Identify the mistake.
The mistake is that it is 1/16 not 16. The person probably did the reciprocal or incorrectly used the fraction
Answer:
The exponent for the answer should be -2. Therefore, the answer will be 4⁻² or 1/16.
Step-by-step explanation:
When dividing fractions, you subtract the exponents as long as they have the same base.
Since the exponents both have the base of 4, subtract 9 - 11.
9 - 11 = -2
The exponent would be -2 and the answer would be 4⁻².
When an exponent is negative, you take the inverse of the base raised to the positive exponent.
Since 4² = 16 or 16/1, 4⁻² would be 1/16.
The answer would be 4⁻² or 1/16.
Hope that helps.
If y varies directly with x, find the value of y when x = 27 for the direct variation with the given information. y = 7 when x = -9 y =
Given:
y varies directly with x,
It is given that y = 7 when x = -9.
To find:
The value of y when x = 27 for the direct variation.
Solution:
It is given that y varies directly with x, so
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
It is given that y = 7 when x = -9. Putting these values in (i), we get
[tex]7=k(-9)[/tex]
[tex]-\dfrac{7}{9}=k[/tex]
Putting [tex]k=-\dfrac{7}{9}[/tex] in (i), we get
[tex]y=-\dfrac{7}{9}x[/tex]
Putting [tex]x=27[/tex], we get
[tex]y=-\dfrac{7}{9}(27)[/tex]
[tex]y=-21[/tex]
Therefore, the required value is [tex]y=-21[/tex].
Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode, she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone. Let D(t) denote the distance to the safe zone D (measured in meters) as a function of time t (measured in seconds).
Which of the below formulas is the correct function's formula?
A. D(t) = -25t + 160
B. D(t) = 25t + 160
C. D(t) = -25t - 160
D. D(t) = 25t - 160
Step-by-step explanation:
A. D(t) = -25t + 160
this is the correct answer because if you substitute 3 you get 85

Step-by-step explanation:
Solve 5x + 14 = k for x.
Answer:
x = (k-14)/5
Step-by-step explanation:
5x + 14 = k
Subtract 14 from each side
5x + 14-14 = k-14
5x = k-14
Divide by 5
5x/5 = (k-14)/5
x = (k-14)/5
Answer:
k - 14/5
Step-by-step explanation:
5x + 14 = k
On subtracting 14 on both sides,
5x = k - 14
On dividing by 5 on both sides,
x = k - 14/5
Therefore, the value of x = k-14/5

Range is the set of y-values that are outputted by function f(x)Interval Notation - [Brackets] denote inclusion and (Parenthesis) denote exclusionStep-by-step explanation:
According to the graph, our y-values span from -1 to 6. Since -1 is a closed dot, it is inclusive. Since 6 is an open dot, it is exclusive:
Range would then be [-1, 6).

3(h+6) = 2(-5-2h) Solve for h
Answer:
h = -4
Step-by-step explanation:
3(h+6) = 2(-5-2h) Solve for h.
Apply distributive property first on both sides.
3(h+6) = 2(-5-2h)
3h+18 = -10-4h
Next, put the terms with h on one side and the numbers on the other.
3h+18 = -10-4h
7h = -28
Divide both sides by 7 and you have your answer.
7h = -28
h=-4
Answer:
-4
Step-by-step explanation:
First, expand the brackets by multiplying the left bracket all by 3 and the right all by 2. This gives 3h+18=-10-4h.
You want h all on one side, so add 4h to both sides, leaving 7h+18=-10.
Subtract 18 on both sides to leave only h and the coefficient on the left. This gives 7h=-28.
Dividing both sides by 7 isolates the x and gives h=-4.

f(x)=x^2. what is g(x)
Answer:
g(x) = 0.5x²
Step-by-step explanation:
Since the graph of g(x) still passes through the origin and is u shaped, it is also a quadratic graph but with a different coefficient of x².
Let g(x) = ax²
When x=2, g(x) = 1
Hence, 2a = 1
a = 0.5
Therefore, g(x) = 0.5x²
The sum of three numbers is 10. Two times the second number minus the first number is equal to 12. The first number minus the second number plus twice the third number equals 7. Find the numbers.
9514 1404 393
Answer:
(-2, 5, 7)
Step-by-step explanation:
The problem statement lets us write three equations for the three numbers x, y, and z.
x + y + z = 10
-x + 2y = 12
x - y + 2z = 7
__
Adding the second equation to each of the other two gives ...
3y +z = 22
y +2z = 19
Subtracting the second of these from double the first gives ...
2(3y +z) -(y +2z) = 2(22) -(17)
6y +2z -y -2z = 44 -19
5y = 25
y = 5
z = 22 -3(5) = 7 . . . . . . from 3y+z=22
x = 10 -5 -7 = -2 . . . . . .from x+y+z=10
The numbers are (x, y, z) = (-2, 5, 7).

Find the probability that a randomly selected point within the circle falls in the white area. 60* 60* r = 4cm round to the nearest tenth of a percent
Answer:
66.7%
Step-by-step explanation:
Please find attached the complete question
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that a randomly selected point within the circle falls in the white area = degree occupied by white area / sum of angles in a circle
sum of angles in a circle = 360
degree occupied by white area = sum of angles in a circle - sum of degrees of shaded area
360 - (60 + 60) = 240
240 / 360

A cylinder has a volume of 200 cubic centimeters. If the height of the cylinder is 10 centimeters, what is the radius of the cylinder?
Answer:
The radius of the cylinder is 2.52 cm.
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h. We can solve this for r² by dividing both sides of the equation by πh:
r² = V / (πh)
Then the desired radius is found by taking the square root of this.
r = √{V / [πh]}
200 cm^2
Here, r² = ------------------- = 6.37 cm^2
3.14(10 cm)
and so r = √6.37 cm^2 = 2.52 cm
The radius of the cylinder is 2.52 cm.
Answer:
radius = 2.52 cm
Step-by-step explanation:
[tex]Volume = \pi r^2 h\\\\200 = \pi r^2 \times 10\\\\\frac{200}{10 \times \pi} = r^2 \\\\6.332 = r^2 \\\\\sqrt{6.332} = r \\\\r = 2.52 \ cm[/tex]
