Find the intercept and slope in the graph, and find the aquation for the function.
Answers
Answer:
Slope = 3
y intercept = -8
y = 3x - 8
Step-by-step explanation:
From the table shown, we can make use of the coordinate points
(0, -8) and (1, -5)
Slope m = y2-y1/x2-x1
m = -5-(-8)/1-0
m = -5+8/1-0
m = 3/1
m = 3
Slope = 3
The standard form of an equation is y = mx+b
b is the y intercept
Substitute m = 3 and (0, -8) into y = mx+b
-8 = 3(0) + b
-8 = b
b = -8
Hence y intercept is -8
Get the required equation
Recall that y = mx+b
y = 3x + (-8)
y = 3x - 8
This gives the required equation

area of unshaded sector =
Answers
Answer:
Area of the unshaded sector = 113.4 sq units
Area of the shaded sector = 200.6 sq units
Step-by-step explanation:
First let us calculate the area of the circle
Area of the circle = πr²
radius r = 10units
Area of the circle = π(10)²
Area of the circle = π(100)
Area of the circle = 3.14(100)
Area of the circle = 314 sq. units
Area of a sector = theta/360 * πr²
Area of the unshaded sector = 130/360 * 314
Area of the unshaded sector = 13/36 * 314
Area of the unshaded sector = 113.389 sq units
Area of the unshaded sector = 113.4 sq units
Area of the shaded sector = Area of circle - Area of the unshaded sector
Area of the shaded sector = 314 - 113.89
Area of the shaded sector = 200.6sq. units

Tyler has a stack of cards. He picks a card, records the color, and returns the card to the stack. He repeats this 60 times and chooses a red card 24 times. What is the experimental probability of choosing a red card from the stack?
Answers
Answer:
24/60 = 2/5
Step-by-step explanation: dont have one
Answer:
2/5, or 40%
Step-by-step explanation:
The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.

Brian and sonya each have a container. They mark their containers to show tenths. Brian and sonya both fill their containers with 0.7 units of juice. However, brian has more juice in him container. Explain how this is possible.
Answers
Answer:
Step-by-step explanation:
Brian could have more juice than Sonya in actual sense, This is because the representation used, that is the container has been calibrated to show tenth. This means that decimal values of juice in the container will not show explicit volume beyond tenth. Hence the volume will be rounded.
For instance, if the actual volume of juice Brian has Is 0.74 and that owned by Sonya is 0.69. In actual sense, 0.74 > 0.69 . However, if both pour their juice into the calibrated container, Brian's volume will be rounded to the nearest tenth as 0.7 and Sonya's (0.69) will also be rounded to 0.7.
But in actual sense, Brian has more Juice than Sonya.

- 12 = 6y +18-9y
Answers
Answer:
[tex] \boxed{y = 10} [/tex]
Step-by-step explanation:
-12 = 6y + 18 – 9y
[Group like terms 6y and -9y]
-12 = (6y – 9y) + 18
[Simplify the expression]
-12 = -3y + 18
[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]
-12 = -3y + 18
–18 –18
-30 = -3y
[Divide by -3 from both sides, division property of equality, to get the variable y by itself]
-30 = -3y
÷(-3) ÷(-3)
10 = y
[Symmetric property of equality, if b = a, then a = b]
y = 10

=> Area = 16π cm^2
=> Area of small circle = 4π cm^2
=> there are two circles hence both area =
8π cm^2
=> now, Area of shaded region = 16π cm^2 - 8π cm^
=> Area = 8π cm^2

Answer:
Isosceles and Right
Step-by-step explanation:
An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.
Answer:
Isosceles and right
Step-by-step explanation:
We have a picture of triangle and are asked to name it, look at definitions below :
Isosceles - Geometrical figure with three sides and three angles
Right - Triangle where one angle is a right angle (90°)
Scalene - Triangle where all three sides have different lengths
Acute - Triangle where all three sides are less than 90°
If we look at the triangle, we can tell that it has three sides and three angles, therefore isosceles must be in one of the answer choices. Crossing out the options scalene and acute / scalene and right.
Now we have two options and we need to determine whether this triangle is an acute triangle or is a right triangle.
To figure out so we can look at the angle in the bottom left, which when measures equals to 90°. Therefore making it a right triangle and crossing out the other option.
Our answer left is Isosceles and Right.

To find the slope of the line, pick two dots on that are EXACTLY on the grid.
I picked (0,3) and (2,2)
First, count how many units down the two points are from each other
I counted one.
Then, count how many units they are away from the side.
I got 2.
Slopes are rise over run or y over c so the slope is 1/2
The line is negative, too as it is going down so the slope is negative.
Therefore, the slope is -1/2 and only one option have a slope of -1/2 and it’s J
Also, to know which number is the slope look for the number before the x. In slope intercept form, that is the slope.
