Answer:
Step-by-step explanation:
I'm assuming that you are solving for x, since there's nothing else you can do with this mathematically.
[tex]\frac{1}{2}x=-9[/tex] and the goal is to get the x all alone. So we have to lose the fraction. Do that by multiplying by the reciprocal of 1/2 which is 2/1 (a reciprocal is just a fraction flipped upside down). BUT...because this is an equation, what you do to the left side has to be done to the right side too. Like this:
[tex](\frac{2}{1})\frac{1}{2}x=\frac{-9}{1}(\frac{2}{1})[/tex]
On the left, everything cancels out but the x (which is why we do this), and on the right we multiply straight across the top and straight across the bottom to get
[tex]x=\frac{-18}{1}[/tex] which is
x = -18
Simplify. (-18x^3 +17x+6)÷(3x+2)

A baseball is thrown into the air from the top of a 224-foot tall building. The baseball's approximate height over time can be represented by the quadratic equation h(t) = -16t2 + 80t + 224, where t represents the time in seconds that the baseball has been in the air and h(t) represents the baseball's height in feet. When factored, this equation is h(t) = -16(t - 7)(t + 2).
What is a reasonable time for it to take the baseball to land on the ground?
A.
5 seconds
B.
9 seconds
C.
2 seconds
D.
7 seconds
Answer:
D. 7s
Step-by-step explanation:
h(t) = height off the ground
We know the height of the ball at the point when it hits the ground will be 0, so we set h(t) = 0:
h(t) = -16(t - 7)(t + 2) = 0
In order for this to be true, either:
"t - 7 = 0" or "t + 2 = 0"
We can solve these to get the times at which the ball will hit the ground, which gives:
t = 7 or t = -2
-2s is not a logical time because the ball can't hit the ground before it is thrown so this solution is not relevant;
7s therefore is the correct solution

CDE is reflected over the x axis . what are the vertices of c'd'e
please help!! <3
Answer:
last option is correct
Step-by-step explanation:
use formula of reflection over x axis .
The coordinates of C , D , E are (-8 , -1) , (-6 , -5) , (-2 , -4) respectively.
formula :
(x , y) = (x -y)
C(-8 , -1) = C'(-8 , 1)
D(-6 , -5) = D'(-6 , 5)
E(-2 , -4) = E'(-2 , 4)
Answer: Choice D (aka 4th option)
C ' (-8, 1)
D ' (-6, 5)
E ' (-2, 4)
===========================================================
Explanation:
The x axis reflection rule is [tex](x,y) \to (x,-y)[/tex]
x stays the same while y flips in sign (positive to negative, or vice versa).
A point like C(-8, -1) will reflect to C ' (-8, 1)The point D(-6, -5) reflects to D ' (-6, 5)Lastly, the point E(-2, -4) reflects to E ' (-2, 4)All of this points to Choice D as the final answer.

Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
Substitute in points [Distance Formula]: [tex]\displaystyle d = \sqrt{(1--5)^2+(8-3)^2}[/tex][√Radical] (Parenthesis) Subtract: [tex]\displaystyle d = \sqrt{(6)^2+(5)^2}[/tex][√Radical] Evaluate exponents: [tex]\displaystyle d = \sqrt{36+25}[/tex][√Radical] Add: [tex]\displaystyle d = \sqrt{61}[/tex][√Radical] Evaluate: [tex]\displaystyle d = 7.81025[/tex]Round: [tex]\displaystyle d \approx 7.81[/tex]Answer:
AB = 7.81
Step-by-step explanation:
Distance between 2 points = sqrt( (x2 - x1)^2 + (y2 - y1)^) )
x2 = - 5
x1 = 1
y2 = 3
y1 = 8
D = sqrt( -5 - 1)^2 + (3 - 8)^2 )
D = sqrt( (-6)^2 + (-5)^2 )
D = sqrt( (36 + 25)
D = sqrt( 61)
D = 7.81

For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
A. Axis of symmetry: x = 0.5; Vertex: (0.5, –1); f(x) = x2 – x – 1
B. Axis of symmetry: x = 0.5; Vertex: (0.5, –1.25); f(x) = x2 – x – 1
C. Axis of symmetry: x = –0.5; Vertex: (–0.5, 1.25); f(x) = x2 – x – 1
D. Axis of symmetry: x = 0.5; Vertex: (0.5, –1.25); f(x) = x2 + x – 1
Answer:
Axis of symmetry: x = 0.5; Vertex: (0.5, –1.25); f(x) = x2 – x – 1
I THINK IT'S THIS ANSWER Axis of symmetry: x = 0.5; Vertex: (0.5, –1); f(x) = x2 – x – 1
Step-by-step explanation:
Answer:
The answer to your question is the third choice.
Step-by-step explanation:
The axis of symmetry is the dotted red line which is located in x = 1/2
The Vertex is the lowest point of the parabola which is (1/2, -1)
The equation of the function is:
(x - h)² = 4p(y - k)
-Substitution
(x - 1/2)² = 4p(y + 1)
-We can not know the value of p
x² - x + 1/4 = y + 1
Discarding choices, there are two possible answer, the second and the third choices, but because of the Vertex (0.5, -1), i think the right answer is the third choice.

Gabriella is flying a kite, holding her hands a distance of 3.75 feet above the ground and letting all the kite’s string play out. She measures the angle of elevation from her hand to the kite to be 36^{\circ}
∘
. If the string from the kite to her hand is 140 feet long, how many feet is the kite above the ground? Round your answer to the nearest tenth of a foot if necessary.
Answer:
the answer is 86ft
Step-by-step explanation:
The height of the kite above the ground is 86 feet.
Trigonometric ratio is used to show the relationship between the sides of a triangle and its angles.
Let h represent the height of the kite. Hence, using trigonometric ratios:
sin(36) = h / 140
h = 82.28 feet
Kite height above ground = 3.75 + 82.28 = 86 feet
Therefore the height of the kite above the ground is 86 feet.

2x = 4y + 8, x - 2y = 4
Answer: x = 8, y = 2, coordinates (8,2)
Step-by-step explanation:
2x = 4y + 8 (divide by 2 to get value of x)
x = 2y + 4
(now substitute x into the second equation to find value of y)
2y + 4 - 2y = 4
2y - 2y = 4 - 4 (divide by 2 to get value of y)
y - y = 2 - 2
y = 2
Now plug in value of "y" to get value of "x".
x - 2(2) = 4
x - 4 = 4
x = 8
Coordinates (8,2)
8. An car can hold 8 1/4 gallons of fuel. It contains 4 5/6 gallons of fuel. How
much more fuel is needed to fill the car?
Answer:
3 5/12
Step-by-step explanation:
Answer:
41/12 gallons
= 3 5/12 gallons
Step-by-step explanation:
Since it can hold 8 1/4 gallons and currently has 4 5/6 gallons, you subtract.
You need to get the common denominator to subtract cleanly so we can turn the fractions into improper fractions.
8 1/4 = 33/4 because 8 is equal to 8 full 4/4ths so multiply 8 by 4 and add 1 for the remaining 1/4.
Then 4 5/6 becomes 29/6 with the same concept earlier.
So we can change the denominator to 12 on both fractions (33/4 and 29/6) so we can subtract.
33/4 becomes 99/12 because they are still equivalent, it's just that you multiplied the top and bottom by the same number.
29/6 becomes 58/12 because we multiplied the fraction by 2/2.
Those two new fractions stated previously are the same as the original because we multiplied them by 1/1, because 3/3 and 2/2 is still equal to 1/1, and the new fractions can be simplified down to the original.
Since we have 99/12 and 58/12, we can subtract cleanly into
99 - 58 = 41
So the answer is 41/12
