Answer:
f(x) + g(x) is 2(2x² - 4x - 3)
Step-by-step explanation:
[tex]f(x) + g(x) = (x)(2x + 5) + ( {2x}^{2} - 13x + 6) \\ = (2 {x}^{2} + 5x) + (2 {x}^{2} - 13x + 6) \\ = 4 {x}^{2} - 8x - 6 \\ = 2(2 {x}^{2} - 4x - 3)[/tex]

Padma cycled p km on Monday. She cycled 8 km less on Tuesday. What was the distance she cycled on Tuesday?
Distance cycled on Monday = p km
Distance cycled of Tuesday
= 8 km less than the distance cycled on Monday
= p km - 8 km
= (p - 8) km
So, distance cycled of Tuesday is (p - 8) km.

You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 3.2 feet long, if the remaining piece needs to be 0.66 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth.
Answer:
11.2
Step-by-step explanation:
3.2 / 0.66 = 4.8484...
3.2 + 3.2 + 4.8484... = 11.24848...

7. GEOMETRY The radius r of a certain
circle is given by r = V71. Estimate the
radius of the circle to the nearest foot.
Please help
Numbers can be estimated by approximating them. So, we need to approximate [tex]\sqrt{71}[/tex] to the nearest integer to get its estimate of the radius in the nearest foot.
The radius to the nearest foot is 8ft
Given that
[tex]r = \sqrt{71}[/tex]
To calculate the radius, we simply determine the square root of 71
[tex]r = 8.42614977318[/tex]
Approximate to the nearest integer
[tex]r = 8[/tex]
Hence, the radius of the circle to the nearest foot is 8ft.

Match the given arc or inscribed angle to its measure.
1. x = 38°
2. x = 180°
3. x = 104°
4. x = 84°
Answer:
x = 38 is for problem A
x = 180 is for problem C
x = 84 is for problem D
x = 104 is for problem B
Step-by-step explanation:
If I explained something in a complicated way and you want to learn how to do it well let me know and I can give you resources to learn it and master it or even rephrase what you misunderstood.Explanation for problem A: An angle that has endpoints at the endpoints of an arc is equal to half that arcs angle. (example: in problem A the arc measure is 76 meaning that angle x is equal to half of 76 which is 38. you can also see angle x ends at D and C which are the endpoint of the arc as well) This form of thinking using the rule I mentioned in the first sentence is used to solve each of the problems. Also if the arc measure isn't given and you must solve for it do the opposite; times the angle that has the same endpoints as the arc by 2 (example: In problem B angle ∠S has endpoints of Q and R which are also the endpoints of the arc you're looking for (Arc QR) so since an angle that has the same endpoints as an arc is equal to half that arcs measure, in order to get the arc measure you must times the angle by 2.)

What are Sets?Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.
In a group of 150 people, 120 like to play volleyball and 85 like to play football. If 25 like to play up of the games.
The number of people who play volleyball and/or football is calculated as,
A∪B = 150 - 25
A∪B = 125
The number of people who play both volleyball and football is calculated as,
A∩B = A + B - A∪B
A∩B = 120 + 85 - 125
A∩B = 80
The number of people who play both volleyball and football will be 80.

PLEASE HELP ASAP! NO SCAMS!
Answer:
Step-by-step explanation:
Perpendicular means that the slopes of the "old" line and the "new" line are opposite reciprocals; bisector means that the "new" line goes directly through the center of the "old" line. This perpendicular bisector, then, will go directly through the center of the "old" line, cutting it directly in half and leaving in its wake a 90 degree angle. To write this equation, then, of the perpendicular bisector, we need the slope of the old line and the midpoint of the old line. Let's work on the midpoint first:
[tex]M=(\frac{3+6}{2},\frac{5-7}{2})\\M=(\frac{9}{2},\frac{-2}{2})\\M=(\frac{9}{2},-1)[/tex] So the "new" line will go through this point.
Onto the slope:
[tex]m=\frac{-7-5}{6-3}\\m=\frac{-12}{3}[/tex]so the slope is
m = -4. That means that the perpendicular slope is
[tex]m=\frac{1}{4}[/tex] Now we're ready to write the equation:
[tex]y-5=\frac{1}{4}(x-3)[/tex] and
[tex]y-5=\frac{1}{4}x-\frac{3}{4}\\y=\frac{1}{4}x-\frac{3}{4}+\frac{20}{4}[/tex] and finally,
[tex]y=\frac{1}{4}x+\frac{17}{4}[/tex]
Answer:
Step-by-step explanation:
A(3, 5) ; B(6,-7)
Let's find the slope of AB = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]=\dfrac{-7-5}{6-3}\\\\=\dfrac{-12}{3}\\\\= - 4[/tex]
m = -4
Slope of the perpendicular line to AB = -1/m = [tex]\dfrac{-1}{-4}=\dfrac{1}{4}[/tex]
The perpendicular line of AB is bisector also. So, it goes through the midpoint of AB
Midpoint of AB = [tex](\dfrac{x_{1}+x_{2}}{2}, \dfrac{y_{2}-y_{1}}{2})[/tex]
[tex]=(\dfrac{3+6}{2},\dfrac{5+(-7)}{2})\\\\=(\dfrac{9}{2},\dfrac{-2}{2})\\\\=(\dfrac{9}{2},-1)[/tex]
Equation of require perpendicular line: y - y1 = m (x -x1)
[tex](x_{1},y_{1})= (\dfrac{9}{2},-1)\\ \\m =\dfrac{1}{4}\\\\y-[-1]=\dfrac{1}{4}(x-\dfrac{9}{2})\\\\y+1=\dfrac{1}{4}x-\dfrac{1}{4}*\dfrac{9}{2}\\\\y=\dfrac{1}{4}x-\dfrac{9}{8}-1\\\\y=\dfrac{1}{4}x-\dfrac{9}{8}-\dfrac{8}{8}\\\\y=\dfrac{1}{4}x-\dfrac{17}{8}[/tex]
Brody works part-time at a veterinarian's office in addition to going to college, and he is paid twice a month. Which type of budget would likely work best for Brody?
The type of budget that would likely work best for Brody is biweeky budget.
Budget is an economic term that refers to the planning and advance formulation of expenses and income. The budget is a tool to organize expenses depending on the amount of money available.
The type of budget that would be best for Brody is a biweekly budget because he receives his payment every fifteen days (twice a month). So, he can schedule his expenses each time he receives his payment, in this way he does not spend all his money before he receives the next payment.
Additionally, weekly, monthly, and dairy are not correct options because they do not fit the time periods in which Brody receives payment for his services.

Which of the following could be the value of xy if y = 7and x>7?
Answer:
Any number greater than 49.
Step-by-step explanation:
Since 7>0 then multiplying both sides of x>7 by 7 will not effect the direction of the inequality.
If x>7, then 7x>7(7) or 7x>49 after simplifying.
Substituting y for 7 since y=7 gives yx>49.
By commutative property of multiplication we have xy>49.
So any number greater than 49.

if you have a cylindrical tank that's 10 feet long and has a radius of 2 feet, what's the maximum possible capacity of the tank in gallons of water if 1 cubic foot of water = 7.48 gallons? Round your answer to two decimal places.
Answer:
Step-by-step explanation:
Volume = pi * r^2 * h
r = 2 feet
h = 10 feet
Volume = 3.14 * 2^2 * 10
Volume = 125.6 cubic feet
1 cubic foot contains 7.48 gallons
125.6 cubic feet contain 7.48 * 125.6 = 930.488
The tank contains 930.49 gallons.

The translation of ABCD to A'B'C'D'
is given by (×+[?].y-[ ]).
Answer:
(x + 1 , y - 3)
Step-by-step explanation:
Compare x-coordinate of A(-6,1) and A'(-5,-2)
-6 + a = -5
a = -5 +6 = 1
x- coordinate of A' = x coordinate of A + 1
Compare y-coordinate of A(-6,1) and A'(-5,-2)
1 + a =-2
a = -2 - 1 = -3
y- coordinate of A' = y coordinate of A - 3
A(-6 , 1) = A'(-6+1 , 1-3) = A'(-5, -2)
D(( -1 , 1) = D'(-1+1, 1 - 3) = D'(0,-2)
