1. Round 9.39 to the nearest whole number
2. what is the value of the expression 4^3+9 times 6

Answers

Answer 1

Answer:

Step-by-step explanation:

1.  The digits 39 are less than 50.  Round 9.39 to 9 (nearest whole number).

2.  4^3+9 times 6    This is an order-of-operations problem.  We must do exponentiation before multiplication and division, and addition and subtraction must follow multiplication and division.

4^3 = 64, so we have 64 + 9(6).

Must do multiplication before addition:  64 + 54 = 118

What are the resulting coordinates of triangle X′Y′Z′ after rotating triangle XYZ counterclockwise 90° about the origin? Question options:
A) X′ (1, 1), Y′ (1, 4), Z′ (–4, 4)
B) X′ (1, 1), Y′ (4, 1), Z′ (4, 4)
C) X′ (1, 1), Y′ (1, 4), Z′ (4, 4)
D) X′ (–1, 1), Y′ (1, 4), Z′ (4, –4)

Answers

Answer:

C

Step-by-step explanation:

Rotation 90 degrees counter clockwise rule (x,y) -----> ( -y , x )

In order to find the answer we must first find the coordinates of the pre image

The coordinates are...

x (1,-1)

y (4,-1)

z (4,-4)

Now we apply the rule stated previously

( The rule explanation: the x and y values swap and the y values sign changes. So if the y value was previously positive, after a 90° counter clockwise rotation, the y value will then be negative)

x (1,-1) -----> swap x and y values ( -1,1) ------> flip sign of new x value ( 1 , 1 )

y (4,-1) ------> swap x and y values ( -1,4) -----> flip sign of new x value ( 1 , 4 )

z (4,-4) -----> swap x and y values ( -4,4) ------> flip sign of new x value ( 4,4)

the new coordinates are X' (1,1) , Y' (1,4) , Z (4,4)

Hence the answer is C

In the diagram, point C represents the center of the sphere. Diego says that the part of the sphere labeled D is the radius. Gregoire says that the part of the sphere labeled D is the diameter of the sphere.

A sphere. C is the center and D is the diameter.
Who is correct and why?
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Gregoire is correct; the diameter is a chord that is from the center to the surface of the sphere.
Diego is correct; the radius is a chord that passes through the center of the sphere.
Diego is correct; the radius is a chord that is from the center to the surface of the sphere.

Answers

Answer:A

Step-by-step explanation: edg 2021

Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.

What is a sphere?

It is a three-dimensional figure where the volume is given as  4/3 πr³

We have,

The diameter of a sphere is a chord that passes through the center of the sphere and has endpoints on the surface of the sphere.

Therefore, the part of the sphere labeled D in the diagram is the diameter, not the radius.

The radius of a sphere is a chord that is from the center to the surface of the sphere, and it is half the length of the diameter.

Thus,

Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.

Answer:

Table 1(red)

Step-by-step explanation:

A proportional relationship will have a constant of proportionality between y and x all through the data given.

Constant of proportionality, k = y/x

Table 1 (red):

y/x = 5/1 = 10/2 = 20/4 = 5

k = 5 all through, therefore, this table show a proportional relationship between x and y

Table 2 (blue):

y/x = 1/6 ≠2/9 ≠ 4/15

This doesn't have a constant of proportionality, k, that is the same all through in the given table of values. Therefore, it doesn't show any proportional relationship between x and y
