Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (6, 1280)(6,1280).

Answers

Answer:

[tex]y=20(2)^x[/tex]

Step-by-step explanation:

We want to write an exponential function that goes through the points (0, 20) and (6, 1280).

The standard exponential function is given by:

[tex]y=ab^x[/tex]

The point (0, 20) tells us that y = 20 when x = 0. Hence:

[tex]20=a(b)^0[/tex]

Simplify:

[tex]20=a(1)\Rightarrow a=20[/tex]

So, our exponential function is now:

[tex]y=20(b)^x[/tex]

Next, the point (6, 1280) tells us that y = 1280 when x = 6. Thus:

[tex]1280=20(b)^6[/tex]

Solve for b. Divide both sides by 20:

[tex]64=b^6[/tex]

Therefore:

[tex]b=\sqrt[6]{64}=2[/tex]

Hence, our function is:

[tex]y=20(2)^x[/tex]

1. What is the measure of angle B04?
2. What is the measure of angie BDA?
3. What is the measure of angle BCA?

Answers

Using the inscribed angle theorems, the measure of the indicated angles are:

1. m∠BOA = 30°

2. m∠BDA = 15°

3. m∠BCA = 15°

What is the Inscribed Angle Theorems?

Based on the inscribed angle theorems, the following relationships are established:

Inscribed angle = 2(measure of intersected arc)Central angle = measure of intersected arc

Given:

Intercepted arc BA = 30°

1. ∠BOA is central angle

Thus:

m∠BOA = 30° (inscribed angle theorems)

2. ∠BDA is inscribed angle.

m∠BDA = 1/2(30) = 15° (inscribed angle theorems)

3. m∠BCA = m∠BDA = 15° (inscribed angle theorems)

when a number is reduced by 5 it becomes 70% of the number itself find the number

Answers

Answer: 75%

Step-by-step explanation: When you said a number is reduced by 5, it is 70%. So 70 + 5 = 75%

Answer:

16 2/3

Step-by-step explanation:

x - 5 = 0.7x

x - 0.7x = 5

0.3x = 5

x = 5/0.3 = 16 2/3

check: 50/3 - 5 = 35/3

0.7 x 50/3 = 35/3
