question 1: Multiply and simplify.

x^2⋅x⋅x^5
(I got x^8 but I was unsure.)

question 2: Multiply and simplify.

(3x+7)8x^2

The question is incomplete. Here is the complete question.

Part A

The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.

Express the toy's value t, in dollars, as a function of time w in weeks after purchase.

Part B

Write an expression to represent the toy's value 10 days after purchase

Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]

Part A

Translating to the question, the toy's value as a function of time is

[tex]t=ab^{w}[/tex]

To determine constants a and b, we use points given by graph.

First, (0,5) to find a:

[tex]5=a.b^{0}[/tex]

a = 5

Now, (3,10) to determine b:

[tex]10=5b^{3}[/tex]

[tex]b=\sqrt[3]{2}[/tex]

b = 1.26

The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]

Part B

Since, the function is in weeks:

1 week = 7 days

w weeks = 10 days

[tex]w = \frac{10}{7}[/tex]

Replacing w:

[tex]t=5.(1.26)^{w}[/tex]

[tex]t=5.(1.26)^{10/7}[/tex]

Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].

Step-by-step explanation:

Answer:

116 deg

Step-by-step explanation:

note that an isoceles triangle always have 2 base angles that are equal.

Here we are already given one base angle of 32 deg. It follows that the other base angle must also be 32 deg.

We now have 2 angles of a triangle and we need to find the remaining one. Also recall that all 3 internal angles of a triangle sum to 180 deg. if we let the missing angle be x, then:

base angle + base angle + vertex angle = 180°

or,

32° + 32° + x° = 180°

64° + x = 180 deg

x = 180 - 64

x = 116 deg

Answer:

Step-by-step explanation:

(1, 72) (2, 73)

(73 - 72)/(2 - 1)= 1/1= 1

y - 72 = x - 1

y = x + 71

Answer:

( x - 3) (x + 3)
