Answer:

(2,4)

Step-by-step explanation:

Step 1: Understand the question

We know moving left DECREASES the x value and moving right INCREASES the x value.

We need to move 6 units back to the right to get the original coordinate

Step 2: Solve

(-4 + 6, 4)

(2, 4)

Step 3: Therefore statement

Therefore you started at (2, 4)

Use cylindrical coordinates. Find the volume of the solid that lies within both the cylinder x2 + y2 = 25 and the sphere x2 + y2

Inessa05 [86]

Answer:

Step-by-step explanation:

we are asked to find the volume of solid that lies within both the cylinder

$x^2 + y^2 = 25$

and

the sphere $x^2 + y^2 + z^2 = 49.$

Conversion from rectangular to cylindrical is

$x=rcost\\y = rsint\\z=z$

|J| =r

In cylindrical coordinates the volume is bounded by the cylinder r=5 and

$r^2+z^2 =49$

Hence we can write volume as

$\int \int \int dxdydz\\=\\\int _0^5 \int_0^{2\pi} \int_{-\sqrt{49-r^2} } ^{\sqrt{49-r^2} rdzdtdr\\= 2\pi \int _0^5 (2\sqrt{49-r^2} rdr\\=4\pi (-(49-r^2) (2/3)\\= \frac{4\pi}{3} (343-48\sqrt{6} )$

if a pineapple costs $p and a mango costs $q, write an algebraic expression, in dollars, in terms of p and q for the total cost

nadezda [96]

Answer: 5p + 3q

Explantation: 5 pineapples is going to be multiplied by p, the cost of 1. And 3 mangoes are going to be multiplied by q, the cost of 1. And adding the two totals together gives you the total cost.

Find the smallest whole number by which 396 should be divided so as to get a perfect square numberPLS FAST ...............

emmainna [20.7K]

Answer:

Steps:

Find the prime factores of 396.

These are 2x2x3x3x11.

Circle all the pairs and pick out the one that does not have a pair. In this case it is 11.

You can either multiply 396 by 11 or divide by 11 to make it a perfect square.

Since the question asks for divide. It’s 11

Hope this helps.

Good Luck

Do you know what the word avionics is? If so define it, if not look it up and define it. How do you think robots will play an im

aleksley [76]

Answer:

I think robots will play an important role in avionics because robots may later be able to control what your plane does and they will have to be able to view avionics to control the plane. They could also make avionics better.

Step-by-step explanation:

Avionics is electronics in aviation.
