Work out the value of R. Give your answer in standard form to an appropriate degree of accuracy.
Mumz [18]

Answer:

R = 8,228,571.43 (Approx)

Step-by-step explanation:

Given:

R = x²/y

x = 4.8 x 10⁵

y = 2.8 x 10⁴

Find:

Value of R

Computation:

R = x²/y

R = (4.8 x 10⁵)²/ (2.8 x 10⁴)

R = 23.04 x 10¹⁰ / (2.8 x 10⁴)

R = 8.22857.. x 10⁶

R = 8,228,571.43 (Approx)

The graph of a proportional relationship contains the point (20, 4).
soldier1979 [14.2K]

Answer:

y=\frac{1}{5}x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

point (20,4)

Substitute the values and solve for k

k=y/x

k=\frac{4}{20} =\frac{1}{5}

therefore

the equation of the line is equal to

y=\frac{1}{5}x

What is the value of 7 to the 4th power
zhenek [66]

Answer:

The value is 2401

Step-by-step explanation:

First we need to understand what's means 7 to the 4th power, or 7^4.

7 is the power base, the power base is the number that we are going to repeat the number of times the exponent says.

4 is the exponent, which will tell us how many times to multiply 7.

So , then we would have

1)                7 x 7 x 7 x 7

2)                  49 x 7 x 7

3)                     343 x 7

4)      finally       2401

Using the diagram, what is the value of x? <br><br> A. 110°<br> B. 30°<br> C. 60°<br> D. 120°
Sidana [21]

The value of x would be

D. 120 degrees

That is because a line is 180 degrees, subtract 60 degrees since angle is going to be 60 degrees (equilateral triangle) like this:

180 - 60 = 120 degrees
