Answer:

Option 1

Step-by-step explanation:

Given : The function g(x)=(0.20)2^x

To find : Which option below shows the graph of the given function ?

Solution :

We know that,

The y-intercept of a function is the value of y when the value of x is equal to zero.

Substitute x=0 in the given function,

g(0)=(0.20)2^0

g(0)=0.20

This shows that graph is passing through the point (0,0.20).

In the following options on graph 1 the point passes through the point.

Therefore, Option 1 is correct.

Refer the attached figure.

The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. A wind speed of 37 miles per ho
vfiekz [6]

Answer:the output for a wind speed of 40 miles per hour is 810.8 kilowatts.

Step-by-step explanation:

The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. This means that

P is directly proportional to S

Introducing a constant of proportionality, k, it becomes

P = kS

A wind speed of 37 miles per hour produces a power output of 750 kilowatts. This means that

750 = k × 37

k = 750/37 = 20.27

The expression becomes

P = 20.27S

Therefore, the output for a wind speed of 40 miles per hour would be

P = 20.27 × 40

P = 810.8

Before leaving to visit Mexico, levant traded 270 american dollars and received 3000 mexican pesos. When he returned from mexico
Makovka662 [10]
Levant will receive about 9 american dollars when he exchanges his pesos.

According to this question, 1 american dollar is worth about 11 pesos. In order to find that, you need to divide 3000/270 which gives you around 11. In order to find out how many dollars he will receive for his pesos, you need to divide 100 by 11 which gives you about 9 dollars.

Identify the values of variables x, y, and z based on the image given of the angles formed by a transversal and parallel lines
Paul [167]

Answer:

x=62\\y=94\\z=94

Step-by-step explanation:

Let's start by identifying relevant angle theorems for two parallel lines cut by a transversal.

Alternate Interior Angles Theorem

Two angles that are on different sides of the transversal and inside of the two parallel lines are congruent (=).

Alternate Exterior Angles Theorem

Two angles that are on different sides of the transversal and outside of the two parallel lines are congruent (=).

Same-side Interior Angles Theorem

Two angles that are on the same side of the transversal and inside of the two parallel lines are supplementary (= 180).

Same-side Exterior Angles Theorem

Two angles that are on the same side of the transversal and outside of the two parallel lines are supplementary (=180).

Corresponding Angles Theorem

Two angles on a figure that correspond are congruent (=).

_

Now, let's look at the figure and apply these theorems.

z and 86 are same-side exterior angles, meaning they're supplementary:

z+86=180

Subtract 86 from both sides of the equation:

z=94

Now that we know our z value, let's recognize that z (94)corresponds to x+32, meaning they're congruent:

x+32=94

Subtract 32 from both sides of the equation:

x=62

Let's find the value of the angle:

(62)+32

Add:

94

Since the corresponding angles are of the same value, they're congruent, proving our x & z values correct.

_

Since y and the angle represented by the expression x+32 (94°) are alternate-interior angles, they are congruent:

y=94
