Find the distance between the two points rounding to the nearest tenth (if
necessary).
(4,4) and (-2,-4)
Answer:
10
Step-by-step explanation:
d² = (x2 - x1)² + (y2 - y1)²
d² = (-2 - 4)² + (-4 - 4)²
d² = (-6)² + (-8)²
d² = 36 + 64
d² = 100
d = 10

Answer:
substitute the value of y into the equation 7x+3y = 35
7x + 3(x+5) = 35 (distribute 3 through the parenthesis)
7x + 3x + 15 = 35
collect the like terms
7x + 3x = 35 - 15
10x = 20 (divide both sides by 10)
x = 2
substitute x = 2 into the equation y = x + 5
y = 2 + 5
y = 7

Answer:
y = 1/2x^2 +x -15/2
Step-by-step explanation:
The vertex is the point where the graph reaches is extreme: (-1, -8). The y-intercept is (0, -7.5). The x-intercepts are (-5, 0) and (3, 0).
When the quadratic is written in the form ...
y = x^2 +bx +c
the value of b is the opposite of the sum of the x-intercepts. The value of c is their product. These facts would give ...
y = x^2 -(-5 +3)x +(-5)(3) = x^2 +2x -15
The constant in this equation is -15, which is the value y has when x=0. Our actual y-intercept is half that, so the graph we see is this equation scaled by a factor of 1/2:
y = 1/2x^2 +x -15/2
_____
Alternate solution
You can start with the vertex form.
y = a(x -h)^2 +k . . . . . . . vertical scale factor 'a' and vertex (h, k)
On the graph, the vertical scale factor is the vertical difference between the low point (vertex) and the point that is 1 unit right or left. Here, that is ...
-7.5 - (-8) = 0.5 = a
We've already said the vertex is (h, k) = (-1, -8), so the vertex form equation is ...
y = 0.5(x +1)^2 -8
We know the square of a binomial is (a+b)^2 = a^2 +2ab +b^2, so we have ...
y = 0.5(x^2 +2x +1) -8
y = 0.5x^2 +x +0.5 -8 . . . . . eliminate parentheses
y = 0.5x^2 +x -7.5

A Ferris wheel with a radius of 19m rotates once every 56 seconds. The top of the
wheel is 42.5m above the ground.
Determine a sine and cosine equation of the function that gives the rider's height
above the ground in metres, as a function of time, in seconds, with the rider starting
at the bottom.
Answer:
(First of all its 20 points not 40 but any ways) A ferris wheel has a raidus of 20 m. Passengers get on halfway up on the right side. The direction of rotation is counter clockwise. The bottom of the ferris wheel is 2 m above ground. It rotates every 36 seconds. Determine height above the ground after 15 seconds algebraically. Determine seconds to the nearest tenth when height is 38 m above the ground algebraically.
**
let t=seconds after wheel starts to rotate.
let h=meters above ground after wheel starts to rotate
..
The formula I got: h(t)=20sin(πt/18)+22
This is close to the formula you got, except I left the negative sign out since passengers start to rise after the wheel starts going counter-clockwise.
..
After 15 seconds:
h=20sin(15π/18)+22
=20sin(5π/6)+22
=20*(1/2)+22
=32 m
..
When h=38 m
38=20sin(πt/18)+22
38-22=20sin(πt/18)
20sin(πt/18)=16
sin(πt/18)=16/20=4/5=.8
arcsin(.8)=0.927
πt/18=0.927 (radians)
t=(.927*18)/π≈5.31
..
height above the ground after 15 seconds≈38 m
seconds elapsed when height is 38 m above ground≈5.3 seconds

Which value is closest to the perimeter of the window
Answer:
9.82 feet
Step-by-step explanation:
the perimeter of the window is the circumference of a semi-circle with a diameter of 5
P = (πd)/2 (divided in half because it's only half a circle)
P ≈ 3.14(3.5) which is approx 11
11 is closest to 9.82
Answer:
9.82 Is the Closest
Step-by-step explanation:
First of all, you can see its a half circle, meaning if we make it a full circle, the length of the center is 5, so the full circle's area is about 19.5-20. Now to find the area of the half circle/windows we get 9.75 - 10. The only number between that is 9.82, which should be you answer.

Write this expression in the fewest number of terms: x+3y+2x+10+2y+12
Answer:
3x+5y+22
Step-by-step explanation:
Answer:
3x + 5y + 22
Step-by-step explanation:
Given expression:- x + 3y + 2x + 10 + 2y + 12
Here, you can add all the 'x' terms together and 'y' terms together.
There is an 'x' and '2x'.
On adding them, you get 2x + x equals 3x.
Then add the 'y' terms
There is a '3y' and a '2y'. On adding them, you get 3y + 2y equals 5y.
Then add the numbers that are left. 12 and 10.
12 + 10 equals 22.
Then take all the values we got after addition:- 3x, 5y and 22.
2x, 5y and 22 cannot be added together. So, the expression in the simplified form would be:-
3x + 5y + 22Explain how a piece of food when eaten is digested and absorbed by the human body

Answer:
The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
Answer & Explanation:
When humans chew food, it is chemically and physically broken down into smaller molecules. Your teeth physically crush the food and enzymes in your saliva break down the food into smaller pieces. Then your food goes through your esophagus and begins the digestion process. When the food reaches the stomach, the stomach walls pound the food to make it into smaller chunks of food. Hormones secreted in the stomach walls release acids and enzyme juices that chemically dissolve the food into even smaller pieces. The liver, pancreas, and gallbladder are major parts of the digestive process as well. They produce digestive juices and transfer bile to prepare for the next stage. After the food has been in the stomach for three hours, the food is now a liquid called chyme and is ready to move into the small intestine! The liver sends the bile to the gallbladder that secretes it into the duodenum. Then it dissolves the fats in the chyme so they can be digested by the juices from the pancreas and intestines. The enzyme juices break down the fat molecules in the chyme into fatty acids. The enzymes carry out the final deconstruction of proteins into amino acids. This happens in the small intestine lower region that is coated with villi. The villi maximizes molecule absorption and transfers it into the bloodstream. The blood then feeds it to the body’s organs and tissues.
That is whole process of digestion. Hope this helps! :3
