<h3>Answer:  362.5 inches</h3>

Explanation:

The scale 1:25 means "multiply by 25" in order to go from the scale model length to the actual length in reality.

If your model is 14.5 inches tall, then the actual height is 14.5*25 = 362.5 inches.

Side note: 362.5 inches = 362.5/12 = 30.20833 feet approximately

John spent $75 on a shopping trip for new clothes last week. He had expected to spend $100 on clothes. table How much was the ab
kolezko [41]

Answer:

\$\ 25

Step-by-step explanation:

By definition, the absolute error is defined as:

\epsilon = |x_a - x_e|

Where:

\epsilon: is the error

x_a: is the approximate value

x_e: is the exact value

In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

\epsilon = |100 - 75|\\\epsilon = \$\ 25

Find f such that the given conditions are satisfiedf’(x)=x-4, f(2)=-1
kicyunya [14]

Given:

f^{\prime}\left(x\right)=x-4,\text{ and}f\left(2\right)=-1

To find:

The correct function.

Explanation:

Let us consider the function given in option D.

f(x)=\frac{x^2}{2}-4x+5

Differentiating with respect to x we get,

\begin{gathered} f^{\prime}(x)=\frac{2x}{2}-4 \\ f^{\prime}(x)=x-4 \end{gathered}

Substituting x = 2 in the function f(x), we get

\begin{gathered} f(2)=\frac{2^2}{2}-4(2)+5 \\ =2-8+5 \\ =-6+5 \\ f(2)=-1 \end{gathered}

Therefore, the given conditions are satisfied.

So, the function is,

f(x)=\frac{x^{2}}{2}-4x+5

Final answer: Option D
