State what method you would use to solve the equation. Justify your answer. You do not need to solve the equation.
Answer:
By factoring
Step-by-step explanation:
4x^2+25=20x then:
4x^2-20x+25=0
factoring:
(2x-5)(2x-5)=0
2x=5, x=2.5
4(x + 4y) + 3(4x + y)
Determine en donde la funcion dada es creciente,concava hacia riba y concava hacia abajo. y= x3–3x–1
Answer:
Es creciente en los siguientes intervalos: [tex][-\infty,-1] U [1,\infty][/tex]
Es concavo hacia abajo en el intervalo: [tex][-\infty,0)[/tex]
Es concavo hacia arriba en el intervalo: [tex](0,\infty][/tex]
Step-by-step explanation:
Sea la función:
[tex]f(x)=x^{3}-3x-1[/tex]
Para determinar el intervalo de crecimeinto debes determinar la primer derivada de la función (f'(x)). El intervalo donde f'(x) > 0 es creciente.
La derivada de f(x) es:
[tex]f'(x)=3x^{2}-3[/tex]
Entonces es creciente en los siguientes intervalos:
[tex][-\infty,-1] U [1,\infty][/tex]
Ahora para determinar la concavidad debemos determinar la segunda derivada de la función (f''(x)). Si f''(x) > 0 la función es concava hacia arriba, si f''(x) < 0 la funcion es concava hacia abajo.
La segunda derivada de f(x) es:
[tex]f''(x)=6x[/tex]
Por lo tanto:
Es concavo hacia abajo en el intervalo: [tex][-\infty,0)[/tex]
Es concavo hacia arriba en el intervalo: [tex](0,\infty][/tex]

Step-by-step explanation:
for you to find the missing length of the hypotenuse you need to get your other 2 sides and multiply them by themselves/ square. After that you want to add them together. Now you have to find the square root of that total number which will be your length.

There are 8 times as many dogs as cats. If the total number of dogs and cats is 45, how many dogs are there?
Answer:
40
Step-by-step explanation:
because if there are 5 cats and then there are 8 TIMES AS CATS then its 8 * 5= 40 +5 = 45
WHY 45?
because the total of cats and dogs is 45

1 s = 3 m
2 s = 6 m
42/3 = 14
14 s = 42 m
16 X 3 = 48
16 s = 48 m
72/3 = 24
24 s = 72 m
m = s X 3
s= m/3

Shawn owns The Muffin mobile food truck. He goes home after he sells more than 200 muffins. He began the day with a big 36 muffin order! Now he's selling 24 muffins per hour. After how many complete hours can Shawn go home?
Answer:
Step-by-step explanation:
he sold 36 so lets subtract that from the 200 so he has to sell 164 more.
Now we have to figure out what times 24 is 164
It is about 7 because 24 x 7 = 28 and if he needs to sell mORE THAN it can't be 6 so it is 7 hours.

The population of a small town is 6800 in 2013. The population increases by 6% annually. What was the population in 2020?
Answer:47 600 in 2020
Explanation:Mutiply 6,800 and 7 because 2013 subtract 2020 the answer is 7, the answer in 6,800 and 7 is 47 600 , dapat kapag dinivide mo sa 6% ang 47 600 ang sagot ay 6,800 dahil yun ang population kada years

Step-by-step explanation:
There are some chickens and pigs in a farm. If you count the number of heads, you get 80 heads. If you count the number of feet, you get 254 feet. How many chickens and how many pigs are there?
Step-by-step explanation:
Let's assume that x = number of chickens and y = number of pigs.
[tex]80 \: heads = x + y[/tex]
Since there are 4 feet for pigs and 2 feet for chickens:
[tex]254 \: feet = 2x + 4y[/tex]
By substitution, let's rearrange the first equation:
[tex]x = 80 - y[/tex]
Substituting this equation to the second one:
[tex]254 = 2(80 - y) + 4y \\ 254 = 160 - 2y + 4y \\ 254 - 160 = 2y \\ 94 = 2y \\ y = 47 \: pigs[/tex]
Since we found the number of pigs already, let's substitute the value to any of the equations.
[tex]80 = x + y \\ 80 = x + 47 \\ 80 - 47= x \\ x = 33 \: chickens[/tex]
There are 32 chickens and 48 pigs.
To check if 3e are correct, let's use the second equation:
[tex]254 = 2x + 4y \\ 254 = 2(33) + 4(47) \\ 254 = 66 + 188 \\ 254 = 254[/tex]
Therefore, the values we found are correct.

Find the area of the isosceles trapezoid below by using the area formulas for rectangles and triangles. A = 10 cm, b = 14 cm, and c = 5 cm
Answer:
The area is 60 cm^2
Step-by-step explanation:
Here, we want to calculate the area of the isosceles trapezoid
Mathematically, the area is ;
Area = 1/2( a + b) c
Thus, we have that;
Area = 1/2(10 + 14)5
= 1/2 * 24 * 5
= 60 cm^2

Find the midpoint of the segment.
A. (4, 2)
B. (1, 0)
C. (-4, 0)
D. (0, 1)
Answer:
B. (1, 0)
Step-by-step explanation:
9514 1404 393
Answer:
B. (1, 0)
Step-by-step explanation:
You can count grid squares on the graph to find the point that is 4 of the 8 units horizontally between the points, and 2 of the 4 units vertically between the points. That will be ...
C +(4, 2) = D -(4, 2) = (1, 0)
__
Or, you can use the midpoint formula:
M = (C +D)/2
M = ((-3, -2) +(5, 2))/2 = (-3+5, -2+2)/2 = (2, 0)/2
M = (1, 0)
The midpoint is (1, 0).
