Given:
A figure of a triangle.
To find:
The value of g.
Solution:
Law of Cosines:
[tex]a^2=b^2+c^2-2bccosA[/tex]
Using the Law of Cosines for the given triangle, we get
[tex]g^2=8^2+7^2-2(8)(7)cos(65^\circ)[/tex]
[tex]g^2=64+49-112(0.4226)[/tex]
[tex]g^2=113-47.3312[/tex]
[tex]g^2=65.6688[/tex]
Taking square root on both sides.
[tex]g=\sqrt{65.6688}[/tex]
[tex]g=8.10363[/tex]
[tex]g\approx 8.10[/tex]
Therefore, the value of g is about 8.10 units.

Solve this equation:
1 - (x-4) = 2x + 2(x - 5)
a. 5
b. 3
c. 1
d. 4
Answer:
The answer is 3
Step-by-step explanation:
The answer is 3 because x= 15/5 = 3
Write an equation for the data in the table. Identify your variables.
First find the slope m. slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
Let's use (0, -20) for x1 and y1; and (2, 10) for x2 and y2
[tex]\frac{10-(-20)}{2-0}[/tex] = [tex]\frac{30}{2}[/tex] = [tex]15[/tex]
Now find the y-intercept: the point where the graph crosses the y-axis. The y intercept always has an x value of 0. So -20 is the y-intercept
Use the slope formula [tex]y = mx + b[/tex]. Slope=m, y-intercept = b
y = 15x - 20
y is the money in the bank account in dollars
x is the day
Convert 639 into quinary system
Step-by-step explanation:
To convert decimal number 639 to quinary, follow these steps:
Divide 639 by 5 keeping notice of the quotient and the remainder.Continue dividing the quotient by 5 until you get a quotient of zero.Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 639.Using the above steps, here is the work involved in the solution for converting 639 to quinary number:639 / 5 = 127 with remainder 4127 / 5 = 25 with remainder 225 / 5 = 5 with remainder 05 / 5 = 1 with remainder 01 / 5 = 0 with remainder 1Then just write down the remainders in the reverse order to get the answer, The decimal number 639 converted to quinary is therefore equal to :

The perimeter of an equilateral triangle is 12\/3 cm. Find the radius, apothem and area of the equilateral triangle.
Answer:
Radius - 4
Apothem - 2
Area - [tex]12\sqrt{3}[/tex] or 20.8
Step-by-step explanation:
Try to draw out my explanation so you know what this looks like.
~~~~
This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...
[tex]12\sqrt{3} \div3 = 4\sqrt{3}[/tex]
Now that we know the side lengths, we can get this started!
~~~~
Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.
4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.
[tex]Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6[/tex]
By the way, the formula for the area can be either of the two:
[tex]A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS[/tex]
we can easily find the area using the first formula.
[tex]A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}[/tex]
The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...
So we can divide the big triangle into a mini triangle at the bottom left/right
The height (small leg) of that triangle would be the apothem
The hypotenuse of that triangle would be the radius.
I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

What are the coordinates of the focus of the parabola? (x+1)2=−8(y−2) (−1, 2) (1, −2) (−1, 0) (−1, 1)
Answer:
[tex](x,y) = (-1,0)[/tex]
Step-by-step explanation:
Given
[tex](x+1)^2 = -8(y-2)[/tex]
Required
The coordinates of the focus
First, write the expression in form of: [tex]y=a(x-h)^2+k[/tex]
[tex](x+1)^2 = -8(y-2)[/tex]
[tex](x+1)^2 = -8y + 16[/tex]
[tex]-8y + 16 = (x+1)^2[/tex]
Subtract 16 from both sides
[tex]-8y = (x+1)^2 - 16[/tex]
Divide through by -8
[tex]y = -\frac{1}{8}(x+1)^2 - \frac{16}{-8}[/tex]
[tex]y = -\frac{1}{8}(x+1)^2 +2[/tex]
In this case:
[tex]a = -\frac{1}{8}[/tex]
[tex]-h = 1[/tex] [tex]h = -1[/tex]
[tex]k = 2[/tex]
The focus of the parabola is:
[tex](x,y) = (h,k + \frac{1}{4a})[/tex]
This gives:
[tex](x,y) = (-1,2 + \frac{1}{4*-\frac{1}{8}})[/tex]
[tex](x,y) = (-1,2 + \frac{1}{-\frac{1}{2}})[/tex]
[tex](x,y) = (-1,2 -2)[/tex]
[tex](x,y) = (-1,0)[/tex]

18 is 14 percent of what?
Answer:
18 is 14% of 128.5714
Step-by-step explanation:
it's 77.78
Step-by-step explanation:
14: 18*100 =
(14*100): 18 =
1400: 18 = 77.78
Now we have: 14 is what percent of 18 = 77.78
Question: 14 is what percent of 18?
Percentage solution with steps:
Step 1: We make the assumption that 18 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=18$100%=18.
Step 4: In the same vein, $x\%=14$x%=14.
Step 5: This gives us a pair of simple equations:
$100\%=18(1)$100%=18(1).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{18}{14}$100%x%=1814
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{14}{18}$x%100%=1418
$\Rightarrow x=77.78\%$⇒x=77.78%
Therefore, $14$14 is $77.78\%$77.78% of $18$18.

1/3x-8= -12
A. x= -12
B. x= -6
C. x= 4

Answer:
A
Step-by-step explanation:
Given

x - 24 = - 36 ( add 24 to both sides )
x = - 12 → A
A vet borrows $12,000 for 4 years. The total interest paid was $960. What was the interest rate on the loan?
Answer:
2% per year.
Step-by-step explanation:
Solving our equation
r = 960 / ( 12000 × 4 ) = 0.02
r = 0.02
converting r decimal to a percentage
R = 0.02 * 100 = 2%/year
The interest rate required to
accumulate simple interest of $ 960.00
from a principal of $ 12,000.00
over 4 years is 2% per year.
A population of rabbits in a lab, p(x), can be modeled by the function p(x)=20(1.014)^x, where x represents the number of days since the population was first counted.
Answer:
(a) 20 represents the initial population and
1.014 represents 1 + % growth of rabbits each day
(b) Average Rate of change = 0.8
Step-by-step explanation:
P.S - The exact question is -
Given - A population of rabbits in a lab, p(x), can be modeled by
the function p(x)=20(1.014)^x, where x represents the number
of days since the population was first counted.
To find - (a) Explain what 20 and 1.014 represent in the context of
the problem.
(b) Determine, to the nearest tenth, the average rate of
change from day 50 to day 100.
Proof -
(a)
Given that the function p(x) is represented as
[tex]p(x) = 20(1.014)^{x}[/tex]
Here,
20 represents the initial population and
1.014 represents 1 + % growth of rabbits each day
(b)
Given,
[tex]p(x) = 20(1.014)^{x}[/tex]
When x = 50
[tex]p(50) = 20(1.014)^{50}[/tex] = 40.08000 ≈ 40.1
When x = 100
[tex]p(100) = 20(1.014)^{100}[/tex] = 80.32033 ≈ 80.3
Now,
Average Rate of change = [tex]\frac{p(100) - p(50)}{100 - 50}[/tex]
= [tex]\frac{80.3 - 40.1}{50}[/tex]
= [tex]\frac{40.2}{50}[/tex]
= 0.804 ≈ 0.8
⇒Average Rate of change = 0.8

Step-by-step explanation:

a) what is the chance of pulling out an A and then a Z in two consecutive turns?
b) starting again, what is the chance of pulling out two vowels in two consecutive turns?
Answer:
A: 3.84% chance.
B: 23.08% chance
The chance of pulling out an A and then a Z and two vowels in two consecutive turns will be 1 / 650 and 2 / 65, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
The letters of the alphabet are written on pieces of paper and put into a hat. they are then pulled out and not replaced.
Then the total number of letters of the alphabet will be 26.
Then the chance of pulling out an A and then a Z in two consecutive turns will be given as,
P = (1 / 26) x (1 / 25)
P = 1/650
The chance of pulling out two vowels in two consecutive turns will be given as,
P = (5 / 26) x (4 / 25)
P = 20 / 650
P = 2 / 65
The chance of pulling out an A and then a Z and two vowels in two consecutive turns will be 1 / 650 and 2 / 65, respectively.

Step-by-step explanation:
1/2x - 7 = 1/3 (x- 12)
Answer:
x = 18
Step-by-step explanation:
1/2x - 7 = 1/3 (x- 12)
Multiply both sides by 3
3 * 1/2x - 3 * 7 = 3 * 1/3 (x - 12)
3/2x - 21 = x - 12
Collect like terms
3/2x - x = 21 - 12
1/2x = 9
Multiply both sides by 2
x = 2 * 9
x = 18
Answer:
x = 18
