Answer:
f(x)=(x-5)(x-7)
(x-6)²-1²
Step-by-step explanation:
Given:
Equation:
f(x)=x²-12x+35
Find:
Factories
Vertex form
Computation:
Factories
f(x)=x²-12x+35
f(x)=x²-(5+7)x+35
f(x)=x²-5x-7x+35
f(x)=x(x-5)-7(x-5)
f(x)=(x-5)(x-7)
So,
x = 5 , x = 7
Vertex form
By middle term divide by 2
12/2 = 6
So,
x²-12x+6²+35-6²
(x-6)²-1²
A town has a population of 2000 and grows at 4% every year write an equation to represent the scenario
Answer: [tex]P=2000(1.04)^t[/tex].
Step-by-step explanation:
It is given that,
Initial population of a town = 2000
Growth rate = 4% = 0.04 per year
The exponential growth function for population is
[tex]P=P_0(1+r)^t[/tex]
where, [tex]P_0[/tex] is initial population, r is growth rate and t is number of years.
Substitute [tex]P_0=2000,r=0.04[/tex] in the above equation.
[tex]P=2000(1+0.04)^t[/tex]
[tex]P=2000(1.04)^t[/tex]
Therefore, the required equation is [tex]P=2000(1.04)^t[/tex], where P is population after t years.

Step-by-step explanation:
Paul has $20,000 to invest. His intent is to earn 11% interest on his investment. He can invest part of his money at 8% interest and part at 12% interest. How much does Paul need to invest in each option to make get a total 11% return on his $20,000?
Answer:
In the 8% option , $5,000 should be invested
In the 12% option, $15,000 should be invested
Step-by-step explanation:
Let’s start with the total return.
Since the total return expected is 11%, the amount expected to be returned will be;
11/100 * 20,000 = $2,200
Now, let the amount invested at 8% interest be $x while the amount invested at 12% interest be $y
Mathematically;
x + y = 20,000 ••••••(i)
Now let’s work with the interest part;
On the 8% part, amount of interest expected is 8/100 * x
on the 12% part, amount of interest expected is 12/100 * x
8% of $x + 12% of $y = 2,200
Writing this fully mathematically, we have;
(8/100 * x) + (12/100 * y) = 2,200
8x/100 + 12y/100 = 2,200
Multiply through by 100
8x + 12y = 220,000 ••••••(ii)
Now we have two equations to solve simultaneously;
x + y = 20,000
8x + 12y = 220,000
From i, x = 20,000-y
Substitute this into ii
8(20,000-y) + 12y = 220,000
160,000-8y + 12y = 220,000
4y = 220,000 - 160,000
4y = 60,000
y = 60,000/4
y = $15,000
x = 20,000 -y
x = 20,000 - 15,000
x = $5,000

Hey there! I'm happy to help!
If something is 11 less, we are subtracting 11.
-11
We have 11 less than seven times a number x.
7x-11
The word is means equals.
7x-11=-4
Now we need to isolate the x. We add 11 to both sides.
7x=7
We divide both sides by 7.
x=1.

A patient's temperature was recorded at 9 a.m., 11 a.m., 4 p.m. and 6 p.m. The first, second, and fourth readings were 112° F, 68° F and 85° F, respectively. If the average of the four readings was 84.75° F,
what was the third reading?
Answer:
74°F
Step-by-step explanation:
In order to find the average of a certain amount of numbers, you add those numbers together and divide by how many numbers there are. In this case, you would reverse that method to find the last number. We know that there were four readings, and we have three of them and the average. Multiply the average (84.75) by the number of readings (4), and you get the sum of all the readings (339). Then you subtract each of the readings that you already know to isolate the last reading. 339 - 112 (first reading) = 227, 227 - 68 (second reading) = 159, and 159 - 85 (fourth reading) = 74. Therefore, the third reading must be 74.

6. As part of their employee benefits, all workers at Light and Power Electric Company
receive a pension that is calculated by multiplying the number of years worked
times 1.875% of the average of their three highest years' salaries. Mia has
worked for LPEC for 30 years and is retiring. Her highest salaries were
$92,000, $94,800, and $96,250. Calculate Mia's pension.
Answer:
$1769.06
Step-by-step explanation:
The sum of Mia's three highest salaries is ...
$92,000 +94,800 +96,250 = $283,050
so the average is ...
$283,050/3 = $94,350
Her pension is then ...
0.01875 × $94,350 = $1769.06
_____
Additional comment
This is equivalent to the total of those salaries, divided by 160.
T/3 × 0.01875 = T × (0.01875/3) = T × 0.00625 = T/160
Sometimes, there are simpler ways to calculate things like this.

Answer:
[tex] \boxed{\sf Height \ of \ parallelogram \ (h) = 8.4 \ cm} [/tex]
Given:
Area of parallelogram (A) = 31.5 cm²
Base of parallelogram (b) = 3.75 cm
To Find:
Height of parallelogram (h)
Step-by-step explanation:
Area of parallelogram (A) = Base (b) × Height (h)
31.5 = 3.75 × h
h × 3.75 = 31.5
h = [tex] \sf \dfrac{31.5}{3.75} [/tex]
h = 8.4 cm
The height of the parallelogram is 8.4cm with a base of 3.75cm and an area of 31.5 sq cm.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
The area of a parallelogram is base multiples by height as two triangles form a parallelogram.
Given, The area of the parallelogram is 31.5 sq cm and the base is 3.75 cm.
We know the area of a parallelogram is base×height.
∴ h×3.75 = 31.5.
h = (31.5/3.75) cm.
h = 8.4 cm.

Find the equation of the line that passes through the point (5, -4) and is perpendicular to the line y=1/4x - 2 .
Answer:
The equation of the line is:
[tex]y = -4\,x +16[/tex]
Step-by-step explanation:
A line perpendicular to the given one is going to have a slope equal to the opposite of the reciprocal of 1/4. That is the slope of the new line will be "-4".
Now we write the point-slope form for a line using the info provided of slope -4 and point (5, -4):
[tex]y-y_0=m\,(x-x_0)\\y - (-4) = -4 \,(x-5)\\y+4 = -4\,x +20\\y = -4\,x +16[/tex]
Answer:
y = -4x + 16
Step-by-step explanation:
For questions like this, I would first find the slope of the line that we are trying to find the equation for. To do this, I would use the line y = 1/4x - 2 and find the slope of a line that would be perpendicular to it. Taking the negative reciprocal of the slope of y = 1/4x - 2 will do just that.
By looking at the equation y = 1/4x - 2, we can see that the slope of the line is 1/4. The negative reciprocal of 1/4 would be -4, which would be the slope of the line whose equation we are trying to find.
Since we have a point on the line, and we now have the slope of the line, we can now make an equation for the line in point-slope form:
y + 4 = -4(x - 5)
Now while this is an equation for the line, lets try to get it into slope-intercept form:
y + 4 = -4(x - 5)
Distribute the -4 on the right side of the equation.
y + 4 = -4x + 20
Subtract 4 from both sides.
y = -4x + 16
And now we have the equation of the line in slope-intercept form.
I hope you find my answer helpful.
