Answer:

The correct option is C and the scale factor which converts P to Q is 3.

Step-by-step explanation:

From the figure it is clear that the diameter of circle P is 1.5 feet and the diameter of circle Q is 4.5 feet.

Circle P is pre-image and circle Q is image.

Scale factor is the proportion of diameter of image and pre-image.

k=\frac{4.5}{1.5}

k=3

Therefore the scale factor which converts P to Q is 3 and correct option is C.

Answer: C

Step-by-step explanation:

To find the scale factor between circle P and circle Q, divide the diameter of circle Q by the diameter of circle P, 4.5 ft÷1.5 ft = 3. The scale factor between circle P and circle Q is 3.

A set of data is summarized by the stem and leaf plot below.
Andre45 [30]

Answer:

30 values ; greater than or equal to 10 and less Than or equal to 39

Step-by-step explanation:

Counting the number of leaves in the plot, we have 30 leaf values. This gives the number of dataset.

The minimum value is the number created by the combination of the least stem value and the lowest leaf value, which is 10

The maximum value is obtained from the combination of the highest stem and leaf value. The highest value is 39

Which equation represented the line shown on the coordinate plane below?
Tju [1.3M]

Answer:

D

y=-\frac{1}{4}x

Step-by-step explanation:

So we are given a line and are asked to find the equation for the line. To do this we need 2 things: the slope and a point on the line (preferable the y-intercept). Remember, the equation for a line in y-intercept form is:

y = mx + b

Where m is the slope and b is the y-intercept.

From looking at the image, we can see that the line intercepts the y-axis at y = 0. Thus, the y-intercept is 0. So our equation for the line becomes:

y = mx

Where m is the slope. Now we must find the slope in order to find the equation for the line. Remember:

m=slope=\frac{rise}{run}=\frac{change-in-y}{change-in-x}

Notice how the y-value of the line decreases by 1 when the x-value increases by 4. This means that we can use the -1 for the rise (or the change in y) and 4 for the run (or the change in x). Plugging in we get:

m=slope=\frac{rise}{run}=\frac{-1}{4}=-\frac{1}{4}

Thus, our slope would be -1/4. Plugging into our equation for the line we get:

y=-\frac{1}{4}x

Thus, our equation would be y=-\frac{1}{4}x.

Our answer would be D y=-\frac{1}{4}x.

I hope you find my answer to be helpful. Happy studying.
