Write 5.1 x 10^-3 as an ordinary number.

Answers

Answer:

This would be .0051 as an ordinary number.

Step-by-step explanation:

In order to turn this into a normal number, simply move the decimal place the same amount of times as the exponent.

So this would result in .0051

Based on the drawing, Which can be used to prove PQR ≅ STV?1. SSS
2. SAS
3. ASA
4. AAS

Answers

Answer:

Option (2) is correct.

Based on the drawing, SAS can be used to prove PQR ≅ STV

Step-by-step explanation:

We have to find the criterion by which the two given triangle can be prove similar from the given options.

Consider, the given triangles from the drawing given

ΔPQR and ΔSTV,

PR = VS (Given)

∠QRP = ∠TVS ( Given)

and, QR = TV (given)

Thus, PQR ≅ STV ( SAS CRITERION)

For SAS criterion , we need to show that two sides and the angle between those sides are equal .

Thus, option (2) is correct.

Answer:

SAS

Step-by-step explanation:

GIVEN: PR ≅ SV (side)

GIVEN: ∠R ≅ ∠V (angle)

GIVEN: QR ≅ TV (side)

The largest state in the US is Alaska, covering 663,267 square miles (including water). What is the approximate radius of a sphere with the same surface area as the area of Alaska?

Answers

So we wan't to calculate the radius of a sphere that has the area of Alaska that is A=663.267 square miles. First, lets see what is the formula for the area of the sphere: A= 4*pi*r^2. Here we can solve the equation to get the radius: r^2=A/(4*pi) and the last step is: r= sqrt ( A/(4*pi) ). After we input the numbers we get: r= 224.54 miles.

Which of the following graphs represent functions Circle your answers. If it is a function, state the domainand range. If the graph is not included, make a table and graph the function by hand.

Answers

Answer:

Step-by-step explanation:

A). y = |2x - 3| + 1

Domain of function is defined by the x-values (Input values) and Range by the y-values(Output values).

From the graph,

Domain : (-∞, ∞)

Range : [1, ∞)

B). Table of the input-output values of the function,

y = x² - 2x + 1

x -2 -1 0 1 2

y 9 4 1 0 1

By graphing the function as attached,

Domain of the function : (-∞, ∞)

Range of the function : [0, ∞)

C). x² + y² = 3²

Domain of the function : [-3, 3]

Range of the function : [-3, 3]

D). x = 5

Domain of the line : [5, 5]

Range of the line : (-∞, ∞)
