Complete the equation of the line through (2, -2) and (4, 1)
Answer:
y=1.5x-5
Step-by-step explanation:
Please help me with this
Given:
The equation is:
[tex]3^x\times 9=3^{2n-1}[/tex]
To find:
The value of n in terms of x.
Solution:
We have,
[tex]3^x\times 9=3^{2n-1}[/tex]
It can be written as
[tex]3^x\times 3^2=3^{2n-1}[/tex]
[tex]3^{x+2}=3^{2n-1}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
On comparing the exponents, we get
[tex]x+2=2n-1[/tex]
Add 1 on both sides.
[tex]x+2+1=2n-1+1[/tex]
[tex]x+3=2n[/tex]
Divide both sides by 2.
[tex]\dfrac{x+3}{2}=n[/tex]
Therefore, the value of n is terms of x is [tex]n=\dfrac{x+3}{2}[/tex].
how do I solve this using the Pythagorean theorem
Answer:
x=3
Step-by-step explanation:
First would need to convert the radical into a number.
And since if you have a perfect square of a radical it goes outside the square root sign, you would take the 3 and square it to make 9 and then take the 2 inside the square root sign and multiply so you have the square root of 18|
Since we have [tex]\sqrt{18}[/tex] as the Leg c we would need to square it, squaring a square root sign would just cause them to be cancelled out and you being left with 18, afterwards find the square of 3, which is 9
18-9=9
square root of 9 = 3
During a walk-a-thon, Noah's time in hours, t, and distance in miles, d, are related by the equation ⅓ d = t. A graph of the equation includes the point (12, 4). Identify the independent variable. What does the point (12, 4) represent in this situation? What point would represent the time it took to walk 7 ½ miles?
Answer:
The Indapendent virable is: t
Noah took 4 hours to walk 12 miles
(7 1/2, 2 1/2)
Step-by-step explanation:
I hope this is right!
The point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
The independent variable in this situation is time (t).
Point (12, 4) represents that Noah walked for 4 miles in 12 hours.
To find the point that represents the time it took to walk 7 ½ miles, we need to solve for t in the equation ⅓ d = t.
Substituting d = 7.5, we get:
⅓ (7.5) = t
Simplifying, we get:
t = 2.5
Therefore, the point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).

From the simultaneous linear equation, we have the coefficient matrix as;
(3 4 5)
(2 -1 8)
(5 -2 7)
The x-matrix is Dx is given by;
(18 4 5)
(13 -1 8)
(20 -2 7)
Similarly, the y-matrix Dy is given by;
(3 18 5)
(2 13 8)
(5 -20 7)
Also,the z-matrix Dz is given by;
(3 4 18)
(2 -1 13)
(5 -2 -20)
Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136

The length of a rectangle is 36
centmeters and the width is 9
centimeters. A similar rectangle has
a width of 3 centimeters.
what is
the length of the decond triangle?
Answer: 12cm
Step-by-step explanation:
They are similar, so we can set an equation of:
the ratio of length and width of the big triangle equal to the ratio of length and width of the small(second) triangle.
36:9 = x:3
36/9 = x/3
9x = 3(36) by use the cross multiply
9x = 108
x = 12 cm

Answer:
La Provincia del Guayas comprime el 25.1% de la población de Ecuador. A su vez, la Ciudad de Guayaquil tiene una población igual al 15.58% de la población ecuatoriana.
Step-by-step explanation:
Dado que vivo en la Provincia del Guayas, y en la ciudad de Guayaquil, los datos de población solicitados son los siguientes:
-Provincia del Guayas: 4.387.434 habitantes, es decir, un 25.1% del total de la población de Ecuador, que es de 17.475.570 habitantes, conforme surge del siguiente calculo:
17.475.570 = 100
4.387.434 = X
4.387.434 x 100 / 17.475.570 = X
438.743.400 / 17.475.570 = X
25,10 = X
-Ciudad de Guayaquil: 2.723.665 habitantes, es decir, un 15.58% del total de la población de Ecuador, conforme surge del siguiente cálculo:
17.475.570 = 100
2.723.665 = X
2.723.665 x 100 / 17.475.570 = X
272.366.500 / 17.475.570 = X
15.58 = X

A story owner wants to prepare 100 lb of a candy mix that she will she for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost?
Answer:
1.65
Step-by-step explanation:
100 pounds of the mixture = 1.36 * 100 = 136 dollars.
She uses 20 pounds of jelly beans that cost
20 * .20 = 4.00
136 - 4 = 132 dollars left for 80 pounds of sugar candies.
80 pounds = 132 pounds of sugar candies.
1 pound = x
80/1 = 132 / x Cross multiply
80x = 132
x = 132 / 80
x = 1.65 / per pound

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 ⅗ door. How many liters of paint are needed for 1 door?
Answer: 1.25 litres
Step-by-step explanation:
Two litres of paint is sufficient to paint 1 ⅗ doors.
To find out the amount of paint needed to paint one door, you can use direct proportion:
2 litres : 1 ⅗ door
x 1 door
Cross multiply to get:
1 ⅗ x = 2
x = 2 / 1 ⅗
x = 2 ÷ 8/5
x = 2 * 5/8
x = 1.25 litres

Answer:
If the weight of the equipment is 20oz, then the total weight of the package is 23 oz.
Step-by-step explanation:
The value of the variable p determines the package's overall weight. The true statement in the scenario given is provided by: Option 3: If the equipment weighs 20 oz, the package will weigh a total of 23 oz.
What is relationship between two variables?To examine if there is a relationship between the two variables in the tabular data, we can try fitting a curve to the data between the two variables.
Depending on the situation, there may be an exact relationship, a loose connection (measured by correlation or polynomial regression that fits), or even complete independence.
For the given case, two variables in consideration are:
w = weight of equipment (oz, it means weight is calculated in oz units).
p = total weight of package (in oz)
From the table, we can see that for each value of w, the value of p is 3 more than whatever value of w is there.
Thus, the correct option is 3.

Answer:
=50.29
Step-by-step explanation:
The perimeter of a circle is also called the circumference
C = 2 * pi *r
25 1/7 = 2 * 22/7 *r
Rewriting as an improper fraction on the left
(25*7 +1)/7 = 44/7 *r
176/7 = 44/7 r
Multiplying each side by 7/44
7/44 *176/7 = 7/44 *44/7 r
4 = r
We can now find the area by
A = pi r^2
A = (22/7) * 4^2
A = 22/7 * 16
=352/7

A search and rescue drone can scan 0.5 hectare in 2 minutes. How many hectares per minute can the drone scan? 5/10 ha | 2 min = 5/10×2/1 yes or no
Answer:
Drone will take 0.25 hectare per minute to scan the area.
Step-by-step explanation:
By using unitary method,
A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.
Area scanned by the drone in 1 minute = [tex]\frac{\text{Total area scanned}}{\text{Total time taken}}[/tex]
= [tex]\frac{0.5}{2}[/tex]
= 0.25 hectare per minute
Therefore, drone will take 0.25 hectare per minute to scan the area.

Answer:
22,000 miles
Step-by-step explanation:
Circumference of a circle: 2πr (r is the radius)
Substitute the length of the radius given, which is 3500. Also, substitute the approximate value of π, which is 3.14.
Circumference = 2 * 3.14 * 3500
Circumference = 21980
This rounds to about 22,000, so the answer is 22,000 miles.
I hope this helps! Feel free to ask any questions!
Answer: 22,000 miles
Step-by-step explanation:
Circumference of circle = 2πr
2 × 22/7 × 3500
22/7 × 3500 = 11000
2 × 11000 = 22000
The circumference would be 22,000 miles.
OR
Circumference of circle = 2πr
2 × 3.14 × 3500
6.28 × 3500 = 21,980
21980 to the nearest 1000 is 22000
The circumference would be approximately 22,000 miles.
