I'll Give Branslist If Answer Is Correct!

Answer 1

Answer:

sinθ = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Using the Pythagorean identity

sin²θ + cos²θ = 1 , then

sin²θ + ([tex]\frac{\sqrt{5} }{3}[/tex] )² = 1

sin²θ + [tex]\frac{5}{9}[/tex] = 1

sin²θ = 1 - [tex]\frac{5}{9}[/tex] = [tex]\frac{4}{9}[/tex] ( take the square root of both sides )

sinθ = [tex]\sqrt{\frac{4}{9} }[/tex] = [tex]\frac{2}{3}[/tex]

Add the following lengths: 32'11"+11'3''

Answers

Answer:

44'2"

Step-by-step explanation:

32'11"+11'3' = 43'14" = 44'2"

Answer:

44'2"

Step-by-step explanation:

Starting with 32' 11", we'll add the 3" from the second number first. That will give us 32' + 14". Every 12" = 1 more foot, so that converts to 33' 2". Now add the 11' from the 11'3", and you have 44' 2". Does that make sense? Happy to answer any questions.

polynomial in the form ax^2+b+c

Answers

Given:

The polynomial is:

[tex]-7-\dfrac{1}{2}x+x^2[/tex]

To find:

The standard form [tex]ax^2+bx+c[/tex] of given polynomial and then find the values of a,b,c.

Solution:

The given polynomial is:

[tex]P(x)=-7-\dfrac{1}{2}x+x^2[/tex]

After arranging the terms, it can be written as:

[tex]P(x)=x^2-\dfrac{1}{2}x-7[/tex]

On comparing this polynomial with [tex]ax^2+bx+c[/tex], we get

[tex]a=1,b=-\dfrac{1}{2},c=-7[/tex]

Therefore, the standard form of the given polynomial is [tex]x^2-\dfrac{1}{2}x-7[/tex] and the required values are [tex]a=1,b=-\dfrac{1}{2},c=-7[/tex].

what is the slope of the line?

Answers

Answer:

slope=7/4

Step-by-step explanation:

you can find the slope of the line from a graph using the formula rise/run, where rise is the change in y and run is the change in x

let's start with a clear point; for example, (-1,-3)

we need to go up, down, left, or right to get the rise/run

up/down is considered the rise

left/right is considered the run

if we go up or to the right, that's considered a positive move

if we go down or to the left, that's considered a negative move

we'll go from (-1,-3) to another clear point, like (3,4) for example

starting at (-1,-3):

go up 7, to the point (-1,4)

then move 4 to the right to get to the point (3,4)

we went up 7, so our rise is 7

we moved to the right 4, so that is our run

our slope then is 7/4

Figure A is a scale image of Figure B. What is the value of x? Pls answer asap!

Answers

Answer: Answer: The required value of x is 12 units.

Step-by-step explanation:  Given that the figure A is a scale image of figure B.

We are to find the value of x.

Since figure A is the scale image of figure B, so both the figures are similar to each other.

Also, the corresponding sides of the similar figures are proportional, so we get

Thus, the required value of x is 12 units.

The radius of a circle is 10 meters. What is the angle measure of an arc 3 meters long?
{=37 m
=10 m
Give the exact answer in simplest form

Answers

Answer:

Ф = 0.3 radians

Step-by-step explanation:

The arc length formula is s = rФ.  Solving for the angle measure Ф, we get:

Ф = s/r

and so with r = 10 m and s = 3 m, we get Ф = 3 m / 10 m = Ф = 0.3 radians
