Answer:
y = 2x + 3
Step-by-step explanation:
Given:
(2, 7) and (0, 3)
Find the slope between the two points:
(x1, y1) = (0, 3)
(x2, y2) = (2, 7)
(y2 - y1)/(x2 - x1)
(7 - 3)/(2 - 0)
4/2 = 2
m = 2
y = mx + a
y = 2x + a
Use one of the two points to find a (I will use point (2, 7):
7 = 2(2) + a
7 = 4 + a
a = 3
Slope-intercept Form: y = 2x + 3
Point-slope Form: y - 3 = 2x
Point-slope Form: y - 7 = 2(x - 2)
General equation: 2x - y + 3 = 0
In ΔDEF, e = 8.7 inches, ∠F=8° and ∠D=34°. Find the length of f, to the nearest 10th of an inch.
Answer:
Step-by-step explanation:
The length of f to the nearest 10th of an inch is 1.8 inches.
What is Law of Sines?Law of sines is defined as that ratio of the length of the sides of a triangle to the sine of the angle opposite to the these sides are equal.
That is, if a, b and c are sides opposite to the angles A, B and C respectively, then,
a / sin A = b / sin B = c / sin C
Given a triangle DEF.
The angles are given as, ∠F = 8° and ∠D = 34°.
We know,
Sum of the interior angles of a triangle = 180°
∠E = 180 - (8 + 34) = 138°
Using the law of sines,
f / sin F = e / sin E
f = (e / sin E) sin F
Substituting,
f = (8.7 / sin 138) sin 8
= 13.0019 × 0.1392
= 1.809
≈ 1.8
Hence the length of f to the nearest 10th of an inch is 1.8 inches.

The highway loop around a major city can be modeled by a circle with a circumference of 53 miles. The
distance across the city represents the diameter of the circle. Which distance is closest to the distance
across the city?
A. 106 miles
B. 53 miles
C. 27 miles
D. 17 miles
Answer:
[tex]D = 17\ miles[/tex]
Step-by-step explanation:
Given
[tex]Circumference\ (C) = 53\ miles[/tex]

The function f(x) = x is translated using the rule (x, y) - (x - 6, y + 9) to create A(x).
Which expression describes the range of A(x)?
Oy2-9
Oy6
Oy26
O y29
It seems the correct function you need to mention is f(x) = sqrt x
so, I am assuming [tex]f(x) = \sqrt{x}[/tex] and will solve the question based on it.
Answer:
Check the explanation
Step-by-step explanation:
Given the function
[tex]f(x) = \sqrt{x}[/tex]
As the function is translated according to the rule
(x, y) → (x - 6, y + 9)Translation of the function [tex]f(x) = \sqrt{x}[/tex] 6 units to the left will bring the function
[tex]g(x) = \sqrt{x+6}[/tex]
Translation of the function [tex]g(x) = \sqrt{x+6}[/tex] 9 units up will bring the function
[tex]A\left(x\right)=\sqrt{x+6}+9[/tex]
Determining the range of [tex]A\left(x\right)=\sqrt{x+6}+9[/tex]
As we know that the range is the set of dependent values for which the function is defined.[tex]\mathrm{The\:range\:of\:an\:radical\:function\:of\:the\:form}\:c\sqrt{ax+b}+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k[/tex]
[tex]k=9[/tex]
[tex]f\left(x\right)\ge \:9[/tex]
so
[tex]\mathrm{Range\:of\:}\sqrt{x+6}+9:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:9\:\\ \:\mathrm{Interval\:Notation:}&\:[9,\:\infty \:)\end{bmatrix}[/tex]
Therefore, the expression describes the range of A(x) will be:
[tex]f\left(x\right)\ge \:\:9\:or\:y\:\ge \:\:\:9[/tex]

Alan is building a fence around his fish pond. The fish pond is in the shape of a rectangle with a length of 60 feet and a width of 40 feet. It took alan 16 hours to complete the fencing. What is the unit rate at which alan put fence around his fish pond
Answer:
12.50 ft per hour
Step-by-step explanation:
Given that:
Fish pond has a rectangular shape.
Length of fish pond = 60 feet
Width of fish pond = 40 feet
Total time to complete the fencing = 16 hours
To find:
Unit rate of putting the fencing around the fish pond.
Solution:
First of all, we need to find the total fencing to be put around the fish pond.
Total fencing is nothing but the perimeter of the fish pond which is of rectangular shape.
Formula for perimeter of rectangular shape is given as:
[tex]Perimeter = 2\times (Length + Width)[/tex]
[tex]Perimeter = 2\times (60+40)\\\Rightarrow Perimeter = 200\ ft[/tex]
Unit rate is the perimeter divided by total time taken to put the fencing around.
Therefore,
Unit rate = [tex]\frac{200}{16} = \bold{12.5}[/tex] feet per hour
So, the answer is 12.5 feet per hour.

The probability that it will rain on 'Hari Merdeka' is 2/15.Find the probability that will be no rain on 'Hari Merdeka'.
The probability it will rain of Hari Merdeka is 2/15. Since you are finding the probability that will be no rain on Hari Merdeka, you also need to find the part of 15/15 that is not 2/15. You can do this by subtracting.
15/15-2/15=13/15.
The probability that will be no rain on Hari Merdeka is 13/15.

The sum of two numbers is 12. Three times the smaller number increased by the larger number is 20 . Find the numbers .Write the solution
Answer:
In these types of algebra problems where we are given numbers that are "unknown" and asked to find them, it is a good idea to give them names.
Let the larger number be X.
Let the smaller number be Y.
If the larger number is three times the smaller number, we can use this information to write an equation, using our labels for the two unknown numbers. See how I translate this sentence into an equation:
The larger number is three times the smaller number.
X = 3 * Y
X = 3*Y
We've got one equation down. Since we have two variables, we're going to need two equations to solve for both of them.
The sum of two numbers is twenty-four.
X + Y = 24
X+Y = 24
But, from our previous equation, we know that X is the same as 3*Y. This allows us to substitute "X" with "3*Y" in our second equation since the two are equal according to the first equation.
(3*Y) + Y = 24.
3Y + Y = 24
4Y = 24
4Y / 4 = 24/4
Y = 6
Now we've got the value of the smaller number. Let's plug it into our first equation,
X = 3*Y.
X = 3*(6)
X = 18
We can check our work by plugging both values into both equations and seeing if they work out:
6+18 = 24
6*3 = 18
So our bigger number is 18, and our smaller number is 6.
Hope it helps!
