By changing their exponent to negative.

Ex.
$\frac{1}{ {x}^{2} } = {x}^{ - 2} \\ \frac{2}{y} = 2 {y}^{ - 1}$

What is the circumference of a circle with a diameter of 5 feet? Use 3.14 for π.

Aloiza [94]

Answer:

31.4 feet or 957.072 centimetre-square

Step-by-step explanation:

We can convert the feet to centimetre or work with it that way

Formula for circumference

C=2TTr^2

C=2*3.14*5

C=31.4 feet

Convert to centimetres

Each feet equal 30.48cm

31.4 feet will be

31.4*30.48= 957.072 cm^2

PLEASE HELP!!!!! A satellite telescope has a parabolic dish. Satellite signals are collected at the focal point (focus) of the

-BARSIC- [3]

The dish illustrates operations on a parabola.

The depth of the parabolish dish is 160 feet.

The bowl is said to be a parabola.

So, we have:

$\mathbf{(x -h)^2 = 4p(y - k)}$

Where:

$\mathbf{Focus: p = 40}$

$\mathbf{Vertex:(h,k) = (0,0)}$

From the question, the diameter is 160 feet.

So, the radius (r) is:

$\mathbf{r = \frac{160}{2} = 80}$

So, the coordinate of the depth of the parabola would be:

$\mathbf{(x,y) = (60 + 100,y)}$

$\mathbf{(x,y) = (160,y)}$

Substitute these values in $\mathbf{(x -h)^2 = 4p(y - k)}$

So, we have:

$\mathbf{(160 - 0)^2 = 4 \times 40 \times (y -0)}$

$\mathbf{160^2 = 160y}$

Divide both sides by 160

$\mathbf{160 = y}$

Rewrite as:

$\mathbf{y = 160 }$

Hence, the depth of the parabolish dish is 160 feet.

MariettaO [177]

Answer:7

Step-by-step explanation:

This can be solved by Venn-diagram

Given there are total 5 students who want french and Latin

also 3 among them want Spanish,french & Latin

i.e. only 2 students wants both french and Latin only.

Also Student who want only Latin is 5

Thus Student who wants Latin and Spanish both only is 11-5-3-2=1

Students who want only Spanish is 8 Thus students who wants Spanish and French is 4

Similarly Students who wants Only French is 16-4-3-2=7
