b) ✓159 is not a whole number

Hey there!

The answer to your question is B.) √156

Whole numbers are numbers greater than 0 that, when changed to a fraction in its simplest form, the denominator would be 1.

The square root of a number is a whole number that, when multiplied by itself, equals the original number. Example: √4 = 2, because 2 x 2 = 4

So, we will find the square root of each of the following:

√144 = 12

√156 = 12.489996...

√169 = 13

√196 = 14

Therefore, √156 is not a whole number, because it cannot be simplified into a fraction over 1.

3. Marie planted a tree a few years ago and wanted to see how much it had grown. Marie
measures the angle from a point A to the top of the tree to be 34 degrees. She measures her
distance to be 8 meters from the base of the tree. How high is the tree to the nearest tenth of a
meter?

Answers

Answer:

5.4 m

Step-by-step explanation:

Given

The top of the tree, the point A and the base form a right triangleHorizontal leg = 8 mVertical leg = the height of the tree = xAngle A = 34° is opposite to the three

Use the ratio to find the value of x:

opposite / adjacent = tan Ax/8 = tan 34°x = 8 tan 34 degreex = 5.4 m (rounded)

convert the equation 10x - 3y= -15 into slope intercept form​

Answers

Answer:

y = -10/3x - 5

Step-by-step explanation:

slope intercept form:

y = mx + b

10x - 3y = -15

subtract 10x from both sides of the equation

10x - 10x - 3y = -15 - 10x

3y = -15 - 10x

3y = -10x - 15

divide the equation by 3

3y/3 = -10x/3 - 15/3

y = - 10x/3 - 5

5. Line 2x -3y = 6 is transformed by a dilation a scale factor of 2 and centered at the (3, 0). What is the equation of the line after the dilation?

Answers

Answer:

2x-3y=6

Step-by-step explanation:

To keep it short, since one of the points o the equation 2x-3y=6 is on the line and is the center of the non rigid transformation we can stretch or compress however long we want, the equation or slope will stay the same since slopes are proportional for example the slope in this problem is 2/3. If we multiply the line by a scale factor of 2, the lines are similar and the slope is 4/6 which is the same as 2/3. So the equation stays the same
