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

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
Situation: Find the substance's half-life, in days. Round your answer to the nearest tenth. A 33 gram sample of a substance that's used for drug research has a k-value of 0.1081. Enter the correct answer. N = Noe DONE No = initial mass (at time t = 0) 000 OO N = mass at time t k= = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
Answer:
1051 or..
10.51
Step-by-step explanation:
Since 33=30 and 0.1081 is supposed to be as a percentage since its already a decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number. Answer: 1051 or as a decimal 10.51

volume of cylinder with a base radius of 5 and height of 3
Answer:
235.5.
Step-by-step explanation:
VOLUME: THE AMOUNT OF SPACE OCCUPIED BY A 3D OBJECT.
The formula for volume of a cylinder is:
[tex]pi*r^2*h (3.14 * radius *radius * height)[/tex]
The radius of this cylinder is 5 and the height is 3.
Now, we can plug the numbers in the formula.
SOLVE:
[tex]pi *5^2*3(3.14*5*5*3)=235.5.[/tex]
The product of the equation is 235.5.
I, therefore, believe the volume of this cylinder is 235.5.

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.

Simply plug in the 2 coordinates into the distance formula to find distance d

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.

Answer the answer is a 15.81
Step-by-step explanation:
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.
