Answer: 20%

Step-by-step explanation:

Given : The expected weight of new born lion = 2.8 pounds

The actual weight of new born lion = 3.5 pounds

The formula to find the percent error is given by :-

\text{Percent error}=\dfrac{|\text{Expected value-Actual value}|}{\text{Actual value}}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{|2.8-3.5|}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{0.7}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=20\%

Therefore, the zookeeper’s percent error = 20 %

What is the average rate of change of the function from x = 0 to x = 2?.
irina1246 [14]

The average rate of change of the function from x = 0 to x = 2 is -2

From the complete question (see attachment), we have the following ordered pair when x = 0 and x = 2

(x,y) = \{(0,10)\ (2,6)\}

The average rate of change is calculated using:

\Delta x = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

\Delta x = \frac{6-10}{2-0}

Evaluate common terms

\Delta x = \frac{-4}{2}

Divide -4 by 2

\Delta x = -2

Hence, the average rate of change of the function from x = 0 to x = 2 is -2

Adjacent i need help understanding this
Cerrena [4.2K]

Answer:

The definition of adjacent in math can mean a couple of different things. For angles, adjacent angles would be any two angles that share a side. In other words, two angles right next to each other.

A more broad meaning is just any two geometric shapes that are next to each other in a figure.

Please help very urgent on test...
stepladder [879]

Answer:

Equation: (2x+5)4=(2x+8)3

X: 2

Perimeter: 36

Step-by-step explanation:

You would multiply 2x+5 and 4 because there are four sides to a square, so the perimeter of the square would be 8x+20. This would go same for the triangle, making the perimeter 6x+24.

So 8x+20=6x+24 is your new equation. Then, you do the opposite of the order of operations, and add or subtract first. It would be easiest to subtract 20 and 6x from both sides.

That leaves you with 2x=4. Dividing 2 by both sides means x=2

You can plug this in to prove if it is correct.

16+20=36

12+24=36

Lmk if you get it!
