The population of Kenya was 45.1 million in 2009 and has been growing by 2.3% each year. If this trend continues, in what year will the population exceed 52.2 million?
Answer:
6.4294 years
Step-by-step explanation:
45.1 million in 2009 -- 2.3% each year
In what year will the population exceed 52.2 million?
We use exponential growth formula
ξ(t) = y = ab^t
a = 45.1, b = 1+ξ, ξ= 2.3%, ξ(t) = 52.2
52.2/45.1 = (1.023)^t
We take log both side
Log(1.15742794) = tlog(1.023)
0.0634939619 = t0.00987563371
t = 0.0634939619/0.00987563371
t = 6.429355701569454
t = 6.4294 years

X/5 + 6 = 10
44
30
20
-20
Answer:
x = 20
Step-by-step explanation:
The way to solve these problems is by isolating x (getting it by itself on one side).
So let's look at the operations needed! First of all, there's currently a +6 hanging out next to x. We don't want that, so we subtract 6 from both sides.
x/5 + 6 = 10
-6 -6
x/5 = 4
We now see that x is being divided by five. To get just x, we can now multiply both sides by five to get rid of that fraction.
x/5 = 4
*5 *5
x = 20

how to calculate directly propotonal
Answer: Direct Proportion
In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x” where k is constant in the equation. Example: y is directly proportional to x, when x = 15, y = 30.

Step-by-step explanation:• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.
• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.
• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
• When we are not given a number for the variable in the expression, we have to group like-terms.
Example: 5x + 6 + 3x - 2 - y1st: group 5x and 3x (add the terms together) = 8x2nd: group 6 and -2 (add the terms together) = 43rd: Since -y has no like-terms, we can't group it = -yFourth, put the terms in order (variables = alphabetical order and then numbers) = 8x - y + 41. 4x + 12 - 3x + 8
4x - 3x = 1x = x12 + 8 = 20x + 202. -8x + 1 + 2x - 1 + 6x
-8x + 2x + 6x = -8x + 8x = 01 - 1 = 003. 4x - 3 - 2x - 5
4x - 2x = 2x-3 - 5 = -82x - 84. 100x + 5 - 5x + 5
100x - 5x = 95x5 + 5 = 1095x + 105. -4x - 4 - 2 - 5x
-4x - 5x = -9x-4 - 2 = -6-9x - 66. 2x - 1 + 2x - 4 + y
2x + 2x = 4x-1 - 4 = -54x + y - 57. 5y - x + 2y - y + 5
5y + 2y - y = 5y + 1y = 6y-x + 6y + 58. -15 + 3y - 3x - 2y + 4x
3y - 2y = 1y = y-3x + 4x = 1x = xx + y - 159. 4 - 3y + 3x - 2x - y
-3y - y = 4y3x - 2x = 1x = xx + 4y + 4Hope I helped you, if I did can you please mark me the Brainliest?

Which congruence theorems can be used to prove AABR = AACR? Select three options.
A. HL
B. AS
C. SSS
D. ASA
E. AAS
Answer:
HL, SAS, ans SSS
Step-by-step explanation:
ASA and AAS cannot be used because we can only confirm one angle of each triangle.
Congruent shapes have equal corresponding sides and angles.
The congruence theorems that can be used to prove [tex]\triangle ABR \cong \triangle ACR[/tex] are HL, SAS, and SSS
[tex]\triangle ABR \cong \triangle ACR[/tex] means that, the triangles are congruent.
From the attached figure, we have the following congruent sides and angle:

Answer:
[tex]x = \frac{ \sqrt{6} }{2} [/tex]
[tex]y = \frac{3 \sqrt{2} }{2} [/tex]
Step-by-step explanation:
[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \tan(theta) = \frac{opposite}{adjacent} [/tex]
theta = 30°
hypotenuse = √6
opposite = x
adjacent = y
1) find x using the sin formula[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(30) = \frac{x}{ \sqrt{6} } [/tex]
[tex] \sin(30) \times \sqrt{6} = x[/tex]
[tex] \frac{ \sqrt{6} }{2} = x[/tex]
[tex]x = \frac{ \sqrt{6} }{2} [/tex]
2) find y using the cos formula[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \cos(30) = \frac{y}{ \sqrt{6} } [/tex]
[tex] \cos(30) \times \sqrt{6} = y[/tex]
[tex] \frac{3 \sqrt{2} }{2} = y[/tex]
[tex]y = \frac{3 \sqrt{2} }{2} [/tex]

Step-by-step explanation:
27b -3 - 14b -21 = 0
13b - 24 = 0
13b = 24
b = 24/13 or 1.8

D) Dilations are a type of transformation

Answer:
B) Dilations increase angle measures.
Step-by-step explanation:
Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.
The false statement is B.
