement that represents the expression is:
An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0mThis show that 56 + (-56) = 56 - 56 = 0

In a school, 35% of the students are girls and the number of boys are 910, find the number of girls in the school. Also, find the total enrolment in the school
Answer:
Step-by-step explanation:
Percentage of girls = 35%
Percentage of boys = 100 - 35 = 65%
There are 910 boys:
65% = 910
Find the number of students in the school:
1% = 910 ÷ 65 = 14
100% = 14 x 100 = 1400
Answer: There are 1400 students in the school

An isosceles triangle has a vertex angle of 70°. What is the measure of each base angle?
70°
55°
20°
Answer: 55 degrees (choice B)
============================================================
Explanation:
Let x be the measure of each congruent base angle.
The three interior angles of any triangle always add to 180 degrees.
x+x+70 = 180
2x+70 = 180
2x = 180-70
2x = 110
x = 110/2
x = 55 degrees
Answer:
55 degrees
Step-by-step explanation:
Since the triangle is isosceles there are two congruent base angles and 1 vertex angle. The three angles add up to 180 degrees.
180 minus the vertex angle of 70 degrees leaves 110 degrees for the remaining two angles. Divide 110 by 2 to get the measure of each base angle.
180 - 70 = 110/2 = 55 degrees

Integrala x la a treia ori ln la a doua dx va rog
I don't speak Romanian, but the closest translation for this suggests you're trying to compute
\(\displaystyle \int x^3 \ln(x)^2 \, dx\)
Integrate by parts:
\(\displaystyle \int x^3 \ln(x)^2 \, dx = uv - \int v \, du\)
where
u = ln(x)² ⇒ du = 2 ln(x)/x dx
dv = x³ dx ⇒ v = 1/4 x⁴
\(\implies \displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac12 \int x^3 \ln(x) \, dx\)
Integrate by parts again:
\(\displaystyle \int x^3 \ln(x) \, dx = u'v' - \int v' du'\)
where
u' = ln(x) ⇒ du' = dx/x
dv' = x³ dx ⇒ v' = 1/4 x⁴
\(\implies \displaystyle \int x^3 \ln(x) \, dx = \frac14 x^4 \ln(x) - \frac14 \int x^3 \, dx\)
So, we have
\(\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac12 \left(\frac14 x^4 \ln(x) - \frac14 \int x^3 \, dx \right)\)
\(\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac18 x^4 \ln(x) + \frac18 \int x^3 \, dx\)
\(\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac18 x^4 \ln(x) + \frac18 \left(\frac14 x^4\right) + C\)
\(\displaystyle \int x^3 \ln(x)^2 \, dx = \frac14 x^4 \ln(x)^2 - \frac18 x^4 \ln(x) + \frac1{32} x^4 + C\)
\(\boxed{\displaystyle \int x^3 \ln(x)^2 \, dx = \frac1{32} x^4 \left(8\ln(x)^2 - 4\ln(x) + 1\right) + C}\)

Please can someone who knows the right answer help me? From a group of 5 boys and 3 girls, a boy and a girl will be selected to attend a conference. In how many ways can the select be made?
The selection can be made in 15 different ways, taking into account the distinct combinations of a boy and a girl from the given group of 5 boys and 3 girls.
To determine the number of ways a boy and a girl can be selected from a group of 5 boys and 3 girls to attend a conference, we can use the concept of combinations.
The number of ways to choose one boy from 5 boys is 5C1, which is equal to 5. Similarly, the number of ways to choose one girl from 3 girls is 3C1, which is equal to 3.
To select one boy and one girl, we need to multiply the number of ways to choose a boy and a girl together. Using the multiplication principle, we multiply the number of choices for each category: 5C1 * 3C1 = 5 * 3 = 15.
Therefore, there are 15 ways to select a boy and a girl from the given group to attend the conference.
Each combination represents a unique pair consisting of one boy and one girl. For example, if the boys are labeled as B1, B2, B3, B4, and B5, and the girls are labeled as G1, G2, and G3, the possible pairs could be (B1, G1), (B1, G2), (B1, G3), (B2, G1), (B2, G2), and so on, up to (B5, G3).

Step-by-step explanation:
Answer:
d. 5. 1 ≤ d ≤ 2
e. 4. t ≥ 5
f. 1. -z < 4
Step-by-step explanation:
d. d is between 2 and 1
The statement "d is between 2 and 1" means that d is greater than 1 and less than 2. We can represent this using the inequality 1 < d < 2. However, the answer choices do not match this exact form of inequality. To rephrase the inequality in a way that matches the answer choices, we can use the logical "and" operator to combine two inequalities: d is greater than or equal to 1, and d is less than or equal to 2. This gives us the inequality 1 ≤ d ≤ 2, which is answer choice 5.
e. t is not less than 5
The statement "t is not less than 5" means that t is greater than or equal to 5. This can be represented using the inequality t ≥ 5, which is answer choice 4.
f. The negative of z is not greater than 4
The statement "the negative of z is not greater than 4" means that -z is less than or equal to 4. We can represent this using the inequality -z ≤ 4, which is answer choice 2. However, the question does not include an answer choice for -z < 4, which is also true based on the statement.

Step-by-step explanation:
Labeling the rooms A, B, and C makes it easier.
Room A - All BUT 4
Room B - All BUT 4
Room C - All BUT 4
Since you can see each room is all but four, you can split the 4 into 2 into 2 OTHER rooms than the one stated. For example, Room A is all but 4, so 2 go to Room B and the other 2 go to Room C because each room is all BUT 4.
Basically, 2+2+2 = 6
What is the image point of (0, -6) after the transformation D1/2 ° r y=-x?
The image point of (0, -6) after the transformation D1/2 ° r y = -x is (-3, 0).
To find the image point of (0, -6) after the transformation D1/2 ° r y=-x, we need to apply the transformation steps in the given order.
First, let's consider the reflection y = -x. This reflection involves swapping the x and y coordinates. So, the image point after the reflection will be (-6, 0).
Next, we need to apply the dilation by a scale factor of 1/2 (D1/2). This dilation involves multiplying the x and y coordinates by the scale factor. Therefore, the image point after the dilation will be (-6/2, 0/2), which simplifies to (-3, 0).
The transformation involves reflecting the point across the line y = -x and then dilating it by a scale factor of 1/2.

What are the domain and the range of function w?
For the given function we have:
domain: x ≥ 0range: w(x) ≥ -4.How to get the domain and range of the function?Here we have the function:
\(w(x) = -(3x)^{1/2} - 4\)
First, how do we get the domain?
Notice that we can only evaluate the square root in arguments equal or larger to zero (if we want a real outcome) then we need to have:
x ≥ 0.
Now, to get the range, maximum value is the one that we get when we evaluate in the minimum of the domain:
\(w(x) = -(3*0)^{1/2} - 4 = -4\)
And as x increases, the value of w(x) decreases, then the range is:
R: w(x) ≥ -4.

The side of a triangle are in the ratio 4:4:3 what kind of triangle is it (b) calculate the smallest angle of the triangle to the nearest degree
The smallest angle of the equilateral triangle is 60 degrees
If the sides of a triangle are in the ratio 4:4:3, it implies that the lengths of the sides are proportional.
To determine the type of triangle, we examine the side lengths. Since all three sides are equal in length, we have an equilateral triangle.
For an equilateral triangle, all angles are equal. To calculate the smallest angle, we divide the total sum of angles in a triangle (180 degrees) by the number of angles, which is 3:
Smallest angle \(= \frac{180}{3} = 60\)\) degrees.
Therefore, the smallest angle of the equilateral triangle is 60 degrees (to the nearest degree).
