Answer:

  • A. The value of the baseball card would be $27.24 in 2022.

Step-by-step explanation:

<u>Function:</u>

  • y = 5.89 + 0.61x

<u>Let's verify the answer options:</u>

A. The value of the baseball card would be $27.24 in 2022.

  • y = 5.89 + 0.61*(2022-1987)
  • y = 27.24
  • Correct

B. The value of the baseball card would be $36.52 in 2017.

  • y = 5.89 + 0.61(2017 - 1987)
  • y = 24.19
  • Incorrect

C. The value of the baseball card would be $21.35 in 2022.

  • y = 5.89 + 0.61(2022 - 1987)
  • y = 27.24
  • Incorrect

D. The value of the baseball card would be $18.30 in 2017.

  • y = 5.89 + 0.61(2017 - 1987)
  • y = 24.19
  • Incorrect

Let f be a differentiable function such that f(0) = -5 and f'(x) is less than or equal to 3 for all x. Of the following, which i
stepladder [879]
E) 2 
 Remember that the first derivative of a function is the slope of the function at any specified point. We've been told that f(0) = -5 and that f'(x) is always less than or equal to 3. So let's look at the available options and see what the average slope would have to be in order to get the specified value of f(2).
 A) -10: (-10 - -5)/(2 - 0) = -5/2 = -2.5
 B) -5: (-5 - -5)/(2 - 0) = 0/2 = 0
 C) 0: (0 - -5)/(2 - 0) = 5/2 = 2.5
 D) 1: (1 - -5)/(2 - 0) = 6/2 = 3
 E) 2: (2 - -5)/(2 - 0) = 7/2 = 3.5 
 Now taking into consideration the mean value theorem, the value of the function f'(x) has to have the value equal to the average slope between the two points at at least one point between the two given values. For options A, B, C, and D it's possible for f'(x) to return values that make that slope possible. However, for option E, the mean value theorem indicates that f'(x) has to have the value of 3.5 for at least 1 point between x=0 and x=2. And since we've been told that f'(x) is less than or equal to 3 for all possible values of x, that is in conflict and f(2) can not have the value of 2.

Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image
saw5 [17]
Hello!

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

\frac{hb}{2}

h is height
b is base

Put in the values you know
\frac{7 * 14}{2}

Multiply

\frac{98}{2} = 49

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Hope this helps!

Can someone help me with this question I'll give brainliest answer to whoever helps.

Answer: B) It represents the product of two irrational numbers and is equivalent to an irrational number.


Step-by-step explanation:

1. By a definition an irrational number cannot be written as a simple fraction.

2. Keeping this information on mind:

\sqrt{3}=1.73 (Cannot be written as a simple fraction. It is an irrational number).

\sqrt{2}=1.41 (Cannot be written as a simple fraction. It is an irrational number).

3. When you multiply this irrational number, you obtain:

\sqrt{3}*\sqrt{2}=\sqrt{6}

4. \sqrt{6}=2.44 is an irrational number.

5. Therefore, the answer is the option B,
