Answer:
D. no function
Explanation:
We have a function because this graph passes the vertical line test. It is impossible to draw a single vertical line to have it pass through more than one point on the V shaped curve. Any x input leads to exactly one y output.
Even though we have a function, it is not one-to-one. Note how the curve fails the horizontal line test. It is possible to draw a horizontal line and have it pass through more than one point on the curve.
For example, draw a horizontal line through y = 3 and it passes through (-3,3) and (3,3) simultaneously. A one-to-one function is where any y output corresponds to exactly one x input, and vice versa. The output y = 3 corresponds to two different inputs x = -3 and x = 3 at the same time.
Why do we care about one-to-one functions? Well it's to help set up the inverse. The inverse goes the opposite direction of what the original function does. In this case, this function doesn't have an inverse unless we restrict the domain in some way.
A survey asks a random sample of 1500 adults in Ohio if they support an increase in the state sales tax from 5% to 6%, with the additional revenue going to education. Let ^ p denote the proportion in the sample who say they support the increase. Suppose that 47% of all adults in Ohio support the increase. The standard deviation of the sampling distribution is
Answer:
The correct response is "0.0129".
Step-by-step explanation:
Given:
[tex]n=1500[/tex]
[tex]p=0.47[/tex]
[tex]np=1500\times 0.47[/tex]
[tex]=705[/tex]
[tex]nq=1500\times (1-0.47)[/tex]
[tex]=795[/tex]
Mean of sampling distribution will be:
[tex]\mu_\hat{p}[/tex] = [tex]0.47[/tex]
hence,
The standard deviation will be:
⇒ [tex]\sigma_\hat{p}[/tex] = [tex]\sqrt{\frac{p(1-p)}{n} }[/tex]
By putting the values, we get
= [tex]\sqrt{\frac{0.47(1-0.47)}{1500} }[/tex]
= [tex]0.012886686[/tex]
= [tex]0.0129[/tex]
Can someone help with both questions 19 & 20
Answer:
19.
h=0, the result is 1000×2⁰ = 1000
this is the population of bacteria the excitement started with at the very beginning.
h=-3, the result is 1000×2-³ = 1000/(2³) = 1000/8 = 125
this is a calculation 3 hours backwards from the very start of the experiment, saying that if we started the experiment 3 hours earlier, this would have had to be the starting population of the bacteria so we would arrive at the same amount of population at any given time (value of h).
20.
D 25x⁶
Step-by-step explanation:
for 19 there is not more explanation. it is all ashtray in the answer.
for 20 we see that we are dealing with a square, so ask 4 sides have the same length.
one side is 5x³.
the area of a square is simply side².
so, here (5x³)² = 25x⁶

determine the period of this function
Explanation:
The function is somewhat sinusoidal but not entirely. Its composed of piecewise line segments when we should have a single continuous smooth curve; however, it's still periodic since it repeats itself.
Let's start at the top at the left most corner. This point has x coordinate of x = 1.
The other endpoint of this top left flat portion is when x = 2. Then the function curve goes downhill until it reaches x = 4. From x = 4 to x = 5, we're at the flat bottom part. From x = 5 to x = 7 is when the function increases.
Once we get to x = 7, the process described earlier starts all over again. So this is when the cycle ends and the length of the period is 7-1 = 6 units. The function repeats itself every 6 units, or you can say the length of each cycle is 6 time units (eg: 6 seconds).

Answer:You can also use tables to represent functions. Instead of using two ovals with circles, a table organizes the input and output values with columns. ... Remember, a function can only assign an input value to one output value. If you see the same x-value with more than one y-value, the table does not represent a function.

What is the effect on the graph of f(x) if it is changed to f(x) + 7, f(x + 7) or 7f(x)?
Step-by-step explanation:
The function f(x)+7 will shift the parent function up 7 units.
The function f(x+7) will shift the parent function to the left 7 units.
The function 7f(x) will stretch vertically by a factor of 7.
An ice cream cone is 4 in across and 6 in deep. A scoop of ice cream with a diameter of 4 inches is placed on top. If the ice cream completely melts, how much ice cream spills out of the cone? Round answer to two decimal places.
Answer:
8.373
Step-by-step explanation:
Cone
Find the volume of the cone
V = 1/3 pi r^2 h
r = d/2
r = 4/2
r = 2 inches
h = 6 inches
pi = 3.14
V = 1/3 * 3.14 * 2^2 * 6
V = 25.12
Half sphere
V = 1/2 (4/3) pi r^3
r = 2 from above calculation
pi = 3.14
V = 2/3 * 3.14 * 2^3
V = 2/3 * 3.14 * 8
V = 16.74
Nothing spills out so I scoop must be a whole sphere. The sphere is 2 times what I calculated it to be or
V = (4/3) * 3.14 * 2^3
V = 33.49 cubic inches
The difference in volume is 33.49 - 25.12 = 8.373

The length of a rectangle exceeds its width by 3 inches. The area of the rectangle is 70
square inches. Find its dimensions. Hint: as in the example, use the equation for area,
A = lw.
Answer:
70= (x+3)
Step-by-step explanation:
the length of the rectangle its width by 3 inches, if the width is x,the length will be x+3. so A=LW= 70
To find= 70= (x+3)x
x= 7 or -10
Find the area of the shape below.
11 cm
14 cm
9 cm
20 cm
Answer:
length divided by breadth divided by height
pls add me as brainliest
Solution:
20 - 1 1 = 9 cm
We can divide figure in 2 parts
rectangle = 14 cmx 11 cm
square = 9 cm x 9 cm
Area of rectangle = 14 * 11 = 154 cm²
Area of square = 9 * 9 = 81 cm²
Total area = 154 + 81
= 235 cm²

The functions f(x) and g(x) are described using the following equation and table:
f(x)=-4(1.09)x
Given:
The function is:
[tex]f(x)=-4(1.09)^x[/tex]
The table of values for the function g(x).
To find:
The equation that best compares the y-intercepts of f(x) and g(x).
Solution:
We have,
[tex]f(x)=-4(1.09)^x[/tex]
Putting [tex]x=0[/tex], we get
[tex]f(x)=-4(1.09)^0[/tex]
[tex]f(x)=-4(1)[/tex]
[tex]f(x)=-4[/tex]
So, the y-intercept of the function f(x) is -4.
From the given table of values, it is clear that the function f(x) passes through the point (0,-4). So, the y-intercept of the function g(x) is -4.
The y-intercept of f(x) is equal to the y-intercept of g(x).
Therefore, the correct option is A.
Answer:
A) The y-intercept of f(x) is equal to the y-intercept of g(x).
