Answer:
x : __ - 2 __ -1 ___0 ___ 1 ___ 2 ___ 3
y: ___ 5___ 2___ 1 ___ 2____5 ___ - 3
Step-by-step explanation:
Table of values for part A
Equation : y = x² + 1
x : __ - 2 __ -1 ___0 ___ 1 ___ 2 ___ 3
y: ____ ___ ___ 1 __ ___5 __ - 3
Substitute the value of x to obtain the missing values _
x = - 2
y = (-2)² + 1 = 4 + 1 = 5
x = - 1
y = (-1)² + 1 = 1 + 1 = 2
x = 1
y = (1)² + 1 = 1 + 1 = 2
What is the volume of a cone with a diameter of 8 in and a height of 5 in?
Answer:
V=80π/3 or V=83.78
Step-by-step explanation:
The volume is
V=πr^2h/3
r=4 (because the radius is half the diameter)
h=5
V=π16*5/3
V=80π/3
Answer:
83.73
Step-by-step explanation:
volume = (1/3) · π · r2 · h
volume = (1/3) x 3.14 x 4^2 x 5
volume = (1/3) x 3.14 x 16 x 5
3.14 x 16 x 5 = 251.2
1/3 x 251.2
83.73

Each quadrilateral below is a parallelogram. Find the missing measures
Answer:
GH = 13
FG = 20
<F = 78
<G = 102
<H = 78
Step-by-step explanation:
Since there are 5 measures that are missing, we will do each one in a different part.
1. The side length of GH is 13. Since this is a parallelogram, the opposite side of your original side is congruent, meaning that its the same. So, knowing that the opposite of FI is GH, we can say that GH is 13 units long.
2. We can use the same logic for number 2, when finding FG. Since HI is 20. we can say that since the corresponding side is also congruent to our original length, they are equivalent. Basically meaning they are the same
3. a. For finding F, we will need to use a different method. Since a parallelogram is somewhat like a transversal we can use that to our advantage. (If you don't know what a transversal it, look at part B instead) Since we know that angle I is 102, and both line FG and HI are parallel, the angles are basically adjacent, when switched. So we should see that it would have to be 78. Meaning that F is 78.
3. b. If you don't understand what a transversal is, we can still figure it out. Knowing that the figure is a closed shape, along with knowing that its a parallelogram, we can say that if we were to sum the angles F and I, we would get 180. 180-102=78, so F is 78.
4. Since we can use a transversal or just pure logic to say that angle G and I are equivalent, meaning that G is 102.
5. This one is exceptionally simple, just for the fact that we have answered the previous questions. We have H left, which is not only equivalent to F, but using 3. b. we can say that its would only make sense that H is 78 as well, to sum up that half to 180.

Final answer is -15/8
I hope this helps you!
Have a nice day! :)
-
:D
Step-by-step explanation:
Slope is rise over run. This means your y is over your x. Start with subtracting your y values. It doesn't matter which way, just make sure you do the same with the x values. For this, I'll do it 6 - -9. The two negatives cancel out and make a positive, so your y value is 15. Now, do the same to the x values. -9 - -1 is -8. You're left with 15/-8. Since this can't be simplified, this is your final answer. Hope I helped!

You measure 3 inches between your house and the movie theater. How many miles is in from your house to the movie theater?
Answer:
4.734 * 10^-5 miles
Step-by-step explanation:
Given that:
Distance between House to movie theater = 3 inches
Expressing the distance in miles :
Converting inch to miles
1 inch = 1.578 * 10^-5 miles
3 inches = (3 * 1.578*10^-5)
3 inches = 4.734 * 10^-5 miles

The arrow of this spinner was spun 60 times. On 45 out of 60 times, the arrow landed on a section with a multiple of 4. What was the experimental probability of the arrow landing on a section labeled with a multiple of 4?
Experimental or Theoretical?
Answer:
Step-by-step explanation:
The experimental value of probability of the arrow landing on a section labeled with a multiple of 4 is 3/4 or 0.75
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
The probability that the arrow lands on a section labeled with a multiple of 4 is an experimental probability since it is based on the results of an actual experiment or trial.
The experimental probability is given by:
Experimental probability = Number of times the event occurred / Total number of trials
In this case, the event is the arrow landing on a section labeled with a multiple of 4, and the total number of trials is 60.
From the given information, we know that the arrow landed on a section labeled with a multiple of 4 on 45 out of 60 times.
So the experimental probability is:
Experimental probability = 45/60
Simplifying:
Experimental probability = 3/4
Hence , the experimental probability of the arrow landing a multiple of 4 is 3/4 or 0.75

How can canyons change because of erosion ? I will mark brainliest
Answer:
Ice forces the cracks to become larger and larger, eroding bits of stone in the process. During brief, heavy rains, water rushes down the cracks, eroding even more rocks and stone. As more rocks crumble and fall, the canyon grows wider at the top than at the bottom.
50,60,72 find the 8th term airthmetic and geometric sequence
Answer:
8th term is 179.15904
Step-by-step explanation:
The sequence is geometric with a common ration = 6/5
r = 60/50 = 72/60 = 6/5
Use the formula
[tex]a_{n} = ar^{n - 1}[/tex]
In your case a = 50, r = 6/5 and n = 8
[tex]a_{8} = 50(6/5)^{8 - 1} \\ = 50(6/5)^{7} \\ = 50(279936/78125)\\ = 179.15904[/tex]

What is the approximate volume of the whole shape? Round your answer to the nearest tenth. Use 3.14 to approximate pi. (Show your work.)
Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*[tex]\pi r^{3}[/tex]
=(1/2)*(4/3)*3.14*[tex]4^{3}[/tex] (4*4*4=64)

=150.72
total volume=133.97+150.72

The monthly membership costs include a $10 basic fee plus $2 for each DVD she rents. Which equation describes v, the number of DVDs Ingrid can rent, based on T, the amount she spends for membership costs per month?
A. v= t/2 - 5
B. v= t/2 - 10
C. T= v/2 - 10
D. T= v/2 - 5
Answer:
A) v = T/2 - 5
Step-by-step explanation:
T = 10+2v
2v = T-10
v = (T-10)/2 = T/2-5
The equation that describes no. of DVDs that Ingrid can rent is A. v = (T/2) - 5.
What is an equation?An equation states that terms on both sides of the equality sign are equal.
The monthly membership costs 10 dollars, and The rent for each DVD costs 2 dollars.
No. of DVDs that can be rented is denoted by v based on T.
The equation that describes the total cost of renting DVDs is,
T = 2v + 10.
∴ The equation that describes no. of DVDs that can be rented is
2v = T - 10.
v = (T/2) - 5.
