The end of a hose was resting on the ground, pointing up an angle. Sal measured the path of the water coming out of the hose and found that it could be modeled using the equation f(x) = –0.3x2 + 2x, where f(x) is the height of the path of the water above the ground, in feet, and x is the horizontal distance of the path of the water from the end of the hose, in feet. When the water was 4 feet from the end of the hose, what was its height above the ground?

Good Luck! ;D
The expressions that give perfect square trinomials are:
[tex]x^2+14x + 49[/tex] and [tex]x^2-24x+144[/tex]
A quadratic trinomial of the form [tex]ax^2+bx+c[/tex] is a perfect trinomial if it can be expressed as [tex](mx + n)^2[/tex]
Let us consider [tex]x^2+14x + 49[/tex]
[tex]x^2+14x+49\\x^2+7x+7x+49\\x(x+7)+7(x+7)\\(x+7)(x+7)\\(x+7)^2[/tex]
Let us consider:
[tex]x^2-24x+144\\x^2-12x-12x+144\\x(x-12)-12(x-12)\\(x-12)(x-12)\\(x-12)^2[/tex]
All other options do not give a perfect square when tested
Therefore, the expressions that give perfect square trinomials are:
[tex]x^2+14x + 49[/tex] and [tex]x^2-24x+144[/tex]

Nicole has $9 to spend on cards.She finds friends with the same amount of money to split the cost of a set. One set cost $27. Each friend gets the same number of cards. How many cards does each friend get?
Answers
Answer: Number of cards each friend gets is given by
[tex]\frac{x}{3}[/tex]
Step-by-step explanation:
Let the number of cards be x.
Since we have given that
Amount Nicole used to spend on cards = $9
Total cost of one set =$27
Since she finds friends with the same amount of money to split the cost of a set.
So, Number of friends she finds is given by
[tex]\frac{27}{9}=3\\\\\text{ Nicole finds 2 friends who has same amount to split the cost}[/tex]
Now, Number of cards each friend gets is given by
[tex]\frac{x}{3}[/tex]
Lucie drank 3/4 of a pint of bottled water. One serving of the water is 7/8 of a pint. How much of a serving did she drink.
Answers
3/4
I'm order for them to have the same denominator you need to multiply so:
¾×2=6/8
So she drank 6/8 pints of water
3/4 x 2/2 = 6/8
So Lucie drank 6/8 of a pint, or 75% of it. 7/8 - 6/8 = 1/8. So there is 1/8 of water left, or 12.5%.

There was 2/3 of a pizza for 6 friends to share equally. What fraction of the pizza did each person get
Answers
However, if you can't do that (maybe all your phones have been abducted by aliens), then use easy division of fractions to solve.
2/3 divided by 6 is equal to 2/3 times 1/6.
When you divide a fraction, you have to flip the thing your dividing by and multiply it to the original number. I know, confusing stuff, right?
2/3*1/6
=2/18
=1/9
Each person gets 1/9 of the pizza.
Hope this helps (and that the aliens give you your phones back)!
Each person get 1/9 of a pizza.
What is Fraction?
A fraction is defined as a part of a whole.
Given that;
There was 2/3 of a pizza for 6 friends to share equally.
Now,
Total amount of pizza = 2/3
Number of friends = 6
So, For finding the amount of pizza get by each person we formulate.
= 2/3 × 1/6
= 2/18
= 1/9
Thus, Each person get 1/9 of a pizza.

Line R T and line S U slightly inclined with horizontal intersects at V. The upward and downward angles of the intersecting lines are obtuse. The left and right angles of the intersecting lines are acute. The measure of angle R V U is labeled as left parenthesis 8 y minus 33 right parenthesis degrees. The measure of angle S V T is labeled as left parenthesis 5 y plus 9 right parenthesis degrees.
Answers
5y+9=8y-33 vertical angles are congruent
-5y -5y
9 = 3y -33 Use inverse operations to move all variables to one side of the equation
+33 +33 Add 33 to both sides of the equation to isolate the variable
42=3y
/3 /3 Divide both sides by 3 in order to isolate the variable
14 = y Once simplified, the variable y is equal to 14
In order to find the measure of the angle, the value of the variable needs to be substituted back into one of the equations.

I need an answer what is 1.03 ÷ (-10.3)=?
Answers
To figure this out, convert both numbers to fractions. 1.03 = 1[tex]\frac{3}{100} [/tex] and (-10.3) = -10[tex] \frac{3}{10} [/tex]. Now, convert to improper fractions.
1[tex] \frac{3}{100} = [tex] \frac{103}{100} [/tex]
-10[tex] \frac{3}{10} [/tex] = [tex]- \frac{103}{10} [/tex]
Now, divide. Dividing fractions is the same as multiplying by the reciporical. So:
[tex] -\frac{103}{10} \ becomes\ \frac{10}{103} [/tex]
[tex] \frac{103}{100} *- \frac{10}{103} = -\frac{1030}{10300} = - \frac{1}{10} [/tex]
The answer to 1.03 ÷ (-10.3) is -0.1.
Explanation:To divide 1.03 by -10.3, you can use the division algorithm. Divide the absolute values of the two numbers and obtain the quotient. Since the signs of the two numbers are different, the quotient will be negative. Therefore, 1.03 ÷ -10.3 = -0.1.

The perimeter of a rectangle is 524cm. The length is is 42cm more than the width. What is the length of the rectangle?
Answers
Width= 215cm
Length= 173cm
Then P = 2W + 2L
Here, P = 524 cm = 2W + 2(W+42) = 2W + 2W + 84 = 4W + 84
Solving 524 = 4w + 84, 4W = 524-84 = 440.
Dividing both sides by 4: W = 110 cm. Then L = 110+42 = 152.
Check: Does 2(110) + 2(152) = 524? YES
W = 110 cm and L = 152 cm

Which statement is true about the result of a rigid transformation? (4 points)
The image will be larger than the pre-image.
The pre-image will be larger than the image.
Each one is unique; no general statement can be made about size.
The pre-image will be congruent to the image
Answers
Answer:
The pre-image will be congruent to the image : True
Step-by-step explanation:
The transformation falls broadly into two types.
Rigid Transformation and Non Rigid Transformation .
Rigid Transformation: The new image has the same size and the shape as that of pre image. Thus both the images are congruent to each other.
Non Rigid Transformation : The new image is has the same shape. however the size of the new image changes. hence they are similar to each other but not congruent.
Hence our third option is correct.

To use the Rational Zeros Theorem to find all possible rational zeros of the function f(x) = -2[tex]x^{4}[/tex] + 4[tex]x^{3}[/tex]+ 3[tex]x^{2}[/tex] + 18, we need to look at the factors of the constant term and the leading coefficient. For the constant term (18), the factors are
±1, ±2, ±3, ±6, ±9, ±18. For the leading coefficient (-2), the factors are ±1 and ±2. According to the Rational Zeros Theorem, the possible rational zeros are obtained by taking all the factors of the constant term and dividing them by the factors of the leading coefficient.
The list of all possible rational zeros is ±1, ±2, ±3, ±6, ±9, ±18, ±1/2, ±3/2, ±9/2, and ±18/2.
