Answer:
Step-by-step explanation:
f(x)=x²-5x+7
f(2)=2²-5.2+7=4-10+7=11-10=1
f(-1)=(-1)²-5.(-1)+7=1+5+7=13
f(1/3)=(1/3)²-5(1/3)+7=1/9-5/3+7=49/9
∴, f(2)-f(-1)+f(1/3)
=1-13+49/9
=58/9-13
=-59/9

Answer:
Janet reads 13.865 pages in 4.7 minutes.
Step-by-step explanation:
Given that Janet can read 2.95 pages of a book in a minute.
- unit rate = 2.95 pages/per minute
As she reads for 4.7 minutes.
We just need to multiply 4.7 minutes with 2.95 to determine total pages she would read in 4.7 minutes.
i.e.
4.7 × 2.95 = 13.865 pages
Therefore, Janet reads 13.865 pages in 4.7 minutes.
The value of the <em>shaded</em> area is approximately 34.907 square centimeters.
<h3>How to calculate the area between a rhombus and a circle</h3>
According to the description in statement we prepared a representation of the figure in the image attached below. The <em>shaded</em> area is equal to the area of the <em>circle</em> sector (
), in square centimeters:
(1)
Where:
- Length of the radius, in centimeters.
- Angle of circle arc, in degrees.
If we know that
and
, then the area of the circle is:

To solve this, set up a proportion, crossmultiply, and solve for x.
Let x = the unknown amount of cases in 60 minutes.

44x = 50(60)
44x = 3000
Divide both sides by 44 to isolate variable x
x = 3000 / 44
x ≈ 68.1818 (the 18s repeat forever)
Rounding to the closest case and assuming the rate stays constant, you would get
approximately 68 cases in 60 minutes. If you need not round to the nearest case, you would get approximately 68.18 cases in 60 minutes.
