The values of a continuous function f are given which are false is  By the Mean Value Theorem applied to f on the interval (2,5), there is a value c such that f' (c) = 10. So, the correct option is statement (B). Let f be the function defined by f (x) = r - 6x2 + 9x + 4 for 0 < 3 < 3 then f is decreasing on the interval (1,3) because f' (2) < 0 on the interval (1, 3). So, the correct option is D).

For continuous function f the statement (B) is false. Although the Mean Value Theorem guarantees the existence of a point c such that f'(c) = (f(5)-f(2))/(5-2) = 2, there is no guarantee that this value will be exactly 10.

When f (x) = r - 6x2 + 9x + 4 for 0 < 3 < 3 is statement (D) is true. We have f'(x) = -12x + 9, which is negative for x in the interval (1,3). Therefore, f is decreasing on this interval. Statement (A) is false, as f'(2) = 3 is positive, so f is increasing on the interval (0,1).

Statement (B) is also false, as f'(x) is not negative on the interval (0,1). Statement (C) is false, as f" (x) = -12 is negative everywhere, so f is concave down on the entire interval (0,3).

Answer:

46.8 cm²

Step-by-step explanation:

The diagonal of the square has length \(\sqrt{6^2+10^2}=2\sqrt{34}\). Therefore, the radius of the circle is \(\sqrt{34}\), meaning the area is \(\pi(\sqrt{34})^2 \approx 34(3.14)=106.76\).

The area of the rectangle is \((6)(10)=60\) cm².

Subtracting the areas, the answer is 46.76 cm², which is 46.8 cm² to the nearest tenth.

The sum of the digits is 13.

The first digit is 2

The last digit is 0 or 5

Can it be zero?

2 + _ + 0  = 13

2 + 0  _ x = 13                  Subtract 2 from both sides

2 - 2 + 0 + x = 13 - 2        Combine

x = 11

No there is no such thing as a digit is value is 11. So the last digit is 5

2 + __ + 5 = 13

7 + x = 13                          Subtract 7 from both sides

7-7 + x = 13 - 7                 Combine

x = 6

Answer:

y=1.25x+10

Step-by-step explanation:

you can put this into the formula “y=mx+b”. y is the final amount, x is how many times joana gets food or goes on a ride. You can plug into the equation the two parts we know. We know that no matter what, if she goes into the fair, she is going to spend $10 on the admission, even if she does not go on any rides or gets any food. So we put 10 where the “b” is. Then each time she gets food or goes on a ride, she pays another $1.25. Therefore, you can plug 1.25 into where the m is. That leaves you with “y=1.25x+10”.

Answer:

8 footballs

18 basketballs

36 baseballs

24 softballs

Step-by-step explanation:

Let f = footballs

f = 8

Let b = basketballs

b = 2+2f = 2 +2(8) = 2 +16 = 18

Let B = baseballs

B = 5f -4 = 5(8) -4 = 40-4 = 36

Let s = softballs

s = 6+1/2B = 6+1/2(36) = 6+18 = 24

The total is 86

f+b+B +s = 86

8+18+36+24 = 86

86=86

There are 8 footballs.

Two more than twice the number of footballs are basketballs:

2f + 2 = b

f = number of footballs

b = number of basketballs

In the first statement, there are 8 footballs. So, f = 8

2(8) + 2 = b

16 + 2 = b

18 = b

Therefore, there are 18 basketballs.

Four less than 5 times the number of footballs are baseballs:

5f - 4 = a

f = number of footballs

a = number of baseballs

In the first statement, there are 8 footballs. So, f = 8

5(8) - 4 = a

40 - 4 = a

36 = a

Therefore, there are 36 baseballs.

Six more than half of the baseballs are softballs:

a/2 + 6 = s

a = number of baseballs

s = number of softballs

In the third statement, there are 36 baseballs. So, a = 36

(36)/2 + 6 = s

18 + 6 = s

24 = s

Therefore, there are 24 softballs.

Answer:

120.

Step-by-step explanation:

Para poder determinar el numero de canicas que Juan tiene, se debe obtener el múltiplo común mayor entre 2, 3 y 5, que sea menor a 200. Así, para ser múltiplo de 2 debe ser un número par, para ser múltiplo de 3 sus dígitos deben sumar un número divisible por 3, y para ser múltiplo de 5 debe terminar en 5 o 0.

Así, dado que 0 es par, se debe tratar de un número terminado en 0, divisible por 3: puede tratarse de los números 120, 150 o 180. Así, dado que 119/7 es igual a 17, sobrando 1 para completar el número 120, el número de canicas que Juan tiene es 120.

Step-by-step explanation:

The measure of the complement of a 1-degree angle is 89 degrees.

The complement of an angle is defined as the angle that, when added to the given angle, results in a sum of 90 degrees. To find the measure of the complement of a 1-degree angle, we need to determine the angle that, when added to 1 degree, equals 90 degrees.

Let's denote the measure of the complement as x degrees. According to the definition, we can set up the equation:

1 degree + x degrees = 90 degrees.

To solve for x, we need to isolate it on one side of the equation. By subtracting 1 degree from both sides, we have:

x degrees = 90 degrees - 1 degree.

Simplifying the right side, we get:

x degrees = 89 degrees.

In summary, when an angle measures 1 degree, its complement measures 89 degrees. Complementary angles are pairs of angles that add up to 90 degrees. In this case, since the given angle measures only 1 degree, its complement is significantly larger, nearly forming a right angle. The concept of complementary angles is fundamental in geometry and can be applied to various problems involving angles and their relationships.

Answer:

  f(n) = -n^2 -3n +5

Step-by-step explanation:

Suppose the formula is ...

  f(n) = an^2 +bn +c

Then we have ...

  f(1) = 1 = a(1^2) +b(1) +c

  f(2) = -5 = a(2^2) +b(2) +c

  f(3) = -13 = a(3^2) +b(3) +c

__

Here's a way to solve these equations.

Subtract the first equation from the second:

  -6 = 3a +b . . . . . 4th equation

Subtract the second equation from the third:

  -8 = 5a +b . . . . . 5th equation

Subtract the fourth equation from the fifth:

  -2 = 2a

  a = -1

Then substituting into the 4th equation to find b, we have ...

  -6 = 3(-1) +b

  -3 = b

and ...

  1 = -1 +(-3) +c . . . . . substituting "a" and "b" into the first equation

  5 = c

The formula is ...

  f(n) = -n^2 -3n +5

The numbers 2, 10, 10, 14, and 16 made up the population. The standard deviation for the population is 4.38.

Ungrouped data is a distribution type where each piece of information is presented in its rawest form. It is shown as individual points (i.e., values or numbers). For instance, a batsman's scores during his previous five matches are 56, 67, 2, 77, and 80. Here the given values are ungrouped data.

First, find the mean from the given data,

\(\begin{aligned}\text{mean}&=2+10+10+14+14\\&=\frac{50}{5}\\&=10\end{aligned}\)

Then subtract this mean from the given data and square the result, and we get a variance from this,

\(\begin{aligned}\text{Variance}&=\frac{\sum (\mu-x)^2}{N}\\&=\frac{(-8)^2+0^2+0^2+4^2+4^2}{5}\\&=\frac{96}{5}\\&=19.2\end{aligned}\)

The square root of variance will help to find the standard deviation,

\(\begin{aligned}SD&=\sqrt{19.2}\\&=4.38\end{aligned}\)

Therefore, the required answer is 4.38.
