If you mean 40% of the circle with the rotation at the center of the circle, then you do this:
Measure of circle: 360°
Amount of circle's measure: 40%
360 * 40% = 144°

Thus, to take up 40% of the circle you need to have an angle measure of 144°.

Part 1: What mistake did AJ make in the graph?
grigory [225]

Answer:

Part 1) AJ drawn the parabola opening upwards, instead of drawing it opening downwards

Part 2) see the explanation

Step-by-step explanation:

Part 1) What mistake did AJ make in the graph?

we have

f(x)=-(x+2)^2-1

This is the equation of a vertical parabola written in vertex form

The parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

The vertex is the point (-2,-1)

therefore

AJ drawn the parabola opening upwards, instead of drawing it opening downwards

Part 2) Evaluate any two x-values (between -5 and 5) into AJ's function. Show your work. How does your work prove that AJ made a mistake in the graph?

take the values x=-4 and x=4

For x=-4

substitute the value of x in the quadratic equation

f(x)=-(-4+2)^2-1\\f(x)=-5

For x=4

substitute the value of x in the quadratic equation

f(x)=-(4+2)^2-1\\f(x)=-37

According to AJ's graph for the value of x=-4 the function should be positive, however it is negative and for the value of x=4 the function should be positive and the function is negative

therefore

AJ made a mistake in the graph

Given the function, f(x)=x^2-3 , calculate the average rate of change of the function from x=1 to x=3
viktelen [127]
Rate of change(m) = (f(3) - f(1))/(3-1)

m = (6 - -2)/(3-1)
m = 8/2
m = 4

Suzy randomly picks marbles form a bag containing 13 identical marbles. how many possible outcomes are there of she selects 10 m
allsm [11]

Answer:

 286 possible outcomes.

Step-by-step explanation:

We have been given total 13 identical marbles

We need to select 10 out of 13

We will use combination:

^nC_r=\frac{n!}{r!(n-r)!}

here,n=13 and r=10 on substituting the values in the formula we get:

^13C_{10}=\frac{13!}{10!(13-10)!}

^13C_{10}=\frac{13\cdot 12\cdot 11\cdot10!}{10!\cdot 3!}

\Rightarrow ^13C_{10}=\frac{13\cdot12\cdot11}{3\cdot2\cdot1}

\Rightarrow 286

So, there are 286 possible outcomes.
