No, Amits reasoning is not correct. The problem used to represent the equation, (-5.75) × 7, was solved incorrectly. (-5.75) × 7 = (-40.25). We know this because a negative number times a positive number is always a negative number. So the correct answer for the change in Amits bank account is -40.25

47.

a- Ivan's expression: $4.25 + $1.25(m)

Vicky's expression: $5.75 + $0.75(m)

b- $4.25 + $1.25(m) + $5.75 + $0.75(m)

[add $4.25 + $5.75]

$10.00 + $1.25(m) + $0.75(m)

[add $1.25(m) + $0.75(m)]

$10.00 + $2.00(m)

c- $10.00 + $2.00(m)

d- $10.00 + $2.00(m)

[2 ÷ 2 = 1]

[10 ÷ 2 = 5]

e- 2(m + 5)

A quadratic function and an exponential function are graphed below. How do the decay rates of the functions compareover the inte

Kobotan [32]

To check the decay rate, we need to check the variation in y-axis.

Since our interval is

$-2We need to evaluate both function at those limits.At x = -2, we have a value of 4 for both of them, at x = 0 we have 1 for the exponential function and 0 to the quadratic function. Let's call the exponential f(x), and the quadratic g(x).[tex]\begin{gathered} f(-2)=g(-2)=4 \\ f(0)=1 \\ g(0)=0 \end{gathered}$

To compare the decay rates we need to check the variation on the y-axis of both functions.

$\begin{gathered} \Delta y_1=f(-2)-f(0)=4-1=3 \\ \Delta y_2=g(-2)-g(0)=4-0=4 \end{gathered}$

Now, we calculate their ratio to find how they compare:

$\frac{\Delta y_1}{\Delta y_2}=\frac{3}{4}$

This tell us that the exponential function decays at three-fourths the rate of the quadratic function.

And this is the fourth option.

Below is the graph of f ′(x), the derivative of f(x), and has x-intercepts at x = –3, x = 1 and x = 2. There are horizontal tang

mojhsa [17]

Answer:

C. f has a relative maximum at x = 1.

Step-by-step explanation:

A. False. f(x) is concave down when f"(x) is negative. f"(x) is the tangent slope of the graph, f'(x). So f(x) is concave down between x = -1.5 and x = 1.5.

B. False. f(x) is decreasing when f'(x) is negative. So f(x) is decreasing in the intervals x < -3 and 1 < x < 2.

C. True. f(x) has a relative maximum where f'(x) = 0 and changes from + to -.
