The population of North Carolina will reach 12 million in the year 2028.
What is Population Growth?Population growth is defined as the increase in the number of people which is calculated using population growth rate.
Given that,
Population in 2010 = 9.5 million
Population is increasing to 1.3% per year.
Annual growth rate = 1.3% = 1.3/100 = 0.013
We have the population growth formula,
P = P₀ e^(r t)
Here, P₀ = 9.5 million = 9,500,000
and P = 12 million = 12,000,000
r = 0.013
We have to find t.
12,000,000 = 9,500,000 e^(0.013t)
120 / 95 = e^(0.013t)
Taking natural logarithm on both sides and also ㏑(e^m) = m ㏑ e, we get,
㏑(12/9.5) = 0.013t × ㏑e
[㏑(12/9.5) ÷ 0.013] = t [since ln e = 1]
t = 17.97 ≈ 18 years
The year is 2010 + 18 = 2028
Hence in the year 2028, the population will be 12 million.

What is the length x of a diagonal support, to the nearest tenth of a foot?
CORRECT ANSWER
PROVIDE EXPLANATION
The length of x of a diagonal support is 13.8 feet.
What is the hypotenuse of a triangle.The hypotenuse of a triangle is the length of the longest side of the triangle. So that it is always opposite to the measure of the largest angle of a triangle.
In the question given, divide the length of the footbridge into 2 parts.
So that,
Half of the footbridge = 25/ 2
= 12.5 ft
So that applying the appropriate trigonometric function to determine the value of x using any of the congruent triangles. We have;
Sin θ = opposite/ hypotenuse
Sin 65 = 12.5/ x
x = 12.5/ Sin 65
= 12.5/ 0.90631
x = 13.792 feet
The length x of a diagonal support is 13.8 feet.

How do you identify inequalities?By drawing a straight line and designating the end points with either an open circle or a closed circle, we can depict inequalities on a number line by illustrating the range of integers. An open circle indicates that it excludes the value. A closed circle indicates that it does contain the value.
Both equations and inequalities are mathematical phrases created by connecting two expressions. The equal sign (=) in an equation denotes that the two expressions are regarded as equal. In contrast, an inequality indicates that the two phrases are not always equal by using the symbols >,,, or.

Write an equation in standard form passing through the given point and parallel to the given line: (-1,-1) y = - x - 5
A: x - y = -2
B: x + y = 0
C: x - y = 0
D: x + y = -2
Option D, x + y = -2 is the equation in standard form passing through the (-1,-1) and parallel to y = -x - 5.
What is standard form?The process of expressing a specific element in mathematics in the most typical way is known as standard form. Every element of mathematics, including big and small numbers, equations and lines, is designated in a standard form.
A standard form is a way of expressing a certain mathematical idea, such as an equation, number, or expression, in a way that adheres to a set of rules. The standard form is used to clearly represent extremely large or extremely small numbers.
To write an equation in standard form passing through the (-1,-1) and parallel to y = - x - 5, we need to find y-intercept form first
We know that parallel lines have same slope, so
y - y1 = m(x - x1)
y -(-1) = -1(x -(-1)
y + 1 = -x - 1
y = -x - 2
y + x = -2
Thus, Option D, x + y = -2 is the equation in standard form passing through the (-1,-1) and parallel to y = -x - 5.

After evaluating the given expressions the results could be 245 / 89 , 43/6, 33/4 .
What is expression ?
expression can be defined as with the minimum of two variables or numbers and at least one math operation.
Given that ,
7/ 8 * 14 / (3/8 * 6 ) + 2 1/5
= (7/8 * 14 )/ ((18 / 8) + 11/5)
= (98/ 8 ) / (90 + 88) / 40
= (98/ 8 ) / (178/ 40)
= (98 * 40) / (8* 78)
= 245/89
Hence the final value could be 245/53.
7/ 8 + (6*7/8 - 4 * 3/16 ) / (3/4 )
(7/8 + (21/4 - 3/4 ) ) / (3/4)
(7/8 + 18/4) / (3/4)
(43/8) / (3/4)
43/6
Hence the final value could be 43/6.
3 1/7 * (3 1/3 * (2/3 + 1/6 ) - 5/18 ) / 2 (3/7)
11/7 * (10/6 - 5/18) / (17/7)

How do i solve thissssssss
[tex]\dfrac{s}{4} +5=13[/tex]
Simplify:
[tex]\dfrac{1}{4} s+5=13[/tex]
Subtract 5 from both sides:
[tex]\dfrac{1}{4} s+5-5=13-5[/tex]
[tex]\dfrac{1}{4} s=8[/tex]
Multiply both sides by 4:
[tex]4\times(\dfrac{1}{4} s)=4\times(8)[/tex]
[tex]\fbox{s = 32}[/tex]
s = 32.
Step-by-step explanation:1. Write the expression.[tex]\frac{s}{4} +5=13[/tex]
2. Subtract 5 from both sides of the equation.[tex]\frac{s}{4} +5-5=13-5\\ \\\frac{s}{4} =8[/tex]
3. Multiply by "4" on both sides of the equation.[tex]\frac{s}{4}*4 =8*4\\ \\s=32[/tex]
4. Verify.If the result is correct, then the equation should return the same value of both sides of the equal symbol (=) when we substitute the variable "s" by it's calculated value, 32.
[tex]\frac{(32)}{4} +5=13\\ \\8+5=13\\ \\13=13[/tex]
As you can tell, the same number appears on both sides of the equal symbol, this means that the result is correct!
