y
Answers
Answer:
The values of y for each value of x are:
[tex]x = -3, y =2[/tex]
[tex]x = -2\: , y =-2[/tex]
[tex]x = -1\: , y =-4[/tex].
[tex]x = 0\: , y =-4[/tex]
[tex]x = 1\: , y = -2[/tex].
[tex]x = 2\: , y =2[/tex]
[tex]x = 3\: , y = 8[/tex]
Step-by-step explanation:
We have all the values of x, they are from -3 to 3 passing for 0.
Now, we know that y is a quadratic function (y=x²+x+4)
Therefore, we just need to put each value of x into the quadratic equation to find each y value.
When:
[tex]x = -3, y = (-3)^2+(-3)-4=2[/tex]
[tex]x = -3\: , y = 2[/tex]
We can do this for all values of x, so we will have:
[tex]x = -2\: , y = (-2)^2+(-2)-4=-2[/tex]
[tex]x = -1\: , y = (-1)^2+(-1)-4=-4[/tex].
[tex]x = 0\: , y = (0)^2+(0)-4=-4[/tex]
[tex]x = 1\: , y = (1)^2+(1)-4=-2[/tex].
[tex]x = 2\: , y = (2)^2+(2)-4=2[/tex]
[tex]x = 3\: , y = (3)^2+(3)-4=8[/tex]

A water tank in the shape of a pyramid has a rectangular base with dimensions of 10 feet by 15 feet. The height of the rectangular pyramid is 12 feet. Water fills half the volume of the water tank. How many more cubic feet of water is needed to finish filling the water tank?
(Explanations are appreciated along with your answer.)
Answers
600ft³ will be the required volume
Volume of pyramidThe formula for calculating the volume of the rectangular prism is expressed as:
V = 1/3lwhGiven the following information
l = 10 feet
w = 15feet
h = 12 feet
Get the volume
V = 1/3(10 * 15 *12)
V = 1/3(1800ft³)
V = 600ft³
Hence 600ft³ will be the required volume

Use the GCF and the distributive property to find the sum of 22+33
Answers
Answer:
22 + 33 = 55 the GCF of 22 and 33 is 11
Step-by-step explanation:
The sum of 22 and 33 by using distributive property will be; 55.
How to find Greatest common factor?The greatest common factor, as the name implies, is the greatest among all common factors among the quantities given.
We can factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could.
Factors:
22: 1 ,2, 11, 22
33: 1, 3, 11, 33
Both the numbers have a GCF of 11. Then by removing 11 from both numbers you end up with:
22 = 2 x 11
33 = 3 x 11
Now replace the values on the right of the equals sign into the original equation then;
(2 x 11) + ( 3 x 11)
The distributive property allows us to remove the common values and rewrite them;
11(2 + 3)
11(5)
55
The sum of 22 and 33 by using distributive property will be; 55.

What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction that can be written as the form of p : q, which is equivalent to p / q.
We need to find the fraction that is greater than 1/5 and less than 1/3
Since we know that 1/5 < 1/4 < 1/3
When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction that proper fraction is also called fraction which is less than 1.
Therefore the answer is; 1/4

A newspaper article reports the results of an election between two candidates. The article says that Smith received 60% of the votes and that Murphy received 15 of the votes. A reader writes in to complain that the article cannot be accurate. What reason might the reader have to say this?
Answers
Step-by-step explanation:
Since, smith receives 60% of the vote this means murphy must receive 40% of the vote. Therefore 15 = 40% of the total vote.
Thus total vote = 37.5, which is kind of absurd. As total vote count must be an integer. Moreover, the report must be consistent with the result, which does not seem in this case.

What is trapezoids ?Trapezoids are quadrilaterals that have two parallel sides and two non-parallel sides. It is also called a Trapezium. A trapezoid is a four-sided closed shape.
a pair of opposite sides are parallel.
diagonals of trapezium bisect each other.
sum of all four angles of trapezium is = 360°
it has four unequal sides.
diagonals are congruent.
opposite side of an isosceles trapezium are congruent.
According to the question
Trapezoids ABCD and EFGH are similar,
Hence, corresponding sides ratio are equal
Thus, AB/EF = DC/HG
24/x = 30/7.5
30x = 180
x = 180/30
x= 6
Hence, The length of EF is 6 cm
