Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become 1.2* 10^{-7}
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become 50.08* 10^{-7}
Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are 1.2* 10^{-7} and 50.08* 10^{-7}

Avery planned a circular garden and path as shown below. The radius of the garden is 4 feet and the path around the garden is 2
Digiron [165]

Answer:

Option C) 113.0 feet squared

Step-by-step explanation:

We are given the following in the question:

Radius of circular garden = 4 feet

Length of path around garden =  2 feet

We have to find the total area of garden and path.

The garden and path together makes a bigger circle with radius

R = 4 + 2 = 6\text{ Feet}

Area of garden and path =

A = \pi R^2

Putting values, we get,

A  = 3.14\times (6)^2 = 113.04\\A \approx = 113.0\text{ square feet}

Thus, the correct answer is

Option C) 113.0 feet squared

Which choice is equivalent to the quotient below? √64/√4<br>a. √2<br>b. √4/4<br>c. √8/2<br>d. 4​
Ksju [112]

Step-by-step explanation:

you did not even try a calculator to find the result ?

64 is 8×8 or 8².

so, sqrt(64) = 8.

similarly for 4 :

4 is 2×2 or 2².

so, sqrt(4) = 2

so,

sqrt(64)/ sqrt(4) = 8 / 2 = 4

so, d. is the right answer.

A point p in the first quadrant lies on the parabola y=x^2. Express the coordinates of p as a function of the angle of inclinati
max2010maxim [7]

Answer:

  • The coordinates of the point p are:       (x,xtan\alpha )

                   

           

Explanation:

1. Name the angle of inclination of the line joining p to the origin α.

2. Find the relation between the coordinates of the point (x,y)

When you draw a line from the origin to the parabola, the intersection point, p(x,y) will have coordinates (x,y).

As per the definition of the tangent trigonometric ratio you have:

  • tan\alpha =\frac{y}{x}

From which you can clear y:

  • y=xtan\alpha =>(x,y)=(x,xtan\alpha )

Which is the expression of the coordinates of p as a function of the angle of inclination of the line joining p to the origin.
