Answer:
2.478 million at the end of 2015
Step-by-step explanation:
Multiply the amount of population at the end of 2012 times 6%
2.1 times 0.06 = 0.126 million
So, at a constant rate, yearly, the population of Dubai increases 0.126 million
2015-2012 = 3
0.126 times 3 = 0.378 million
2.1 + 0.378 = 2.478 million

What Has a central point that stays fixed and everything else moves around that point in a circle- full rotation is 360 degrees.
Answer:
Rotary motion.
Step-by-step explanation:
Motion describes the movement of objects with respect to time.
When an object performs a circular or rotary motion, every point on the object moves around a central point in a continuous manner. Examples of objects that performs circular motion are: blades of an electric fan, rotation of the earth about its axis, the wheel of a moving bicycle etc.
From the cited examples, it would be observed that all points on the objects moves around a fixed central point.

Lucia is making blackberry jam. She starts with 25 cartons of blackberries. After making 9 jars of jam, she has 10 cartons of blackberries left. Lucia's jars all have the same capacity. Select true or false for each statement.
Answer:
A = true
B = false
C = false
D = True
Step-by-step explanation:
Cartons of blackberries = 25
Jars of blackberry jam made = 9
Cartons of blackberries left = 10
Cartons of blackberry used = Cartons of blackberries - Cartons of blackberries left
= 25 - 10
= 15
Cartons of blackberry used = 15
Cartons of blackberry used per jam = Cartons of blackberry used / Jars of blackberry jam made
= 15/9
= 5/3
A = true
15 jars of blackberry = Cartons of blackberry used per jam × jars of black berry made
= 5/3 × 15
= 75/3
= 25 cartons of blackberry
B = false
She can make 15 jars of blackberry jam using 25 cartons of blackberry
C = false
Cartons of blackberries left = 10
Number of blackberry jam made with 10 cartons of blackberry = Cartons of blackberries left / Cartons of blackberry used per jam
= 10 ÷ 5/3
= 10 × 3/5
= 30/5
= 6
D = True

(48) b. definition of complementary
(49) a, m<2 = m<3
(50) d. definition of congruent angles
Step-by-step explanation:
From the given question, the proof can be completed as;
Statement Reason
1. <2 and < 1 are complementary (47) c. given
<3 and <1 are complementary
2. m<2 + m<1 = [tex]90^{o}[/tex] (48) b. definition of complementary angles
m<3 + m<1 = [tex]90^{o}[/tex]
3. m<2 + m<1 = m<3 + m<1 3. Substitution property
4. (49) a, m<2 = m<3 4. Subtraction property
5. <2 ≅ <3 (50) d. definition of congruent angles
Therefore,
(47) c. given

(50) d. definition of congruent angles
Someone help- I don't know how to solve this- maybe my teacher typed it in wrong? 2.4(m - 3) = 3.8 = -8.2
Answer:
m = 4.58
Step-by-step explanation:
Given equation :
2.4 ( m - 3) = 3.8
So now we open the brackets and multiply the terms.
⇒ 2.4 m - 7.2 = 3.8
⇒ 2.4 m = 3.8 + 7.2
⇒ 2.4 m = 11
⇒ m = [tex]\frac{11}{2.4}[/tex]
⇒ m = 4.58
Therefore, the correct value of the variable m by solving the equation is 4.58
What's the area of it
Answer:
33.5 units²
Step-by-step explanation:
We can see this figure as 2 shapes: a square and a triangle. The square measures 4 x 4, and it's area is 16. That leaves the triangle, which has half the area of a quadrilateral that measures 5 x 7. The area of the quadrilateral is 35, and the triangle has an area of 17.5, which is half of that. Adding them together, we get 33.5.
Answer:
33.5 unit²
it's a mixture of triangle and square.
draw a imaginary straight line across the figure from that line which has length of 3 units and now you can see the triangle and the square. Use the formula to find area of triangle and area of square and the sum of their area will be the area of this whole figure i.e 35.5 unit²
Remmi wrote the equation of the line y = one-third (x + 2) He solved for x and got x = 3 y minus 2 Which of the following is an equivalent equation for x?
Answer:
x = 3y - 2
Step-by-step explanation:
Given the equation y = 1/3(x+2), we are to make x the subject of the formula;
y = 1/3(x+2)
Cross multiply
3y = x+2
Subtract 2 from both sides
3y - 2 = x+ 2 -2
3y - 2 = x
Swap
x = 3y - 2
This give the required equation

what is f(x) = 3 × 8^x when x is equal to 3
Answer:
Answer is 1536
Step-by-step explanation:
plug in 3 for x
f(3) = 3*8^3 = 1536
Answer:
1536
Step-by-step explanation:
f(x) = 3 * 8 ^ x
x = 3
f(3) = 3 * 8 ^ 3
8^3 = 8 * 8 * 8
8^3 = 512
f(3) = 3 * 512
f(3) = 1536

Step-by-step explanation:
Hey there!
Given function is f(X) = 11x+7.
Let f(X) be y.
So, y = 11x+7
Interchanging"X" and "y" we get;
X = 11y+7
or, X-7 = 11y
or, y = (x-7)/11
Therefore {f}^{ - 1} (x) = \frac{x - 7}{11} [/tex]

What is the relationship between the angles that are formed by two intersecting lines?
Hi there!
Adjacent angles, or angles that are next to each other, add up to 180 degrees. They are supplementary.
Examples: 1 and 4, 3 and 4, 2 and 3, 1 and 1
Opposite angles, or angles that are opposite of each other, have the same measure.
Examples: 1 and 3, 2 and 4
I hope this helps!
10 points:) please help i keep getting the wrong answer
Answer:
Step-by-step explanation:
There are three surfaces to add up to.
A1, the top surface of the cone (r=1,h=2)
A2, The curved surface of the cylinder (r=1 , h = 13-2 = 11)
A3, The circular base of the cylinder (r=1)
The slant height of the cone, s = sqrt(1^2+2^2), s = sqrt(5)
The length (circumference of the base), l = 2 pi r = 2pi r = 2pi
The area is
A1 pi s l = pi * sqrt(5) (2 pi r) = 2(pi^2)sqrt(5)
The curved surface has an area of
A2 = 2 pi r h = 2pi (1)(11) =22pi
The base has an area of
A3 = pi r^2 = pi
Total area = A1+A2+A3 = 2sqrt(5) (pi^2) + 22pi + pi
= 2sqrt(5) pi^2 + 23pi

Which equation of the line passes through the point (0,4) and is perpendicular to the lines whose equation is y=-1/2x + 3
Answer:
y = 2x+4
Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

Consider the given function. Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry of the function.
Answer:
Following are the solution to the gvien question:
Step-by-step explanation:
Let the quadratic equation is:
[tex]\to h(x) = (x + 1)^2 - 4[/tex]
vertex is:
[tex]\to h(x) = a(x -h)^2 + k[/tex]
(h) = axis of symmetry
(h,k) = vertex.
By using the given equation:
[tex]h(x) = (x - (-1))^2 - 4[/tex]
Hence,
[tex]h = -1 \\\\ k = -4[/tex]
line of symmetry [tex]x = -1[/tex]
vertex is [tex](h,k) = (-1,-4)[/tex]
finding the x intercept:
[tex](x + 1)^2 = 4\\\\\sqrt{(x + 1)^2} = \sqrt{4}\\\\x + 1 = \pm 2\\\\x = 2-1 \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-2 -1\\\\x = 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-3\\\\[/tex]
x -intercepts -3,1
Calculating the y-intercept when x = 0 putting into the real equation:
[tex]h(x) = (0 +1)^2 - 4 \\\\y = 1 - 4\\\\y = -3[/tex]

Function Q: y =1/3x + 2 Identify function Q as linear or nonlinear. State a reason why it is linear or nonlinear.
Answer:
A linear function is written in slope-intercept form as:
y = a*x + b
Where a is the slope and b is the y-intercept.
So any function of this shape, is a linear function, such that when graphed it is a straight line.
In this case, the function you wrote is:
Q: y = 1/3x + 2
Now, if the function is exactly what you wrote, then x is in the denominator:
y = 1/(3*x) + 2
Clearly, this is different than the general linear equation you can see above (here the variable is in the denominator) then in this case Q is non-linear.
If instead, the actual function Q is:
Q: y = (1/3)*x + 2
Then this is a linear equation, where the slope is 1/3 and the y-intercept is 2.
