Answer:
k=9
Step-by-step explanation:
First find r=22/20=1.1
The sum of the first k terms formula is a1•(1-r^k)/(1-r)
a1=20 and the sum is 271.59
Now plug in these values in the formula and find k.
271.59=20(1-1.1^k)/(1-1.1)
When you simplify this equation, you will get k=ln(2.358)/ln(1.1)
k=9

What is the solution to the equation g^(x-2)=27
Answer:
First problem: Solving for g.
[tex]g=27^{\frac{1}{x-2}}[/tex]
Second problem: Solving for x.
[tex]x=\log_g(27)+2[/tex]
Third problem: Assuming g is 9 while solving for x.
[tex]x=3.5[/tex]
Step-by-step explanation:
First problem: Solving for g.
[tex]g^{x-2}=27[/tex]
Raise both sides by 1/(x-2).
[tex](g^{x-2})^{\frac{1}{x-2}}=27^{\frac{1}{x-2}}[/tex]
[tex]g^{1}=27^{\frac{1}{x-2}}[/tex]
[tex]g=27^{\frac{1}{x-2}}[/tex]
Second problem: Solving for x.
[tex]g^{x-2}=27[/tex]
x is in the exponent so we have to convert to logarithm form since we desire to solve for it:
[tex]\log_g(27)=x-2[/tex]
Add 2 on both sides:
[tex]\log_g(27)+2=x[/tex]
[tex]x=\log_g(27)+2[/tex]
Third problem: Assuming g is 9 while solving for x.
[tex]9^{x-2}=27[/tex]
I'm going to solve this in a different way than I did above but you could solve it exactly the way I did for x when 9 was g.
I'm going to write both 9 and 27 as 3 to some power.
9=3^2 while 27=3^3.
[tex](3^2)^{x-2}=3^3[/tex]
[tex]3^{2x-4}=3^3[/tex]
Since both bases are the same on both sides, we need the exponents to be the same:
[tex]2x-4=3[/tex]
Add 4 on both sides:
[tex]2x=7[/tex]
Divide both sides by 2:
[tex]x=\frac{7}{2}[/tex]
[tex]x=3.5[/tex]
Now earlier for x in terms of g we got:
[tex]x=\log_g(27)+2[/tex]
I we input 9 in place of g and put it into our calculator or use some tricks without the calculator to compute we should get 3.5 as the answer like we did above when g was 9.
[tex]x=\log_9(27)+2[/tex]
[tex]x=\frac{3}{2}+2[/tex]
[tex]x=1.5+2[/tex]
[tex]x=3.5[/tex]

Identify the radius and the center of a circle whose equation is (x - 5)2 + y2 = 81.
The radius of the circle is
The center of the circle is at (1
units.
Answer:
The center is (5,0) and r=9.
Step-by-step explanation:
The standard form of a circle is [tex](x-h)^2+(y-k)^2[/tex] where (h,k) is the center and r is the radius.
On comparing your equation of
[tex](x - 5)^2 + (y-0)^2 = 9^2[/tex], we should see that h=5,k=0, and r=9.
The center is (5,0) and r=9.
Answer:
The center is at (5,0) and the radius is 9
Step-by-step explanation:
(x - 5)^2 + y^2 = 81.
An equation for a circle can be written in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
Rewriting the equation
(x - 5)^2 + y^2 = 81.
(x - 5)^2 + (y-0)^2 = 9^2
The center is at (5,0) and the radius is 9
Given the directrix of y = 4 and focus of (0, 2), which is the equation of the parabola? y = one fourthx2 + 3 y = −one fourthx2 + 3 y = −one fourthx2 − 3 y = one fourthx2 − 3
Answer:
y = - [tex]\frac{1}{4}[/tex] x² + 3
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and directrix.
Using the distance formula
[tex]\sqrt{(x-0)^2+(y-2)^2}[/tex] = | y - 4 |, that is
[tex]\sqrt{x^2+(y-2)^2}[/tex] = | y - 4 |
Squaring both sides
x² + (y - 2)² = (y - 4)² ← distribute parenthesis
x² + y² - 4y + 4 = y² - 8y + 16 ( subtract y² - 8y from both sides )
x² + 4y + 4 = 16 ( subtract x² + 4 from both sides )
4y = - x² + 12 ( divide both sides by 4 )
y = - [tex]\frac{1}{4}[/tex] x² + 3

Step-by-step explanation:
A metal worker has several 1-kilogram bars of a metal alloy that contain 23% copper and several 1-kilogram bars that contain 79% copper. How many bars of each type of alloy should be melted and combined to create 48 kilograms of a 44% copper alloy?
Answer:
30 each of 23% bars and 18 each of 79% bars
Step-by-step explanation:
If x is the number of 1 kg 23% copper bars, and y is the number of 1 kg 79% copper bars, then:
x + y = 48
0.23x + 0.79y = 0.44(48)
Substituting and solving:
0.23x + 0.79(48-x) = 0.44(48)
0.23x + 37.92 - 0.79x = 21.12
16.8 = 0.56x
x = 30
y = 48 - x
y = 18
You need 30 each of 23% bars and 18 each of 79% bars.

Find the distance between the points (9,6) and (-4,7)
Answer:
[tex]\large\boxed{\sqrt{170}}[/tex]
Step-by-step explanation:
The formula of a distance between two points:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have the points (9, 6) and (-4, 7). Substitute:
[tex]d=\sqrt{(-4-9)^2+(7-6)^2}=\sqrt{(-13)^2+1^2}=\sqrt{169+1}=\sqrt{170}[/tex]
The distance between the points (9,6) and (-4,7) can be found using the distance formula. By inputting the given coordinates into the formula, we find that the distance is √170 units.
Explanation:The question is asking us to find the distance between two given points, (9,6) and (-4,7). In mathematics, this is commonly done using the distance formula: √[(x₂-x₁)² + (y₂-y₁)²]. Here, coordinates (x₁,y₁) are (9,6) and (x₂,y₂) are (-4,7).
Substituting these values into our formula, we have: Distance = √[(-4-9)² + (7-6)²] = √[(-13)² + 1²] = √[169 + 1] = √170.
Therefore, the distance between the points (9,6) and (-4,7) is √170 units.

It needs to be greater than 4 or less than -4 in order for the absolute value to be greater than 7, so you're good.
If “u” varies directly with “v,” and u = 6 when v = -7, what’s is “u” when v = 4?
U=__
In a scenario where 'u' varies directly with 'v', the constant of variation, k is found by: k=u/v. Here, k becomes 6/-7. If we want to know the value for 'u' when v=4, we use the calculated k in our formula, resulting in u=4*(6/-7) which equals -24/7.
Explanation:The question is about the direct variation between two quantities 'u' and 'v'. If 'u' varies directly with 'v', it means that multiplying or dividing one quantity will have the same effect on the other. We use the mathematical formula for direct variation to find the values: 'u' = kv, where k is the constant of variation.
So, we first find 'k' when u = 6 and v = -7. From our formula, k = u/v = 6/-7.
When we know the k, we can find u' when v = 4. Using the formula, 'u' = kv = 4 * (6/-7) = -24/7.

Here's a graph of a linear function. Write the
equation that describes that function.
Express it in slope-intercept form.
Answer:
y = -3x+4
Step-by-step explanation:
Slope intercept form of a line is given by y = mx + b
Where
m is the slope
b is the y intercept.
To find m, we need to take any arbitrary 2 points and see how many units up/down and how many units right/left we need to go from one to another. Basically change in y by change in x.
Let's take 2 arbitrary points: (0,4) & (2,-2)
So we need to go -6 units from y = 4 to y = -2. We need to go 2 units from x = 0 to x = 2.
Hence slope is change in y by change in x, which is -6/2 = -3
b is the y-interceept, the place where it cuts the y axis. Looking at the graph, it is at y = 4
Now we can write the equation as :
y = -3x+4

By manipulating algebraically we have:
[tex]x ^ 2 + x-5 = 0[/tex]
The quadratic formula is given by:
[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]

[tex]x = \frac {-1 \pm \sqrt {1 ^ 2-4 (1) (- 5)}} {2 (1)}\\x = \frac {-1 \pm \sqrt {1 + 20}} {2}\\x = \frac {-1 \pm \sqrt {21}} {2}[/tex]
So, we have two roots:
[tex]x_ {1} = \frac {-1+ \sqrt {21}} {2} = 1,7913\\x_ {2} = \frac {-1- \sqrt {21}} {2} = - 2.7913[/tex]

What is 12x - 4y = -8 written in slope-intercept form?
y = 3x+2
y= 3x-2
y = 12x-8
y=-12X-8
Hey there!
Isolate the y variable by subtracting 12x in both sides:
-4y = -12x - 8
To solve for y divide -4 in both sides
y = 3x + 2
Our answer would be y = 3x + 2
Answer:
y = 3x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 12x - 4y = - 8 into this form
Subtract 12x from both sides
- 4y = - 12x - 8 ( divide all terms by - 4 )
y = 3x + 2 ← in slope- intercept form
the graphs of 2x+3Y=5 and 3x+y=18 contain two sides of a triangle. a vertex of the triangle is at the intersection of the graphs. what are the coordinates of the intersection?
Answer:
(7, - 3 )
Step-by-step explanation:
Solve the 2 equations simultaneously to find intersection.
Given the equations of the sides
2x + 3y = 5 → (1)
3x + y = 18 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the y- term
- 9x - 3y = - 54 → (3)
Add (1) and (3) term by term
(2x - 9x) + (3y - 3y) = (5 - 54) and simplifying gives
- 7x = - 49 ( divide both sides by - 7 )
x = 7
Substitute x = 7 into (1) or (2) for corresponding value of y
Substituting in (2)
21 + y = 18 ( subtract 21 from both sides )
y = - 3
Point of intersection = (7, - 3 )
Final Answer:
The coordinates of the intersection of the two lines are (x, y) = (7, -3).
Explanation:
To find the coordinates of the intersection of the two lines represented by the equations 2x + 3y = 5 and 3x + y = 18, we can solve this system of linear equations. Here's how to proceed step-by-step:
Step 1: Label the equations.
Let's call the first equation (1) and the second equation (2) for easy reference.
(1) 2x + 3y = 5
(2) 3x + y = 18
Step 2: Solve one of the equations for one of the variables.
Let's solve equation (2) for y:
y = 18 - 3x
Step 3: Substitute the expression for y in equation (1).
Now we substitute y in equation (1) with the expression we got from equation (2):
2x + 3(18 - 3x) = 5
Simplify the equation:
2x + 54 - 9x = 5
Combine like terms:
-7x + 54 = 5
Step 4: Simplify the equation for x.
Now we isolate x:
-7x = 5 - 54
-7x = -49
Divide both sides by -7 to find x:
x = -49 / -7
x = 7
Step 5: Substitute the value of x back into the equation for y.
We already have the expression for y from step 2 which was y = 18 - 3x. Now we substitute x = 7 into this expression to get y:
y = 18 - 3(7)
y = 18 - 21
y = -3
Step 6: State the coordinates of the intersection.
The coordinates of the intersection of the two lines are (x, y) = (7, -3).
Therefore, the vertex of the triangle at the intersection of the two graphs is at the point (7, -3).
