Answer:
Yes, a transformation of f in the form g(x) =f(x)+k can have no x-intercepts. This will occur if the constant k is added to the y-value of every point on the f(x) graph, resulting in the chart of g(x) being shifted upward by k units. If the original diagram of f(x) had no x-intercepts, then the graph of g(x) would also have no x-intercepts because the x-coordinate of each point on the graph of f(x) is unchanged by the transformation.

Ivan's company makes solid spherical balls out of scrap metal for various industrial uses. A large order just came in to make lead balls with a radius of 3in. If Ivan uses, on average, 28,260in3 of lead each day making these balls, how many balls does he make, on average, each day?
If necessary, refer to the list of geometry formulas.
For your calculations, do not round any intermediate steps, and use the π button on the ALEKS calculator. Round your answer to the nearest hundredth.
balls
Answer: To find the number of balls Ivan makes each day, we need to divide the total volume of lead used each day by the volume of one ball.
The formula for the volume of a sphere is:
V = (4/3) * π * r^3
Where V is the volume, π is pi and r is the radius of the sphere.
We know the radius of the sphere is 3 inches so we can use this information to find the volume of one ball.
V = (4/3) * π * 3^3
V = (4/3) * π * 27
V = 36 * π
Now we know the volume of one ball is 36π cubic inches, we can divide the total volume of lead used per day by the volume of one ball to find the number of balls made per day.
28,260 in^3 / 36π in^3/ball = 785.833 balls/day
Rounding to the nearest hundredth, Ivan on average makes 785.83 balls/day.

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 2 sin Ït + 4 cos Ït, where t is measured in seconds. (Round your answers to two decimal places.)(a) Find the average velocity during each time period.i. [1,2]ii. [1,1.1]iii. [1.1.01]iv. [1.1.001]
The average speed throughout the given time was [1,2] = -2.00 cm/sii. -0.26 cm/siii for [1,1.1]. [1.1,1.01] = 0.17 cm/siv. [1.1,1.001] = 0.02 cm/s
The particle's displacement divided by the passage of time represents its average velocity at each time interval. The displacement of the particle for the above motion equation is given by s = 2 sint + 4 cost. By subtracting the displacement at the beginning and end of the period and dividing it by the change in time, we can determine the average velocity for each time period. As an illustration, the displacement for the time period [1,2] is 2 sin + 4 cos at the beginning of the period and 2 sin + 4 cos at the end of the period. These two figures differ by -4, and one second has passed between them.

Triangle A C B is cut by line segment E D. Line segment E D goes from side B C to side A C. The length of B A is 4 x minus 6 and the length of E D is x + 2. The length of B E is x. Sides B E and E C are congruent. Sides A D and D C are congruent.
What is the length of BC?
From the markings on the diagram, we can tell E is the midpoint of BC and
D
is the midpoint of AC
We can apply the
theorem: ED = One-halfBA.
Substituting in the expressions for the lengths and solving for x, we get x =

Applying the Midsegment Theorem, the length of BC is: 10.
What is the Midsegment Theorem?The Triangle Midsegment Theorem states that in a triangle, a line segment connecting the midpoints of two sides is parallel to the third side and is half as long.
From the information given we know that:
E is the midpoint of BC and D is the midpoint of AC.
Thus, applying the Midsegment Theorem, we have:
ED = 1/2(BA)
Substituting the values not expressive, we would get:
x + 2 = 1/2(4x - 6)
2(x + 2) = 4x - 6
2x + 4 = 4x - 6
2x - 4x = -4 - 6

A bag of m & m is dumped on the table and you count 82 blue pieces.approximately how many m&ms do you expect to be in the entire bag based on the entire class. Round to the nearest whole m&m
Answer: Based on the information provided, we can use the proportion of blue m&ms found in the sample (82 out of some larger total number of m&ms) to estimate the total number of m&ms in the entire bag.
If we let x be the total number of m&ms in the bag, we can set up the proportion:
82/x = blue m&ms / total m&ms
To solve for x, we can cross-multiply and divide by 82:
x = 82 * total m&ms / blue m&ms
x = 82 * 1
x ≈ 82
Therefore, based on the sample, we expect there to be approximately 82 m&ms in the entire bag, rounded to the nearest whole m&m.
It's worth noting that this is an estimation, and the actual number of m&ms in the bag may be different.
Step-by-step explanation:
a norman window has the shape of a rectangle surmounted by a semicircle. if the perimeter of the window is 30 ft, express the area a of the window as a function of the width x of the window.
The area a of the window as a function of the width x of the window 12x -(4 + π)x2/8
Let y be the height of the window's rectangular part, and let P represent the window's perimeter.
P then equals x plus 2y plus the length of the semicircular part. The radius of the semicircular part is x/2.
So, P = x + 2y + (1/2)(circumference)
P = x + 2y + (1/2)(2)π(x/2)
P = x + 2y +πx/2 = 24
2y = 24 - x - πx/2
y = 12 - x/2 - πx/4 = 12 - (2 + π)x/4
A = xy + (1/2)π(x/2)2
= x(12 - (2 + π)x/4) + πx2/8
= 12x -(2 + π)x2/4 + πx2/8
= 12x - (4 + 2π)x2/8 + πx2/8
= 12x - 4x2/8 - πx2/8

3xcube+x-200 divide by x-4
When will divide (3x³+x-200) by (x-4) will get 3x²+12x+49 and -4 as remainder.
What is division?Division is the process of splitting a number or an amount into equal parts.
Given is an expression, 3x³+x-200 which is divided by x-4,
Therefore,
(3x³+x-200) / (x-4)
Step 1)Divide the leading term of the dividend by the leading term of the divisor:
3x³/x = 3x²
Multiply it by the divisor: 3x²(x−4)=3x³−12x²
Subtract the dividend from the obtained result:
(3x³+x−200)−(3x³−12x2) = 12x²+x−200
Step 2)Divide the leading term of the obtained remainder by the leading term of the divisor: 12x²/x = 12x
Multiply it by the divisor: 12x(x−4) = 12x²−48x
Subtract the remainder from the obtained result:
(12x²+x−200)−(12x²−48x) = 49x−200
Step 3)Divide the leading term of the obtained remainder by the leading term of the divisor: 49x / x = 49
Multiply it by the divisor: 49(x−4) = 49x−196
Subtract the remainder from the obtained result:
(49x−200)−(49x−196) = −4

Finding the number of teachers:To find the number of teachers that teach only Science we can subtract the number of teachers who teach both subjects from the number of teachers that teach science.
Similarly, to find the number of teachers that teach only Humanities we can subtract the number of teachers who teach both subjects from the number of teachers that teach Humanities.
To find the number of teachers who teach Humanities or science we use the elementary set formula,
n(A ∪ B) = n(A) + n(B) - n(A ∩ B)Here we have
Total number of teachers = 100
No of teachers who teach Humanities, n(H)= 25
No of teachers who teach Science, n(S) = 60
No of teachers who teach both Science and Humanities, n(H ∩ S) = 15
The number of teachers who teach science but not humanities
= No of teachers who teach Science - No of teachers who teach both
= 60 - 15 = 45
The number of teachers who teach Humanities but not science
= No of teachers who teach Humanities - No of teachers who teach both

The percentage that the offspring will be deaf is 75%. Two punnet squares are needed each for km and Kkmm individuals. In punnet square 1, half of the genotypes are Km and km while half are Mm and kk in punnet square 2. The two punnet squares are then combined to form a final one where a quarter of the offspring is deaf.
What does genotype mean?
In a wide sense, the word"genotype" refers to the genetic makeup of an organism; it defines an organism's complete set of genes. In a more thin sense, the term can be used to guide the alleles, or variant forms of a gene, that are carried by an organism.

Write the following set as an interval using interval notation.
{x|−7
Answer: The set {x|−7 < x} can be written in interval notation as (-infinity, -7) < x.
This set represents all real numbers greater than -7. The interval notation uses the less-than symbol (<) to represent that all values of x greater than -7 are included in the set. The interval notation uses the infinity symbol to represent the fact that there are no limits on the lower end of the interval.
It's important to note that the interval notation includes the endpoint values when it is in the form of (a,b) or [a,b) but it does not include endpoint values when it is in the form of (a,b] or [a,b].
