what is g(x)?
a- g(x)=-x^2
b- g(x)=-lxl
c- g(x)=-2^x
d- g(x)=-x
Answer:
g(x) = -2^x
Step-by-step explanation:
This is an exponential function from the looks of the value for x as it decreases toward the negative value (increase in the absolute value calculation) y is constricted from its vigorous values down to the fractional components of an equation of the standard appearance of y = C^x. For this, try some values. x = 1 y = 2, x = 2 y = 4. There is a trend that is established through these points, and g(x) = -2^x seems to follow this trend as it is reflect across the x-axis. Enter points, it is confirmed and a graphing calculator further substantiates. Try for yourself!

The spinner below is spun. Find the probability that it lands on an odd number, given that it lands on a white space.
The probability that the spinner lands on an odd space given that it lands on the white space is 3/8.
The question is incomplete and the possible question is
The spinner given in the below image is spun. Find the probability that it lands on an odd number, given that it lands on white space.
What is Conditional Probability?The conditional probability of an event B on the hypothesis that another event A has occurred will be denoted by P(B|A) and defined by
P(B|A)=P(AB)/P(A)
provided P(A)≠0.
In case P(A)=0, the conditional probability remains undefined.
How to tackle the problem?The sample space has 16 events, out of which 8 events have white space.
And out of those 8 white spaces, 3 have odd numbers.
White events are 12,14,6,2,10,15,3,9.
White odd events are 3,9,15.
Hence, P(White odd)=3/16
P(White)=8/16=1/2
Thus, the probability that the spinner lands on an odd space given that it lands on the white space
=P(odd | White)
=P(White odd) / P(White)
=(3/16)/(1/2)
=3/8
Hence, the probability that the spinner lands on an odd space given that it lands on the white space is 3/8.

The tires on a mining truck are 14 ft tall. Which measurement is it (diameter, radius, or circumference)
Answer:
this is quite easy. if the tire is 14 ft. tall, that would mean the diameter is 14 ft. as well (do to a tire being round). the radius is half of the diameter, meaning the radius is 7 ft. finally, to find the circumference, you would have to multiply pi by 2 (6.28) then multiply this by the radius to make 43.98 ft.
Step-by-step explanation:
D = 14
R = 14/2 = 7
C = 2(pi) x 7 = 6.28 x 7 = 43.98

A caterer is preparing a dinner for a party. Shecharges an initial fee of $16 and $8.25 per person. How manypeople can attend a dinner that costs $131. 50? Write an equationand solve.
Answer:
The nomber of people can attend a dinner that costs $131. 50 is 14.
Step-by-step explanation:
With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:
c=16+8.25x, where:
c is the total cost of he dinner
x is the number of people
Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:
131.50=16+8.25x
131.50-16=8.25x
115.50=8.25x
x=115.50/8.25
x=14
According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.
if f(x) = 2x -3 what is the value of f(x) when x is -5?
Answer:
-13
Step-by-step explanation:
To find the value of f(x) when x is -5, substitute -5 for the x in the equation. Then, simplify:
[tex]f(x) = 2x-3\\\\f(-5) = 2(-5)-3\\f(-5) = -10-3\\f(-5) = -13[/tex]
So, when x is -5, the value of f(x) will be -13.

Find the side lengths of a triangle
Step-by-step explanation:
Each side of a square classroom is 8 yards long. The school wants to replace the carpet in the classroom with new carpet that costs $79.38 per square yard. How much will the new carpet cost?
Answer:
Total cost= $4,445.28
Step-by-step explanation:
Giving the following formula:
Each side of a square classroom is 8 yards long.
The new carpet costs $79.38 per square yard.
First, we need to calculate the total number of square yards needed:
Square yards of the classrom= 8*8= 56
Now, the total cost:
Total cost= total square yards*unitary cost
Total cost= 56*79.38
Total cost= $4,445.28

A system of equations is shown below. y=-x+3 y=3-/2 Does the ordered pair (-4, 6) satisfy the system? Justify your answer.
Answer:
(2.5, 5.5)
Step-by-step explanation:
The system of equation is not well written
Let the system of equations be;
y = x+3
y = 3x - 2
Equate both expressions to get x;
x + 3 = 3x - 2
x - 3x = -2-3
-2x = -5
x = 5/2
x = 2.5
Get the value of y;
y = x+3
y = 2.5+3
y = 5.5
Hence the required coordinate point is (2.5, 5.5)
Note that the second equation was assumed but the same steps can be taken to solve the given equation

At the local store, the cost of 1 pair of jeans is $24 and the cost of 3 pairs is $24 × 3 = $72. At the online store, the cost of 2 pairs of jeans is ($22 × 2) + $6 = $50 and the cost of 3 pairs is ($22 × 3) + $6 = $72.
Complete question :
Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and
ignore any taxes.
Answer:
$24, $72
$50
Step-by-step explanation:
From the table :
At local store :
2 pair of jeans cost $48
Cost of a pair :
Cost of 2 pairs / number of pairs
$48 / 2 = $24
Cost of 3 pairs :
Cost per pair * number of pairs :
$24 * 3 = $72
At online store :
Cost of Jean include a fixed fee of $6
Cost of one pair of Jean = $28
Actual cost of Jean :
$28 - $6 = $22
Hence, cost of 2 pair of jeans:
($22*2) + $6
$44 + $6 = $50

a manufacturer is designing a flashlight for the flashlight to admit a focused beam the bull needs to be on the central axis of the parabolic reflector 33 cm from the vertex write an equation that models the parabola formed when a cross section is taken through the reflector Center access assume that the vertex of the parabola is at the origin of the XY coordinate plane in the parabola can open it any direction
Answer:
y= 1/12(x-0)^2+0
this answer works as an upward parabola
Step-by-step explanation:
The formula for a veritcal parabola is y=1/4p(x-h)^2+k(h,k)= coordinates of the vertex of the parabolap= absolute value of the distance from the vertex to the focus/directrixIn this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex. Now, you know the values of the variables. Fill in the valuesFROM THE FORMULA: 1/4p turns into 1/12 since p is 3.(x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0once all the variables are given values (except x and y) you have made your equation! The answer is y=1/12(x-0)^2+0MARK BRAINLIEST! this took forever, and I know this is the right answer since I got a perfect grade when I turned mine in.
The equation of a parabola and the coordinates of the focus can be
expressed in terms of the coordinate of the vertex and the coefficient of
the quadratic term
The equation that models the parabola formed by taking a cross section
through the Center of the flashlight with focus 33 cm from the vertex is [tex]y \ \mathbf{ = \dfrac{x^2}{132} }[/tex]
The process by which the above equation is arrived at is as follows;
The given parameters of the parabolic reflector are;
The focus of the parabolic cross section of the reflector = 33 cm from the
vertex, along the central axis
The location of the vertex of the parabolic cross section = The origin of the XY coordinate plane = (0, 0)
The vertex form of the equation of a parabola is y = a·(x - h)² + k
Where;
(h, k) = The coordinate of the vertex of the parabola
The coordinate of the focus, f = (h, k + 1/(4·a))
In the given parabola, the vertex (h, k) = (0, 0)
Therefore;
h = 0, and k = 0
The vertex of a parabola is along the central axis, therefore, the equation
of the central axis is the vertical line, x = 0
The x-coordinate of the focus, is therefore, x = 0
From which from the distance of the focus from the vertex = The y-coordinate = 33
The coordinate of the focus is (0, 33)
Equating the above coordinate to the general form of the coordinate of a parabola (opening up or down), gives;
Coordinate of the focus, f = (h, k + 1/(4·a)) = (0, 33)
Therefore;
As above, h = 0
k + 1/(4·a) = 33
From k = 0 obtained above, we get;
0 + 1/(4·a) = 33
a = 1/(4 × 33) = 1/132
a = 1/132
The equation of the parabola is therefore found by plugging in the values
of a, h, and k in the equation, y = a·(x - h)² + k, as follows;
[tex]y = \dfrac{1}{132} \times \left(x - 0\right )^2 + 0 \ \mathbf{ = \dfrac{x^2}{132} }[/tex]
[tex]\therefore \mathbf{The \ equation \ of \ the \ parabola \ is \ y} \mathbf{ = \dfrac{x^2}{132} }[/tex]
