Answer: D
Step-by-step explanation:
The parent function abs(x) is a V, similar to graph B.
When it is multiplied by a negative number then it reflects across the Y axis, and if the number is greater than 1, then the graph is horizontally compressed (like you're squishing the sides together, closer to each other). If the number is less than 1, either decimals or a fraction, then it is stretched (like you are pulling the sides away from each other and they are getting wider).
In this case you are multiplying abs(x) by 4, which is greater than 1 so it is compressed by a factor of 4, and then multiplying it by a negative, which reflects it across the y axis.

Your redecorating your bedroom, and you want to put in a dressing table. The wall where you want to put it measures 4.7m. There is also a cupboard door on this wall, which takes up 410mm. The dressing table you like is 123cm wide. Once you've bought the dressing table , how much space on the wall, do you have left, not including the cupboard doors? I need this working out in metres please.
Answer:
3.06 meters
Step-by-step explanation:
The first thing you want to do, since we are working with different units here, is find out how many centimeters make a meter... and so on.
1cm = 0.01m
1mm = 0.001m
123cm = 1.23m (Dressing table)
410mm = 0.41m (Cupboard door)
Now all we need to do is subtract.
We can add the two numbers together or (If you prefer) subtract separately.
1.23 + 0.41 = 1.64
Now subtract that number from the measurement of the wall:
4.7 - 1.64 = 3.06
The amount of space left is 3.06m.
During a test, 3 out of 100 cars selected at random were found to be defective. Use this ratio to estimate the number of defective cars if 1,500 cars are tested.
There are 45 defective cars if 1,500 cars are tested.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.
Given that;
During a test, 3 out of 100 cars selected at random were found to be defective.
Now,
Since, During a test, 3 out of 100 cars selected at random were found to be defective.
Let number of defective cars if 1,500 cars are tested = x
So, By definition of ratio, we get;
⇒ 3 / 100 = x / 1,500
Solve for x as;
⇒ 3 × 1500 / 100 = x
⇒ 3 × 15 = x
⇒ x = 45
Thus, There are 45 defective cars if 1,500 cars are tested.

Is the sum of 3.04 and √20 rational or irrational? Explain.
Answer:
Irrational
Step-by-step explanation:
A rational number can be expressed as p/q where p and q are integers
3.04 is rational since it can be expressed as 304/100
√20 is not rational. √20 = √(4·5) = √4·√5 = 2√5
While 2 is a rational number, √5 is irrational since 5 is a prime number and square roots of primes are not rational
An irrational number multiplied by a rational number is irrational so √20 is irrational
An irrational number added to a rational number results in an irrational number.
So 3.04 + √20 is irrational
Math Please help!!!!! Linear vs Exponential
Answer:
linearadditivelycommon differenceabout 240.12Step-by-step explanation:
Given the values in the table, you want to know if they represent a linear or exponential relation, along with the common difference or ratio, as applicable.
ChangesThe first attachment shows the differences and ratios between successive table values. Neither the differences nor the ratios are constant. The wide variation in ratios and the relatively smaller variation in differences suggests the table is best modeled by a linear function.
Changes when the function is linear are additive. That is, the function values have a common difference.
Common differenceThe average difference between table values is (949.92 -229.44)/3 = 240.16. A linear regression analysis gives a slope of 240.12 as the "best fit" to the table values.
You can see from the first attachment that the differences are not constant, so there isn't really a common difference. The difference is approximately 240.12.
__
Additional comment
The second attachment shows linear and an exponential regression applied to this data. The residuals are much smaller for the linear approximation.
The slope of the line (common difference) is estimated at 240.12 using the regression formula. This makes the mean square residuals a minimum. As we show above, this slope is different (slightly lower) than the slope of the line through the first and last data points.
The radius of a cone is 2.5 units. The volume of the cone is 19 cubic units
The formula for the volume of a cone is given by the following equation:
V = 1/3 * π * r2 * h
where V is the volume of the cone, r is the radius of the cone, and h is the height of the cone.
In this case, we are given that the radius of the cone is 2.5 units and the volume of the cone is 19 cubic units. We can use this information to complete the expression that represents the height of the cone as follows:
V = 1/3 * π * r2 * h
19 cubic units = 1/3 * π * 2.5 units2 * h
19 cubic units = 1/3 * π * 6.25 units2 * h
19 cubic units = 1/3 * 19.63 units2 * h
19 cubic units = 6.54 units2 * h
h = 19 cubic units / 6.54 units2
h = 2.9 cubic units / 6.54 units
Therefore, the expression that represents the height of the cone is 2.9 cubic units / 6.54 units.
What number represents 3,675,100,608 rounded to the nearest million?
The number 3,675,000,000 represents 3,675,100,608 rounded off to the nearest million.
Rounding off large numbers.When we round off large numbers, we consider the digit to the right of the number occupying the place value for which we are rounding off to. If the digit to the right is 4 or less, we round down (we leave the number we are rounding to), but if the digit is 5 or higher, we round up (we increase the digit we are rounding by 1). and thus round to the indicated place value.
From the question, we have the large number;
3,675,100,608
the digit 5 indicates the place value (million)
and the digit 1 is to the right and will be rounded down.
Therefore, the number 3,675,000,000 represents 3,675,100,608, rounded to the nearest million.

f(x)=1/2x+8 reflect x axis
The function of reflect x-axis is g(x) = -(1/2)*x - 8, according to the question.
What do you mean by function?
A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
According to the given question,
First, let's define a reflection over the x-axis.
If we have a point (x, y) and we reflect it over the x-axis, our new point will be (x, -y).
Now, when we have a function
f(x) = y, the points can be written as:
(x, y = f(x) ) = (x, f(x))
Then, after the reflection over the x-axis, we have:
(x, y = g(x)) = (x, -f(x))
So now we have g(x) = -f(x)
and we know that f(x) = (1/2)*x + 8
then our new function is g(x) = y = -f(x) = -( (1/2)*x + 8) = -(1/2)*x - 8.
g(x) = -(1/2)*x - 8.
Therefore, the required answer is g(x) = -(1/2)*x - 8.

Is (x + 7) a factor of f(x) = x3 − 3x2 + 2x − 8? Explain your reasoning.
X + 7 is not a factor of [tex]x^{3}[/tex] -3[tex]x^{2}[/tex] +2x -8 because it gives a remainder when x + 7 divides it.
What is a remainder?The remainder is the portion of the dividend that cannot be fairly divided by the divisor. After dividing whole numbers to find the quotient, the part that is left is called the remainder.
to know if x + 7 is a factor, x = -7 when substituted should give 0 as a remainder otherwise it is not a factor.
By substituting x = -7 we have
[tex](-7)^{3}[/tex] [tex]-3(-7)^{2}[/tex] +2(-7) - 8 = -343 -147 -14 - 8 which is -512
Therefore x + 7 is not a factor of the function.

165.8
282.6
306.6
565.2
Answer:
Volume = 282.6 ft.²
Step-by-step explanation:
Volume: V = πr²h
Step 1: The answer needs to be in cubic feet, so convert all units to feet
1. 3 ft./12 in. = 0.25 ft.
Step 2: Subtract 0.5 ft from 6.5 ft to find the actual diameter of the pipe that the water will be passing through
2. 6.5 ft. - 0.5 ft. = 6 ft.
Step 3: Plug 3 ft. (radius), 3.14 for π, and 5 ft for h
3. V = (3.14)(3 ft.)²(5 ft.)
Step 4: Solve for the V (volume)
4. V = (3.14)(9 ft.)(5 ft.) → V = (28.26)(5) → V = (28.26)(5) → V = 141.3 ft.²
Step 5: Divide 141.3 by 2, since we want half the capacity
5. 141.3 ft.²/2 = 70.65 ft.²
Step 6: Multiply 70.65 by 4 since we want the total volume of water passing through four pipes
6. 70.65 ft.² ∙ 4 = 282.6 ft.²
