Answer:

Not a function

Step-by-step explanation:

x repeats, you have 5 mapped to 1 and 5 mapped to 9 so you have to have a one-to-one relationship with your points if it is a function

Answer:

See Explanation

Step-by-step explanation:

Incomplete question as the function is not given. So, I will give a general solution

Required

Determine the average rate of change from t = 2 to 4

Average rate of change is :

[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]

In this case: a = 2 and b = 4

So, we have:

[tex]Rate = \frac{f(4) - f(2)}{4 - 2}[/tex]

[tex]Rate = \frac{f(4) - f(2)}{2}[/tex]

Assume that the exponential function is:

[tex]f(t) = 3^{-t[/tex]

f(4) and f(2) will be:

[tex]\\ f(4) = 3^{-4} = \frac{1}{81}[/tex]

[tex]f(2) = 3^{-2} = \frac{1}{9}[/tex]

So:

[tex]Rate = \frac{f(4) - f(2)}{2}[/tex]

[tex]Rate = \frac{\frac{1}{81} - \frac{1}{9}}{2}[/tex]

Take LCM

[tex]Rate = \frac{\frac{1 - 9}{81}}{2}[/tex]

[tex]Rate = \frac{-\frac{8}{81}}{2}[/tex]

[tex]Rate = -\frac{8}{81}*\frac{1}{2}[/tex]

[tex]Rate = -\frac{4}{81}[/tex]

So, the average rate of change is a decrease of 4/81

Answer:

$275 a week is better buy

Step-by-step explanation:

there are 7 days in a week so total cost for weekly rate will be $275

total cost for per day offers will be $48*7= $336

Answer:

  a) (-2, 0), (0, 0), (1, 0), (3, 0)

  b) (0, 0)

Step-by-step explanation:

a) The graph crosses the x-axis at x = -2, 0, 1, 3. The corresponding (x, y) coordinates are ...

  (-2, 0), (0, 0), (1, 0), (3, 0) . . . . . x-intercepts

__

b) The graph crosses the y-axis at y = 0. The corresponding (x, y) coordinates are ...

  (0, 0) . . . . . y-intercept

Answer:

y = -3x + 5

Step-by-step explanation:

Find the graph attached

The standard form of calculating the equation of a line is expressed as;

y = mx+c

m is the slope

c is the intercept

Using the coordinate points (0, 5) and (1, 2)

m = 2-5/1-0

m = -3/1

m = -3

Get the intercept

Substitute m = -3 and (0,5) into y = mx+c

5 = -3(0) + c

5 = c

c = 5

Get the required equation

Recall that y = mx+c

Substitute the gotten values

y = -3x + 5

[tex]\tt{} \frac{96}{45} = \frac{b }{20} [/tex]

[tex]\tt{} \frac{32}{15} = \frac{b}{20} [/tex]

[tex]\tt{}32 \times 20 = 15b[/tex]

[tex]\tt{}640 = 15b[/tex]

[tex]\tt{}15b = 640[/tex]

[tex]\tt{}b = \frac{640}{15} [/tex]

[tex]\tt{} b= \frac{128}{3} [/tex]

[tex] \blue{\boxed{\rm Answer + Explain }}[/tex]

[tex] \rm \frac{96}{45} = \frac{b}{20} [/tex]

[tex] \rm (\frac{96}{45} \div \frac{3}{3} ) = \frac{b}{20} [/tex]

[tex] \rm \frac{32}{15} = \frac{b}{20} [/tex]

[tex] \rm 32 \times 20 = 15 \times b [/tex]

[tex] \rm 640 = 15b [/tex]

[tex] \rm \frac{640}{15} = b [/tex]

Answer:

336 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a right triangle

A of rectangle = length × breadth = 24 × 12 = 288 ft²

A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 32 - 24 = 8 ft and h = 12 , then

A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²

composite area = 288 + 48 = 336 ft²

Answer:

{all real numbers}

Step-by-step explanation:

Solve (x + 1 < 5) ∩ (x - 4 > -3).

For the expression

x + 1 < 5

Subtract 1 from both sides

x+1-1 < 5-1

x < 4

For the inequality

x - 4 > -3

Add 4 to both sodes

x-4+4 > -3 + 4

x > -1

Hence the intersection of both is on all real numbers since the value of x is greater than -1.

Answer:

x = 53.7 degrees

Step-by-step explanation:

[tex]tan = \frac{opposite}{adjacent}[/tex]

[tex]tan x = \frac{15}{11}[/tex]

tan x = 1.36

tan-1 of 1.36 = 53.7

Answer:

[tex]x= 15[/tex]

Step-by-step explanation:

Francisca's mistake was that when she had an equation [tex]5 = \frac{1}{3} x[/tex] instead of dividing both sides by  [tex]\frac{1}{3}[/tex]  she substracted  [tex]\frac{1}{3}[/tex]  from both sides. So the correct way would be...

[tex]5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)[/tex]

[tex]15 = x[/tex]

Answer:

(-7, 7)

Step-by-step explanation:

The formula for calculating the coordinate point is expressed as;

M(X, Y) = (ax1+bx2/a+b, ay1+by2/a+b)

X = ax1+bx2/a+b

X = 2(-10)+3(-5)/2+3

X = -20-15/5

X = -35/5

X = -7

Y = ay1+by2/a+b

Y = 2(10)+3(5)/2+3

Y = 20+15/5

Y = 35/5

Y = 7

hence the required coordinate is (-7, 7)
