PLEEASE HELP ITS DUE IN 19 MINUTES PLEASE HELP PLEASE HELP!
Answer:
126
Step-by-step explanation:
This is a tricky question!
So we can quickly find the area of the whole circle through πr². That would be around 144π (remember, we are solving in terms of π, so we dont use 3.14)
Then, the circles. Through πr², we can find that the area of one circle is 9π. And since there are two circles, we can add these together to become 18π.
Now we subtract 144π from 18π to find the shaded area. 126π, and since we are doing this in the terms of π, we don't need to include that.

Step-by-step explanation:
We first have to create the roots of the graph. This can the done by creating factors based on the x intercepts as shown in the equation above. We have to make sure we change the signs of the x intercepts in order to create zeros.
We then have to square (x+0) because it does not completely cross the x axis. Finally we we multiply everything by -1 because the graph is starting from the top.
From the graph , we can see that the line of the graph passes through the points ,
(0,0)
(-1,0)
( 2, 0 )
(3,0)
These are the roots of the equation. The point on which the graph cuts the x axis are the roots of the graph . Here since the graph cuts x axis 4 times , it has 4 roots as ,
-1
2
0

Each triangle has 1 obtuse angle and 2 acute angles. A. Both triangles are isosceles. B. Only one triangle has a right angle. C. Only one triangle has an acute angle. D. Both triangles have an obtuse angle. help HELP
Answer: D. Both triangles have an obtuse angle
This is because it says "Each triangle has 1 obtuse angle and 2 acute angles" in the instructions. An obtuse angle is any angle between 90 and 180 degrees, excluding both endpoints.

What is 57 x 4?
Enter your answers in the boxes to complete the area model.
Answer:
200 + 28= 228
..................
The values of the numbers in the boxes is 57 x 4 = 200 + 28 = 228
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be represented as p
where the value of p = 57
Let the second number be represented as q
where the value of q = 4
And , A = 57 x 4
where the blank spaces in the boxes are by distributive property and
A = 57 x 4
( 50 + 7 ) 4 = ( 50 x 4 ) + ( 7 x 4 )
On simplifying the equation , we get
A = 200 + 28
A = 228
Therefore , the value of A is 228
Hence , the expression is A = 228

Answer:
[tex]y=\frac{5}{6}x+2\frac{2}{3}[/tex]

Sydney simplifies the expression 2csc(-y) with the work below. What did she do wrong? 2csc(x+y)= 2/sin(x-y)
=2/cos x cos(-y)+sin xsin(-y)
=2/cos x cos y - sin xsin y
=2/cos( x +y)
= 2 sec (x + y)
Answer:
We know that:
csc(x) = 1/sin(x)
Now we want to work with:
2csc(x+y)
The first step is:
2csc(x+y)= 2/sin(x-y)
This is correct so far.
Now we need to use the relation:
sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
Then:
sin(x - y) = sin(x)*cos(-y) + sin(-y)*cos(x)
sin(x) is an odd function, then: sin(-y) = -sin(y)
and cos(x) is an even function, then:
cos(-y) = cos(y)
Then we get:
sin(x - y) = sin(x)*cos(y) - sin(y)*cos(x)
then:
2/sin(x-y) = 2/(sin(x)*cos(y) - sin(y)*cos(x))
Now let's look at what she did:
2/sin(x-y) = 2/(cos x cos(-y)+sin xsin(-y))
Here is her error, she replaced:
sin(x - y) by cos x cos(-y)+sin(x)sin(-y)
This relation is for the cosine function, not the sine one, so here is her mistake.

1 pound (lb) = 16 ounces (oz) 1 kilogram (kg) = 1000 grams (8)
1 ton (ton) = 2000 pounds (lb)
1 ounce (oz) = 28.35 grams (g)
1 gram (g) = 1000 milligrams (mg)
1 pound (lb) = 0.454 kilograms (kg)
Answer:
ounces
Submit Answer
800 grams into ounces is 28.2, rounded to the nearest tenth.
The conversion of 800 grams into ounces is 28.2.

Answer:
Look down below!
Step-by-step explanation:
Alright, so let's start solving this
1. First we are going to be placing the x one one side and the constants (or the regular numbers) on the other side.
How to do that?
Well, we can take -3x and 20 to their other sides.
The reason for this is that we don't want to have the value with x as a negative
So we do
-3x-4 = 20
+3x -20 -20+3x
You may not understand what was about but all I did was just added 3x to both sides and subtracted 20 to both sides to make the new equation
-24 = 3x or 3x = -24
Now we can see that the x has a number it is being multiplied with so to get rid of the number we divide everything by 3
So
3x/3 = -24/3
Which results in x = -8 and voila, there is your answer!
