The circumference of a circle is22 cm find the radiusof the circle

Answers

Answer 1

Answer:

Answer:

3.5cm

Step-by-step explanation:

$C = 22cm\nr = ?\n\nC = 2\pi r\n\nr = (C)/(2\pi) \n\nr = (22)/(2(3.14))\n \nr = (22)/(6.28) \n\nr = 3.5$

Some algae contains up to 50% oil by weight. How much oil is in a 7.3-ounce sample of this type of algae?This would help if you could solve anyone.

Answers

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

$(1)/(2)$ of 7.30 = $3.65$

next question : Find the following determinant by hand.

answer is : 1

Next question : In mathematics, a pattern may suggest a conclusion, but it is not proof of it. Next you will prove that the determinant of a rotation matrix (CCW about the origin) must be 1. Luckily, there is the general rotation matrix you can use.

Answer : cos^2x + sin^2x

/next question: In the lesson, you used the following matrices to create reflections

Answer: All these reflections resulted in CONGRUENT figures.

next question: Find the determinant of each of these: answer: - 1

next question: A • At =

c d

where At is the transform of A. answer: a=1 b=0 c=0 d=1

next question: Repeat this process for the other three matrices. The product of a reflection matrix and its transpose is the identity matrix

Choose the correct choice for the matrix after applying the transformation to the triangle: A

The resulting matrix creates an image that is to the original triangle.: not similar
